version 2.03.22 - 02nd August 2023
==================================
report: fix pv_major and pv_minor report field type We incorrectly marked pv_major and pv_minor fields as being of string type, even though the values were already correctly handled as integers internally. This confused -S|--select that tried to compare string values instead of integers. Reported here: https://github.com/lvmteam/lvm2/issues/122
2023-07-31 14:37:34 +03:00
Fix pv_major/pv_minor report field types so they are integers, not strings.

WHATS_NEW: update
2023-08-02 15:38:23 +03:00
Fix parsing of VDO metadata.
reporter: restore report type to initial value after processing report_for_selection If we are executing 'report_for_selection' to do an internal report just for the selection itself (not for display), we can call it more than once. In that case, we are reusing the same selection handle (e.g. inside 'process_each_lv_in_vg'). The selection handle has 'report_type' field which is a union of all report types needed for the report based on selection fields we actually use. The 'report_type' is further clarified based on checks and rules inside '_get_final_report_type' which 'report_for_selection' calls. Then, this final report type unambiguously identifies proper branch to take in 'report_all_in_{pv,vg,lv}' that is called next. If the 'report_for_selection' is called more than once with the same selection handle, we need to make sure that we always restore the report type to its initial value, so all the rules inside 'report_for_selection' are applied correctly next time. This patch fixes the missing restoration of the 'report_type' value in 'selection_handle' that is reused for recurring 'report_for_selection' calls. An example scenario where this failed was with selecting an LV for removal with "lvremove --select" while using a field in the selection that required extra DM info or DM status call for the LV (that is, "Logical Volume Device Info Fields" and "Logical Volume Device Status Fields" as visible in 'lvs -S help').
2023-05-30 22:14:37 +03:00
Fix failing -S|--select for non-reporting cmds if using LV info/status fields.

version 2.03.20 - 21st March 2023
=================================
toollib: fix segfault if using -S|--select with log/report_command_log=1 setting When we are using -S|--select for non-reporting tools while using command log reporting (log/report_command_log=1 setting), we need to create an internal processing handle to handle the selection itself. In this case, the internal processing handle to execute the selection (to process the -S|--select) has a parent handle (that is processing the actual non-reporting command). When this parent handle exists, we can't destroy the command log report in destroy_processing_handle as there's still the parent processing to finish. The parent processing may still generate logs which need to be reported in the command log report. If the command log report was destroyed prematurely together with destroying the internal processing handle for -S|--select, then any subsequent log request from processing the actual command (and hence an attermpt to access the command log report) ended up with a segfault. See also: https://bugzilla.redhat.com/show_bug.cgi?id=2175220
2023-03-07 16:45:06 +03:00

version 2.03.19 - 21st February 2023
post-release
2023-01-03 18:02:07 +03:00
====================================
WHATS_NEW: update
2023-02-10 22:51:46 +03:00
Configure supports --with-systemd-run executed from udev rules.
Enhancement for build with MuslC systemd and non-bash system shells (dash).
udev: don't reset SYSTEMD_READY in udev for PVs on MD and loop Since 67722b312390cdab29c076c912e14bd739c5c0f6, we have a new mechanism to run the autoactivation from udev. With this change, we also replaced the way the LVM autoactivation service is instantiatiated - instead of setting the SYSTEM_WANTS udev variable (which systemd read and then instantiated the service), we're now directly instantiating the transient 'lvm-activate-<vgname>' service by calling systemd-run. As such, we don't need to bother with setting the SYSTEMD_READY variable for foreign devices anymore (in this case, MD and loop devices on top of which there's a PV). Before, we set the SYSTEMD_READY variable to make sure that the SYSTEMD_WANTS is applied correctly - the service instantiation was edge-triggered by flipping the SYSTEMD_READY from 0 to 1 and at the same time having the SYSTEMD_WANTS variable set to the service name to instantiate. We're using systemd-run now so this condition does not apply anymore. Also, it was not completely correct to set SYSTEMD_READY for foreign devices because there might be cases where this could cause issues, see also https://github.com/lvmteam/lvm2/issues/94.
2023-02-01 16:33:25 +03:00
Do not reset SYSTEMD_READY variable in udev for PVs on MD and loop devices.
device_mapper: reactivate siblings for snapshot When activating origin and its thick snapshots, ensure the origin's LV udev processing is finished first and after this reactivate its snapshot so the udev can scan them afterwards. This should fix the problems for users using UUID of such device in their fstab and occasionaly mounted snapshot instead of origin LV.
2023-01-30 16:32:44 +03:00
Ensure udev is processing origin LV before its thick snapshots LVs.
vdo: fix and enhance vdo constain checking Enhance checking vdo constains so it also handles changes of active VDO LVs where only added difference is considered now. For this also the reported informational message about used memory was improved to only list consuming RAM blocks.
2023-01-15 23:27:37 +03:00
Fix and improve runtime memory size detection for VDO volumes.

Version 2.03.17 - 10th November 2022
====================================
Add new options (--fs, --fsmode) for FS handling when resizing LVs.
toollib: do not process just created historical LV When executing process_each_lv_in_vg, we process live LVs first and after that, we process any historical LVs. In case we have just removed an LV, which also means we have just made it "historical" and so it appears as fresh item in vg->historical_lvs list, we have to skip it when we get to processing historical LVs inside the same process_each_lv_in_vg call. The simplest approach here, without introducing another LV list, is to simply mark such historical LVs as "fresh" directly in struct historical_logical_volume when we have just removed the original LV and created the historical LV for it. Then, we just need to check the flag when processing historical LVs and skip it if it is "fresh". When we read historical LVs out of metadata, they are marked as "not fresh" and so they can be processed as usual. This was mainly an issue in conjuction with -S|--select use: # lvmconfig --type diff metadata { record_lvs_history=1 } (In this example, a thin pool with lvol1 thin LV and lvol2 and lvol3 snapshots.) # lvs -H vg -o name,pool_lv,full_ancestors,full_descendants LV Pool FAncestors FDescendants lvol1 pool lvol2,lvol3 lvol2 pool lvol1 lvol3 lvol3 pool lvol2,lvol1 pool # lvremove -S 'name=lvol2' Logical volume "lvol2" successfully removed. Historical logical volume "lvol2" successfully removed. ...here, the historical LV lvol2 should not have been removed because we have just removed its original non-historical lvol2 and the fresh historical lvol2 must not be included in the same processing spree.
2022-10-12 15:41:58 +03:00
Fix 'lvremove -S|--select LV' to not also remove its historical LV right away.
report: fix lv_active column type from STR to BIN Fix lv_active to be of BIN type instead of STR. This allows lv_active to follow the report/binary_values_as_numeric setting as well as --binary cmd line switch. Also, it makes it possible to use -S|--select with either textual or numeric representation of the value, like 'lvs -S active=active' but also 'lvs -S active=1'.
2022-09-06 15:40:06 +03:00
Fix lv_active field type to binary so --select and --binary applies properly.
mm: use mallinfo2 when available Switch to mallinfo2() from a deprecated mallinfo() glibc call since struct size members where to small for 64b CPUs.
2022-08-30 14:48:18 +03:00
Switch to use mallinfo2 and use it only with glibc.
args: add ARG_NONINTERACTIVE for cmds not supported in lvm shell Certain args can't be used in lvm shell ("interactive mode") because they are not supported there. Add ARG_NONINTERACTIVE flag to mark such args and error out if we're in interactive mode and at the same time we detect use of such argument. Currently, this is the case for --reportformat arg - we don't support changing the format per command in lvm shell. The whole shell is running under a reportformat chosen at shell's start.
2022-08-26 13:17:45 +03:00
Error out in lvm shell if using a cmd argument not supported in the shell.
shell: add pre-cmd log report object type and enable lastlog for it If we failed or logged anything before we actually execute given command in lvm shell, we couldn't report the log using lastlog command after. This patch adds specific 'pre-cmd' log report object type to identify such log messages and enables lastlog to report even this log.
2022-08-22 14:59:08 +03:00
Fix lvm shell's lastlog command to report previous pre-command failures.
vdo: extend volume and pool without flush When the volume size is extended, there is no need to flush IO operations (nothing can be targeting new space yet). VDO target is supported as target that can safely work with this condition. Such support is also needed, when extending VDOPOOL size while the pool is reaching its capacity - since this allows to continue working without reaching 'out-of-space' condition due to flushing of all in flight IO.
2022-08-19 15:48:01 +03:00
Extend VDO and VDOPOOL without flushing and locking fs.
lvmconfig: add --valuesonly option The new --valuesonly option causes the lvmconfig output to contain only values without keys for each config node. This is practical mainly in case where we use lvmconfig in scripts and we want to assign the value to a different custom key or simply output the value itself without the key. For example: # lvmconfig --type full activation/raid_fault_policy raid_fault_policy="warn" # lvmconfig --type full activation/raid_fault_policy --valuesonly "warn" # my_var=$(lvmconfig --type full activation/raid_fault_policy --valuesonly) # echo $my_var "warn"
2022-08-16 17:56:06 +03:00
Add --valuesonly option to lvmconfig to print only values without keys.
autoreconf: support newer archs Update to more recent version of configure script to support more new architecture types like RISCV64. Tools in use ATM: autoconf-2.71-3.fc37.noarch autoconf-archive-2022.02.11-3.fc37.noarch automake-1.16.5-9.fc37.noarch Resolves https://bugzilla.redhat.com/show_bug.cgi?id=2118243
2022-08-15 12:22:53 +03:00
Updates configure with recent autoconf tooling.
lvconvert: correct test support for vdo-pool
2022-08-11 12:44:58 +03:00
Fix lvconvert --test --type vdo-pool execution.
WHATS_NEW: update
2022-08-11 14:03:29 +03:00
Add json_std output format for more JSON standard compliant version of output.
Fix vdo_slab_size_mb value for converted VDO volume.

Version 2.03.16 - 18th May 2022
===============================
toollib: fix segfault when handling selection with historical LVs When processing historical LVs inside process_each_lv_in_vg for selection, we need to use dummy "_historical_lv" for select_match_lv. This is because a historical LV is not an actual LV, but only a tiny representation with subset of original properties that we recorded (name, uuid...). To use the same processing functions we use for full-fledged non-historical LVs, we need to use the prefilled "_historical_lv" structure which has all the other missing properties hard-coded.
2022-05-05 12:02:32 +03:00
Fix segfault when handling selection with historical LVs.
vdo: support --vdosettings Allow to use --vdosettings with lvcreate,lvconvert,lvchange. Support settings currenly only configurable via lvm.conf. With lvchange we require inactivate LV for changes to be applied. Settings block_map_era_length has supported alias block_map_period.
2022-04-13 16:09:08 +03:00
Add support --vdosettings with lvcreate, lvconvert, lvchange.
pre-release
2022-05-18 19:17:06 +03:00
Filtering multipath devices respects blacklist setting from multipath
configuration.
lvmdevices support for removing by device id using --deviceidtype and
--deldev.
Display writecache block size with lvs -o writecache_block_size.
Improve cachesettings description in man lvmcache.
thin: fix message processing on thin-pool extension When thin-pool had queued some delete message on extension operation such message has been 'lost' and thin-pool kernel metadata has been left with a thin volume that no longer existed for lvm2 metadata.
2022-03-30 15:16:11 +03:00
Fix lossing of delete message on thin-pool extension.

2022-02-07 20:00:54 +03:00
Version 2.03.15 - 07th February 2022
====================================
Remove service based autoactivation. global/event_activation = 0 is NOOP.
writecache: look for settings in lvm.conf Restore the lvm.conf cache_settings for writecache added by c6639056e0bb2fc5f072b2c0d6bb629ad17eee6e. Shorter method reduces and isolates the complexity of config trees.
2022-02-01 01:12:24 +03:00
Improve support for metadata profiles for --type writecache.
label: cache dm device list Since we check for present DM devices - cache result for futher use of checking presence of such device. lvm2 uses cache result for label scan, but also when it tries to activate or deactivate LV - however only simple target 'striped' is reasonably supported. Use disable_dm_devs to be able to control when lv_info() get cache or uncached results. TODO: support more type, however this is getting very complicated.
2021-12-15 13:45:22 +03:00
Use cache or active DM device when available with new kernels.
devicemapper: add dm_task_get_device_list New API extension (internal ATM) for getting a list of active DM device with extra features like i.e. uuid. To easily lookout for existing UUID in device list, there is: dm_device_list_find_by_uuid() Once the returned structure is no longer usable call: dm_device_list_destroy() Struct dm_active_device {} holds all the info, but is always allocated and destroyed within library. TODO: once it's stable, copy to libdm
2021-12-15 13:34:50 +03:00
Introduce function to utilize UUIDs from DM_DEVICE_LIST.
hash: raise hash table size With slightly bigger hash tables, there is considerable less hash collisions.
2021-12-17 18:36:36 +03:00
Increase some hash table size to better support large device sets.

Version 2.03.14 - 20th October 2021
===================================
WHATS_NEW: update
2021-10-20 12:08:36 +03:00
Device scanning is skipping directories on different filesystems.
archiving: refactor code to allocate less memory Do not store full path with each archived name reduces memory usage if the directory has thousands of entries and just add 'dir' path when needed. Also emit info print message to a user if the total size of archived files for a VG is more then 128MiB or 8192 files. TODO: Consider wheather adding a new 'lvm.conf archive{option}' to support trimming these wild archive sizes can make situation better. We already support retain_min && retain_days - but if user is generating too many and too large archives with minutes - maybe archiving should be disabled by a user - as it's not producing anything largely usable and just slows-down command ?? If we add 'retain_max & retain_max_size' the condition will go against each other and we need to chose priorities. mm
2021-10-01 17:19:53 +03:00
Print info message with too many or too large archived files.
metadata: optimize reading metadata copies in scan While being in lockless scanning phase, we can avoid reading and checking matching metadata copies if we already know them from other PV and just rely on matching metadata header information. These copies will be examined later during locked metadata read/write access. This patch may postpone discovering some read failures to locked phase.
2021-09-27 18:14:56 +03:00
Reduce metadata readings during scanning phase.
metadata: remember crc32 when writing vg metadata Preserve computed crc32 check from first written PV, just like we preserve generated metadata. Also there is no need to call crc32 twice on wrapping buffer with 2 calcs, result must be always the same as with single crc32 checking.
2021-09-27 12:41:03 +03:00
Optimize computation of crc32 check sum with multiple PVs.
cache: implement better revert path When cache creation fails on table reload path, implemen more advanced revert solution, that tries to restore state of LVM metadata into is look before actual caching started.
2021-09-12 18:44:38 +03:00
Enhance recover path on cache creation failure.
cache: filter out unsupported policy settings Loading invalid MQ/SMQ policy settings table line cause immediate rejection - to prevent such failure, automatically filter valid settins before it is being uploaded by lvm2. For invalid setting issue a warnning informing user how to remove them. This solution is used to keep running cached LVs that might had been created in the past with invalid settings that have been actually unused due to another code bug.
2021-09-12 18:41:53 +03:00
Filter out unsupported MQ/SMQ cache policy setting.
filters: fix memleak on mpath filter destroy Missing free() leaks filter structure.
2021-09-12 17:13:27 +03:00
Fix memleak in mpath filter.
vdo: read new sysfs path New versions of kvdo module exposes statistics at new location: /sys/block/dm-XXX/vdo/statistics/... Enhance lvm2 to access this location first. Also if the statistic info is missing - make it 'debug' level info, so it is not failing 'lvs' command.
2021-09-09 15:59:38 +03:00
Support newer location for VDO statistics.
WHATS_NEW: update
2021-10-20 12:08:36 +03:00
Add support for VDO async-unsafe write policy.
vdo: fixes Better identify VDO device with major:minor. Handle different LV name from originally converted origin LV. Improve --dry-run handling.
2021-08-31 21:52:26 +03:00
Improve lvm_import_vdo script.
Support VDO LV with lvcreate -ky.
Fix lvconvert for VDO LV bigger then 2T.
Create VDO LVs automatically without zeroing.
vdo: Rename vdoimport to lvm_import_vdo.
2021-08-26 17:53:33 +03:00

==================================
WHATS_NEW: update
2021-08-10 15:19:24 +03:00
Changes in udev support:
- obtain_device_list_from_udev defaults to 0.
- see devices/external_device_info_source,
devices/obtain_device_list_from_udev, and devices/multipath_wwids_file help
in lvm.conf
Fix devices file handling of loop with deleted backing file.
Fix devices file handling of scsi_debug WWIDs.
Fix many static analysis issues.
vgmerge: support option --poolmetadataspare
2021-07-23 17:32:35 +03:00
Support --poolmetadataspare with vgsplit and vgmerge.
thin: fix component detection of external origin When check active componet of thinLV with external origin, we need to check if the external origin isn't already active. For this however we need to use layered check for -real device.
2021-07-14 13:53:47 +03:00
Fix detection of active components of external origin volume.
vdo: add vdoimport support Add tool 'vdoimport' to support easy conversion of an existing VDO manager managed VDO volumes into lvm2 managed VDO LV. When physical converted volume is already a logical volume, conversion happens with the VG itself, just with validation for extent_size, so the virtually sized logical VDO volume size can be expressed in extents. Example of basic simple usage: vdoimport --name vg/vdolv /dev/mapper/vdophysicalvolume
2021-07-09 15:44:07 +03:00
Add vdoimport tool to support conversion of VDO volumes.
WHATS_NEW: update
2021-06-28 21:38:54 +03:00
Support configurable allocation/vdo_pool_header_size.
Fix handling of lvconvert --type vdo-pool --virtualsize.
archive: avoid abuse of internal flag Since archive is now postponned we use internal variable 'changed' to mark we need to commit new metadata.
2021-06-09 17:16:26 +03:00
Simplified handling of archive() and backup() internal calls.
WHATS_NEW: update
2021-08-10 15:19:24 +03:00

lvmcache: fix memory leak With commit 0b18c25d934564015402de33e15a267045ed1b8c there was introduced 'zalloc()' for allocation of outdates pvs, but no matching 'free()' is present. Switch to use cmd mempool instead of adding free() code into several places.

Lvreduce --yes support.
configure: support builds without versioning Not all libc (like musl, uclibc dietlibc) libraries support full symbol version resolution in runtime like glibc. Add support to not generate symbol versions when compiling against them. Additionally libdevmapper.so was broken when compiled against uclibc. Runtime linker loader caused calling dm_task_get_info_base() function recursively, leading to segmentation fault. Introduce --with-symvers=STYLE option, which allows to choose between gnu and disabled symbol versioning. By default gnu symbol versioning is used. __GNUC__ check is replaced now with GNU_SYMVER. Additionally ld version script is included only in case of gnu option, which slightly reduces output size. Providing --without-symvers to configure script when building against uclibc library fixes segmentation fault error described above, due to lack of several versions of the same symbol in libdevmapper.so library. Based on: https://patchwork.kernel.org/project/dm-devel/patch/20180831144817.31207-1-m.niestroj@grinn-global.com/ Suggested-by: Marcin Niestroj <m.niestroj@grinn-global.com>

Partial or degraded activation of writecache is not allowed.
WHATS_NEW: updates
2021-02-23 17:00:17 +03:00

WHATS_NEW: update
2020-10-24 02:40:55 +03:00
Dmeventd lvm plugin ignores higher reserved_stack lvm.conf values.
wipe_lv: use BLKZEROOUT when possible Since BLKZEROOUT ioctl should be supposedly fastest way how to clear block device start using this ioctl for zeroing a device. Commonly we do zero typically small portion of a device (8KiB) - however since we now also started to zero metadata devices, in the case of i.e. thin-pool metadata this can go upto ~16GiB and here the performance starts to be noticable.
2020-10-02 20:32:28 +03:00
Support using BLKZEROOUT for clearing devices.
wipe_lv: interruptible wiping Since we now block signals and wiping may take unexpectedly long time - support breaking command while wipe is in progress.
2020-10-02 20:31:05 +03:00
Support interruption when wipping LVs.
bcache: support interrupts when waiting on IO Since lvm2 normally block signals during protected phase where it does not want to be interrupted. Support interruptible processing when allowed in section between sigint_allow() ... sigint_restore()) and let the 'io_getenvents()' finish with EINTR.
2020-10-02 18:16:14 +03:00
Support interruption for bcache waiting.
bcache: fix busy loop with too many errors When bcache tries to write data to a faulty device, it may get out of caching blocks and then just busy-loops on a CPU - so this check protects this by checking if there is already max_io (~64) errored blocks.
2020-10-02 18:42:50 +03:00
Fix bcache when device has too many failing writes.
bcache: fix waiting problem for completed IO Call _wait_all() which does check whether there is still some pending IO before sleep. Otherwise it may happen our submitted IO operations have been already dispatched and this call then endlessly waits for IO which are all done. This can be reproduced when device returns quickly errors on write requests.
2020-10-02 18:18:12 +03:00
Fix bcache waiting for IO completion with failing disks.
configure: use our ordered list of python names Since it seems it's prefered now to use python3 in path name, prefer this name as first in the list.
2020-10-02 21:40:52 +03:00
Configure use own python path name order to prefer using python3.
configure: editline updates Update configure file.
2020-09-29 11:15:45 +03:00
Add configure --enable-editline support as an alternative to readline.
thin: enhance lvcreate error paths Improve error response and reporting, when creating thin snapshots. If the thin pool kernel metadata already have device with ID lvm2 tries to create, give more meanigful error message and also properly restore transaction id to the value known to thin-pool in this case. Before it's been possible to divert by one from kernel TID value, and lvm2 stacked delete message for such thin device.
2020-09-25 23:43:57 +03:00
Enhance reporting and error handling when creating thin volumes.
vgsplit: support for VDO volumes Enable support and ensure VDO always moves with VDOPOOL.
2020-09-24 21:49:18 +03:00
Enable vgsplit for VDO volumes.
vdo: enhance vdo pool extension When user tries to extend vdo pool - he needs to go always at least by 1 full VDO slab (defined as vdo_slab_size_mb). To avoid all trouble around find 'workable' size - lvm2 automatically increases the passed (or by --use-policies calculated) extension size (and informs a user about sometimes possibly large increase as slab size can go upto 32GiB) With VDO users need to always 'think-big' anyway and expect such operation to be in GiB domain range.
2020-09-23 00:25:58 +03:00
Lvextend of vdo pool volumes ensure at least 1 new VDO slab is added.
activation: use revert_lv on tree suspend failure When thetable reload fails during suspend() - we were only calling plain resume() - and this will reload only those devices, which were left suspend, but will not try to restore metadata state according to lvm2 reverted metadata. So if we were reloading device tree - we have restored only top-level LV and rest of reverted device manipulation were left alone and possibly mismatched what is in committed metadata. FIXME: There are several cases were such revert will likely not work properly anyway as some operation are currenly handled in single commit, while they need multiple commits, but it's step towards better correctness. At least we catch there errors now earlier.
2020-09-22 14:35:27 +03:00
Use revert_lv() on reload error path after vg_revert().
configure: enable integrity by default
2020-09-16 23:14:51 +03:00
Configure --with-integrity enabled.
locking: restore blocking signal for VG_GLOBAL lck During removal of a lot of locking code the signal blocking got lost and signal processing got broken leading to unpredictable behavior of i.e. activation code the can get interrupted in the middle of DM table processing. lvm2 code always expects signals are blocked while lock is held unless it is explictelly placed into section of: sigint_allow();....;sigint_restore(); For checking catched interrupt there is sigint_catched();
2020-09-13 22:10:17 +03:00
Restore lost signal blocking while VG lock is held.
alloc: improve estimation of sufficient_pes_free Metadata size was calculated correctly only for raids. Fixes problem for crash during lvcreate when thin-pool was created on a VG where remaining free space had the size to only fit a single metadata LV and not also its _pmspare. Lvcreate crashed with this assert message: lvcreate: metadata/pv_map.c:198: consume_pv_area: Assertion `to_go <= pva->count' failed. Aborted (core dumped) TODO: there is probably to large overload of several alloc_handle variables.

2020-09-11 21:57:20 +03:00
Improve estimation of needed extents when creating thin-pool.
thin: compensate metadata size by extra percent When using --use-policy for automatic extension of thin-pool, the extension of thin-pool's metadata itself can actually take some extra space. Since I'm not aware of exact compensation formula, add just 1% extra to calculated amount and hope it fits. Wanted target is to always have usable thin-pool that fits bellow pool_metadata_min_threshold().
2020-09-11 14:31:55 +03:00
Use extra 1% when resizing thin-pool metadata LV with --use-policy.
lvextend: improve percentage estimation Correcting rounding rules for percentage evaluation. Validate supported range of percentage. (although ranges are already validated earlier on code path)
2020-09-10 23:38:34 +03:00
Enhance --use-policy percentage rounding.
configure: compile with vdo and writecache by default Enable compilation of vdo and writecache support as internaly supported segment types by default. For disabling use: --with-vdo=none --with-writcache=none
2020-09-09 16:56:06 +03:00
Configure --with-vdo and --with-writecache as internal segments.

Integrity volumes defaults to journal mode.
gcc: zero-sized array to fexlible array C99 Switch remaining zero sized struct to flexible arrays to be C99 complient. These simple rules should apply: - The incomplete array type must be the last element within the structure. - There cannot be an array of structures that contain a flexible array member. - Structures that contain a flexible array member cannot be used as a member of another structure. - The structure must contain at least one named member in addition to the flexible array member. Although some of the code pieces should be still improved.
2020-08-28 20:15:01 +03:00
Switch code base to use flexible array syntax.

Converting RAID1 volume to one with same number of legs now succeeds with a
warning.
lvconvert: preset raid1 in case of striped conversions Fixed invoking "lvconvert -m+1 $StripedLV" to cause errors (preset raid conversion implied by '-m'). Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1781406
2020-07-09 19:51:33 +03:00
Fix conversion to raid from striped lagging type.
lvconvert: fix conversion to 'mirrored' mirror log with larger regionsize merge.c:_check_lv_segment() was checking regionsize vs. mirrored LV size on any 'mirror/raid1/raid10' segment type including type 'mirrored' mirror logs. Avoid the check only for 'mirrored' mirror logs to allow conversion from log type 'disk' with regionsize > mirror log SubLV size. As we disabled support for 'mirrored' mirror logs with commit e82303fd6abc3ae43168f8032806c7c17d181a3e which still conditionally allows to enable it via global/support_mirrored_mirror_logs=1, patch is mandatory for all distributions. Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1712983
2020-07-09 15:09:46 +03:00
Fix conversion to 'mirrored' mirror log with larger regionsize.
pool: zero metadata To avoid polution of metadata with some 'garbage' content or eventualy some leak of stale data in case user want to upload metadata somewhere, ensure upon allocation the metadata device is fully zeroed. Behaviour may slow down allocation of thin-pool or cache-pool a bit so the old behaviour can be restored with lvm.conf setting: allocation/zero_metadata=0 TODO: add zeroing for extension of metadata volume.
2020-06-24 13:11:21 +03:00
Zero pool metadata on allocation (disable with allocation/zero_metadata=0).
wipe_lv: make error a fatal event Failure in wiping/zeroing stop the command. If user wants to avoid command abortion he should use -Zn or -Wn to avoid wiping. Note: there is no easy way to distinguish which kind of failure has happend - so it's safe to not proceed any futher.
2020-06-23 14:56:15 +03:00
Failure in zeroing or wiping will fail command (bypass with -Zn, -Wn).
post-release
2020-08-09 17:16:39 +03:00

cachevol: stop dm errors with uncaching cache with cachevol Fix the anoying kernel message reported: device-mapper: cache: 253:2: metadata operation 'dm_cache_commit' failed: error = -5 which has been reported while cachevol has been removed. Happened via confusing variable - so switch the variable to commonly user '_size' which presents a value in sector units and avoid 'scaling' this as extent length by vg extent size when placing 'error' target on removal path. Patch shouldn't have impact on actual users data, since at this moment of removal all date should have been already flushed to origin device. m

====================================
Subcommand in vgck for repairing headers and metadata.
lvcreate: ensure striped raid region size is at least stripe size The kernel MD runtime requires region size to be larger than stripe size on striped raid layouts, thus the dm-raid target's constructor rejects such request. This causes e.g. an 'lvcreate --type raid10 -i3 -I4096 -R2048 -n lv vg' to fail. Avoid failing late in the kernel by enforcing region size to be larger or equal to stripe size.

Version 2.03.06 - 23rd October 2019
===================================
cache: use _cpool for used cache-pools When LV gets cached and uses cache-pool - such cache-pool will now get _cpool suffix automatically. Thus 'Pool' column for cached LV will now show either _cvol or _cpool LV.
2019-10-21 13:03:19 +03:00
Add _cpool suffix to cache-pool LV name when used by caching LV.
cachevol: use CVOL UUID for cdata and cmeta layered devices Since code is using -cdata and -cmeta UUID suffixes, it does not need any new 'extra' ID to be generated and stored in metadata. Since introduce of new 'segtype' cache+CACHE_USES_CACHEVOL we can safely assume 'new' cache with cachevol will now be created without extra metadata_id and data_id in metadata. For backward compatibility, code still reads them in case older version of metadata have them - so it still should be able to activate such volumes. Bonus is lowered size of lv structure used to store info about LV (noticable with big volume groups).
2019-10-16 17:05:51 +03:00
No longer store extra UUID for cmeta and cdata cachevol layer.
cachevol: improve manipulation with dm tree Enhance activation of cached devices using cachevol. Correctly instatiace cachevol -cdata & -cmeta devices with '-' in name (as they are only layered devices). Code is also a bit more compacted (although still not ideal, as the usage of extra UUIDs stored in metadata is troublesome and will be repaired later). NOTE: this patch my brink potentially minor incompatiblity for 'runtime' upgrade
2019-10-14 11:31:38 +03:00
Enhance activation of cache devices with cachevols.
cachevol: put _cvol as protected suffix. This revert "drop cvol dm uuid suffix for cachevol LVs" commit 5191057d9df3e5b92db3f80c412b99aea1074358. Start using -cvol for DM UUID.
2019-10-07 15:58:26 +03:00
Add _cvol in list of protected suffixes and start use it with DM UUID.
cachevol: rename converted LV to _cvol When converting existing public LV to internally used 'CacheVol' LV - rename LV to LV_cvol. When splitting CacheVol, remove _cvol suffix.
2019-10-13 00:37:17 +03:00
Rename LV converted to cachevol to use _cvol suffix.
cachevol: wipe 'normal' device For wiping we activate and clear 'regular' devices, since in case of whole process interuption (i.e. kill -9) we leave metadata & DM table and workable state all the time.
2019-10-11 16:27:41 +03:00
Use normal LVs for wiping of cachevols.
cache: reload only when switched to cleaner policy Reload cache target only when lvm2 reload table with cache with clearer policy.
2019-10-12 12:12:11 +03:00
Reload cleanered cache DM only with cleaner policy.
pre-release
2019-10-23 10:46:23 +03:00
Fix cmd return when zeroing of cachevol fails.
WHATS_NEW: update
2019-10-04 18:30:52 +03:00
Extend lvs to show all VDO properties.
Preserve VDO write policy with vdopool.
Increase default vdo bio threads to 4.
Continue report when cache_status fails.
dm: fix compilation of dmsetup Fix: 889c88e9dab33195efc4dc0400a4b0aaa3383948 Use correct enum DM_DEVICE_GET_TARGET_VERSION.
2019-10-21 17:31:53 +03:00
Add support for DM_DEVICE_GET_TARGET_VERSION into device_mapper.
WHATS_NEW: update
2019-10-04 18:30:52 +03:00
Fix cmirrord usage of header files from device_mapper subdir.
vdo: enhance activation with layer -vpool Enhance 'activation' experience for VDO pool to more closely match what happens for thin-pools where we do use a 'fake' LV to keep pool running even when no thinLVs are active. This gives user a choice whether he want to keep thin-pool running (wihout possibly lenghty activation/deactivation process) As we do plan to support multple VDO LVs to be mapped into a single VDO, we want to give user same experience and 'use-patter' as with thin-pools. This patch gives option to activate VDO pool only without activating VDO LV. Also due to 'fake' layering LV we can protect usage of VDO pool from command like 'mkfs' which do require exlusive access to the volume, which is no longer possible. Note: VDO pool contains 1024 initial sectors as 'empty' header - such header is also exposed in layered LV (as read-only LV). For blkid we are indentified as LV with UUID suffix - thus private DM device of lvm2 - so we do not need to store any extra info in this header space (aka zero is good enough).
2019-09-14 02:13:33 +03:00
Allow standalone activation of VDO pool just like for thin-pools.
thin: activate layer pool aas read-only LV When lvm2 is activating layered pool LV (to basically keep pool opened, the other function used to be 'locking' be in sync with DM table) use this LV in read-only mode - this prevents 'write' access into data volume content of thin-pool. Note: since EMPTY/unused thin-pool is created as 'public LV' for generic use by any user who i.e. wish to maintain thin-pool and thins himself. At this moment, thin-pool appears as writable LV. As soon as the 1st. thinLV is created, layer volume will appear is 'read-only' LV from this moment.
2019-09-14 02:08:14 +03:00
Activate thin-pool layered volume as 'read-only' device.
devices: crypto skip Devices with UUID signature CRYPT-SUBDEV are internal crypto devices.
2019-09-13 14:22:07 +03:00
Ignore crypto devices with UUID signature CRYPT-SUBDEV.
lvconvert: improve validation thin and cache pool conversion Limit convertible LVs to thin-pool and cache-pools. Also fix return code on interal error path to return ECMD_FAILED.
2019-09-06 19:09:40 +03:00
Enhance validation for thin and cache pool conversion and swapping.
cache: improve vgremove loop Support internal removal of 'cache origin' volume - which we do not normally expose to a user - however internal processing loops may hit this condition (depending on order of list LVs). So when this operation is internally requested - we automatically try to remove it's 'holding' LV (cache LV) - which will also remove the origin.
2019-08-26 14:28:00 +03:00
Improve internal removal of cached devices.
activation: add synchronization point Resuming of 'error' table entry followed with it's dirrect removal is now troublesame with latest udev as it may skip processing of udev rules for already 'dropped' device nodes. As we cannot 'synchronize' with udev while we know we have devices in suspended state - rework 'cleanup' so it collects nodes for removal into pending_delete list and process the list with synchronization once we are without any suspended nodes.
2019-08-17 00:49:59 +03:00
Synchronize with udev when dropping snapshot.
pvmove: add missing synchronization Between 'resume' and 'remove' we need to wait for udev to synchronize, otherwise udev may 'skip' resume event processing if the udev node is already gone.
2019-08-20 13:23:08 +03:00
Add missing device synchronization point before removing pvmove node.
pvmove: correcting read_ahead setting When pvmove is finished, we do a tricky operation since we try to resume multiple different device that were all joined into 1 big tree. Currently we use the infromation from existing live DM table, where we can get list of all holders of pvmove device. We look for these nodes (by uuid) in new metadata, and we do now a full regular device add into dm tree structure. All devices should be already PRELOAD with correct table before entering suspend state, however for correctly working readahead we need to put correct info also into RESUME tree. Since table are preloaded, the same table is skip and resume, but correct read ahead is now set.
2019-08-20 13:30:25 +03:00
Correctly set read_ahead for LVs when pvmove is finished.
udev: remove unsupported OPTIONS+="event_timeout" rule The OPTIONS+="event_timeout" is Unsupported since systemd/udev version 216, that is ~5 years ago. Since systemd/udev version 243, there's a new message printed if unsupported OPTIONS value is used: Invalid value for OPTIONS key, ignoring: 'event_timeout=180' Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1740666
2019-08-13 16:18:30 +03:00
Remove unsupported OPTIONS+="event_timeout" udev rule from 11-dm-lvm.rules.
WHATS_NEW: vgcreate/vgextend logical block size

================================
cache: support no_discard_passdown Recent kernel version from kernel commit: de7180ff908b2bc0342e832dbdaa9a5f1ecaa33a started to report in cache status line new flag: no_discard_passdown Whenever lvm spots unknown status it reports: Unknown feature in status: So add reconginzing this feature flag and also report this with 'lvs -o+kernel_discards' When no_discard_passdown is found in status 'nopassdown' gets reported for this field (roughly matching what we report for thin-pools).
2019-06-05 15:31:34 +03:00
Report no_discard_passdown for cache LVs with lvs -o+kernel_discards.
WHATS_NEW: pvck --dump
2019-05-23 19:50:16 +03:00
Add pvck --dump option to extract metadata.
libdaemon: use pselect to avoid condition checking race To avoid tiny race on checking arrival of signal and entering select (that can latter remain stuck as signal was already delivered) switch to use pselect(). If it would needed, we can eventually add extra code for older systems without pselect(), but there are probably no such ancient systems in use.
2019-04-10 13:50:53 +03:00
Fix signal delivery checking race in libdaemon (lvmetad).
systemd: add missing Before=shutdown.target to LVM2 services to fix shutdown ordering We already used Conflicts=shutdown target to stop LVM2 services on shutdown. But we still missed the ordering - the shutdown.target should be reached only after all the services are really stopped. Reported here: https://github.com/lvmteam/lvm2/issues/17
2019-04-09 13:10:17 +03:00
Add missing Before=shutdown.target to LVM2 services to fix shutdown ordering.
WHATS_NEW: add several recent changes
2019-04-08 18:56:43 +03:00
Skip autoactivation for a PV when PV size does not match device size.
Remove first-pvscan-initialization which should no longer be needed.
Add remote refresh through lvmlockd/dlm for shared LVs after lvextend.
Ignore foreign and shared PVs for pvscan online files.
Add config setting to control fields in debug file and verbose output.
Add command[pid] and timestamp to debug file and verbose output.
thin: fix maintenance of _pmspare When metadata grows lvm2 may need to extend also _pmspare volume.
2019-04-03 14:02:50 +03:00
Fix missing growth of _pmsmare volume when extending _tmeta volume.
thin: resize metadata with data When data are growing, adapt also size of metadata. As we get way too many reports from users doing huge growths of data portion while keep metadata small and avoiding using monitoring. So to enhance the user-experience in case user requests grown of thin-pool (without passing PV list for growth) - lvm2 will automaticaly grown also the metadata part of thin-pool (if possible).
2019-04-03 14:01:06 +03:00
Automatically grow thin metadata, when thin data gets too big.
activation: synchronize before removing devices Udev is running udev-rule action upon 'resume'. However lvm2 in special case is doing replacement of 'soon-to-be-removed' device with 'error' target for resuming and then follows actual removal - the sequence is usually quick, so when udev start action - it can result in 'strange' error message in kernel log like: Process '/usr/sbin/dmsetup info -j 253 -m 17 -c --nameprefixes --noheadings --rows -o name,uuid,suspended' failed with exit code 1. To avoid this - we need to ensure there is synchronization wait for udev between 'resume' and 'remove' part of this process. However existing code put strict requirement to avoid synchronizing with udev inside critical section - but this originally came from requirement to not do anything special while there could be devices in suspend-state. Now we are able to see differnce between critical section with or without suspended devices. For udev synchronization only suspended devices are prohibited to be there - so slightly relax condition and allow calling and using 'fs_sync()' even inside critical section - but there must not be any suspended device.
2019-02-06 14:37:47 +03:00
Add synchronization with udev before removing cached devices.
vdo: enable caching for vdopool LV and vdo LV Allow using caching with VDO. User can either cache a single vdopool or a vdo LV - difference when the caching is put-in depends on a use-case and it's upto user to decide which kind of speed is expected.
2019-01-24 16:12:26 +03:00
Add support for caching VDO LVs and VDOPOOL LVs.
cache: support vgsplit Enable vgsplit to work with VG containing cached LVs.
2019-02-01 23:29:22 +03:00
Add support for vgsplit with cached devices.
filter: enhance mpath detection Internal detection of SCSI device being in-use by DM mpath has been performed several times for each component device - this could be eventually racy - so instead when we do remember 1st. checked result for device being mpath and use it consistenly over the filter runtime.
2019-03-13 15:02:09 +03:00
Query mpath device only once per command for its state.
dev_manager: add dev_manager_remove_dm_major_minor Move DM usage into dev_manager.c source file. Also convert STATUS to INFO ioctl - as that's enough to obtain UUID - this also avoid issuing unwanted flush on checked DM device for being mpath.
2019-03-13 14:59:59 +03:00
Use device INFO instead of STATUS when checking for mpath device uuid.
WHATS_NEW: io_memory_size
2019-03-04 21:22:49 +03:00
Change default io_memory_size from 4 to 8 MiB.
Add config setting io_memory_size to set bcache size.
WHATS_NEW: concurrent pvscan autoactivation
2019-02-22 00:31:23 +03:00
Fix pvscan autoactivation for concurrent pvscans.
WHATS_NEW: scan_lvs default change
2019-02-20 23:04:49 +03:00
Change scan_lvs default to 0 so LVs are not scanned for PVs.
thin: select chunk size as power of 2 Whenever thin-pool chunk size is unspecified and left for lvm calculation try to select the size as nearest highest power-of-2 instead of just being a multiple of 64KiB.
2019-01-28 21:50:41 +03:00
Thin-pool selects power-of-2 chunk size by default.
cache: select chunk size as power of 2 When cache chunk size is not configured, and left for lvm deduction, select the value which is power-of-2.
2019-01-28 22:08:49 +03:00
Cache selects power-of-2 chunk size by default.
vdo: allow resize of VDO and VDO pool volumes Now with newer VDO kvdo target we can start to use standard mechanism to enable resize of VDO volumes. VDO pool can be grown. Virtual volume grows on top of VDO pool when is not big enough. Reduced VDOLV is calling discard for reduced areas - this can take long time! TODO: implement some pollable mechanism for out-of-lock TRIM.
2019-01-10 20:00:06 +03:00
Support reszing for VDOPoolLV and VDOLV.
lv_manip: better work with PERCENT_VG modifier When using 'lvcreate -l100%VG' and there is big disproportion between real available space and requested setting - automatically fallback to 100%FREE. Difference can be seen when VG is big and already most space was allocated, so the requestion 100%VG can end (and by spec for % modifier it's correct) as LV with size of 1%VG. Usually this is not a big problem - buit in some cases - like cache-pool allocation, this can result a big difference for chunksize selection. With this patch it's more closely match common-sense logic without the need of reitteration of too big changes in lvm2 core ATM. TODO: in the future there should be allocator solving all allocations in a single call.
2019-01-19 00:27:02 +03:00
Improve -lXXX%VG modifier which improves cache segment estimation.
dm: ensure migration_threshold is big enough When using caches with BIG pool size (>TB) there is required to use relatively huge chunk size. Once the chunksize has got over 1MiB - kernel cache target stopped writing such chunks back on this if the migration_threshold remained on default 1MiB (2048 sectors) size. This patch ensure, DM layer will not let pass table line which has not big enough migration threshold that can let pass at least 8 chunks (independently of lvm2 metadata).
2019-01-20 13:45:10 +03:00
Ensure migration_threshold for cache is at least 8 chunks.
man: missed --zero option for thin-pool creation During man page rewrite this info got lost and remained only for lvconvert. So restore it back for lvcreate.
2019-01-19 00:38:34 +03:00
Restore missing man info lvcreate --zero for thin-pools.
vdo: fix archived metadata comment lvm uses 'minimum_io_size' name to exactly match VDO naming here, however in all common cases _size is using 'sector/512b' unit. But in this case the value is in bytes and can have only 2 values: either 512 or 4096. It's probably not worth to rename it internaly, so we can just drop comment - instead of using 1 or 8. Thought let's think about it....
2019-01-14 18:21:02 +03:00
Drop misleadning comment for metadata minimum_io_size for VDO segment.
WHATS_NEW: device hints
2019-01-15 19:33:25 +03:00
Add device hints to reduce scanning.
generators: avoid contacting syslog with generators The systemd generators are executed very early during the switch from initramfs to system partition and the syslog is not yet fully operational - it may cause blocking, if some debug logging is enabled at the same time in /etc/lvm/lvm.conf log{} section. To avoid timeouting and killing this generator - rather enhance lvm code to suppress any syslog communication when LVM_SUPPRESS_SYSLOG envvar is set. Use of this envvar is needed since the parsing of i.e. cmdline options that could eventually override lvm.conf setting happens in this case way too late and number of lines could have been already streamed to syslog.
2019-01-07 17:48:39 +03:00
Introduce LVM_SUPPRESS_SYSLOG to suppress syslog usage by generator.
scripts: lvm2-activation-generator fix lvmconfig call Fix a scenario where global/event_activation setting is not found. In this case we need to take default value just like lvm tools do when executed. So use "lvmconfig --type full". Also, if we fail to execute lvmconfig for whatever reason, fallback to generating the activation units as failsafe action. Reported by: Bastian Blank <waldi debian org>
2019-01-04 13:11:13 +03:00
Fix generator quering lvmconfig unpresent config option.
bcache: fix memory leak on error path Coverity noticed missing free of io struct on error path.
2018-12-21 23:01:18 +03:00
Fix memleak on bcache error path code.
dmeventd: unlock lvm2 lock on error path New code missed to unlock locked lvm2 on error path when command is not configured.
2018-12-21 23:29:05 +03:00
Fix missing unlock on lvm2 dmeventd plugin error path initialization.
lvmpolld: improve makefile deps Add correct build dependencies on internal libraries.
2018-12-21 13:24:00 +03:00
Improve Makefile dependency tracking.
lib: move towards v2 version of VDO format Drop very old original format of VDO target and focus on V2 version. So some variables were renamed or replaced. There is no compatibility preserved (with assumption so far this is experimental feature and there is no real user). Note - version currently VDO calls this version 6.2.
2018-12-20 15:17:30 +03:00
Move VDO support towards V2 target (6.2) support.

Version 2.03.02 - 18th December 2018
====================================
lvmanip: uninitialized members in struct pv_list (#10) Scenario: Given an existed LV `lvol0`, I want to create another LV on the PVs used by `lvol0`. I use `build_parallel_areas_from_lv()` to obtain the `pv_list` of each segments. However, the returned `pv_list` is not properly initialized, which causes segfault in subsequent operations.
2018-12-14 12:51:51 +03:00
Fix missing proper initialization of pv_list struct when adding pv.

Version 2.03.00 - 10th October 2018
===================================
dmeventd: lvm2 plugin uses envvar registry Thin plugin started to use configuble setting to allow to configure usage of external scripts - however to read this value it needed to execute internal command as dmeventd itself has no access to lvm.conf and the API for dmeventd plugin has been kept stable. The call of command itself was not normally 'a big issue' until users started to use higher number of monitored LVs and execution of command got stuck because other monitored resource already started to execute some other lvm2 command and become blocked waiting on VG lock. This scenario revealed necesity to somehow avoid calling lvm2 command during resource registration - but this requires bigger changes - so meanwhile this patch tries to minimize the possibility to hit this race by obtaining any configurable setting just once - such patch is small and covers majority of problem - yet better solution needs to be introduced likely with bigger rework of dmeventd. TODO: avoid blocking registration of resource with execution of lvm2 commands since those can get stuck waiting on mutexes.
2018-08-27 11:18:26 +03:00
Add hot fix to avoiding locking collision when monitoring thin-pools.
lvconvert: allow raid4 -> linear conversion request Allow "lvconvert --type linear RaidLV" on a raid4 LV providing convenient interim steps to convert to linear. Add respective new test lvconvert-raid-takeover-raid4_to_linear.sh and lvconvert-raid-takeover-linear_to_raid4.sh for linear to raid4 once on it.
2018-09-10 19:36:52 +03:00
Allow raid4 -> linear conversion request.
lvconvert: fix interim segtype regression on raid6 conversions When converting from striped/raid0/raid0_meta to raid6 with > 2 stripes, allow possible direct conversion (to raid6_n_6). In case of 2 stripes, first convert to raid5_n to restripe to at least 3 data stripes (the raid6 minimum in lvm2) in a second conversion before finally converting to raid6_n_6. As before, raid6_n_6 then can be converted to any other raid6 layout. Enhance lvconvert-raid-takeover.sh to test the 2 stripes conversions to raid6. Resolves: rhbz1624038
2018-09-07 14:48:13 +03:00
Fix lvconvert striped/raid0/raid0_meta -> raid6 regression.
scripts: lvm2-activation-generator: add prefix for all kmsg messages Add "lvm2-activation-generator: " prefix for all kmsg messages written by lvm2-activation-generator so we can identify the message in global system log.
2018-08-30 13:46:41 +03:00
Add 'lvm2-activation-generator:' prefix for kmsg messages logged by generator.
scripts: add After=rbdmap.service to {lvm2-activation-net,blk-availability}.service We need to have Ceph RBD devices mapped first before use in a stack where LVM is on top so make sure rbdmap.service is called before generated lvm2-activation-net.service. On shutdown, we need to stop blk-availability first before we stop the rbdmap.service. Resolves: rhbz1623479
2018-08-30 13:35:58 +03:00
Add After=rbdmap.service to {lvm2-activation-net,blk-availability}.service.
bcache: reduce MAX_IO to 256 This is the number of concurrent async io requests that the scan layer will submit to the bcache layer. There will be an open fd for each of these, so it is best to keep this well below the default limit for max open files (1024), otherwise lvm may get EMFILE from open(2) when there are around 1024 devices to scan on the system.
2018-08-24 22:46:51 +03:00
Reduce max concurrent aios to avoid EMFILE with many devices.
lvconvert: fix conversion attempts to linear "lvconvert --type linear RaidLV" on striped and raid4/5/6/10 have to provide the convenient interim layouts. Fix involves a cleanup to the convenience type function. As a result of testing, add missing sync waits to lvconvert-raid-reshape-linear_to_raid6-single-type.sh. Resolves: rhbz1447809
2018-08-22 17:39:36 +03:00
Fix lvconvert conversion attempts to linear.
lvconvert: fix regression preventing direct striped conversion Conversion to striped from raid0/raid0_meta is directly possible. Fix a regression setting superfluous interim raid5_n conversion type introduced by commit bd7cdd0b09ba123b064937fddde08daacbed7dab. Add new test script lvconvert-raid0-striped.sh. Resolves: rhbz1608067
2018-08-21 18:12:33 +03:00
Fix lvconvert raid0/raid0_meta -> striped regression.
mirror: fix splitmirrors for mirror type With improved mirror activation code --splitmirror issue poppedup since there was missing proper preload code and deactivation for splitted mirror leg.
2018-08-07 11:34:17 +03:00
Fix lvconvert --splitmirror for mirror type (2.02.178).
cache: drop metadata_format validation Allow to use any combination of cache metadata format for policy.
2018-08-07 11:33:19 +03:00
Do not pair cache policy and cache metadata format.
lvconvert: reject conversions on raid1 split trackchanges LVs Prohibit, because the tracking can't continue and further conversions may fail with bogus error messages. Resolves: rhbz1579072

lvconvert: reject conversions on raid1 LVs with split tracked SubLVs
lvconvert: reject conversions on raid1 split trackchanges SubLVs Prohibit conversions of raid1 split trackchanges SubLVs because they will fail to get merged back into the RaidLV. Resolves: rhbz1579438

lvconvert: reject conversions on raid1 split tracked SubLVs
lvcreate: vdo support Supports basic: 'lvcreate --vdo -LXXXG -VYYYG vg/vdoname -n lvname' Allows to create basic VDO pool volume and virtual VDO volume.
2018-06-29 14:16:08 +03:00
Add basic creation support for VDO target.
build: libdm preload dir is no longer needed Since we do not build lvm code with libdm, drop preload.
2018-07-03 12:12:04 +03:00
Never send any discard ioctl with test mode.
Fix thin-pool alloc which needs same PV for data and metadata.
memlock: extend exception list Amound of linked libraries grows. Most of them we don't need to lock in, since we are not using them in locked section, so skip locking them in memory.
2018-06-30 12:05:14 +03:00
Extend list of non-memlocked areas with newly linked libs.
vcfgrestore: add prompt with active volumes Add check for active device with names matching restored VG. When such devices are present in dm table, prompt user, if he wish to continue.
2018-06-22 19:45:48 +03:00
Enhance vgcfgrestore to check for active LVs in restored VG.
build: support --disable-silent-rules Add support for standardized option for have verbose builds. Useful for distro builds where more details can be useful.
2018-06-23 00:30:42 +03:00
Configure supports --disable-silent-rules for verbose builds.
snapshot: improve checking of merging snapshot Add runtime detection for 'lvs -o+seg_monitor' and 'vgchange --monitor'. This fix should avoid unnecessary timeout on systemd shutdown.
2018-06-11 23:19:20 +03:00
Fix unmonitoring of merging snapshots.
cache: cleaner policy also uses fmt2 Format 2 is also with cleaner policy.
2018-06-08 13:37:07 +03:00
Cache can uses metadata format 2 with cleaner policy.
pvresize: add missing return Log error path missed return 0. Also fix some unneded bactraces (since log_error already shows position).
2018-06-05 22:21:26 +03:00
Fix check if resized PV can also fit metadata area.
pvmove: improve lvs When pvmoving LV - the target for LV is a mirror so the validation that checked the type is matching was incorrect. While we need a more generic enhancment of LVS output for pvmoved LVs, for now at least stop showing internal errors and 'X' symbols in attrs.
2018-06-04 12:05:28 +03:00
Avoid showing internal error in lvs output or pvmoved LVs.

mirror: validate region_size for mirrors Check for region size properties of mirror segments.
2018-04-19 18:38:04 +03:00
Extend validation of region_size for mirror segment.
mirror: properly reload table for log init Since mirror can be stacked, we need to properly reload whole table stack, otherwice we may mishandle devices in dm table.
2018-03-30 00:26:22 +03:00
Reload whole device stack when reinitilizing mirror log.
Mirrors without monitoring are WARNING and not blocking on error.
mirror: fix region_size for clustered VG When adjusting region size for clustered VG it always needs to fit 2 full bitset into 1MB due to old limits of CPG. This is relatively big amount of bits, but we have still limitation for region size to fit into 32bits (0x8000000). So for too big mirrors this operation needs to fail - so whenever function returns now 0, it means we can't find matching region_size. Since return 0 is now 'error' we need to also pass proper region_size when creating pvmove mirror.
2018-04-20 11:07:42 +03:00
Detect too big region_size with clustered mirrors.
mirror: fix calcs for maximal region_size Since extent_size is no longer power_of_2 this max region size evalution was rather producing random bitsize as a combination of lowest bit from number of extents and extent size itself. Correct calculation to use whole LV size and pick biggest possible power of 2 value smaller then UINT32_MAX.
2018-04-20 11:03:26 +03:00
Fix evaluation of maximal region size for mirror log.
mirror: improve mirror log size estimation Drop mirrored mirror log limitation that applies only in very limited use-case and actually mirrored mirror log is deprecated anyway. So 'disk' mirror log is selecting the correct minimal size, and bigger size is only enforced with real mirrored mirror log. Also for mirrored mirror log we let use 'smalled' region size if needed so if user uses 1G region size, we still keep small mirror log with much smaller region size in this case when needed. Also mirror log extent calculation is now properly detecting error with too big mirrors where previosly trimmed uint32_t was applies unintentionally.
2018-04-20 11:12:25 +03:00
Enhance mirror log size estimation and use smaller size when possible.
mirror: fix 32bit size calculation On 32bit arch size_t remains 4-byte wide - so size can't get correct result for multiplication of 32bit numbers.
2018-04-19 13:29:42 +03:00
Fix incorrect mirror log size calculation on 32bit arch.
WHATS_NEW: typo
2018-05-22 11:46:59 +03:00
Enhance preloading tree creating.
lvconvert: drop limitation for converting lv Fixing regresion on argument acceptance where any lv can be passed with paramaterless lvconvert which is meant to figure out needed operation - i.e. wait for mirror synchronization. User has no other 'effective' method to wait for mirror getting in-sync.
2018-04-18 13:57:17 +03:00
Fix regression on acceptance of any LV on lvconvert.
thin: restore usability of thin for external origin With command definition it's been lost support for thin LV being an external origin for another thinLV.
2018-03-29 19:55:09 +03:00
Restore usability of thin LV to be again external origin for another thin.
udev: keep systemd vars on change event in 69-dm-lvm-metad.rules for systemd reload The current logic that avoids setting SYSTEMD_ALIAS and SYSTEMD_WANTS on "change" events is flawed in the default "systemd background job" configuration. For systemd, it's important that device properties don't change spuriously. If an "add" event starts lvm2-pvscan@.service for a device, and a "change" event follows, removing SYSTEMD_ALIAS and SYSTEMD_WANTS from the udev db, information about unit dependencies between the device and the pvscan service can be lost in systemd, in particular if the daemon configuration is reloaded. Steps to reproduce problem: - create a device with an LVM PV - remove device - add device (generates "add" and "change" uevents for the device) (at this point SYSTEMD_ALIAS and SYSTEMD_WANTS are clear in udev db) - systemctl daemon-reload (systemd reloads udev db) - vgchange -a n - remove device => the lvm2-pvscan@.service for the device is still active although the device is gone. - add device again => the PV is not detected, because systemd sees the lvm2-pvscan@.service as active and thus doesn't restart it. The original purpose of this logic was to avoid volumes being scanned over and over again. With systemd background jobs, that isn't necessary, because systemd will not restart the job as long as it's active. Signed-off-by: Martin Wilck <mwilck@suse.com>
2018-04-17 12:38:12 +03:00
Keep systemd vars on change event in 69-dm-lvm-metad.rules for systemd reload.
udev: explicit pvscan rule in 69-dm-lvm-metad.rules Make the distinction between the cases with and without systemd background jobs explicit in 69-dm-lvm-metad.rules rather than substituting the rule from the Makefile. At this stage, this improves only readibility, at the cost of one GOTO statement. This patch introduces no functional change to the udev rules. Signed-off-by: Martin Wilck <mwilck@suse.com>
2018-04-17 12:32:52 +03:00
Write systemd and non-systemd rule in 69-dm-lvm-metad.rules, GOTO active one.
test: add lvcreate-raid-volume_list Test that no (Sub)LV remnants persist if the volume group is not listed in configuration variable activation/volume_list, hence not activatable thus causing initialization of rmeta SubLVs to fail. Related: rhbz1161347
2018-04-06 16:25:46 +03:00
Add test for activation/volume_list (Sub)LV remnants.
cache: disallow to combine format 2 with mq Only policy 'smq' is meant to be used with format version 2. Code used to let pass 'mq' policy also with format 2. But 'mq' is obsoloted wth smq and kernel currently matches it. But this is incompatible with older original mq logic - so disallow creation of this rather useless combination.
2018-03-19 12:23:48 +03:00
Disallow usage of cache format 2 with mq cache policy.
lvconvert: accept striped LV as snapshot COW LV Restore back acceptance of striped LV to be valid COW LV.
2018-03-17 16:01:09 +03:00
Again accept striped LV as COW LV with lvconvert -s (2.02.169).
raid: fix version check of target Comparision missed to check patch level for matching minor version. Howerver since all checked patchlevels were 0 - the fix doesn't change result.
2018-03-17 23:44:53 +03:00
Fix raid target version testing for supported features.
pools: skip checks when tools are missing If the tools for checking thin_pool or cache metadata are missing, issue rather just a WARNING, but let the operation of activation continue. This has the advantage, the if user is missing those tools, but he already started to use thinpool or cacheing, he can access these volumes with a WARNING. Also if the user is using too old tools i.e. for CacheV2 format dmpd tool 0.7 is required - provide informative WARNING and skip failure from older tool version which can't understand new format V2.
2018-03-17 23:50:03 +03:00
Allow activation of pools when thin/cache_check tool is missing.
lvcreate: remove RaidLV on creation failure In case a newly created RaidLV is blacklisted using config \"activation { volume list = [ ... ] }\" (i.e. its SubLVs stay inactive), the metadata SubLVs can't get wiped thus failing the creation. As a result, the RaidLV together with its SubLVs is left behind in an inconsistent state. Fix by removing the RaidLV and provide a hint about volume_list reasoning. Resolves: rhbz1161347
2018-03-16 17:47:12 +03:00
Remove RaidLV on creation failure when rmeta devices can't be activated.
locking: introduce prioritized_section Introduce prioritized_section() as a closer match to previous logic of critical_section() that has been held over longer sequence of ioctl commands - essentially it's matching operation on a single cookie. While 'critical_section()' now corresponds to locked memory - we hold this memory only between suspend/resume thus notion of 'cookie' was lost. This patch restores some logic unintentionaly lost with dropping memory locking for just activation/deactivation calls.
2018-03-15 11:07:24 +03:00
Add prioritized_section() to restore cookie boundaries (2.02.177).
devcache: add reason and always log_error With these read errors it's useful to know the reason. Also avoid to log error just once so we know exactly how many times we did failing read. On the other hand reduce repeated log_error() on code 'backtrace' path and change severity of message to just log_debug() so the actual read error is printed once for one read.
2018-03-14 21:33:20 +03:00
Enhance error messages when read error happens.
mirror: correct locking for mirror log initialization The code was not acking proper lock holding LVs when trying to initialize mirror log to predefined values.
2018-03-13 14:48:36 +03:00
Enhance mirror log initialization for old mirror target.
scanning: skip more private devices Just like lvm2 has internal devices like _tdata which is using UUID with suffix, there is similar private type of device for crypto device where they are using CRYPT-TEMP uuid prefix. Also ignore stratis.
2018-03-09 16:49:38 +03:00
Skip private crypto and stratis devices.
raid: skip frozen raid devices Some kernel version suffer from bad state transition where a device steps into 'frozen' mode. Any application that tries to read such raid gets unfortunatelly bloked. As some sort of protection try to skip such raid device from being scanned to minimize chances to block lvm2 command on such scan. When such device is found, warning gets printed.
2018-03-08 15:18:39 +03:00
Skip frozen raid devices from scanning.
pre-release
2018-05-24 16:13:10 +03:00
Activate RAID SubLVs on read_only_volume_list readwrite.
Offer convenience type raid5_n converting to raid10.
snapshot: skip invalid snapshost When scanning DM device, skip automatically invalid snapshot devices. They behave just like 'error' device.
2018-03-08 12:32:15 +03:00
Automatically avoid reading invalid snapshots during device scan.
snapshot: keep COW writable for read-only volumes When snapshot is created in read-only mode with 'lvcreate -s -pr...', lvm2 still needs to be able to write to layered -cow volume to store metadata and exceptions blocks. TODO: in some case we might be able to do full tree with read-only volume but this probably needs futher validation: 1. checking snapshot header already exist 2. origin & snapshot are both in read-only mode.
2018-03-08 12:27:04 +03:00
Ensure COW device is writable even for read-only thick snapshots.
activation: support activation of component LVs Occasionaly users may need to peek into 'component devices. Normally lvm2 does not let users activation component. This patch adds special mode where user can activate component LV in a 'read-only' mode i.e.: lvchange -ay vg/pool_tdata All devices can be deactivated with: lvchange -an vg | vgchange -an....
2018-02-28 19:16:17 +03:00
Support activation of component LVs in read-only mode.
activation: add base lv component function Introduce: lv_is_component() check is LV is actually a component device. lv_component_is_active() checking if any component device is active. lv_holder_is_active() is any component holding device is active.
2018-02-27 16:13:00 +03:00
Extend internal library to recognize and work with component LV.
lvremove: drop duplicate check for active LV Since this code branch already tested LV is active, avoid repeating same query.
2018-03-06 15:31:06 +03:00
Skip duplicate check for active LV when prompting for its removal.
lvcreate: fix activation of cached LV Since LV for caching can be already a stacked LV, proper activation needs to use lock holding LV.
2018-03-05 14:54:39 +03:00
Activate correct lock holding LV when it is cached.
raid: move VG update after archiving happened Update of LV le_count needs to happen after archive().
2018-03-06 15:38:00 +03:00
Do not modify archived metadata when removing striped raid.
raid: fix error path for lv_raid_data_offset Avoid using allocated status on error path.
2018-03-02 17:49:12 +03:00
Fix memleak on error path when obtaining lv_raid_data_offset.
lvresize: check external origin with new size Instead of checking with existing size of external origin LV, use correctly the new 'wanted' size of this LV whether it fits the limitiation requirements for older thin-pool target. Otherwise code started to the the resize, updates metadata and just fails during 'resize' in case the LV was active. For inactive LV operation could have actually passed.
2018-02-28 19:04:26 +03:00
Fix compatibility size test of extended external origin.
lv_manip: enhance for_each_sub_lv Fix missing 'externalLV' traversing for thins with external origins. Replace extra for_each_sub_lv_except_pools() with better internal logic allowing selectively to cut of processed subLV tree. Extend error code for function 'fn()' when it returns -1 it will stop futher tree scan for given LV. Also a bit simplify code to have only one place that is calling 'fn()' and use level counter to know depth of traversing. Update renaming travering to skip trees for pools and external origins.
2018-02-28 19:00:33 +03:00
Add external_origin visiting in for_each_sub_lv().
locking: move cache dropping to primary locking code While 'file-locking' code always dropped cached VG before lock was taken - other locking types actually missed this. So while the cache dropping has been implement for i.e. clvmd, actually running command in cluster keept using cache even when the lock has been i.e. dropped and taken again. This rather 'hard-to-hit' error was noticable in some tests running in cluster where content of PV has been changed (metadata-balance.sh) Fix the code by moving cache dropping directly lock_vol() function. TODO: it's kind of strange we should ever need drop_cached_metadata() used in several places - this all should happen automatically this some futher thinking here is likely needed.
2018-02-19 18:31:52 +03:00
Ensure cluster commands drop their device cache before locking VG.
locking: exclusive can be either remote or local When LOCK is exclusive and LV is already locally active, it cannot be active remotely.
2018-02-15 01:06:49 +03:00
Do not report LV as remotely active when it's locally exclusive in cluster.
cleanup: add missing WARNING ATM log_warn() is supposed to be used with WARNING: prefix.
2018-02-15 15:49:45 +03:00
Add deprecate messages for usage of mirrors with mirrorlog.
activation: separate reporting of error and monitoring status Avoid using same return code for reporting 2 different things and stricly report error code by return value and add new parameter for reporting monitoring status. This makes easier to recognize which error we got from dm_event and continue only with ENOENT.
2018-01-29 18:28:57 +03:00
Separate reporting of monitoring status and error status.
vgimportclone: add some dm_snprintf checks Check if the generated vg name still fits the buffer. So too long strings are rejected. Drop -1 from size passed to snprintf - as the \0 is already included.
2018-02-09 19:06:30 +03:00
Improve validation of created strings in vgimportclone.
toolcontext: light context missed to set-up mem mempool If cmd->mem was null, then systemd generator was failing on: (gdb) bt dm_pool_alloc_aligned (p=0x0, s=96, alignment=8) at mm/pool-fast.c:95 dm_pool_alloc (p=0x0, s=96) at mm/pool-fast.c:90 dm_pool_zalloc (p=0x0, s=96) at mm/pool.c:74 config_file_read_fd (mem=0x0, cft=0x55f4339dbad0, dev=0x55f4339dfac0, reason=DEV_IO_MDA_CONTENT, offset=0, size=82293, offset2=0, size2=0, checksum_fn=0x0, checksum=0, checksum_only=0, no_dup_node_check=0, ioflags=0, config_file_read_fd_callback=0x0, config_file_read_fd_context=0x0) at config/config.c:567 config_file_read (mem=0x0, cft=0x55f4339dbad0) at config/config.c:658 config_file_open_and_read (config_file=0x7f49aef14540 <config_file> "/var/tmp/lvm/etc/lvm/lvm.conf", source=CONFIG_FILE, cmd=0x55f4339d6260) at config/config.c:282 _load_config_file (cmd=0x55f4339d6260, tag=0x7f49aeca15da "", local=0) at commands/toolcontext.c:824 _init_lvm_conf (cmd=0x55f4339d6260) at commands/toolcontext.c:853 create_config_context () at commands/toolcontext.c:1814 lvm_config_find_bool (libh=0x0, config_path=0x55f431a884ad "global/use_lvmetad", fail=0) at lvm_base.c:144 main ()
2018-02-09 17:39:14 +03:00
Add missing initialisation of mem pool in systemd generator.
toolcontext: do not change stream for pthreaded programs With pthreaded daemons like 'dmeventd' using liblvm via plugin, lvm2 actually should not 'play' with streams at all - as there could be parallel outputs running. As a current quick workaround just disable change for pthreaded program (gettid() != getpid()). TODO: it's possible the change of buffering actually doesn't serve us any measurable benefit and could be dropped as whole later...

2018-02-09 02:26:22 +03:00
Do not reopen output streams for multithreaded users of liblvm.
configure: ensure path /usr/sbin is checked for some tools Some tools are typically installed into /usr/sbin (or /sbin) dir. And some systems do not add this path to user's $PATH var. Ensure sbin paths are looked through...
2018-01-29 18:20:53 +03:00
Configure ensures /usr/bin dir is checked for dmpd tools.
pvmove: reinstantiate clustered pvmove In fact pvmove does support 'clustered-core' target for clustered pvmove of LVs activated on multiple nodes. This patch restores support for activation of pvmove on all nodes for LVs that are also activate on all nodes.
2018-01-31 12:53:09 +03:00
Restore pvmove support for wide-clustered active volumes (2.02.177).
activation: guard exclusive activation Add protectional internall error whenever we spot activation of 'exclusive' only segments in 'non-exclusive' mode. TODO: possibly the activation locking could be enhanced to handle this fully behind the scene - as for now this works purely for lvchange/vgchange activation.
2018-01-15 18:26:00 +03:00
Avoid non-exclusive activation of exclusive segment types.
pvmove: fix _remove_sibling_pvs_from_trim_list Fix the function to really check it sibling raid image LV. For LV_rmeta_0 check for LV_rimage_0 instead of LV_rmeta_0rimage_0.
2018-01-11 15:21:08 +03:00
Fix trimming sibling PVs when doing a pvmove of raid subLVs.
lvconvert: use excl activation for conversion Use properly exclusive activation when reactivating origin after snapshot merge (since origin must have been previously also exlusively activated). Same applies when converting volumes to thin-pool or cache. Previously used 'only' local activation incorrectly allowed local activation of some targets (i.e. raid) - thus 'leaking' chance to activate same device on another node - which can be a problem for device types like raid.
2018-01-12 15:34:13 +03:00
Preserve exclusive activation during thin snaphost merge.
allocation: Avoid exceeding array bounds in allocation tag code If _limit_to_one_area_per_tag() changes nothing it writes beyond the array.
2018-01-10 05:03:32 +03:00
Avoid exceeding array bounds in allocation tag processing.

Version 2.02.177 - 18th December 2017
=====================================
format_text: Round size written up to multiple of 4096. Zero-fill metadata up to the next 4096 boundary then write out a multiple of 4096 bytes to avoid triggering a read-modify-write.
2017-12-13 01:52:22 +03:00
When writing text metadata content, use complete 4096 byte blocks.
format_text: Change metadata alignment from 512 to 4096. If there is sufficient space in the metadata area, align the next metadata to a disk offset that is a multiple of 4096 bytes and don't write it circularly. If it doesn't all fit at the end of the metadata area, go back to the start and write it all there contiguously. If there is insufficient space to use the new stricter rules, revert to the original behaviour, aligning on 512-byte boundaries wrapping around the circular buffer as required.
2017-12-12 23:57:36 +03:00
Change text format metadata alignment from 512 to 4096 bytes.
metadata: Consistently skip metadata areas that failed. Even after writing some metadata encountered problems, some commands continue (rightly or wrongly) and attempt to make further changes. Once an mda is marked MDA_FAILED, don't try to use it again. This also applies when reverting, where one loop already skips failed mdas but the other doesn't. This fixes some device open_count warnings on relevant failure paths.
2017-12-12 20:49:35 +03:00
When writing metadata, consistently skip mdas marked as failed.
format_text: Adjust metadata alignment calculation. Use new ALIGN_ABSOLUTE macro when calculating the start location of new metadata and adjust the end of buffer detection so that there is no longer an imposed gap between old and new metadata.
2017-12-11 23:25:03 +03:00
Refactor and adjust text format metadata alignment calculation.
lvmdbusd: Fix path to python3 lvmdbusd executable script must use python3 interpreter detected by configure script, as site-packages directory used for library is only used by that interpreter.
2017-12-11 14:36:54 +03:00
Fix python3 path in lvmdbusd to use value detected by configure.
vgchange: drop extra counting As the loop for background polling _poll_lvs_in_vg checks for active LVs, avoid doing unnecessary extra check before.
2017-12-08 15:17:34 +03:00
Reduce checks for active LVs in vgchange before background polling.
thin: always clear memory before parsing status Ensure there cannot be 'reused' any data from some previous call.
2017-12-06 15:24:41 +03:00
Ensure _node_send_message always uses clean status of thin pool.
Update WHATS_NEW
2017-12-06 12:41:14 +03:00
Fix lvmlockd to use pool lock when accessing _tmeta volume.
Report expected sanlock_convert errors only when retries fail.
Avoid blocking in sanlock_convert on SH to EX lock conversion.
Deactivate missing raid LV legs (_rimage_X-missing_Y_Z) on decativation.
device: Skip read-modify-write if replacing whole block.
2017-12-05 04:00:38 +03:00
Skip read-modify-write when entire block is replaced.
device: categorise block i/o Introduce enum dev_io_reason to categorise block device I/O in debug messages so it's obvious what it is for. DEV_IO_SIGNATURES /* Scanning device signatures */ DEV_IO_LABEL /* LVM PV disk label */ DEV_IO_MDA_HEADER /* Text format metadata area header */ DEV_IO_MDA_CONTENT /* Text format metadata area content */ DEV_IO_FMT1 /* Original LVM1 metadata format */ DEV_IO_POOL /* Pool metadata format */ DEV_IO_LV /* Content written to an LV */ DEV_IO_LOG /* Logging messages */
2017-12-05 02:18:56 +03:00
Categorise I/O with reason annotations in debug messages.
Update WHATS_NEW
2017-12-06 12:41:14 +03:00
Allow extending of raid LVs created with --nosync after a failed repair.
activation: split priority from memory locking When entering any critical section, lvm2 used to lock process memory and raised task priority to avoid problem with page swapping and minimize time of having non-resumed devices in table. With this patch, memory locking which which is expensive is only used when entering 'suspending' section as only in this section there is risk lvm could be suspending a device which later can be needed for paging. Raised priority is still kept for all section entrances as this is low-cost operation and may accelerate table resumes - although the real impact can be still considered later.
2017-12-01 13:50:14 +03:00
Command will lock memory only when suspending volumes.
pvmove: add missing segment merging When pvmove is finished and metadata are updated, the code missed to merge possible mergable segments - so add explicit merging call after pvmoved volumes are unlocked. This avoids weird results where i.e. lvs could have been reporting non-matching segments as lvs upon metadata read is doing silent segment merging while dm table left after pvmove was still preserving non-merged segments.
2017-11-30 00:19:46 +03:00
Merge segments when pvmove is finished.
label: Remove unused verify functions. label_verify has never been used so remove it.
2017-11-28 04:36:55 +03:00
Remove label_verify that has never been used.
cmdline: avoid overrun on very large numbers. When large size number (>2^31) is given on command line it could be misdetected and in certain cases lead to wrongly casted number. So make sure all cases always do set _MAX number in case the value would not fit within the supported range instead of getting some random value within the range. In most cases this was not a problem to detect, but i.e. stripesize parameter might have been fooled by certain large numbers.
2017-11-27 12:21:21 +03:00
Ensure very large numbers used as arguments are not casted to lower values.
toollib: improve stripes args reading Rewrite validation of stripes and stripe_size args into more readable sequential code. Extend reading of stripes & stripes_size args so it better knows defaults for types like striped raid. TODO: this should really be a value obtained for segtype structure and all the weird conditions and modification of stripes and stripe_size around lvm2 code should be dropped.
2017-11-27 12:26:35 +03:00
Enhance reading and validation of options stripes and stripes_size.
toollib: avoid printing default stripe size When user is not creating striped LV, do not print rather confusing info about default stripe size.
2017-11-18 01:02:44 +03:00
Fix printing of default stripe size when user is not using stripes.
activation: automaticaly discover pvmove holders When pvmove is finished and does 'suspend/resume' on PVMOVE LV, on resume path committed metadata are already showing 'standalone' pvmove LV prepared just for removal. However code should be able to 'resume' preloaded LV there were participating in pvmove operation. Previously this was all done in the 'tools' part of lvm2 code. So the lvconvert upon pvmove finish had to explicitely call 'resume' on every such LV. Now 'smarted' activation code is able to deduce and combine all information from the active dm table and committed metadata so single call resolves it all in one go. Internally holders are detected by reading sysfs directory to capture all needed UUID which are then looked in lvm2 metadata and all such LVs are automatically collected into dmtree.
2017-11-24 15:55:42 +03:00
Activation code for pvmove automatically discovers holding LVs for resume.
locking: pvmove is locking holding LV As we do get lock for pvmove LV - it's lockholder ATM.
2017-11-24 15:55:57 +03:00
Make a pvmove LV locking holder.
resume: secure critical section Only thin-pool with origin_only suspend is allowed to be not suspending anything. In such case pairing resume will 'decrement' critical section counter.
2017-11-24 15:53:02 +03:00
Do not change critical section counter on resume path without real resume.
suspend: handle start of pvmove Just like suspend handles preload for pvmove finish, in similar way handle suspend of starting pvmove. In this case the precommited metadata are checked for list of PVMOVEed LVs and those are suspended in with committed metadata.
2017-11-24 15:51:17 +03:00
Enhance activation code to automatically suspend pvmove participants.
Update WHATS_NEW
2017-11-30 15:30:28 +03:00
Prevent conversion of thin volumes to snapshot origin when lvmlockd is used.
Correct the steps to change lock type in lvmlockd man page.
Retry lock acquisition on recognized sanlock errors.
Fix lock manager error codes in lvmlockd.
lvmdiskscan: Remove unnecessary read. dev_get_size will open the device itself.
2017-11-16 22:13:03 +03:00
Remove unnecessary single read from lvmdiskscan.
Update WHATS_NEW
2017-11-30 15:30:28 +03:00
Check raid reshape flags in vg_validate().
Add support for pvmove of cache and snapshot origins.
pvmove: activation changes Do not use precommitted LV for suspend of pvmoving LVs.
2017-11-15 16:26:10 +03:00
Avoid using precommitted metadata for suspending pvmove tree.
pvmove: change locking on finish
2017-11-14 22:53:55 +03:00
Ehnance pvmove locking.
activate_lvs: deactivate on uniterate When activation of LVs fails prior pvmove start, try to deactivate already activated LVs. TODO: possibly remember which LVs where already activate and only those take down - devices which are already in-use will stay active.
2017-11-14 13:35:50 +03:00
Deactivate activated LVs on error path when pvmove activation fails.
log: Add io debug class
2017-11-15 03:59:30 +03:00
Add "io" to log/debug_classes for logging low-level I/O.
metadata: Eliminate redundant nested VG metadata Only lv_committed() now uses vg->vg_committed and it appears redundant if its contents match the enclosing VG so don't waste cycles creating it when that's known to be true when no write lock is held so the struct won't get modified.
2017-11-14 18:38:55 +03:00
Eliminate redundant nested VG metadata in VG struct.
persistent filter: Skip import before rescan The persistent filter should not be imported by any command that doesn't use it so take addtional note of REQUIRES_FULL_LABEL_SCAN (for vgrename) and introduce IGNORE_PERSISTENT_FILTER for vgscan and pvscan.
2017-11-13 22:45:16 +03:00
Avoid importing persistent filter in vgscan/pvscan/vgrename.
coverity: avoid memleak When security_level was set, allocated filename was leaking.
2017-11-05 20:39:05 +03:00
Fix memleak of string buffer when vgcfgbackup runs in secure mode.
clvmd: supress ENOENT error on testing connection In HA cluster, we have "clvm" resource agent to manage clvmd daemon. The agent invokes clvmd like: "clvmd -T90 -d0", which always prints a scaring error message: """ local socket: connect failed: No such file or directory """ When specifed with "-d" option, clvmd tries to check if an instance of the clvmd daemon is already running through a testing connection. The connect() will fail with this ENOENT error in such case, so supress the error message in such case. TODO: add missing error reaction code - since ofter log_error, program is not supposed to continue running (log_error() is for reporting stopping problems). Signed-off-by: Eric Ren <zren@suse.com>
2017-10-30 15:53:20 +03:00
Do not print error when clvmd cannot find running clvmd.
snapshot: prevent repeated merging Check and prevent starting another snapshot merge before exiting merging is finished. TODO: we can possibly implement smarter logic to drop existing merging and start a new one.
2017-11-05 00:15:59 +03:00
Prevent start of new merge of snapshot if origin is already being merged.
Update WHATS_NEW

2017-11-03 05:28:55 +03:00
Fix segfault in lvm_pv_remove in liblvm. (2.02.173)
validation: capture store of LV without segment
2017-10-30 16:34:30 +03:00
Do not allow storing VG metadata with LV without any segment.
thin: fix merging messages Correct reported message when thin snapshot has been already merged. So lvm2 is no longer reporting "Mergins of snapshot X will occur..." (even with swapped names).
2017-10-30 13:00:31 +03:00
Fix printed message when thin snapshot was already merged.
pool: drop create spare on error path When thin/cache pool creation fails and command created _pmspare, such volume is now removed on error path.
2017-10-28 01:10:16 +03:00
Remove created spare LV when creation of thin-pool failed.
metadata: Avoid accessing ignored metadata. When an ignored metadata area gets flagged for use again, make sure the code doesn't try to parse its old metadata. Firstly by trying to detect this situation and skipping the read (while still remembering the position reached in the circular buffer), and secondly by clearing the invalid live metadata location on disk as a precaution when subsequently writing out the precommitted metadata. Problems showed up when a metadata area in one VG got moved to another VG in ignored state (still holding metadata for the original VG) and then later got brought into use in the new VG - only the header should be read in this case, not any of the metadata content.
2017-10-28 00:42:00 +03:00
Avoid reading ignored metadata when mda gets used again.
vgsplit: Fix detection of moved PVs. vgsplit shares the vg_rename code so that must only set the PV_MOVED_VG flag introduced in commit 486ed108481cfbe4336f0fa590cbae251188ecc6 ("vgmerge: Fix intermediate metadata corruption") on PVs that moved.
2017-10-27 23:38:16 +03:00
Fix detection of moved PVs in vgsplit. (2.02.175)
WHATS_NEW: ignore stripes/stripesize on RAID takover
2017-10-26 19:18:24 +03:00
Ignore --stripes/--stripesize on RAID takeover
WHATS_NEW: missed Last patch missed to mention, we've improved/fixed generated paths in units and init.d shell scripts when lvm2 was plainly configured with just i.e. --prefix. Note: some distros might have fully specified --sbindir and --usrsbindir - thus those very not seeing problems in generated paths.
2017-10-26 15:02:44 +03:00
Improve used paths for generated systemd units and init shells.
snapshot: improve validation Do not allow to take snapshot of mirror/raid leg or log or metadata LV. This was actually never supported, but user was able to create it, and this put device stack in hardly fixable state (needs manual work). This prevents such creation to pass. Also improve validation when recreating snapshot volume type from origin and COW volume.
2017-10-24 17:34:25 +03:00
Disallow creation of snapshot of mirror/raid subLV (was never supported).
lvconvert: fixing extraction of vgname Correction to function for extracting vgname out of lvconvert parameters. Avoid repeating some checks. Add code to handle generic options which may provide vgname in its argument and compare them all so they match to a single vgname (otherwise it's a error). Extract default (envvar) vgname only when no position nor optional vgname is found. Fixing regression instroduce with patchset started with commit: 1e2420bca85da9a37570871cd70192e9ae831786 (2.02.169)
2017-10-24 15:56:42 +03:00
Fix regression in more advanced vgname extraction in lvconvert (2.02.169).
lvcreate: skip checking for name restriction for caching lvcreate supports a 'conversion' when caching LV. This normally worked fine, however in case passed LV was thin-pool's data LV with suffix _tdata we have failed to early. As the easiest fix looks dropping validation of name when caching type is select - such name check will happen later once the VG is opened again and properly detect if the LV with protected name already exists and can be converted, or will be rejected as ambigiuous operation requiring user to specify --type cache | --type cache-pool.
2017-10-23 12:36:51 +03:00
Allow lvcreate to be used for caching of _tdata LV.
lvextend: detect stacked cache lv used for thinpool Ensure, that cacheLV is not tried to be resize until full support is added.
2017-10-23 12:20:32 +03:00
Avoid internal error when resizing cache type _tdata LV (not yet supported).
lvconvert: preserve names of converted LV When prompting and warning for conversion, remember initial LV names, so after conversion is finished, correct original names are printed.
2017-10-23 11:56:44 +03:00
Show original converted names when lvconverting LV to pool volume.
liblvm: Move lib code used exclusively into metadata-liblvm.c Also remove some redundant function definitions from metadata.h.
2017-10-18 21:29:32 +03:00
Move lib code used only by liblvm into metadata-liblvm.c.
device: Separate errors for dev not found and filtered. Replaced the confusing device error message "not found (or ignored by filtering)" by either "not found" or "excluded by a filter". (Later we should be able to say which filter.) Left the the liblvm code paths alone.
2017-10-17 04:12:41 +03:00
Distinguish between device not found and excluded by filter.
thin: monitor also external origin Add missing monitoring for external origin LVs and add -real suffix for UUID used for monitoring of external origin.
2017-10-16 16:05:57 +03:00
Monitor external origin LVs.
replicator: remove the code It has not been used in a long time and is not expected to be used further.
2017-10-13 22:43:15 +03:00
Remove the replicator code, including configure --with-replicators.

Version 2.02.175 - 6th October 2017
===================================
fsadm: add --help Newer version of blockdev tool needs --help as the tool is no longer printing help without this option like it used to in past.
2017-10-05 11:16:20 +03:00
Use --help with blockdev when checking for --getsize64 support in fsadm.

Dump lvmdbusd debug information with SIGUSR1.
vgmerge: Fix intermediate metadata corruption vgmerge suffers from a similar problem to the one fixed in commit 8146548d25e9104f0d530d943290d448c1994c0a ("vgsplit: Fix intermediate metadata corruption.") When merging, splitting or renaming VGs, use a new PV status flag PV_MOVED_VG to mark the PVs that hold metadata with the old VG name and use this to provide PV-level granularity instead of incorrectly assuming all PVs in the VG are the same.
2017-10-06 04:12:42 +03:00
Fix metadata corruption in vgsplit and vgmerge intermediate states.
Add PV_MOVED_VG PV status flag to mark PVs moving between VGs.
pre-release
2017-10-07 00:10:48 +03:00
Fix lvmdbus hang and recognise unknown VG correctly.
Improve error messages when command rules fail.
pvmove: require LV name in a shared VG In a shared VG, only allow pvmove with a named LV, so that only PE's used by the LV will be moved. The LV is then activated exclusively, ensuring that the PE's being moved are not used from another host. Previously, pvmove was mistakenly allowed on a full PV. This won't work when LVs using that PV are active on other hosts.
2017-09-19 21:08:41 +03:00
Require LV name with pvmove in a shared VG.
lvmlockd: activate mirror LVs in shared mode with cmirrord Previously lvmlockd disallowed mirror LVs to be activated in shared mode.
2017-09-19 19:52:36 +03:00
Allow shared active mirror LVs with lvmlockd, dlm, and cmirrord.
lvconvert: support repair of cache/cachepool Extend repair for cache and cachepool target and user 'lvconvert_repair' routine name.
2017-09-18 12:33:47 +03:00
Support lvconvert --repair with cache and cachepool volumes.
lvconvert: repair supports poometadatespare switch Enable handling of --poolmetadataspare so if user can prevent creation of _pmspare volume during --repair operation (just like during actual lvcreate or lvconvert) for pool volumes.
2017-09-13 12:48:15 +03:00
lvconvert --repair respects --poolmetadataspare option.
pre-release
2017-10-07 00:10:48 +03:00

Version 2.02.174 - 13th September 2017
======================================
lvmlockd: always disallow mirror splitting lv_raid_split() was correctly prevented in a shared VG, but lv_raid_split_and_track() was missing that check.
2017-09-05 18:26:58 +03:00
Prevent raid1 split with trackchanges in a shared VG.
lvmlockd: avoid double unlock of client_mutex Avoid double unlocking of client_mutex and and unlock client_mutex in 'else' branch since it's already unlocked in 'if (cl->dead)' branch.
2017-08-25 15:07:45 +03:00
Avoid double unlocking of client & lockspace mutexes in lvmlockd.
locking: avoid descriptor leak for nonblocking mode When file-locking mode failed on locking, such description was leaked (typically not an issue since command usually exists afterwards). So shirt close() at the end of function and use it in all error paths. Also make sure, when interrrupt is detected, it's really not holding lock and returns 0.
2017-08-25 12:59:19 +03:00
Fix leaking of file descriptor for non-blocking filebased locking.
pvcreate: fix check for 2nd mda at end of disk fits if using pvcreate --restorefile Fix code checking that the 2nd mda which is at the end of disk really fits the available free space and avoid any DA and MDA interleaving when we already have DA preallocated. This mainly applies when we're restoring a PV from VG backup using pvcreate --restorefile where we may already have some DA preallocated - this means the PV was in a VG before with already allocated space from it (the LVs were created). Hence we need to avoid stepping into DA - the MDA can never ever be inside in such case! The code responsible for this calculation was already in _text_pv_add_metadata_area fn, but it had a bug in the calculation where we subtracted one more sector by mistake and then the code could still incorrectly allocate the MDA inside existing DA. The patch also renames the variable in the code so it doesn't confuse us in future. Also, if the 2nd mda doesn't fit, don't silently continue with just 1 MDA (at the start of the disk). If 2nd mda was requested and we can't create that due to unavailable space, error out correctly (the patch also adds a test to shell/pvcreate-operation.sh for this case).
2017-08-15 14:23:51 +03:00
Fix check for 2nd mda at end of disk fits if using pvcreate --restorefile.
pvcreate: Use maximum metadata area size with --restorefile If the PV was originally created with a larger-than-default metadata area the restored one wasn't and might not even be large enough to hold the metadata!
2017-08-11 22:41:37 +03:00
Use maximum metadataarea size that fits with pvcreate --restorefile.
pvcreate: Wipe cached bootloaderarea when wiping label. Previously the cache remembered an existing bootloaderarea and reinstated it (without even checking for overlap) when asked to write out the PV. pvcreate could write out an incorrect layout.
2017-08-11 22:32:04 +03:00
Always clear cached bootloaderarea when wiping label e.g. in pvcreate.
pvcreate: Disallow --bootloaderareasize with --restorefile. The backup file already holds the bootloader area details to use so don't overcomplicate things.
2017-08-11 22:28:53 +03:00
Disallow --bootloaderareasize with pvcreate --restorefile.
lvmlockd: fix lm running check during adoption When trying to adopt locks in startup, we want to ignore a lock manager that isn't running, not fail.
2017-08-07 18:37:22 +03:00
Fix lvmlockd check for running lock managers during lock adoption.
lvmconfig: Add options to produce file preamble Use --withgeneralpreamble and --withlocalpreamble instead of concatenating files.
2017-08-05 18:18:36 +03:00
Add --withgeneralpreamble and --withlocalpreamble to lvmconfig.
Improve makefiles' linking.
man: fix generated paths Use user configured paths instead of some developers paths ;)
2017-08-01 12:17:04 +03:00
Fix some paths in generated makefiles to respected configured settings.
thin: warn about too big chunks size lvm2 warned about zeroing and too big chunksize (>=512KiB), but only during lvconvert, so lvcreate was creating thin-pools without any warning about possible slowness of thin provisioning because of zeroing.
2017-07-21 21:58:33 +03:00
Add warning when creating thin-pool with zeroing and chunk size >= 512KiB.
tools: Introduce exit code EINIT_FAILED. Replace -1 (reported as 255) by 4.
2017-07-27 01:18:03 +03:00
Introduce exit code 4 EINIT_FAILED to replace -1 when initialisation fails.
raid: reshape synchronization point Give udev time to get in sync and give md-core time to wake up after table reload.
2017-07-20 20:04:59 +03:00
Add synchronization points with udev during reshape of raid LVs.

=================================
pre-release
2017-07-20 18:57:27 +03:00
Add synchronization points with udev during conversion of raid LVs.
lvmcmdline: validate size as double Since we are reading size as (double) we can get way bigger number then just plain int64. So to make this check actually more valid and usable do a maxsize compare in 'double'.
2017-07-16 10:53:49 +03:00
Improve --size args validation and report more detailed error message.
clvmd: fix valgrind warning Initialize mutex upfront any debugging and fix this report: Mutex reinitialization: mutex 0x485d20, recursion count 0, owner 1. at 0x4C38480: pthread_mutex_init_intercept (drd_pthread_intercepts.c:821) by 0x4C38480: pthread_mutex_init (drd_pthread_intercepts.c:830) by 0x11F359: main (clvmd.c:562) mutex 0x485d20 was first observed at: at 0x4C38F63: pthread_mutex_lock_intercept (drd_pthread_intercepts.c:885) by 0x4C38F63: pthread_mutex_lock (drd_pthread_intercepts.c:898) by 0x11E920: debuglog (clvmd.c:254) by 0x11F1D8: main (clvmd.c:527)

Initialize debugging mutex before any debug message in clvmd.
pre-release
2017-07-20 18:57:27 +03:00
Log error instead of warn when noticing connection problem with lvmetad.
lvmetad: fix memory leaks Hash tables need to release no longer needed inserted data.
2017-07-16 11:20:37 +03:00
Fix memory leak in lvmetad when working with duplicates.
pre-release
2017-07-20 18:57:27 +03:00
Remove restrictions on reshaping open and clustered raid devices.
Add incompatible data_offset to raid metadata to fix reshape activation.
commands: fix lvm shell segfaults Don't check for -h/--help if argc is 1.
2017-07-11 03:42:06 +03:00
Accept 'lvm -h' and 'lvm --help' as well as 'lvm help' for help.
lvmetad: Suppress accept error on clean shutdown Also fix error message after pthread_create() error in handle_connect().
2017-07-06 16:53:10 +03:00
Suppress error message from accept() on clean lvmetad shutdown.
clvmd: Fix client list corruption Centralise editing of the client list into _add_client() and _del_client(). Introduce _local_client_count to track the size of the list for debugging purposes. Simplify and standardise the various ways the list gets walked. While processing one element of the list in main_loop(), cleanup_zombie() may be called and remove a different element, so make sure main_loop() refreshes its list state on return. Prior to this patch, the list edits for clients disappearing could race against the list edits for new clients connecting and corrupt the list and cause a variety of segfaults. An easy way to trigger such failures was by repeatedly running shell commands such as: lvs &; lvs &; lvs &;...;killall -9 lvs; lvs &; lvs &;... Situations that occasionally lead to the failures can be spotted by looking for 'EOF' with 'inprogress=1' in the clvmd debug logs.
2017-07-01 03:34:38 +03:00
Tidy clvmd client list processing and fix segfaults.
clvmd: add client id to debug log messages Use standard format to make it easier to find the client to which each debug log message refers.
2017-07-01 03:17:40 +03:00
Protect clvmd debug log messages with mutex and add client id.
fsadm: fix shell globbing Fixing reported issue for shellcheck. Use "" properly to avoid having shell variables split.
2017-06-29 14:15:47 +03:00
Fix shellcheck reported issues for script files.

Version 2.02.172 - 28th June 2017
=================================
cmdline: fix missing NULL at end of array of args lvm_run needs to place NULL as the last element into argv[]. Otherwise we get: Conditional jump or move depends on uninitialised value(s) _command_required_pos_matches (lvmcmdline.c:1443) _find_command (lvmcmdline.c:1610) lvm_run_command (lvmcmdline.c:2770) lvm2_run (lvmcmdlib.c:91)
2017-06-26 21:03:05 +03:00
Add missing NULL to argv array when spliting cmdline arguments.
display: add display_percent function Add universal function to print dm_percent_t values via single code path. TODO: extend with configurale precision of printed values.
2017-06-24 17:03:21 +03:00
Add display_percent helper function for printing percent values.
pre-release
2017-06-28 18:38:46 +03:00
lvconvert --repair handles failing raid legs (present but marked 'D'ead).
cache: fix lvdisplay output Unused cache pool may have lots of fields actually undefined, so avoid printing them, if they are not specified in metadata.
2017-06-22 21:05:26 +03:00
Do not lvdisplay --maps unset settings of cache pool.
cache: fix lvdisplay --maps 'lvdisplay -m' tried to go through NULL policy settings, when such policy was not defined for CachedLV. Patch is fixing display of cache-pool without defined settings, as this is now a valid pool and we mostly want users to define these settings when actually really caching a LV.
2017-06-22 20:53:27 +03:00
Fix lvdisplay --maps for cache pool without policy settings.
cache: make syncing abortable by user When user runs command like 'lvconvert --splitcache' the operation might be actually either slow or not making any progress in kernel, so lets give user a chance to abort such operation. When user press 'Ctrl+C' device table is restored to pre-flushing state.
2017-06-22 18:08:47 +03:00
Support aborting of flushing cache LV.
thin: restore conversion to raid Since commit 1bc546269a7d2cae156827e282715410a4967d51 we've disabled coversion of raid. This however already got fixed, so reenable commands like: 'lvconvert --type raid1 vg/pool_tdata'.
2017-06-20 00:11:11 +03:00
Reenable conversion of data and metadata thin-pool volumes to raid.
raid: report percent with segtype info Enhance reporting code, so it does not need to do 'extra' ioctl to get 'status' of normal raid and provide percentage directly. When we have 'merging' snapshot into raid origin, we still need to get this secondary number with extra status call - however, since 'raid' is always a single segment LV - we may skip 'copy_percent' call as we directly know the percent and also with better precision. NOTE: for mirror we still base reported number on the percetage of transferred extents which might get quite imprecisse if big size of extent is used while volume itself is smaller as reporting jump steps are much bigger the actual reported number provides. 2nd.NOTE: raid lvs line report already requires quite a few extra status calls for the same device - but fix will be need slight code improval.
2017-06-16 14:20:25 +03:00
Improve raid status reporting with lvs.
pre-release
2017-06-28 18:38:46 +03:00
No longer necessary to '--force' a repair for RAID1.
lvconvert: linear -> raid1 upconvert should cause "recover" not "resync" Two of the sync actions performed by the kernel (aka MD runtime) are "resync" and "recover". The "resync" refers to when an entirely new array is going through the process of initializing (or resynchronizing after an unexpected shutdown). The "recover" is the process of initializing a new member device to the array. So, a brand new array with all new devices will undergo "resync". An array with replaced or added sub-LVs will undergo "recover". These two states are treated very differently when failures happen. If any device is lost or replaced while "resync", there are no worries. This is because any writes created from the inception of the array have occurred to all the devices and can be safely recovered. Even though non-initialized portions will still be resync'ed with uninitialized data, it is ok. However, if a pre-existing device is lost (aka, the original linear device in a linear -> raid1 convert) during a "recover", data loss can be the result. Thus, writes are errored by the kernel and recovery is halted. The failed device must be restored or removed. This is the correct behavior. Unfortunately, we were treating an up-convert from linear as a "resync" when we should have been treating it as a "recover". This patch removes the special case for linear upconvert. It allows each new image sub-LV to be marked with a rebuild flag and treats the array as 'in-sync'. This has the correct effect of causing the upconvert to be treated as a "recover" rather than a "resync". There is no need to flag these two states differently in LVM metadata, because they are already considered differently by the kernel RAID metadata. (Any activation/deactivation will properly resume the "recover" process and not a "resync" process.) We make this behavior change based on the presense of dm-raid target version 1.9.0+.
2017-06-14 16:33:42 +03:00
Linear to RAID1 upconverts now use "recover" sync action, not "resync".
cache: lvcreate --cachepool checks for cache pool Code path missed validation of lvcreate --cachepool argument. If the non cache-pool LV was passed in, code has still continued further work and failed later on internal error. Validate this condition at right place now.
2017-06-09 11:59:37 +03:00
Improve lvcreate --cachepool arg validation.
pre-release
2017-06-28 18:38:46 +03:00
Limit maximum size of thin-pool for specific chunk size.
print warning about in-use orphans Warn about a PV that has the in-use flag set, but appears in the orphan VG (no VG was found referencing it.) There are a number of conditions that could lead to this: . The PV was created with no mdas and is used in a VG with other PVs (with metadata) that have not yet appeared on the system. So, no VG metadata is found by lvm which references the in-use PV with no mdas. . vgremove could have failed after clearing mdas but before clearing the in-use flag. In this case, the in-use flag needs to be manually cleared on the PV. . The PV may have damanged/unrecognized VG metadata that lvm could not read. . The PV may have no mdas, and the PVs with the metadata may have damaged/unrecognized metadata.
2017-06-01 19:10:09 +03:00
Print a warning about in-use PVs with no VG using them.
disable repairing in-use flag on orphan PVs A PV holding VG metadata that lvm can't understand (e.g. damaged, checksum error, unrecognized flag) will appear as an in-use orphan, and will be cleared by this repair code. Disable this repair until the code can keep track of these problematic PVs, and distinguish them from actual in-use orphans.
2017-05-26 21:26:09 +03:00
Disable automatic clearing of PVs that look like in-use orphans.
flags: add segtype flag support Switch METADATA_FORMAT flag usage to be stored via segtype instead of 'status' flag which appeared to cause major incompatibility troubles. For backward compatiblity segtype flags are still accepted also via 'status' bits which were used from version 2.02.169 so metadata saved by this newer lvm2 version should still work nicely, although new save version will no longer work on this older lvm2 version.
2017-05-29 15:20:38 +03:00
Cache format2 flag is now using segment name type field.
flags: add read and print of segtype flag Allow storing LV status bits with segment type name field. Switching to this since this field has better support for compatibility with older version of lvm2 - since such unknown segtype will not cause complete invisiblity of metadata from older lvm2 code - just the particular LV will become unusable with unknown type of segment.
2017-05-29 15:20:05 +03:00
Support storing status flags via segtype name field.
fsadm: avoid hidden --yes When 'fsadm' was running without terminal (i.e. pipe), it's been automatically working like in '--yes'. Detect terminal and only accept empty "" input in this mode.
2017-05-23 14:58:12 +03:00
Stop using '--yes' mode when fsadm runs without terminal.
fsadm: enhance detection of already mounted volumes Add more validation to catch mainly renamed devices, where filesystem utils are not able to handle devices properly, as they are not addressed by major:minor by rather via some symbolic path names which can change over time via rename operation.
2017-05-10 16:32:48 +03:00
Extend validation of filesystems resized by fsadm.
lvconvert: enhance automatic settings of possible (raid) LV types Offer possible interim LV types and display their aliases (e.g. raid5 and raid5_ls) for all conversions between striped and any raid LVs in case user requests a type not suitable to direct conversion. E.g. running "lvconvert --type raid5 LV" on a striped LV will replace raid5 aka raid5_ls (rotating parity) with raid5_n (dedicated parity on last image). User is asked to repeat the lvconvert command to get to the requested LV type (raid5 aka raid5_ls in this example) when such replacement occurs. Resolves: rhbz1439403
2017-05-18 01:18:15 +03:00
Enhance lvconvert automatic settings of possible (raid) LV types.
lvchange: allow changing properties on thin pool data lv Add an exception to not allowing lvchange to change properties on hidden LVs. When a thin pool data LV is a cache LV, we need to allow changing cache properties on the tdata sublv of the thin pool.
2017-05-15 18:57:49 +03:00
Allow lvchange to change properties on a thin pool data sub LV.
lvcreate: Fix mirror percentage size calculations. Trap cases where the percentage calculation currently leads to an empty LV and the message: Internal error: Unable to create new logical volume with no extents Additionally convert the calculated number of extents from physical to logical when creating a mirror using a percentage that is based on Physical Extents. Otherwise a command like 'lvcreate -m3 -l80%FREE' can never leave any free space. This brings the behaviour closer to that of lvresize. (A further patch is needed to cover all the raid types.)
2017-05-12 04:04:05 +03:00
Fix lvcreate extent percentage calculation for mirrors.
metadata: Fix metadata repair when devs still missing. _check_reappeared_pv() incorrectly clears the MISSING_PV flags of PVs with unknown devices. While one caller avoids passing such PVs into the function, the other doesn't. Move the check inside the function so it's not forgotten. Without this patch, if the normal VG reading code tries to repair inconsistent metadata while there is an unknown PV, it incorrectly considers the missing PVs no longer to be missing and produces incorrect 'pvs' output omitting the missing PV, for example. Easy reproducer: Create a VG with 3 PVs pv1, pv2, pv3. Hide pv2. Run vgreduce --removemissing. Reinstate the hidden PV pv2 and at the same time hide a different PV pv3. Run 'pvs' - incorrect output. Run 'pvs' again - correct output. See https://bugzilla.redhat.com/1434054
2017-05-11 04:04:50 +03:00
Don't reinstate still-missing devices when correcting inconsistent metadata.
fsadm: fix test of subshell return value Subshell is not returning error code value upward thus error results in this case were actually ignored. Also add dots to moved error messages.
2017-05-09 21:52:15 +03:00
Properly handle subshell return codes in fsadm.

Version 2.02.171 - 3rd May 2017
===============================
Fix memory warnings by using mempools for command definition processing.
fix running commands from a script file Using any arg with a command name in a script file would cause the command to fail. The name of the script file being executed was being passed to lvm_register_commands() and define_commands(), which prevented command defs from being defined (simple commands were still being defined only by name which was enough for those to still work when run trivially with no args).
2017-04-29 00:43:42 +03:00
Fix running commands from a script file.
WHATS_NEW: pvcreate prompt
2017-04-28 17:06:41 +03:00
Add pvcreate prompt when device size doesn't match setphysicalvolumesize.
lvconvert: preserve region size on raid1 image count changes (v2) Unless a change of the regionsize is requested via "lvconvert -R N ...", keep the region size when the number of images changes in a raid1 LV. Related: rhbz1443705
2017-04-27 16:52:25 +03:00
lvconvert - preserve region size on raid1 image count changes
WHATS_NEW: pvcreate --setphysicalvolumesize

Adjust pvresize/pvcreate messages and prompt if underlying dev size differs.
Revert "lvconvert: preserve region size on raid1 image count changes" This reverts commit 8333d5a969042a321f00656271bd55a37c1ea179.
2017-04-27 16:29:03 +03:00
raid - sanely handle insufficient space on takeover.
configure: Fix notify-dbus and dmfilemapd options.
2017-04-18 22:37:53 +03:00
Fix configure --enable-notify-dbus status message.
Change configure option name prefix from --enable-lockd to --enable-lvmlockd.
WHATS_NEW: raise region_size default
2017-04-13 18:49:58 +03:00
lvcreate - raise mirror/raid default regionsize to 2MiB
conf: Add missing prefix to installation directory. Our Makefiles also support systems that set the installation prefix at configuration time - the use of DESTDIR is not required.
2017-04-13 04:17:27 +03:00
Add missing configurable prefix to configuration file installation directory.

fsadm: support configurable full path Just like with other tools lvm2 is using allow to define fully configurable path. Default is selected by $PREFIX/sbin/fsadm
2017-04-08 20:43:20 +03:00
Introduce global/fsadm_executable to make fsadm path configurable.
thin: properly check for status for max sizes metadata When metadata LV size was over DM_THIN_MAX_METADATA_SIZE sectors, the info() routine was incorrectly trying to match bigger size, while we do never pass any bigger device. Fixing a case, where lvs should be displaying status for metadata LV with 16GB size.
2017-04-08 20:38:17 +03:00
Look for limited thin pool metadata size when using 16G metadata.

Fix lvconvert when the same LV is incorrectly reused in options.
Fix lvconvert VG name validation in option values.
Fix missing lvmlockd LV locks in lvchange and lvconvert.
Fix dmeventd setup for lvchange --poll.
Fix use of --poll and --monitor with lvchange and vgchange.
Disallow lvconvert of hidden LV to a pool.
Ignore --partial option when not used for activation.

WHATS_NEW: add recent RAID entries
2017-04-12 20:41:55 +03:00
Better message on lvconvert --regionsize
Allow valid lvconvert --regionsize change
Add raid10 alias raid10_near
Handle insufficient PVs on lvconvert takeover
Fix SIGINT blocking to prevent corrupted metadata
lvmconf: fix systemd unit existence check for lvmconf --services --startstopservices We have to unset the LoadState variable from previous use when we check for systemd unit state. We use this variable to check if systemd services are loaded or not and if it is loaded, we issue systemctl commands to enable/disable and start/stop the service. We don't issue these commands if the unit is not loaded to avoid error messages which may confuse users.
2017-04-05 12:06:56 +03:00
Fix systemd unit existence check for lvmconf --services --startstopservices.
vgrename: use long enough buffer for path Use PATH_MAX when creating buffers for rename.
2017-03-30 01:17:37 +03:00
Check and use PATH_MAX buffers when creating vgrename device paths.
post-release
2017-03-28 18:14:03 +03:00
pre-release Removing some unused new lines and changing some incorrect "can't release until this is fixed" comments. Rename license.txt to make it clear its merely an included file, not itself a licence.
2017-03-28 17:28:53 +03:00
Version 2.02.169 - 28th March 2017
==================================
Automatically decide whether '-' in a man page is a hyphen or a minus sign.
Add build-time configuration command line to 'lvm version' output.
Handle known table line parameter order change in specific raid target vsns.
Conditionally reject raid convert to striped/raid0* after reshape.
Ensure raid6 upconversion restrictions.
Adjust mirror & raid dmeventd plugins for new lvconvert --repair behaviour.
WHATS_NEW: disable lvmetad for repair
2017-03-16 19:56:19 +03:00
Disable lvmetad when lvconvert --repair is run.
lvmchange: Move to a built-in command. Has been obsolete since LVM1 and it's clear we'll never implement this.
2017-03-16 04:09:29 +03:00
Remove obsolete lvmchange binary - convert to built-in command.
pre-release Removing some unused new lines and changing some incorrect "can't release until this is fixed" comments. Rename license.txt to make it clear its merely an included file, not itself a licence.
2017-03-28 17:28:53 +03:00
Show more information for cached volumes in lvdisplay [-m].
cache: enable usage of --cachemetadataformat lvcreate and lvconvert may select cache metadata format when caching LV. By default lvm2 picks best available format.
2017-02-26 22:18:37 +03:00
Add option for lvcreate/lvconvert --cachemetadataformat auto|1|2.
cache: LV supports cache segs with metadata format Cache pool read/writes metadata_format within its segment type.. For CachePoolLV unselected metadata format is NOT stored in metadata. For CacheLV when metadata format is not present/selected in lvm2 metadata, it's automatically assumed to be the version 1 (backward compatible). To ensure older lvm2 will not 'miss-read' metadata with new version 2, such LV is marked with METADATA_FORMAT status flag (segment is specifying metadata format). So when cache uses metadata format 2, it will become inaccesible on older system without such support. (kernel dm cache < 1.10, lvm2 < 2.02.169).
2017-03-01 14:26:56 +03:00
Support cache segment with configurable metadata format.
pre-release Removing some unused new lines and changing some incorrect "can't release until this is fixed" comments. Rename license.txt to make it clear its merely an included file, not itself a licence.
2017-03-28 17:28:53 +03:00
Add allocation/cache_metadata_format profilable settings.
lvconvert: share function for cache params Reuse same code for getting/setting cache parameters with lvcreate. So there is single one place how to get vars from profiles and configs. Variables declarations are moved to start of function and there is no need to initialize them as they are always defined by functions get_cache_params() and get_pool_params().
2017-02-27 16:54:08 +03:00
Use function cache_set_params() for both lvcreate and lvconvert.
lvcreate: do not round cache volumes on cache chunks Since cache chunk might be huge and there is no technical need to enforce rounding and there is actually more 'real' VG space used then necessary - keep rounding on 'chunk' bounrary only for thin volumes - where it's the space used anyway. NB: we support conversion of any-size 'existing' LV into cached LV.
2017-03-09 19:15:56 +03:00
Skip rounding on cache chunk size boudary when create cache LV.
cache: extend usability of cache_set_params Fix missing reset of '*settings' pointer when no args were given. Handle cache_chunk settings like all other settings, so it is properly updated only with non-zero settings and the existing cache-pool chunk_size is not being reconfigured.
2017-02-27 16:53:45 +03:00
Improve cache_set_params support for chunk_size selection.
cache: improve support for profile for cache settings User can specify metadata profile which stores important cache geometry data for easy configuration. Fix missing support for getting chunk_size, cache_mode, cache_policy for a cache/cache pools volumes from configuration or metadata profile.
2017-03-05 19:42:15 +03:00
Fix metadata profile allocation/cache_[mode|policy] setting.
Fix missing support for using allocation/cache_pool_chunk_size setting.
git: Upstream repository moved to sourceware.org The fedorahosted git repository shuts down tomorrow: https://communityblog.fedoraproject.org/fedorahosted-sunset-2017-02-28/ Our upstream git repository has moved back to sourceware.org.

WHATS_NEW: add entry
2017-02-24 07:24:59 +03:00
Support conversion of raid type, stripesize and number of disks
lvchange: reject writemostly/writebehind on raid1 during resync The MD kernel raid1 personality does no use any writemostly leg as the primary. In case a previous linear LV holding data gets upconverted to raid1 it becomes the primary leg of the new raid1 LV and a full resynchronization is started to update the new legs. No writemostly and/or writebehind setting may be allowed during this initial, full synchronization period of this new raid1 LV (using the lvchange(8) command), because that would change the primary (i.e the previous linear LV) thus causing data loss. lvchange has a bug not preventing this scenario. Fix rejects setting writemostly and/or writebehind on resychronizing raid1 LVs. Once we have status in the lvm2 metadata about the linear -> raid upconversion, we may relax this constraint for other types of resynchronization (e.g. for user requested "lvchange --resync "). New lvchange-raid1-writemostly.sh test is added to the test suite. Resolves: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=855895
2017-02-23 17:09:29 +03:00
Reject writemostly/writebehind in lvchange during resynchronization.
snapshot: improve removal of active origin volume Previously when lvremove tried to remove 'active' origin, it had been asking for every 'snapshot' LV separately and doing individual single snapshot removals first. To be faster it now deactivates origin before removal all connected snapshots. This avoids multiple reloads of dm table for origin volume which were unnecessary as origin was meant to be removed as well.
2017-02-22 17:12:54 +03:00
Deactivate active origin first before removal for improved workflow.
pre-release Removing some unused new lines and changing some incorrect "can't release until this is fixed" comments. Rename license.txt to make it clear its merely an included file, not itself a licence.
2017-03-28 17:28:53 +03:00
Fix regression of accepting both --type and -m with lvresize. (2.02.158)

Verify all command line items against command definition.
Match every command run to one command definition.
Specify every allowed command definition/syntax in command-lines.in.
mem: add extra mem pages for pthread stack Some archs can use even 64K pages and then lvm2 runs into trouble if the stack is 'too small' to fit extra page capturing stack overwrite. So when lvm2 limits stack - add extra mem page - be it 4K or 64K. Relates to ppc64le bug: https://bugzilla.redhat.com/1387279
2017-02-11 20:14:00 +03:00
Add extra memory page when limiting pthread stack size in clvmd.
pre-release Removing some unused new lines and changing some incorrect "can't release until this is fixed" comments. Rename license.txt to make it clear its merely an included file, not itself a licence.
2017-03-28 17:28:53 +03:00
Support striped/raid0* <-> raid10_near conversions.
Support shrinking of RaidLVs.
Support region size changes on existing RaidLVs.
clvmd: add mutex protection for cpg_ call The library for corosync multicasting is not supporting multithread usage - add local mutex to avoid parallel call of cpg_mcast_joined().
2017-02-04 16:47:27 +03:00
Avoid parallel usage of cpg_mcast_joined() in clvmd with corosync.
lvconvert: add segtypes raid6_{ls,rs,la,ra}_6 and conversions to/from it Add: - support for segment types raid6_{ls,rs,la,ra}_6 (striped raid with dedicated last Q-Syndrome SubLVs) - conversion support from raid5_{ls,rs,la,ra} to/from raid6_{ls,rs,la,ra}_6 - setting convenient segtypes on conversions from/to raid4/5/6 - related tests to lvconvert-raid-takeover.sh factoring out _lvcreate,_lvconvert funxtions Related: rhbz1366296
2017-02-05 02:53:36 +03:00
Support raid6_{ls,rs,la,ra}_6 segment types and conversions from/to it.
WHATS_NEW: New segment type raid6_n_6
2017-02-04 16:09:26 +03:00
Support raid6_n_6 segment type and conversions from/to it.
WHATS_NEW: New segment type raid5_n
2017-02-04 01:41:48 +03:00
Support raid5_n segment type and conversions from/to it.
lvmcmd2lib: support new command Internal command which reads lvm.conf settins and passes it via envvar to dmeventd monitoring thread.
2017-01-18 11:53:46 +03:00
Support new internal command _dmeventd_thin_command.
config: new option dmeventd/thin_command This setting will allowing configuring which command gets executed when thin-pool fullness goes from 50%..100%
2017-01-18 11:54:32 +03:00
Introduce new dmeventd/thin_command configurable setting.
libdm: add human R|readable units When showing sizes with 'H|human' units we do use standard rounding. This however is confusing users from time to time, when the printed number uses some biger units i.e. GiB and there is just tiny fraction of space missing. So here is some real-life example with new 'r' unit. $lvs LV VG Attr LSize Pool Origin lvol0 vg -wi-a----- 1.99g lvol1 vg -wi-a----- <2.00g lvol2 vg -wi-a----- <2.01g Meaning is - lvol1 has 'slightly' less then 2.00g - from sign '<' user can be aware the LV doesn't have full 2.00GiB in size so he will be less surpriced allocation of 2G volume will not succeed. $ vgs VG #PV #LV #SN Attr VSize VFree vg 2 2 0 wz--n- <6,00g <2,01g For uses needing 'old' undecorated human unit simply will continue to use 'H|h' units. The new R|r may further change when we would recongnize some other way how to improve readability.
2017-01-09 18:30:49 +03:00
Use new default units 'r' for displaying sizes.
blkdeactivate: also unmount mount point on top of MD device if using blkdeactivate -u The blkdeactivate script processes MD devices too so we should unmount any mount point on top of an MD device if blkdeactivate -u|--umount is called. Diagnosed and reported by: Rick Warner <rick@microway.com> See also https://bugzilla.redhat.com/show_bug.cgi?id=1410585.
2017-01-06 13:16:07 +03:00
Also unmount mount point on top of MD device if using blkdeactivate -u.
cache: resize is still unsupported During rework of resize code this validation check has been lost (in my resize branch). Upstream is still not supporting resize of any cache type LV so needs to be prevented.
2017-01-05 17:32:25 +03:00
Restore check preventing resize of cache type volumes (2.02.158).
cache: add missing udev wait When we need to clear dirty cache content of cached LV, there is table reload which usually is shortly followed by next metadata change. However udev can't (as of now) process udev event while device is 'suspended'. So whenever sequence of 'suspend/resume/suspend' is needed, we need to wait first for finishing of 'resume' processing before starting next 'suspend'. Otherwise there is 'race' danger of triggering unwantend umount by systemd as such event will trigger SYSTEMD_READY=0 state for a moment for such changed device. Such race is pretty ugly to trace so we may need to review more sequencies for missing 'sync'. (Other option is to enhnace 'udev' rules processing to avoid such dramatic actions to be happening for suspended devices).
2017-01-03 16:47:46 +03:00
Add missing udev sync when flushing dirty cache content.
vgchange: max_pv limited to uint32 Solves: https://bugzilla.redhat.com/1280496 The only reasonable behaviour here is to error on any number out of accepted range (i.e. now numbers wrapping around with some hidden logic). As this is plain bug there is no support for backward compatibility since noone should set numbers >UINT32_MAX and expect 0 or error depending on how big number was used.... TODO: more fields might need to be converted.
2017-01-03 15:04:51 +03:00
vgchange -p accepts only uint32 numbers.
report: show proper info for merging origin When there is 'merging' of an origin in progress, but metadata stil do provide both origin and snapshot, we should show data from merged snapshot. This is important mainly for thin case, where there was a window, where i.e. 'lvs -o+device_id' would report information about 'already gone' origin thin LV. This race window is usually hard to trigger but can be ocasionally hit. Usually shortly after activation, but before polling process manages to update metadata after merge.
2016-12-22 21:51:35 +03:00
Report thin LV date for merged LV when the merge is in progress.
snapshot: validate merge has started Before starting polling process, validate the merge has actually started so there is not pointless invoke of lvmpolld. This also fixes reported message from command, so user has correct info whether merging has already started or if it's delayed for next activation.
2016-12-22 21:46:02 +03:00
Detect if snapshot merge really started before polling for progress.
lv: more exact check for merging origin Merging origin has 'MERGE_LV' and should also have its merging snapshot.
2016-12-22 23:15:31 +03:00
Checking LV for merging origin requires also it has merged snapshot.
validation: rework segment validation Move individual segment validation to a separate function executed for 'complete_vg'. Move some 'extra' validation bits from 'raid' validation to global segtype validation (so extending existing normal validation) TODO: still some test are left to be moved. Reduce some duplication in validation process - there are still some left thought so still room for improving overal speed.
2016-12-20 17:59:11 +03:00
Extend validation of metadata processing.
cache: support cached origin for snapshot Enable 'lvcreate/lvconvert -s' for cached LV. and supported operations: Create a snapshot of cached LV Split/Join snapshot LV to cached origin LV.
2016-12-19 16:08:56 +03:00
Enable usage of cached volumes as snapshot origin LV.
lvconvert: fix shown lv name for snapshot split We can't keep 'display_lvname' for too long - it's using ringbuffer and keeps limited number of names. So it's safe only per few simple tests, but can't be used anymore after some function calls.. (Fixes 00e641ef37a977129acc503f3fa1b67f556ac5eb)
2016-12-19 16:06:55 +03:00
Fix displayed lv name when splitting snapshot (2.02.146).
backup: show warning once per command When command calls backup() more then once (which is actually not wanted) this warning message is shown repeatedly: "WARNING: This metadata update is NOT backed up." Instead now print message just once and less confuse user.
2016-12-18 18:36:33 +03:00
Warn about command not making metadata backup just once per command.
lvconvert: support cache to external origin conversion Add this functionality to lvconvert: 'lvconvert --thin cachedLV --thinpool vg/poll' Converts cachedLV to external origin (which will be read-only). New thin volume is created in thinpool LV and it's using external origin as source for unprovisioned chunks. This conversion happens online (while volume is in use). Thin LV remains fully writable. Cached external origin no longer could be written so cache will be used ONLY for read operations. For this limitation we require cache mode to be writethrough (as writeback cannot write to read-only volumes). When thinLV is later removed cached external origin is again fully usable, just note, LV remain in 'read-only' mode. When read-write is needed, 'lvchange -prw' has to be used. Single external origin could be user by multiple thinLV in multiple differen thin pool.
2016-12-18 00:41:27 +03:00
Enable usage of cached volume as thin volume's external origin.
cache: improve activation with -real When cache volume may be converted from normal to -real layer LV we need to improve logic for call cache_check. With this patch, we register call for cache_check only when metadata LV is not yet present in active table slot (should match initial table load). This avoids unwanted checking when cache would become layer device online.
2016-12-18 17:05:31 +03:00
Support cache volume activation with -real layer.
lv: fix lock holder for external origin External origin could be reloaded via more locks. It's actually even more complex then thin-pool, as it may be active on more nodes for linear LVs (and maybe even more types). External origin is always read-only thus unmodifiable device so there should not be a problem accesing it through multiple nodes. Also for thin-pool check first presence of active thin-pool. FIXME: It's not easy to detect on which nodes this device is active Thus manipulation with such device may require checking every node and it active state and refresh. But since such setup is quite complex to prepare and use, hopefully there are not user trying to 'explore' this usage yet.
2016-12-18 00:40:14 +03:00
Improve search of lock-holder for external origin and thin-pool.
cache: prepare status checking for layer To be ready to show status of cache volume, call the status with layer. Layer is automatically detected in this case when cache volume is used in 'layered' form (needs -real suffix).
2016-12-17 23:52:27 +03:00
Support status checking of cache volume used in layer.
cache: improve wait for cache clear Avoid printing misleading message about single dirty block. Instead properly detect condition where the 'cleaner' policy needs to be installed without 'overloading' dirty variable. Also print warning if we would be clearing read-only volume. (it really shouldn't happen).
2016-12-18 17:05:57 +03:00
Avoid shifting by one number of blocks when clearing dirty cache volume.
validation: check external property is matching Detect if number of external_count is matching referencing devices for external_origin LV.
2016-12-17 23:58:35 +03:00
Extend metadata validation of external origin LV use count.
thin: reload external origin with last thin External origin could be activated as stand-alone device. When the last thin LV is removed, external origin is no longer the external origin and it's layer property was dropped. Ensure dm table is correct by reloading external origin (when it's active).
2016-12-17 23:55:02 +03:00
Fix dm table when the last user of active external origin is removed.
lvs: show status for layer When LV is external origin, show info for LV but status for -layer. So we expose more info to a user as otherwise active external origin is only linear mapping of -real layer. We do the same for i.e. old snaphost origin.
2016-12-17 23:54:51 +03:00
Improve reported lvs status for active external origin volume.
raid: fix activation of tracked image Activation of raid has brough up also splitted image with tracing (without taking lock for this). So when raid is now activate - such image is not put into table (with _rmeta). When user needs such device, just active it.
2016-12-14 23:47:38 +03:00
Fix table load for splitted RAID LV and require explicit activation.
raid: split preserves local exlusive activation
2016-12-14 12:19:25 +03:00
Always active splitted RAID LV exclusively locally.
raid: avoid manipulation of segment status RAID is LV property TODO: only 2 flags are seg->status: PVMOVE & MERGING At least the second one should be soon elimanted as again we merge LV not a segment.
2016-12-13 16:52:06 +03:00
Do not use LV RAID status bit for segment status.
raid: fix activation of tracked image Activation of raid has brough up also splitted image with tracing (without taking lock for this). So when raid is now activate - such image is not put into table (with _rmeta). When user needs such device, just active it.
2016-12-14 23:47:38 +03:00
Check segtype directly instead of checking RAID in segment status.
raid: improve table reload sequence This is another place for 'common' use pattern or reload and activation of deleted devices. (Moving the exclusive activation to _deactivate_and_remove_lvs()). TODO: looks like halve of raid function is reloading just 'origin' - and the other full LV.
2016-12-13 14:31:28 +03:00
Reusing exiting code for raid image removal.
pvmove: fix activation order For proper locking we need to gain lock first for mirror which needs to be deactivated later to be working in cluster.
2016-12-11 16:26:17 +03:00
Fix pvmove leaving -pvmove0 error device in clustered VG.
raid: avoid _ at end of name of extracted metadata LV Do not generate @PREFIX@vg/LV1_rmeta_1_extracted_.
2016-12-10 16:51:00 +03:00
Avoid adding extra '_' at end of raid extracted images or metadata.
raid: optimize clearing of lvs Activate whole list of metadata lvs first before clearing them. (Similar to commit ada5733c5652d456ffa138b0d07e6897824813b0) TODO: make this clearing in a single common function.
2016-12-10 22:53:17 +03:00
Optimize another _rmeta clearing code.
raid: fix delete on clustered vg For clustered VG ensure lock is grabbed first, so later deactivation works. TODO: fix tree to solve device removal automatically.
2016-12-10 22:00:32 +03:00
Fix deactivation of raid orphan devices for clustered VG.
raid: fix raid1 to mirror conversion Fix order of operation when converting raid1 into old mirror. Before any later metadata modification are initiated prepare mirror_log device with all clearing. Then directly convert raid1 into mirror with mirror_log. This convertion now properly see as precommitted metadata new 'mirror' and committed old 'raid' and is able to preload all LVs.
2016-12-10 22:01:05 +03:00
Fix lvconvert raid1 to mirror table reload order.
mirror: add prepare_mirror_log Function prepares new mirror log LV in-sync optionaly. This is useful to have such device ready when converting raid1 to mirror.
2016-12-10 21:54:09 +03:00
Add internal function for separate mirror log preparation.
lvmetad: fix segfault in daemon_reply_simple missing NULL termination
2016-12-10 00:17:53 +03:00
Fix segfault in lvmetad from missing NULL in daemon_reply_simple.
dev_manager: use setup_task_run for mknod Simplify info run for use only for INFO & STATUS. Drop handling MKNODES within _info_run() call and use more advanced _setup_task_run() directly. This allows to further simplify _info_run().
2016-12-02 15:46:47 +03:00
Simplify internal _info_run() and use _setup_task_run() for mknod.
dev_manager: extend setup_task Integrate also query for inactive table and handle dm_task_run() and dm_task_get_info() (thus switching to setup_task_run) Add one exception case for DM_DEVICE_TARGET_MSG. This allows further shortening and simplification of all other users of this function.
2016-12-01 16:56:32 +03:00
Better API for internal function _setup_task_run.
activation: optimize away lv_has_target_type It's actually not needed to call extra lv_has_target_type() to detect snapshot merge is in progress - decode this right during status capturing and save even few extra ioctl calls.
2016-12-05 17:23:18 +03:00
Avoid using lv_has_target_type() call within lv_info_with_seg_status.
activation: lv_info_with_seg_status API change Drop LV from passed API arg - it's always segment being checked. Also use_layer is now in full control of lv_info_with_seg_status(). It decides which device needs to be checked to get 'the most info'. TODO: future version should be able to expose status from
2016-12-05 16:31:25 +03:00
Simplify internal lv_info_with_seg_status API.
activation: lv_info_with_seg_status unify status selection Start moving selection of status taken for a LV into a single place. The logic for showing info & status has been spread over multiple places and were doing too complex decision going agains each other. Unify selection of status of origin & cow scanned device. TODO: in future we want to grab status for LV and layered LV and have both statuses present for display - i.e. when 'old snapshot' of thinLV is takes and there is ongoing merge - at some moment we are not capable to show all needed info.
2016-12-05 12:20:42 +03:00
Decide which status is needed in one place for lv_info_with_seg_status.
activation: improve error handling for status reading When lvm2 wants to see a status, it needs to validate, segment for status reading is matching whan lvm2 expects in metadata. Also ensure status failure will not cause '0' from info reading when actual info was collected properly. Failure in 'status' reading is considered to be a 'log_warn()' event only.
2016-12-01 12:37:03 +03:00
Fix matching of LV segment when checking for it info status.
activation: status check switch to warn When we can't parse status, switch to warning as this is not considered an errornous case. LVS is not supposed to return error status code when device is not what it's been expected to be - but it should be WARNING a user there is something unexpected.
2016-12-02 15:57:52 +03:00
Report log_warn when status cannot be parsed.
lv: always check status type Always validate status type has an expected value, before accessing status struct members.
2016-12-01 12:43:55 +03:00
Test segment type before accessing segment members when checking status.
striped: implement compatible target name Linear is handled by striped target.
2016-12-01 18:09:53 +03:00
Implement compatible target function for stripe segment.
snapshot: reporting uses statusinfo Convert lvs -o lv_merge_failed,lv_snapshot_invalid to use lv_info_and_status function. This makes it equal to attr value showing this info (as they were different since they were derived from different data set and different logic as well). Also saves couple extra ioctl that were needed to obtain this info.
2016-12-01 19:58:06 +03:00
Use status info to report merge failed and snapshot invalid lvs fields.

Version 2.02.168 - 30th November 2016
=====================================
raid: fix sync percent on large RaidLVs Resolves: rhbz1400301
2016-12-01 02:00:02 +03:00
Display correct sync_percent on large RaidLVs
WHATS_NEW: New argument --blackboxsize
2016-12-01 01:40:49 +03:00
lvmdbusd --blackboxsize <n> added, used to override default size of 16
WHATS_NEW: Allow a transiently failed RaidLV to be refreshed
2016-12-01 01:17:21 +03:00
Allow a transiently failed RaidLV to be refreshed
cleanup: use lv_update_and_reload Avoid code duplication and use exiting commonly used lv_update_and_reload() function. There is still one place left where mirror is doing strange double suspend call - needs there more thinking what's wrong with that code.
2016-11-23 12:57:36 +03:00
Use lv_update_and_reload() inside mirror code where it applies.
mirror: preserve MIRRORED status for temporara image When lvconvert adds a new leg - it's doing it free 'temporary' image layer - however this temporary 'internal' mirror is also MIRRORED LV. But the status bit was not properly transfered through layer.
2016-11-23 19:11:26 +03:00
Preserve mirrored status for temporary layered mirrors.
raid: lvconvert uses transient check for raid Also check if the raid status isn't teling us there is something wrong with any raid image device.
2016-11-21 16:54:51 +03:00
Use transient raid check before repairing raid volume.
raid: implement transient status check Take into acount reported state from 'raid' targets. When raid leg is marked with 'D' - take it as missing leg.
2016-11-21 14:43:18 +03:00
Implement transient status check for raid volumes.
dbus: only log msg as debug if lvm2-lvmdbusd unit missing for D-Bus notification Do not emit warning message but only log debug message if lvm2-lvmdbusd.service unit is missing and at the same time we have global/notify_dbus=1 (which is used by default if we configured sources with "--enable-notify-dbus"). We don't want hard dependency between LVM2 and lvmdbusd so it's enough to log only debug message in this case.
2016-11-14 16:46:44 +03:00
Only log msg as debug if lvm2-lvmdbusd unit missing for D-Bus notification.
pre-release
2016-12-01 02:14:34 +03:00
Avoid duplicated underscore in name of extracted LV image.
conf: support zero for missing_stripe_filler Make it easier to replace missing segments with 'zero' returning target - otherwise user would have to create some extra target to provide zeros as /dev/zero can't be used (not a block device). Also break code loop when segment is found and make it an INTERNAL_ERROR where it's missing.
2016-10-18 13:58:22 +03:00
Missing stripe filler now could be also 'zero'.
lvconvert: repair accepts interval and background For mirror and raid we expose --interval and --background on command line (instead of using just always using compiled-in defaults).
2016-10-17 12:16:16 +03:00
lvconvert --repair accepts --interval and --background option.
raid: faster rmeta clearing Instead of clearing multiple rmeta device with sequential activation process and waiting for udev for every _rmeta device separately, activate all _rmeta devices first and then clear them and deactivate afterwards. Also update some tracing messages. When anyhing goes wrong during clearing process, always try to deactivate as much _rmeta devices as possible before fail.
2016-11-08 13:54:28 +03:00
More efficiently prepare _rmeta devices when creating a new raid LV.

Version 2.02.167 - 5th November 2016
====================================
cleanup: log_info to log_error Switch to more appropriate logging level.
2016-10-31 20:03:06 +03:00
Use log_error in regex and sysfs filter to describe reason of failure.
blkdeactivate: deactivate dev stack if dev on top already unmounted If blkdeactivate finds out that the device on top of device stack is already unmounted, it still proceeds with device stack deactivation underneath now. This situation can happen if blkdeactivate is started and the mount point is unmounted in parallel by chance (so when blkdeactivate gets the the actual umount call, the device is not mounted anymore). Before, the blkdeactivate added such device to skip list which caused all the stack underneath to be skipped too on deactivation. Now, we proceed just as if blkdeactivate did the umount itself. For example, in the example below, the vg-lvol0 is mounted on /mnt/test when blkdeactivate is called, but it gets unmounted in parallel later on when blkdeactivate gets to the actual umount call. Before this patch (vg-lvol0 underneath not deactivated): $ blkdeactivate -u Deactivating block devices: [UMOUNT]: unmounting vg-lvol0 (dm-2) mounted on /mnt/test... skipping With this patch applied (vg-lvol0 underneath still deactivated): $ blkdeactivate -u Deactivating block devices: [UMOUNT]: unmounting vg-lvol0 (dm-2) mounted on /mnt/test... already unmounted [LVM]: deactivating Logical Volume vg/lvol0... done
2016-11-01 18:41:30 +03:00
Fix blkdeactivate to deactivate dev stack if dev on top already unmounted.
lvconvert: prevent non-synced raid1 primary leg repair (Automatic) repair may not be allowed during the initial sync of an upconverted linear LV, because the data on the failing, primary leg hasn't been completely synchronized to the N-1 other legs of the raid1 LV (replacing failed legs during repair involves discontinuing access to any replaced legs data, thus preventing data recovery on the primary leg e.g. via dd_rescue). Even though repair would not cause data loss when adding legs to a fully synced raid1 LV, we don't have information yet defining this state yet (e.g. a raid1 LV flag telling the fully synchronized status before any legs were added), hence can't automatically decide to allow to repair. If nonetheless a repair on a non-synced raid1 LVs is intended, the "--force" option has to be provided. Resolves: rhbz1311765
2016-10-28 16:54:27 +03:00
Prevent non-synced raid1 repair unless --force
lvchange/vgchange/lvconvert: prevent raid4 creation/activation/conversion on non-supporting raid targets Check for dm-raid target version with non-standard raid4 mapping expecting the dedicated parity device in the last rather than the first slot and prohibit to create, activate or convert to such LVs from striped/raid0* or vice-versa in order to avoid data corruption. Add related tests to lvconvert-raid-takeover.sh Resolves: rhbz1388962
2016-10-27 12:38:16 +03:00
Prevent raid4 creation/conversion on non-supporting kernels
lvconvert: position dedicated parity device in raid4 conversions porperly On conversions between striped/raid0* and raid4, the kernel expects the dedicated raid4 parity SubLVs in the first segment area rather than in the last it's been allocated to, thus the data mapping ain't proper. Enhance lvconvert (lib/metadata/raid_manip.c) to shift the dedicated parity SubLVs on conversions from striped/raid0* to raid4 and vice-versa. In case of raid0_meta -> raid4 where the MD raid0 personality already has stored RAID array device positions in the superblocks, the MetaLVs have to be cleared so that the kernel doesn't fail validating the array positions after lvm has shifted them up by one. Add more tests to lvconvert-raid-takeover.sh including one to check for mapping flaws by converting a created raid4 with filesystem -> striped and fsck it. Whilst on it: - add missing direct striped -> raid4 conversion to the takeover array to avoid an intermim conversion from striped -> raid0* - clean up the takeover array - allow lvconvert to actually call lv_raid_convert() on all takeover requests in order to check parameters and display messages provided by takeover functions rather than just "...not supported" from within lvconvert - fix a typo Resolves: rhbz1386148
2016-10-21 19:59:59 +03:00
Add direct striped -> raid4 conversion
Fix raid4 parity image pair position on conversions from striped/raid0*
lvconvert: fix error value Seems some error path where not converted to 'new' ECMD return value. Fix them to always 'goto out'. Also drop unneeded 'ret = 0' when ret already is 0.
2016-10-11 12:59:43 +03:00
Fix a few unconverted return code values for some lvconvert error path.
lvconvert: Disable thin pool raid conversion while active. Works if the pool is inactive. Activation code doesn't notice a new raid dependency in on-disk metadata when a thin LV is already active. https://bugzilla.redhat.com/1365286
2016-09-27 20:22:54 +03:00
Disable lvconvert of thin pool to raid while active.
systemd: disable service start rate limiting for lvm2-pvscan@.service We shouldn't be losing pvscans just because of the fact that the underlying device (PV) appears and disappears quickly in the system, otherwise lvmetad may not see the device if it appears again (or it may still keep the device in cache even it's already gone).
2016-09-27 11:47:54 +03:00
Disable systemd service start rate limiting for lvm2-pvscan@.service.

Version 2.02.166 - 26th September 2016
======================================
toolcontext: read all configuration sources when checking config values in lvm2-activation-generator through lighweight toolcontext handler We added lightweight toolcontext handle to avoid useless initialization of some parts of the context and also to avoid problems when using the handle very soon at system boot, like in lvm2-activation-generator through lvm2app interface. However, we missed reading all the other config sources like lvmlocal.conf as well as any tag config - we need to read these too to get the final config value which may be overriden in any of these additional config sources. Currently, we use this lightweight toolcontext handle to read global/use_lvmetad and global/use_lvmpolld config values in lvm2-activation-generator using lvm2app interface (lvm_config_find_bool lvm2app function).
2016-09-23 15:51:15 +03:00
Fix lvm2-activation-generator to read all LVM2 config sources. (2.02.155)
tests: fix raid rebuild tests to work with older target versions Pre 1.9 dm-raid targets status output was racy, which caused the device status chars to be unreliable _during_ synchronization. This shows paritcularly with tiny test devices used. Enhance lvchange-rebuild-raid.sh to not check status chars _during_ synchronization. Just check afterwards.
2016-09-23 00:35:37 +03:00
Fix lvchange-rebuild-raid.sh to cope with older target versions.
config: use config_tree_from_string_without_dup_node_check throughout code to construct metadata trees
2016-09-21 15:59:14 +03:00
Use dm_config_parse_without_dup_node_check() to speedup metadata reading.
lvconvert: fix (automatic) raid repair regression The dm-raid target now rejects device rebuild requests during ongoing resynchronization thus causing 'lvconvert --repair ...' to fail with a kernel error message. This regresses with respect to failing automatic repair via the dmeventd RAID plugin in case raid_fault_policy="allocate" is configured in lvm.conf as well. Previously allowing such repair request required cancelling the resynchronization of any still accessible DataLVs, hence reasoning potential data loss. Patch allows the resynchronization of still accessible DataLVs to finish up by rejecting any 'lvconvert --repair ...'. It enhances the dmeventd RAID plugin to be able to automatically repair by postponing the repair after synchronization ended. More tests are added to lvconvert-rebuild-raid.sh to cover single and multiple DataLV failure cases for the different RAID levels. - resolves: rhbz1371717
2016-09-21 01:38:38 +03:00
Fix lvconvert --repair regression
cache: restore reported origin field Commit 199697accff0658a11420e263c1f85fb74cd39d3 rerouted funtion for priting cache volume origin to lvm2app app function - which however had a bug. So restore the original functionality and print correct LV as cache origin LV.
2016-09-20 15:26:11 +03:00
Fix reported origin lv field for cache volumes. (2.02.133)
snapshots: Fix monitoring to use cow not internal LV.
2016-09-20 04:30:58 +03:00
Always specify snapshot cow LV for monitoring not internal LV. (2.02.165)
thin: fix lvchange of discards and zero flag Reload of thin-pool origin_only is designed to only post messages to a thin-pool. It's not intended to be used for reload of thin-pool table. Fix it by using standard call 'lv_update_and_reload()'.
2016-04-23 22:09:09 +03:00
Fix lvchange --discard|--zero for active thin-pool.
thin: enforce there is some free space in thin pool metadata Unconditionally guard there is at least 1/4 of metadata volume free (<16Mib) or 4MiB - whichever value is smaller. In case there is not enough free space do not let operation proceed and recommend thin-pool metadata resize (in case user has not enabled autoresize, manual 'lvextend --poolmetadatasize' is needed).
2016-09-16 22:50:14 +03:00
Enforce 4MiB or 25% metadata free space for thin pool operations.
thin: report pool as holder when no active thin volume In the case there is no active thin volume, report thin pool as lock holder. This fixed function like lvextend which either expecte lock holder LV is some active thin or 'possibly' inactive thin pool.
2016-09-16 22:47:57 +03:00
Fix lock-holder device for thin pool with inactive thin volumes.
alloc: Use --alloc normal for mirror logs. The existing code doesn't understand that mirror logs should cling to parallel LVs (like extending them) instead of avoiding them. As a quick workaround to avoid lvcreate failures, hard-code --alloc normal for mirror logs even if the rest of the allocation used a stricter policy. https://bugzilla.redhat.com/show_bug.cgi?id=1376532
2016-09-16 04:11:58 +03:00
Use --alloc normal for mirror logs even if the mimages were stricter.
lvmdump: Use O_DIRECT to gather metadata.
2016-09-15 15:59:52 +03:00
Use O_DIRECT to gather metadata in lvmdump.
pre-release
2016-09-26 16:20:08 +03:00
Ignore creation_time when checking for matching metadata for lvmetad.
activation: dso always defined for monitoring query Ensure 'dso' has always a defined (NULL) value, and also ensure NULL 'dso' is not dereferenced.
2016-09-12 17:37:31 +03:00
Fix possible NULL pointer derefence when checking for monitoring.
man: add lvmreport man page
2016-09-12 14:54:37 +03:00
Add lvmreport(7) man page.
man: Only install lvmraid when needed.
2016-09-12 15:03:09 +03:00
Don't install lvmraid(7) man page when raid excluded. (2.02.165)
cache: fix reporting of dirty cache When cache has zero used blocks it's been wrongly reported as 100.00% dirty. Fix it and report 0.00.
2016-09-09 21:45:37 +03:00
Report 0% as dirty (copy%) for cache without any used block.
lvm2app: fix cache percantage reporting In lvm2app we were always returning dirty (copy%) value. Return properly data & metadata usage values.
2016-09-09 15:25:53 +03:00
Fix lvm2api reporting of cache data and metadata percent.
cache: report metadata percentage Reinstantiate reporting of metadata percent usage for cache volumes. Also show the same percentage with hidden cache-pool LV. This regression was caused by optimization for a single-ioctl in 2.02.155.
2016-09-09 15:24:49 +03:00
Restore reporting of metadata usage for cache volumes (2.02.155).
cache: scrubbing for cache origin LV - Bug 1169495 Allow RAID scrubbing on cache origin sub-LV This patch adds the ability to perform RAID scrubbing on the cache origin sub-LV (https://bugzilla.redhat.com/1169495). Cache origin operations are restricted to non-clustered RAID LVs until there can be further testing in a cluster (even for exclusive activation). User can either specify directly _corig LV or he can specify cache LV and operation --syncation is passed ONLY to _corig LV. If users wants to manipulation with cache-pool devices - he needs to specify this object name. Signed-off-by: Jonathan Brassow <jbrassow@redhat.com>
2016-09-06 17:29:14 +03:00
Support raid scrubbing on cache origin LV.

refactor: move and rename _dev_is_mpath_component in lvmetad.c to udev_dev_is_mpath_component in dev-type.c
2016-09-05 13:13:10 +03:00
Use udev db to check for mpath components before running pvscan for lvmetad.
lvmdump: use lsblk -s and lsblk -O in lvmdump only if these options are supported The lsblk is just a nice helper here - it's not crucial for lvmdump so do best effort here and use the most we can from current version of lsblk that is installed on system. The lsblk -s option was added a bit later after lsblk introduction and lsblk -O support even more later - so if these are not available, use only pure lsblk output without any extras.
2016-08-30 16:33:50 +03:00
Use lsblk -s and lsblk -O in lvmdump only if these options are supported.
raid10: Fix #stripes in lvcreate msg when too many.
2016-08-30 14:04:23 +03:00
Fix number of stripes shown in lvcreate raid10 message when too many.
pre-release
2016-09-07 04:25:51 +03:00
Change lvmdbusd to use new lvm shell facilities.
cache: do not monitor cache-pool Avoid monitoring of activated cache-pool - where the only purpose ATM is to clear metadata volume which is actually activate in place of cache-pool name (using public LV name). Since VG lock is held across whole clear operation, dmeventd cannot be used anyway - however in case of appliction crash we may leave unmonitored device. In future we may provide better mechanism as the current name replacemnet is creating 'uncommon' table setups in case the metadata LV is more complex type like raid (needs some futher thinking about error path results). Another point to think about is the fact we should not clear device while holding lock (i.e. dmeventd mirror repair cannot work in cases like this).
2016-08-24 11:05:09 +03:00
Do not monitor cache-pool metadata when LV is just being cleared.
cache: introduce cache_pool_max_chunks Introduce 'hard limit' for max number of cache chunks. When cache target operates with too many chunks (>10e6). When user is aware of related possible troubles he may increase the limit in lvm.conf. Also verbosely inform user about possible solution. Code works for both lvcreate and lvconvert. Lvconvert fully supports change of chunk_size when caching LV (and validates for compatible settings).
2016-08-24 11:16:01 +03:00
Add allocation/cache_pool_max_chunks to prevent misuse of cache target.
lvconvert: Fix --splitmirrors segfault with incorrect PV. Commit 9ee071705b2c35e1132f39f5731861c831a1bb6b misunderstood integer promotion, but it's simpler to detect -1 more directly.
2016-08-26 03:21:01 +03:00
Give error not segfault in lvconvert --splitmirrors when PV lies outside LV.
conf: fix typo in report/columns_as_rows config option name recognition Commit e947c362dd0ae1da2d76925fe6b38244c5f46d25 introduced config_settings.h file for central place to store all definitions for config options. By mistake, it used report/colums_as_rows instead of report/columns_as_rows (missing "n" in "columns").
2016-08-25 15:53:32 +03:00
Fix typo in report/columns_as_rows config option name recognition (2.02.99).
alloc: Avoid PV tags too when avoiding parallel PV allocation. Also add debug messages for parallel PVs.
2016-08-24 21:37:50 +03:00
Avoid PV tags when checking allocation against parallel PVs.
alloc: Move _log_parallel_areas.
2016-08-24 17:39:56 +03:00
Disallow mirror conversions of raid10 volumes.
dmeventd: Fix unmonitoring when segtype changes. When the segment type is being changed, unmonitoring an LV requires the existing dso to be specified as a parameter, not the new one.
2016-08-23 04:24:30 +03:00
Fix dmeventd unmonitoring when segment type (and dso) changes.
raid: Don't monitor raid0 or raid0_meta LVs.
2016-08-20 04:14:33 +03:00
Don't allow lvconvert --repair on raid0 devices or attempt to monitor them.
lvcreate: No longer adjust --stripes for raid types. If the number of stripes requested is incompatible with the requested type of raid, give an error instead of adjusting it. If no stripes argument is supplied, continue to use an appropriate default.
2016-08-19 16:19:51 +03:00
No longer adjust incorrect number of raid stripes supplied to lvcreate.
lib: Move lcm and gcd to lib/misc for wider use.

2016-08-15 21:38:45 +03:00
Suppress some unnecessary --stripesize parameter warnings.
pvmove: prohibit non-resilient collocation of RAID SubLVs 'pvmove -n name pv1 pv2' allows to collocate multiple RAID SubLVs on pv2 (e.g. results in collocated raidlv_rimage_0 and raidlv_rimage_1), thus causing loss of resilence and/or performance of the RaidLV. Fix this pvmove flaw leading to potential data loss in case of PV failure by preventing any SubLVs from collocation on any PVs of the RaidLV. Still allow to collocate any DataLVs of a RaidLV with their sibling MetaLVs and vice-versa though (e.g. raidlv_rmeta_0 on pv1 may still be moved to pv2 already holding raidlv_rimage_0). Because access to the top-level RaidLV name is needed, promote local _top_level_lv_name() from raid_manip.c to global top_level_lv_name(). - resolves rhbz1202497

WHATS_NEW: reject --nosync option for RAID6 LVs in lvcreate
2016-08-08 17:00:49 +03:00
Reject --nosync option for RAID6 LVs in lvcreate.
lvmcmdline: do not refresh whole cmd context if profile dropped after processing LVM cmd We don't need to refresh whole cmd context if we drop profile after processing LVM command - just like we don't refresh cmd context when we're applying the profile. It's because profiles contain only safe subset of settings which do not require complete cmd context refresh. This patch calls process_profilable_config instead of refresh_toolcontext if there was profile applied for the LVM command only, not --config which requires toolcontext refresh. The process_profilable_config just sets proper values based on values of profilable settings, but it does not do complete reinitialization of various parts (e.g. filters, logging etc.).
2016-08-08 12:57:13 +03:00
Do not refresh whole cmd context if profile dropped after processing LVM cmd.
lvconvert: Support raid0<->raid4 and mirror<->raid1. Only simple takeover cases so far.
2016-08-07 02:56:08 +03:00
Support straightforward lvconvert between striped and raid4 LVs.
Support straightforward lvconvert between raid1 and mirror LVs.
raid: Report supported lvconvert conversions if invalid.
2016-08-07 02:30:26 +03:00
Report supported conversions when asked for unsupported raid lvconvert.
WHATS_NEW: fixup order
2016-08-05 17:31:46 +03:00
Add "--rebuild PV" option to lvchange to allow for PV selective rebuilds.
lvconvert: Preserve mirror region size with --repair.
2016-08-02 21:50:04 +03:00
Preserve existing mirror region size when using --repair.
lvconvert: Forbid stripe parameters with --repair.
2016-08-02 17:57:45 +03:00
Forbid stripe parameters with lvconvert --repair.
tools: Unify stripesize parameter validation. Move it all into get_stripe_params(). Some code paths missed --stripesize checks. E.g. lvcreate --type raid4 -i1
2016-07-30 04:05:50 +03:00
Unify stripe size validation into get_stripe_params to catch missing cases.
lvconvert: Rearrange code that decides segtype.
2016-07-30 02:22:13 +03:00
Further lvconvert validation logic refactoring.

Version 2.02.162 - 28th July 2016
post-release
2016-07-16 00:02:58 +03:00
=================================
pre-release
2016-07-28 20:35:32 +03:00
Extend vg_validate also to check raid configurations thoroughly.
lvconvert: support --zero for full cache pool conversion. Add matching support for -Z option also we doing full conversion to cache-pool. Extending coversion message to show which pool type is created and whether the metadata will be wiped or remain unmodified.
2016-07-27 17:14:47 +03:00
Support lvconvert -Zn also when doing full cache pool conversion.
lvconvert: suppress zeroing warning when converting to thin When volume was lvconvert-ed to a thin-volume with external origin, then in case thin-pool was in non-zeroing mode it's been printing WARNING about not zeroing thin volume - but this is wanted and expected - so nothing to warn about. So in this particular use case WARNING needs to be suppressed. Adding parameter support for lvcreate_params. So now lvconvert creates 'normal thin LV' in read-only mode (so any read will 'return 0' for a moment) then deactivate regular thin LV and reacreate in 'final R/RW' mode thin LV with external origin and activate again.
2016-07-27 14:36:25 +03:00
Suppress not zeroing warn when converting to thin LV for non-zeroing tpool.
metadata: fix automatic updates of PV extension headers to newest version Before, the automatic update from older to newer version of PV extension header happened within vg_write call. This may have caused problems under some circumnstances where there's a code in between vg_write and vg_commit which may have failed. In such situation, we reverted precommitted metadata and put back the state to working version of VG metadata. However, we don't have revert for PV write operation at the moment. So if we updated PV headers already and we reverted vg_write due to failure in subsequent code (before vg_commit), we ended up with lost VG metadata (because old metadata pointers got reset by the PV write operation). To minimize problematic situations here, we should put vg_write and vg_commit that is done after PV header rewrites as close to each other as possible. This patch moves the automatic PV header rewrite for new extension header part from vg_write to _vg_read where it's done the same way as we do any other VG repairs if detected during VG read operation (under VG write lock).
2016-07-26 16:46:36 +03:00
Fix automatic updates of PV extension headers to newest version.
lvconvert: --trackchanges requires --splitmirrors 1
2016-07-25 23:15:25 +03:00
Improve lvconvert --trackchanges validation to require --splitmirrors 1.
man: add note about 'lastlog' built-in command
2016-07-25 16:05:08 +03:00
Add note about lastlog built-in command to lvm man page.
segtype: Fix unrecognised flag message. Show in hex not decimal.
2016-07-25 14:56:25 +03:00
Fix unrecognised segtype flag message.
lvconvert: tune cache-pool zeroing Follow-up to 27a767d5e8cedf9cac31eb3562cf8fdd4aa88b7c. Tunning behavior in a way we always prompt when option --zero is NOT specified. Without -Z lvm expects user wants to 'reset' cache-pool metadata (they could have been splitted from some cached LV) If user doesn't want to zero metadata he needs to specify -Zn. User may also avoid prompting for zeroing by using -Zy for cache-pool (basically equals using --yes without -Z being given) (unlike full convert case, there is no cache-pool being converted, so there is not 'uncoditional' prompt in this case).
2016-07-23 22:17:56 +03:00
lvconvert not clears cache pool metadata ONLY with -Zn.
pre-release
2016-07-28 20:35:32 +03:00
Add allocation/raid_stripe_all_devices to reinstate previous behaviour.
Create raid stripes across fixed small numbers of PVs instead of all PVs.
lvconvert: enable work with partial LVs Fix printed message and enable handling of missing PVs.
2016-07-19 18:11:57 +03:00
Enabled lvconvert --uncache to work with partial VG.

raid0: Add raid0_meta segment type.
2016-07-02 00:20:54 +03:00
Add raid0_meta segment type that provides metadata space for raid conversions.
thin: fix link validation for unused thin-pool This patch fixes link validation for used thin-pool. Udev rules correctly creates symlinks only for unused new thin-pool. Such thin-pool can be used by foreing apps (like Docker) thus has /dev/vg/lv link. However when thin-pool becomes used by thinLV - this link is no longer exposed to user - but internal verfication missed this and caused messages like this to be printed upon 'vgchange -ay': The link /dev/vg/pool should have been created by udev but it was not found. Falling back to direct link creation. And same with 'vgchange -an': The link /dev/vg/pool should have been removed by udev but it is still present. Falling back to direct link removal. This patch ensures only unused thin-pool has this link.
2016-06-30 16:54:27 +03:00
Fix created link for a used pool for vgmknode.
macros: Use is_power_of_2.

Version 2.02.158 - 25th June 2016
post-release
2016-06-17 15:57:33 +03:00
=================================
WHATS_NEW: add recent changes
2016-06-27 19:10:58 +03:00
Add a more efficient native vgimportclone command to replace the script.
Make lvmlockd always attempt to connect to lvmetad if no connection exists.
Let lvmetad handle new connections after shutdown signal.
Disable lvmetad when vgcfgrestore begins and enable it again after.
Make pvscan do activation if lvmetad is configured but not running.
Fix rescanning the PVs for a single VG when using lvmetad.
lvresize: support more resized LVs Add code to support more LVs to be resized through a same code path using a single lvresize_params struct. (Now it's used for thin-pool metadata resize, next user will be snapshot virtual resize). Update code to adjust percent amount resize for use_policies. Properly activate inactive thin-pool in case of any pool resize as the command should not 'deffer' this operation to next activation.
2016-06-23 00:32:35 +03:00
Pool metadata lvresize uses now same code as resize of normal volume.
monitoring: preserve monitoring status during update Ignore monitoring during whole update (suspend/resume) of thin-pool.
2016-06-23 00:21:27 +03:00
Preserve monitoring status when updating thin-pool metadata.
Revert "locking: trace errors from dir creation" This reverts commit fa69ed0bc845df3d2c7ae68d03cdd4a3dec339d8. This code sometimes expects to be presented with a read-only filesystem (during some boot sequences for example) and copes appropriately with this and it should not lead to expected error messages that might cause unnecessary alarm.
2016-06-23 23:31:49 +03:00
Return 0 (inactive) when status cannot be queried in _lv_active().
activation: switch to warning Since this function does not have a way to return error use correct reporting level as warning.
2016-06-21 16:16:03 +03:00
Switch to log_warn() for failing activation status query.
pre-release
2016-06-25 22:35:14 +03:00
Replace vgimportclone script with binary.
While lvmetad is shutting down, continue handling all connections cleanly.
lvconvert: Refactor argument handling code. Begin disentangling the different lvconvert modes of operation from each other.
2016-06-22 20:40:22 +03:00
Refactor lvconvert argument handling code.
pre-release
2016-06-25 22:35:14 +03:00
Notify lvmetad when vgcfgrestore changes VG metadata.
report: add --logonly arg to report only log for a command
2016-06-15 14:35:27 +03:00
Add --logonly option to report only cmd log for a command, not other reports.
conf: add log/command_log_selection config setting
2016-06-14 14:25:03 +03:00
Add log/command_log_selection to configure default selection used on cmd log.
log: use separate 'orphan' report object type for orphan VGs
2016-06-14 14:21:53 +03:00
Use 'orphan' object type in cmd log for groups to collect PVs not yet in VGs.
tools: add 'lvm lastlog' command for interactive query and display of last command's log If we're running in lvm shell, we can keep last command's log report for further query with possible different selection criteria for easy log lookup.
2016-05-20 16:30:58 +03:00
Add lvm lastlog command for query and display of last cmd's log in lvm shell.
log: annotate processing code with report_current_object_cmdlog
2016-05-23 16:27:09 +03:00
Report per-object return codes via cmd log while processing multiple objects.
log: annotate processing code with log_set_report_{context,object_type,id_and_name}
2016-05-20 14:26:02 +03:00
Annotate processing code with log report hooks for per-object command log.
log: also pass log_print through report and add log_print_bypass_report for use in libdm-report for direct print without report log_print is used during cmd line processing to log the result of the operation (e.g. "Volume group vg successfully changed" and similar). We don't want output from log_print to be interleaved with current reports from group where log is reported as well. Also, the information printed by log_print belongs to the log report too, so it should be rerouted to log report if it's set. Since the code in libdm-report which is responsible for doing the report output uses log_print too, we need to use a different kind of log_print which bypasses any log report currently used for logging (...simply, we can't call log_print to output the log report itself which in turn would again reroute to report - the report would never get on output this way).
2016-05-19 13:19:48 +03:00
Also pass common printed messages (besides warnings and errors) to log report.
log: log warnings and errors via report if set; add log_set_report* fns This patch adds structures and functions to reroute error and warning logs to log report, if it's set. There are 5 new functions: - log_set_report Set log report where logging will be rerouted. - log_set_report_context Set context globally so any report_cmdlog call will use it. - log_set_report_object_type Set object type globally so any report_cmdlog call will use it. - log_set_report_object_name_and_id Set object ID and name globally so any report_cmdlog call will use it. - log_set_report_object_group_and_group_id Set object group ID and name globally so any report_cmdlog call will use it. These functions will be called during LVM command processing so any logs which are rerouted to log report contain proper information about current processing state.
2016-05-03 12:46:52 +03:00
Log warnings and errors via report during cmd processing if this is enabled.
toollib: make it possible to also process internal VGs, add 'include_internal' switch to process_each_vg fn The lvm fullreport works per VG and as such, the vg, lv, pv, seg and pvseg subreport is done for each VG. However, if the PV is not part of any VG yet, we still want to display pv and pvseg subreports for these "orphan" PVs - so enable this for lvm fullreport's process_each_vg call.
2016-05-03 12:46:28 +03:00
Make it possible to iterate over internal 'orphan' VGs in process_each_vg fn.
report: recognize selection (-S|--select) for each subreport; make -S|--select groupable
2016-05-26 16:20:27 +03:00
Make -S|--select option groupable that allows this option to be repeated.
report: recognize list of keys to sort report by (-O|--sort) for each subreport; make -O|--sort groupable
2016-05-26 16:12:38 +03:00
Make -O|--sort option groupable that allows this option to be repeated.
args: add --configreport arg
2016-06-16 16:49:18 +03:00
Add --configreport option to select report for which next options are applied.
args: add priorities for grouping args Groupable args (the ones marked with ARG_GROUPABLE flag) start a new group of args if: - this is the first time we hit such a groupable arg, - or if non-countable arg is repeated. However, there may be cases where we want to give priorities when forming groups and hence force new group creation if we hit an arg with higher grouping priority. For example, let's assume (for now) hypothetical sequence of args used: lvs -o lv_name --configreport log -o log_type --configreport lv -o +vg_name Without giving any priorites, we end up with: lvs -o lv_name --configreport log -o log_type --configreport lv -o +vg_name | | | | | | \__________GROUP1___________/ \________GROUP2___________/ \_GROUP3_/ This is because we hit "-o" as the first groupable arg. The --configreport, even though it's groupable too, it falls into the previous "-o" group. While we may need to give priority to the --configreport arg that should always start a new group in this scenario instead: lvs -o lv_name --configreport log -o log_type --configreport lv -o +vg_name | | | | | | \_GROUP1_/ \_________GROUP2___________/ \_________GROUP3__________/ So here "-o" started a new group but since "--configreport" has higher priority than "-o", it starts fresh new group now and hence the rest of the command line's args are grouped by --configreport now.
2016-06-17 12:03:14 +03:00
Add support for priorities on grouping command arguments.
conf: add report/{vgs,pvs,lvs,pvsegs,segs}_{cols,sort}_full config settings
2016-06-14 13:38:40 +03:00
Add report/{pvs,vgs,lvs,pvsegs,segs}_{cols,sort}_full to lvm.conf.
commands: report: add lvm fullreport command lvm fullreport executes 5 subreports (vg, pv, lv, pvseg, seg) per each VG (and so taking one VG lock each time) within one command which makes it easier to produce full report about LVM entities. Since all 5 subreports for a VG are done under a VG lock, the output is more consistent mainly in cases where LVM entities may be changed in parallel.
2016-05-03 12:18:16 +03:00
Add lvm fullreport command for joined PV, VG, LV and segment report per VG.
toollib: add report_group and log_rh to processing_handle and initialize cmd processing log report Wire up report group creation with log report in struct processing_handle and call report_format_init during processing handle initialization (init_processing_handle fn) and destroy it while destroing processing handle (destroy_processing_handle fn). This way, all the LVM command processing using processing handle has access to log report via which the current command log can be reported as items are processed.
2016-05-23 11:16:29 +03:00
Integrate report group handling and cmd log report into cmd processing code.
conf: add log/report_command_log config setting
2016-06-14 12:58:01 +03:00
Add log/report_command_log to lvm.conf to enable or disable cmd log report.
conf: add report/output_format config setting New report/output_format configuration sets the output format used for all LVM commands globally. Currently, there are 2 formats recognized: - basic (the classical basic output with columns and rows, used by default) - json (output is in json format)
2016-05-24 13:05:42 +03:00
Add log/report_output_format to lvm.conf for default report output format.
toollib: add report_format_init fn to create report group and to create/add log report handle Add new --reportformat option and new report_format_init function that checks this option and creates new report group accordingly, also preparing log report handle and adding it to the report group just created.
2016-05-02 15:22:02 +03:00
Recognize --reportformat {basic|json} option to select report output format.
conf: add log/command_log_{sort,cols} config settings
2016-06-14 14:10:29 +03:00
Add log/command_log_{sort,cols} to lvm.conf to configure command log report.
report: add CMDLOG report type This is a preparation for new CMDLOG report type which is going to be used for reporting LVM command log. The new report type introduces several new fields (log_seq_num, log_type, log_context, log_object_type, log_object_group, log_object_id, object_name, log_message, log_errno, log_ret_code) as well as new configuration settings to set this report type (report/command_log_sort and report/command_log_cols lvm.conf settings). This patch also introduces internal report_cmdlog helper function which is a wrapper over dm_report_object to report command log via CMDLOG report type and which is going to be used throughout the code to report the log items.
2016-05-10 16:15:48 +03:00
Add log_object_{type,name,id,group,group_id} fields to cmd log.
Add log_{seq_num,type,context,message,errno,ret_code} fields to cmd log.
Add CMDLOG report type - a separate report type for command logging.

2016-06-03 13:38:46 +03:00
Fix compilation error when building with configure --disable-devmapper.
lvmconfig: fix lvmconfig --type diff to display complete diff if config cascade used If configuration consists of several sources in config cascade ("config cascade" defined in man lvmconfig(8)), lvmconfig displayed only difference from defaults of the topmost config in the cascade. Fix lvmconfig to display complete difference, considering all the configuration in the cascade. For example, before this patch: (use_lvmetad=0 set in lvm.conf which differs from defaults) $ lvmconfig --type diff global { use_lvmetad=0 } (compact_output=1 set on cmd line) $ lvmconfig --type diff --config report/compact_output=1 report { compact_output=1 } (headings=0 set in profile) $ lvmconfig --type diff --commandprofile test report { headings=0 } (difference in topmost configuration source is displayed) $ lvmconfig --type diff --commandprofile test --config report/compact_output=1 report { compact_output=1 } With this patch applied (the config cascade is merged before looking for difference from defaults in configuration): $ lvmconfig --type diff global { use_lvmetad=0 } $ lvmconfig --type diff --config report/compact_output=1 report { compact_output=1 } global { use_lvmetad=0 } $ lvmconfig --type diff --profile test report { headings=0 } global { use_lvmetad=0 } $ lvmconfig --type diff --profile test --config report/compact_output=1 report { headings=0 compact_output=1 } global { use_lvmetad=0 }
2016-06-02 14:41:55 +03:00
Fix lvmconfig --type diff to display complete diff if config cascade used.
devices: handle partscan loop devices Treat loop device created with 'losetup -P' as regular partitioned device - so if it has partition table, prevent its usage in commands like 'pvcreate'. Before 'pvcreate /dev/loop0' could have erased and formated as PV, after this patch, device is filtered out and cannot be used.
2016-06-01 17:39:47 +03:00
Automatically filter out partitioned loop devices with partscan (losetup -P).
report: fix lvm devtypes internal error if -S is used with field name from pvs/vgs/lvs Before this fix, when reporting 'lvm devtypes', the report was initialized with incorrect reserved values - the ones used for pvs/vgs/lvs report were used instead of NULL value (because devtypes doesn't have any reserved values). For example, trying to (incorrectly) use lv_name for the -S|--select with lvm devtypes which doesn't have this field at all: Before this patch (internal error issued): $ lvm devtypes -S 'lv_name=lvol0' Internal error: _check_reserved_values_supported: field-specific reserved value of type 0x0 for field not supported Internal error: dm_report_init_with_selection: trying to register unsupported reserved value type, skipping report selection DevType MaxParts Description aoe 16 ATA over Ethernet ataraid 16 ATA Raid bcache 1 bcache block device cache ... With this patch applied (correct error displayed about unrecognized selection field): $ lvm devtypes -S 'lv_name=lvol0' Device Types Fields ------------------- devtype_name - Name of Device Type exactly as it appears in /proc/devices.

Fix lvm devtypes internal error if -S used with field name from pvs/vgs/lvs.
report: convert more options to use single status Convert fields into using a single status ioctl call per LV. This is a bit tricky since when there are more complicated stacks, at this moment its undefined which values should be shown. It's clear we need to cache more then single ioctl per LV, but also we need to define more explicitely relation between reported values for snapshots. This patch is not a final state, rather a transitional step. It should not be giving more 'worst' values then previous many-ioctl-calls-per-lv solution.
2016-05-25 17:26:10 +03:00
When reporting Data%,Snap%,Meta%,Cpy%Sync use single ioctl per LV.
lv: introduce lvseg_percent_with_info_and_seg_status Add function to obtain percentage value for cache lv_seg_status. This API is rather evolving 'middle' step as the ultimate goal is segment API fuctionality. But first we need to be clear at reporting level which values are needed to be reported for which LVs and segments.
2016-05-25 17:18:38 +03:00
Add lvseg_percent_with_info_and_seg_status() for percent retrieval.
lvstatus: enhance seg_status to handle snapshot Add more code to properly store status for snapshot segment maintaining lvm2 fiction of COW and snapshot internal volumes. The key issue here is however not though-through reporting logic - as there is no single answer for whole line state. It not counting with layer and we may need few more ioctl to cover all reporting needs depending upon what is actually needed. In reality we need to 'cache' more ioctl status queries for individual LVs and their segments (so they checked at most once). The other 'hard' topic for conversion is mirror segment handling. Also we definitelly need to relocate some logic into segment's methods, yet it might be complex as we have not clear border between targets. TODO: define more clearly how are reporting fields defined in case we 'stack' volumes like - cache of stacked thin LV snapshot origin.
2016-05-25 17:14:46 +03:00
Enhance internal seg_status handling to understand snapshots better.
refresh: call resume after failing suspend lv_refresh_suspend_resume() has escaped with fail ret code after failing suspend and could have left many volumes in suspend state. So always unconditionally call resume also when suspend has failed.
2016-05-20 14:20:54 +03:00
When refresh failed in suspend, call resume upon error path.
cache: enhance lv_cache_wait_for_clean Handle passthrough mode when checking cache mode state explicitely.
2016-05-27 15:19:29 +03:00
Support passthrough cache mode when waiting for clean cache.
cache: call status only on cache pool in use Check show cache status only for cache pool in use.
2016-05-24 16:19:01 +03:00
Check cache status only for 'in-use' cache pools.
setup_task: add with_flush To get better control when flushing is used add extra arg when setting up dm task. By default now check dm device status without flush. (At this moment this should effect only thin and cache volumes). Also switch dev_manager_thin_pool_status() to use more readable 'flush' parameter instead of 'no_flush'.
2016-05-27 14:45:47 +03:00
Extend setup_task() to preset flushing for dm_task object.
snapshot: check merging_cow is cow Check first the LV is cow before even checking it's a merging COW. Note: previosly merging_cow was also merging origin, so without this explicit check it used to return '1' also when passed LV has been merging origin.
2016-05-27 14:49:30 +03:00
When checking LV is a merging COW, validate its a COW LV first.
report: fix report copy_percent value When mirror/raid called copy_percent function to return, when 100% was supposed to be returned, wrong float 100.0 value could have been reported back instead of dm_percent_t DM_PERCENT_100. There is broken API somewhere, since the function here rely on actively being modifid VG content even when doing 'lvs' operation. (extents_copies)
2016-05-27 14:48:30 +03:00
Correcting value in copy_percent() for 100%.
WHATS_NEW: include recent changes

2016-05-23 18:46:38 +03:00
Add basic support for --type raid0 using md.
lvchange: allow change of cache mode Add support for active cache LV. Handle --cachemode args validation during command line processing. Rework some lvm2 internal to use lvm2 defined CACHE_MODE enums indepently on libdm defines and use enum around the code instead of passing and comparing strings.
2016-04-25 14:39:30 +03:00
Add support for lvchange --cachemode for cached LV.

WHATS_NEW: duplicate PVs
2016-05-06 17:30:01 +03:00
Change warning messages related to duplicate PVs.
A named device is always processed itself, not switched for a duplicate.
Add PV attr "d" and report field "duplicate" for duplicate PVs.
Add config setting to disallow VG changes when duplicate PVs exist.
Use device size and active LVs to choose the preferred duplicate PV.
Disable lvmetad when duplicate PVs are seen.
lvcreate: improve --chunksize support for cached volume. Support parsing --chunksize option also when converting. Now user can use cache pool created with i.e. 32K chunksize, while in caching user can select 512K blocks. Tool is supposed to validate cache metadata size is big enough to support such chunk size. Otherwise error is shown.
2016-05-05 22:34:21 +03:00
Support --chunksize option also when caching LV when possible.
cleanup: gather version info with single check As we already collect version info anyway, allow to use it through a single call (can makes logs shorter and saves ioctl).

==================================
raid: Use inherited tags when wiping rmeta. If there's an activation volume_filter, it might not be possible to activate the rmeta LVs to wipe them. At least inherit any LV tags from the parent LV while attempting this.
2016-04-29 21:49:21 +03:00
Use any inherited tags when wiping metadata sub LVs to ensure activation.
datastruct: Add str_list_wipe.
2016-04-29 21:47:15 +03:00
Add str_list_wipe.
lvchange: always check for sigint Check sigint() state during process_each_lv.
2016-04-25 14:44:42 +03:00
Improve support for interrupting procesing of volumes during lvchange.
lvchange: fix return code We already opened VG for this - so not an invalid cmdline.
2016-04-25 14:40:26 +03:00
Use failed command return code when lvchanging read-only volume.
thin: zero and transaction_id also with thin volumes Show trasaction_id when thin volume was created. Also show zeroing state of thin-pool with thin volume (so user doesn't need to lookup thin-pool).
2016-04-23 22:08:46 +03:00
Show creation transaction_id and zeroing state of pool with thin volume.
cache: with cache target 1.9 mq is alias to smq Avoid useless check for mq policy, it's loaded as smq and aliased.
2016-04-26 22:43:41 +03:00
Stop checking for dm_cache_mq policy with cache target 1.9 (alias to smq).
modprobe: check /sys/module entry first Before executing modprobe for given module name, just check if the module is not already present in /sys/module. Useful when checking dm-cache-policy modules as we do not having matching interface like for targets.
2016-04-26 22:41:04 +03:00
Check first /sys/module/dm_* dir existance before using modprobe.
udev: rules: remove mpath from 10-dm.rules, superseded by 11-dm-mpath.rules (mpath>=0.6.0) Multipath 0.6.0 contains new 11-dm-mpath.rules which supersede the rule that was in 10-dm.rules. The 11-dm-mpath.rules are also more complete, fixing several other issues. Using the new 11-dm-mpath.rules from multipath-tools >= 0.6.0 is strongly recommended for proper DM multipath functionality!

2016-04-21 21:19:24 +03:00
Fix error path after reusing of _setup_task (2.02.150).
coverity: fix memory access Commit 52e0d0db4460d90172e9bd45b9ef30e7f4f75ae7 introduced regression as code may access buf[0 - 1]. Reorder code to first remove '\n' and then check buffer size for empty.
2016-04-21 21:21:59 +03:00

WHATS_NEW: disable lvmetad for lvm1
2016-04-22 00:40:44 +03:00
Disable lvmetad when lvm1 metadata is seen, so commands revert to scanning.
activate: Hide errors when snapshot merge delayed.
2016-04-22 00:14:10 +03:00
Suppress errors when snapshot merge gets delayed because volume is in use.
display: Avoid internal snapshot LV names in msgs. vg/snapshotN should not appear anywhere. No code should be showing this, but it was noticed in some logs last week and we can deal with it in display_lvname().
2016-04-21 02:30:17 +03:00
Avoid internal snapshot LV names in messages.
configure: detect for /var/lock dir Detecs systems with /run/lock dir and use such path directly instead of /var/lock.
2016-04-21 00:15:00 +03:00
Autodetect and use /run/lock dir when available instead of /var/lock.
lvchange: improve refresh for merging thin volume When running lvchange --refresh on merging thin volume, try to deactivate snapshot thinLV in case it's preventing startup of merge process.
2016-04-18 23:44:30 +03:00
lvchange --refresh for merging thin origin will retry to deactivate snapshot.
thin: check runtime table line for merging To recognize in runtime if we are merging or not to make consistent decision between suspend and resume add function to parse thin table line when add merging thin device to the table.
2016-04-17 15:51:48 +03:00
Recognize in-progress snapshot merge for thin volumes from dm table.
activate: Improve snapshot merge initiation A snapshot merge into its origin cannot be initiated while the devices are in use. If there is outside interference (such as from udev), the suspend (preload) and resume stages can reach conflicting decisions about whether or not to proceed. Try to make the logic more robust by checking the inactive or live table during resume. (This is still not perfect.)
2016-04-15 04:21:27 +03:00
Avoid deciding to initiate a pending snapshot merge during resume.
WHATS_NEW for lvmetad scanning changes
2016-04-15 00:55:34 +03:00
Improve retrying lvmetad requests while lvmetad is being updated.
Read devices instead of using the lvmetad cache if rescan fails.
Move lvmetad token/filter check and device rescan to the start of commands.
snapshot: Don't deactivate fictional snapshot LV. Commit 971ab733b74e0ffecc3f9f60af48628cd3fba1db ("thin: activation of merging thin snapshot") also added an incorrect deactivation attempt for non-thin LVs: find_snapshot(lv)->lv is not designed to be activated and any attempt to deactivate it is incorrect.
2016-04-14 22:48:28 +03:00
Don't try deactivating fictional internal LV before snapshot merge. (2.02.105)
devcache: do not insert devices without device node When not obtaining device from udev, we are doing deep devdir scan, and at the same time we try to insert everything what /sys/dev/block knows about. However in case lvm2 is configured to use nonstardard devdir this way it will see (and scan) devices from a real system. lvm2 test suite is using its own test devdir with its own device nodes. To avoid touching real /dev devices, validate the device node exist in give dir and do not insert such device into a cache. With obtain list from udev this patch has no effect (the normal user path).
2016-04-11 11:08:16 +03:00
When not obtaining devs from udev, check they exist before caching them.
devcache: index devices also without udev We have _insert_dirs() for udev and non-udev compilation. Compiling without udev missed to call dev_cache_index_devs(). Move the call after _insert_dirs() call so both compilation gets it.
2016-04-11 11:23:16 +03:00
Detect device mismatch also when compiling without udev support.

2016-04-01 22:36:40 +03:00
=================================
dev_manager: device_is_usable does not flush When scanning if device is being usable as PV, we call STATUS - but this status should not cause any flushing. Skip also open_count information as it's not needed.
2016-04-08 17:00:03 +03:00
Avoid using flushing dm status ioctl when checking for usable DM device.
activation: do not check for devs without LVM- Devices without "LVM-" uuid prefix have been generated by very old version of lvm2 2.00 and 2.01. Since version 2.02 all lvm2 devices are using prefix "LVM-". However checking for present of ancient non prefixed devices does take extra IOCTL per every call and for majority of todays user it will not find anything new. So use the assumption that users with kernel 3.X and newer are not really using such old versions of lvm2 (year <2005) and with their new kernel they are also using new version of lvm2 and skip checking for them. This change also makes trace logs more readable.
2016-04-07 22:37:26 +03:00
Check for devices without LVM- uuid prefix only with kernels < 3.X.
lvcreate: %FREE -> %PVS This is hotfix for RHBZ: https://bugzilla.redhat.com/1324537 However already the %FREE is not a good fit and we need something better. Meanwhile make -l%PVS work at least as good as %FREE for thin-pool. TODO: this needs rework - it should be allocator to do all the size decisions at one place.
2016-04-07 12:12:49 +03:00
Reuse %FREE size aproximation with lvcreate -l%PVS thin-pool.
lvmdump: Allow dir to exist already if it is empty
2016-04-07 00:36:42 +03:00
Allow the lvmdump directory to exist already provided it is empty.

Version 2.02.149 - 1st April 2016
=================================
thin: no thin-pool flush when reading metadata status Previous fix missed the fact the we do query for 'percent' with seg value either set or unset (API overload...) When 'seg' was unset, we still issue flush with status. Fix it by cheking segtype by target_type. As we check for segtype - we could also skip whole percentage if the 'segtype' is unknown by code directly. Reported-by: Ming-Hung Tsai <mingnus gmail com
2016-03-30 11:16:41 +03:00
Do not flush thin-pool when checking metadata fullness.
dev-cache: remove spurious error msg if no value found in /sys/dev/block/<major>:<minor>/dm/uuid during dev scan It's correct to have a DM device that has no DM UUID assigned so no need to issue error message in this case. Also, if the device doesn't have DM UUID, it's also clear it's not an LVM LV (...when looking for VGID/LVID while creating VGID/LVID indices in dev cache). For example: $ dmsetup create test --table "0 1 linear /dev/sda 0" And there's no PV in the system. Before this patch (spurious error message issued): $ pvs _get_sysfs_value: /sys/dev/block/253:2/dm/uuid: no value With this patch applied (no spurious error message): $ pvs
2016-03-30 12:11:37 +03:00
Remove spurious error about no value in /sys/dev/block/major:minor/dm/uuid.
dev-cache: also index VGIDs and LVIDs if using persistent .cache file If we're using persistent .cache file, we're reading this file instead of traversing the /dev content. Fix missing indexing by VGID and LVID here - hook this into persistent_filter_load where we populate device cache from persistent .cache file instead of scanning /dev. For example, inducing situation in which we warn about different device actually used than what LVM thinks should be used based on metadata: $ lsblk -s /dev/vg/lvol0 NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT vg-lvol0 253:4 0 124M 0 lvm `-loop1 7:1 0 128M 0 loop $ lvmconfig --type diff global { use_lvmetad=0 } devices { obtain_device_list_from_udev=0 } (obtain_device_list_from_udev=0 also means the persistent .cache file is used) Before this patch - pvs is fine as it does the dev scan, but lvs relies on persistent .cache file and it misses the VGID/LVID indices to check and warn about incorrect devices used: $ pvs Found duplicate PV B9gXTHkIdEIiMVwcOoT2LX3Ywh4YIHgR: using /dev/loop0 not /dev/loop1 Using duplicate PV /dev/loop0 without holders, ignoring /dev/loop1 WARNING: Device mismatch detected for vg/lvol0 which is accessing /dev/loop1 instead of /dev/loop0.

2016-03-30 11:39:30 +03:00
Fix device mismatch detection for LV if persistent .cache file is used.
dev-cache: handle situation where device is referenced in sysfs, but the node is not yet in dev dir It's possible that while a device is already referenced in sysfs, the node is not yet in /dev directory. This may happen in some rare cases right after LVs get created - we sync with udev (or alternatively we create /dev content ourselves) while VG lock is held. However, dev scan is done without VG lock so devices may already be in sysfs, but /dev may not be updated yet if we call LVM command right after LV creation (so the fact that fs_unlock is done within VG lock is not usable here much). This is not a problem with devtmpfs as there's at least kernel name for device in /dev as soon as the sysfs item exists, but we still support environments without devtmpfs or where different directory for dev nodes is used (e.g. our test suite). This patch covers these situations by tracking such devices in _cache.sysfs_only_names helper hash for the vgid/lvid check to work still. This also resolves commit 6129d2e64d14047169048775dc7081135c0fcc50 which was then reverted by commit 109b7e2095a7bc5603bf79db0224b8399463af7c due to performance issues it may have brought (...and it didn't resolve the problem fully anyway).
2016-03-30 11:29:35 +03:00
Fix holder device not being found in /dev while sysfs has it during dev scan.

Add pv_major and pv_minor report fields.
dev: detect mismatch between devices used and devices assumed for an LV It's possible for an LVM LV to use a device during activation which then differs from device which LVM assumes based on metadata later on. For example, such device mismatch can occur if LVM doesn't have complete view of devices during activation or if filters are misbehaving or they're incorrectly set during activation. This patch adds code that can detect this mismatch by creating VG UUID and LV UUID index while scanning devices for device cache. The VG UUID index maps VG UUID to a device list. Each device in the list has a device layered above as a holder which is an LVM LV device and for which we know the VG UUID (and similarly for LV UUID index). We can acquire VG and LV UUID by reading /sys/block/<dm_dev_name>/dm/uuid. So these indices represent the actual state of PV device use in the system by LVs and then we compare that to what LVM assumes based on metadata. For example: [0] fedora/~ # lsblk /dev/sdq /dev/sdr /dev/sds /dev/sdt NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdq 65:0 0 104M 0 disk |-vg-lvol0 253:2 0 200M 0 lvm `-mpath_dev1 253:3 0 104M 0 mpath sdr 65:16 0 104M 0 disk `-mpath_dev1 253:3 0 104M 0 mpath sds 65:32 0 104M 0 disk |-vg-lvol0 253:2 0 200M 0 lvm `-mpath_dev2 253:4 0 104M 0 mpath sdt 65:48 0 104M 0 disk `-mpath_dev2 253:4 0 104M 0 mpath In this case the vg-lvol0 is mapped onto sdq and sds becauset this is what was available and seen during activation. Then later on, sdr and sdt appeared and mpath devices were created out of sdq+sdr (mpath_dev1) and sds+sdt (mpath_dev2).

2016-03-11 03:21:53 +03:00
==================================
fsadm: if available, use /proc/self/mountinfo to detect mounted volume The /proc/self/mountinfo is not bound to device names like /proc/mounts and it uses major:minor pairs instead. This fixes a situation in which a volume is mounted and then renamed later on - that makes /proc/mounts unreliable when detecting mounted volumes. See also https://bugzilla.redhat.com/show_bug.cgi?id=1196910.
2016-03-18 15:42:06 +03:00
If available, use /proc/self/mountinfo to detect mounted volume in fsadm.
lvresize: fix stacked resize Commit b64703401da1f4bef60579a0b3766c087fcfe96a cause regression when handling stacked resize of pool metadata volume that would be a raid LV. Fix it by properly setting up size also for layer extension.
2016-03-16 01:13:28 +03:00
Fix resize of stacked raid thin data volume (2.02.141).
lvconvert: fix error path test lvremove_single toollib function returns ECMD_FAILED or ECMD_PROCESSED.
2016-03-15 01:19:22 +03:00
Fix test for lvremove failure in lvconvert --uncache (2.02.146).

Version 2.02.146 - 11th March 2016
==================================
man: updates Continuing with lvconvert style updates. Minimize usage of '\:' as zero-width break space, since html renderers do not handle this groff sign well (some of them seems to even render ':' there). But since we do not want see badly rendered man pages itself, prefer the 'man visual' appearence over html page generation (man2html should be actually fixed). Start to use 'user input option' with Capitals more consistently.
2016-03-03 22:27:09 +03:00
More man page cleanups in lvconvert.
makefiles: avoid using vpath for rules files Fixing vpath usage as it has been checking for existance of generated file also in the $(scrdir) e.g.: No need to remake target '10-dm.rules.in'; using VPATH name '...' If the $(srcdir) had been also $(builddir) and contained already generated rules file, it's been used instead generating new one. (See: http://make.mad-scientist.net/papers/how-not-to-use-vpath/)
2016-03-09 19:52:29 +03:00
Fix makefile vpath in /udev when generating udev rules files.
lvconvert: improve vg parameter parsing Commit abd9618dd8b77ca1974074ae76fa6a08f1a687d9 tried to improve parsing of vg name from logical path - but still missed couple corner cases. This patch further improves the logic and reuses validate_lvname_param() for parsing of lv_name. Also explicitly checks for LVM_VG_NAME in the right case. So now also properly parses cases like: 'lvconvert --repairt vg/' and will provide correct error message.
2016-03-08 12:13:38 +03:00
Another attempt to improve VG name parsing for lvconvert (2.02.144).
cache: check for cache fail during flush Just WARN if the cache can't be flushed because it's failed.
2016-03-10 19:56:43 +03:00
Use new cache status info and skip flushing for failed cache.
lvconvert: uncache handles missing PV Allow to process with --uncache when some PVs are missing in VG. So it's now possible to --uncache cached LV if the cache-pool has missing PV.
2016-03-08 12:47:27 +03:00
Support --uncache with missing PVs.
report: Tidy some field names, widths and headings. Specifying an output width of 0 now leads to a default minimum width taken from the width of the column heading. (Most fields should use this.) Components of field names are generally separated by underscores (which are optional at run-time). (Dropped 3 duplicate fields now covered by this rule.) Each field heading must be unique and generally doesn't have spaces between words (which get capitalised) unless they are already short and the fields are normally longer or clarity demands it.
2016-03-08 22:50:22 +03:00
Tidy report field names, headings and widths.
vgscan: add --notifydbus to send a notification This command option can be used to trigger a D-Bus notification independent of the usual notifications that are sent from other commands as an effect of changes to PV/VG/LV state. If lvm is not built with dbus notification support or if notify_dbus is disabled in the config, this command will exit with an error.
2016-03-07 19:50:45 +03:00
Add vgscan --notifydbus to send a dbus notification.
dbus: add notification from commands When a command modifies a PV or VG, or changes the activation state of an LV, it will send a dbus notification when the command is finished. This can be enabled/disabled with a config setting.
2016-02-22 18:42:03 +03:00
Add dbus notification from commands after a PV/VG/LV changes state.

=================================
WHATS_NEW: historical LVs
2016-03-04 14:08:02 +03:00
Make it possible to use lvremove and lvrename on historical LVs.
For historical LVs, report 'none' for lv_layout and 'history' for lv_role.
Add full_{ancestors,descendants} fields to report LV ancestry with history.
Report (h)istorical state within 5th bit (State) of the lv_attr field.
Add lv_historical reporting field to report if LV is historical or not.
Add lv_time_removed reporting field to display removal time for hist. LVs.
Report lv_name, lv_uuid, vg_name, lv_time for historical LVs.
Add --nohistory switch to lvremove to disable history recording on demand.
Add -H|--history switch to lvs and lvdisplay to include historical LVs.
Create historical LVs out of removed thin snapshot LVs and record in history.
Add metadata/lvs_history_retention_time for automatic removal of hist. LVs.
Add metadata/record_lvs_history config for switching LV history recording.
Add support and infrastructure for tracking historical LVs.
man: lvconvert updates Improving style (following lvcreate way). Sorting options alphabetically.
2016-03-03 01:51:16 +03:00
Improve lvconvert man page.
cache: add kernel_cache_policy option Pair kernel_cache_settings with kernel_cache_policy. There is very small chance in error case that the value in table might be differnet from the value stored in metadata so make it 'checkable'.
2016-03-02 13:12:46 +03:00
Add kernel_cache_policy lvs field.
WHATS_NEW: [unknown] replaces 'unknown device'
2016-03-01 20:16:35 +03:00
Display [unknown] instead of 'unknown device' in pvs output.
coverity: missing error path
2016-03-01 13:40:53 +03:00
Fix error path when pvcreate allocation fails (2.02.144).
update WHATS_NEW including changes not recorded for the previous release.
2016-02-29 22:50:02 +03:00

=====================================
update WHATS_NEW including changes not recorded for the previous release.
2016-02-29 22:50:02 +03:00
Use new PV processing code in pvcreate/vgcreate/vgextend/pvremove.
Add new PV processing code that prompts user without locks held.
Prevent lvmlockd blocking with new flag requiring sanlock 3.3.0.
report: Shift (u)sed pv_attr under (a)llocatable. Showing 'u' in the pv_attr reporting field is mostly unnecessary because most PVs are allocatable, and being allocatable implies it is (u)sed, and this is already obvious from other fields in the default 'pvs' output like the VG name. So move the new (u)sed pv_attr from character position 4 to 1, and only show it in those rare cases when the PV is not (a)llocatable or the relevant metadata is missing. (Scripts should not be using pv_attr, but rather pv_allocatable, pv_exported, pv_missing, pv_in_use etc.)
2016-02-26 18:46:37 +03:00
Only show (u)sed pv_attr char when PV is not (a)llocatable. (2.02.143)
makefiles: add more dirs for lcov output New daemons were missing in generated lcov output.
2016-02-26 12:14:39 +03:00
Update makefile to generate lcov output also for lvmpolld and lvmlockd.
dbus: fix the systemd service providing the DBus service Correct name is lvm2-lvmdbusd.service not lvmdbusd.service. This makes the bus-activation (auto-activation) work. Signed-off-by: Vratislav Podzimek <vpodzime@redhat.com>
2016-02-25 18:34:41 +03:00
Fix SystemdService lvm2-lvmdbusd.service name.
lvconvert: fix vg parameter Since we want to read env LVM_VG_NAME vg names, we cannot just check LV names which do contain '/'. So before the patch commands like: > lvconvert --repair vg Before: Please provide a valid volume group name After: Path required for Logical Volume "vg". Please provide a valid volume group name > LVM_VG_NAME=vg lvconvert --repair vg Before: Please provide a valid volume group name After: Can't find LV vg in VG vg
2016-02-25 22:40:28 +03:00
Improve support for env LVM_VG_NAME for reference VG name in lvconvert.
pre-release
2016-02-27 00:03:30 +03:00
Fix regression when lvresize accepted zero sizes. (2.02.141)
pvremove: add warn when removing PV in use Reshuffle messages during pvremove. Always print WARNING: when PV is in use so using options --force --force doesn't make this important user notification go away. Simplify variable 'used' usage (so older gcc doesn't warn about the use of unitilizied variable). Add some '.' into messages.
2016-02-23 16:10:45 +03:00
Always warn user about PV in use even when pvremove uses --force --force.
pre-release
2016-02-27 00:03:30 +03:00

=====================================
thin: fix update_pool_lv error path When update fails in suspend() (sending of messages fails because metadata space is full) call resume(), so the locking sequence works properly for clustering. Also failing deactivation should unlock memory.
2016-02-19 13:18:41 +03:00
Fix error path when sending thin-pool message fails in update_pool_lv().
thin: report needs_check and fail state Fix reporting of Fail thin-pool target status as attr[8] letter 'F'. Report 'needs_check' status from thin-pool target via attr field [4] (letter 'c'/'C'), and also via CheckNeeded field. TODO: think about better name here? TODO: lots of prop_not_implemented_set
2016-02-18 15:19:25 +03:00
Support reporting CheckNeeded and Fail state for thin-pool and thin LV.
thin: report PERCENT_INVALID for failed pool When thin-pool is in failed/error state, we can't read percentage so report invalid value.
2016-02-18 15:18:18 +03:00
For failing thin-pool and thin volume correctly report percentage as INVALID.
report: report -1, not 'unkown' for lv_{snapshot_invalid,merge_failed} with --binary State: $ lvs -o lv_name,lv_active_locally,lv_snapshot_invalid,lv_merge_failed vg/lvol0 LV ActLocal SnapInvalid MergeFailed lvol0 active locally unknown unknown Now with using --binary switch. Before this patch (lv_snapshot_invalid and lv_merge_failed not switched into numeric value where -1 represents 'unknown' value) $ lvs -o lv_name,lv_active_locally,lv_snapshot_invalid,lv_merge_failed vg/lvol0 --binary LV ActLocal SnapInvalid MergeFailed lvol0 1 unknown unknown With this patch applied: $ lvs -o lv_name,lv_active_locally,lv_snapshot_invalid,lv_merge_failed vg/lvol0 --binary LV ActLocal SnapInvalid MergeFailed lvol0 1 -1 -1
2016-02-18 14:10:00 +03:00
Report -1, not 'unkown' for lv_{snapshot_invalid,merge_failed} with --binary.
lvmdbus: Add new daemon.
2016-02-18 02:53:35 +03:00
Add configure --enable-dbus-service for an LVM D-Bus service.
WHATS_NEW
2016-02-18 03:01:02 +03:00
Replace configure --enable-python_bindings with python2 and python3 versions.
toollib: skip PV if system ID is used and PV marked as used but metadata missing If we know that a PV belongs to some VG and we're missing metadata (because we have only those PV(s) from VG present in the system that don't have metadata areas), we should skip such PV when processing under system ID. This is because we know that the PV belongs to some VG, but we really can't decide whether it matches system ID unless the VG metadata is present again.
2016-02-15 17:11:54 +03:00
If PV belongs to some VG and metadata missing, skip it if system ID is used.
WHATS_NEW: PV_EXT_USED flag and related
2016-02-15 15:07:35 +03:00
Automatically change PV header extension to latest version if writing PV/VG.
Identify used PVs in pv_attr field by new 'u' character.
Add pv_in_use reporting field to report if PV is used or not.
Add pv_ext_vsn reporting field to report PV header extension version.
Add protective flag marking PVs as used even if no metadata available.

=====================================
pvmove: fix possible memory pool corruption This is a hotfix for a bug introduced in 6d7dc87cb356162f912b13c8a0cd198037c0226b. The bug description: First we allocate memory for processing handle (at an address 1) then we allocate some memory on the same pool for later use in pvmove_poll function inside the process_each_pv function (at an address 2). After we jump out of process_each_pv we called destroy_processing_handle. As a result of destroying the handle memory pool could deallocate all memory at address 1 or higher. The pvmove_poll function tried to copy a memory allocated at address 2 that could be returned to the system. If it was so it led to segfault. We need to rethink proper fix but in the same time cmd->mem pool is recreated per each lvm command so this should not cause problems even when we run multiple commands in lvm shell. A valgrind snapshot of the corruption: Invalid read of size 1 at 0x4C29F92: strlen (mc_replace_strmem.c:403) by 0x5495F2E: dm_pool_strdup (pool.c:51) by 0x1592A7: _create_id (pvmove.c:774) by 0x159409: pvmove_poll (pvmove.c:796) by 0x1599E3: pvmove (pvmove.c:931) by 0x15105B: lvm_run_command (lvmcmdline.c:1655) by 0x1523C3: lvm2_main (lvmcmdline.c:2121) by 0x1754F3: main (lvm.c:22) Address 0xf15df8a is 138 bytes inside a block of size 8,192 free'd at 0x4C28430: free (vg_replace_malloc.c:446) by 0x5494E73: dm_free_wrapper (dbg_malloc.c:357) by 0x5495DE2: _free_chunk (pool-fast.c:318) by 0x549561C: dm_pool_free (pool-fast.c:151) by 0x164451: destroy_processing_handle (toollib.c:1837) by 0x1598C1: pvmove (pvmove.c:903) by 0x15105B: lvm_run_command (lvmcmdline.c:1655) by 0x1523C3: lvm2_main (lvmcmdline.c:2121) by 0x1754F3: main (lvm.c:22)
2016-02-12 13:34:26 +03:00
Fix memory pool corruption in pvmove (2.02.141).
lvconvert: enable spare creation during conversion Let user control pool metadata spare creation after repair as the VG might not have enough free space.
2016-01-27 14:11:03 +03:00
Support control of spare metadata creation when repairing thin-pool.
config: fix verbose type to int 'verbose' was marked as a boolean option while it takes integer args - so it has limited usage to 0 or 1, but we supported 0-4 at least. Fix it by switching to corrent int type. (Hopefully noone was trying to use this variable as true/yes/false/no way - as the would be unsupported/undocumented).
2016-01-27 14:11:03 +03:00
Fix config type of 'log/verbose' from bool to int (2.02.99).
pre-release
2016-02-15 13:35:16 +03:00
Fix inverted data LV thinp watermark calc for dmeventd response (2.02.133).
conf: use use_blkid_wiping=0 if not defined in lvm.conf and support not compiled in Normally, we generate and provide lvm.conf file where use_blkid_wiping is set based on whether support for this is compiled in or not. This was generated properly based on configure. However, if lvm.conf is not used at all (someone deletes it) or the value in lvm.conf is commented out (user edited it), we still need to use proper default value that is based on DEFAULT_USE_BLKID_WIPING taken from configure script - we used hardcoded value of "1" in this case by mistake.
2016-02-10 16:53:10 +03:00
Use use_blkid_wiping=0 if not defined in lvm.conf and support not compiled in.
filter: do not check for suspended devs in filter-usable in lvmetad mode We already do check for suspended devs within udev rules where the pvscan is to update lvmetad. So the check for suspended devs in "pre-lvmetad" chain is not useful here - remove it - it may be a source of hardly to detect races anyway (if udev rule detects the device is not suspended and then the pvscan instance sees the dev as suspended, we may end up not reacting to the event properly).
2016-02-03 16:40:52 +03:00
Do not check for suspended devices if scanning for lvmetad update.
pre-release
2016-02-15 13:35:16 +03:00

====================================
conf: add metadata/check_pv_device_sizes
2016-01-22 15:20:21 +03:00
Add metadata/check_pv_device_sizes switch to lvm.conf for device size checks.
metadata: check PV dev size is not less than PV size
2016-01-22 13:37:09 +03:00
Warn if device size is less than corresponding PV size in metadata.
device: also cache device size Add "size" and "size_seqno" to struct device to cache device's size and also to control its lifetime - the cached value is valid as long as the global _dev_size_seqno is equal to the device's size_seqno, otherwise we need to get the size again and cache the new value. This patch also adds new dev_size_seqno_inc() fn for the appropriate parts of the code to increment current global value of _dev_size_seqno and hence to cause all currently cached values for device sizes to be invalidated. The device size is now cached because we're planning to reuse this information for further checks and we want to avoid checking it more than necessary to save resources.
2016-01-15 18:41:27 +03:00
Cache device sizes internally.
toollib: restore command break support Fix regression caused by c9f021de0b4d2c873ef5b97d17c602d0380359fd. This commit actually transfered real-action (e.g. device removal) into the next loop which has however missed to check for break. So add check for break also there.
2016-01-21 15:19:27 +03:00
Restore support for command breaking in process_each_lv_in_vg() (2.02.118).
toollib: use cmd mempool for list When creating a list in 'context of command' - use proper mempool. vg->vgmem is mempool related to VG metadata - and can be eventually locked read-only when VG struct is shared.
2016-01-21 15:18:11 +03:00
Use correct mempool when process_each_lv_in_vg() (2.02.118).
man: show hidden pieces W: manual-page-warning /usr/share/man/man8/lvm.8.gz 491: warning: macro `_cdata',' not defined rpmlint actually notices we had few hidden word in man page. the line cannot start with apostrophe as it has then a different meaning.
2016-01-21 13:31:18 +03:00
Fix lvm.8 man to show again prohibited suffixes.
configure: fix configure to set proper use_blkid_wiping if autodetected as disabled If not using explicit --enable-blkid-wiping/--disable-blkid-wiping configure option, the configure script tries to enable/disable blkid wiping feature automatically based on blkid library version found. The script incorrectly set default value for lvm.conf's allocation/use_blkid_wiping" setting to "1" (enabled) if proper blkid library version was not found or the version found was less than the minimum required. It should be set to "0" in this case.
2016-01-21 11:56:07 +03:00
Fix configure to set proper use_blkid_wiping if autodetected as disabled.
clvmd: Initialise udev. Since commit 2fc126b00d83991c6a2f3ed9aa61457294a4c45e, the library code requires udev to be initialised for device scanning and clvmd can fail to find VGs if devices/external_device_info_source is set to "udev".
2016-01-20 03:58:09 +03:00
Initialise udev in clvmd for use in device scanning. (2.02.116)
report: add seg_le_ranges report field
2016-01-19 15:51:11 +03:00
Add seg_le_ranges report field for common format when displaying seg devices.
report: make devices, metadata_devices, seg_pe_ranges and seg_metadata_le_ranges fields consistent There are two basic groups of fields for LV segment device reporting: - related to LV segment's devices: devices and seg_pe_ranges - related to LV segment's metadata devices: metadata_devices and seg_metadata_le_ranges The devices and metadata_devices report devices in this format: "device_name(extent_start)" The seg_pe_ranges and seg_metadata_le_ranges report devices in this format: "device_name:extent_start-extent_end" This patch reverts partly what commit 7f74a995029caa41ee3cf9aec0bd024a34bfd89a (v 2.02.140) introduced in this area - it added [] for hidden devices to mark them for all four fields mentioned above. We won't be marking hidden devices in devices and metadata_devices fields. The seg_metadata_le_ranges field will have hidden devices marked - it's new enough that we don't need to care about compatibility much yet. The seg_pe_ranges is old enough that we shouldn't be changing this one - so we're reverting to not marking hidden devices here. Instead, there's going to be a new field "seg_le_ranges" which is going to replace the seg_pe_ranges and it will mark hidden devices - this is going to be introduced in a patch later. So in the end we'll end up with: (LV segment's devices) devices field with "device_name(extent_start)" format, not marking hidden devices seg_pe_ranges field with "device_name:extent_start-extent_end" format, not marking hidden devices (deprecated, new seg_le_ranges should be used instead for standardized format) seg_le_ranges field with "device_name:extent_start-extent_end" format, marking hidden devices (LV segment's metadata devices) metadata_devices field with "device_name:extent_start-extent_end" format, not marking hidden devices seg_metadata_le_ranges field with "device_name:extent_start-extent_end" format, marking hidden devices Also, both seg_le_ranges and seg_metadata_le_ranges will honour the report/list_item_separator setting which can be used to configure the delimiter used for list items. So, to sum it up, we will recommend using the new seg_le_ranges and seg_metadata_le_ranges fields because they display devices with standard extent range format, they can mark hidden devices and they honour the report/list_item_separator setting. We'll be keeping devices,seg_pe_ranges and metadata_devices fields for compatibility.
2016-01-19 14:26:01 +03:00
Honour report/list_item_separator for seg_metadata_le_ranges report field.
clvmd: Initialise udev. Since commit 2fc126b00d83991c6a2f3ed9aa61457294a4c45e, the library code requires udev to be initialised for device scanning and clvmd can fail to find VGs if devices/external_device_info_source is set to "udev".
2016-01-20 03:58:09 +03:00
Don't mark hidden devs in -o devices,metadata_devices,seg_pe_ranges.(2.02.140)
report: Fix seg_pe_ranges LV sizes. When reporting on LVs, take the end of the range from the size of the underlying (hidden) LV rather than the logical size of the current segment (that PVs use).
2016-01-19 01:04:43 +03:00
Change LV sizes in seg_pe_ranges report field to match underlying devices.
report: add kernel_cache_settings field Existing cache_settings field displays the settings which are saved in metadata. Add new kernel_cache_settings fields to display the settings which are currently used by kernel, including fields for which default values are used. This way users have complete view of the set of cache settings supported (and which they can set) and their values which are used at the moment by kernel. For example: $ lvs -o name,cache_policy,cache_settings,kernel_cache_settings vg LV Cache Policy Cache Settings KCache Settings cached1 mq migration_threshold=1024,write_promote_adjustment=2 migration_threshold=1024,random_threshold=4,sequential_threshold=512,discard_promote_adjustment=1,read_promote_adjustment=4,write_promote_adjustment=2 cached2 smq migration_threshold=1024 migration_threshold=1024 cached3 smq migration_threshold=2048
2016-01-18 16:32:17 +03:00
Add kernel_cache_settings report field for cache LV settings used in kernel.

Version 2.02.140 - 16th January 2016
====================================
lvm2app: fix lvm2app to return either 0 or 1 for lvm_vg_is_{clustered,exported} Fix lvm2app to return either 0 or 1 for lvm_vg_is_{clustered,exported}, including internal functions pvseg_is_allocated and vg_is_resizeable which are not yet exposed in lvm2app but make them consistent with the rest.
2016-01-15 16:39:43 +03:00
Fix lvm2app to return either 0 or 1 for lvm_vg_is_{clustered,exported}.
report: add kernel_discards report field to display thin pool discard used in kernel Thin pool discard mode set in metadata can be different from the one actually used if any device underneath does not support that mode. Add kernel_discard report field to make it possible to see this difference.
2016-01-14 18:54:12 +03:00
Add kernel_discards report field to display thin pool discard used in kernel.
segtype: check for activation Before setting static variable with check passed state, detect if we are allowed to talk to driver.
2015-12-17 14:23:33 +03:00
Correct checking of target presence when driver access is disabled.
lvresize: check for poolmetadatasize arg earlier Since we check for poolmetadatasize, we need to detect it before actual test.
2015-12-16 13:23:45 +03:00
Eval poolmetadatasize arg earlier in lvresize.
vgcfgrestore: Retain allocatable PV attribute. pvchange -xn was getting lost. All PVs were set to allocatable again after restore. Moved setting ALLOCATABLE_PV outside pv_setup().
2016-01-14 03:46:45 +03:00
Fix vgcfgrestore to respect allocatable attribute of PVs.
cleanup: rename 'invisible devices' to 'hidden devices'
2016-01-13 17:21:05 +03:00
Add report/mark_hidden_devices to lvm.conf.
Use brackets consistently in report fields to mark hidden devices.
pvscan: restore polling in autoactivation handler This commit fixes regression in auto-activation code introduced in commit: c26d81d6e6939906729d91fae83cd8bbdd743bb7. - resolves rhbz1295562
2016-01-07 17:17:08 +03:00
Restore background polling processing during auto-activation (2.02.119).
report: fix invalid memory read when reporting cache LV policy name Fix regression caused by commit c2d4330f27277717bc3b684b702189079b257b77 which removed the dm_pool_strdup for the cache policy name in _cache_policy_disp report function. This regression was hit with buffered reporting only (which is used by default). The reason is that for buffered reporting, we're iterating over LVs in VG (process_each_lv) while gathering all the information that is needed for the report. In this case, the LV's cache policy name has not been duped, but only the pointer to the original VG buffer was stored. When the LV iteration finished, the VG buffer was freed and any report to output called later (dm_report_output call) accessed already freed VG data. This didn't appear if unbuffered reporting was used (--unbuffered) because in this case, the data were reported to output as soon as they were processed, hence it was reported to output before the VG data was freed.
2016-01-11 14:51:08 +03:00
Fix invalid memory read when reporting cache LV policy_name (2.02.126).

lvmdump: also add lvm2-activation{-early,-net}.service systemd status for lvmdump -s The lvm2-activation{-early,-net}.service systemd unit statuses were missing in dump gathered by lvmdump -s. These are quite important when debugging scenarios with systemd environment and where lvmetad is not used.

vgextend: reinstantiate archiving Since commit f5d06efbab4c7c77298b18b95c23111575a8db1a we lost archiving. Restore it now with process_each_vg.
2015-12-03 20:15:02 +03:00
Restore archiving before changing metadata in vgextend (2.02.117).
cleanup: drop log_suppress(2) usage No longer need to use log_suppress(2) instance so dropped.
2015-12-03 19:51:43 +03:00
Dropped internal usage of log_suppress(2).
log: use full buffer size for printf Pass full buffer size to printf() function - no reason to make buffer 1 char smaller. Also rename locn buffer to message buffer directly since it's not used for anything else. TODO: we may use same buffer also for 'buf[]' since there is no collision - so may safe 1K on stack usage.
2015-12-03 17:28:01 +03:00
Cleaned logging code for buffer size usage.
uuid: add id_read_format_try Provide id_read_format() functionality without log_error when ID is not valid one - it will just return 0. Does not need to use log_suppress() then.
2015-12-03 17:25:09 +03:00
Added internal id_read_format_try() function to check and read valid UUID.
pre-release
2015-12-05 18:33:19 +03:00
Change lvcreate, lvrename, lvresize to use process_each_vg.
Change process_each_vg to handle single VG as separate arg.
Issue error if ambiguous VG name is supplied in most commands.
Make process_each fns always work through full list of known VG names.
cleanup: use dm_get_status_mirror Use libdm function to parse mirror status report.
2015-11-30 23:17:25 +03:00
Use dm_get_status_mirror() instead of individual parsers.
lib: pass mem pool to check_transient_status check_transient_status() may need to allocate some memory, so pass in already existing mem pool.
2015-11-30 23:24:31 +03:00
Add mem pool arg for check_transient_status() target function.
lvconvert: Improve message for raid without -m.
2015-12-01 01:36:05 +03:00
Avoid misleading error with -m is omitted with lvconvert to raid types.

post-release
2015-11-23 06:40:34 +03:00
=====================================
lvmconfig: add --sinceversion for --type new Just for convenience to display all new configuration settings introduced since given version (before, there was only --atversion to display settings introduced in concrete version). For example: $ lvmconfig --type new --sinceversion 2.2.120 allocation { # cache_mode="writethrough" # cache_settings { # } } global { use_lvmlockd=0 # lvmlockd_lock_retries=3 # sanlock_lv_extend=256 use_lvmpolld=1 } activation { } # report { # compact_output_cols="" # time_format="%Y-%m-%d %T %z" # } local { # host_id=0 }
2015-11-25 16:09:20 +03:00
Add new --sinceversion option for lvmconfig --type new.
thin: work with active thin-pool When 'lvextend -L+XX vg/thinpool' do not leave inactive table loaded for 'wrapping' LV on top of resized thin-pool (ATM we use linear LV for this with same size as thin-pool).
2015-11-23 21:53:43 +03:00
Fix inactive table loaded for wrapping thin-pool when resizing it.
memlock: add more libs on ignore list Udev recently start to 'link-in' major amount of useless libs. (Seem to be faulty 'systemd' link-in all issue) Anyway - avoid locking those libs in RAM.
2015-11-22 02:26:06 +03:00
Extend the list of ignored libraries when locking memory.

Version 2.02.135 - 23rd November 2015
=====================================
Add a model file for Coverity.
cache: lvconvert repairs only thin pools Avoid internal error message where thin pool repair code tries to fix cache pool - was catched later in code stack, so rather catch this early and make the repair function exlusive to thin pools. So far we have no code for repairing cache pools (other then the automatic during activation/deactivation).
2015-11-19 15:32:03 +03:00
Show correct error message for unsupported yet cache pool repair.
cache: enable raid conversion for _cdata and _cmeta Since thin-pool supports convertion of data and metadata LV, enable the same for cache data and metadata LV.
2015-11-19 15:30:55 +03:00
Allow lvconvert cache pools' data and metadata LV to raid.
cache: handle older metadata format When reading older lvm2 metadata for cache-pool - we now handle more extended syntax - basically we want to enter most setting when actually creating cached LV. For this new validation code has been added. However older metadata without new settings set is now found as invalid. Fix it by adding default settings for cache policy mq and cache mode writethrough.
2015-11-15 22:03:08 +03:00
Fix reading of old metadata with missing cache policy or mode settings.
dev-ext: issue error if external_device_info_source=udev and udev db record incomplete Udev db records are marked as not initialized (incomplete) on timeout. Issue an error message whenever LVM finds such records so users are aware that something's going wrong with udev db. This is important in case we use devices/external_device_info_source="udev" where udev database records are used to do various filtering decisions. For example: udev log of timed out worker: Nov 11 13:02:25 raw.virt systemd-udevd[607]: seq 1997 '/devices/virtual/block/dm-2' is taking a long time Nov 11 13:04:25 raw.virt systemd-udevd[607]: seq 1997 '/devices/virtual/block/dm-2' killed Nov 11 13:04:25 raw.virt systemd-udevd[607]: worker [11221] terminated by signal 9 (Killed) Nov 11 13:04:25 raw.virt systemd-udevd[607]: worker [11221] failed while handling '/devices/virtual/block/dm-2' ... LVM also issues error message visibly if incomplete udev db record is found, devices/external_device_info_source="udev" is set: $ pvs Udev database has incomplete information about device /dev/dm-2. Failed to get external handle for device /dev/dm-2 [udev]. ...
2015-11-11 15:13:54 +03:00
Issue error if external_device_info_source=udev and udev db record incomplete.
pre-release
2015-11-23 06:33:43 +03:00
Update lvmetad duplicate VG name handling to use hash function extensions.
Detect invalid vgrenames by vgid where the name is unchanged.
libdaemon: fix passing 32bit values for %d Since %d is now prohibited for its great confusion, replace it with FMTd64 and correctly converted int64_t parameter.
2015-11-09 17:15:37 +03:00
Fix passing of 32bit values through daemons (mostly lvmlockd).
alloc: use own mem pool for alloc_handle Keep alloc_handle's data in a single mempool and do not spread them into vgmem pool.
2015-11-04 16:54:07 +03:00
Use local memory pool for whole alloc_handle manipulation.
devmanager: validate target params Coverity: ensure we do not read through NULL pointers for target_type and params.
2015-11-09 11:27:18 +03:00
Add missing pointer validation after dm_get_next_target().
lv_manip: do not deref NULL for debug message Coverity: when 'pv2' would be passed as NULL, do not try to deref it in debug message.
2015-11-09 11:28:59 +03:00
Do not deref NULL pointer in debug message for _match_pv_tags().
dev-type: fix TOCTOU order Doing 'stat' checking first and later opening is racy. And since we do not really care about any 'status' info here and we read 'sysfs' here - just drop whole 'stat()' call and directly handle error from failing 'fopen()'.
2015-11-08 19:15:24 +03:00
Drop unneeded stat() call when checking for sysfs file.
thin: fix error path mem leak Coverity: when parsing of thin-pool status would have failed, it could have leaked memory pool and dmt struct.
2015-11-08 19:04:03 +03:00
Fix memory leak on error path of failing thin-pool percentage check.
lvmetad: check for allocation fail Coverity: missing check for root != NULL as this pointer is later dereferenced in add_last_node().
2015-11-08 21:38:19 +03:00
Add missing test for failing node allocation in lvmetad.
configure: report whether to build lvmlockd Report configured status for build with lvmlockd.
2015-11-02 22:04:50 +03:00
Correct configure messages when enabling/disabling lvmlockd.

2015-11-09 04:45:22 +03:00
Refactor some lvmetad code and adjust some duplicate PV messages.
No longer repair/wipe VG/PVs if inaccessible because foreign or shared.
mirror: Fix log size calc when more than 1 extent. Currently the code creates the log separately after allocating space for the data and as no data allocation is needed this second time, total_extents ends up holding zero so use new_extents directly instead.
2015-11-06 02:40:47 +03:00
Pass correct data size to mirror log calc so log can be bigger than 1 extent.

====================================
WHATS_NEW: reporting commands and -o-/-o+ extension
2015-10-30 17:50:35 +03:00
Support repeated -o|--options for reporting commands.
Support -o- and -o# for reporting commands to remove and compact fields.
New entries for pvs related fixes.
2015-10-30 17:05:21 +03:00
Fix missing PVs from pvs output if vgremove is run concurrently.
Remove unwanted error message when running pvs/vgs/lvs and vgremove at once.
WHATS_NEW: recent commits
2015-10-29 18:50:09 +03:00
Check newly created VG's metadata do not overlap in metadata ring buffer.
Check metadata area size is at least the minimum size defined for the format.
thin: enable usage of kernel low_water_mark Now with correctly functioning dmeventd enable usage of low_water_mark for faster reaction on pool's threshold. When user select e.g. 80% as a threshold value, dmeventd doesn't need to wait 10 seconds till monitoring timer expires, but nearly instantly resizes thin-pool to fit bellow threshold.
2015-10-29 13:58:06 +03:00
Thin pool targets uses low_water_mark from profile.
cleanup: snapshots of snapshots message No plans to support thick snapshost of snapshots.
2015-10-22 14:32:52 +03:00
Dropping 'yet' from error of unsupported thick snapshot of snapshots.
pvcreate: don't support unpartitioned DASD devices with CDL formatted The former patch(dab3ebce4c7) is a little bit strict. For example, it is OK to create PV on unpartitioned DASD devices with LDL formatted. So after lvm version containing the patch, LVs created on those devices could not be found. Signed-off-by: Lidong Zhong <lzhong@suse.com>
2015-10-12 10:09:11 +03:00
Do not support unpartitioned DASD devices with CDL formatted with pvcreate.
thin: limit no-flush using only for thin-pool For this release keep usage of 'noflush' only for thin-volume/pool. For rest of keep - keep usage of 'noflush' flag purely for non-resized mirrors.
2015-10-26 23:46:54 +03:00
For thins use flush for suspend only when volume size is reduced.
dev_manager: enabled no_flush for suspend While the activation code tries to evaluate which target really needs flush with suspend and which may go without flush, it has stayed effectively disabled by original commit: 33f732c5e9493cda4b161a18b3d53885d207e3b8 since here it only allows to pass non-pvmoving 'mirrors'. So remove check for mirror LV type and only disable no_flush for 'pvmove'.. TODO: Looking into history - it also seemed like raid target would have always required flushing but it's been later removed without clean explanation. If some more targets really do need 'no_flush' it should been handle at their 'level' - since we now stack multiple targets over itself.
2015-10-25 22:37:39 +03:00
Enable code which detects the need of flush during suspend.
lv_manip: ensure it will fit bellow threshold Use single code to evaluate if the percentage value has crossed threshold. Recalculate amount value to always fit bellow threshold so there are not need any extra reiterations to reach this state in case policy amount is too small.
2015-10-25 21:19:39 +03:00
Ensure --use-policy will resize volume to fit below threshold.
thin: fix percentage compare Since plugin's percentage compare has been fixed, it's now revealed wrong compare here. The logic for threshold is - to allow to go as high as given value e.g. 80% - so if pool is exactlu 80% full it's still allowed to use it (dmeventd will not resize it).
2015-10-25 21:13:53 +03:00
Correct percentage evaluation when checking thin-pool over threshold.
lvmcache: update cached info properly when moving from VG to orphan while lvmetad is used When lvmetad is used and lvmcache update function (lvmcache_update_vgname_and_id) was called to update existing lvmcache records, a condition was met which made to retun from the update function immediately, effectively making it NOOP. It seems there's no reason for such condition and lvmcache should be update appropriately even when lvmetad used as lvmcache may be reused, most notably in lvm shell. It's possible this is a remnant of the lvmetad development code which didn't get removed for some reason and the bug didn't get spotted because lvm shell is not used often (the condition dates back to 2012 or so). Example, lvmetad and lvm shell used: lvm> pvs PV VG Fmt Attr PSize PFree /dev/sda vg lvm2 a-- 124.00m 124.00m Before this patch: ================== lvm> vgremove vg Volume group "vg" successfully removed lvm> pvs With this patch applied: ======================== lvm> vgremove vg Volume group "vg" successfully removed lvm> pvs PV VG Fmt Attr PSize PFree /dev/sda lvm2 --- 128.00m 128.00m
2015-10-23 16:05:48 +03:00
Fix lvmcache to move PV from VG to orphans if VG is removed and lvmetad used.
pvremove: make sure even invalid info is removed from lvmcache on pvremove The lvmcache info might be resued, most notably in lvm shell. We need to be sure that even lvmcache_info marked as invalid is removed from the lvmcache so it does not confuse any subsequent code/commands executed later on. Problematic example with the lvm shell: lvm> pvs PV VG Fmt Attr PSize PFree /dev/sda lvm2 --- 128.00m 128.00m Before this patch (/dev/sda still displayed in a way): ====================================================== lvm> pvremove /dev/sda Labels on physical volume "/dev/sda" successfully wiped (without lvmetad) lvm> pvs No physical volume label read from /dev/sda (with lvmetad) lvm> pvs PV VG Fmt Attr PSize PFree /dev/sda lvm2 --- 128.00m 128.00m With this patch applied: ======================== lvm> pvremove /dev/sda Labels on physical volume "/dev/sda" successfully wiped (without lvmetad) lvm> pvs (with lvmetad) lvm> pvs
2015-10-23 15:11:16 +03:00
Fix lvmcache to not cache even invalid info about PV which got removed.
memlock: report memlock daemon counter Add internal memlock_count_daemon(). Function can be used to recognize it's being executed from daemon restricted execution inside /lib code.
2015-10-22 11:43:58 +03:00
Support checking of memlock daemon counter.
man: document possible lvmetad -l values In the man page and the lvmetad help output.
2015-10-21 21:36:57 +03:00
Allow all log levels to be used with the lvmetad -l option.
lvmetad: add optional timeout option
2015-10-20 14:24:50 +03:00
Add optional shutdown when idle support for lvmetad.
polldaemon: fix missing mirror in-sync info with lvmpolld CONVERTING status flag is a tricky one. It's not set when converting a non-mirror LV type to the mirror type, i.e.: linear -> two leg mirror. Also the conversion itself is instant and doesn't require to be polled. When mirror reaches sync state there's no final update on VG metadata for lvmpolld to be made thereby report_progress in fact doesn't report percentage of mirror being converted but percentage of mirror being in sync. Perhaps we should reword the lvconvert output here. On the other hand CONVERTING is set while we upconvert the mirror from i.e. two leg mirror to four leg mirror. In such case the operation is required to be polled so that lvmpolld can cleanup temporary conversion log when the conversion is over. Ignore CONVERTING lv_type for the moment and match LVs only by uuids during 'mirror conversion'/'waiting for a sync to finish'.
2015-10-19 17:56:45 +03:00
Fix missing in-sync progress info while lvconvert used with lvmpolld.
config: add report/compact_output_cols to control which columns to compact in report output The new report/compact_output_cols setting has exactly the same effect as report/compact_output setting. The difference is that with the new setting it's possible to define which cols should be compacted exactly in contrast to all cols in case of report/compact_output. In case both compact_output and compact_output_cols is enabled/set, the compact_output prevails. For example: $ lvmconfig --type full report/compact_output report/compact_output_cols compact_output=0 compact_output_cols="" $ lvs vg LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert lvol0 vg -wi-a----- 4.00m --- $ lvmconfig --type full report/compact_output report/compact_output_cols compact_output=0 compact_output_cols="data_percent,metadata_percent,pool_lv,move_pv,origin" $ lvs vg LV VG Attr LSize Log Cpy%Sync Convert lvol0 vg -wi-a----- 4.00m --- $ lvmconfig --type full report/compact_output report/compact_output_cols compact_output=1 compact_output_cols="data_percent,metadata_percent,pool_lv,move_pv,origin" $ lvs vg LV VG Attr LSize lvol0 vg -wi-a----- 4.00m
2015-10-16 17:25:51 +03:00
Add report/compact_output_cols to lvm.conf to define report cols to compact.
toolcontext: do not change already set dm_log If the dm_log is already set to non-default logger, avoid to change it.
2015-10-09 22:38:50 +03:00
Do not change logging in lvm2 library when it's already set.
thin: check for overflown pool earlier Check for pool early before we actually start to modify metadata. This requires locally active thin-pool.
2015-10-07 16:10:03 +03:00
Check for enough space in thin-pool in command before creating new thin.
wiping: make libblkid detect all copies of the same signature if use_blkid_wiping=1 Some signatures are spread around the disk in several copies, mainly for backup. Make libblkid to detect these extra copies - there was missing "blkid_probe_step_back" fn call after successful wipe of previous signature copy. An example with FAT table which has copies: $ mkfs.vfat /dev/sda1 Before this patch: $ pvcreate /dev/sda1 WARNING: vfat signature detected on /dev/sda1 at offset 54. Wipe it? [y/n]: y Wiping vfat signature on /dev/sda1. Physical volume "/dev/sda1" successfully created With this patch applied: $ pvcreate /dev/sda1 WARNING: vfat signature detected on /dev/sda1 at offset 54.

vgimportclone: fix vgimportclone with -n to not add number unnecessarily to base VG name $ vgcreate vgA /dev/sda Volume group "vgA" successfully created $ dd if=/dev/sda of=/dev/sdb bs=1M $ dd if=/dev/sda of=/dev/sdc bs=1M (the new VG name is prefix of existing VG name) $ vgimportclone -n vg /dev/sdb (the new VG name is suffix of existing VG name) $ vgimportclone -n gA /dev/sdc Before this patch: ------------------ (we end up with "vg1" and "gA1" names with the "1" suffix which is not needed) $ vgs -o vg_name VG gA1 vg1 vgA With this patch applied: ------------------------ (we end up with "vg" and "gA" names as they're unique already and no extra suffix is added) $ # vgs -o vg_name VG gA vg vgA Of course, if the name supplied is not unique, the number is added correctly: $ dd if=/dev/sda of=/dev/sdb bs=1M $ vgimportclone -n vgA /dev/sdb $ vgs -o vg_name VG vgA vgA1
2015-10-12 12:11:34 +03:00
Fix vgimportclone with -n to not add number unnecessarily to base VG name.
vgimportclone: cleanup the script and remove dependency on awk, grep, cut and tr We can replace the expressions with awk/grep/cut/tr with --select now and more suitable reporting options and modes. Also, we don't need to check the temporary lvm.conf generated within vgimportclone script since we're generating it ourselves now using lvmconfig, not using sed anymore like it was before (so we can be pretty sure it's correct - we use lvmconfig now even for generating the lvm.conf itself).
2015-10-09 17:26:27 +03:00
Cleanup vgimportclone script and remove dependency on awk, grep, cut and tr.
report: add vg_missing_pv_count field We already have pv_count to report number of PVs that a VG has based on metadata. This patch exposes the information about how many of these PVs are missing which is also useful information for a VG. Wwe could count the sum of pv_missing reporting fields for each PV in the VG before, but the new field is practical when reporting VG as a whole and there's no need to process each PV from VG alone.
2015-10-09 17:20:29 +03:00
Add vg_missing_pv_count report field to report number of missing PVs in a VG.
report: identify LV hodling sanlock locks as 'private,lockd,sanlock' within lv_role report field Before this patch: $ lvs -a -o name,layout,role test/lvmlock LV Layout Role [lvmlock] linear public With this patch applied: $ lvs -a -o name,layout,role test/lvmlock LV Layout Role [lvmlock] linear private,lockd,sanlock
2015-10-08 14:44:21 +03:00
Properly identify internal LV holding sanlock locks within lv_role field.
raid: Add metadata dev information to reports. Add metadata_devices and seg_metadata_le_ranges report fields. Currently only defined for raid, but should probably be extended to all other segment types that don't report all their device usage in the 'devices' field.
2015-10-02 12:09:28 +03:00
Add metadata_devices and seg_metadata_le_ranges report fields for raid vols.
systemd: use {local,remote}-fs-pre.target instead of {local,remote}-fs.target We want most of our units to be started before any local/remote mount points are mounted - we used {local,remote}-fs.target for this purpose before, but it was not 100% correct as there's even {local,remote}-fs-pre.target special systemd unit reserved for this exact purpose. See also man 7 systemd.special and "local-fs-pre.target"/"remote-fs-pre.target" description.
2015-09-23 14:17:12 +03:00

2015-09-21 21:51:15 +03:00
Remove verbose message when rescanning an unchanged device. (2.02.119)
Add origin_uuid, mirror_log_uuid, move_pv_uuid, convert_lv_uuid report fields.
WHATS_NEW: commits cb8f29d1473d993d890387fe24331c9b9fe4713c - a54b4bba3578e371bb36ddb3b040a71825a62814
2015-09-21 15:28:41 +03:00
Add pool_lv_uuid, metadata_lv_uuid, data_lv_uuid reporting fields.
format-text: label: fix missing dev assignment for struct label in _text_pv_write When using lvm shell, some structures which are cached in memory may be reused. This happens for the struct label (a part of lvmcache_info structure) when lvmetad is used in which case the PV scan is not done that would normally overwrite these label structures in memory and making them up-to-date. This is all consequence of the fact that struct lvmcache_info and struct label are not always assigned in the same part of the code. For example, if lvmetad *is not* used, parts of the struct label are reassigned in label_read fn while struct lvmcache_info is created elsewhere. No part of the code reused struct label (and its "dev" field) before calling label_read fn. That's why the real bug is hidden when using lvm shell without lvmetad. However, with lvmetad and lvm shell, the situation is a bit different. The label_read fn is not called if lvmetad *is* used, hence the struct label may have ended up not initialized properly. There was missing assignment for the dev field in struct label in _text_pv_write fn which caused this problem to appear in lvm shell with lvmetad, for example: Before this patch: lvm> pvcreate /dev/sda Physical volume "/dev/sda" successfully created lvm> pvs /dev/sda PV VG Fmt Attr PSize PFree unknown device lvm2 --- 128.00m 128.00m With this patch applied: lvm> pvcreate /dev/sda Physical volume "/dev/sda" successfully created lvm> pvs /dev/sda PV VG Fmt Attr PSize PFree /dev/sda lvm2 --- 128.00m 128.00m Also, this problem had not appeared before changes introduced by commits e1a63905d14cc73352b905c70cb4084b7e521e33 through 3a6f91d7139119bea664050a957cbc21490398bc which, among other things, added proper label field type reporting. Before, label reporting was the same as using struct physical_volume which has its own dev field assigned and so this problem was not exposed.
2015-09-15 18:38:02 +03:00
Fix PV label processing failure after pvcreate in lvm shell with lvmetad.

man: Add all_man Makefile target. Use 'make all_man' to generate all man pages (regardless of configuration options) or 'make install_all_man' to install them.
2015-09-15 15:14:16 +03:00
Rename 'make install_full_man' to install_all_man and add all_man target.
vgimporeclone: use correct cache dir path Commit 00b36ef06acb15c82d7c9b37872753f02c638316 had a typo and missed '{' for shell variable, thus command used slightly different 'tmp' dir name for cache dir (with extra '}'). Such change was unnoticed until a recent fix in persistent filter, lvm2 missed to update cache file when --config was specified. The result was, /tmp dir was accumulating snap.XXXXX} dirs when running vgimportclose script.
2015-09-14 10:24:15 +03:00
Fix vgimportclone cache_dir path name (2.02.115).
thin: improve swapping of identifiers Since we may want to swap names when LVs are complex types, we cannot avoid doing full renames on both LV stacks. Temporarily use 'pvmove_tmeta' as unused name to prevent validation troubles.
2015-09-11 21:56:53 +03:00
Swapping of LV identifiers handles more complex LVs.
thin: lvconvert use passed PVs for _pmspare When PVs are given on 'lvconvert' respect them when converting volume to thin-pool and allocating i.e. _pmspare.
2015-09-11 21:56:02 +03:00
Use passed list of PVS when allocating space in lvconvert --thinpool.
Disallow usage of --stripe and --stripesize when creating cache pool.
cache: warn if caching causes troubles Certain stacks of cached LVs may have unexpected consequences. So add a warning function called when LV is cached to detect such caces and WARN user about them - the best we could do ATM.
2015-09-10 16:07:59 +03:00
Warn user when caching raid or thin pool data LV.
lib: when moving segtypes, move LV bits When we insert layer we also move status flag-bits for certain LV types, so internal volume_group structure remains consistent. (Perhaps it's misuse of 'insert_layer' function and we should have another similar function for this.) Basically we aim to maintain the same state as after reading fresh metadata out of volume group. Currently we when i.e. cache 'raid' LV - this should transfer 'raidLV' flag to _corigin LV and cache is no longer a raid. TODO: bits for stacked devices needs more exact rules.
2015-09-10 16:08:29 +03:00
When layering LV, move LV flags with segments.
dev-cache: ignore persistent cache if configuration changed Commit f6473baffc2d0b486b2aa941cf2681683026b3a5 introduced a new cmd->initialized variable to keep info about which parts of the cmd_context have been initialized. A part of this patch was also a change in refresh_filters fn which checks for cmd->initialized.filters variable and it does the filter refresh *only* if the filter has already been initialized before otherwise it's a NOOP (before, the refresh_filters also initialized filters as a side effect in case it had not been initialized before which was not quite correct). However, the commit f6473baffc2d0b486b2aa941cf2681683026b3a5 did not handle the case in which configuration changes either via --config argument or when configuration file changed and its timestamp was higher than the timestamp of the persistent cache file - the /etc/lvm/cache/.cache. This patch fixes this issue and it causes the init_filters fn in lvm_run_command fn to be called with proper value of "load_persistent_cache" switch even if the configuration changes, hence causing the persistent cache file to be ignored in this case.
2015-09-10 17:00:14 +03:00
Ignore persistent cache if configuration changed. (2.02.127)
WHATS_NEW: commit b77497cbd86a854add3ffa4ce09a35f165c0d2ba
2015-09-08 16:37:23 +03:00
Fix devices/filter to be applied before disk-accessing filters. (2.02.112)
makefiles: do not generate tags for everyone Create tags file only on request (make tags). Also clean file with 'make clean'.
2015-09-07 14:44:14 +03:00
Make tags only when requested via 'make tags'.
configure: support --disable-dependency-tracking One-time build may enjoy little speedup of build when dependencies are not calculated.
2015-09-07 14:57:38 +03:00
Configure supports --disable-dependency-tracking for one-time builds.
configure: relocate generated headers Relocate generated configure.h and lvm-version.h outside of compilable .c source tree. The reason is behind - when compiling in builddir != srcdir the generated file in lib/misc/configure.h was used for all compiled source file except ones located in lib/misc dir - those would have used configure.h file located in this dir - if there have existed one (i.e. from some other build) This problem was only visible, when srcdir == buildir was used before trying to use srcdri != builddir (as configure.h appeared then in srcdir).
2015-09-07 14:49:17 +03:00
Fix usage of configure.h when building in srcdir != builddir.

Version 2.02.130 - 5th September 2015
=====================================
dev-cache: fix use of uninitialized device status if reading outdated .cache record As part of fix that came with cf700151eba483aeedbf790fd66ce1c44e19c707, I forgot to add the check whether the result of stat was successful or not. This bug caused uninitialized buffer to be used for entries from .cache file which are no longer valid. This bug may have caused these uninitialized values to be used further, for example (see the unreal (2567,590944) representing major:minor pair): $ pvs /dev/abc: stat failed: No such file or directory Path /dev/abc no longer valid for device(2567,590944) PV VG Fmt Attr PSize PFree /dev/mapper/test lvm2 --- 104.00m 104.00m /dev/vda2 rhel lvm2 a-- 9.51g 0
2015-09-04 19:00:29 +03:00
Fix use of uninitialized device status if reading outdated .cache record.
lvcreate: restore missed --monitor Fix regression from d13239b0547e09def4b58b0f49bd0252f459d431. This patch reorganized whole command option parsing, however it has lost support to accept --monitor arg.
2015-08-27 18:19:09 +03:00
Restore support for --monitor option in lvcreate (2.02.112).
thin: do not flush when quering for thin percent Since we may easily get blocked when checking for percentage of thin-pool - do not flush and just show current values. This avoids holding VG locked when pool is overfilled.
2015-09-03 23:57:50 +03:00
Read thin-pool data and metadata percent without flush.
thin: detect unusable thins Try to detect thin-pool which my block lvm2 command from furher processing (i.e. lvextend). Check if pool is read-only or out-of-space and in this case thins will skipped from being scanned (so user may miss some PVs located on thin volumes).
2015-09-02 17:13:31 +03:00
Detect blocked thin-pool and avoid scanning their thin volumes.
filters: swap device_is_usable test Fix regression introduced with commit: 2fc126b00d83991c6a2f3ed9aa61457294a4c45e This commit has moved pv_min_size() test in front of device_is_usable(). However pv_min_size needs to open device, so it may have actually get blocked. So restore the original order and first validate dm device to be usable for open. It's worth to note that such check is not 'race-free', but it usually eliminates 99.99% of problems ;).
2015-09-02 17:08:30 +03:00
Check if dm device is usable before checking its size (2.02.116).
Extend parsing of cache_check version in configure.
lvmpolld: make lvpoll error messages visible Previously all stderr messages issued by spawned lvpoll command were reported as INFO only. This made all such messages invisible in syslog or lvmpolld log while running default configuration. All lvpoll stderr messages are loged with WARN priority now and lvpoll command exiting with retcode != 0 is logged with ERROR priority in syslog and lvmpolld log
2015-09-02 17:50:14 +03:00
Make lvpoll error messages visible in lvmpolld's stderr and in syslog.
man: Add install_full_man makefile target. 'make install_full_man' installs all the man pages regardless of which components were enabled when 'configure' was run.
2015-08-28 15:03:18 +03:00
Add 'make install_full_man' to install all man pages regardless of config.

===================================
vgdisplay: Drop error message for exported VGs. Originally when vgdisplay encountered an exported VG it issued a WARNING. Commit d6b1de30 replaced this with an error message but still exited with success (incorrect). A backtrace was recently added in commit b19380998739b9971d27845a70a78511c2335cb0. As vgdisplay already states that the VG is exported in its output, just drop these messages completely.
2015-08-26 23:11:46 +03:00
Drop error message when vgdisplay encounters an exported VG. (2.02.27)
make.tmpl: Mark internal sharedlib symbols local. Since commit 797c18d543947f4c2777b4dcf3ceff57cb55352b some internal symbols have been exported in shared libraries by mistake because 'local: *' got lost. Fix the shell script not to compare the whole filename with 'Base'
2015-08-26 15:36:23 +03:00
Fix shared library generation to stop exporting internal functions.(2.02.120)
cache: lvconvert accepts --cachemode for --cache All cache args could be specified when caching LV (means converting LV to cached). When --cachemode arg is given during cache-pool conversion, store it in the metadata. https://bugzilla.redhat.com/show_bug.cgi?id=1255184
2015-08-25 15:48:31 +03:00
Accept --cachemode with lvconvert.
cache: report cache pool attrs also for pools Since cache-pool actualy keeps info about caching, display this info for cache-pool LV as well (matches info for cache LV when cache-pool is asociated with it).
2015-08-25 16:07:41 +03:00
Fix and improve reporting properties of cache-pool.

Version 2.02.127 - 10th August 2015
===================================
commands: add new NO_METADATA_PROCESSING flag to selected commands When a command is flagged with NO_METADATA_PROCESSING flag, it means such command does not process any metadata and hence it doens't require lvmetad, lvmpolld and it can get away with no locking too. These are mostly simple commands (like lvmconfig/dumpconfig, version, types, segtypes and other builtin commands that do not process metadata in any way). At first, when lvm command is executed, create toolcontext without initializing connections (lvmetad,lvmpolld) and without initializing filters (which depend on connections init). Instead, delay this initialization until we know we need this. That is, until the lvm_run_command fn is called in which we know what the actual command to run is and hence we can avoid any connection, filter or locking initiliazation for commands that would not make use of it anyway. For all the other create_toolcontext calls, we keep the original behaviour - the filters and connections are initialized together with the toolcontext.
2015-07-30 11:48:28 +03:00
Do not init filters, locking, lvmetad, lvmpolld if command doesn't use it.
pre-release
2015-08-10 02:40:42 +03:00
Order fields in struct cmd_context more logically.
Add lock_type to lvmcache VG summary and info structs.
cache: fix regression causing some PVs to bypass filters This is a regression introduced by commit 6c0e44d5a2e82aa160d48e83992e7ca342bc4bdf which changed the way dev_cache_get fn works - before this patch, when a device was not found, it fired a full rescan to correct the cache. However, the change coming with that commit missed this full_rescan call, causing the lvmcache to still contain info about PVs which should be filtered now. Such situation may have happened by coincidence of using old persistent cache (/etc/lvm/cache/.cache) which does not reflect the actual state anymore, a device name/symlink which now points to a device which should be filtered and a fact we keep info about usable DM devices in .cache no matter what the filter setting is. This bug could be hidden though by changes introduced in commit f1a000a477558e157532d5f2cd2f9c9139d4f87c as it calls full_rescan earlier before this problem is hit. But we need to fix this anyway for the dev_cache_get to be correct if we happen to use the same code path again somewhere sometime. For example, simple reproducer was (before commit 1a000a477558e157532d5f2cd2f9c9139d4f87c): - /dev/sda contains a PV header with UUID y5PzRD-RBAv-7sBx-V3SP-vDmy-DeSq-GUh65M - lvm.conf: filter = [ "r|.*|" ] - rm -f .cache (to start with clean state) - dmsetup create test --table "0 8388608 linear /dev/sda 0" (8388608 is just the size of the /dev/sda device I use in the reproducer) - pvs (this will create .cache file which contains "/dev/disk/by-id/lvm-pv-uuid-y5PzRD-RBAv-7sBx-V3SP-vDmy-DeSq-GUh65M" as well as "/dev/mapper/test" and the target node "/dev/dm-1" - all the usable DM mappings (and their symlinks) get into the .cache file even though the filter "is set to "ignore all" - we do this - so far it's OK) - dmsetup remove test (so we end up with /dev/disk/by-id/lvm-pv-uuid-... pointing to the /dev/sda now since it's the underlying device containing the actual PV header) - now calling "pvs" with such .cache file and we get: $ pvs PV VG Fmt Attr PSize PFree /dev/disk/by-id/lvm-pv-uuid-y5PzRD-RBAv-7sBx-V3SP-vDmy-DeSq-GUh65M vg lvm2 a-- 4.00g 0 Even though we have set filter = [ "r|.*|" ] in the lvm.conf file!

Version 2.02.126 - 24th July 2015
=================================
tools: Streamline long option hyphen removal.
2015-07-24 21:45:49 +03:00
Fix long option hyphen removal. (2.02.122)
clvmd: Fix freeze if client dies holding locks. Simply running concurrent copies of 'pvscan | true' is enough to make clvmd freeze: pvscan exits on the EPIPE without first releasing the global lock. clvmd notices the client disappear but because the cleanup code that releases the locks is triggered from within some processing after the next select() returns, and that processing can 'break' after doing just one action, it sometimes never releases the locks to other clients. Move the cleanup code before the select. Check all fds after select(). Improve some debug messages and warn in the unlikely event that select() capacity could soon be exceeded.
2015-07-24 01:10:16 +03:00
Fix clvmd freeze if client disappears without first releasing its locks.
lvconvert: fix polling outside of core lvconvert Recent change to move the polling outside of core lvconvert code was wrongly using 'lv' and 'vg' structs which can't be used outside of the core code, which caused seg fault. Properly isolate all use of lv structs within the core of the lvconvert code, saving any information necessary, (esp lvid). After the core of lvconvert is done, use the saved information to do polling. FIXME: the need for is_merging_origin and is_merging_origin_thin in this patch is ugly, and a cleaner way should be found to deal with that than what is done here. Also it effectively removed all hacks in _lvconvert_merge_single performing ugly: VG reread, unlock, polling, lock sequence. Moreover all polling operations are postponed after all conversions are finished. lvm2 (while locking via lvmlockd) should now be able to run with or without lvmpolld while performing poll operations originating in lvconvert command. Signed-off-by: Ondrej Kozina <okozina@redhat.com>
2015-07-15 21:02:54 +03:00
Fix lvconvert segfaults while performing snapshots merge.
wiping: ignore errors during detection if use_blkid_wiping=1 and --force is used libblkid may return the list of signatures found, but it may not provide offset and size for each signature detected. This may happen in case signatures are mixed up or there are more, possibly overlapping, signatures found. Make lvm commands pass if such situation happens and we're using --force (or any stronger force method). For example: $ pvcreate /dev/sda1 Failed to get offset of the xfs_external_log signature on /dev/sda1. 1 existing signature left on the device. Aborting pvcreate on /dev/sda1. $ pvcreate --force /dev/sda1 Failed to get offset of the xfs_external_log signature on /dev/sda1. Physical volume "/dev/sda1" successfully created
2015-07-21 10:54:20 +03:00
Ignore errors during detection if use_blkid_wiping=1 and --force is used.
log: Add DM_ABORT_ON_INTERNAL_ERRORS lvm override. Recognise DM_ABORT_ON_INTERNAL_ERRORS in the lvm logging function as well as the default dm function it replaces.
2015-07-20 17:48:59 +03:00
Recognise DM_ABORT_ON_INTERNAL_ERRORS env var override in lvm logging fn.
alloc: Fix lvextend failure when varying stripes. A segfault was reported when extending an LV with a smaller number of stripes than originally used. Under unusual circumstances, the cling detection code could successfully find a match against the excess stripe positions and think it had finished prematurely leading to an allocation being pursued with a length of zero. Rename ix_offset to num_positional_areas and move it to struct alloc_state so that _is_condition() can obtain access to it. In _is_condition(), areas_size can no longer be assumed to match the number of positional slots being filled so check this newly-exposed num_positional_areas directly instead. If the slot is outside the range we are trying to fill, just ignore the match for now. (Also note that the code still only performs cling detection against the first segment of the LV.)
2015-07-16 01:12:54 +03:00
Fix alloc segfault when extending LV with fewer stripes than in first seg.
cache: handle policy_name separately Keep policy name separate from policy settings and avoid to mangling and demangling this string from same config tree. Ensure policy_name is always defined.
2015-07-15 12:06:40 +03:00
Fix handling of cache policy name.
cache: move setting of cache policy Set policy before saving 1st. metadata and avoid unnecessary reload. Fixes problem when we stored cache-pool without cache-policy set.
2015-07-14 10:57:34 +03:00
Set cache policy before with the first lvm2 cache pool metadata commit.
thin: fix warning for overprovisioning When lvm.conf is properly configure for auto resize of overprovisioned thin-pool volume, avoid showing any warning (2.02.124).
2015-07-13 12:08:49 +03:00
Fix detection of thin-pool overprovisioning (2.02.124).
lvmpolld: Fix segfault on 32 bit architectures Explicit conversions are needed to align writes and reads on the stack. int64_t is popped from stack while int was pushed.
2015-07-10 12:50:06 +03:00
Fix lvmpolld segfaults on 32 bit architectures.

2015-07-16 01:12:54 +03:00
Add lvmlockd lock_args validation to vg_validate.
lvmconf: fix ignored --startstopservices in lvmconf ... --mirrorservice on systemd If running lvmconf ... --startstopservice --mirrorservice in systemd environment, handle lvm2-cmirrord accordingly. A typo in the script caused the lvm2-cmirrord to not start/stop immediately, it was only enabled/disabled (so the --startstopservice was ignored in this case).
2015-07-09 11:35:41 +03:00
Fix ignored --startstopservices option if running lvmconf with systemd.

Version 2.02.124 - 3rd July 2015
================================
thin: move pool messaging from resume to suspend Existing messaging intarface for thin-pool has a few 'weak' points: * Message were posted with each 'resume' operation, thus not allowing activation of thin-pool with the existing state. * Acceleration skipped suspend step has not worked in cluster, since clvmd resumes only nodes which are suspended (have proper lock state). * Resume may fail and code is not really designed to 'fail' in this phase (generic rule here is resume DOES NOT fail unless something serious is wrong and lvm2 tool usually doesn't handle recovery path in this case.) * Full thin-pool suspend happened, when taken a thin-volume snapshot. With this patch the new method relocates message passing into suspend state. This has a few drawbacks with current API, but overal it performs better and gives are more posibilities to deal with errors. Patch introduces a new logic for 'origin-only' suspend of thin-pool and this also relates to thin-volume when taking snapshot. When suspend_origin_only operation is invoked on a pool with queued messages then only those messages are posted to thin-pool and actual suspend of thin pool and data and metadata volume is skipped. This makes taking a snapshot of thin-volume lighter operation and avoids blocking of other unrelated active thin volumes. Also fail now happens in 'suspend' state where the 'Fail' is more expected and it is better handled through error paths. Activation of thin-pool is now not sending any message and leaves upto a tool to decided later how to finish unfinished double-commit transaction. Problem which needs some API improvements relates to the lvm2 tree construction. For the suspend tree we do not add target table line into the tree, but only a device is inserted into a tree. Current mechanism to attach messages for thin-pool requires the libdm to know about thin-pool target, so lvm2 currently takes assumption, node is really a thin-pool and fills in the table line for this node (which should be ensured by the PRELOAD phase, but it's a misuse of internal API) we would possibly need to be able to attach message to 'any' node. Other thing to notice - current messaging interface in thin-pool target requires to suspend thin volume origin first and then send a create message, but this could not have any 'nice' solution on lvm2 side and IMHO we should introduce something like 'create_after_resume' message. Patch also changes the moment, where lvm2 transaction id is increased. Now it happens only after successful finish of kernel transaction id change. This change was needed to handle properly activation of pool, which is in the middle of unfinished transaction, and also this corrects usage of thin-pool by external apps like Docker.
2015-07-01 14:31:37 +03:00
Move sending thin pool messages from resume to suspend phase.
thin: check for overprovisioning
2015-07-03 16:31:31 +03:00

report: select: add handler to recognize fuzzy time specification Recognize date and time specification within selection criteria that is formulated in a more free-form way besides to the original basic YYYY-MM-DD HH:MM format that libdevmapper supports. Currently, this free-form format is recognized for lv_time field. Users are able to use expressions from this set: - weekday names ("Sunday" - "Saturday" or abbreviated as "Sun" - "Sat") - labels for points in time ("noon", "midnight") - labels for a day relative to current day ("today", "yesterday") - points back in time with relative offset from today (N is a number) ( "N" "seconds"/"minutes"/"hours"/"days"/"weeks"/"years" "ago") ( "N" "secs"/"mins"/"hrs" ... "ago") ( "N" "s"/"m"/"h" ... "ago") - time specification either in hh:mm:ss format or with AM/PM suffixes - month names ("January" - "December" or abbreviated as "Jan" - "Dec") For example: $ date Fri Jul 3 10:11:13 CEST 2015 $ lvmconfig --type full report/time_format time_format="%a %Y-%m-%d %T %z %Z [%s]" $ lvs LV VG Time lvol0 vg Fri 2014-08-22 21:25:41 +0200 CEST [1408735541] lvol2 vg Sun 2015-04-26 14:52:20 +0200 CEST [1430052740] root fedora Wed 2015-05-27 08:09:21 +0200 CEST [1432706961] swap fedora Wed 2015-05-27 08:09:21 +0200 CEST [1432706961] lvol1 vg Tue 2015-06-30 03:25:43 +0200 CEST [1435627543] lvol3 vg Tue 2015-06-30 14:52:23 +0200 CEST [1435668743] lvol6 vg Wed 2015-07-01 13:35:56 +0200 CEST [1435750556] lvol4 vg Thu 2015-07-02 12:12:02 +0200 CEST [1435831922] lvol5 vg Thu 2015-07-02 14:30:32 +0200 CEST [1435840232] $ lvs -S 'time=yesterday' LV VG Time lvol4 vg Thu 2015-07-02 12:12:02 +0200 CEST [1435831922] lvol5 vg Thu 2015-07-02 14:30:32 +0200 CEST [1435840232] $ lvs -S 'time since "June 30"' LV VG Time lvol1 vg Tue 2015-06-30 03:25:43 +0200 CEST [1435627543] lvol3 vg Tue 2015-06-30 14:52:23 +0200 CEST [1435668743] lvol6 vg Wed 2015-07-01 13:35:56 +0200 CEST [1435750556] lvol4 vg Thu 2015-07-02 12:12:02 +0200 CEST [1435831922] lvol5 vg Thu 2015-07-02 14:30:32 +0200 CEST [1435840232] $ lvs -S 'time since "noon June 30"' LV VG Time lvol3 vg Tue 2015-06-30 14:52:23 +0200 CEST [1435668743] lvol6 vg Wed 2015-07-01 13:35:56 +0200 CEST [1435750556] lvol4 vg Thu 2015-07-02 12:12:02 +0200 CEST [1435831922] lvol5 vg Thu 2015-07-02 14:30:32 +0200 CEST [1435840232] $ lvs -S 'time since "2 July 9AM"' LV VG Time lvol4 vg Thu 2015-07-02 12:12:02 +0200 CEST [1435831922] lvol5 vg Thu 2015-07-02 14:30:32 +0200 CEST [1435840232] $ lvs -S 'time since "2 July 1PM"' LV VG Time lvol5 vg Thu 2015-07-02 14:30:32 +0200 CEST [1435840232] ...and so on.

=================================
conf: make time format configurable Make it possible to define format for time that is displayed. The way the format is defined is equal to the way that is used for strftime function, although not all formatting options as used in strftime are available for LVM2 - the set is restricted (e.g. we do not allow newline to be printed). The lvm.conf comments contain the whole list that LVM2 accepts for time format together with brief description (copied from strftime man page). For example: (defaults used - the format is the same as used before this patch) $ lvs -o+time vg/lvol0 vg/lvol1 LV VG Attr LSize Time lvol0 vg -wi-a----- 4.00m 2015-06-25 16:18:34 +0200 lvol1 vg -wi-a----- 4.00m 2015-06-29 09:17:11 +0200 (using 'time_format = "@%s"' in lvm.conf - number of seconds since the Epoch) $ lvs -o+time vg/lvol0 vg/lvol1 LV VG Attr LSize Time lvol0 vg -wi-a----- 4.00m @1435241914 lvol1 vg -wi-a----- 4.00m @1435562231
2015-05-25 17:13:07 +03:00
Add report/time_format lvm.conf option to define time format for report.
makefiles: avoid bash == operator syntax, use = instead Commit e587b0677b705786a78f21bac1966621f70b2752 broke the build on systems where /bin/sh is Dash, for example. Origin patch by Ferenc Wágner <wferi@niif.hu> changed later to avoid using shell call, so makefile add 'server' target when one of metad or polld daemon is requested.
2015-06-26 10:00:16 +03:00
Fix makefile shell compare == when building lvmetad lvmpolld (2.02.120).
lvmconfig: add --type full to display full tree of settings The lvmconfig --type full is actually a combination of --type current and --type missing together with --mergedconfig options used. The overall outcome is a configuration tree with settings as LVM sees it when it looks for the values - that means, if the setting is defined in some config source (lvm.conf, --config, lvmlocal.conf or any profile that is used), the setting is used. Otherwise, if the setting is not defined in any part of the config cascade, the defaults are used. The --type full displays exactly this final tree with all the values defined, either coming from configuration tree or from defaults.
2015-06-25 11:51:30 +03:00
Add --type full to lvmconfig for full configuration tree view.
man: Add missing env vars to lvm man page.
2015-06-24 22:43:35 +03:00
Add undocumented environment variables to lvm man page. (2.02.119)
snapshot: add synchronization point Synchronize with udev logic before reusing device as snapshot. This patch tries to fix the problem with udev, where we manage to 'active' LV for clearing, then we deactivate such device and active again as member of 'origin&snapshot' tree all in 1 step. There needs to be a sync point where udev has time to remove all links, otherwise we race with scans and we may end-up with mysterious 'free' links in the system pointing to wrong dm names. This patch tries to fix failing topology cluster tests..
2015-06-24 16:12:43 +03:00
Add device synchronization point before activating a new snapshot.
lvmconfig: add --withspaces option We shouldn't be adding spaces by default in output as that may be be used already in scripts and especially for the eval in shell scripts where spaces are not allowed between key and value! Add --withspaces option to lvmconfig for pretty output with more space in for readability.
2015-06-24 14:14:30 +03:00
Add --withspaces to lvmconfig to add spaces in output for better readability.

thin: support unaligned size of external origin and thin pool With thin-pool kernel target module 1.13 it's now support usage of external origin with sizes which are not 'alligned' with chunk size of thin-pool. Enable lvm2 support for this and also fix reporting of data_percent usage for case sizes are not alligned.

Allow extension of reduced thin volumes with external origins.
Consider snapshot and origin LV as unusable if component devices suspended.
config: fix some settings incorrectly marked as CFG_DEFAULT_COMMENTED instead of CFG_DEFAULT_UNDEFINED and causing segfault This patch fixes segfault which was caused by incorrectly marking some settings CFG_DEFAULT_COMMENTED instead of CFG_DEFAULT_UNDEFINED - the ones which have NULL default value, hence they're really undefined. A regression caused by a98ceceb1d101f0b19a6115f406e23f13feab5ae. For example: $ lvmconfig log/file file="/a" Before this patch: $ lvmconfig --type diff Segmentation fault (core dumped) With this patch applied: $ lvmconfig --type diff log { file="/a" } The same applies for these settings: log/activate_file global/library_dir global/system_id_file <disk_area>/disk_area_id There were also other settings with NULL default value and marked as CFG_DEFAULT_COMMENTED instead of CFG_DEFAULT_UNDEFINED, but they were cfg_array config settings where the NULL value was not causing segfault (NULL == empty array).
2015-06-17 14:26:11 +03:00
Fix lvmconfig segfault on settings with undefined default value (2.02.120).

Fix test for AREA_PV when checking for failed mirrors.
scripts: activation generator: do not use --sysinit if lvmpolld used If lvmetad is not used, we generate lvm2-activation{-early,-net}.service systemd services to activate any VGs found on the system. So far we used --sysinit during this activation as polling was still forked off of the lvm activation command. This has changed with lvmpolld - we have proper lvmpolld systemd service now (activated via its socket unit). As such, we don't need to use --sysinit anymore during activation in systemd environment as polling was the only barrier to remove the need for --sysinit.
2015-05-21 12:07:07 +03:00
Do not use --sysinit in lvm2-activation{-early,-net}.service if lvmpolld used.

===============================
New LVM_LOG_FILE_EPOCH, LVM_EXPECTED_EXIT_STATUS env vars. Man page to follow.
Remove detailed content from lvm.conf man page: use lvmconfig instead.
config: Remove newly-exposed default settings.

2015-05-02 02:07:12 +03:00
Generate complete config files with lvmconfig or 'make generate'.
Also display info on deprecated config with lvmconfig --withcomments.
lvmconfig: add supporting code for handling deprecated settings This patch adds supporting code for handling deprecated settings. Deprecated settings are not displayed by default in lvmconfig output (except for --type current and --type diff). There's a new "--showdeprecated" lvmconfig option to display them if needed. Also, when using lvmconfig --withcomments, the comments with info about deprecation are displayed for deprecated settings and with lvmconfig --withversions, the version in which the setting was deprecated is displayed in addition to the version of introduction. If using --atversion with a version that is lower than the one in which the setting was deprecated, the setting is then considered as not deprecated (simply because at that version it was not deprecated). For example: $ lvmconfig --type default activation activation { ... raid_region_size=512 ... } $ lvmconfig --type default activation --showdeprecated activation { ... mirror_region_size=512 raid_region_size=512 ... } $ lvmconfig --type default activation --showdeprecated --withversions activation { ... # Available since version 1.0.0. # Deprecated since version 2.2.99. mirror_region_size=512 # Available since version 2.2.99. raid_region_size=512 ... } $ lvmconfig --type default activation --showdeprecated --withcomments activation { ... # Configuration option activation/mirror_region_size. # This has been replaced by the activation/raid_region_size # setting. # Size (in KB) of each copy operation when mirroring. # This configuration option is deprecated. mirror_region_size=512 # Configuration option activation/raid_region_size. # Size in KiB of each raid or mirror synchronization region. # For raid or mirror segment types, this is the amount of # data that is copied at once when initializing, or moved # at once by pvmove. raid_region_size=512 ... } $ lvmconfig --type default activation --withcomments --atversion 2.2.98 activation { ... # Configuration option activation/mirror_region_size. # Size (in KB) of each copy operation when mirroring. mirror_region_size=512 ... }
2015-04-30 18:40:24 +03:00
Display version since which config is deprecated in lvmconfig --withversions.
Add --showdeprecated to lvmconfig to also display deprecated settings.

config: consolidate CFG_UNSUPPORTED and CFG_ADVANCED settings These settings are in the "unsupported" group: devices/loopfiles log/activate_file metadata/disk_areas (section) metadata/disk_areas/<disk_area> (section) metadata/disk_areas/<disk_area>/size metadata/disk_areas/<disk_area>/id These settings are in the "advanced" group: devices/dir devices/scan devices/types global/proc activation/missing_stripe_filler activation/mlock_filter metadata/pvmetadatacopies metadata/pvmetadataignore metadata/stripesize metadata/dirs Also, this patch causes the --ignoreunsupported and --ignoreadvanced switches to be honoured for all config types (lvmconfig --type). By default, the --type current and --type diff display unsupported settings, the other types ignore them - this patch also introduces --showunsupported switch for all these other types to display even unsupported settings in their output if needed.
2015-04-29 17:07:52 +03:00
Add --showunsupported to lvmconfig to also display unsupported settings.

python: python 3 compat patch for lvm2 As provided by rhbz: 1136366
2014-09-02 17:42:01 +04:00
Make python bindings usable with python3 (and compatible with 2.6 & 2.7).
lvmconfig: add --type list and -l|--list lvmconfig --type list displays plain list of configuration settings. Some of the existing decorations can be used (--withsummary and --withversions) as well as existing options/switches (--ignoreadvanced, --ignoreunsupported, --ignorelocal, --atversion). For example (displaying only "config" section so the list is not long): $lvmconfig --type list config config/checks config/abort_on_errors config/profile_dir $ lvmconfig --type list --withsummary config config/checks - If enabled, any LVM configuration mismatch is reported. config/abort_on_errors - Abort the LVM process if a configuration mismatch is found. config/profile_dir - Directory where LVM looks for configuration profiles. $ lvmconfig -l config config/checks - If enabled, any LVM configuration mismatch is reported. config/abort_on_errors - Abort the LVM process if a configuration mismatch is found. config/profile_dir - Directory where LVM looks for configuration profiles. $ lvmconfig --type list --withsummary --withversions config config/checks - If enabled, any LVM configuration mismatch is reported. [2.2.99] config/abort_on_errors - Abort the LVM process if a configuration mismatch is found. [2.2.99] config/profile_dir - Directory where LVM looks for configuration profiles. [2.2.99] Example with --atversion (displaying global section): $ lvmconfig --type list global global/umask global/test global/units global/si_unit_consistency global/suffix global/activation global/fallback_to_lvm1 global/format global/format_libraries global/segment_libraries global/proc global/etc global/locking_type global/wait_for_locks global/fallback_to_clustered_locking global/fallback_to_local_locking global/locking_dir global/prioritise_write_locks global/library_dir global/locking_library global/abort_on_internal_errors global/detect_internal_vg_cache_corruption global/metadata_read_only global/mirror_segtype_default global/raid10_segtype_default global/sparse_segtype_default global/lvdisplay_shows_full_device_path global/use_lvmetad global/thin_check_executable global/thin_dump_executable global/thin_repair_executable global/thin_check_options global/thin_repair_options global/thin_disabled_features global/cache_check_executable global/cache_dump_executable global/cache_repair_executable global/cache_check_options global/cache_repair_options global/system_id_source global/system_id_file $ lvmconfig --type list global --atversion 2.2.50 global/umask global/test global/units global/suffix global/activation global/fallback_to_lvm1 global/format global/format_libraries global/segment_libraries global/proc global/locking_type global/wait_for_locks global/fallback_to_clustered_locking global/fallback_to_local_locking global/locking_dir global/library_dir global/locking_library

Add lvmconfig -l|--list as shortcut for lvmconfig --type list --withsummary.
Add lvmconfig --type list to display plain list of configuration settings.
config: Introduce lvmconfig. 'lvm dumpconfig' now does a lot more than just dumping configuration information and is no longer only a support tool. Users now need to run it to find out about configuration information that has been removed from the lvm.conf man page so we need to promote this to full command line status as 'lvmconfig'. Also accept 'lvm config' and mention it in the usage information of lvmconf (which should also get merged in eventually).
2015-04-28 19:00:37 +03:00
Introduce lvmconfig as the preferred form of 'lvm dumpconfig'.
report: add lv_ancestors and lv_descendants reporting fields Show full chain of ancestors and descendants for snapshots (both thick and thin - in case of thick, the "ancestor" field is actually equal to "origin" field as snapshots can't be chained for thick snapshots). These fields display current state as it is, they do not display any history! If the snapshot chain is broken in the middle, we don't report the historical origin (this is going to be a part of another patch and a different set of fields or just a switch for existing fields to show ancestors and descendants with history included). For example: (origin --> snapshot) lvol1 --> lvol2 --> lvol3 --> lvol4 \ --> lvol5 --> lvol6 --> lvol7 --> lvol8 $ lvs -o name,pool_lv,origin,ancestors,descendants vg LV Pool Origin Ancestors Descendants lvol1 pool lvol2,lvol3,lvol4,lvol5,lvol6,lvol7,lvol8 lvol2 pool lvol1 lvol1 lvol3,lvol4,lvol5,lvol6,lvol7,lvol8 lvol3 pool lvol2 lvol2,lvol1 lvol4 lvol4 pool lvol3 lvol3,lvol2,lvol1 lvol5 pool lvol2 lvol2,lvol1 lvol6,lvol7,lvol8 lvol6 pool lvol5 lvol5,lvol2,lvol1 lvol7,lvol8 lvol7 pool lvol6 lvol6,lvol5,lvol2,lvol1 lvol8 lvol8 pool lvol7 lvol7,lvol6,lvol5,lvol2,lvol1
2015-04-24 12:51:52 +03:00
Add lv_ancestors and lv_descendants reporting fields.
dumpconfig: add --ignorelocal When generating a sample lvm.conf file, we don't want to include the "local" section, which is kept in lvmlocal.conf.
2015-04-21 22:53:54 +03:00
Add --ignorelocal option to dumpconfig to ignore the local section.
WHATS_NEW: update for various commits add info for various commits, most significant were: - toollib: close connection to lvmetad after fork (fe30658a4d5fe4e4e6bb346c9c9ee7142a98f49d) - toollib: do not spawn polling in lv_change_activate (c26d81d6e6939906729d91fae83cd8bbdd743bb7) - pvmove: split pvmove_update_metadata function (65623b63a20a221b48dfd87455dc77f5ac0c6bf4) - lvconvert: move poll code in before refactoring (5190f566055ab4584772b1288fd8cbf69565eb4a) - pvmove: move poll code in before refactoring (a098aa419f5be5d8f805ab6dc747770e58a4b7b1)
2015-04-20 11:31:43 +03:00
Close connection to lvmetad after fork.
Make lvchange able to resume background pvmove polling again.
Split pvmove update metadata fn in an initial one and a subsequent one.
Refactor shared pvmove and lvconvert code into new _poll files.
dumpconfig: add --unconfigured option Using this option, default string values that are configurable are printed as unconfigured values, e.g. "@CONFDIR@" instead of "/etc".
2015-04-17 19:31:16 +03:00
Add --unconfigured option to dumpconfig to print strings unconfigured.
refactor: dumpconfig: keep --withcomments to display full comment and use --withsummary for one line summary
2015-04-29 11:53:25 +03:00
Add --withsummary option to dumpconfig to print first line - summary comment.
pre-release
2015-05-02 03:41:17 +03:00
Use number of device holders to help choose between duplicate PVs.
Try to make lvmetad and non-lvmetad duplicate PV handling as similar as poss.
Issue warnings about duplicate PVs discovered by lvmetad.
Track alternative devices with matching PVIDs in lvmetad.
blkdeactivate: check for lvm binary and skip LVM processing if not present This removes dependency on lvm binary - if it's not present, all LVM processing is skipped (shouldn't normally happen because if lvm binary is missing then there's obviously nothing that would activate it, but let's make sure). Without this tight dependency on lvm, the blkdeactivate script can be packaged with libdevmapper/dmsetup (in contrast to lvm as it was before) and as such the script can still be used to handle other DM devices.
2015-04-14 14:35:11 +03:00
Check for lvm binary in blkdeactivate and skip LVM processing if not present.
WHATS_NEW: previous commit f814d7wq
2015-04-13 16:49:25 +03:00
Add --enable-halvm and --disable-halvm options to lvmconf script.
lvmconf: add --enable-halvm, --disable-halvm, --services, --mirrorservice, --startstopservices options and use proper global/use_lvmetad default value This patch adds new options to lvmconf: --enable-halvm (just like --enable-cluster, but configure LVM for use in HA LVM - meaning disabling lvmetad and making sure we have locking_type=1) --disable-halvm (just like --disable-cluster, but configure LVM back from HA LVM - meaning enabling lvmetad if it's enabled by default and making sure we have default locking type set) --services (causes clvmd and lvmetad services to be enabled or disabled appropriately and conforming to the changes in lvm configuration we've just made with lvmconf) --mirrorservice (in addition to clvmd and lvmetad services, also enable or disable cmirrord service appropriately; this is a separate option because cmirrord is optional and it doesn't need to be always enabled when clvmd is enabled) --startstopservices (in addition to enabling or disabling services, start and stop these services immediately) These options are supposed to help users to make their system ready for cluster with clvmd (active-active) or HA LVM (active-passive) use while lvmconf script can handle services as well so users don't need to bother about setting them manually. Also, before this patch, we hardcoded global/use_lvmetad=0 as default value in lvmconf script. Howeverm this default may change by just flipping the value in config_settings.h and we may forget to edit the lvmconf. It's better to use lvm dumpconfig --type default global/use_lvmetad to get the actual default value and use this one instead of hardcoded one.
2015-04-13 16:27:17 +03:00
Add --services, --mirrorservice and --startstopservices option to lvmconf.
Use proper default value of global/use_lvmetad when processing lvmconf script.
alloc: Respect cling_tag_list in contig alloc. When performing initial allocation (so there is nothing yet to cling to), use the list of tags in allocation/cling_tag_list to partition the PVs. We implement this by maintaining a list of tags that have been "used up" as we proceed and ignoring further devices that have a tag on the list. https://bugzilla.redhat.com/983600
2015-04-11 03:55:24 +03:00
Respect allocation/cling_tag_list during intial contiguous allocation.
alloc: Add A_PARTITION_BY_TAGS to avoid sharing. Add A_PARTITION_BY_TAGS set when allocated areas should not share tags with each other and allow _match_pv_tags to accept an alternative list of tags. (Not used yet.)
2015-04-10 23:57:52 +03:00
Add A_PARTITION_BY_TAGS set when allocated areas should not share tags.
pre-release
2015-05-02 03:41:17 +03:00
Make changes persist with python addTag/removeTag.
cache: Set correct vgid when changing PV header. pv_write is called both to write orphans and to rewrite PV headers of PVs in VGs. It needs to select the correct VG id so that the internal cache state gets updated correctly. It only affected commands that involved further steps after the pv_write and was often masked because the metadata would be re-read off disk and correct itself. "Incorrect metadata area header checksum" warnings appeared. Example: Create vg1 containing dev1, dev2 and dev3. Hide dev1 and dev2 from the system. Fix up vg1 with vgreduce --removemissing. Bring back dev1 and dev2. In a single operation reinstate dev1 and dev2 into vg1 (vgextend). Done as separate operations (automatically fix-up dev1 and dev2 as orphans, then vgextend) it worked, but done all in one go the internal cache got corrupted and warnings about checksum errors appeared.
2015-04-09 23:13:55 +03:00
Set correct vgid when updating cache when writing PV metadata.
clvmd: singlenode signals only when lock changes There is no benefit in waking-up all the waiters when there is no actual change in lock state. This avoid some unnecessarily ping-pong effects like: Resource V_LVMTEST15724vg retrying lock in mode:WRITE... Resource V_LVMTEST15724vg already locked lockid=40, mode:WRITE Resource V_LVMTEST15724vg retrying lock in mode:WRITE... Resource V_LVMTEST15724vg already locked lockid=40, mode:WRITE
2015-04-09 00:12:29 +03:00
More efficient clvmd singlenode locking emulation.
pre-release
2015-05-02 03:41:17 +03:00
Reject lvcreate -m with raid4/5/6 to avoid unexpected layout.
lvmcache: skip drop when vg_write lock is not held Commit 80f4b4b8039a88dfa2648a9b5bb5e16f41b81f87 introduced undesirable side-effects for lvm2app user which happens to be our own python binding. It appear obtaing pvs list keeps global lock. So restricting this to VG_GLOBAL READ locks and skip the drop skip if WRITE lock is held.
2015-04-02 13:42:18 +03:00
Don't skip invalidation of cached orphans if vg write lck is held (2.02.118).
alloc: Log PV tags when reserving areas.
2015-03-27 00:13:26 +03:00
Log relevant PV tags when using cling allocation.
datastruct: Add str_list_add_list.
2015-03-26 21:30:37 +03:00
Add str_list_add_list() to combine two lists.
metadata: process_each_lv_in_vg: get the list of LVs to process first, then do the processing This avoids a problem in which we're using selection on LV list - we need to do the selection on initial state and not on any intermediary state as we process LVs one by one - some of the relations among LVs can be gone during this processing. For example, processing one LV can cause the other LVs to lose the relation to this LV and hence they're not selectable anymore with the original selection criteria as it would be if we did selection on inital state. A perfect example is with thin snapshots: $ lvs -o lv_name,origin,layout,role vg LV Origin Layout Role lvol1 thin,sparse public,origin,thinorigin,multithinorigin lvol2 lvol1 thin,sparse public,snapshot,thinsnapshot lvol3 lvol1 thin,sparse public,snapshot,thinsnapshot pool thin,pool private $ lvremove -ff -S 'lv_name=lvol1 || origin=lvol1' Logical volume "lvol1" successfully removed The lvremove command above was supposed to remove lvol1 as well as all its snapshots which have origin=lvol1. It failed to do so, because once we removed the origin lvol1, the lvol2 and lvol3 which were snapshots before are not snapshots anymore - the relations change as we're processing these LVs one by one. If we do the selection first and then execute any concrete actions on these LVs (which is what this patch does), the behaviour is correct then - the selection is done on the *initial state*: $ lvremove -ff -S 'lv_name=lvol1 || origin=lvol1' Logical volume "lvol1" successfully removed Logical volume "lvol2" successfully removed Logical volume "lvol3" successfully removed Similarly for all the other situations in which relations among LVs are being changed by processing the LVs one by one. This patch also introduces LV_REMOVED internal LV status flag to mark removed LVs so they're not processed further when we iterate over collected list of LVs to be processed. Previously, when we iterated directly over vg->lvs list to process the LVs, we relied on the fact that once the LV is removed, it is also removed from the vg->lvs list we're iterating over. But that was incorrect as we shouldn't remove LVs from the list during one iteration while we're iterating over that exact list (dm_list_iterate_items safe can handle only one removal at one iteration anyway, so it can't be used here).
2015-03-16 19:10:21 +03:00
Fix LV processing with selection to always do the selection on initial state.

Version 2.02.118 - 23rd March 2015
==================================
cache: Store metadata size and checksum. Refactor the recent metadata-reading optimisation patches. Remove the recently-added cache fields from struct labeller and struct format_instance. Instead, introduce struct lvmcache_vgsummary to wrap the VG information that lvmcache holds and add the metadata size and checksum to it. Allow this VG summary information to be looked up by metadata size + checksum. Adjust the debug log messages to make it clear when this shortcut has been successful. (This changes the optimisation slightly, and might be extendable further.) Add struct cached_vg_fmtdata to format-specific vg_read calls to preserve state alongside the VG across separate calls and indicate if the details supplied match, avoiding the need to read and process the VG metadata again.
2015-03-19 02:43:02 +03:00
Store metadata size + checksum in lvmcache and add struct lvmcache_vgsummary.
pvs: Hide inaccessible clustered PVs. Inaccessible clustered PVs can be hidden from pvs -a in the same way as foreign PVs, rather than showing them as if they do not belong to a VG.
2015-03-19 02:31:46 +03:00
Remove inaccessible clustered PVs from 'pvs -a'.
cache: Retain orphans while global lock held. Fixes segfault when 'pvs' encounters two different PVs sharing the same uuid but one an orphan, the other in a VG. If VG_GLOBAL is held, there seems no point in doing a full scan more than once. If undesirable side-effects show up, we can try restricting this to VG_GLOBAL READ locks. The original code dates back to 2.02.40.
2015-03-19 02:20:09 +03:00
Don't invalidate cached orphan information while global lock is held.
pvscan: check sysfs dev entry before rescan When pvscan --cache --major --minor command is issued from udev REMOVE event, it basically resulted into a whole device scan since the device was missing. So avoid such scan and first check via /sysfs (when available) if such device actually exists.
2015-03-18 18:19:58 +03:00
Avoid rescan of all devices when requested pvscan for removed device.
config: use timestamp with nanosecond precision Since kernel 2.6 we can use more precise timestamping, so e.g. we could better recognize configs are slightly older then generated .cache file.
2015-03-18 12:59:41 +03:00
Measure configuration timestamps with nanoseconds when available.
lvchange: disable persistent minors for pools There is no reason to support persistent major/minor numbers for pool volumes - it's only meant to be supported for filesystems (since i.e. nfs may need to keep volume on a persistent device node.) Support for pools is now explicitely disabled and documented.
2015-03-17 11:44:26 +03:00
Disable lvchange of major and minor of pool LVs.
lvmetad: pvscan: do not scan and read ignored MDAs from PVs Metadata areas which are marked as ignored should not be scanned and read during pvscan --cache. Otherwise, this can cause lvmetad to cache out-of-date metadata in case other PVs with fresh metadata are missing by chance. Make this to work like in non-lvmetad case where the behaviour would be the same as if the PV was orphan (in case we have no other PVs with valid non-ignored metadata areas).
2015-03-16 19:00:36 +03:00
Fix pvscan --cache to not scan and read ignored metadata areas on PVs.
systemd: blk-availability.service: add After=iscsi-shutdown.service The iscsi-shutdown.service is the one responsible for logging out iscsi sessions so blk-availability.service (running the blkdeactivate script) should be run before that on shutdown (so we need to use After=iscsi-shutdown.service because "After" relates to starting the service and the opposite order is automatically applied on stopping the service at shutdown).
2015-03-13 14:05:47 +03:00
Add After=iscsi-shutdown.service to blk-availability.service systemd unit.
WHATS_NEW vgconvert -M fix
2015-03-10 17:38:43 +03:00
Disallow vgconvert from changing metadata format when lvmetad is used.
lib: drop unneeded vg_read call Since we take a lock inside vg_lock_newname() and we do a full detection of presence of vgname inside all scanned labels, there is no point to do this for second time to be sure there is no such vg. The only side-effect of such call would be a full validation of some already exising VG metadata - but that's not the task for vgcreate when create a new VG. This call noticable reduces number of scans during 'vgcreate'.
2015-03-06 12:22:33 +03:00
Don't do a full read of VG when creating a new VG with an existing name.
cache: Store metadata size and checksum. Refactor the recent metadata-reading optimisation patches. Remove the recently-added cache fields from struct labeller and struct format_instance. Instead, introduce struct lvmcache_vgsummary to wrap the VG information that lvmcache holds and add the metadata size and checksum to it. Allow this VG summary information to be looked up by metadata size + checksum. Adjust the debug log messages to make it clear when this shortcut has been successful. (This changes the optimisation slightly, and might be extendable further.) Add struct cached_vg_fmtdata to format-specific vg_read calls to preserve state alongside the VG across separate calls and indicate if the details supplied match, avoiding the need to read and process the VG metadata again.
2015-03-19 02:43:02 +03:00
Reduce amount of VG metadata parsing when looking for vgname on a PV.
lib: avoid reparsing same metadata When reading VG mda from multiple PVs - do all the validation only when mda is seen for the first time and when mda checksum and length is same just return already existing VG pointer. (i.e. using 300PVs for a VG would lead to create and destroy 300 config trees....)
2012-03-26 15:35:26 +04:00
Avoid reparsing same metadata when reading same metadata from multiple PVs.
devices: avoid extra open() syscall If the device is already opened by lvm's device cache, avoid extra syscall opening devices for obtaining its size.
2015-03-03 17:37:17 +03:00
Save extra device open/close when scanning device for size.
report: fix seg_monitor field to display monitoring status for thick snapshots and mirrors The seg_monitor did not display monitored status for thick snapshots and mirrors (with mirror log *not* mirrored). The seg monitor did work correctly even before for other segtypes - thins and raids. Before (mirrors and snapshots, only mirrors with mirrored log properly displayed monitoring status): [0] f21/~ # lvs -a -o lv_name,lv_layout,lv_role,seg_monitor vg LV Layout Role Monitor mirror mirror public [mirror_mimage_0] linear private,mirror,image [mirror_mimage_1] linear private,mirror,image [mirror_mlog] linear private,mirror,log mirror_with_mirror_log mirror public monitored [mirror_with_mirror_log_mimage_0] linear private,mirror,image [mirror_with_mirror_log_mimage_1] linear private,mirror,image [mirror_with_mirror_log_mlog] mirror private,mirror,log monitored [mirror_with_mirror_log_mlog_mimage_0] linear private,mirror,image [mirror_with_mirror_log_mlog_mimage_1] linear private,mirror,image thick_origin linear public,origin,thickorigin thick_snapshot linear public,snapshot,thicksnapshot With this patch applied (monitoring status displayed for all mirrors and snapshots): [0] f21/~ # lvs -a -o lv_name,lv_layout,lv_role,seg_monitor vg LV Layout Role Monitor mirror mirror public monitored [mirror_mimage_0] linear private,mirror,image [mirror_mimage_1] linear private,mirror,image [mirror_mlog] linear private,mirror,log mirror_with_mirror_log mirror public monitored [mirror_with_mirror_log_mimage_0] linear private,mirror,image [mirror_with_mirror_log_mimage_1] linear private,mirror,image [mirror_with_mirror_log_mlog] mirror private,mirror,log monitored [mirror_with_mirror_log_mlog_mimage_0] linear private,mirror,image [mirror_with_mirror_log_mlog_mimage_1] linear private,mirror,image thick_origin linear public,origin,thickorigin thick_snapshot linear public,snapshot,thicksnapshot monitored

pre-release
2015-03-04 16:49:51 +03:00
Version 2.02.117 - 4th March 2015
=================================
Add CFG_DISABLED for new system ID config settings that must not yet be used.
archives: Preserve format type in file. format_text processes both lvm2 on-disk metadata and metadata read from other sources such as backup files. Add original_fmt field to retain the format type of the original metadata. Before this patch, /etc/lvm/archives would contain backups of lvm1 metadata with format = "lvm2" unless the source was lvm1 on-disk metadata.
2015-03-04 03:30:26 +03:00
Preserve original format type field when processing backup files.
initscripts: lvm2-monitor: implement status action Two new functions added in the init script: rh_status and rh_status_q. First one to be used in status() and second one to be used in start(), stop(), force_stop(). Check for 'dmeventd' added and print list of lvs being monitored in status().
2015-02-27 17:38:34 +03:00
Implement status action for lvm2-monitor initscript to display monitored LVs.
lvchange: Allow -pr to change kernel only.
2015-02-27 16:38:26 +03:00
Allow lvchange -p to change kernel state only if metadata state differs.
report: fix handling of reports with pure label fields Two problems fixed by this patch: - PV tags were not recognized at all when using them with pvs report that has only label fields (regression since 2.02.105) - incorrect persistent .cache file to be generated after pvs report that has only label fields (regression since 2.02.106) These bugs come from the transition from process_each_pv to process_each_label introduced by commit 67a7b7a87da65b2350f975272e581be5f41976e0 and commit 490226fc475232e0b158cf9fdc8670a663da4efe and related.
2015-02-27 15:32:52 +03:00
Fix incorrect persistent .cache after report with label fields only (2.02.106).
Reinstate PV tag recognition for pvs if reporting label fields only (2.02.105).
WHATS_NEW: vgimport with lvmetad
2015-02-25 21:30:00 +03:00
Rescan devices before vgimport with lvmetad so exported VG is seen.
cmirror: Adjust region size to work around CPG msg limit to avoid hang. cmirror uses the CPG library to pass messages around the cluster and maintain its bitmaps. When a cluster mirror starts-up, it must send the current state to any joining members - a checkpoint. When mirrors are large (or the region size is small), the bitmap size can exceed the message limit of the CPG library. When this happens, the CPG library returns CPG_ERR_TRY_AGAIN. (This is also a bug in CPG, since the message will never be successfully sent.) There is an outstanding bug (bug 682771) that is meant to lift this message length restriction in CPG, but for now we work around the issue by increasing the mirror region size. This limits the size of the bitmap and avoids any issues we would otherwise have around checkpointing. Since this issue only affects cluster mirrors, the region size adjustments are only made on cluster mirrors. This patch handles cluster mirror issues involving pvmove, lvconvert (from linear to mirror), and lvcreate. It also ensures that when users convert a VG from single-machine to clustered, any mirrors with too many regions (i.e. a bitmap that would be too large to properly checkpoint) are trapped.
2015-02-25 23:42:15 +03:00
Fix hang by adjusting cluster mirror regionsize, avoiding CPG msg limit.
cache: Fix a segfault when passing --cachepolicy without --cachesettings.
2015-02-24 13:36:30 +03:00
Do not crash when --cachepolicy is given without --cachesettings.
systemid: Extend --foreign to reporting commands. Add --foreign to the remaining reporting and display commands plus vgcfgbackup. Add a NEEDS_FOREIGN_VGS flag for vgimport to always set --foreign. If lvmetad is being used with --foreign, scan foreign VGs (currently implemented as a full PV scan). Handle these things centrally in lvmcmdline.c. Also allow lvchange and vgchange -an/-aln to deactivate any foreign LVs that happen to be active if something went wrong. Remember to set the system ID when creating a new VG in vgsplit.
2015-02-24 02:41:38 +03:00
Add NEEDS_FOREIGN_VGS flag to vgimport so --foreign is always supplied.
Add --foreign to the 6 display and reporting tools and vgcfgbackup.
lvm1: Reenable sys ID. Move the lvm1 sys ID into vg->lvm1_system_id and reenable the #if 0 LVM1 code. Still display the new-style system ID in the same reporting field, though, as only one can be set. Add a format feature flag FMT_SYSTEM_ON_PVS for LVM1 and disallow access to LVM1 VGs if a new-style system ID has been set. Treat the new vg->system_id as const.
2015-02-24 02:03:52 +03:00
Install /etc/lvm/lvmlocal.conf template with local section for systemid.
pre-release
2015-03-04 16:49:51 +03:00
Record creation_host_system_id in lvm2 metadata (never set yet).
config: Reinstate recursive tags setting. In 2.02.99, _init_tags() inadvertently began to ignore the dm_config_tree struct passed to it. "tags" sections are not merged together, so the "tags" section in the main config file was being processed repeatedly and other "tags" sections were ignored.
2015-02-23 20:40:58 +03:00
Reinstate recursive config file tag section processing. (2.02.99)
pre-release
2015-03-04 16:49:51 +03:00
Add 'lvm systemid' to display the current system ID (never set yet).
configure: typo in configure --with-default-raid10-segtype causing it to be unrecognized AC_ARG_WITH(default-raid10r-segtype --> AC_ARG_WITH(default-raid10-segtype (...raid10r... --> ...raid10... - extra "r")
2015-02-19 18:17:19 +03:00
Fix configure to properly recognize --with-default-raid10-segtype option.
filters: no need to refresh filters/rescan if no signature is wiped during pvcreate at all Before, we refreshed filters and we did full rescan of devices if we passed through wiping (wipe_known_signatures fn call). However, this fn returns success even if no signatures were found and so nothing was wiped. In this case, it's not necessary to do the filter refresh/rescan of devices as nothing changed clearly. This patch exports number of wiped signatures from all the wiping functions below. The caller (_pvcreate_check) then checks whether any wiping was done at all and if not, no refresh/rescan is done, saving some time and resources.
2015-02-17 11:46:34 +03:00
Do not refresh filters/rescan if no signature is wiped during pvcreate.
pvcreate: switch to "none" dev-ext source during pvcreate pvcreate code path executes signature wiping if there are any signatures found on device to prepare the device for PV. When the signature is wiped, the WATCH udev rule triggers the event which then updates udev database with fresh info, clearing the old record about previous signature. However, when we're using udev db as dev-ext source, we'd need to wait for this WATCH-triggered event. But we can't synchronize against such events (at least not at this moment). Without this sync, if the code continues, the device could still be marked as containing the old signature if reading udev db. This may end up even with the device to be still filtered, though the signature is already wiped. This problem is then exposed as (an example with md components): $ mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda /dev/sdb --run $ mdadm -S /dev/md0 $ pvcreate -y /dev/sda Wiping linux_raid_member signature on /dev/sda. /dev/sda: Couldn't find device. Check your filters? $ echo $? 5 So we need to temporarily switch off "udev" dev-ext source here in this part of pvcreate code until we find a way how to sync with WATCH events. (This problem does not occur with signature wiping which we do on newly created LVs since we already handle this properly with our udev flags - the LV_NOSCAN/LV_TEMPORARY flag. But we can't use this technique for non-dm devices to keep WATCH rule under control.)
2015-02-16 16:43:03 +03:00
Enforce none external dev info for wiping during pvcreate to avoid races.
pre-release
2015-03-04 16:49:51 +03:00
Add global/system_id_source and system_id_file to lvm.conf (disabled).
WHATS_NEW for system_id
2015-02-13 19:27:17 +03:00
Add support for VG system_id to control host access to VGs.
vgextend: Use process_each_vg. Tags and --select are not yet supported because new code is needed to ensure exactly one VG matches before the VG starts to be processed.
2015-02-13 17:58:51 +03:00
Update vgextend to use process_each_vg.
pvchange: Use process_each_pv. Invalid devices no longer included in the counters printed at the end. May now need to use --ignoreskippedcluster if relying upon exit status. If more than one change is requested per-PV, attempt to perform them all. Note that different arguments still handle exit status differently.
2015-02-12 19:37:47 +03:00
Add --ignoreskippedcluster to pvchange.
Allow pvchange to modify several properties at once.
Update pvchange to use process_each_pv.
toollib: process_each_pv: use cmd->full_filter, not cmd->filter if we're getting full list of PV-capable devices (not just PVs) When lvmetad is used and at the same time we're getting list of all PV-capable devices, we can't use cmd->filter (which is used to filter out lvmetad responses - so we're sure that the devices are PVs already). To get the list of PV-capable devices, we're bypassing lvmetad (since lvmetad only caches PVs, not all the other devices which are not PVs). For this reason, we have to use the "full_filter" filter chain (just like we do when we're running without lvmetad). Example scenario: - sdo and sdp components of MD device md0 - sdq, sdr and sds components of mpatha multipath device - mpatha multipath device partitioned - vda device partitioned => sdo,sdp,sdr,sds, mpatha and vda should be filtered! $ lsblk -o NAME,TYPE NAME TYPE sdn disk sdo disk `-md0 raid0 sdp disk `-md0 raid0 sdq disk `-mpatha mpath `-mpatha1 part sdr disk `-mpatha mpath `-mpatha1 part sds disk `-mpatha mpath `-mpatha1 part vda disk |-vda1 part `-vda2 part |-fedora-swap lvm `-fedora-root lvm Before this patch: ================== use_lvmetad=0 (correct behaviour!) $ pvs -a PV VG Fmt Attr PSize PFree /dev/fedora/root --- 0 0 /dev/fedora/swap --- 0 0 /dev/mapper/mpatha1 --- 0 0 /dev/md0 --- 0 0 /dev/sdn --- 0 0 /dev/vda1 --- 0 0 /dev/vda2 fedora lvm2 a-- 9.51g 0 use_lvmetad=1 (incorrect behaviour - sdo,sdp,sdq,sdr,sds and mpatha not filtered!) $ pvs -a PV VG Fmt Attr PSize PFree /dev/fedora/root --- 0 0 /dev/fedora/swap --- 0 0 /dev/mapper/mpatha --- 0 0 /dev/mapper/mpatha1 --- 0 0 /dev/md0 --- 0 0 /dev/sdn --- 0 0 /dev/sdo --- 0 0 /dev/sdp --- 0 0 /dev/sdq --- 0 0 /dev/sdr --- 0 0 /dev/sds --- 0 0 /dev/vda --- 0 0 /dev/vda1 --- 0 0 /dev/vda2 fedora lvm2 a-- 9.51g 0 With this patch applied: ======================== use_lvmetad=1 $ pvs -a PV VG Fmt Attr PSize PFree /dev/fedora/root --- 0 0 /dev/fedora/swap --- 0 0 /dev/mapper/mpatha1 --- 0 0 /dev/md0 --- 0 0 /dev/sdn --- 0 0 /dev/vda1 --- 0 0 /dev/vda2 fedora lvm2 a-- 9.51g 0
2015-02-12 15:36:05 +03:00
Fix pvs -a used with lvmetad to filter out devices unsuitable for PVs.
report: define ba_start, vg_free and seg_start fields as DM_REPORT_FIELD_TYPE_SIZE instead of DM_REPORT_FIELD_TYPE_NUM This makes a difference when using selection criteria based on these fields - if those fields are defined as DM_REPORT_FIELD_TYPE_SIZE (in contrast to DM_REPORT_FIELD_TYPE_NUMBER), units are also recognize in selection clause. For example: $ lvs -o+seg_start vg1/lv2 LV VG Attr LSize Start lv2 vg1 -wi-a----- 12.00m 0 lv2 vg1 -wi-a----- 12.00m 8.00m Before this patch: $ lvs -o+seg_start --select 'seg_start=8m' Found size unit specifier but numeric value expected for selection field seg_start. Selection syntax error at 'seg_start=8m'. Use 'help' for selection to get more help. With this patch applied: $lvs -o+seg_start --select 'seg_start=8m' LV VG Attr LSize Start lv2 vg1 -wi-a----- 12.00m 8.00m (the same applies for ba_start and vg_free fields)
2015-02-11 15:57:18 +03:00
Fix selection to recognize units for ba_start, vg_free and seg_start fields.
tools: allow -S|--select for vgexport and vgimport
2014-12-12 14:03:34 +03:00
Add support for -S/--select to vgexport and vgimport.
tools: allow -S|--select for vgdisplay, lvdisplay and pvdisplay without -C We already allowed -S|--select with {vg,lv,pv}display -C (which was then equal to {vg,lv,pv}s command. Since we support selection in toolib now, we can support -S also without using -C in *display commands now.
2014-12-12 12:20:15 +03:00
Add support for -S/--select to vgdisplay, lvdisplay and pvdisplay without -C.
tools: allow -S|--select for vgremove and lvremove
2014-12-12 11:34:50 +03:00
Add support for -S/--select to vgremove and lvremove.
tools: allow -S|--select for vgchange, lvchange and pvchange
2014-12-03 12:03:48 +03:00
Add support for -S/--select to vgchange,lvchange and pvchange.
report: implement report_for_selection We have 3 input report types: - LVS (representing "_select_match_lv") - VGS (representing "_select_match_vg") - PVS (representing "_select_match_pv") The input report type is saved in struct selection_handle's "orig_report_type" variable. However, users can use any combination of fields of different report types in selection criteria - the resulting report type can thus differ. The struct selection_handle's "report_type" variable stores this resulting report type. The resulting report_type can end up as one of: - LVS - VGS - PVS - SEGS - PVSEGS This patch adds logic to report_for_selection based on (sensible) combination of orig_report_type and report_type and calls appropriate reporting functions or iterates over multiple items that need reporting to determine the selection result.
2014-12-01 17:40:03 +03:00
Add infrastructure to support selection for non-reporting tools.
lvm: recognize LVM_COMMAND_PROFILE env var for default command profile to use in LVM commands Once LVM_COMMAND_PROFILE environment variable is specified, the profile referenced is used just like it was specified using "<lvm command> --commandprofile". If both --commandprofile cmd line option and LVM_COMMAND_PROFILE env var is used, the --commandprofile cmd line option gets preference.
2015-02-09 16:16:24 +03:00
Add LVM_COMMAND_PROFILE env var to set default command profile name to use.

Deactivate unused thin pools activated with lvm2 pre-2.02.112 versions.
raid: check lock holding LV Since raid could be used as stacked LV - check lock holding LV for proper locking type for clustered usage.

pre-release
2015-01-30 19:16:51 +03:00
Support udev external dev info for filters: PV min size, mpath, md, partition.
WHATS_NEW
2015-01-30 15:29:51 +03:00
Add fw_raid_component_detection lvm.conf option to enable FW raid detection.
Add devices/external_device_info_source lvm.conf option ("none" by default).
lv_manip: add for_each_sub_lv_except_pools() for_each_sub_lv() now scans in depth also pools, however for rename we actually do want to skip pools. So add a new for_each_sub_lv_except_pools() to be used by rename, every other user of for_each_sub_lv() scans every sub LV with pools included. This is i.e. necessary for properly working preload of pools that are using raid arrays.
2015-01-30 14:27:49 +03:00
Scan pools in for_each_sub_lv() and add for_each_sub_lv_except_pools().
WHATS_NEW: previous commit
2015-01-30 13:28:10 +03:00
Fix lvm2app lvm_lv_get_property return value for fields with info/status ioctl.
lvm2app: fix lvm_lv_get_attr regression causing unknown values This is a regression from v115 where some of the fields/properties were converted to using the common "struct lvinfo" and "struct lv_seg_status" so we don't need to issue info and status ioctl several times per one reported line. Not all fields are converted yet, but one that *is* converted is the lv_attr field with the lv_attr_dup counterpart used in lvm_lv_get_attr lvm2app fn. These changes were introduced with e34b004422f0d51263e0d34f4064556cfc9148f6 and later - this patch introduced the "info_ok" field in the lv_with_info_and_seg_status structure which encapsulates the lvinfo and lv_seg_status struct. For the lv_attr_dup, the lv_attr_dup code missed the assignment for the "info_ok" flag which saves the result of the lv_info_with_seg_status call. Hence such info was marked as unusable - unknown and it was returned as such via lvm_lv_get_attr lvm2app fn.
2015-01-30 11:45:22 +03:00
Fix lvm2app regression in lvm_lv_get_attr causing unknown values (2.02.115).
cache: use writethrough cache_mode for older metadata When cache_mode is undefined, the read of metadata will miss to set a bit with mode and fails to process metadata on internal error: Internal error: LV vg/lvol1 has uknown feature flags 0. Fix it by setting it to writethrough mode.
2015-01-29 14:05:58 +03:00
Set default cache_mode to writehrough when missing in metadata.
thin: preserve chunksize with lvconvert When repairing thin pool or swapping thin pool metadata, preserve chunk_size property and avoid to be automatically changed later in the code to better match thin pool metadata size.
2015-01-28 17:12:38 +03:00
Preserve chunk size with repair and metadata swap of a thin pool.
raid: fix raid image splitting When raid leg is extracted, now the preload code handles this state correctly and put proper new table entry into dm tree, so the activation of extracted leg and removed metadata works after commit.
2015-01-28 15:39:41 +03:00
Fix raid --splitmirror 1 functionality (2.02.112).
raid: fix tree preload for splitting raid images When raid is being splitted, extracted leg & metadata is still floating in the table - and thus we need to detect this case and properly preload their matching table so consequent activation of extracted LVs properly renames (and FREES) existing raid images, so ongoing image name shifting will work.
2015-01-28 15:36:25 +03:00
Fix tree preload to handle splitting raid images.
devices: Do not support unpartitioned DASD.
2015-01-23 23:01:34 +03:00
Do not support unpartitioned DASD devices.
config: improve config validation to check if setting with string value can be empty. For example, with dmeventd/executable set to "" which is not allowed for this setting, the config validation now ends up with: $ lvm dumpconfig --validate Configuration setting "dmeventd/executable" invalid. It cannot be set to an empty value. LVM configuration invalid. This check for empty values for string config settings was not done before (we only checked empty arrays, but not scalar strings).
2015-01-21 18:44:02 +03:00
Improve config validation to check if setting with string value can be empty.

Add support for lvcreate --errorwhenfull y|n for thin pools.
raid_manip: fix multi-segment misallocation on 'lvconvert --repair' An 'lvconvert --repair $RAID_LV" to replace a failed leg of a multi-segment RAID10/4/5/6 logical volume can lead to allocation of (parts of) the replacement image component pair on the physical volume of another image component (e.g. image 0 allocated on the same PV as image 1 silently impeding resilience). Patch fixes this severe resilince issue by prohibiting allocation on PVs already holding other legs of the RAID set. It allows to allocate free space on any operational PV already holding parts of the image component pair.
2015-01-14 15:41:55 +03:00
Fix lvconvert --repair to honour resilience requirement for segmented RAID LV.
dev-type: filter out partitioned device-mapper devices as unsuitable for use as PVs Normally, if there are partitions defined on top of device-mapper device, there should be a device-mapper device created for each partiton on top of the old one and once the underlying DM device is used by another devices (partition mappings in this case), it can't be used as a PV anymore. However, sometimes, it may happen the partition mappings are missing - either the partitioning tool is not creating them if it does not contain full support for device-mapper devices or the mappings were removed. Better safe than sorry - check for partition header on DM devs and filter them out as unsuitable for PVs in case the check is positive. Whatever the user is doing, let's do our best to prevent unwanted corruption (...by running pvcreate on top of such device that would corrupt the partition header).
2015-01-12 16:02:57 +03:00
Filter out partitioned device-mapper devices as unsuitable for use as PVs.
pvscan: notify lvmetad about device that is gone and pvscan is run with device path instead of major:minor pair If pvscan is run with device path instead of major:minor pair and this device still exists in the system and the device is not visible anymore (due to a filter that is applied), notify lvmetad properly about this. This makes it more consistent with respect to existing pvscan with major:minor which already notifies lvmetad about device that is gone due to filters. However, if the device is not in the system anymore, we're not able to translate the original device path into major:minor pair which lvmetad needs for its action (lvmetad_pv_gone fn). So in this case, we still need to use major:minor pair only, not device path. But at least make "pvscan --cache DevicePath" as near as possible to "pvscan --cahce <major>:<minor>" functionality. Also add a note to pvscan man page about this difference when using pvscan --cache with DevicePath and major:minor pair.
2015-01-12 15:50:11 +03:00
Also notify lvmetad about filtered device if using pvscan --cache DevicePath.
scripts: clvmd: replace awk functionality with LVM's selection No need to use awk now to get appropriate VGs/LVs, use LVM's own --select - it's quicker, it removes a need for external dependency on awk and it's also more readable.
2015-01-09 18:34:16 +03:00
Use LVM's own selection instead of awk expressions in clvmd startup scripts.
WHATS_NEW: line for previous commit

Introduce pvremove_many to avoid excessive metadata re-reading and messages.
cmirror: check for cmirror availability during cluster mirror creation and activation When creating/activating clustered mirrors, we should have cmirrord available and running. If it's not, we ended up with rather cryptic errors like: $ lvcreate -l1 -m1 --type mirror vg Error locking on node 1: device-mapper: reload ioctl on failed: Invalid argument Failed to activate new LV. $ vgchange -ay vg Error locking on node node 1: device-mapper: reload ioctl on failed: Invalid argument This patch adds check for cmirror availability and it errors out properly, also giving a more precise error messge so users are able to identify the source of the problem easily: $ lvcreate -l1 -m1 --type mirror vg Shared cluster mirrors are not available. $ vgchange -ay vg Error locking on node 1: Shared cluster mirrors are not available. Exclusively activated cluster mirror LVs are OK even without cmirrord: $ vgchange -aey vg 1 logical volume(s) in volume group "vg" now active
2015-01-05 18:45:30 +03:00
Check for cmirror availability during cluster mirror creation and activation.

2014-12-11 17:16:04 +03:00
Add missing recognition for --binary option with {pv,vg,lv}display -C.
vgimportclone: also notify lvmetad about changes if it's used All the LVM commands are run in mode without lvmetad use (since lvmetad can't handle duplicates). When we're finished with vgimportclone, we need to notify lvmetad about changes.

2014-12-10 15:43:54 +03:00
Fix vgimportclone to notify lvmetad about changes done if lvmetad is used.
vgimportclone: replace awk with dumpconfig to generate temporary lvm.conf for vgimportclone With current dumpconfig, we can generate lvm.conf easily - we can merge current lvm.conf with the config given on cmd line: lvm dumpconfig --mergedconfig --config "..." This is a bit simpler than using awk and it also avoids problems when some of the configuration is missing in existing lvm.conf file and hardcoded defaults are used instead. The dumpconfig handles this transparently.
2014-12-10 15:25:23 +03:00
Fix vgimportclone to properly override config if it is missing in lvm.conf.
configure: fix automatic use of configure --enable-udev-systemd-background-jobs Fix incorrect test in configure which sets --enable-udev-systemd-background-jobs automatically if proper systemd version is available. The UDEV_SYSTEMD_BACKGROUND_JOBS variable was not properly set to "yes" in case systemd is available and we had "maybe" for this variable before.
2014-12-08 12:51:33 +03:00
Fix automatic use of configure --enable-udev-systemd-background-jobs.
raid: properly rename split image When we split leg from raid - we take a proper new lock for a new LV. However for now activation checks only 'existince' of device UUID, but it's not validating device has a proper name. As a quick fix call suspend()/resume() to rename after split mirror.
2014-12-04 16:24:44 +03:00
Correctly rename active split LV with -splitmirrors for raid1.

2014-11-26 19:09:47 +03:00
Fix regression when parsing /dev/mapper dir (2.02.112).
thin: add missing 64KB rounding When chunk size needs to be estimated, the code missed to round to proper 64kb boundaries (or power of 2 for older thin pool driver). So for some data and metadata size (i.e. 10GB and 4MB) it resulted in incorrect chunk size (not being a multiple of 64KB) Fix it by adding proper rounding and also use 1 routine for 2 places where the same calculation is made. Fix also incorrect printed warning that has used 'ffs()' (which returns first 'least significant' bit in word) and it was not really giving any useful size info and replace it with properly estimated chunk size.
2014-11-26 11:27:40 +03:00

2014-11-21 21:36:51 +03:00
Fix regression in vgscan --mknodes usage (2.02.112).
configure: fix CLVMD_PATH location Commit d2c116058e72d365802eb5641be60a615daacb96 introduced regression with CLVMD_PATH. + CLVMD_PATH="$clvmd_prefix/sbin/clvmd" test "$prefix" != NONE && clvmd_prefix=$prefix It has set CLVMD_PATH before clvmd_prefix got its final value. Move it one line below.
2014-11-21 18:33:48 +03:00
Respect --prefix when setting CLMVD_PATH configure (2.02.89).
configure: make configure --enable-udev-systemd-background-jobs only for systemd >= 205 systemd-run is available in systemd>=205. Also, this fix prevents systemd-specific udev rules in 69-dm-lvm-metad.rules to appear in case systemd environment is not available - make configure to check this automatically and use these systemd specific rules only if it is applicable.
2014-11-19 15:47:09 +03:00
Default to configure --enable-udev-systemd-background-jobs for systemd>=205.
toolib: fix ignore_vg Rework ignore_vg() API so it properly handles multiple kind of vg_read_error() states. Skip processing only otherwise valid VG. Always return ECMD_FAILED when break is detected. Check sigint_caught() in front of dm iterator loop. Add stack for _process failing ret codes.
2014-11-14 12:50:31 +03:00
Fix ignore_vg() to properly react on various vg_read errors (2.02.112).
vg_read: use new error flag Failed recovery provides different (NULL) VG then FAILED_INCONSISTENT. Mark it with different failure bit - since FAILED_INCONSISTENT is supposed to contain something 'usable' (thought inconsistent).
2014-11-14 16:55:57 +03:00
Failed recovery returns FAILED_RECOVERY status flag for vg_read().
pvck: Use non-zero exit status after failure.
2014-11-13 15:26:43 +03:00

Add _corig as reserved suffix.
pre-release
2014-11-11 17:13:00 +03:00
Reduce number of VG writes and commits when creating spare volumes.
lv_manip: remove_layer_from_lv restore lv name Since we 'layer' for cache origin which and we support dropping cache layer - we need to restore origin name in case the origin LV is more complex target - i.e. raid. Drop _corig from name Cleanup and rename parent -> parent_lv.
2014-11-09 21:48:39 +03:00
When remove_layer_from_lv() removes layer, restore subLV names.
cache: used cache-pool becomes invisible While cache-pool is in use - it is considered invisible.
2014-11-09 23:04:33 +03:00
Cache-pool in use becomes invisible LV.
pools: prompt only when metadata lv exists If the VG has no pool metadata volume, don't prompt about removal of _pmspare.
2014-11-08 15:53:13 +03:00
Don't prompt for removal of _pmspare in VG without pool metadata LV.
activate: check all snap segs are inactive When deactivating origin, we may have possibly left table in broken state, where origin is not active, but snapshot volume is still present. Let's ensure deactivation of origin detects also all associated snapshots are inactive - otherwise do not skip deactivation. (so i.e. 'vgchange -an' would detect errors)
2014-11-05 13:53:11 +03:00
Deactivation of snapshot origin detects and deactivates left-over snapshots.
snapshot: no snapshot of any cache type LVs Unsupported as of now.
2014-11-05 01:21:07 +03:00
Properly report error when taking snapshot of any cache type LV.
dmeventd: Add basic thread debugging messages. Only with -DDEBUG.
2014-11-04 21:56:20 +03:00
Add basic thread debugging messages to dmeventd.
dmeventd: Include shutdown threads in responses. When responding to DM_EVENT_CMD_GET_REGISTERED_DEVICE no longer ignore threads that have already been unregistered but which are still present. This means the caller can unregister a device and poll dmeventd to ensure the monitoring thread has gone away before removing the device. If a device was registered and unregistered in quick succession and then removed, WAITEVENT could run in parallel with the REMOVE. Threads are moved to the _thread_registry_unused list when they are unregistered.
2014-11-04 19:58:14 +03:00
Include threads being shutdown in dmeventd device registration responses.
thin: check for new pool before creating thin volume Call check_new_thin_pool() to detect in-use thin-pool. Save extra reactivation of thin-pool when thin pool is not active. (it's now a bit more expensive to invoke thin_check for new pools.) For new pools: We now active locally exclusively thin-pool as 'public' LV. Validate transaction_id is till 0. Deactive. Prepare create message for thin-pool and exclusively active pool. Active new thin LV. And deactivate thin pool if it used to be inactive.
2014-11-04 17:08:15 +03:00
Inital support for external users of thin pools based on transaction_id.
cache: report stats for cache volumes usage Show some stats with 'lvs' Display same info for active cache volume and cache-pool. data% - #used cache blocks/#total cache blocks meta% - #used metadata blocks/#total metadata blocks copy% - #dirty/#used cache blocks TODO: maybe there is a better mapping - should be seen as first-try-and-see.
2014-11-03 14:38:29 +03:00
Report some basic percentage info for cache pools.
lvmcmdline: support size_mb_arg_with_percent New size_mb_arg_with_percent is able to read size_mb_arg but also it's able to read % values. Percent parsing is share with int_arg_with_sign_and_percent.
2014-10-30 16:52:37 +03:00
Introduce size_mb_arg_with_percent() for advanced size arg reading.
lvmcmdline: extra support for decimal point If root has locales with different decimal point then '.' (i.e. Czech with ',') lets be tolerant and retry with "C" locales in the case '.' is found during parse of number. Locales are then restored back.
2014-10-28 13:20:33 +03:00
Add extra support for '.' as decimal point in size args.
pre-release
2014-11-11 17:13:00 +03:00
Add configure parameters for default segment type choices.
Add global/sparse_segtype_default setting to use thin for --type sparse.
man: lvconvert/create updates More description for cache support. Introduce --pooldatasize option.
2014-10-07 16:48:38 +04:00
Update and correct lvcreate and lvcovert man pages.
segments: mark more of them unzeroable Use segment flags to avoid zeroing of cache, cache pool snapshot and thin pool segments. We never want to zero these segment types. Note: Snapshot COW and Cache origin are created as stripes thus are then properly zeroed.
2014-10-20 16:57:24 +04:00
Mark pools and snapshots as unzeroable volumes.
lvcreate: check for conflicting -Zy -Wy Let the finaly state of zero & wipe_signature to be resolved later together with all the types. Don't play with zero assigment and segtype flag (i.e. thin-pool -Z has different meaning). Check if the passed options do allow requested zeroing/wiping. lvcreate without -Z or -W will fallback to warning if the device cannot be zeroed, however if user requested them explicitely it will give user error.
2014-10-21 22:50:26 +04:00
Check for zeroing of volume after segment type is fully detected.
toollib: persistent major minor Deduce -M from presence of --minor, --major option if not specified on command line.
2014-10-23 16:26:16 +04:00
Better support for persistent major and minor options with lvcreate.
lvcreate: new validation code Refactor lvcreate code. Prefer to use arg_outside_list_is_set() so we get automatic 'white-list' validation of supported options with different segment types. Drop used lp->cache, lp->cache and use seg_is_cache(), seg_is_thin() Draw clear border where is the last moment we could change create segment type. When segment type is given with --type - do not allow it to be changed later. Put together tests related to individual segment types. Finish cache conversion at proper part of lv_manip code after the vg_metadata are written - so we could correcly clean-up created stripe LV for cache volume.
2014-10-24 17:26:41 +04:00
Refactor lvcreate towards more complete validation of all supported options.
lvcreate: handle linear segment Put in code to accept 'linear' segment type (when specified stripes cannot be used) Also report 'error' when unknown type is specified.
2014-10-11 20:36:40 +04:00
Support lvcreate --type linear.
lv_manip: improve should_wipe reporting We want to print smarter warning message only when the zeroing was not provided on the first zeroable segment of newly created LV. Put warning within _should_wipe_lv function to avoid reevaluation of same conditions twice.
2014-10-22 15:29:25 +04:00
Improve _should_wipe_lv() to warn with message.
lvcreate: better logging for temporary device Hide creation of temporary LVs and print them only in verbose mode. e.g. hides confusing message about creation of _pmspare device during creation of pool.
2014-10-20 23:53:48 +04:00
Inform about temporarily created volumes only in verbose mode.
pool: fix testmode support with pools Allow the --test mode to proceed further.
2014-10-20 17:03:24 +04:00
Better support for --test mode with pool creation.
raid: query lock holder Ask for lock the proper LV. Use the top-most LV to query for locally exclusive lock. The rest of operations are then using 'lv_info()' TODO: Check all devices are reloaded from proper level. In general any query on lv_is_active is supposed to be running ona lv_lock_holder() volume.
2014-10-21 12:53:56 +04:00
Query lock holding LV when replacing and converting raid volumes.
cache: validate for locked Add extra safety.
2014-10-20 16:58:29 +04:00
Add extra validate for locked lv within validate_lv_cache_create().
segments: introduce lvseg_name Instead of segtype->ops->name() introduce lvseg_name(). This also allows us to leave name() function 'empty' for default return of segtype->name. TODO: add functions for rest of ops->
2014-10-20 20:40:39 +04:00
Add internal lvseg_name() function.
pre-release
2014-11-11 17:13:00 +03:00
Skip use of lock files for virtual internal VG names.
report: fix selection on {vg,lv}_permissions fields to properly match selection criteria There was a bug in value and their synonym definition for these two fields causing selections on these fields to not work correctly - nothing matched against vg/lv_permissions fields even if selection criteria should have matched. Scenario: $ lvs -o name,lv_permissions vg LV LPerms lvol0 read-only lvol1 writeable Before this patch: $ lvs -o name,lv_permissions vg -S 'permissions=read-only' (blank) $ lvs -o name,lv_permissions vg -S 'permissions=writeable (blank) With this patch applied: $ lvs -o name,lv_permissions vg -S 'permissions=read-only' LV LPerms lvol0 read-only $ lvs -o name,lv_permissions vg -S 'permissions=writeable' LV LPerms lvol1 writeable Also synonyms match correctly now: $ lvs -o name,lv_permissions vg -S 'permissions=rw' LV LPerms lvol1 writeable
2014-10-23 17:03:04 +04:00
Fix selection on {vg,lv}_permissions fields to properly match selection criteria.
report: lv_permissions: display read-only/read-only-override instead of blank when LV is not writeable Before this patch: $ lvs -o name,lv_attr,lv_permissions LV Attr LPerms root -wi-ao---- writeable swap -wi-ao---- writeable lvol0 -Ri-a----- lvol1 -ri-a----- lvol2 -wi-a----- writeable lvol3 -ri------- With this patch applied: $ lvs -o name,lv_attr,lv_permissions LV Attr LPerms root -wi-ao---- writeable swap -wi-ao---- writeable lvol0 -Ri-a----- read-only-override lvol1 -ri-a----- read-only lvol2 -wi-a----- writeable lvol3 -ri------- read-only ("read-only-override" is displayed if the "writeable" permission is overriden based on "activation/read_only_volume_list" lvm.conf setting)
2014-10-23 12:18:29 +04:00
Fix lv_permissions reporting to display read-only{-override} instead of blank.
liblvm2cmd: recognize quotes properly when splitting cmd line string into argv array fields Fix lvm_split that is called when cmd line string is separated into argv fields to recognize quote chars ('\'" and '"') properly and when these quotes are used, consider the text within quotes as one argument, do not separate it based on space characters inside. The lvm_split is used during processing lvm shell command line or when calling lvm commands through cmdlib (e.g. dmeventd plugins). For example, the lvm shell scenario: Before this patch: $lvm lvm> lvs --config 'global{ suffix=0 }' Parse error at byte 9 (line 1): unexpected token Failed to set overridden configuration entries. With this patch applied: $lvm lvm> lvs --config 'global{ suffix=0 }' LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert root fedora -wi-ao---- 9.00g swap fedora -wi-ao---- 512.00m (Exactly the same problem is hit when calling LVM commands with quoted arguments via lvm2cmd lib in dmeventd plugins.)
2014-10-17 15:55:06 +04:00
Fix liblvm2cmd and lvm shell to respect quotes around args in cmd line string.
vgcreate: Permit non-power-of-2 extent sizes. Relax validation to permit extent sizes > 128KB that are not powers of 2 with lvm2 format. Existing code was already capable of handling this.
2014-10-14 21:12:15 +04:00
Permit extent sizes > 128KB that are not power of 2 with lvm2 format.
systemd: remove workaround for lvm2-monitor.service's ExecStop line Bug https://bugzilla.redhat.com/show_bug.cgi?id=843587 is handled better now - the hang does not occur anymore. There are still error messages issued though during shutdown if someone stops lvm2-lvmetad.service manually that lvm2-monitor.service depends on (even during shutdown). These errors are correct though and will point to incorrect configuration (still having use_lvmetad=1 in lvm.conf and stopping lvm2-lvmetad.service manually). The workaround to prevent the hang is not needed now. So the '--config "global{use_lvmetad=0}"' is now removed from the lvm2-monitor.service's ExecStop line.
2014-10-14 11:56:58 +04:00
Remove workaround for lvm2-monitor.service hang on stop if lvmetad stopped.
vgremove: Use process_each_lv_in_vg.
2014-10-07 19:45:45 +04:00
Change vgremove to use process_each_lv_in_vg.
pre-release
2014-11-11 17:13:00 +03:00
Allow lvconvert --repair and --splitmirrors on internal LVs.
test: Add process-each toollib tests.
2014-10-07 04:08:03 +04:00
Introduce WARN_ flags to control some metadata warning messages.
Use process_each_pv in vgreduce.
Refactor process_each_pv in toollib.
pool: validate_pool_chunk_size Introduce pool function for validation of chunk size. It's good idea to be able to reject invalid chunk size when entered on command line before we open VG.
2014-10-06 14:18:57 +04:00
Introduce single validation routine for pool chunk size.
vg/lvremove: support --yes Make --yes equivalent to DONT_PROMT (--force). So user could use 'lvremove --yes vg/lvol1' skipping prompt.
2014-10-04 19:05:29 +04:00
Support --yes like --force in vg/lvremove to skip y|n prompt.
lvconvert: splitsnapshot supports --yes Handle --yes arg to skip prompt.
2014-10-06 16:42:47 +04:00
Support --yes with lvconvert --splitsnapshot.
lvconvert more test for thin external origin Some LV types were not properly disallowed to be used as external origin.
2014-10-06 15:15:31 +04:00
Fix detection of unsupported thin external lvconversions.
lvconvert: cache and thin conversion validation More test for supported conversion.
2014-10-06 15:44:59 +04:00
Fix detection of unsupported cache and thin pool lvconversions.
lvconvert: validate cache conversion to snapshot Cache cannot be converted into snapshot cow nor origin.
2014-10-06 14:27:35 +04:00
Fix detection of unsupported lvconversion of cache to snapshot.
cache: improve creation code Move code to better locations. Improve test and remove invalid ones (i.e. no reason to require cache size to be >= then origin). Correctly comment where the code is doing actual conversion of other existing volume - we do already a similar thing with external origins. Lots of new command line options and combinations is now supported. Hopefully older syntax still works as well. lvcreate --cache --cachepool vg/pool -l1 lvcreate --type cache --cachepool vg/pool -l1 lvcreate --type cache-pool vg/pool -l1 lvcreate --type cache-pool --name pool vg -l1 ... and many many more ...
2014-10-04 01:51:54 +04:00
Improve code for creation of cache and cache pool volumes.
lvremove: detect cluster wide active state If the LV is active remotely do not skip question for deactivation.
2014-10-04 01:49:57 +04:00
Check cluster-wide (not local) active status before removing LV.
cache: check activation of volume activated volume_list may silently skip activation which is then still reported as success.
2014-10-04 01:48:42 +04:00
Properly check if activation of removed cached LV really activated.
pre-release
2014-11-11 17:13:00 +03:00
lvremove cached LV removes cachepool (keep with lvconvert --splitcache).
pools: move removal of _pmspare Since _pmspare is internal volume move it to lv_remove_single - so it's automatically removed with last remove thin-pool. lv_remove_with_dependencies() is not always used for pool removal.
2014-10-04 01:34:16 +04:00
Always remove spare LV with last removed pool volume.
lvconvert: options splitcache, split, uncache --splitcache Splits only cached LV (also pool could be specified). Detaches cachepool from cached LV. --split Should be univerzal command to split various complex targets. At this moment it knows cache. --uncache Opposite command to --cache. Detaches and DELETES cachepool for cached LV. Note: we support thin pool cached metadata device for uncaching. Also use may specify wither cached LV or association cachepool device to request split of cache.
2014-10-04 17:32:24 +04:00
Support lvconvert --splitcache and --uncache of cached LV.
commands: support shortcut -H for cache objects Introduce cache_long_ARG for those instancies where --cache is not related to caching LV. (pvchange,vg|lv|pvscan). cache_ARG is now with -H shortcut.
2014-09-29 22:43:11 +04:00
Option --cache has also shortcut -H (i.e. lvcreate -H).
lvcreate: refactor code Over the time lvcreate code has accumulated various hacks. So try to move that code in right places. Detect all types early in _lvcreate_params() so functions like _read_size_params() do not need to change volume types. Also ultimately respect give volume --type, that its shortcut (-T, H, -m, -s) and after that options which do type estimation. (i.e. --cachepool, --thinpool) Avoid repeative tests - if we know all types are decode at once place we can 'optimize' number of validations.
2014-09-29 00:31:30 +04:00
Refactor lvcreate code and better preserve --type argument.
pre-release
2014-11-11 17:13:00 +03:00
Refactor filter processing around lvmetad.
test: Add process-each toollib tests.
2014-10-07 04:08:03 +04:00
Refactor process_each_lv in toollib.
toollib: Rewrite process_each_vg. Split VG argument collection from processing. This allows the two different loops through VGs to be replaced by a single loop. Replace unused struct cmd_vg and cmd_vg_read() replicator code with struct vg and vg_read() directly. [Committed by agk with cosmetic changes and tweaks.]
2014-10-03 23:47:19 +04:00
Refactor process_each_vg in toollib.
thin: no pool can be used for external origins Cache pool can't be external origin either. For simplicity use vg from passed LV.
2014-09-22 16:09:55 +04:00
Pools cannot be used as external origin.
snapshot: use lv_update_and_reload
2014-09-21 03:10:53 +04:00
Use lv_update_and_reload() for snapshot reload.
mirror: extend adjusted_mirror_region_size API We use adjusted_mirror_region_size() in two different contexts. Either on command line - here we do want to inform user about reduction of size. Or in pvmove activation context - here we should only use 'verbose' info.
2014-09-22 17:54:33 +04:00
Don't print message in adjusted_mirror_region_size() in activation.
lv_update_and_reload: use proper lock holder When requesting to reload an LV imrove this API to automatically reload its lock holding LV as in cluster only top-level LVs are addressable with lock.
2014-09-22 15:57:47 +04:00
Improve lv_update_and_reload() to find out proper lock holding LV.
lv_ondisk: option search for lv without vg_ondisk When vg_ondisk is NULL we do not need to search through the whole VG to find out the same LV. NOTE: as of now - VG locking is not enabled as some code parts are breaking memory locking rules (lvm2app). Once we enforce VG locking for read-only commands the effect will be much better for larger VGs.
2014-09-22 01:10:04 +04:00
Improve search of LV in lv_ondisk().
activate: lv_check_not_in_use no check of closed Don't perform expensive sysfs tests when the device is closed. (having open_count == 0).
2014-09-22 01:07:02 +04:00
Do not scan sysfs in lv_check_not_in_use() when device is closed.
lvchange: backup final metadata Shift backup after final metadata commit. Synchronize with wiping.
2014-09-19 17:16:26 +04:00
Backup final metadata after resync of mirror/raid.
tools: common handling of --persistent option Move common code for reading and processing of --persistent arguments for lvcreate and lvchange into lvmcmdline. Reuse validate_major_minor() routine for validation. Don't blindly activate LVs after change in cluster and instead only local reactivation is supported. (we have now many limited targets now). Dropping 'sigint_caught()' handling, since prompt() is resolving this case itself.
2014-09-19 16:57:02 +04:00
Unify handling of --persistent option for lvcreate and lvchange.
metadata: validate major, minor numbers Validate major, minor numbers after reading them from metadata.
2014-09-19 16:51:41 +04:00
Validate major and minor numbers stored in metadata.
WHATS_NEW
2014-09-18 20:19:16 +04:00
Use -fPIE when linking -pie executables.
pre-release
2014-11-11 17:13:00 +03:00
Support DEBUG_MEMLOCK to trap unsupported mmap usage.
cache: Enable cache segment type by default.
2014-09-18 02:13:15 +04:00
Enable cache segment type by default.
lvconvert: Restrict use of cache LVs. Refuse use of -m and -s with cache LVs until full support can be provided.
2014-09-17 19:41:58 +04:00
Ensure only supported volume types are used with cache segments.
cache-pool: Fix specification of cachemode when converting to cache-pool Failure to copy the 'feature_flags' lvconvert_param to the matching lv_segment field meant that when a user specified the cachemode argument, the request was not honored.
2014-09-17 07:19:53 +04:00
Fix inablility to specify cachemode when 'lvconvert'ing to cache-pool.
vgchange: support clustered conversion for active lv If we want to support conversion of VG to clustered type, we currently need to relock active LV to get proper DLM lock. So add extra loop after change of VG clustered attribute to exlusively activate all active top level LVs. When doing change -cy -> -cn we should validate LVs are not active on other cluster nodes - we could be sure about this only when with local exclusive activation - for other types we require user to deactivate volumes first. As a workaround for this limitation there is always locking_type = 0 which amongs other skip the detection of active LVs. FIXME: clvmd should handle looks for cluster locking type all the time.
2014-09-17 16:27:46 +04:00
Grab cluster lock for active LVs when setting clustered attribute.
va_list: properly pass va_list through functions Code should not just pass va_list arg through the function as args could be passed in many strange ways. Use va_copy(). For details look in i.e.: http://julipedia.meroh.net/2011/09/using-vacopy-to-safely-pass-ap.html
2014-09-15 17:33:56 +04:00
Use va_copy to properly pass va_list through functions.
devices: Detect rotational devices. Add dev_is_rotational() for future use by allocation code.
2014-09-16 03:44:25 +04:00
Add function to detect rotational devices.
mirrors: Fix checks for mirror/raid/pvmove LVs. Try to enforce consistent macro usage along these lines: lv_is_mirror - mirror that uses the original dm-raid1 implementation (segment type "mirror") lv_is_mirror_type - also includes internal mirror image and log LVs lv_is_raid - raid volume that uses the new dm-raid implementation (segment type "raid") lv_is_raid_type - also includes internal raid image / log / metadata LVs lv_is_mirrored - LV is mirrored using either kernel implementation (excludes non-mirror modes like raid5 etc.) lv_is_pvmove - internal pvmove volume
2014-09-16 03:13:46 +04:00
Review internal checks for mirror/raid/pvmove volumes.
Track mirror segment type with separate MIRROR flag.
Fix cmirror endian conversions.
cleanup: Use lv_is_ macros. Use lv_is_* macros throughout the code base, introducing lv_is_pvmove, lv_is_locked, lv_is_converting and lv_is_merging. lv_is_mirror_type no longer includes pvmove.
2014-09-16 00:33:53 +04:00
Introduce lv_is_pvmove/locked/converting/merging macros.
thin: check for active lv Before calling deactivate, check the lv is actually active, as we may reach this 'bad' error path with pool_lv inactive.
2014-09-15 15:42:43 +04:00
Avoid leaving linear logical volume when thin pool creation fails.
raid: destroy allocation handle on error path Don't leak ah memory pool on error path.
2014-09-12 13:37:01 +04:00
Don't leak alloc_handle on raid target error path.
raid: use _generate_raid_name Use new function to get implicit name validation (so we do not exit with internal error on metadata validation).
2014-09-12 13:39:48 +04:00
Properly validate raid leg names.
raid: add missing archive call Before starting to update raid metadata, archive existing unmodified one.
2014-09-12 13:30:38 +04:00
Archive metadata before starting their modification in raid target.
snapshot: add missing vg_revert Error path missed vg_revert call.
2014-09-21 03:10:06 +04:00
Add missing vg_revert() in suspend_lv() raid and snapshot error path.
raid: add missing backups Add backup() calls that were missing after successful update of metadata.
2014-09-11 21:05:40 +04:00
Add missing backup of lvm2 metadata after some raid modifications.
Use vg memory pool for extent allocation.
conf: add allocation/physical_extent_size config option for default PE size of VGs. Removes a need to use "vgcreate -s <desired PE size>" all the time time just to override hardcoded default which is 4096KiB.
2014-09-12 12:03:12 +04:00
Add allocation/physical_extent_size config option for default PE size of VGs.
pre-release
2014-11-11 17:13:00 +03:00
Demote an error to a warning when devices known to lvmetad are filtered out.
Re-order filter evaluation, making component filters global.
Fix logic that checks for full scan before iterating through devices.
Introduce common code to modify metadata and reload updated LV.
lv_rename: fix snapshot rename Fix rename operation for snapshot (cow) LV. Only the snapshot's origin has the lock and by mistake suspend and resume has been called for the snapshot LV. This further made volumes unusable in cluster. So instead of suspend and resuming list of LVs, we need to just suspend and resume origin. As the sequence write/suspend/commit/resume is widely used in lvm2 code base - move it to new lv_update_and_reload function.
2014-09-09 20:47:27 +04:00
Fix rename of active snapshot volume in cluster.
so: make sure shared libs are built with RELRO option In addition to using RELRO for daemons, use this option for shared libraries. See also commit a65ab773b4ddb06e87d678d3b2f4d0ca3e5b9fd0.

Version 2.02.110 - 26th August 2014
===================================
thin: fix volume_list support Fixing problem, when user sets volume_list and excludes thin pools from activation. In this case pool return 'success' for skipped activation. We need to really check the volume it is actually active to properly to remove queued pool messages. Otherwise the lvm2 and kernel metadata started to go async since lvm2 believed, messages were submitted. Add also better check for threshold when create a new thin volume. In this case we require local activation of thin pool so we are able to check pool fullness.
2014-08-26 14:10:29 +04:00
Fix manipulation with thin-pools which are excluded via volume_list.
thin: more forced ignoring of pool failure Support also 'vgremove -ff' to properly remove even inactive/broken thin pools. Update messages to use 'print_unless_silent' for the forced case.
2014-08-26 13:53:56 +04:00
Support lv/vgremove -ff to remove thin vols from broken/inactive thin pools.
configure: Fix shared lvm1 typo. via https://bugs.gentoo.org/520640
2014-08-23 02:42:55 +04:00
Fix typo breaking configure --with-lvm1=shared.
lvresize: Fix raid/mirror and %PE handling code. Sort out the lvresize calculation code to handle size changes specified as physical extents as well as logical extents and to process mirror resizing and raid extensions correctly. The 'approx alloc' option was masking the underlying problem.
2014-08-22 04:26:14 +04:00
Modify lvresize code to handle raid/mirrors and physical extents.
pre-release
2014-08-26 19:34:14 +04:00
Don't allow pvcreate to proceed if scanning or filtering fails.
RAID: Fail RAID4/5/6 creation if PE size is less than STRIPE_SIZE_MIN The maximum stripe size is equal to the volume group PE size. If that size falls below the STRIPE_SIZE_MIN, the creation of RAID 4/5/6 volumes becomes impossible. (The kernel will fail to load a RAID 4/5/6 mapping table with a stripe size less than STRIPE_SIZE_MIN.) So, we report an error if it is attempted. This is very rare because reducing the PE size down that far limits the size of the PV below that of modern devices.
2014-08-16 06:15:34 +04:00
Cleanly error when creating RAID with stripe size < PAGE_SIZE.
lvconvert: show name of activated volume Display the name of volume that needs to be activated for merging.
2014-08-14 13:12:02 +04:00
Print name of LV which on activation triggers delayed snapshot merge.
refactor: rename 'lv_type' field to 'lv_role' The 'lv_type' field name was a bit misleading. Better one is 'lv_role' since this fields describes what's the actual use of the LV currently - its 'role'.
2014-08-25 11:07:03 +04:00
Add lv_layout and lv_role LV reporting fields.
WHATS_NEW: previous commit
2014-08-15 15:31:11 +04:00
Properly display lvs lv_attr volume type and target type bit for cache origin.
pvcreate: Fix cache state with filters/sig wiping. _pvcreate_check() has two missing requirements: After refreshing filters there must be a rescan. (Otherwise the persistent filter may remain empty.) After wiping a signature, the filters must be refreshed. (A device that was previously excluded by the filter due to its signature might now need to be included.) If several devices are added at once, the repeated scanning isn't strictly needed, but we can address that later as part of the command processing restructuring (by grouping the devices). Replace the new pvcreate code added by commit 54685c20fc9dfb155a2e5bc9d8cf5f0aad944305 "filters: fix regression caused by commit e80884cd080cad7e10be4588e3493b9000649426" with this change to _pvcreate_check(). The filter refresh problem dates back to commit acb4b5e4de3c49d36fe756f6fb9997ec179b89c2 "Fix pvcreate device check."
2014-08-14 04:30:01 +04:00
Fix pvcreate_check() to update cache correctly after signature wiping.
filter-mpath: fix primary device lookup failure for partition when processing mpath filter If using persistent filter and we're refreshing filters (just like we do for pvcreate now after commit 54685c20fc9dfb155a2e5bc9d8cf5f0aad944305), we can't rely on getting the primary device of the partition from the cache as such device could be already filtered by persistent filter and we get a device cache lookup failure for such device. For example: $ lvm dumpconfig --type diff devices { obtain_device_list_from_udev=0 } $lsblk /dev/sda NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 128M 0 disk `-sda1 8:1 0 127M 0 part $cat /etc/lvm/cache/.cache | grep sda "/dev/sda1", $pvcreate /dev/sda1 dev_is_mpath: failed to get device for 8:1 Physical volume "/dev/sda1" successfully created The problematic part of the code called dev_cache_get_by_devt to get the device for the device number supplied. Then the code used dev_name(dev) to get the name which is then used in check whether there's any mpath on top of this dev... This patch uses sysfs to get the base name for the partition instead, hence avoiding the device cache which is a correct approach here.

Fix primary device lookup failure for partition when processing mpath filter.
activation: if LV inactive and non-clustered, do not issue "Cannot deactivate" on -aln The message "Cannot deactivate remotely exclusive device locally." makes sense only for clustered LV. If the LV is non-clustered, then it's always exclusive by definition and if it's already deactivated, this message pops up inappropriately as those two conditions are met. So issue the message only if the conditions are met AND we have clustered VG.
2014-08-07 18:44:09 +04:00
If LV inactive and non-clustered, do not issue "Cannot deactivate" on -aln.
pvmove: remove spurious "Skipping mirror LV" message on pvmove of clustered mirror With cmirrord, we can do pvmove of clustered mirror. The code checking suitability of LVs on the PV being moved issued a message if a mirror LV was found and the VG was clustered. However, the actual pvmove did work correctly. The top-level mirror LV is actually skipped in the code since it's always layered on top of internal LVs making up the mirror LV and for pvmove we consider these internal devices only as they're actually layered on top of concrete PVs then. But we don't need to issue any message here about skipping the top-level mirror LV - it's misleading here.
2014-08-07 17:23:58 +04:00
Remove spurious "Skipping mirror LV" message on pvmove of clustered mirror.

Version 2.02.109 - 5th August 2014
==================================
Remove lv_volume_type field from reports. (2.02.108)
Fix a segfault in lvscan --cache when devices were already missing. (2.02.108)
filters: fix regression caused by commit e80884cd080cad7e10be4588e3493b9000649426 Commit e80884cd080cad7e10be4588e3493b9000649426 tried to dump filters for them to be reevaluated when creating a PV to avoid overwriting any existing signature that may have been created after last scan/filtering. However, we need to call refresh_filters instead of persistent_filter->dump since dump requires proper rescannig to fill up the persistent filter again. However, this is true only for pvcreate but not for vgcreate with PV creation where the scanning happens before this PV creation and hence the next rescan (if not full scan), does not fill the persistent filter. Also, move refresh_filters so that it's called sooner and only for pvcreate, vgcreate already calls lvmcache_label_scan(cmd, 2) which then calls refresh_filters itself, so no need to reevaluate this again. This caused the persistent filter (/etc/lvm/cache/.cache file) to be wrong and contain only the PV just being processed with vgcreate <vg_name> <pv_name_to_create>. This regression caused other block devices to be filtered out in case the vgcreate with PV creation was used and then the persistent filter is used by any other LVM command afterwards.
2014-08-01 13:28:18 +04:00
Fix incorrect persistent .cache after vgcreate with PV creation. (2.02.108)
lvresize: Allow approximation with +%FREE. Make lvresize -l+%FREE support approximate allocation. Move existing "Reducing/Extending' message to verbose level and change it to say 'up to' if approximate allocation is being used. Replace it with a new message that gives the actual old and new size or says 'unchanged'.
2014-08-01 03:35:43 +04:00
Display actual size changed when resizing LV.
Allow approximate allocation with +%FREE in lvextend.
metadata: remove spurious "Physical volume <dev_name> not found" This is addendum to commit 2e82a070f3c9224da5c9f383d47e75a1715586cf which fixed these spurious messages that appeared after commit 651d5093edde3e0ebee9d75be1c9834efc152d91 ("avoid pv_read in find_pv_by_name"). There was one more "not found" message issued in case the device could not be found in device cache (commit 2e82a07 fixed this only for PV lookup itself). But if we "allow_unformatted" for find_pv_by_name, we should not issue this message even in case the device can't be found in dev cache as we just need to know whether there's a PV or not for the code to decide on next steps and we don't want to issue any messages if either device itself is not found or PV is not found. For example, when we were creating a new PV (and so allow_unformatted = 1) and the device had a signature on it which caused it to be filtered by device filter (e.g. MD signature if md filtering is enabled), or it was part of some other subsystem (e.g. multipath), this message was issued on find_pv_by_name call which was misleading. Also, remove misleading "stack" call in case find_pv_by_name returns NULL in pvcreate_check - any error state is reported later by pvcreate_check code so no need to "stack" here. There's one more and proper check to issue "not found" message if the device can't be found in device cache within pvcreate_check fn so this situation is still covered properly later in the code. Before this patch (/dev/sda contains MD signature and is therefore filtered): $ pvcreate /dev/sda Physical volume /dev/sda not found WARNING: linux_raid_member signature detected on /dev/sda at offset 4096. Wipe it? [y/n]: With this patch applied: $ pvcreate /dev/sda WARNING: linux_raid_member signature detected on /dev/sda at offset 4096. Wipe it? [y/n]: Non-existent devices are still caught properly: $ pvcreate /dev/sdx Device /dev/sdx not found (or ignored by filtering).
2014-07-31 11:30:25 +04:00
Remove possible spurious "not found" message on PV create before wiping.
activation: Fix upgrades using uuid suffixes. 2.02.106 added suffixes to some LV uuids in the kernel. If any of these LVs is activated with 2.02.105 or earlier, and then a later version is used, the LVs appear invisible and activation commands fail. The code now has to check the kernel for both old and new uuids.
2014-07-31 00:55:11 +04:00
Handle upgrade from 2.02.105 when an LV now gaining a uuid suffix is active.

Improve lvconvert --splitsnapshot validation.
WHATS_NEW: recent commits Commits: d169ff1e039ecdfb1efac0a6464ca149d71d8767 bccc2bef33af081264bbc356e37efe89ef78b796 f76879ba440aa93f2e237335fe2cca6951a636bf

Add report/list_item_separator lvm.conf option.
Add lv_active_{locally,remotely,exclusively} LV reporting fields.
Comment out devices/{preferred_names,filter} in default lvm.conf file.
lvconvert: update for thin a cache Major update of lvconvert code to handle cache and thin. related targets. Code tries to unify handling of cache and thin pools. Better supports lvm2 syntax: lvconvert --type cache --cachepool vg/pool vg/cache lvconvert --type thin --thinpool vg/pool vg/extorg lvconvert --type cache-pool vg/pool lvconvert --type thin-pool vg/pool as well as: lvconvert --cache --cachepool vg/pool vg/cache lvconvert --thin --thinpool vg/pool vg/extorg lvconvert --cachepool vg/pool lvconvert --thinpool vg/pool While catching much more command line errors. (Yet couple paths still needs more tests) Detects as much cmdline errors prior opening VG. Uses single lvconvert_name_params to convert LV names. Detects as much incompatibilies in VG prior prompting. Uses single prompt to confirm whole conversion. TODO: still the code needs fixes...
2014-07-11 14:15:23 +04:00
Enhance lvconvert thin, thinpool, cache and cachepool command line support.
display: show C only for cache and cachepool Keep target type (attr6) as the cache data and metadata volume has. (i.e. when will show 'raid' type if metadata is raid)
2014-07-08 00:26:56 +04:00
Display 'C' only for cache and cache-pool target types in lvs.
lvconvert: snapshot prompts to confirm conversion Since the type passed LV is changed and content of data detroyed, query user with prompt to confirm this operation. Also add a proper wiping of header. Using '--yes' will skip this prompt: lvconvert -s --yes vg/lv vg/lvcow
2014-07-08 00:33:31 +04:00
Prompt for confirmation before change LV into a snapshot exception store.
lvconvert: fix return codes Error codes in some function are directly used as command result - thus return 0 is not error code, but success - switch to proper ECMD_FAILED.
2014-07-11 14:24:32 +04:00
Return proper error codes for some failing lvconvert funtions.
cache: add tool support Introducing cache tool support.
2014-07-04 18:31:29 +04:00
Add initial code to use cache tools (cache_check|dump|repair|restore).
config: Adjust description of activation_mode.
2014-07-21 18:50:47 +04:00
Support lvdisplay --maps for raid.
Add --activationmode degraded to activate degraded raid volumes by default.
report: add lv_active_{locally,remotely,exclusively} LV reporting fields lv_active_{locally,remotely,exclusively} display the original "lv_active" field in a more separate way so that we can create selection criteria in a binary-based form (yes/no).
2014-07-09 16:28:50 +04:00
Add separate lv_active_{locally,remotely,exclusively} LV reporting fields.
WHATS_NEW: commits a473435..7021c8f1
2014-07-07 18:52:43 +04:00
Recognize "auto"/"unmanaged" values in selection for appropriate fields only.
Add report/binary_values_as_numeric lvm.conf option for binary values as 0/1.
Add --binary arg to pvs,vgs,lvs and {pv,vg,lv}display -C for 0/1 on reports.
Add separate reporting fields for each each {pv,vg,lv}_attr bit.
Separate LV device status reporting fields out of LV fields.
metadata: fix regression causing PVs not in VGs to be marked as allocatable If the PV is not yet in a VG, it's not allocatable. A regression introduced by commit 0283c439ec2dc195184a12f86a060b271476aae0 (_pv_create) and later commit a7ca10151795b4c4ed6fa4bf7d3d6b1a687430b0 (pv_read).
2014-07-07 15:58:42 +04:00
Fix regression causing PVs not in VGs to be marked as allocatable (2.02.59).
vgsplit: Fix VG component of lvid. Fix VG component of lvid in vgsplit and vgmerge Update vg_validate() to detect the error. Call lv_is_active() before moving LV into new VG, not after.
2014-07-03 22:06:04 +04:00
Fix VG component of lvid in vgsplit/vgmerge and check in vg_validate.
report: Add lv_parent field. Only defined for thin/cache/raid/mirror at this stage as it relies on get_only_segment_using_this_lv().
2014-07-04 02:49:34 +04:00
Add lv_full_name, lv_parent and lv_dm_path fields to reports.
report: Exclude hidden devices from lv_path field.
2014-07-02 17:57:00 +04:00
Change lv_path field to suppress devices that never appear in /dev/vg.
pool: delay conversion prompt First validate as much params as possible before prompting user about conversion to data and metadata LV.
2014-07-01 13:06:36 +04:00
Postpone thin pool lvconvert prompts (2.02.107).
thin: fix chunk_size conversion prompt skip Use --force only enables prompting for dangerous operation. User has to add --yes to skip this prompt.
2014-07-01 13:04:14 +04:00
Require --yes option to skip prompt to lvconvert thin pool chunksize.
lvremove: remove thin volumes on damaged pools Support remove of thin volumes With --force --force when thin pools is damaged. This way it's possible to remove thin pool with unrepairable metadata without requiring to manually edit lvm2 metadata. lvremove -ff vg/pool removes all thin volumes and pool even when thin pool cannot be activated (to accept removal of thin volumes in kernel metadata)
2014-07-02 02:13:32 +04:00
Support lvremove -ff to remove thin volumes from broken thin pools.
raid: don't skip prompt with force Yes is meant to be used to skip all new prompts. (--force just adds more prompts).
2014-07-01 11:55:04 +04:00
Require --yes to skip raid repair prompt.
make: Fix pofile and .d file generation. Use builddir not srcdir with make pofile. Append 'incfile:' lines to %.d files to handle newly-missing dependencies without 'make clean' after a file is moved or deleted.
2014-07-02 03:48:50 +04:00
Change makefile %.d generation to handle filename changes without make clean.
Fix use of buildir in make pofile.
uuid: add more private uuid sufixes Use suffixes for easier detection of private volumes. This commit makes older volume UUIDs incompatible and it most probably needs machine reboot after upgrade.
2014-06-27 02:03:31 +04:00
Enhance private volumes UUIDs with suffixed for easier detection.
thin: do not create reserved LVs When creating pool's metadata - create initial LV for clearing with some generic name and after the volume is create & cleared - rename it to reserved name '_tmeta/_cmeta'. We should not expose 'reserved' names for public LVs.
2014-06-30 13:33:23 +04:00
Do not use reserved _[tc]meta volumes for temporary LVs.
thin: repaired LV uses _meta%d Don't leave 'regular' LV with reserved suffix for a user. After succefull repair use 'normal' (non-reserved) LV name for backup of original metadata.
2014-06-30 13:01:04 +04:00
Leave backup pool metadata with _meta%d suffix instead of reserved _tmeta%d.
raid: Allow repair to reuse PVs from same image that suffered a PV failure When repairing RAID LVs that have multiple PVs per image, allow replacement images to be reallocated from the PVs that have not failed in the image if there is sufficient space. This allows for scenarios where a 2-way RAID1 is spread across 4 PVs, where each image lives on two PVs but doesn't use the entire space on any of them. If one PV fails and there is sufficient space on the remaining PV in the image, the image can be reallocated on just the remaining PV.
2014-06-26 07:26:06 +04:00
Allow RAID repair to reuse PVs from same image that suffered a failure.
raid/misc: Allow creation of parallel areas by LV vs segment I've changed build_parallel_areas_from_lv to take a new parameter that allows the caller to build parallel areas by LV vs by segment. Previously, the function created a list of parallel areas for each segment in the given LV. When it came time for allocation, the parallel areas were honored on a segment basis. This was problematic for RAID because any new RAID image must avoid being placed on any PVs used by other images in the RAID. For example, if we have a linear LV that has half its space on one PV and half on another, we do not want an up-convert to use either of those PVs. It should especially not wind up with the following, where the first portion of one LV is paired up with the second portion of the other: ------PV1------- ------PV2------- [ 2of2 image_1 ] [ 1of2 image_1 ] [ 1of2 image_0 ] [ 2of2 image_0 ] ---------------- ---------------- Previously, it was possible for this to happen. The change makes it so that the returned parallel areas list contains one "super" segment (seg_pvs) with a list of all the PVs from every actual segment in the given LV and covering the entire logical extent range. This change allows RAID conversions to function properly when there are existing images that contain multiple segments that span more than one PV.
2014-06-26 06:20:41 +04:00
New RAID images now avoid allocation on any PVs in the same parent RAID LV.
filters: always reevaluate filter before creating a PV ...to avoid using cached value (persistent filter) and therefore not noticing any change made after last scan/filtering - the state of the device may have changed, for example new signatures added. $ lvm dumpconfig --type diff allocation { use_blkid_wiping=0 } devices { obtain_device_list_from_udev=0 } $ cat /etc/lvm/cache/.cache | grep sda $ vgscan Reading all physical volumes. This may take a while... Found volume group "fedora" using metadata type lvm2 $ cat /etc/lvm/cache/.cache | grep sda "/dev/sda", $ parted /dev/sda mklabel gpt Information: You may need to update /etc/fstab. $ parted /dev/sda print Model: QEMU QEMU HARDDISK (scsi) Disk /dev/sda: 134MB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags $ cat /etc/lvm/cache/.cache | grep sda "/dev/sda", ==== Before this patch: $ pvcreate /dev/sda Physical volume "/dev/sda" successfully created With this patch applied: $ pvcreate /dev/sda Physical volume /dev/sda not found Device /dev/sda not found (or ignored by filtering).
2014-06-25 18:19:27 +04:00
Always reevaluate filters just before creating PV.

Version 2.02.107 - 23rd June 2014
=================================
locking: Introduce LCK_ACTIVATION. Take a local file lock to prevent concurrent activation/deactivation of LVs. Thin/cache types and an extension for cluster support are excluded for now. 'lvchange -ay $lv' and 'lvchange -an $lv' should no longer cause trouble if issued concurrently: the new lock should make sure they activate/deactivate $lv one-after-the-other, instead of overlapping. (If anyone wants to experiment with the cluster patch, please get in touch.)
2014-06-20 16:24:02 +04:00
Introduce LCK_ACTIVATION to avoid concurrent activation of basic LV types.
lvchange: better --refresh of raid and mirrors Use lv_check_not_in_use() to detect openned device. Plain info.open_count is not good enough for udev random device openning.
2014-06-19 13:58:28 +04:00
Fix open_count test for lvchange --refresh or mirrors and raids.
WHATS_NEW: commits 7dbbc05a69c4cb9756464720cad29e3c1ed971c3..b16f5633ab199dedfd25f08562f686a6fb4aba9d Report selection support...
2014-06-18 12:48:53 +04:00
Update pvs,vgs,lvs and lvm man page for selection support.
Add -S/--select to lvm devtypes for report selection.
Add -S/--select to pvs,vgs,lvs and {pv,vg,lv}display -C for report selection.
Use dm_report_init_with_selection now, implicit "selected" field appears.
Make use of libdm's DM_REPORT_FIELD_TYPE{SIZE,PERCENT,STRING_LIST} for fields.
pvmove: tidy
2014-06-19 16:40:47 +04:00
Support all-or-nothing pvmove --atomic.
snapshot: %ORIGIN is relative to data size Let's use the size of origin as the real base for percenta calculation, and 'silenly' add needed metadata space for snapshot. So now command 'lvcreate -s -l100%ORIGIN vg/lv' should always create a snapshot to handle full device overwrite.
2014-06-17 15:33:42 +04:00
Automatically add snapshot metadata size for -l %ORIGIN calculation.
cache: Properly rename origin LV tree when adding "_corig" When creating a cache LV with a RAID origin, we need to ensure that the sub-LVs of that origin properly change their names to include the "_corig" extention of the top-level LV. We do this by first performing a 'lv_rename_update' before making the call to 'insert_layer_for_lv'.
2014-06-17 03:15:39 +04:00
When converting RAID origin to cache LV, properly rename sub-LVs.
systemd: use RemoveOnStop for dm-event.socket and lvm2-lvmetad.socket Systemd version 214 introduced new "RemoveOnStop" option for socket units to remove the socket/FIFO when the particular unit is stopped. Also https://bugzilla.redhat.com/show_bug.cgi?id=802748.
2014-06-13 17:45:25 +04:00
Use RemoveOnStop for lvm2-lvmetad.socket systemd unit.
profile: add thin-generic.profile The thin-generic.profile contains settings for thin/thin pool volumes suitable for generic environment/use containing default settings. This allows users to change the global lvm.conf settings at will and still keep the original settings for volumes that have this thin profile assigned already.
2014-06-13 11:45:26 +04:00
Add thin-generic configuration profile for generic thin settings.
pre-release
2014-06-23 17:03:32 +04:00
Fix crash when reporting empty labels on pvs.
activation: retry cleanup deactivation Enable 'retry' deactivation also in 'cleanup' phase. It shouldn't be mostly needed - however udev now produces more and more completelny non-synchronizable device opens, so even for orphan devices we can't easily predict where udevd opens devices. So it's more preferable here to log error about device being open and retry clean, but let the command proceed.
2014-06-09 12:58:57 +04:00
Use retry_deactivation also when cleaning orphan devices.
pre-release
2014-06-23 17:03:32 +04:00
Wait for client threads when shutting down lvmetad.
Remove PV from cache on pvremove.
Avoid repeatedly reporting of failure to connect to lvmetad.
Introduce MDA_FAILED to permit metadata updates even if some mdas are missing.
WHATS_NEW: For commit 9399b743 (prompt for VG cluster attr change) Minor change, but put a comment in WHATS_NEW anyway.
2014-06-06 07:29:16 +04:00
Prompt when setting the VG cluster attr if the cluster is not setup.
vgextend: allow --yes to skip prompt
2014-05-24 01:33:17 +04:00
Allow --yes to skip prompt in vgextend (worked only with -f).
lvm_init: don't use name mangling for LVM LVM has restricter character set that is allowed for VG-LV names and the dm names constructed do not contain any blacklisted characters that would require name mangling. Also, when any other device-mapper device is scanned that could possibly contain such blacklisted characters, we reference the device by its major:minor instead of dm name (e.g. _device_is_usable fn).
2014-05-22 11:56:44 +04:00
Don't use name mangling for LVM - it never uses dm names with wrong char set.
profiles: remove default.profile and add {command,metadata}_profile_template.profile The "default.profile" name was misleading. It's actually a helper *template* that can be used for copying and further editing to create a new profile. Also, we have separate command and metadata profiles now so the templates are separated as well - we can't mix profile settings from one group with another - such profile is rejected by lvm tools.
2014-05-21 14:32:12 +04:00
Remove default.profile and add {command,metadata}_profile_template.profile.
systemd: use umask 022 for generated systemd units by lvm2-activation-generator
2014-05-21 12:10:24 +04:00
Use proper umask for systemd units generated by lvm2-activation-generator.
lvconvert: check ret code of mirror_remove_missing When mirror_remove_missing() fails, stop repairing mirror.
2014-05-20 14:57:42 +04:00
Check for failing mirror_remove_missing() function.
thin: lvconvert warn before conversion Warn user before converting volume to different type. WARNING: Converting vg/lvol0 logical volume to pool's meta/data volume. THIS WILL DESTROY CONTENT OF LOGICAL VOLUME (filesystem etc.) Since the content of volume is lost we have to query user to confirm such operation. If user is 100% sure, he may use '--yes' to avoid prompts.
2014-05-20 18:21:14 +04:00
Prompt before converting volumes to thin pool and thin pool metadata.
dumpconfig: add --type profilable-command/profilable-metadata, --metadataprofile/--commandprofile The dumpconfig now understands --commandprofile/--profile/--metadataprofile The --commandprofile and --profile functionality is almost the same with only one difference and that is that the --profile is just used for dumping the content, it's not applied for the command itself (while the --commandprofile profile is applied like it is done for any other LVM command). We also allow --metadataprofile for dumpconfig - dumpconfig *does not* touch VG/LV and metadata in any way so it's OK to use it here (just for dumping the content, checking the profile validity etc.). The validity of the profile can be checked with: dumpconfig --commandprofile/--profile/--metadataprofile --validate ...depending on the profile type. Also, mention --config in the dumpconfig help string so users know that dumpconfig handles this too (it did even before, but it was not documented in the help string).
2014-05-20 16:45:20 +04:00
Add dumpconfig --type profilable-{metadata,command} to select profile type.
config: differentiate command and metadata profiles and consolidate profile handling code - When defining configuration source, the code now uses separate CONFIG_PROFILE_COMMAND and CONFIG_PROFILE_METADATA markers (before, it was just CONFIG_PROFILE that did not make the difference between the two). This helps when checking the configuration if it contains correct set of options which are all in either command-profilable or metadata-profilable group without mixing these groups together - so it's a firm distinction. The "command profile" can't contain "metadata profile" and vice versa! This is strictly checked and if the settings are mixed, such profile is rejected and it's not used. So in the end, the CONFIG_PROFILE_COMMAND set of options and CONFIG_PROFILE_METADATA are mutually exclusive sets. - Marking configuration with one or the other marker will also determine the way these configuration sources are positioned in the configuration cascade which is now: CONFIG_STRING -> CONFIG_PROFILE_COMMAND -> CONFIG_PROFILE_METADATA -> CONFIG_FILE/CONFIG_MERGED_FILES - Marking configuration with one or the other marker will also make it possible to issue a command context refresh (will be probably a part of a future patch) if needed for settings in global profile set. For settings in metadata profile set this is impossible since we can't refresh cmd context in the middle of reading VG/LV metadata and for each VG/LV separately because each VG/LV can have a different metadata profile assinged and it's not possible to change these settings at this level. - When command profile is incorrect, it's rejected *and also* the command exits immediately - the profile *must* be correct for the command that was run with a profile to be executed. Before this patch, when the profile was found incorrect, there was just the warning message and the command continued without profile applied. But it's more correct to exit immediately in this case. - When metadata profile is incorrect, we reject it during command runtime (as we know the profile name from metadata and not early from command line as it is in case of command profiles) and we *do continue* with the command as we're in the middle of operation. Also, the metadata profile is applied directly and on the fly on find_config_tree_* fn call and even if the metadata profile is found incorrect, we still need to return the non-profiled value as found in the other configuration provided or default value. To exit immediately even in this case, we'd need to refactor existing find_config_tree_* fns so they can return error. Currently, these fns return only config values (which end up with default values in the end if the config is not found). - To check the profile validity before use to be sure it's correct, one can use : lvm dumpconfig --commandprofile/--metadataprofile ProfileName --validate (the --commandprofile/--metadataprofile for dumpconfig will come as part of the subsequent patch) - This patch also adds a reference to --commandprofile and --metadataprofile in the cmd help string (which was missing before for the --profile for some commands). We do not mention --profile now as people should use --commandprofile or --metadataprofile directly. However, the --profile is still supported for backward compatibility and it's translated as: --profile == --metadataprofile for lvcreate, vgcreate, lvchange and vgchange (as these commands are able to attach profile to metadata) --profile == --commandprofile for all the other commands (--metadataprofile is not allowed there as it makes no sense) - This patch also contains some cleanups to make the code handling the profiles more readable...
2014-05-20 16:13:10 +04:00
Exit immediately with error if command profile is found invalid.
Separate --profile cmd line arg into --commandprofile and --metadataprofile.
Strictly separate command profiles and per-VG/LV profiles referenced in mda.
dumpconfig: fix dumpconfig --type diff used in lvm shell as second and later command The dumpconfig reuses existing config_def_check results in case the check is done during general lvm command context initialization (when enabled by config/checks=1) so dumpconfig does not need to run the same check again during its execution, hence saving some time. However, we don't check for differences from defaults during general lvm command initialization as it's useless at that time. It makes sense only in case when such a check is directly requested (like in the case of lvm dumpconfig --type diff). We need to take care that the reused information was already produced with this "diff" checking before and if not, we need to force the check so the check status also gathers the new "diff" info now. Also, do not do diff checking for any other dumpconfig command that is run after dumpconfig --type diff.
2014-05-19 16:51:11 +04:00
Fix dumpconfig --type diff when run as second and later cmd in lvm shell.
config: fix incorrect profile initialization on cmd context refresh When cmd refresh is called, we need to move any already loaded profiles to profiles_to_load list which will cause their reload on subsequent use. In addition to that, we need to take into account any change in config/profile configuration setting on cmd context refresh since this setting could be overriden with --config. Also, when running commands in the shell, we need to remove the global profile used from the configuration cascade so the profile is not incorrectly reused next time when the --profile option is not specified anymore for the next command in the shell. This bug only affected profile specified by --profile cmd line arg, not profiles referenced from LVM metadata.
2014-05-19 15:59:23 +04:00
Fix wrong profile reuse from previous run if another cmd is run in lvm shell.
pre-release
2014-06-23 17:03:32 +04:00
Move cache description from lvm(8) to new lvmcache(7) man page.
display: print skipped prompt Since decisions in the silent mode may not be always obvious, print skipped prompt with answer 'n'. Also document '-qq' behaviour (single -q only shuts logging, while -qq sets silent mode).
2014-05-15 13:58:49 +04:00
Display skipped prompt in silent mode.
report: export DM_REPORT_FIELD_RESERVED_NAME_{HELP,HELP_ALT} and show help on '<lvm_command> -O help' Share DM_REPORT_FIELD_RESERVED_NAME_{HELP,HELP_ALT} between libdm and any libdm user to handle reserved field names, in this case the virtual field name to show help instead of failing on unrecognized field. The libdm user also needs to check the field name so it can fire proper code in this case (cleanup, exit etc.).
2014-05-15 12:58:05 +04:00
Make reporting commands show help about possible sort keys on '-O help'.
report: Add metadata_percent to lvs_cols.
2014-05-15 11:32:27 +04:00
Add metadata_percent to lvs_cols.
allocation: Fix alloc anywhere with parity. Take account of parity areas with alloc anywhere in _calc_required_extents. Extents beyond area_count were treated incorrectly as mirror logs.
2014-05-14 19:25:43 +04:00
Take account of parity areas with alloc anywhere in _calc_required_extents.
cache: avoid expression overflow Cast data_extents to 64bit so calculation is in 64b arithmetic.
2014-05-07 13:12:05 +04:00
Use proper uint64 casting for calculation of cache metadata size.
signals: better nesting support Support upto 3 levels os nesting signal blocking. As of today - code blocks signals immediatelly when it opens VG in read-write mode - this however makes current prompt usage then partially unusable since user may not 'break' command during prompt (something most user would expect). Until a better fix for prompting is implemented, put in support for signal nesting - thus when prompt enables signal acceptance, make it possible to really break command at this point.
2014-05-02 19:30:27 +04:00
Better support for nesting of blocking signals.
locking: use sigaction signal handling Use sigint_allow/restore function instead of duplicating code and switch to use only sigactiction based signal handling.
2014-05-02 19:27:51 +04:00
Use only sigaction handler and drop duplicate signal handler.
signals: Move sigint handling out to lvm-signal.
2014-05-01 23:07:17 +04:00
Separate signal handling and flock code out into lib/misc.
display: check for dmeventd support When quering for dmeventd monitoring status, check first if lvm2 is configured to monitor to avoid unwanted start of dmeventd process for answering monitoring status.
2014-04-30 12:13:35 +04:00
Don't start dmeventd checking seg_monitor and monitoring is disabled.
pvremove: Catch CTRL-c during prompts.
2014-04-29 11:16:28 +04:00
Catch CTRL-c during pvremove prompts.
lvscan: drop test for snapshosts When showing ACTIVE status for snapshot's origin, avoid testing all its snapshot - it's not useful to tell user origin is inactivate, while it's clearly available and running - just one of its snapshot leg is invalid...
2014-04-28 13:58:26 +04:00
Show correct availability status for snapshot origin in lvscan.
thin: move segment info display to correct code section Relocate info from thin pool and thin volume segments to proper code section for segments. Add discards and thin count status info. Info is shown with 'lvdisplay --maps' (like for other segments).
2014-04-28 13:56:07 +04:00
Move segment thin pool/volume info into segment display 'lvdisplay --maps'.
thin: display info when -tpool is running For percentage display we need -tpool - so check for layered device presence here instead of plain pool device. Also update 'info' - so when pool is 'available' we display open count for -tpool device instead of mostly irrelevant pool. TODO: Maybe we should actually display this open info always? (even when just -tpool is available, but pool is not)
2014-04-28 13:50:38 +04:00
Display thin pool usage even when just thin volume is available.
display: show monitoring status When displaying segments (lvdisplay --maps) show monitoring status when supported by segment.
2014-04-28 13:53:56 +04:00
Display monitoring status for monitorable segments in 'lvdisplay --maps'.
display: use Virtual for virtual LV Emphesize virtual extents for virtual LVs and for those use 'Virtual extents' instead of 'Logical extents', so it's immeditatelly visible, which extents do have straighforward physical backend.
2014-04-28 13:19:51 +04:00
Display virtual extents for virtual LVs in 'lvdisplay --maps'.
vgsplit: Make RAID 4/5/6 fail cleanly when too few PV specified While the 'raid1/10' segment types were being handled inadvertently by '_move_mirrors()', the parity RAIDs were not being properly checked to ensure that the user had specified all necessary PVs when moving them. Thus, internal errors were being triggered when only part of a RAID LV was moved to the new VG. I've added a new function, '_move_raid()', which properly checks over any affected RAID LVs and ensures that all the necessary PVs are being moved.
2014-04-26 01:24:50 +04:00
Make vgsplit fail cleanly when not all PVs are specified for RAID 4/5/6.
WHATS_NEW: Add message for commit 9ac858f WHATS_NEW for commit: 9ac858f vgsplit: Make vgsplit work on mirrors with leg and log on same PV
2014-04-25 23:55:32 +04:00
Make vgsplit work on mirrors with logs that share PVs with images.
config: use devices/ignore_suspended_devices=0 by default ignore_suspended_devices=0 is already used in lvm.conf we distribute, but it was still "1" in the code (so it was used when lvm.conf value was not defined). It should be "0" too.
2014-04-24 14:12:28 +04:00
Use devices/ignore_suspended_devices=0 by default if not defined in lvm.conf.
unknown: fix mempool used for name allocation Use cmd libmem mempool for name allocation, since mem mempool is released after each clvmd command.
2014-04-17 12:42:41 +04:00
Use proper libmem mempool for allocation of unknown segment name.
tools: Add --readonly support. Offer lock-free access to display virtual machine or clustered VG metadata while it might be in use.
2014-04-18 05:46:34 +04:00
Add --readonly to reporting and display tools for lock-free metadata access.
Add locking_type 5 for dummy locking for tools that do not need any locks.
metadata: Fix unlock on VG recovery error path. If lock conversion failed it tried to unlock VG that was no longer locked.
2014-04-18 05:27:16 +04:00
Fix _recover_vg() error path when lock conversion fails.
reports: Use X for unknown LV attr when no dm. It's safer not to tell people an LV is inactive when we aren't sure.
2014-04-18 05:23:39 +04:00
Use X for LV attributes that are unknown when activation disabled.
Only output lvdisplay 'LV Status' field when activation is enabled.
pvscan: Use lvmetad_used(). Config variables that are processed during setup prior to calling into particular tools must not be accessed directly afterwards in case the values already got overridden. _process_config() already used the tests I'm removing here to call lvmetad_set_active() and set up lvmetad_used().
2014-04-18 05:13:46 +04:00
Use lvmetad_used() in pvscan instead of config_tree.
configure: use configure's --enable-udev-systemd-background-jobs by default This should be the preferred way of configuring lvm2 for udev/systemd since otherwise one can end up with the processes run from udev (the pvscan we run for lvmetad update on events) to be killed prematurely and this can end up with LVM volumes not activated in the end.
2014-04-16 13:33:44 +04:00
Configure --enable-udev-systemd-background-jobs if not disabled explicitly.
lvmdump: add -s to gather system info and context (currently systemd-related only) This is sort of info we always ask people to retrieve when inspecting problems in systemd environment so let's have this as part of lvmdump directly. The -s option does not need to be bound to systemd only. We could add support for initscripts or any other system-wide/service tracking info that can help us with debugging problems.
2014-04-15 17:27:30 +04:00
Add lvmdump -s to collect system info and context (currently systemd only).
alloc: Introduce A_POSITIONAL_FILL. Set A_POSITIONAL_FILL if the array of areas is being filled positionally (with a slot corresponding to each 'leg') rather than sequentially (with all suitable areas found, to be sorted and selected from).
2014-04-15 04:13:47 +04:00
Refactor allocation code to make A_POSITIONAL_FILL explicit.
clvmd: use thread-safe ctime_r when debugging Use thread friendly version of ctime TODO:should be probably replaced with strftime()
2014-04-09 09:51:36 +04:00
Use thread-safe ctime_r() for clvmd debug logging.
clvmd: skip adding reply when finished Prior adding new reply to the list, check if the reply thread is not already finished. In that case discard adding message (which would otherwise be leaked).
2014-04-14 14:40:23 +04:00
Skip adding replies to already finished reply thread.
clvmd: improve mutex usage in request_timed_out Use mutex to access localsock values, so check num_replies when the thread is not yet finished. Check for threadid prior the mutex taking (though this check is probably not really needed)
2014-04-14 13:39:24 +04:00
Use mutex to check number of replies in request_timed_out() in clvmd.
clvmd: drop reply_mutex Added complexity with extra reply mutex is not worth the troubles. The only place which may slightly benefit from this mutex is timeout and since this is rather error case - let's convert it to localsock.mutex and keep it simple.
2014-04-09 10:12:13 +04:00
Drop usage of extra reply_mutex for localsock in clvmd.
clvmd: set finished flag with mutex Setting this variable needs to be protected with mutex.
2014-04-09 12:36:25 +04:00
Protect manipulation with finished flag with mutex in clvmd.
clvmd: move mutex init and detroy Move the pthread mutex and condition creation and destroy to correct place right after client memory is allocatedd or is going to be released. In the original place it's been in race with lvm thread which could have still unlock mutex while it's been already destroyed.
2014-04-09 10:06:16 +04:00
Shift mutex creation and destroy for localsock in clvmd to correct place.
clvmd: fix test mode race When TEST_MODE flag is passed around the cluster, it's been use in thread unprotected way, so it may have influenced behaviour of other running parallel lvm commands (activation/deactivation/suspend/resume). Fix it by set/query function only under lvm mutex. For hold_un/lock function calls check lock_flags bits directly.
2014-04-09 09:58:40 +04:00
Fix usage of --test option in clvmd.
memlock: ignore more libraries Extend the list of ignored libraries. Since we do not use those libraries during suspend, skip their locking.
2014-04-10 12:52:44 +04:00
Skip more libraries to be mlocked in memory.
pvmove: remove locked flag from error pvmove0 When pvmove0 is finished, it replaces temporarily pvmove0 with error segment, however in this case, pvmove0 remains unremovable in case pvmove --abort is interrupted in this moment - since it's not a pvmove anymore and normal lvremove can't be used to remove LOCKED lv.
2014-04-10 22:31:39 +04:00
Remove LOCKED flag for pvmove replaced with error target.
polldaemon: ret invalid cmd for negative interval Negative intervals are not supported.
2014-04-10 12:08:09 +04:00
Return invalid command when specifying negative polling interval.

Version 2.02.106 - 10th April 2014
==================================
pvcreate: fix ignored --dataalignment/dataalignment offset for pvcreate --restorefile There were two bugs before when using pvcreate --restorefile together with data alignment and its offset specified: - the --dataalignment was always ignored due to missing braces in the code when validating the divisibility of supplied --dataalignment argument with pe_start which we're just restoring: if (pp->rp.pe_start % pp->data_alignment) log_warn("WARNING: Ignoring data alignment %" PRIu64 " incompatible with --restorefile value (%" PRIu64").", pp->data_alignment, pp->rp.pe_start); pp->data_alignment = 0 The pp->data_alignment should be zeroed only if the pe_start is not divisible with data_alignment. - the check for compatibility of restored pe_start was incorrect too since it did not properly count with the dataalignmentoffset that could be supplied together with dataalignment The proper formula is: X * dataalignment + dataalignmentoffset == pe_start So it should be: if ((pp->rp.pe_start % pp->data_alignment) != pp->data_alignment_offset) { ...ignore supplied dataalignment and dataalignment offset... }
2014-04-10 15:43:46 +04:00
Fix ignored --dataalignment/dataalignment offset for pvcreate --restorefile.
lvmetad: fix lost bootloader area information The refactoring made by 732859d21f3b41bdb188f92b60f25d5c94dcee8a caused this. The former "ea" was not renamed to "ba" and we used incorrect tree node name to search for the value.
2014-04-09 16:42:40 +04:00
Fix lost information about bootloader area when using lvmetad.
tools: don't require --major to be specified when using -My option on kernels > 2.4 Since kernel > 2.4 have dynamically assigned major numbers. [0] raw/~ $ lvcreate -l1 -My --minor 10 vg Logical volume "lvol0" created [0] raw/~ $ lvcreate -l1 -My --major 254 --minor 11 vg Ignoring supplied major number - kernel assigns major numbers dynamically. Using major number 253 instead. Logical volume "lvol1" created [0] raw/~ $ lvs --profile out -o+major,minor lvol0 vg -wima----- 4.00 253 10 lvol1 vg -wima----- 4.00 253 11
2014-04-04 15:29:39 +04:00
Don't require --major to be specified when using -My option on kernels > 2.4.
thin: Support thin_check --clear-needs-check-flag. Update thin provisioning tools to version 0.3.2 or later!
2014-04-04 05:22:40 +04:00
Add configure --disable-thin_check_needs_check to support old thin_check.
Use thin_check --clear-needs-check-flag by default.
lib: Share lvm_even_rand for random numbers.
2014-04-04 04:26:19 +04:00
Export lvm_even_rand() for controlled provision of random numbers.
man: Add lvmthin(7).
2014-04-04 04:14:25 +04:00
Add lvmthin man page to section 7.
pre-release
2014-04-10 19:28:28 +04:00
Ensure mapped device names are not too long in vg_validate and lvrename.
Ensure resume failure in lvrename results in command failure.
Add explicit error message when using lvdisplay -c -m.
Report error if superfluous argument (e.g. PV name) supplied to pvscan.
Fix error message for pvdisplay -c -m and add one for pvdisplay -c -s.
Use EINVALID_CMD_LINE correctly instead of ECMD_FAILED in vgimport/export.
Obtain list of known VGs from lvmetad for pvchange --all.
Add man page for lvm-dumpconfig to section 8.
lv_manip: drop cmd pointer from for_each_sub_lv Drop unused passed cmd pointer from function. TODO: We have two similar functions (though not identical) lv_manip.c: for_each_sub_lv() metadata.c: _lv_each_dependency() They seem to not always match - we should probably convert to use only a single function.
2014-03-27 13:35:07 +04:00
Drop unused cmd pointer for internal function for_each_sub_lv().
lv_rename: validate renamed sublv Use proper vgmem memory pool for allocation of LV name in the vg and check if new renamed LV is a valid name. TODO: validation should really use also VG name, othewise we are not able to tell "vgname-lvname" will be valid.
2014-03-27 13:35:51 +04:00
Validate name for renamed sub LVs.
pre-release
2014-04-10 19:28:28 +04:00
When lvrename fails on argument parsing return EINVALID_CMD_LINE.
pvchange: fix exit code regression Commit 1a832398a7caa96faab2ccbac773cc4047c8f9c1 moved some code from _pvchange_single() to main pvchange() and introduced exit code regression as return codes have not been properly changed, thus pvchange command exited with '0' exit code, even though it has reported error. Also there is a missing vg unlock in error path. Fix it by counting the total number of expected calls before checking for pvname and also unlock and relase vg when pv is not found.
2014-03-27 14:27:42 +04:00
Fix exit code regression in failing pvchange command (2.02.66).
lvmdump: add lvm dumpconfig --type diff/missing For a quick overview of config when debugging and to quickly check which values are different from defaults and which are not defined in the config and for which defaults are used.
2014-03-25 16:06:59 +04:00
Include 'lvm dumpconfig --type missing' and '--type diff' output to lvmdump.
pvresize: fail exit code for negative size Pvresize with negative value retuns invalid cmd line exit code.
2014-03-25 14:52:03 +04:00
Return failure when specifying negative size for pvresize.
dev-cache: fix mem corruption on refresh context When lvm2 command works with clvmd and uses locking in wrong way, it may 'leak' certain file descriptors in opened (incorrect) state. dev_cache_exit then destroys memory pool of cached devices, while _open_devices list in dev-io.c was still referencing them if they were still opened. Patch properly calls _close() function to 'self-heal' from this invalid state, but it will report internal error (so execution with abort_on_internal_error causes immediate death). On the normal 'execution', error is only reported, but memory state is corrected, and linked list is not referencing devices from released mempool. For crash see: https://bugzilla.redhat.com/show_bug.cgi?id=1073886
2014-03-25 13:53:42 +04:00
Fix memory corruption in cmd context refresh if clvmd leaks opened device.
WHATS_NEW: commit f12ee43
2014-03-25 14:00:44 +04:00
Reinitialise lvmcache properly on fork to fix premature polldaemon exit.
dumpconfig: add dumpconfig --type diff to show differences from defaults
2014-03-24 16:19:15 +04:00
Add 'lvm dumpconfig --type diff' to show differences from defaults.
dev-swap: detect swap signature on devices smaller then 2MB Smallest supported size for swap device is 40KB, however current test skipped devices smaller then 4096 sectors (2MB). Since page is in bytes, convert it to sectors before comparing with device size (in sectors).
2014-03-22 23:36:14 +04:00
Fix swap signature detection for devices smaller then 2MB.
WHATS_NEW update
2014-03-22 01:00:54 +04:00
Use dm_malloc function in clvmd.c.
Resolve memory release order for clvmd shutdown.
Report error when lvm2 activation is released in critical_section.
pvscan: fix report of long pv names pvscan --uuid was broken since it was using only 128 char buffers without checking any write size, so any longer device path leads to crash. Also ansure format is properly aligned into columns with this option.
2014-03-19 03:17:36 +04:00
Fix memory corruption when pvscan reports long pv names.
pv_vg_name: do not expose internal orphans to lvm2 users Check for orphan VG name and return just empty string, Use internally pv->vg_name if the real orphan name is needed.
2014-03-19 02:54:46 +04:00
Do not report internal orphan VG names when reporting pvdisplay/pvscan.
pvdisplay: fix man to refer to sectors, not KB The PV size is displayed in sectors, not kilobytes for 'pvdisplay -c' Signed-off-by: Thomas Fehr <fehr@suse.de> Acked-by: Hannes Reinecke <hare@suse.de>
2014-03-18 12:24:01 +04:00
Fix pvdisplay -c man page referencing KB instead of sectors.
clvmd: avoid resending local sync commands Instead of sending repeatedly LOCAL_SYNC commands to clvmds like 'lvs', rememeber the last sent commmand, and if there was no other clvmd command, drop this redundant SYNC call message. The problem has started with commit: 56cab8cc037fc4d31085705987b3a4c04d5e5938 This introduced correct synchronisation of name, when user requests to know open_count (needs to wait for udev), however it is also executed for read-only cases like 'lvs' command. For now implement very simple solution, which is only monitoring outgoing clvmd command, and when sequence of LOCAL sync names are recognized, they are skipped automatically. TODO: Future solution might move this variable info 'cmd_context' and use 'needs_sync' flag also i.e. in file locking code.
2014-03-19 03:25:51 +04:00
Skip redundant synchronization calls on local clvmd.
file_locking: use PATH_MAX for dir name Using just 128 chars for locking dir may wail if longer dir entry is used, swich to default linux max path.
2014-03-19 03:22:18 +04:00
Use correct PATH_MAX for locking dir path.
archiver: drop unneeded backup check When the backup is disabled, avoid testing backup presence. This only leads to errors being logged in debug trace and the missing backup can't be fixed, since it's disabled.
2014-03-19 03:20:39 +04:00
Do not check for backups when when its creation is disabled.
dumpconfig: fix memleak when using --mergedconfig Check whether lvm dumpconfig --mergedconfig is used only with --type current (where we're merging current config and the config supplied on command line). With other types the config was merged, but it was thrown away since we're generating other type of config anyway. This lead to a memleak. Error out if --mergedconfig is used with anything else than --type current (or without specifying --type in which case the --type current is used by default).
2014-03-18 14:04:21 +04:00
Don't allow --mergedconfig without --type current in dumpconfig. Fix memleak.
config: make global/lvdisplay_shows_full_device_path profilable
2014-03-18 12:49:53 +04:00
Make global/lvdisplay_shows_full_device_path lvm.conf setting profilable.
WHATS_NEW: previous commit
2014-03-18 12:28:52 +04:00
Make global/{units|si_unit_consistency|suffix} lvm.conf setting profilable.
lvconvert: validate min chunk size for snapshot Do not allow conversion of too small LV into a COW snapshot device. Without this patch snapshot target is generating these kernel messages before creation fails: attempt to access beyond end of device dm-9: rw=16, want=8, limit=2 attempt to access beyond end of device ... device-mapper: table: 253:11: snapshot: Failed to read snapshot metadata device-mapper: ioctl: error adding target to table device-mapper: reload ioctl on failed: Input/output error
2014-03-17 16:06:00 +04:00
Validate minimal chunk size for snapshot COW volume in lvconvert.
lvconvert: disallow usage of origin for snapshot Usage of origin as a snapshot 'COW' volume is unsupported. Without this test lvm2 is able to generate this ugly internal error message. To test this: lvcreate -L1 -n lv1 vg lvcreate -L1 -n lv2 -s vg/lv1 lvcreate -L1 -n lv3 vg lvconvert -s vg/lv3 vg/lv1 Internal error: LVs (5) != visible LVs (1) + snapshots (1) + internal LVs (0) in VG vg
2014-03-17 12:41:36 +04:00
Disallow lvconvert of origin to snapshot COW volume.
config: make global/units and global/si_unit_consistency profilable
2014-03-17 19:03:53 +04:00
Make report lvm.conf settings profilable.
conf: add existing report settings to lvm.conf These settings exist for ages but they were not exposed in lvm.conf and so majority of users didn't event know about them.
2014-03-17 17:24:21 +04:00
Add existing report settings to lvm.conf.
autoactivation: use VG read lock The activation (including the refresh) should take the VG read lock like the usual activation/refresh.
2014-03-14 15:07:41 +04:00
Use VG read lock during 'pvscan --cache -aay' autoactivation.
autoactivation: issue a VG refresh before autoactivation only if 'change' lvmetad flag is set This prevents numerous VG refreshes on each "pvscan --cache -aay" call if the VG is found complete. We need to issue the refresh only if the PV: - is new - was gone before and now it reappears (device "unplug/plug back" scenario) - the metadata has changed
2014-03-14 13:44:14 +04:00
Issue a VG refresh before autoactivation only if the PV has changed/is new.
Add flag to lvmetad protocol to indicate the PV scanned has changed/is new.
WHATS_NEW: commit 5eef269
2014-03-19 12:49:09 +04:00
Also add vgname to lvmetad protocol when referencing VGs for PVs scanned.
man: add man page for lvm2-activation-generator
2014-03-13 16:01:06 +04:00
Add man page for lvm2-activation-generator.
config: accept empty values for global/thin_disabled_features Let's do this the other way round - this makes more logic than commit b995f06. So let's allow empty values for global/thin_disabled_features where such an empty value now means "none of this features are disabled".
2014-03-12 18:53:20 +04:00
Don't print an error and accept empty value for global/thin_disabled_features.
lvm: change build_dm_uuid API Pass directly 'lv' into this build routine, so we can eventually add more private UUID suffixes.
2014-03-11 20:13:47 +04:00
Update API for internal function build_dm_uuid().
thin: do not check of empty pool with messages The empty pool is also the pool which has yet queued list of messages and transaction_id == 1. Problem is exposed when pool is created inactive. lvcreate -L10 -T vg/pool -an lvcreate -V10 -T vg/pool
2014-03-12 01:54:33 +04:00
Do not try to check empty pool with scheduled messages.
thin: fix pool_has_message return for NULL params When pool_has_message() is queried with NULL lv and 0 device_id it should just return 'true' when there is any message queued. So it needs to return negative value dm_list_empty(). Since there is no user for this code path in code currently, this bug has not been triggered.
2014-03-12 01:50:23 +04:00
Fix return value in pool_has_message() when quering for any message.
clvmd: fix memleak on exit This patch will releases allocated private resources from startup. Needs previous dm_zalloc patch to ensure unset private pointer is NULL. TODO: check on real cluster.
2014-03-09 02:16:31 +04:00
Cleanup all client resources on clvmd exit.
clvmd: use dm_zalloc for socket allocation Instead of doing individual settings for struct members, ensure whole struct is in defined state.
2014-03-09 01:55:47 +04:00
Use dm_zalloc to clear members of clvmd client struct.
makefiles: use BLKID/UDEV_CFLAGS properly blkid.h needs BLKID_CFLAGS Do not add UDEV_CFLAGS everywhere and use it only when needed.
2014-03-06 19:03:08 +04:00
Use BLKID_CFLAGS when compiling with blkid support.
readline: switch to new-style readline typedef Based on patch: https://www.redhat.com/archives/lvm-devel/2014-March/msg00015.html The CPPFunction typedef (among others) have been deprecated in favour of specific prototyped typedefs since readline 4.2 (circa 2001). It's been working since because compatibility typedefs have been in place until they where removed in the recent readline 6.3 release. Switch to the new style to avoid build breakage. But also add full backward compatibility with define. Signed-off-by: Gustavo Zacarias <gustavo zacarias com ar>
2014-03-06 19:04:19 +04:00
Use correct rl_completion_func_t typedef for new readline.
WHATS_NEW: config handling changes
2014-03-06 16:03:51 +04:00
Make lvm 'dumpconfig --type default' complete for it to be consumed by lvm.
udev: run pvscan --cache via systemd-run in udev if the PV label is detected lost If the PV label is lost (e.g. by doing a dd on the device), call "systemd-run pvscan --cache <major>:<minor>" in 69-dm-lvm-metad.rules to inform lvmetad about this state. The reason for this is that ENV{SYSTEMD_WANTS}="lvm2-pvscan@<major>:<minor>" logic will not cause the pvscan to be fired in this case since this works only on proper device addition/removal cycle - the lvm2-pvscan service's ExecStop is called only on proper REMOVE event - the service is bound to device existence. Hence we need pvscan call via systemd-run (that instantiates a quick transient service just to call the command). See also https://bugzilla.redhat.com/show_bug.cgi?id=1063813.
2014-03-05 17:25:08 +04:00
Run pvscan --cache via systemd-run in udev if the PV label is detected lost.
lvmetad: fix memleak when pv changes it device Test vgimportclone invokes mem leak of pvid which would be otherwise lost when device_old_pvid is removed from hash table.
2014-03-01 14:36:05 +04:00
Fix memleak when lvmetad discovers PV to appear on another device.
snapshots: fix incorrect calculation of cow size Code uses target driver version for better estimation of max size of COW device for snapshot. The bug can be tested with this script: VG=vg1 lvremove -f $VG/origin set -e lvcreate -L 2143289344b -n origin $VG lvcreate -n snap -c 8k -L 2304M -s $VG/origin dd if=/dev/zero of=/dev/$VG/snap bs=1M count=2044 oflag=direct The bug happens when these two conditions are met * origin size is divisible by (chunk_size/16) - so that the last metadata area is filled completely * the miscalculated snapshot metadata size is divisible by extent size - so that there is no padding to extent boundary which would otherwise save us Signed-off-by:Mikulas Patocka <mpatocka@redhat.com>
2014-02-25 22:43:07 +04:00
Fix calculation of maximum size of COW device for snapshot (2.02.99).
lvresize: fix stripe size validation While stripe size is twice the physical extent size, the original code will not reduce stripe size to maximum (physical extent size). Signed-off-by: Zhiqing Zhang <zhangzq.fnst@cn.fujitsu.com>
2014-02-26 06:14:18 +04:00
Do not allow stripe size to be bigger then extent size for lvresize.
snapshot: zero cow header for read-only snapshot When read-only snapshot was created, tool was skipping header initialization of cow device. If it happened device has been already containing header from some previous snapshot, it's been 'reused' for a newly created snapshot instead of being cleared.
2014-02-26 03:17:11 +04:00
Zero snapshot COW header when creating read-only snapshot.
dumpconfig: comment out config lines without default values defined To make "lvm dumpconfig --type default" output to be usable like any other config, we need to comment out lines that have no default value defined. Otherwise, we'd have the output with config options with blank or zero values which is not the same as when the value is not defined! And such configuration can't be feed into lvm again without further edits. So let's fix this. Currently this covers these configuration options exactly: devices/loopfiles devices/preferred_names devices/filter devices/global_filter devices/types allocation/cling_tag_list global/format_libraries global/segment_libraries activation/volume_list activation/auto_activation_volume_list activation/read_only_volume_list activation/mlock_filter metadata/dirs metadata/disk_areas metadata/disk_areas/<disk_area> metadata/disk_areas/<disk_area>/start_sector metadata/disk_areas/<disk_area>/size metadata/disk_areas/<disk_area>/id tags/<tag> tags/<tag>/host_list
2014-02-25 14:05:23 +04:00
Comment out config lines in dumpconfig output without default values defined.
mirror: detect attrs just once Reorder detection of cmirrord. Now if cmirrord is not running, target will not try to load kernel log module, for communication with cmirrord. Whole check for attrs now also happens just once.
2014-02-24 17:18:26 +04:00
Improve detection of clustered mirror support.
raid: use feature attributes for raid10 Test raid10 availability as a target feature (instead of doing it in all the places where raid10 should be checked). TODO: activation needs runtime validation - so metadata with raid10 are skipped from activation in user-friendly way in lvm2.
2014-02-24 16:15:40 +04:00
Enhance raid code with feature flags, for now checks for raid10.
metadata: move vg parsing to vg_write Parsing vg structure during supend/commit/resume may require a lot of memory - so move this into vg_write. FIXME: there are now multiple cache layers which our doing some thing multiple times at different levels. Moreover there is now different caching path with and without lvmetad - this should be unified and both path should use same mechanism.
2014-02-22 04:44:21 +04:00
Move parsing of VG metadata from vg_commit() back to vg_write() (2.02.99)
WHATS_NEW: for commit b391ae88e5ed3720a8b5a87312e0cd907a94fcc2
2014-02-21 14:36:55 +04:00
Avoid a PV label scan while in a critical section.
activation: lv_activation_skip remove always same arg. Remove 'skip' argument passed into the function. We always used '0' - as this is the only supported option (-K) and there is no complementary option. Also add some testing for behaviour of skipping.
2014-02-19 14:02:16 +04:00
Remove (always 0) skip argument from lv_activation_skip().
udev: create /dev/disk/by-id/lvm-pv-uuid-<PV_UUID> symlink for a PV We already have /dev/disk/by-id/dm-uuid-... (which encompasses the VG UUID and LV UUID in case of LVs since the mapping's UUID is VG+LV UUID together) and /dev/disk/by-id/dm-name-... (which encompasses the VG and LV name in case of LVs). This patch addds /dev/disk/by-id/lvm-pv-uuid-<PV_UUID> that completes this scheme and makes navigation a bit easier using PV UUIDs since one can navigate using PV UUIDs only and there's no need to do extra PV UUID <--> kernel name matching (the PV UUID is stable across reboots). This may come in handy in various scripts. Since we already have the PV UUID stored in udev database (as a result of blkid call - returned in ID_FS_UUID blkid's variable), this operation is very cheap indeed, just creating the extra one symlink.
2014-02-18 14:27:21 +04:00
Create /dev/disk/by-id/lvm-pv-uuid-<PV_UUID> symlink for each PV via udev.
RAID: Allow implicit stripe (and parity) when creating RAID LVs There are typically 2 functions for the more advanced segment types that deal with parameters in lvcreate.c: _get_*_params() and _check_*_params(). (Not all segment types name their functions according to this scheme.) The former function is responsible for reading parameters before the VG has been read. The latter is for sanity checking and possibly setting parameters after the VG has been read. This patch adds a _check_raid_parameters() function that will determine if the user has specified 'stripe' or 'mirror' parameters. If not, the proper number is computed from the list of PVs the user has supplied or the number that are available in the VG. Now that _check_raid_parameters() is available, we move the check for proper number of stripes from _get_* to _check_*. This gives the user the ability to create RAID LVs as follows: # 5-device RAID5, 4-data, 1-parity (i.e. implicit '-i 4') ~> lvcreate --type raid5 -L 100G -n lv vg /dev/sd[abcde]1 # 5-device RAID6, 3-data, 2-parity (i.e. implicit '-i 3') ~> lvcreate --type raid6 -L 100G -n lv vg /dev/sd[abcde]1 # If 5 PVs in VG, 4-data, 1-parity RAID5 ~> lvcreate --type raid5 -L 100G -n lv vg Considerations: This patch only affects RAID. It might also be useful to apply this to the 'stripe' segment type. LVM RAID may include RAID0 at some point in the future and the implicit stripes would apply there. It would be odd to have RAID0 be able to auto-determine the stripe count while 'stripe' could not. The only draw-back of this patch that I can see is that there might be less error checking. Rather than informing the user that they forgot to supply an argument (e.g. '-i'), the value would be computed and it may differ from what the user actually wanted. I don't see this as a problem, because the user can check the device count after creation and remove the LV if they have made an error.
2014-02-18 06:18:23 +04:00
lvcreate computes RAID4/5/6 stripes if not given from # of allocatable PVs.
thin: fix merge of old snaphost Fix merging of old snapshot into thinvolume origin. Add also internal error for the error case when merging requests activation of merged LV.
2014-02-18 00:48:27 +04:00
Fix merging of old snapshot into thin volume origin.
scripts: use --ignoreskippedcluster in lvm2-monitor initscript/systemd unit When clustered VG is available in the system but we don't have clustering set up for whatever reason, the lvm2-monitor scripts should not fail completely just because these clustered VGs are skipped during vgs/vgchange calls in lvm2-monitor initscript/systemd unit.
2014-02-17 19:25:32 +04:00
Use --ignoreskippedcluster in lvm2-monitor initscript/systemd unit.
activation: drop test r/w vg state for activing LV VG status read/write is meant to influence only VG metadata. It's not related to the read/write status of the LV itself.
2014-02-13 17:42:29 +04:00
Do not use VG read/write state for LV read/write state.
systemd: Use --ignoreskippedcluster in generated activation systemd units When the activation units are generated if use_lvmetad=0 (no autoactivation), use --ignoreskippedcluster option for vgchange calls since the cluster with cLVM is set up by separate units. This avoids a situation in which the generated activation units are improperly in failed state just because of the vgchange return value when clustered VGs are encountered while the activation of non-clustered VGs does proceed normally.
2014-02-14 14:59:12 +04:00
Use --ignoreskippedcluster in activation systemd units if use_lvmetad=0.
Update WHATS_NEW for approximate allocation check-in
2014-02-14 07:12:28 +04:00
Allow approximate allocation when specifying size in percentage terms.
cache[pool]: Man page updates for lvs, lvcreate, lvconvert
2014-02-12 20:29:07 +04:00
Add basic LVM support for cache[pool] segment types.
raid: drop invalid modication of active parameter lv_active_change will enforce proper activation. Modification of activation was wrong and lead to misuse of autoactivation. Fix allows to use proper local exclusive activation, while the removed code turned this into just exclusive activation (losing required local property).
2014-02-11 16:34:22 +04:00
Use local exclusive activation for creation of raid in cluster.
raid: use unsigned 64b constant for shift
2014-02-10 00:34:55 +04:00
Use correctly signed 64b constant when selecting raid volumes.
cleanup: clarify man pages about lvchange/vgchange -aay, use -aay in lvm2-cluster-activation script
2014-02-11 16:48:04 +04:00
Add systemd native service for clvmd, cmirrord and clustered LV activation.
systemd: cleanup for lvmetad systemd unit No need to fork lvmetad when running under systemd. Also, the "lvmetad -R" support has been removed in lvm2 v2.02.98 so remove the ExecReload line that called it on "systemctl reload".
2014-02-10 19:18:48 +04:00
Remove ExecReload from lvmetad systemd unit: lvmetad -R undefined. (2.02.98)
Do not fork lvmetad if running under systemd.
wiping: wipe DM_snapshot_cow signature without prompt in newly created LVs The libblkid can detect DM_snapshot_cow signature and when creating new LVs with blkid wiping used (allocation/use_blkid_wiping=1 lvm.conf setting and --wipe y used at the same time - which it is by default). Do not issue any prompts about this signature when new LV is created and just wipe it right away without asking questions. Still keep the log in verbose mode though.
2014-02-10 16:28:13 +04:00
Wipe DM_snapshot_cow signature without prompt in new LVs with blkid wiping.
raid: add temporary activation for raid metadata clear Use LV_TEMPORARY when activating devices for clearing raid metadata.
2014-02-04 17:47:52 +04:00
Avoid exposing temporary devices when initializing raid metadata volumes.
tools: Add internal tags command.
2014-01-30 17:09:15 +04:00
Add internal tags command to display any tags defined on the host.
thin: validate external origin size Avoid use of external origin with size unaligned/incompatible with thin pool chunk size, since the last chunk is not correctly provisioned when it is overwritten.
2014-01-29 17:27:13 +04:00
Prohibit use of external origin with size incompatible with thin pool.
thin: more validation of thin name Avoid starting conversion of the LV to the thin pool and thin volume at the same time. Since this is mostly a user mistake, do not try to just convert to one of those type, since we cannot assume if the user wanted LV to become thin volume or thin pool. Before the fix tool reported pretty strange internal error: Internal error: Referenced LV lvol1_tdata not listed in VG mvg. Fixed output: lvconvert --thinpool lvol0 -T mvg/lvol0 Can't use same LV mvg/lvol0 for thin pool and thin volume.
2014-01-28 16:21:39 +04:00
Avoid trying to convert single to thin pool and volume at the same time.
devices: support zvol Support partitions on ZFS zvol. Requested via https://bugzilla.redhat.com/show_bug.cgi?id=913597 Author: hakimian@aha.com
2014-01-27 16:13:32 +04:00
Add support for partitions on ZFS zvol.
locking: avoid dropping locks When lvm2 command forks, it calls reset_locking(), which as an unwanted side effect unlinked lock file from filesystem. Patch changes the behavior to just close locked file descriptor in children - so the lock is being still properly hold in the parent.
2014-01-27 15:11:09 +04:00
Fix unwanted drop of hold flocks on forked children.
lvmetad: respect LVM_LVMETAD_PIDFILE settings in lvm Test LVM_LVMETAD_PIDFILE for pid for lvm command. Fix WHATS_NEW envvar name usage Fix init order in prepare_lvmetad to respect set vars and avoid clash with system settings. Update test to really test the 'is running' message.
2014-01-24 18:59:38 +04:00
Respect LVM_LVMETAD_PIDFILE env var for lvm command.
thin: use LV_TEMPORARY for metadata initialization This flag need to be specified when we create thin pool - to avoid scanning device with watch rules.
2014-01-24 15:28:35 +04:00
Avoid exposing temporary devices when initializing thin pool volume.
thin: fix feature compare function Comparing for available feature missed the code path, when maj is already bigger. The bug would be only hit in the case, thin pool target would have increased major version.
2014-01-23 16:47:23 +04:00
Fix test when checking target version for available thin features.
thin: validate resize of thin LV with ext. origin When thin volume is using external origin, current thin target is not able to supply 'extended' size with empty pages. lvm2 detects version and disables extension of LV past the external origin size in this case. Thin LV could be however still reduced and extended freely bellow this size.
2014-01-23 16:10:29 +04:00
Detect thin feature external_origin_extend and limit extend when missing.
thin: rename function Rename pool_can_resize_metadata() to more reusable thin_pool_feature_supported() which could be queried for mutiple different features.
2014-01-23 14:47:10 +04:00
Rename internal pool_can_resize_metadata() to thin_pool_feature_supported().
wiping: issue error if libblkid detects signature and fails to return offset/length We need both offset and length when trying to wipe detected signatures. The libblkid can fail so it's good to have an error message issued for this state instead of being silent (libblkid does not issue any error messages here). We just issued "stack" here before but that was not quite useful if some error occurs...
2014-01-22 19:26:49 +04:00
Issue error if libbblkid detects signature and fails to return offset/length.
autoconf: Update config.guess/sub to 2014-01-01.
2014-01-22 02:00:15 +04:00
Update autoconf config.guess/sub to 2014-01-01.
thin: online metadata resize requires 1.10 Version 1.10 starts to look promissing, let's enable online resize when this thin-pool kernel target is present.
2014-01-21 16:48:57 +04:00
Online thin pool metadata resize requires 1.10 kernel thin pool target.

pre-release
2014-01-20 23:22:56 +04:00
Version 2.02.105 - 20th January 2014
====================================
Fix thin LV flagging for udev to skip scanning only if the LV is wiped.
Replace use of xfs_check with xfs_repair in fsadm.
format1: Mark obsolete and do not use with lvmetad. DO NOT USE LVMETAD IF YOU HAVE ANY LVM1-FORMATTED PVS. You may continue to use it without lvmetad, but do please schedule an upgrade to the lvm2 format (with 'vgconvert'). Sending the original LVM1 formatted metadata to lvmetad is breaking assumptions made by the code, so I am marking the format as obsolete for now and no longer sending it to lvmetad. This means that if you are using lvmetad, lvm1 volumes will usually appear invisible - though not always: it depends on exactly what sequence of commands you run! The current situation is not satisfactory. We'll either fix lvmetad and reenable this or we'll fix the code to issue appropriate warning messages when lvm1 PVs are encountered to avoid accidents. (The latest unfixed problem is that lvmetad assumes metadata sequence numbers exist and always increase - but the lvm1 format does not define or store any sequence number, confusing both the daemon and client when default values get passed to-and-fro.)
2014-01-14 07:27:45 +04:00
Mark lvm1 format metadata as FMT_OBSOLETE. Do not use it with lvmetad.
lvmcache: Invalidate cached VG if PV is orphaned. If a PV in an existing VG becomes orphaned (with 'pvcreate -ff', for example) the VG struct cached against its vginfo must be invalidated. This is because the struct device it references no longer contains the PV label so becomes incorrect. This triggers the error: Internal error: PV $dev unexpectedly not in cache. when the PV from the cached VG metadata is subsequently looked up in the cache. Bug introduced in 2.02.87 by commit 7ad0d47c3c93053c07c45161dbdbc0798ac7e2f6 ("Cache and share generated VG structs").

2014-01-14 06:57:03 +04:00
Invalidate cached VG struct after a PV in it gets orphaned. (2.02.87)
Mark pool format metadata as FMT_OBSOLETE.
systemd: use only major:minor for pvscan in lvm2-pvscan@.service When using filters for the pvscan --cache (the global_filter), there's a difference between: pvscan --cache -aay /dev/block/<major>:<minor> and pvscan --cache -aay <major>:<minor> (or --major <major> --minor <minor>) In the first case, we need to be sure to have an exact matching line in the filter for the device to be used, no aliases are considered So for example even if we have accept rule for "/dev/sda" present, this won't apply for "/dev/block/8:0" even though it's the same device! This is because we're comparing the path used on command line directly with the path written in the rule. For the second one, any alias mentioned in the filter will apply as we're comparing the major and minor pair, not looking at actual device names - so any alias mentioned in the rules will suffice for the filtering rule to apply. For the global_filter to be properly used, we need to call the second one in the lvm2-pvscan@.service - nobody is able to tell what value of major:minor the kernel assignes next time, hence this bug makes the use of global_filter quite unusable!
2013-12-18 15:00:02 +04:00
Use major:minor in lvm2-pvscan@.service for proper global_filter application.
man: syntax and spelling fixes.
2013-12-17 22:26:10 +04:00
Syntax and spelling fixes in some man pages.
lv_dependency: scan also snapshots and extorigins When LV is scanned for its dependencies - scan also origin's snapshots, and thin external origins. So if any PV from snapshot or external origin device is missing - lvm2 will avoid trying to activate such device.
2013-12-17 16:53:15 +04:00
Dependency scan counts with snapshots and external origins.
device: add physical block size info and make sure VG extent size >= PV's phys. block size
2013-12-12 14:26:35 +04:00
Make sure VG extent size is always greater or equal to PV phys. block size.
dev-cache: skip double stat() call on each _insert When the device is inserted in dev_name_confirmed() stat() is called twice as _insert() has it's own stat() call. Extend _insert() parameter with struct stat* - which could be used if it has been just obtained. When NULL is passed code is doing its own stat() call as before.
2011-11-25 13:01:37 +04:00
Optimize double call of stat() for cached devices.
thin: enable build of thin provisioning by default Use internal type by default for thin provisioning. If user is not interested in thin provisiong and doesn't have thin provisining supporting tools installed, configure will just print warning at the end of configure process about limited support.
2013-12-12 16:07:59 +04:00
Enable support for thin provisioning for default configuration.
cleanup: improve tag processing Boolean algebra changes for process_each_lv_in_vg(). 1st. Drop process_lv variable since it's not needed. 2nd. process_lv was always initilized to 0 - so the condition was always true. It the condition (!tags_supplied && !lvargs_supplied) evaluates as "true", process_all is already set to 1, so skip vg tags evaluation. 3rd. Move check for matching lv name in the front of lv tags check since this check can't be skipped for lvargs_matched counter. If this filter evaluates to true, skip lv tags evaluation.
2011-11-09 02:29:40 +04:00
Improve process_each_lv_in_vg() tag processing.

Reordered and simplified logging code.
WHATS_NEW: commit 4c267c7286145165dfe078f77d18d194a21a2e1c See also https://bugzilla.redhat.com/show_bug.cgi?id=1026860 for more info, comment 76 for summary.
2013-12-11 19:50:52 +04:00
Fix SYSTEMD_READY assignment for foreign devices in lvmetad udev rules.
thin: thin metadata resize unsupported with 1.9 Thin kernel target 1.9 still does not support online resize of thin pool metadata properly - so disable it with expectation for much higher version - and reenable after fixing kernel.
2013-12-10 14:10:53 +04:00
Disable online thin pool metadata resize for 1.9 kernel thin target.
cleanup: shorter raid initialization Avoid multiple queries for raid library for each initialized raid seg type and use shorter code.
2013-12-06 19:38:11 +04:00
Shortened code for initialization of raid segment types.
cleanup: tiny speedup of lib_dir checking Instead of repeated lookup of global/library_dir - remember first search in command context - saves couple lines in debug output...
2013-12-06 19:35:54 +04:00
Cache global library dir in command context.
dev-cache: return success when ignoring dirs When there is no failure from the insert operation itself, just dirs and links are skipped - return success.
2013-12-05 14:11:26 +04:00
Return success when inserting dirs and links into device cache.
vgchange: move detection of remote exlusivness Since activation takes only read-lock, there could be multiple activation running in parallel. So instead of checking before taking any real lock, let the locking resolve the problem and just detect if the reason for failure has been remote exlusive activation. It should be also faster, since each activation does not need to do explicit lock query.
2013-11-29 02:22:03 +04:00
Test for remote exclusive activation after activation fails.
thin: enable thin snapshot merge
2013-11-30 00:28:18 +04:00
Support lvconvert --merge for thin snapshots.
thin: read table line with thin device id Add functions to parse thin table line to obtain thin device id.
2013-12-04 16:57:27 +04:00
Add support to read thin device id from table line entry.
merge: test only for meging origin It's enough to check only for merging origin. This will be also used for thin volume merges which do not need to be origins.
2013-11-29 14:01:02 +04:00
Drop extra test for origin when testing merging origin in lv_refresh().
lv_remove_single: add silent arg Support silence for removal message.
2013-11-29 20:00:55 +04:00
Extend lv_remove_single() to not print info about removed LV.
snapshots: use lv_check_not_in_use Switch from a simple 'open_count' test on opened snaphost to a more 'skilled' lv_check_not_in_use().
2013-11-29 18:02:57 +04:00
Replace open_count check with lv_check_not_in_use() for snapshot open test.
refresh: print error message with failing lv name If there is suspend/resume error, print error message with lv name. Drop goto.
2013-11-29 14:10:41 +04:00
Add error messages with LV names for failing lv refresh.
compile/link: use RELRO/PIE compiler/linker options for executables
2013-12-05 17:03:10 +04:00
Compile/link executables with new RELRO and PIE options (non-static builds).
make: support per-object defines In the case we have a dir with multiple objects and for an individual object file we need special define - allow to define it without adding extra rules. To ensure dmeventd.o compilation will use EXTRA_FLAGS: CFLAGS_dmeventd.o += $(EXTRA_FLAGS) Then it's better to use: dmeventd.o: CFLAGS += $(EXTRA_FLAGS)
2013-12-04 15:35:02 +04:00
Support per-object compilation cflags via CFLAGS_object.o.
configure: check compiler/linker support for RELRO and PIE options Also, add AC_TRY_LDFLAGS m4 macro to help with checking ld flags.
2013-12-04 12:58:58 +04:00
Automatically detect support for compiler/linker options to use RELRO and PIE.
lvconvert: Implement --splitsnapshot.
2013-12-04 06:09:37 +04:00
Add --splitsnapshot to lvconvert to separate out cow LV.
lvconvert: Fix reload after snapshot conversion. At the end of lvconvert --snapshot with an active origin, the origin gets reloaded. Commit 57c0f72b1d0349382c226c2b5614489b59db99e8 ("lvconvert: use _reload_lv on more places") accidentally replaced this with a snapshot LV reload (which does nothing because only the origin is active).
2013-12-04 06:04:29 +04:00
Reinstate origin reload to complete lvconvert -s with active LVs. (2.02.98)
vgdisplay: select only active volumes groups if -A option is used Where "active" means "at least one LV is active in the volume group".
2013-12-03 17:41:25 +04:00
Select only active volume groups if vgdisplay -A is used.
lvmetad: respect LVM_LVMETAD_PIDFILE settings in lvm Test LVM_LVMETAD_PIDFILE for pid for lvm command. Fix WHATS_NEW envvar name usage Fix init order in prepare_lvmetad to respect set vars and avoid clash with system settings. Update test to really test the 'is running' message.
2014-01-24 18:59:38 +04:00
Add -p and LVM_LVMETAD_PIDFILE env var to lvmetad to change pid file.
lvmetad: extend socket/pid file handling Make it easier to run a live lvmetad in debugging mode and to avoid conflicts if multiple test instances need to be run alongside a live one. No longer require -s when -f is used: use built-in default. Add -p to lvmetad to specify the pid file. No longer disable pidfile if -f used to run in foreground. If specified socket file appears to be genuine but stale, remove it before use. On error, only remove lvmetad socket file if created by the same process. (Previous code removes socket even while a running instance is using it!)
2013-11-30 00:56:29 +04:00
Allow lvmetad to reuse stale socket.
Only unlink lvmetad socket on error if created by the same process.
lvmetad: Add newline to missing socket error mesg
2013-11-28 23:16:25 +04:00
Append missing newline to lvmetad missing socket path error message.
all: fix typos
2020-10-03 14:52:37 +03:00
Check for non-zero alignment in _text_pv_add_metadata_area() to not div by 0.
conf: add allocation/use_blkid_wiping Add allocation/use_blkid_wiping setting to lvm.conf to select between LVM2 native code to detect signatures to wipe or blkid library code.
2013-11-27 16:52:15 +04:00
Add allocation/use_blkid_wiping to lvm.conf to enable blkid wiping.
configure: enable blkid_wiping by default if the blkid library is present
2013-11-29 18:27:56 +04:00
Enable blkid_wiping by default if the blkid library is present.
Add configure --disable-blkid_wiping to disable libblkid signature detection.

2013-11-06 19:05:50 +04:00
Add -W/--wipesignatures lvcreate option to support wiping on new LVs.
config: shorten new sig wiping option string Rename wipe_signatures_on_new_logical_volumes_when_zeroing to wipe_signatures_when_zeroing_new_lvs.
2013-12-09 13:35:47 +04:00
Add allocation/wipe_signatures_when_zeroing_new_lvs to lvm.conf.
WHATS_NEW: commit 729b104
2013-11-27 11:33:02 +04:00
Do not fail the whole autoactivation if the VG refresh done before fails.
lv/vgchange: do not try to connect to lvmetad if socket absent and --sysinit -aay used If using lv/vgchange --sysinit -aay and lvmetad is enabled, we'd like to avoid the direct activation and rely on autoactivation instead so it fits system initialization scripts. But if we're calling lv/vgchange --sysinit -aay too early when even lvmetad service is not started yet, we just need to do the direct activation instead without printing any error messages (while trying to connect to lvmetad and not finding its socket). This patch adds two helper functions - "lvmetad_socket_present" and "lvmetad_used" which can be used to check for this condition properly and avoid these lvmetad connections when the socket is not present (and hence lvmetad is not yet running).
2013-11-26 17:51:23 +04:00
Do not connect to lvmetad on vg/lvchange --sysinit -aay and socket absent.
snapshot: use lv_check_not_in_use Instead of plain open_count check, try to use 'smarter' lv_check_not_in_use() function.
2013-11-22 18:27:47 +04:00
Use lv_check_not_in_use() when testing device in use before merging.
snapshot: revert and move check to lvconvert Revert 4777eb68728859a0b3651e29c628111ed7c99103 which put target_present check into init_snapshot_merge(). However this function is also used when parsing metadata. So we would get this present test performed even when target is not really needed. So move this target_present test directly into lvconvert.
2013-11-22 17:52:35 +04:00
Move test for target present from init_snapshot_merge() to lvconvert.
pv_write: check for lvmcache_add_mda failure Add missing test of failing lvmcache_add_mda() call.
2013-11-22 16:25:27 +04:00
Check for failure of lvmcache_add_mda() when writing pv.
report: detect dev_get_size failure Since dev_get_size() may fail, detect this failure.
2013-11-22 16:21:52 +04:00
Check for failure of dev_get_size() when reporting device size.
filters: drop extra slash from sysfs path Sysfs filter was using '/sys//class/block' with double '//' inside. Remove this extra '/'. Also simplify code around and use loop to try those paths.
2013-11-21 20:50:12 +04:00
Drop extra unneeded '/' when scanning sysfs directory.
toollib: Avoid undefined ignore_vg parameter. Fix process_each_segment_in_pv to always set ret before calling ignore_vg().
2013-11-22 22:11:04 +04:00
Fix undef value if skipped clustered VG ignored for toollib PV seg. (2.02.103)

Version 2.02.104 - 13th November 2013
=====================================
pvscan: retry VG refresh before autoactivation if it fails There's a tiny race when suspending the device which is part of the refresh because when suspend ioctl is performed, the dm kernel driver executes (do_suspend and dm_suspend kernel fn): step 1: a check whether the dev is already suspended and if yes it returns success immediately as there's nothing to do step 2: it grabs the suspend lock step 3: another check whether the dev is already suspended and if found suspended, it exits with -EINVAL now The race can occur in between step 1 and step 2. To prevent premature autoactivation failure, we're using a simple retry logic here before we fail completely. For a complete solution, we need to fix the locking so there's no possibility for suspend calls to interleave each other to cause this kind of race. This is just a workaround. Remove it and replace it with proper locking once we have that in!
2013-11-12 13:55:34 +04:00
Workaround VG refresh race during autoactivation by retrying the refresh.
mirror: Handle failures in tmp mirror used when up-converting. Failures in the temporary mirror used when up-converting cause dmeventd to issue 'lvconvert --repair' on the sub-LV, <lv_name>_mimagetmp_?. The 'lvconvert' command refuses to deal with this sub-LV outright - it expects to be given the name of the top-level LV. So, just like we do with mirrored logs, we strip-off the portion of the name that is not the top-level LV and issue the command on the top-level LV instead.
2013-11-08 19:52:00 +04:00
Handle failures in temporary mirror used when adding images to mirrors.
activation: improve activation This patch fixes mostly cluster behavior but also updates non-cluster reaction where calls like 'lvchange -aln' lead to incorrect errors for some segment types. Fix the implicit activation rules where some segment types could be activated only in exclusive mode in cluster. lvm2 command was not preserver 'local' property and incorrectly converted local activations in to plain exclusive, so the local activation could have activate volumes exclusively, but remotely.
2013-11-01 13:31:31 +04:00
Fix and improve logic for implicitely exclusive activations.
activation: _lv_activate is ok when filtered. If the volume_list filters out volume from activation, it is still success result for this function. Change the error message back to verbose level. Detect if the volume is active localy before zeroing, so we report error a bit later for cases, where volume could not be activated because it doesn't pass through volume list (but user still could create volume when he disables zeroing)
2013-11-01 13:28:42 +04:00
Return success when LV cannot be activated because of volume_list filter.
locking: activate_lv_excl return correct error code Correct return code of activate_lv_excl(). Function is not supposed to return activation state of activated volume, but return code of the operation. Since i.e. when activation filter is allowing to activate volume on current system, it is still success even though no volume is activated.
2013-11-01 13:26:43 +04:00
Return proper error state for remote exclusive activation.
udev: properly trigger LVM scan for MD partitions MD can directly create partition devices without a need to run an extra kpartx or partprobe call. We need to react to this event in a different way as for bare MD devices - we need to handle the ADD event for KERNEL=="md[0-9]*p[0-9]*" kernel name and trigger the LVM scanning to update lvmetad to trigger autoactivation and so on... Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1023250
2013-10-30 17:02:38 +04:00
Fix missing lvmetad scan for PVs found on MD partitions.
WHATS_NEW: commit 9d06212 Other changes in previous commits 9d06212 and f1a42aa are changes in the code that was not yet released as part of upcoming v104.
2013-10-29 16:49:55 +04:00

WHATS_NEW: commit 4c0db84
2013-10-29 14:04:32 +04:00
Fix clvmd message verification to not reject REMOTE flag. (2.02.100)
gcc: fix comparing floating point warning Since we enabled some more gcc warnings - let's adapt for it and check for double equals with DBL_EPSILON. Current close_enough() is far from perfect for more details see i.e. here: http://randomascii.wordpress.com/2012/01/11/tricks-with-the-floating-point-format/ but fairly enough for lvm2 use-case.
2013-10-25 12:38:09 +04:00
Compare equality of double values with DBL_EPSILON predefined constant.
build: Use additional gcc warning flags.
2013-10-24 20:10:24 +04:00
Use additional gcc warning flags by default.
Mirror: Fix hangs and lock-ups caused by attempting label reads of mirrors There is a problem with the way mirrors have been designed to handle failures that is resulting in stuck LVM processes and hung I/O. When mirrors encounter a write failure, they block I/O and notify userspace to reconfigure the mirror to remove failed devices. This process is open to a couple races: 1) Any LVM process other than the one that is meant to deal with the mirror failure can attempt to read the mirror, fail, and block other LVM commands (including the repair command) from proceeding due to holding a lock on the volume group. 2) If there are multiple mirrors that suffer a failure in the same volume group, a repair can block while attempting to read the LVM label from one mirror while trying to repair the other. Mitigation of these races has been attempted by disallowing label reading of mirrors that are either suspended or are indicated as blocking by the kernel. While this has closed the window of opportunity for hitting the above problems considerably, it hasn't closed it completely. This is because it is still possible to start an LVM command, read the status of the mirror as healthy, and then perform the read for the label at the moment after a the failure is discovered by the kernel. I can see two solutions to this problem: 1) Allow users to configure whether mirrors can be candidates for LVM labels (i.e. whether PVs can be created on mirror LVs). If the user chooses to allow label scanning of mirror LVs, it will be at the expense of a possible hang in I/O or LVM processes. 2) Instrument a way to allow asynchronous label reading - allowing blocked label reads to be ignored while continuing to process the LVM command. This would action would allow LVM commands to continue even though they would have otherwise blocked trying to read a mirror. They can then release their lock and allow a repair command to commence. In the event of #2 above, the repair command already in progress can continue and repair the failed mirror. This patch brings solution #1. If solution #2 is developed later on, the configuration option created in #1 can be negated - allowing mirrors to be scanned for labels by default once again.
2013-10-23 04:14:33 +04:00
Add ignore_lvm_mirrors to config file to read/ignore labels on mirrors.
activation: flag temporary LVs internally Add LV_TEMPORARY flag for LVs with limited existence during command execution. Such LVs are temporary in way that they need to be activated, some action done and then removed immediately. Such LVs are just like any normal LV - the only difference is that they are removed during LVM command execution. This is also the case for LVs representing future pool metadata spare LVs which we need to initialize by using the usual LV before they are declared as pool metadata spare. We can optimize some other parts like udev to do a better job if it knows that the LV is temporary and any processing on it is just useless. This flag is orthogonal to LV_NOSCAN flag introduced recently as LV_NOSCAN flag is primarily used to mark an LV for the scanning to be avoided before the zeroing of the device happens. The LV_TEMPORARY flag makes a difference between a full-fledged LV visible in the system and the LV just used as a temporary overlay for some action that needs to be done on underlying PVs. For example: lvcreate --thinpool POOL --zero n -L 1G vg - first, the usual LV is created to do a clean up for pool metadata spare. The LV is activated, zeroed, deactivated. - between "activated" and "zeroed" stage, the LV_NOSCAN flag is used to avoid any scanning in udev - betwen "zeroed" and "deactivated" stage, we need to avoid the WATCH udev rule, but since the LV is just a usual LV, we can't make a difference. The LV_TEMPORARY internal LV flag helps here. If we create the LV with this flag, the DM_UDEV_DISABLE_DISK_RULES and DM_UDEV_DISABLE_OTHER_RULES flag are set (just like as it is with "invisible" and non-top-level LVs) - udev is directed to skip WATCH rule use. - if the LV_TEMPORARY flag was not used, there would normally be a WATCH event generated once the LV is closed after "zeroed" stage. This will make problems with immediated deactivation that follows.
2013-10-23 16:06:39 +04:00
Add internal flag for temporary LVs to properly direct udev to not interfere.
WHATS_NEW: typo
2013-10-22 18:37:02 +04:00
Fix endless loop in blkdeactivate <device>... if unable to umount/deactivate.
udev+systemd: refine lvm2-pvscan@.service to better track device existence When using ENV{SYSTEMD_WANTS}=lvm2-pvscan@... to instantiate a service for lvmetad scan when the new PV appears in the system, the service is started and executed. However, to track device removal, we need to bind it (the "BindsTo" systemd directive) to a certain .device systemd unit. In default systemd setup, the device is tracked by it's name and sysfs path (there's normally a sysfs path .device systemd unit for a device and then the device name .device unit as an alias for it). Neither of these two is useful for lvmetad update as we need to bind it to device's <major>:<minor> pair. The /dev/block/<major>:<minor> is the essential symlink under /dev that exists for each block device (created by default udev rules provided by udev directly). So let's use this as an alias for the device's .device unit as well by means of "ENV{SYSTEMD_ALIAS}" declaration within udev rules which systemd understands (this will create a new alias "dev-block-<major>:<minor>.device". Then we can easily bind the "dev-block-<major>:<minor>" device systemd unit with instantiated lvm2-pvscan@<major>:<minor>.service. So once the device is removed from the systemd, the lvm-pvscan@<major>:<minor>.service executes it's ExecStop action (which in turn notifies lvmetad about the device being gone). This completes the udev-systemd-lvmetad interaction then.
2013-10-22 16:03:53 +04:00
Add dev-block-<major>:<minor>.device systemd alias for complete PV tracking.
pvscan: use major:minor as short form of --major and --minor arg for pvscan --cache Before, pvscan recognized either: pvscan --cache --major <major> --minor <minor> or pvscan --cache <DevicePath> When the device is gone and we need to notify lvmetad about device removal, only --major/--minor works as we can't translate DevicePath into major/minor pair anymore. The device does not exist in the system and we don't keep DevicePath index in lvmetad cache to make the translation internally into original major/minor pair. It would be useless to keep this index just for this one exact case. There's nothing bad about using "--major <major> --minor <minor>", but it makes our life a bit harder when trying to make an interconnection with systemd units, mainly with instantiated services where only one and only one arg can be passed (which is encoded in the service name). This patch tries to make this easier by adding support for recognizing the "<major>:<minor>" as a shortcut for the longer form "--major <major> --minor <minor>". The rule here is simple: if the argument starts with "/", it's a DevicePath, otherwise it's a <major>:<minor> pair.
2013-10-22 15:52:18 +04:00
Use major:minor as short form of --major and --minor arg for pvscan --cache.
vgimportclone: remove 2>/dev/null from three lvm commands There is no point eating stderr for these commands. In fact the redirect causes confusion and hurts dubugging. Also reword an error message if the pvs command fails so as not be certain that a device is not a PV. Coupled with removing the stderr redirect this will improve the user experience in the face of errors.
2013-10-22 02:04:14 +04:00
Remove 2>/dev/null from three lvm commands executed by vgimportclone.
udev+systemd: make pvscan --cache -aay run as systemd background job from udev The new lvm2-pvscan@.service is responsible for on-demand execution of "pvscan --cache --activate ay" which causes lvmetad to be updated and LVM activation done if the VG is complete. Also, use udev-systemd mechanism to instantiate the job as the lvm2-pvscan@$devnode.service on each newly appeared PV in the system. This prevents the background job to be killed (that would happen if it was directly forked from udev rule - this behaviour is seen in recent versions of udev with the help of systemd that can track detached processes - the detached process would still be in the same cgroup). To enable this official udev-systemd protocol for instantiating background jobs, use new --enable-udev-systemd-background-jobs configure switch (it's disabled by default). This option is highly recommended wherever systemd is used!

Fix lvconvert swap of poolmetadata volume for active thin pool.
activation: check for open count with a timeout before removal/deactivation of an LV This patch reinstates the lv_info call to check for open count of the LV we're removing/deactivating - this was changed with commit 125712b some time ago and we relied on the ioctl retry logic deeper in the libdm while calling the exact 'remove' ioctl. However, there are still some situations in which it's still required to check for open count before we do any 'remove' actions - this mainly applies to LVs which consist of several sub LVs, like it is for virtual snapshot devices. The commit 1146691 fixed the issue with ordering of actions during virtual snapshot removal while the snapshot is still open. But the check for the open status of the snapshot is still prone to marking the snapshot as in use with an immediate exit even though this could be a temporary asynchronous open only, most notably because of udev and its WATCH udev rule with accompanying scans for the event which is asynchronous. The situation where this crops up most often is when we're closing the LV that was open for read-write and then calling lvremove immediately. This patch reinstates the original lv_info call for the open status of the LV in the lv_check_not_in_use fn that gets called before we do any LV removal/deactivation. In addition to original logic, this patch adds its own retry loop with a delay (25x0.2 seconds) besides the existing ioctl retry loop.
2013-10-15 14:44:42 +04:00
Check for open count with a timeout before removal/deactivation of an LV.
RAID: Report RAID images split with tracking as out-of-sync ("I"). Split image should have an out-of-sync attr ('I') - always. Even if the RAID LV has not been written to since the LV was split off, it is still not part of the group that makes up the RAID and is therefore "out-of-sync".
2013-10-14 19:48:44 +04:00
Report RAID images split with tracking as out-of-sync ("I").
snapshot: rework parsing of snapshot metadata Add better parsing code for snapshot metadata, which describe properly errors found for snapshot segment.
2013-10-09 16:50:51 +04:00
Improve parsing of snapshot lv segment.
snapshot: deactivate virtual snapshot first Since the virtual snapshot has no reason to stay alive once we detach related snapshot - deactivate whole thing in front of snapshot removal - otherwice the code would get tricky for support in cluster. The correct full solution would require to have transactions for libdm operations. Also enable to the check for snapshot being opened prior the origin deactivation, otherwise we could easily end with the origin being deactivate, but snapshot still kept active, desynchronizing locking state in cluster.
2013-10-12 01:53:28 +04:00
Add workaround for deactivation problem of opened virtual snapshot.
snapshot: disable merging for virtual snaps Merging into virtual origin is not supposed to work.

udev: add support for "NOSCAN" flag Recognize DM_SUBSYSTEM_UDEV_FLAG0 which for LVM is the "LVM_NOSCAN" flag that causes the scanning to be skipped (mainly blkid) and also directs all the foreign rules to be skipped as well. Important thing here is that the "watch" udev rules is still set as well as the /dev/disk/by-id content created (which does not require any scanning to be done). Also, the flag is dropped on any subsequent event and scanning done...
2013-10-08 15:33:28 +04:00
Recognize new flag to skip udev scanning in udev rules and act appropriately.
activation: add support for flagging an LV to skip udev scanning during activation A common scenario is during new LV creation when we need to wipe the newly created LV and avoid any udev scanning before this stage otherwise it could cause the device (the LV) to be claimed by some other subsystem for which there were stale metadata within LV data. This patch adds possibility to mark the LV we're just about to wipe with a flag that gets passed to udev via DM_COOKIE as a subsystem specific flag - DM_SUBSYSTEM_UDEV_FLAG0 (in this case the subsystem is "LVM") so LVM udev rules will take care of handling that.
2013-10-08 15:27:21 +04:00
Add support for flagging an LV to skip udev scanning during activation.
lvchange: improve discards when pool active error Existing message deemed misleading: Cannot change discards state for active pool volume https://bugzilla.redhat.com/show_bug.cgi?id=994315

RAID: Fix _sufficient_pes_free calculation for RAID lib/metadata/lv_manip.c:_sufficient_pes_free() was calculating the required space for RAID allocations incorrectly due to double accounting. This resulted in failure to allocate when available space was tight. When RAID data and metadata areas are allocated together, the total amount is stored in ah->new_extents and ah->alloc_and_split_meta is set. '_sufficient_pes_free' was adding the necessary metadata extents to ah->new_extents without ever checking ah->alloc_and_split_meta. This often led to double accounting of the metadata extents. This patch checks 'ah->alloc_and_split_meta' to perform proper calculations for RAID. This error is only present in the function that checks for the needed space, not in the functions that do the actual allocation.

RAID: Fix broken allocation policies for parity RAID types A previous commit (b6bfddcd0a830d0c9312bc3ab906cb3d1b7a6dd9) which was designed to prevent segfaults during lvextend when trying to extend striped logical volumes forgot to include calculations for RAID4/5/6 parity devices. This was causing the 'contiguous' and 'cling_by_tags' allocation policies to fail for RAID 4/5/6. The solution is to remember that while we can compare ah->area_count == prev_lvseg->area_count for non-RAID, we should compare (ah->area_count + ah->parity_count) == prev_lvseg->area_count for a general solution.
2013-09-25 06:32:10 +04:00
Fix contiguous & cling allocation policies for parity RAID. (2.02.100)

clvmd: Fix node up/down handing in corosync module The corosync cluster interface for clvmd did not correctly deal with node up/down events so that when a node was removed from the cluster clvmd would prevent remote operations from happening, as it thought the node was up but not running clvmd. This patch fixes that code by simplifying the case to node being up or down - which was the original intention and is supported by pacemaker and CPG in the higher layers.

systemd: run lvm2-activation-net.service after lvm2-activation.service The lvm2-activation-net.service was ordered only with respect to iscsi and fcoe service before. In addition to that, we also need ordering with respect to lvm2-activation.service to prevent parallel vgchange -aay runs which may cause some problems during activation. See also https://bugs.gentoo.org/show_bug.cgi?id=480066. With this patch, the ordering is firmly set to: lvm2-activation-early.service -> lvm2-activation.service -> lvm2-activation-net.service Thanks to Alexander Tsoy for the original patch (modified a bit here): https://www.redhat.com/archives/lvm-devel/2013-September/msg00049.html

RAID: Make RAID single-machine-exclusive capable in a cluster Creation, deletion, [de]activation, repair, conversion, scrubbing and changing operations are all now available for RAID LVs in a cluster - provided that they are activated exclusively. The code has been changed to ensure that no LV or sub-LV activation is attempted cluster-wide. This includes the often overlooked operations of activating metadata areas for the brief time it takes to clear them. Additionally, some 'resume_lv' operations were replaced with 'activate_lv_excl_local' when sub-LVs were promoted to top-level LVs for removal, clearing or extraction. This was necessary because it forces the appropriate renaming actions the occur via resume in the single-machine case, but won't happen in a cluster due to the necessity of acquiring a lock first. The *raid* tests have been updated to allow testing in a cluster. For the most part, this meant creating devices with '-aey' if they were to be converted to RAID. (RAID requires the converting LV to be EX because it is a condition of activation for the RAID LV in a cluster.)

Fix dmeventd unmonitoring of thin pools.
thin: fix resize of stacked thin pool volume When the pool is created from non-linear target the more complex rules have to be used and stacking needs to properly decode args for _tdata LV. Also proper allocation policies are being used according to those set in lvm2 metadata for data and metadata LVs. Also properly check for active pool and extra code to active it temporarily. With this fix it's now possible to use: lvcreate -L20 -m2 -n pool vg --alloc anywhere lvcreate -L10 -m2 -n poolm vg --alloc anywhere lvconvert --thinpool vg/pool --poolmetadata vg/poolm lvresize -L+10 vg/pool

2013-09-03 18:45:18 +04:00
Refresh existing VG before autoactivation (event retrigger/device reappeared).
tools: add -b/--background for pvscan --cache -aay Udev daemon has recently introduced a limit on the number of udev processes (there was no limit before). This causes a problem when calling pvscan --cache -aay in lvmetad udev rules which is supposed to activate the volumes. This activation is itself synced with udev and so it waits for the activation to complete before the pvscan finishes. The event processing can't continue until this pvscan call is finished. But if we're at the limit with the udev process count, we can't instatiate any more udev processes, all such events are queued and so we can't process the lvm activation event for which the pvscan is waiting. Then we're in a deadlock since the udev process with the pvscan --cache -aay call waits for the lvm activation udev processing to complete, but that will never happen as there's this limit hit with the number of udev processes. The process with pvscan --cache -aay actually times out eventually (3min or 30sec, depends on the version of udev). This patch makes it possible to run the pvscan --cache -aay in the background so the udev processing can continue and hence we can avoid the deadlock mentioned above.
2013-09-03 18:06:16 +04:00
Use pvscan -b in udev rules to avoid a deadlock on udev process count limit.
Add pvscan -b/--background for the command to be processed in the background.

systemd: lvm2-activation-generator: report only error otherwise be silent Do not print success status for lvm2-activation-generator: "LVM: Activation generator successfully completed." "LVM: Logical Volume autoactivation enabled." (if use_lvmetad=1) Though this information is quite useful during boot, it may be confusing for users if it happens anytime later and it actually happens if systemd reloads. This is usually on package update to update the systemd state and load any new units that are newly installed in the system. The systemd reload is global and so any existing generators are rerun at that moment too.
2013-08-22 10:14:11 +04:00
Make lvm2-activation-generator silent unless it's in error state.
filter-mpath: remove superfluous error message about mpath major not equal to dm major This is a regression caused by commit 3bd90488545a4ad5374b4e0f1daba6cf16ae6ae8. The error message added with that commit "mpath major %d is not dm major %d" is superfluous. When scanning for mpath components, we're looking for a parent device. But this parent device is not necessarily an mpath device (so the dm device) if it exists - it can be any other device layered on top (e.g. an MD RAID device).
2013-08-21 16:07:01 +04:00
Remove "mpath major is not dm major" msg for mpath component scan (2.02.94).
cmirrord: Prevent secondary checkpoints from corrupting bitmaps The bug addressed by this patch manifested itself during testing by showing a mirror that never became 'in-sync' after creation. The bug is isolated to distributions that do not have support for openAIS checkpointing (i.e. > RHEL6, > F16). When a node joins a group that is managing a mirror log, the other machines in the group send it a checkpoint representing the current state of the bitmap. More than one machine can send a checkpoint, but only the initial one should be imported. Once the bitmap state has been imported from the initial checkpoint, operations (such as resync, mark, and clear operations) can begin. When subsequent checkpoints are allowed to be imported, it has the effect of erasing all the log operations between the initial checkpoint and the ones that follow. When cmirrord was updated to handle the absence of openAIS checkpointing (commit 62e38da133d9801cdf36b0f2aaec615ce14b9000), the new import_checkpoint() function failed to honor the 'no_read' parameter. This parameter was designed to avoid reading all but the initial checkpoint. Honoring this parameter has solved the issue of corrupting bitmap data with secondary checkpoints.
2013-08-20 22:21:09 +04:00
Prevent cluster mirror logs from being corrupted by redundant checkpoints.
udev: fix lvmetad rules to not ignore loop device configuration If loop device is first configured on systems where /dev/loop-control is used to dynamically create the loop device itself, there's an ADD+CHANGE even generated. But next time the existing /dev/loop[0-9]* is reused, there's only a CHANGE event since the device representing it is already present in kernel (so no ADD event in this case). We can't ignore this CHANGE event for loop devices! This is a regression caused by 756bcabbfe297688ba240a880bc2b55265ad33f0. We already had a similar problem with MD devices which was fixed by 2ac217d408470dcecb69b83d9cbf7a254747fa5b (but that one was only an intra-release fix).

Fix ignored lvmetad update on loop device configuration (2.02.99).
systemd: use LVM_PATH instead of hardcoded value in activation generator
2013-08-15 11:57:30 +04:00
Use LVM_PATH instead of hardcoded value in lvm2 activation systemd generator.
WHATS_NEW: for 0da72743ca46ae9f8185cd12d5c78b3c2b801872
2013-08-14 12:18:02 +04:00
Fix vgck to notice on-disk corruption even if lvmetad is used.
filters: check for mpath before opening devs Split out the partitioned device filter that needs to open the device and move the multipath filter in front of it. When a device is multipathed, sending I/O to the underlying paths may cause problems, the most obvious being I/O errors visible to lvm if a path is down. Revert the incorrect <backtrace> messages added when a device doesn't pass a filter. Log each filter initialisation to show sequence. Avoid duplicate 'Using $device' debug messages.
2013-08-14 02:26:58 +04:00
Move mpath device filter before partitioned filter (which opens devices).
Split partitioned filter out of lvm_type filter.
Merge filter*.h into a single filter.h.
vgchange: require confirmation with -c and no VGs Too many people have been running 'vgchange -cy' by mistake so add a confirmation prompt. Use --yes to bypass this.
2013-08-13 21:20:11 +04:00
Require confirmation for vgchange -c when no VGs listed explicitly.
WHATS_NEW: be more precise
2013-08-13 20:25:54 +04:00
Also skip /var and /var/log by default in blkdeactivate when unmounting.
blkdeactivate: add support for bind mounts Recent version of util-linux/umount (v2.23+) provides umount --all-targets that can unmount all the mount targets of the same device (the bind mounts). Use this if available when calling the umount blkdeactivate. Otherwise, for older versions of util-linux, use findmnt (that is also a part of the util-linux) to iterate over all mount targets of the same device - this is the manual way.
2013-08-13 19:26:36 +04:00
Add support for bind mounts in blkdeactivate.
blkdeactivate: change the way blkdeactivate reports status The blkdeactivate now suppresses error messages from external tools that are called. Instead, only a summary message "done" or "skipped" is issued by blkdeactivate as any error in calling the external tool (e.g. unmounting or deactivating a device) causes the device to be skipped and the blkdeactivate continues with the next device in the tree. Add new -e/--errors switch to display any error messages from external tools. Also, suppress any output given by the external tools and add new -v/--verbose switch to display it including the verbose output of the tools called (this will enable error reporting as well). Also add blkdeactivate -vv for even more debug (the script's debug).
2013-08-13 19:17:25 +04:00
Add blkdeactivate -v/--verbose for debug output from external tools used.
Add blkdeactivate -e/--errors for error messages from external tools used.
Suppress messages from external tools called in blkdeactivate by default.

Version 2.02.100 - 13th August 2013
===================================
Mirror: Fix inability to remove VG's cluster flag if it contains a mirror According to bug 995193, if a volume group 1) contains a mirror 2) is clustered 3) 'locking_type' = 0 is used then it is not possible to remove the 'c'luster flag from the VG. This is due to the way _lv_is_active behaves. We shouldn't allow the cluster flag to be flipped unless the mirrors in the cluster are not active. This is because different kernel modules are used depending on whether a mirror is cluster or not. When we attempt to see if the mirror is active, we first check locally. If it is not, then we attempt to check for remotely active instances if the VG is clustered. Since the no_lock locking type is LCK_CLUSTERED, but does not implement 'query_resource', remote_lock_held will always return an error in this case. An error from remove_lock_held is treated as though the lock _is_ held (i.e. the LV is active remotely). This blocks the cluster flag from changing. The solution is to implement 'query_resource' for the no_lock type. It will report a message and return 1. This will allow _lv_is_active to function properly. The LV would be considered not active remotely and the VG can change its flag.
2013-08-12 22:56:47 +04:00
Fix inability to remove a VG's cluster flag if it contains a mirror.
logging: tidy log_sys_error when string empty
2013-08-12 21:40:41 +04:00
Suppress arg: prefix in log_sys_error macro when arg is empty string.
RAID: Fix bug making lvchange unable to change recovery rate for RAID 1) Since the min|maxrecoveryrate args are size_kb_ARGs and they are recorded (and sent to the kernel) in terms of kB/sec/disk, we must back out the factor multiple done by size_kb_arg. This is already performed by 'lvcreate' for these arguments. 2) Allow all RAID types, not just RAID1, to change these values. 3) Add min|maxrecoveryrate_ARG to the list of 'update_partial_unsafe' commands so that lvchange will not complain about needing at least one of a certain set of arguments and failing. 4) Add tests that check that these values can be set via lvchange and lvcreate and that 'lvs' reports back the proper results.
2013-08-10 02:09:47 +04:00
Fix bug making lvchange unable to change recovery rate for RAID.
WHATSNEW: typo
2013-08-10 02:17:53 +04:00
Prohibit conversion of thin pool to external origin.
workaround: gcc v4.8 on 32 bit param. passing bug when -02 opimization used gcc -O2 v4.8 on 32 bit architecture is causing a bug in parameter passing. It does not happen with -01 nor -O0. The problematic part of the code was strlen use in config.c in the config_def_check fn and the call for _config_def_check_tree in it: <snip> rplen = strlen(rp); if (!_config_def_check_tree(handle, vp, vp + strlen(vp), rp, rp + rplen, CFG_PATH_MAX_LEN - rplen, cn, cmd->cft_def_hash)) ... </snip> If compiled with -O0 (correct): Breakpoint 1, config_def_check (cmd=0x819b050, handle=0x81a04f8) at config/config.c:775 (gdb) p vp $1 = 0x8189ee0 <_cfg_path> "config" (gdb) p strlen(vp) $2 = 6 (gdb) _config_def_check_tree (handle=0x81a04f8, vp=0x8189ee0 <_cfg_path> "config", pvp=0x8189ee6 <_cfg_path+6> "", rp=0xbfffe1e8 "config", prp=0xbfffe1ee "", buf_size=58, root=0x81a2568, ht=0x81a65 48) at config/config.c:680 (gdb) p vp $4 = 0x8189ee0 <_cfg_path> "config" (gdb) p pvp $5 = 0x8189ee6 <_cfg_path+6> "" If compiled with -O2 (incorrect): Breakpoint 1, config_def_check (cmd=cmd@entry=0x8183050, handle=0x81884f8) at config/config.c:775 (gdb) p vp $1 = 0x8172fc0 <_cfg_path> "config" (gdb) p strlen(vp) $2 = 6 (gdb) p vp + strlen(vp) $3 = 0x8172fc6 <_cfg_path+6> "" (gdb) _config_def_check_tree (handle=handle@entry=0x81884f8, pvp=0x8172fc7 <_cfg_path+7> "host_list", rp=rp@entry=0xbffff190 "config", prp=prp@entry=0xbffff196 "", buf_size=buf_size@entry=58, ht=0x 818e548, root=0x818a568, vp=0x8172fc0 <_cfg_path> "config") at config/config.c:674 (gdb) p pvp $4 = 0x8172fc7 <_cfg_path+7> "host_list" The difference is in passing the "pvp" arg for _config_def_check_tree. While in the correct case, the value of _cfg_path+6 is passed (the result of vp + strlen(vp) - see the snippet of the code above), in the incorrect case, this value is increased by 1 to _cfg_path+7, hence totally malforming the string that is being processed. This ends up with incorrect validation check and incorrect warning messages are issued like: "Configuration setting "config/checks" has invalid type. Found integer, expected section." To workaround this issue, remove the "static" qualifier from the "static char _cfg_path[CFG_PATH_MAX_LEN]". This causes the optimalizer to be less aggressive (also shuffling the arg list for _config_def_check_tree call helps).
2013-08-09 15:06:17 +04:00
Workaround gcc v4.8 -O2 bug causing failures if config/checks=1 (32bit arch).

When creating PV on existing LV don't forbid reserved LV names on LVs below.
Split out device_is_suspended_or_blocking from device_is_usable.
Mirror/RAID1: When up|down-converting default to segtype of current LV If there is no RAID support in the kernel but the default mirror segtype is "raid1", converting legacy mirrors can be problematic. For example, changing the log type or converting a mirror to a linear LV does not require the RAID modules to be present. However, because lp->segtype is set to be RAID1 by the configuration file, the command fails. We should only be setting lp->segtype when converting mirrors if it is going to change (e.g. to linear or between mirror types).
2013-08-08 01:01:45 +04:00
When converting mirrors, default segtype should be the same unless specified.
RAID: Make "raid1" the default mirror segment type
2013-08-06 23:13:55 +04:00

WHATS_NEW: previous commit
2013-08-06 16:03:43 +04:00
Fix metadata area offset/size overflow if it's >= 4g and while using lvmetad.
thin: apply VG profile if creating a new thin pool When creating a new thin pool and there's no profile requested via "lvcreate --profile ...", inherit any VG profile if it's attached. Currently this applies to these settings: allocation/thin_pool_chunk_size allocation/thin_pool_discards allocation/thin_pool_zero
2013-08-06 13:42:40 +04:00
Inherit and apply any profile attached to a VG if creating new thin pool.
thin: initial --repair support for pools Initial basic support for repair. It currently takes pool metadata spare volume, which is used for recovery. New spare is created if the volume is successfuly repaired. After the operation the previous _tmeta volume is moved into _tmeta%d volume and if everything is ok, this volume could be removed. New _tmeta needs to be pvmoved to proper place and also converted to i.e. mirror if it should be mirrored. Later version will try to automate some steps here.
2013-07-24 17:25:34 +04:00
Add initial support thin pool lvconvert --repair.
thin: add thin_repair and thin_dump options Add new configure lvm.conf options for binaries thin_repair and thin_dump. Those are part of device-mapper-persistent-data package and will be used for recovery of thin_pool.
2013-07-31 16:38:10 +04:00
Add --with-thin-repair and --with-thin-dump configure options.
Add lvm.conf thin_repair/dump_executable and thin_repair_options.
thin: metadata resize needs 1.9 version Version 1.8 is not yet fully usable for metadata resize.
2013-07-25 16:35:08 +04:00
Require 1.9 thin pool target version for online thin pool metadata resize.
alloc: fix lvextend when stripe number varies The PREFERRED allocation mechanism requires the number of areas in the previous LV segment to match the number in the new segment being allocated. If they do not match, the code may crash. E.g. https://bugzilla.redhat.com/989347 Introduce A_AREA_COUNT_MATCHES and when not set avoid referring to the previous segment with the contiguous and cling policies.
2013-07-29 22:35:45 +04:00
Ignore previous LV seg with alloc contiguous & cling when num stripes varies.
filters: fix segfault on incorrect global_filter When using a global_filter and if this filter is incorrectly specified, we ended up with a segfault: raw/~ $ pvs Invalid filter pattern "r|/dev/sda". Segmentation fault (core dumped) In the example above a closing '|' character is missing at the end of the regex. The segfault itself was caused by trying to destroy the same filter twice in _init_filters fn within the error path (the "bad" goto target): bad: if (f3) f3->destroy(f3); if (f4) f4->destroy(f4); Where f3 is the composite filter (sysfs + regex + type + md + mpath filter) and f4 is the persistent filter which encompasses this composite filter within persistent filter's 'real' field in 'struct pfilter'. So in the end, we need to destroy the persistent filter only as this will also destroy any 'real' filter attached to it.
2013-07-26 14:47:28 +04:00
Fix segfault if devices/global_filter is not specified correctly.

Version 2.02.99 - 24th July 2013
================================
thin: not zeroing for non-zeroed thin pool snaps Do not zero initial 4KB of thin snapshot volume for thin pool with disabled zeroing.
2013-07-24 03:11:15 +04:00
Do not zero init 4KB of thin snapshot for non-zeroing thin pool (2.02.94).
lvconvert: add more checks for lvconvert --type The --type mirror requires -m/--mirrrors: lvconvert --type mirror vg/lvol0 --type mirror requires -m/--mirrors Run `lvconvert --help' for more information. The --type raid* is allowed (the checks already existed): lvconvert --type raid10 vg/lvol0 Converting the segment type for vg/lvol0 from linear to raid10 is not yet supported. The --type snapshot is a synonym to -s/--snapshot: lvconvert -s vg/lvol0 vg/lvol1 Logical volume lvol1 converted to snapshot. lvconvert --type snapshot vg/lvol0 vg/lvol1 Logical volume lvol1 converted to snapshot. All the other segment types are not supported, e.g.: lvconvert --type zero vg/lvol0 Conversion using --type zero is not supported. Run `lvconvert --help' for more information.
2013-07-23 19:04:43 +04:00
Issue an error msg if lvconvert --type used incorrectly with other options.
systemd: lvm2-activation-generator: use LOG_DEBUG/ERR severity for kmsg
2013-07-22 16:04:12 +04:00
Use LOG_DEBUG/ERR msg severity instead default for lvm2-activation-generator.
cmdline: support ARG_GROUPABLE in merge_synonym
2013-07-19 23:37:43 +04:00
Support ARG_GROUPABLE with merge_synonym (for --raidwritemostly).
RAID: Fix segfault when reporting raid_syncaction field on older kernel The status printed for dm-raid targets on older kernels does not include the syncaction field. This is handled by dev_manager_raid_status() just fine by populating the raid status structure with NULL for that field. However, lv_raid_sync_action() does not properly handle that field being NULL. So, check for it and return 0 if it is NULL.
2013-07-19 19:01:48 +04:00
Fix segfault when reporting raid_syncaction for older kernels.
cleanup: comments and a message
2013-07-25 01:10:37 +04:00
Add LV report fields: raid_mismatch_count/raid_sync_action/raid_write_behind.
reporting: tidy recent new fields Add underscores and prefixes to recently-added fields. (Might add more alias functionality in future.)
2013-07-19 04:30:02 +04:00
Add LV reporting fields raid_min_recovery_rate, raid_max_recovery_rate.
Add sync_percent as alias for copy_percent LV reporting field.
Add lv_ prefix to modules reporting field.
display: fix units for sizes <1k
2013-07-18 20:55:58 +04:00
Use units B or b (never E) with no decimal places when displaying sizes < 1k.
thin: add pool metadata spare lv support Add support for pool's metadata spare volume.
2013-07-05 19:10:47 +04:00
Add support for poolmetadataspare LV, that will be used for pool recovery.
thin: improve pool creation activation order Pool creation involves clearing of metadata device which triggers udev watch rule we cannot udev synchronize with in current code. This metadata devices needs to be activated localy, so in cluster mode deactivation and reactivation is always needed. However for non-clustered mode we may reload table via suspend/resume path which avoids collision with udev watch rule which was occasionaly triggering retry deactivation loop. Code has been also split into 2 separate code paths for thin pools and thin volumes which improved readability of the code as well. Deactivation has been moved out of extend_pool() and decision is now in _lv_create_an_lv() which knows the change mode.
2013-07-18 18:44:39 +04:00
Improve activation order when creating thin pools in non-clustered VG.
thin: for thin volumes properly list modules thin volume needs thin-pool and thin kernel modules so print them both for lvs -o+modules
2013-07-18 18:06:26 +04:00
List thin-pool and thin modules for thin volumes.
thin: fix error path in creation path Remove some calls to revert_new_lv when no LV has been created/commited so far. When the pool update failed - then only revert is needed.
2013-07-17 17:26:41 +04:00
Correct thin creation error paths.
snapshot: local activation for clear COW device To clear snapshot cow device in cluster enforce local activation here.
2013-07-18 18:20:48 +04:00
Use local activation for clearing snapshot COW device.
systemd: generator: add lvm2-activation-net.service The new lvm2-activation-net.service activates LVM volumes after network-attached devices are set up (iSCSI and FCoE) if lvmetad is disabled and hence the autoactivation is not used.
2013-07-17 18:21:18 +04:00
Add lvm2-activation-net systemd unit to activate LVs on net-attached storage.
dev_manager: lower memory usage Created dlid for test is not needed afterward, so lower a memory usage of this call is repeatedly used for building some large tree. TODO: create function to use given buffer on stack as much cheaper.
2013-07-14 17:08:26 +04:00
Release memory allocated with _cached_info().
thin: add sub volumes as whole volumes Do not use origin_only when add log_lv and metadata as a subvolume. The stacked volume needs to access whole volume in this case.
2013-07-15 15:39:53 +04:00
Add whole log_lv and metadata_lv sub volumes when creating partial tree.
thin: check and use layered origin lv Code needs to check if the layer origin device is suspended, It's valid to create thinvolume snapshot of thinvolume which is also used as an old-style snapshot. In this case we need to check -real is suspended. When adding origin_only - add only layer thin volume. (in case it's also old-snapshot add only -real device)
2013-07-15 13:47:10 +04:00
Properly use snapshot layer for origin which is also thin volume.
thin: write back when command successfully finished Remove backup() call from update_pool_lv() as it's been there duplicated and preperly order backup() call after lvresize, so there is just one such call.
2013-07-15 13:39:03 +04:00
Avoid generating metadata backup when calling update_pool_lv().
thin: send messages to active pool If the thin pool is known to be active, messages can be passed to the pool even when the created thin volume is not going to be activated. So we do not need to stack large list of message and validate and catch creation errors earlier in this case. Replace the test for valid activation combination with simpler list of deactivation combinations.
2013-07-15 13:27:57 +04:00
Send thin messages also for active thin pool and inactive thin volume.
WHATS_NEW: support for LV activation skip flag
2013-07-12 21:52:32 +04:00
Add activation/auto_set_activation_skip to control activation skip flagging.
Add 's(k)ip activation' bit to lvs -o lv_attr to indicate skip flag attached.
Add --ignoreactivationskip to lvcreate/vgchange/lvchange to ignore skip flag.
Add --setactivationskip to lvcreate/lvchange to set activation skip flag.
Automatically flag thin snapshots to be skipped during activation.
Add support for persistent flagging of LVs to be skipped during activation.
dumpconfig: add --type profilable The --type profilable shows all config settings that are customizable by profiles: raw/~ $ lvm dumpconfig --type profilable allocation { thin_pool_zero=1 thin_pool_discards="passdown" thin_pool_chunk_size=64 } activation { thin_pool_autoextend_threshold=100 thin_pool_autoextend_percent=20 }
2013-07-09 11:57:46 +04:00
Add --type profilable to lvm dumpconfig to show profilable config settings.
dumpconfig: add --mergedconfig option Normally, the lvm dumpconfig processes only the configuration tree that is at the top of the cascade. Considering the cascade is: CONFIG_STRING -> CONFIG_PROFILE -> CONFIG_MERGED_FILES/CONFIG_FILE ...then: (dumpconfig of lvm.conf only) raw/~ $ lvm dumpconfig allocation allocation { maximise_cling=1 mirror_logs_require_separate_pvs=0 thin_pool_metadata_require_separate_pvs=0 thin_pool_chunk_size=64 } (dumpconfig of selected profile configuration only) raw/~ $ lvm dumpconfig --profile test allocation allocation { thin_pool_chunk_size=8 thin_pool_discards="passdown" thin_pool_zero=1 } (dumpconfig of given --config configuration only) raw/~ $ lvm dumpconfig --config 'allocation{thin_pool_chunk_size=16}' allocation allocation { thin_pool_chunk_size=16 } The --mergedconfig option causes the configuration cascade to be merged before processing it with dumpconfig: (dumpconfig of merged selected profile and lvm.conf) raw/~ $ lvm dumpconfig --profile test allocation --mergedconfig allocation { maximise_cling=1 thin_pool_zero=1 thin_pool_discards="passdown" mirror_logs_require_separate_pvs=0 thin_pool_metadata_require_separate_pvs=0 thin_pool_chunk_size=8 } (dumpconfig merged given --config and selected profile and lvm.conf) raw/~ $ lvm dumpconfig --profile test --config 'allocation{thin_pool_chunk_size=16}' allocation --mergedconfig allocation { maximise_cling=1 thin_pool_zero=1 thin_pool_discards="passdown" mirror_logs_require_separate_pvs=0 thin_pool_metadata_require_separate_pvs=0 thin_pool_chunk_size=16 } Hence with the --mergedconfig, we are able to see the configuration that is actually used when processing any LVM command while using any combination of --config/--profile options together with lvm.conf file.
2013-07-08 17:34:27 +04:00
Add --mergedconfig to lvm dumpconfig for merged --config/--profile/lvm.conf.
locking: unlock memory on error path Unlock memory and unblock signals on error path.
2013-07-06 12:58:56 +04:00
Relase memory and unblock signals in lock_vol error path.
lvresize: separate validation from action Start separating the validation from the action in the basic lvresize code moved to the library. Remove incorrect use of command line error codes from lvresize library functions. Move errors.h to tools directory to reinforce this, exporting public versions of the error codes in lvm2cmd.h for dmeventd plugins to use.
2013-07-06 06:28:21 +04:00
Define LVM2_* command errors in lvm2cmd.h and use in dmeventd plugins.
Move errors.h to tools dir.
man: document profile config and related options Document following items: configuration cascade (man lvm.conf) --profile ProfileName (man lvm) --detachprofile (man vgchange/lvchange) -o vg_profile/lv_profile (man vgs/lvs) Also document --config a bit so we can see where it fits in the configuration cascade - will be documented more in following commit...
2013-07-03 18:45:27 +04:00
Add man page entries for profile configuration and related options.
sigint: improve logic on for sigint reaction Fix and improve handling on sigint. Always check for signal presence *before* calling of command, so it will not call the command when break was hit. If the command has been finished succesfully there is no problem to mark the command ok and not report interrupt at all. Fix cuple related stack; reports and assignments.
2013-07-01 18:30:12 +04:00
Improve error loging when user tries to interrupt commands.
lvconvert: Rename _swap_lv to _swap_lv_identifiers and move to allow an additional user
2013-07-03 01:02:25 +04:00
Rename _swap_lv to _swap_lv_identifiers and move to allow an additional user.
snapshot: Rename snapshot segment returning methods from find_*_cow to find_*_snapshot find_cow -> find_snapshot, find_merging_cow -> find_merging_snapshot. Will thin snapshot code to reuse these methods without confusion.
2013-07-03 00:26:03 +04:00

Add default.profile configuration profile and install it on make install.
Create a new 'conf' subdir for configuration files including profiles.
Make selected thinp settings customizable by a profile.
Support changing VG/LV profiles: vgchange/lvchange --profile/--detachprofile.
Support storing profile name in metadata for both VGs and LVs.
Add new --profile command line arg to select a configuration profile for use.
WHATS_NEW: config/profile_dir
2013-07-02 17:57:46 +04:00
Add config/profile_dir to set working directory to load profiles from.
WHATS_NEW: configuration profile support
2013-07-02 17:51:21 +04:00
Add configure --with-default-profile-subdir to select dir to keep profiles in.
Add support for configuration profiles.
Introduce config_source wrapper for identification of configuration sources.
archiver: do not archive vg more then once Do not keep multiple archives for the executed command. Reuse the ALLOCATABLE_PV from pv status for ARCHIVED_VG vg status. Mark VG with the bit with the first archivation.
2013-06-30 20:01:19 +04:00
Avoid creation of multiple archives for one command.
RAID/MIRROR: Honor mirror_segtype_default when upconverting linear LVs If the user would upconvert a linear LV to a mirror without specifying the segment type ("--type mirror" vs "--type raid1"), the "mirror" segment type would be chosen without consulting the 'default_mirror_segtype' setting in lvm.conf. This is now used as the basis for determining which should be used if left unspecified.
2013-06-20 02:50:10 +04:00
Use mirror_segtype_default if type not specified for linear->mirror upconvert.
lvmetad: fix compare function Check for enough space in preallocated buffer. Fixes problem, when lvm code started to suddenly allocate too big memory chunks. TODO: lvmetad protocol should announce needed size ahead, so if metadata have 1MB we are not reallocating memory...
2013-06-18 23:58:13 +04:00
Fix use of too big chunks of memory when communication with lvmetad.
vgcfgrestore: fix crash on restore of wrong vgname When vgname has not existed in metadata, it has crashed on double free in format_instance destroy() - since VG was created, used FID and was released - which also released FID, so further use was accessing bad memory. Fix it for this code path before release_vg() so FID will exists when _vg_read_file_name() returns NULL.
2013-06-18 23:50:29 +04:00
Fix vgcfgrestore crash when specified incorrect vg name.
man: refine lvm.conf and man page documentation for autoactivation feature
2013-06-14 11:36:56 +04:00
Refine lvm.conf and man page documentation for autoactivation feature.
thin: vgsplit support for thins Support vgsplit for VGs with thin pools and thin volumes. In case the thin data and thin metadata volumes are moved to a new VG, move there also all related thin volumes and check that external origins are also present in this new VG.
2013-06-13 14:05:53 +04:00
Add support for thin volumes in vgsplit.
filter-mpath: detect partitions of mpath components We use mpath filtering (enabled by devices/multipath_component_detection=1 lvm.conf setting) to avoid a situation in which we could end up with duplicate PVs found. We need to filter out the mpath components and use only the top-level multipath mapping instead for PV scans. However, if the there are partitions on multipath components, we need to filter out these partitions. This patch fixes it so those partitions found on multipath components are filtered as well. For example, let's consider following configuration: The sda and sdb are mpath components, sda1 and sdb1 the partitions on these components, mpath-test the mpath mapping and mpath-test1 the partition mapping - created automatically by kpartx right after mpath-test creation. The PV resides on top. (LVM PV) | mpath-test1 | mpath-test | sda1 ---------- sdb1 \ | |/ sda sdb E.g. for sda1 and sdb1, the code will detect this and it skips the partition that belongs to the multipath component: <snippet from the log> #filters/filter-mpath.c:156 /dev/sda1: Device is a partition, using primary device /dev/sda for mpath component detection 130 #ioctl/libdm-iface.c:1724 dm status (253:2) OF[16384](*1) 131 #filters/filter-mpath.c:196 /dev/sda1: Skipping mpath component device </snippet from the log> Othewise, we'd see the same PV label on sda1/sdb1 and mpath-test1 at the same time ending up with "Duplicate PV found...".
2013-06-12 14:20:10 +04:00
Also filter partitions on mpath components if multipath_component_detection=1.
thin: lvresize supports pool metadata resize Add support for lvresize of thin pool metadata device. lvresize --poolmetadatasize +20 vgname/thinpool_lv or lvresize -L +20 vgname/thinpool_lv_tmeta Where the second one allows all the args for resize (striping...) and the first option resizes accoding to the last metadata lv segment.
2013-06-11 15:45:49 +04:00
Add lvresize support for online thin pool metadata volume resize.
thin: add helper functions Add find_pool_lv() and pool_can_resize_metadata().
2013-06-11 14:32:01 +04:00
Add helper functions find_pool_lv() and pool_can_resize_metadata().
thin: detect online metadata resize support
2013-06-11 14:31:01 +04:00
Add detection for thin pool metadata resize kernel support.
thin: report 'e' metadata type with higher priority Giving volume type information about being 'metadata' type of volume has higher priority then i.e. 'mirror' or 'thin' flag - for those type we have 'target attr' (7th. field).
2013-06-05 15:46:38 +04:00
Report lvs volume type 'e' with higher priority.
thin: report o as volume type for external origin Reuse 'o' attr for lvs report also for external origin.
2013-06-05 15:45:31 +04:00
Report lvs volume type 'o' also for external origin volumes.
thin: report t for thin pool and volume Do not mark internal device _tdata and _tmeta as having target type 't'. They have the target type on their own (i.e. mirror, raid).
2013-06-05 15:44:10 +04:00
Report lvs target type 't' only for thin pools and thin volumes.
snapshots: check for active state Fix testing if the snapshot could be resized and use lv_is_active() to get correct answer in cluster.
2013-06-11 15:07:13 +04:00
Fix test for active snapshot in cluster before resizing it.
cleanup: comments and a message
2013-07-25 01:10:37 +04:00
Allow local activation to receive a locally-supplied LV struct.
Add vg->vg_ondisk / lv_ondisk() holding committed metadata.
filters: dump filter returns error code Add int return value from dump() function. Report stack for error case. Update composable filter.
2013-06-03 01:27:34 +04:00
Report backtrace from dump filter error path.
lvmetad: no use of persistent filter with lvmetad
2013-05-27 03:55:14 +04:00
Do not use persistent filter with lvmetad.
filters: update composable filter Last commit made dump filter only partially composable. Add remaining functionality and also support composable wipe, which is needed, when i.e. vgscan needs to remove cache. (in release fix)
2013-06-02 23:59:57 +04:00
Composable persistent filter functionality for global filter.
vgimportclone: override global_filter in lvm.conf The global filter in system's lvm.conf may conflict with the custom filter we set up in vgimportclone (they can easily fail to intersect). Since we explicitly avoid talking to lvmetad in vgimportclone, it is safe and reasonable to do so.
2013-04-29 00:38:22 +04:00
Override system's global_filter settings for vgimportclone.
lvresize: check for max snapshot size As for lvcreate, lvresize also doesn't need to grow bigger then needed.
2013-05-29 23:23:02 +04:00
Detect maximum usable size for snapshot for lvresize.
lvcreate: reduce too large cow Detect maximum usable size of snapshot COW device, and do not waste more space for such LV then needed.
2013-05-29 23:43:46 +04:00
Creation of snapshot takes at most 100% origin coverage.
snapshot: add cow_max_extents Add more precise calculation of the maximum usable snapshot size. Using only percentage fails for small size of snapshot and extents.
2013-05-29 14:44:54 +04:00
Add cow_max_extents() to calc extents for 100% origin coverage.
snapshot: require 3 chunks for creation There is no point in creation of 2chunks snapshot, since the snapshot is invalidated immeditelly with the first write as there is no free chunk for COW blocks (2 chunks are used by the snap header and the 1st. metadata chunk). Enhance error message about the lowest usable size.
2013-05-29 14:39:33 +04:00
For creation of snapshot require size for at least 3 chunks.
snapshot: fix resize of 100% full cow When the COW area is using all the available space (100%) it can be still a valid snapshot which may need a resize. So support it.
2013-05-29 23:17:15 +04:00
Fix lvresize --use-policies of VALID but 100% full snapshot.
args: do not accept >=16EiB sizes Instead of seeing wierd overflows inside the lvm code, giving false error messages, kill the user experiment in the begining. Who needs to use more then 16EiB with lvm2 and 64bit anyway...
2013-05-29 16:50:21 +04:00
Do not accept size parameters bigger then 16EiB.
fid: fix reset of PV fid Avoid hitting memory corruption (double free) in code path, where PV FID has been already destroyed and the released pointer was left in PV structure and could have been tried to be released from there 2nd. time with final context destruction.
2013-05-29 14:42:09 +04:00
Fix release of PV's fid in free_pv_fid().
snapshot: skip monitor for large cows If snapshot cow device is already big enough to cover whole origin, do not monitor it.
2013-05-27 12:20:06 +04:00
Skip monitoring of snapshots that are already bigger then origin.
snapshot: add lv_is_cow_covering_origin Add function to check is size of cow is already big enough to cover whole origin.
2013-05-27 12:18:20 +04:00
Add lv_is_cow_covering_origin() to check if cow covers origin size.
snapshot: use dm_get_status_snapshot() Replace code with libdm call to dm_get_status_snapshot().
2013-05-26 19:04:14 +04:00
Use libdm dm_get_status_snapshot() to parse snapshot status.
vgchange: check for mounted fs Check for mounted fs also for vgchange command, not just lvchange. NOTE: Code is using lv_info() just like lvs_in_vg_opened(). It should be probably converted into lv_is_active_locally().
2012-03-09 02:43:28 +04:00
Add detection of mounted fs also for vgchange deactivation.
Clean-up: Replace 'lv_is_active' with more correct/specific variants There are places where 'lv_is_active' was being used where it was more correct to use 'lv_is_active_locally'. For example, when checking for the existance of a kernel instance before asking for its status. Most of the time these would work correctly. (RAID is only allowed on non-clustered VGs at the moment, which means that 'lv_is_active' and 'lv_is_active_locally' would give the same result.) However, it is more correct to use the proper variant and it helps with future scenarios where targets might be allowed exclusively (or clustered) in a cluster VG.
2013-05-16 19:36:56 +04:00
Replace 'lv_is_active' with more correct/specific variants (e.g. *_locally).
WHATS_NEW: bad day
2013-05-16 13:02:18 +04:00
Refuse to init a snapshot merge in lvconvert if there's no kernel support.
make: fix exported symbols regex for non-GNU sed Remove a couple of incorrect backslashes from expressions used to generate lists of exported symbols so it works with busybox sed. [John Spencer]
2013-05-14 22:29:26 +04:00
Fix exported symbols regex for non-GNU busybox sed.
commands: accept --yes globally Accept --yes on all commands, even ones that don't today have prompts, so that test scripts that don't care about interactive prompts no longer need to deal with them. But continue to mention --yes only in the command prototypes that actually use it.
2013-05-14 21:45:37 +04:00
Accept --yes in all commands so test scripts can be simpler.
Fix alignment of PV data area if detected alignment less than 1 MB This fixes a long standing regression since LVM2 2.02.74 (commit 4efb1d9c, "Update heuristic used for default and detected data alignment.") The default PE alignment could be used (via MAX()) even if it was determined that the device's MD stripe width, or minimal_io_size or optimal_io_size were not factors of the default PE alignment (either 64K or the newer default of 1MB, etc). This bug would manifest if the default PE alignment was larger than the overriding hint that the device provided (e.g. default of 1MB vs optimal_io_size of 768K). Signed-off-by: Mike Snitzer <snitzer@redhat.com>
2013-05-13 23:56:47 +04:00
Fix alignment of PV data area if detected alignment less than 1 MB (2.02.74).
mm: fix leak in fail path If the dm_realloc would fail, the already allocate _maps_buffer memory would have been lost (overwritten with NULL). Fix this by using temporary line buffer. Also add a minor cleanup to set end of buffer to '\0', only when we really know the file size fits the preallocated buffer.
2013-05-13 14:59:38 +04:00
Fix memory resource leak in memlocking error path.
toolcontext: check dm version lazily for udev_fallback setting Setting the cmd->default_settings.udev_fallback also requires DM driver version check. However, this caused useless mapper/control access with ioctl if not needed actually. For example if we're not using activation code, we don't need to know the udev_fallback as there's no node and symlink processing. For example, this premature mapper/control access caused problems when using lvm2app even when no activation happens - there are situations in which we don't need to use mapper/control, but still need some of the lvm2app functionality. This is also the case for lvm2-activation systemd generator which just needs to look at the lvm2 configuration, but it shouldn't touch mapper/control.
2013-05-13 13:46:24 +04:00
Fix premature DM version checking which caused useless mapper/control access.
report: show active state of LV For non clustered VG - show "active"/"" For clustered VG its more complex: "local exclusive" "remote exclusive" "locally" "remotely"
2013-04-25 14:12:05 +04:00
Add "active" LV reporting field to show activation state.
report: show dmeventd monitoring status Add new lvs segment field 'Monitor' showing 3 states: "monitored" - LV is monitored by dmeventd. "not monitored" - LV is currently not being monitored by dmeventd "" (empty) - LV does not support monitoring, or dmeventd support is not compiled in.
2013-04-25 14:07:57 +04:00
Add "monitor" segment reporting field to show dmevent monitoring status.
man: lvextend --use-policies Add missing man info.
2013-04-25 01:41:05 +04:00
Document lvextend --use-policies option in man.
snapshot: rework cluster creation and removal Support for exclusive activation of snapshots revealed some problems. When snapshot is created, COW LV is activated first (for clearing) and then it's transformed into snapshot's COW LV, but it has left the lock for such LV active in cluster and this lock could not have been removed from dlm, unless snapshot has been removed within same dlm session. If the user tried to remove snapshot after rebooting node, the lock was missing, and COW LV could not have been detached. Patch modifes the approach in this way: Always deactivate COW LV for clustered vg after clearing (so it's activated again via imlicit snapshot activation rule when snapshot is activated). When snapshot is removed, activate COW LV as independend LV, so the lock will exist for such LV, but only when the snapshot is active. Also add test case for testing snapshot removal after cluster reboot.
2013-04-21 12:37:52 +04:00
Fix creation and removal of clustered snapshot.
clvmd: avoid pretesting of dev availability Patch fixes hidden problem with lvm metadata caching. When the pretest was made, only the commited data have been cached back since the call lv_info_by_lvid() triggers mda read operation. However call of lv_suspend_if_active() also reads precommited metadata. The problem is visible in this sequence of calls: vg_write(), suspend_lv(), vg_commit(), resume_lv() which may end with leaving outdated mda in lvm cache, since vg_write() drops cached metadata and vg_commit() only transforms precommited to commited metadata, but in the case of pretesting we have no precommited mda available so the cache will continue to use old metadata. This happens, when suspend LV is inactive.
2013-04-21 12:11:29 +04:00
Fix clvmd caching of metadata when suspending inactive volumes.
config: merge timestamps Merging multiple config files together needs to know newest (highest) timestamp of merged files. Persistent cache file is being used only in case, the config file is older then .cache file.
2013-04-23 14:24:17 +04:00
Find newest timestamp of merged config files.
vgread: fix fid transfer for lvm1 and pool format Assign fid as the last step before returning VG. Make the format reader for 'lvm1' and 'pool' equal to 'lvm2' format reader. It has caused memory corruption to lvmetad as it later calls destroy_instance() to allocated fid. This patch should fix problems with crashing test lvmetad-lvm1.sh.
2013-04-21 23:36:08 +04:00
Fix assignment order for vg fid for lvm1 and pool format.
thin: fix resource leak in err path If the devices list could not have been obtained, FILE* was leaked.
2013-04-21 14:19:25 +04:00
Fix memleak in dmeventd thin plugin in device list obtaining err path.
thin: explicitly avoid pvmove operation So far we do not support pvmove for thin volumes and thin pools.
2013-04-21 10:49:17 +04:00
Add explicit message about unsupported pvmove for thin/thinpool volumes.
lvmetad: fix error paths Also add missing goto out on error. Error path missed return NULL leading to double free of enc_value.
2013-04-19 23:19:54 +04:00
Fix lvmetad error path in lvmetad_vg_lookup() for null vgname.
clmvd: fix responce status Failing status code is expected to be 0. Also do not return '*response' as pointer which has been already free().
2013-04-19 23:11:32 +04:00
Fix clvmd _cluster_request() return code in memory fail path.

Add lvchange --[raid]writemostly/writebehind support for RAID1
tools: add common lv_change_activate Move common code for changing activation state from vgchange and lvchange to one function. Fix the order of checks - so we always implicitelly activate snapshots and thin volumes in exclusive mode, and we do not allow local deactivation for them.
2013-04-11 15:51:08 +04:00
Add lv_change_activate() for common activation code in vg/lvchange.
commandline: add prefix aliases for raid options Accept --raidwritemostly as well as --writemostly etc.

Improve lvcreate, lvconvert and lvm man pages.
pv_write: clean up non-orphan format1 PV write ...to not pollute the common and format-independent code in the abstraction layer above. The format1 pv_write has common code for writing metadata and PV header by calling the "write_disks" fn and when rewriting the header itself only (e.g. just for the purpose of changing the PV UUID) during the pvchange operation, we had to tweak this functionality for the format1 case and we had to assign the PV the orphan state temporarily. This patch removes the need for this format1 tweak and it calls the write_disks with appropriate flag indicating whether this is a PV write call or a VG write call, allowing for metatada update for the latter one. Also, a side effect of the former tweak was that it effectively invalidated the cache (even for the non-format1 PVs) as we assigned it the orphan state temporarily just for the format1 PV write to pass. Also, that tweak made it difficult to directly detect whether a PV was part of a VG or not because the state was incorrect. Also, it's not necessary to backup and restore some PV fields when doing a PV write: orig_pe_size = pv_pe_size(pv); orig_pe_start = pv_pe_start(pv); orig_pe_count = pv_pe_count(pv); ... pv_write(pv) ... pv->pe_size = orig_pe_size; pv->pe_start = orig_pe_start; pv->pe_count = orig_pe_count; ...this is already done by the layer below itself (the _format1_pv_write fn). So let's have this cleaned up so we don't need to be bothered about any 'format1 special case for pv_write' anymore.
2013-03-25 17:30:40 +04:00
Clean up format1 PV write to remove a need for an orphan VG for it to pass.
WHATS_NEW: vgextend and PV with 0 MDAs
2013-03-19 18:41:21 +04:00

refactor: rename embedding area -> bootloader area
2013-05-28 14:37:22 +04:00
Add PV header extension: extension version, flags and bootloader areas.
thin: lvconvert support for external origin Add basic support for converting LV into an external origin volume. Syntax: lvconvert --thinpool vg/pool --originname renamed_origin -T origin It will convert volume 'origin' into a thin volume, which will use 'renamed_origin' as an external read-only origin. All read/write into origin will go via 'pool'. renamed_origin volume is read-only volume, that could be activated only in read-only mode, and cannot be modified.
2013-02-05 14:26:27 +04:00
Initial support for lvconvert of thin external origin.

vgimport '--force' now allows import of VGs with missing PVs.
pvcreate: fix alignment to incorporate alignment offset if PV has 0 MDAs If zero metadata copies are used, there's no further recalculation of PV alignment that happens when adding metadata areas to the PV and which actually calculates the alignment correctly as a matter of fact. So fix this for "PV without MDA" case as well. Before this patch: [1] raw/~ # pvcreate --dataalignment 8m --dataalignmentoffset 4m --metadatacopies 1 /dev/sda Physical volume "/dev/sda" successfully created [1] raw/~ # pvs -o pv_name,pe_start PV 1st PE /dev/sda 12.00m [1] raw/~ # pvcreate --dataalignment 8m --dataalignmentoffset 4m --metadatacopies 0 /dev/sda Physical volume "/dev/sda" successfully created [1] raw/~ # pvs -o pv_name,pe_start PV 1st PE /dev/sda 8.00m After this patch: [1] raw/~ # pvcreate --dataalignment 8m --dataalignmentoffset 4m --metadatacopies 1 /dev/sda Physical volume "/dev/sda" successfully created [1] raw/~ # pvs -o pv_name,pe_start PV 1st PE /dev/sda 12.00m [1] raw/~ # pvcreate --dataalignment 8m --dataalignmentoffset 4m --metadatacopies 0 /dev/sda Physical volume "/dev/sda" successfully created [1] raw/~ # pvs -o pv_name,pe_start PV 1st PE /dev/sda 12.00m Also, remove a superfluous condition "pv->pe_start < pv->pe_align" in: if (pe_start == PV_PE_START_CALC && pv->pe_start < pv->pe_align) pv->pe_start = pv->pe_align ... This part of the condition is not reachable as with the PV_PE_START_CALC, we always have pv->pe_start set to 0 from the PV struct initialisation (...the pv->pe_start value is just being calculated).
2013-02-21 17:47:49 +04:00
Fix PV alignment to incorporate alignment offset if the PV has zero MDAs.

Add global/raid10_segtype_default to lvm.conf.
Allow removal or replacement of RAID LV components that are error segments.
RAID: Make 'vgreduce --removemissing' work with RAID LVs Currently it is impossible to remove a failed PV which has a RAID LV on it. This patch fixes the issue by replacing the failed PV with an 'error' segment within the affected sub-LVs. Once there is no longer a RAID LV using the PV, it can be removed. Most often, it is better to replace a failed RAID device with a spare. (You can use 'lvconvert --repair <vg>/<LV>' to accomplish that.) However, if there are no spares in the volume group and none will be added, it is useful to be able to removed the failed device. Following patches address the ability to perform 'lvconvert' operations on RAID LVs that contain sub-LVs composed of 'error' segments.

Make 'vgreduce --removemissing' able to handle RAID LVs with missing PVs.

blkdeactivate: fix handling of nested mountpoints and mangled mount paths. If there was a nested mountpoint inside an existing mount path, blkdeactivate could fail to unmount such a mountpoint as it needs to deactivate the deepest path first and continue upwards. For example the simplest reproducer: [root@rhel6-a ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 4G 0 disk |-vg-lvol0 (dm-2) 253:2 0 32M 0 lvm /mnt/a `-vg-lvol1 (dm-3) 253:3 0 32M 0 lvm /mnt/a/b Before this patch: [root@rhel6-a ~]# blkdeactivate -u Deactivating block devices: UMOUNT: unmounting vg-lvol0 (dm-2) mounted on /mnt/a umount: /mnt/a: device is busy. (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1)) UMOUNT: unmounting vg-lvol1 (dm-3) mounted on /mnt/a/b LVM: deactivating Logical Volume vg/lvol1 (deactivation of vg/lvol0 is skipped as /mnt/a that is on lvol0 can't be unmounted - it still has /mnt/a/b as nested mountpoint!) With this patch applied: [root@rhel6-a ~]# blkdeactivate -u Deactivating block devices: UMOUNT: unmounting vg-lvol1 (dm-3) mounted on /mnt/a/b UMOUNT: unmounting vg-lvol0 (dm-2) mounted on /mnt/a LVM: deactivating Logical Volume vg/lvol0 LVM: deactivating Logical Volume vg/lvol1 === Also, this patch contains a fix for processing mangled mount paths: [root@rhel6-a ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 4G 0 disk `-vg-lvol0 (dm-2) 253:2 0 32M 0 lvm /mnt/x y z [root@rhel6-a ~]# lsblk -r vg-lvol0 253:2 0 32M 0 lvm /mnt/x\x20y\x20z (the mount path is mangled with \xNN that is visible in raw lsblk output only and which is used in blkdeactive as well) Before this patch: [root@rhel6-a ~]# blkdeactivate -u Deactivating block devices: umount: /mnt/x\x20y\x20z: not found After this patch applied: [root@rhel6-a ~]# blkdeactivate -u Deactivating block devices: UMOUNT: unmounting vg-lvol0 (dm-2) mounted on /mnt/x\x20y\x20z LVM: deactivating Logical Volume vg/lvol0

Use LC_ALL to set locale in daemons and fsadm instead of lower priority LANG.
Avoid crash-inducing race in lvmetad when VG disappears during rename.
logging: add debug classes Add log/debug_classes to lvm.conf to allow debug messages to be classified and filtered at runtime. The dm_errno field is only used by log_error(), so I've redefined it for log_debug() messages to hold the message class. By default, all existing messages appear, but we can add categories that generate high volumes of data, such as logging all traffic to/from lvmetad.
2013-01-08 02:25:19 +04:00
Add log/debug_classes to lvm.conf to control debug log messages.
pvscan: synchronize with udev if pvscan --cache is used. We need to call sync_local_dev_names directly as pvscan uses VG_GLOBAL lock and this one *does not* cause the synchronization (sync_dev_names) to be called on unlock (VG_GLOBAL is not a real VG): define unlock_vg(cmd, vol) do { \ if (is_real_vg(vol)) \ sync_dev_names(cmd); \ (void) lock_vol(cmd, vol, LCK_VG_UNLOCK); \ } while (0) Without this fix, we end up without udev synchronization for the pvscan --cache (mainly for -aay that causes the VGs/LVs to be autoactivated) and also udev synchronization cookies are then left in the system since they're not managed properly (code before sets up udev sync cookies, but we have to call dm_udev_wait at least once after that to do the wait and cleanup).
2012-12-21 13:54:31 +04:00
Synchronize with udev in pvscan --cache and fix dangling udev_sync cookies.
activation: fix autoactivation to not trigger on each PV change Before, the pvscan --cache -aay was called on each ADD and CHANGE uevent (for a device that is not a device-mapper device) and each CHANGE event (for a PV that is a device-mapper device). This causes troubles with autoactivation in some cases as CHANGE event may originate from using the OPTION+="watch" udev rule that is defined in 60-persistent-storage.rules (part of the rules provided by udev directly) and it's used for all block devices (except fd*|mtd*|nbd*|gnbd*|btibm*|dm-*|md* devices). For example, the following sequence incorrectly activates the rest of LVs in a VG if one of the LVs in the VG is being removed: [root@rhel6-a ~]# pvcreate /dev/sda Physical volume "/dev/sda" successfully created [root@rhel6-a ~]# vgcreate vg /dev/sda Volume group "vg" successfully created [root@rhel6-a ~]# lvcreate -l1 vg Logical volume "lvol0" created [root@rhel6-a ~]# lvcreate -l1 vg Logical volume "lvol1" created [root@rhel6-a ~]# vgchange -an vg 0 logical volume(s) in volume group "vg" now active [root@rhel6-a ~]# lvs LV VG Attr LSize Pool Origin Data% Move Log Cpy%Sync Convert lvol0 vg -wi------ 4.00m lvol1 vg -wi------ 4.00m [root@rhel6-a ~]# lvremove -ff vg/lvol1 Logical volume "lvol1" successfully removed [root@rhel6-a ~]# lvs LV VG Attr LSize Pool Origin Data% Move Log Cpy%Sync Convert lvol0 vg -wi-a---- 4.00m ...so the vg was deactivated, then lvol1 removed, and we end up with lvol1 removed (which is ok) BUT with lvol0 activated (which is wrong)!!! This is because after lvol1 removal, we need to write metadata to the underlying device /dev/sda and that causes the CHANGE event to be generated (because of the WATCH udev rule set on this device) and this causes the pvscan --cache -aay to be reevaluated. We have to limit this and call pvscan --cache -aay to autoactivate VGs/LVs only in these cases: --> if the *PV is not a dm device*, scan only after proper device addition (ADD event) and not with any other changes (CHANGE event) --> if the *PV is a dm device*, scan only after proper mapping activation (CHANGE event + the underlying PV in a state "just activated")
2012-12-21 13:34:48 +04:00
Fix autoactivation to not autoactivate VG/LV on each change of the PVs used.
RAID: Limit replacement of devices when array is not in-sync. If a RAID array is not in-sync, replacing devices should not be allowed as a general rule. This is because the contents used to populate the incoming device may be undefined because the devices being read where not in-sync. The kernel enforces this rule unless overridden by not allowing the creation of an array that is not in-sync and includes a devices that needs to be rebuilt. Since we cannot know the sync state of an LV if it is inactive, we must also enforce the rule that an array must be active to replace devices. That leaves us with the following conditions: 1) never allow replacement or repair of devices if the LV is in-active 2) never allow replacement if the LV is not in-sync 3) allow repair if the LV is not in-sync, but warn that contents may not be recoverable. In the case where a user is performing the repair on the command line via 'lvconvert --repair', the warning is printed before the user is prompted if they would like to replace the device(s). If the repair is automated (i.e. via dmeventd and policy is "allocate"), then the device is replaced if possible and the warning is printed.
2012-12-19 00:40:42 +04:00
Limit RAID device replacement to repair only if LV is not in-sync.
Disallow RAID device replacement or repair on inactive LVs.

mirrors: fix leak in device_is_usable mirror check Function _ignore_blocked_mirror_devices was not release allocated strings images_health and log_health. In error paths it was also not releasing dm_task structure. Swaped return code of _ignore_blocked_mirror_devices and use 1 as success. In _parse_mirror_status use log_error if memory allocation fails and few more errors so they are no going unnoticed as debug messages. On error path always clear return values and free strings. For dev_create_file use cache mem pool to avoid memleak.

pvmove/RAID: Disallow pvmove on RAID LVs until properly handled Attempting pvmove on RAID LVs replaces the kernel RAID target with a temporary pvmove target, ultimately destroying the RAID LV. pvmove must be prevented on RAID LVs for now. Use 'lvconvert --replace old_pv vg/lv new_pv' if you want to move an image of the RAID LV.

Fix lvm2app to return all property sizes in bytes (not sectors).
udev: recognize DM_DISABLE_UDEV environment variable Setting this environment variable will cause a full fallback to old direct node and symlink management in libdevmapper and lvm2. It means: - disabling udev synchronization (--noudevsync in dmsetup and --noudevsync + activation/udev_sync=0 lvm2 config) - disabling dm and any subsystem related udev rules (--noudevrules in dmsetup and activation/udev_rules=0 lvm2 config) - management of nodes/symlinks under /dev directly by libdevmapper/lvm2 (--verifyudev in dmsetup and activation/verify_udev_operations=1 lvm2 config) - not obtaining any device list from udev database (devices/obtain_device_list_from_udev=0 lvm2 config) Note: we could set all of these before - there's no functional change! However the DM_DISABLE_UDEV environment variable is a nice shortcut to make it easier for libdevmapper users so that one can switch off all of the udev management off at one go directly on the command line, without a need to modify any source or add any extra switches.
2012-11-29 17:03:48 +04:00
Recognize DM_DISABLE_UDEV environment variable for a complete fallback.
udev: do not verify udev operations for --noudevsync If udev synchronization is disabled by means of --noudevsync option, we should disable just the synchronization and nothing else. The udev fallback (verifying udev operations and fixing the nodes/symlinks if found incorrect) is orthogonal and controlled by a separate activation/verify_udev_operations configuration option.

Add lv_is_active_locally and use instead of most local lv_info calls.
rephrasing: miscellaneous changes Miscellaneous changes to messages, man pages, comments and WHATS_NEW.
2013-05-15 04:50:42 +04:00
Reduce some log_error messages to log_warn where we don't fail.
Remove python liblvm object. systemdir can only be changed using env var now.
cleanup: switch log_error to log_warn Use log_warn to print non-fatal warning messages. Use of log_error would confuse checker for testing whether proper error has been reported for some real error.

Allow non power of 2 thin chunk sizes if thin pool driver supports that.
[lv|vg]change: Allow limited metadata changes when PVs are missing A while back, the behavior of LVM changed from allowing metadata changes when PVs were missing to not allowing changes. Until recently, this change was tolerated by HA-LVM by forcing a 'vgreduce --removemissing' before trying (again) to add tags to an LV and then activate it. LVM mirroring requires that failed devices are removed anyway, so this was largely harmless. However, RAID LVs do not require devices to be removed from the array in order to be activated. In fact, in an HA-LVM environment this would be very undesirable. Device failures in such an environment can often be transient and it would be much better to restore the device to the array than synchronize an entirely new device. There are two methods that can be used to setup an HA-LVM environment: "clvm" or "tagging". For RAID LVs, "clvm" is out of the question because RAID LVs are not supported in clustered VGs - not even in an exclusively activated manner. That leaves "tagging". HA-LVM uses tagging - coupled with 'volume_list' - to ensure that only one machine can have an LV active at a time. If updates are not allowed when a PV is missing, it is impossible to add or remove tags to allow for activation. This removes one of the most basic functionalities of HA-LVM - site redundancy. If mirroring or RAID is used to replicate the storage in two data centers and one of them goes down, a server and a storage device are lost. When the service fails-over to the alternate site, the VG will be "partial". Unable to add a tag to the VG/LV, the RAID device will be unable to activate. The solution is to allow vgchange and lvchange to alter the LVM metadata for a limited set of options - --[add|del]tag included. The set of allowable options are ones that do not cause changes to the DM kernel target (like --resync would) or could alter the structure of the LV (like allocation or conversion).
2012-10-10 20:33:10 +04:00
Allow limited metadata changes when PVs are missing via [vg|lv]change.
lvchange: do not start dmevent for resyn If monitoring is disabled in lvm.conf, avoid its starting and preserve DMEVENTD_MONITOR_IGNORE settings internally.
2012-10-09 14:20:47 +04:00
Do not start dmeventd for lvchange --resync when monitoring is off.
Remove pvscan --cache from lvm2-lvmetad init script. This is not needed anymore as the scan is called transparently within the first LVM command that queries lvmetad.
2012-10-15 14:58:23 +04:00
Remove pvscan --cache from lvm2-lvmetad init script.
systemd: remove ExecStartPost from lvm2-lvmetad.service. The ExecStartPost with pvscan --cache in lvm2-lvmetad.service is not needed now as this is called transparently within the first LVM command that queries lvmetad.
2012-10-08 18:49:54 +04:00
Remove ExecStartPost with pvscan --cache from lvm2-lvmetad.service.
report: call snapshot percent with cow only Ensure lv_snapshot_percent is used only with snapshot LVs.
2012-10-08 14:06:30 +04:00
Report invalid percentage for property snap_percent of non-snaphot LVs.
release: prepare for release
2012-10-15 18:19:32 +04:00
Disallow conversion of thin LVs to mirrors.
lvm2api: fix data percent reporting for thin, snap Use same logic for lvm2api as we use lvs reporting. data_percent is meant to be superset for snap_percent.
2012-10-05 11:56:50 +04:00
Fix lvm2api data_percent reporting for thin volumes.
RAID: Do not allow RAID LVs in a cluster volume group. It would be possible to activate a RAID LV exclusively in a cluster volume group, but for now we do not allow RAID LVs to exist in a clustered volume group at all. This has two components: 1) Do not allow RAID LVs to be created in a clustered VG 2) Do not allow changing a VG from single-machine to clustered if there are RAID LVs present.
2012-10-04 00:52:54 +04:00
Do not allow RAID LVs in a clustered volume group.
release: prepare for release
2012-10-15 18:19:32 +04:00
Add --discards to lvconvert.
Add --poolmetadata to lvconvert and support thin meta/data dev stacking.
thin: lvchange allows to change perms of thin snap Thin snapshots are individual thin volumes so they can have its own control for rw permissions.
2012-09-19 16:55:34 +04:00
Support changes of permissions for thin snapshot volumes.
liblvm: insert layer with subvolume renames Rename also subvolumes if we are inserting _tdata layer. (Currently it breaks mirrors if it would be generic, needs fixing).
2012-09-06 17:21:18 +04:00
Enhance insert_layer_for_lv() with recursive rename for _tdata LVs.
thin: origin only suspend Skip tree creating when used with origin_only flag.
2012-06-05 13:28:01 +04:00
Skip building dm tree for thin pool when called with origin_only flag.
liblvm: add lv_rename_update Support lv_rename without directly updating metatata. It can save some metadata commits in some cases, i.e. when LVs are offline.
2012-09-27 11:48:25 +04:00
Add internal lv_rename_update() to rename LV without updating mda.
release: prepare for release
2012-10-15 18:19:32 +04:00
Ensure descriptors 0,1,2 are always available, using /dev/null if necessary.
Use /proc/self/fd when available for closing opened descriptors efficiently.
configure: fix --enable-testing Add missing pkg init for configure --enable-testing.
2012-10-01 16:34:07 +04:00
Add missing pkg init with --enable-testing in configure.in (2.02.71).
RAID: Fix problems with creating, extending and converting large RAID LVs MD's bitmaps can handle 2^21 regions at most. The RAID code has always used a region_size of 1024 sectors. That means the size of a RAID LV was limited to 1TiB. (The user can adjust the region_size when creating a RAID LV, which can affect the maximum size.) Thus, creating, extending or converting to a RAID LV greater than 1TiB would result in a failure to load the new device-mapper table. Again, the size of the RAID LV is not limited by how much space is allocated for the metadata area, but by the limitations of the MD bitmap. Therefore, we must adjust the 'region_size' to ensure that the number of regions does not exceed the limit. I've added code to do this when extending a RAID LV (which covers 'create' and 'extend' operations) and when up-converting - specifically from linear to RAID1.
2012-09-28 01:51:22 +04:00
Fix inability to create, extend or convert to a large (> 1TiB) RAID LV.
release: prepare for release
2012-10-15 18:19:32 +04:00
Split out daemon-io from daemon-shared and always build libdaemonclient.
Update lvmetad communications to cope with clients using different filters.
lvs: add partial attribute
2012-09-19 15:49:40 +04:00
Add (p)artial attribute to lvs.
discards: skip when removing LVs on missing PVs Don't try to issue discards to a missing PV to avoid segfault. Prevent lvremove from removing LVs that have any part missing. https://bugzilla.redhat.com/857554
2012-09-19 15:48:56 +04:00
Don't try to issue discards to a missing PV to avoid segfault.
RAID1: Clear the LV_NOTSYNCED flag when a RAID1 LV is converted to linear Failing to clear the LV_NOTSYNCED flag when converting a RAID1 LV to linear can result in the flag being present after an upconvert - even if the sync is performed when upconverting.
2012-09-15 01:26:53 +04:00
Clear LV_NOSYNCED flag when a RAID1 LV is converted to a linear LV.
RAID1: Like mirrors, do not allow adding images to LV created w/ --nosync Mirrors do not allow upconverting if the LV has been created with --nosync. We will enforce the same rule for RAID1. It isn't hugely critical, since the portions that have been written will be copied over to the new device identically from either of the existing images. However, the unwritten sections may be different, causing the added image to be a hybrid of the existing images. Also, we are disallowing the addition of new images to a RAID1 LV that has not completed the initial sync. This may be different from mirroring, but that is due to the fact that the 'mirror' segment type "stacks" when adding a new image and RAID1 does not. RAID1 will rebuild a newly added image "inline" from the existant images, so they should be in-sync.
2012-09-15 01:12:52 +04:00
Disallow RAID1 upconvert if the LV was created with --nosync.
systemd: depend on systemd-udev-settle unit in activation unit The "fedora-wait-storage.service" that the "lvm2-activation.service" had as a dependency (which was fedora-specific solution anyway) is obsolete now as this unit called "modprobe scsi_wait_scan" which is not used anymore. The "fedora-wait-storage.service" had "systemd-udev-settle" as its dependency, so let's depend on this one directly now, bypassing the out-dated "fedora-wait-storage.service".
2012-09-12 13:30:13 +04:00
Depend on systemd-udev-settle in units generated by activation generator.
release: prepare for release
2012-10-15 18:19:32 +04:00
Fix vgchange -aay not to activate non-matching LVs that follow a matching LV.
Fix lvchange --resync for RAID LVs which had no effect.
Restructure mirror resync code.
cleanup: Reduce indentation by short-circuiting function By changing the conditional for resyncing mirrors with core-logs a bit, we can short-circuit the rest of the function for that case and reduce the amount of indenting in the rest of the function. This cleanup will simplify future patches aimed at properly handling the resync of RAID LVs.
2012-09-11 21:55:17 +04:00
Disallow addition of RAID images until the array is in-sync.
RAID: '--test' should not cause a valid create command to fail It is necessary when creating a RAID LV to clear the new metadata areas. Failure to do so could result in a prepopulated bitmap that would cause the new array to skip syncing portions of the array. It is a requirement that the metadata LVs be activated and cleared in the process of creating. However in test mode, this requirement should be lifted - no new LVs should be created or written to.
2012-09-05 23:32:06 +04:00
Fix RAID LV creation with '--test' so valid commands do not fail.
lvm2api: extend lvm2api with lvm_lv_rename Add support for LV rename.
2011-01-28 01:41:32 +03:00
Add lvm_lv_rename() to lvm2api.
setvbuf: close and reopen stream before change Fix setvbuf code by closing and reopening stream before changing buffer. But we need to review what this code is doing embedded inside a library function rather than the simpler original form being run independently at the top of main() by tools that need it.
2012-08-26 03:19:52 +04:00
Fix setvbuf code by closing and reopening stream before changing buffer.
buffering: use unbuffered silent mode for liblvm Disable private buffering when using liblvm. When private stdin/stdout buffering is not used always use silent mode.
2012-08-26 03:15:45 +04:00
Disable private buffering when using liblvm.
When private stdin/stdout buffering is not used always use silent mode.
config: add silent mode Accept -q as the short form of --quiet. Suppress non-essential standard output if -q is given twice. Treat log/silent in lvm.conf as equivalent to -qq. Review all log_print messages and change some to log_print_unless_silent. When silent, the following commands still produce output: dumpconfig, lvdisplay, lvmdiskscan, lvs, pvck, pvdisplay, pvs, version, vgcfgrestore -l, vgdisplay, vgs. [Needs checking.] Non-essential messages are shifted from log level 4 to log level 5 for syslog and lvm2_log_fn purposes.
2012-08-25 23:35:48 +04:00
Add log/silent to lvm.conf equivalent to -qq.
Suppress non-essential stdout with -qq.
Switch non-essential log_print messages to log_print_unless_silent.
Use -q as short form of --quiet.

2012-08-23 13:01:00 +04:00
Fix dereference of NULL in lvmetad error path logging.
lvmetad: fix memleaks Release allocated buffers in daemon_logf, daemon_log_parse

Add support for lvcreate --discards.
release: prepare for release
2012-10-15 18:19:32 +04:00
Correct the discards field in the lvs manpage (2.02.97).
Use proper condition to check for discards settings unsupported by kernel.
Reinstate correct default to ignore discards for thin metadata from old tools.
Issue error message when -i and -m args do not match specified RAID type.
lvmetad: use -l for logging level not -d
2012-10-15 13:44:43 +04:00
Change lvmetad logging syntax from -ddd to -l {all|wire|debug}.
lvmetad: document and tidy cmdline args Try to bring the lvmetad usage text and man page closer to the code. There seem to be 3 useful ways to use -d with lvmetad at the moment: -d all -d wire -d debug (They can also be comma-separated like -d wire,debug.) Prior to the last release, -d, -dd and -ddd were supported. Fail if an unrecognised debug arg is supplied on the command line. Change -V to report the same version as the lvm binary: previously it just reported version 0.
2012-10-15 05:06:27 +04:00
Add new libdaemon logging infrastructure.
thin: default discards for old mda is IGNORE If the discard was not set in metadata, use IGNORE, as this is the equivalent behavior for this case.

args: increase major:minor limit to 4095:1048575 Remove the limit for major and minor number arguments used while specifying persistent numbers via -My --major <major> --minor <minor> option which was set to 255 before. Follow the kernel limit instead which is 12 bits for major and 20 bits for minor number (kernel >= 2.6 and LVM formats that does not have FMT_RESTRICTED_LVIDS - so still keep the old limit of 255 for lvm1 format).

2012-07-27 23:19:28 +04:00
No longer capitalise first LV attribute char for invalid snapshots.
vgextend: Allow PVs to be added to VGs that have PVs missing Allowing people to add devices to a VG that has PVs missing helps people avoid the inability to repair RAID LVs in certain cases. For example, if a user creates a RAID 4/5/6 LV using all of the available devices in a VG, there will be no spare devices to repair the LV with if a device should fail. Further, because the VG is missing a device, new devices cannot be added to allow the repair. If 'vgreduce --removemissing' were attempted, the "MISSING" PV could not be removed without also destroying the RAID LV. Allowing vgextend to operate solves the circular dependency. When the PV is added by a vgextend operation, the sequence number is incremented and the 'MISSING' flag is put on the PVs which are missing.
2012-07-27 02:06:06 +04:00
Allow vgextend to add PVs to a VG that is missing PVs.
filters: Add Micron PCIe SSDs (mtip32xx) Recognise Micron PCIe SSDs in filter and move array out to device-types.h.
2012-07-26 05:26:40 +04:00

2012-08-07 23:41:45 +04:00
Fix dumpconfig <node> to print only <node> without its siblings. (2.02.89)
daemon-server: fix error message on daemon shutdown If a daemon (like lvmetad that is using common daemon-server code) received a kill signal that was supposed to shut the daemon down, a spurious message was issued: "Failed to handle a client connection". This happened if the kill signal came just in the middle of waiting for a client request in "select" - the request that was supposed to be handled was blank at that moment of course.
2012-07-19 18:45:08 +04:00
Do not issue "Failed to handle a client connection" error if lvmetad killed.
thin: use discards as plural rather than singular Global change from --discard to --discards, as that feels more natural.

2012-08-07 23:41:45 +04:00
Set discard and external snapshot features if thin pool target is vsn 1.1+.
Count percentage of completeness upwards not downwards when merging snapshot.
activate: skip manual activation for --sysinit -aay When --sysinit -a ay is used with vg/lvchange and lvmetad is up and running, we should skip manual activation as that would be a useless step - all volumes are autoactivated once all the PVs for a VG are present. If lvmetad is not active at the time of the vgchange --sysinit -a ay call, the activation proceeds in standard 'manual' way. This way, we can still have vg/lvchange --sysinit -a ay called unconditionally in system initialization scripts no matter if lvmetad is used or not.
2012-07-10 15:49:46 +04:00
Skip activation when using vg/lvchange --sysinit -a ay and lvmetad is active.
RAID: Fix extending size of RAID 4/5/6 logical volumes. Reducing a RAID 4/5/6 LV or extending it with a different number of stripes is still not implemented. This patch covers the "simple" case where the LV is extended with the same number of stripes as the orginal.
2012-06-26 18:44:54 +04:00
Fix extending RAID 4/5/6 logical volumes

Fix _alloc_parallel_area to avoid picking already-full areas for raid devices.
initscript: call vgchange -aay instead of -aly The clmvd init script called "vgchange -aly" before to activate all VGs in cluster environment. This activated all VGs, no matter if it was clustered or not. Auto activation for clustered VGs is not supported yet so the behaviour of -aay is still the same as before for clustered VGs. However, for non-clustered VGs, we need to check with the activation/auto_activation_volume_list whether the VG/LV should be activated on boot or not.
2012-06-28 14:49:33 +04:00
Use vgchange -aay instead of vgchange -ay in clmvd init script.
conf: add activation/auto_activation_volume_list
2012-06-26 14:17:23 +04:00
Add activation/auto_activation_volume_list to lvm.conf.
WHATS_NEW: update Update WHATS_NEW.
2012-06-29 02:14:27 +04:00
Add --activate ay to lvcreate, lvchange, pvscan and vgchange.
activate: add autoactivation hooks Define an 'activation_handler' that gets called automatically on PV appearance/disappearance while processing the lvmetad_pv_found and lvmetad_pv_gone functions that are supposed to update the lvmetad state based on PV availability state. For now, the actual support is for PV appearance only, leaving room for PV disappearance support as well (which is a more complex problem to solve as this needs to count with possible device stack). Add a new activation change mode - CHANGE_AAY exposed as '--activate ay/-aay' argument ('activate automatically'). Factor out the vgchange activation functionality for use in other tools (like pvscan...).
2012-06-27 16:59:34 +04:00
Add support for volume autoactivation using lvmetad.
args: add --activate synonym for --available arg We're refererring to 'activation' all over the code and we're talking about 'LVs being activated' all the time so let's use 'activation/activate' everywhere for clarity and consistency (still providing the old 'available' keyword as a synonym for backward compatibility with existing environments).
2012-06-27 15:48:31 +04:00
Add --activate synonym for --available arg and prefer --activate.
discards: don't discard reconfigured extents Update release_lv_segment_area not to discard any PV extents, as it also gets used when moving extents between LVs. Instead, call a new function release_and_discard_lv_segment_area() in the two places where data should be discarded - lv_reduce() and remove_mirrors_from_segments().
2012-06-28 00:53:02 +04:00
Never issue discards when LV extents are being reconfigured, not deleted.
allocation: allow release_lv_segment_area to fail Allow release_lv_segment_area to fail as functions it calls can fail.
2012-06-27 22:37:54 +04:00
Allow release_lv_segment_area to fail as functions it calls can fail.

Fix error paths for regex filter initialization.
Re-enable partial activation of non-thin LVs until it can be fixed. (2.02.90) - The test should be checking the LV as a whole, not just individual segments.

2012-05-09 16:30:56 +04:00
Fix division by zero if PV with zero PE count is used during vgcfgrestore.
Initial support for lvconvert for thin pool volumes. Support has many limitations and lots of FIXMEs inside, however it makes initial task when user creates a separate LV for thin pool data and thin metadata already usable, so let's enable it for testing. Easiest API: lvconvert --chunksize XX --thinpool data_lv metadata_lv More functionality extensions will follow up. TODO: Code needs some rework since a lot of same code is getting copied.
2012-05-09 16:17:06 +04:00

release: WHATS_NEW tidy
2012-06-09 03:29:20 +04:00
Fix lvrename for thin volumes (regression in for_each_sub_lv). (2.02.89)
Fix up-convert when mirror activation is controlled by volume_list and tags.
Warn of deadlock risk when using snapshots of mirror segment type.
2012-05-14 20:18:57 +04:00
Warn of deadlock risk when using snapshots of mirror segment type.
Fix bug in cmirror that caused incorrect status info to print on some nodes. Looking at the code in cmirrord/local.c, we can see the various different request types handled in different ways. Some information that is non-changing does not need to go around the cluster and can be short-circuited. For example, once the cluster mirror is in-sync, it is pointless to continue sending that query around the cluster. We can save network bandwidth and reply directly back to the kernel. When it comes to status information, there are two types 'TABLE' and 'INFO'. The 'TABLE' information never changes and belongs to the group of requests that can be safely short-circuited. The 'STATUS' information can change - and will change if a device fails. Thus it cannot be short-circuited, but this is exactly what was found. The 'STATUS' information request was being short-circuited and therefore never reporting the failure condition to anyone other than the "server" that experienced it directly.
2012-04-26 21:30:49 +04:00
Fix bug in cmirror that caused incorrect status info to print on some nodes.

WHATS_NEW
2012-04-25 13:32:36 +04:00
Fix lvconvert error message for non-mergeable volumes.
Allow a subset of failed devices to be replaced in RAID LVs. If two devices in an array failed, it was previously impossible to replace just one of them. This patch allows for the replacement of some, but perhaps not all, failed devices.
2012-04-25 00:05:31 +04:00
Allow subset of failed devices to be replaced in RAID LVs.
Prevent resume from creating error devices that already exist from suspend. Thanks to agk for providing the patch that prevents resume from attempting (and then failing) to create error devices which already exist; having been created by a corresponding suspend operation.
2012-04-25 00:00:03 +04:00
Prevent resume from creating error devices that already exist from suspend.
Update singlenode locking Support lock conversion Work also with LCK_READ TODO: do more validation.
2012-04-24 16:16:40 +04:00
Improve clmvd singlenode locking for better testing.

release: WHATS_NEW tidy
2012-06-09 03:29:20 +04:00

Fix code that performs RAID device replacement while under snapshot. The code should have been calling [suspend|resume]_lv_origin() rather than [suspend|resume]_lv. This addresses bug 807069.
2012-04-12 07:16:37 +04:00
Fix RAID device replacement code so that it works under snapshot.
Fix inability to split RAID1 image while specifying a particular PV. The logic for resuming the original and newly split LVs was not properly done to handle situations where anything but the last device in the array was split. It did not take into account the possible name collisions that might occur when the original LV undergoes the shifting and renaming of its sub-LVs.

Update man pages to give them all the same look&feel.
Fix lvresize of thin pool for striped devices.
Lvresize rounds upward When given lvresize new size - round upward for stripes - unless we use % and we are at the border of free extents. This patch is not a complete fix and few more cases will need special care.
2012-04-11 16:36:37 +04:00

release: WHATS_NEW tidy
2012-06-09 03:29:20 +04:00
For lvcreate with %FREE support rounding downward stripe alignment.
Change message severity to log_very_verbose for missing dev info in udev db. Libudev does not provide transactions when querying udev database - once we get the list of block devices (devices/obtain_device_list_from_udev=1) and we iterate over the list to get more detailed information about device node and symlink names used etc., the device could be removed just in between we get the list and put a query for more info. In this case, libudev returns NULL value as the device does not exist anymore. Recently, we've added a warning message to reveal such situations. However, this could be misleading if the device is not related to the LVM action we're just processing - the non-related block device could be removed in parallel and this is not an error but a possible and normal operation. (N.B. This "missing info" should not happen when devices are related to the LVM action we're just processing since all such processing should be synchronized with udev and the udev db must always be in consistent state after the sync point. But we can't filter this situation out from others, non-related devices, so we have to lower the message verbosity here for a general solution.)
2012-04-11 13:12:02 +04:00
Change message severity to log_very_verbose for missing dev info in udev db.

2012-06-09 03:29:20 +04:00
Fix lvconvert when specifying removal of a RAID device other than last one.
Fix ability to handle failures in mirrored log in dmeventd plugin. (2.02.89)
Fix unlocking in error path of vgreduce When vg_read fails, it internally unlocks VG if it's been locked, so in error path we should skip unlock_vg for this case. (user would see ugly internal warning)
2012-03-30 18:59:35 +04:00
Fix unlocking volume group in vgreduce in error path.
release: WHATS_NEW tidy
2012-06-09 03:29:20 +04:00
Cope when VG name is part of the supplied name in lvconvert --splitmirrors -n.
Fix exclusive lvmchange -aey to fail if volume is active on different node. Activation on remote node should be tried only if it is masked by tags locally (like when hosttags enabled, IOW activate_lv_excl_local() doesn't return error.) Introduced change caused that lvchange -aey succeeded even if volume was activated exclusively remotely.
2012-03-27 19:53:45 +04:00
Fix exclusive lvchange running from other node. (2.02.89)
Add 'vgscan --cache' functionality for consistency with 'pvscan --cache'. Calling vgscan alone should reuse information from the lvmetad (if running). The --cache option should initiate direct device scan and update lvmetad appropriately (if running). This is mainly for vgscan to behave consistently compared to pvscan.
2012-03-27 15:04:46 +04:00
Add 'vgscan --cache' functionality for consistency with 'pvscan --cache'.
Keep exclusive activation in pvmove if LV is already active. Pvmove should never try to downgrade exclusive lock for LVs. This allows pvmove to work again for exclusive activated LVs.
2012-03-27 00:33:40 +04:00
Keep exclusive activation in pvmove if LV is already active.
Edit WHATS_NEW.
2012-06-07 18:14:19 +04:00
Disallow exclusive pvmove if some affected LVs are not exclusively activated.
Remove unused and wrongly set cluster VG flag from clvmd lock query command.
2012-03-27 00:29:45 +04:00
Remove unused and wrongly set cluster VG flag from clvmd lock query command.
Fix pvmove if LV is activated exclusively but cmirror is not running. In this case we should allow to use local mirror, check for cmirror should apply only for lvconvert/lvcreate. Introduced in 2.02.86 by removing !(lv->status & ACTIVATE_EXCL). (Partially workaround, it is minimalistic patch for now.)
2012-03-23 20:28:40 +04:00
Fix pvmove for exclusively activated LV pvmove in clustered VG. (2.02.86)
Always free hash table also in error path
2012-03-23 14:33:26 +04:00
Always free hash table on update_pvid_to_vgid() in lvmetad.
Update and fix monitoring of thin pool devices Code adds better support for monitoring of thin pool devices. update_pool_lv uses DMEVENTD_MONITOR_IGNORE to not manipulate with monitoring. vgchange & lvchange are checking real thin pool device for existance as we are using _tpool real device and visible LV pool device might not be even active (_tpool is activated implicitely for any thin volume). monitor_dev_for_events is another _lv_postorder like code it might be worth to think about reusing it here - for now update the code to properly monitory thin volume deps. For unmonitoring add extra code to check the usage of thin pool - in case it's in use unmonitoring of thin volume is skipped.

Fix arg_int_value alongside ARG_GROUPABLE --major/--minor for lvcreate/change.
Fix name conflicts that prevent down-converting RAID1 when specifying a device When down-converting a RAID1 device, it is the last device that is extracted and removed when the user does not specify a particular device. However, when a device is specified (and it is not the last), the device is removed and the remaining sub-LVs are "shifted down" to fill the hole. This cause problems when resuming the LV because if the shifted devices were resumed (and thus renamed) before the sub-LV being extracted, there would be a name conflict. The solution is to resume the extracted sub-LVs first so that they can be properly renamed preventing a possible conflict. This addresses bug 801967.
2012-03-16 00:00:54 +04:00
Fix name conflicts that prevent down-converting RAID1 when specifying a device
Improve thin_check option passing Update a way we handle option passing - so we now support path and options with space inside. Fix dm name usage for thin pools with '-' in name. Use new lvm.conf option thin_check_options to pass in options as string array.
2012-03-14 21:12:05 +04:00
Improve thin_check option passing and use configured path.
Add --with-thin-check configure option If specified - use given path without test (Path could be empty) If autodetection is in use - check for command in available PATH.
2012-03-14 21:09:00 +04:00
Add --with-thin-check configure option for path to thin_check.
Fix error message when pvmove LV activation fails with name already in use.
2012-03-14 00:21:26 +04:00
Fix error message when pvmove LV activation fails with name already in use.
Better structure layout for device_info Save some relocation entries and use directly char[]. Since we do not need yes more then 127 partitions per device, use just int8_t. Move lvm_type_filter_destroy into local static function.
2012-03-12 18:40:41 +04:00
Better structure layout for device_info in dev_subsystem_name().

Always use 64bit arithmetic with VG extent_size expression.
Validate udev structures Avoid using NULL pointers from udev. It seems like some older versions of udev were improperly returning NULL in some case, so do not silently break here, and give at least a warning to the user.

Validate udev structures in _insert_udev_dir().
Switch pvscan --cache major:minor to --major --minor.

2012-03-02 21:25:21 +04:00
Fix automatic estimation of metadata device size for thin pool.
Test alloc fail
2012-03-02 01:49:32 +04:00

Add _rimage as reserved suffix
2012-03-01 14:39:21 +04:00
Add _rimage as reserved suffix to lvm.8 man page.
Improve error logging Log errors instead of plain return 0. Check for f->private strdup result.

Improve error logging from mpath filter.
Check for allocation error return ENOMEM when malloc fails.
2012-03-01 13:54:23 +04:00
Check for allocation failure in hold_lock() in clvmd.
Wipe initial 4KiB for non-zeroed thin volumes If the thin pool has disabled zeroing (created with -Zn), we at least clear initial 4KiB of such thin volume (provisions 1st block). If lvcreate is executed with '-an' command will abort (same way like we for normal LV - however for normal LV option -Zn may skip clearing completely, for thin volumes this option is not supported (applies only for pools).
2012-03-01 02:08:57 +04:00
Use set_lv() (wipe initial 4KiB) for non zeroed thin volume.
Allow cluster mirrors to handle the absence of the checkpoint lib (libSaCkpt). The OpenAIS checkpoint library is going away; therefore, cmirrord must operate without it. The algorithms the handle the timing of when to send a checkpoint, the determination of what to send, and which ongoing cluster requests are relevent with respect to the checkpoints are unaffected. We need only replace the functions that actually perform the storing/transmitting and retrieving/receiving of the checkpoint data. Rather than store the checkpoint data in an OpenAIS checkpoint file, we simply transmit it along with the message that notifies the incoming node that the checkpoint is ready.
2012-03-01 01:15:34 +04:00
Allow cluster mirrors to handle the absence of the checkpoint lib (libSaCkpt).
Revert free of allocated segtype lvm_register_segtype takes ownership of segtype and call destructor for it in error path.
2012-02-28 18:23:41 +04:00
Revert free of allocated segtype in init segment error path (2.02.89).
Test dm_hash_insert() failures mem failures

pre-release
2012-03-03 05:00:49 +04:00
Set stdin/stdout/stderr to /dev/null for polldaemon.
Limit max size of clvmd message This could be seen as some sort of simple validation - it's not easy to recognize a valid message for now - but we definitely do not want to allocate a lot of megabytes in clvmd memory locked daemon when broken message gets in. Size of 8000 is just selected for now - possibly there could be much lower value put in.
2012-02-28 13:58:19 +04:00
Limit the max size of processed clvmd message to ~8KB.
pre-release
2012-03-03 05:00:49 +04:00
Do not send uninitialised bytes in cluster error reply messages.
Use unsigned type for bitmask Using report_type_t for bitmask is not correct, since we have not defined types for all bit combinations - so switching to unsigned type, since values of report_type_t enum are unsigned.

Use unsigned type for bitmask instead of enum type for lvm properties.
Nicer cleanup of excl_uuid hash Since it on exit path, it's not a big difference, but makes less noise in analyzer and valgrind.

====================================
Require number of stripes to be greater than parity devices in higher RAID. Also, add some comments to code that I recently added that may be unclear otherwise.
2012-02-23 21:36:35 +04:00
Require number of stripes to be greater than parity devices in higher RAID.
Fix allocation code to allow replacement of single RAID 4/5/6 device. The code fail to account for the case where we just need a single device in a RAID 4/5/6 array. There is no good way to tell the allocation functions that we don't need parity devices when we are allocating just a single device. So, I've used a bit of a hack. If we are allocating an area_count that is <= the parity count, then we can assume we are simply allocating a replacement device (i.e. no need to include parity devices in the calculations). This should make sense in most cases. If we need to allocate replacement devices due to failure (or moving), we will never allocate more than the parity count; or we would cause the array to become unusable. If we are creating a new device, we should always create more stripes than parity devices.
2012-02-23 07:57:23 +04:00
Fix allocation code to allow replacement of single RAID 4/5/6 device.

2012-02-23 04:11:01 +04:00
Check all tags and LV names are in a valid form in vg_validate.
Add configure --with-tmpfilesdir and lvm2 tmpfiles.d configuration file itself. /etc/tmpfiles.d directory holds configuration files for temporary/volatile files and directories that should be automatically managed. For example, if we have some parts of the fs hierarchy on tmpfs, we'd like to recreate some files or directories on every boot so they're always prepared for use. Systemd can read such configuration files. For now, the lock and run directory are the ones that are most probably placed on tmpfs. If this is the case, we can install the configuration by 'make install_tmpfiles_configuration'.
2012-02-22 21:55:10 +04:00
Add tmpfiles.d style configuration for lvm2 lock and run directory.
Add configure --with-tmpfilesdir for dir holding volatile-file configuration.

Read dmeventd monitoring config settings for every lvm command.

Make conversion from a synced 'mirror' to 'raid1' not cause a full resync. It was not possible to pass down the DM_[FORCE|NO]SYNC flags to 'dm_tree_node_add_raid_target'. This meant that converting to 'raid1' from 'mirror' would cause a full resync. (It also meant that '--nosync' was ineffective when creating a 'raid1' LV.) I've taken the 'reserved' parameter in 'dm_tree_node_add_raid_target' and used it for the "flags" parameter. Now it is possible to pass the sync flags and any other flags that may come up.
2012-02-14 00:13:39 +04:00
Make conversion from a synced 'mirror' to 'raid1' not cause a full resync.

2012-02-08 15:34:46 +04:00
Use signed long for sysconf() call in cmirrord.
Move done jump lower Since before 'goto done' is bufused zeroed, it would otherwise write 1 byte in front of buffer.

Drop hack in segtype reporting Since striped name function knows when to report 'linear' instead of 'stripe' type name - drop it from this place. This fixes problem when reporting segtype e.g. for thin-pool which is also using area_count=1 to store thin data device reference. It also returns properly strduped memory instead of badly casted const char*.

Use new dmeventd_lvm2_command function in dmeventd plugins. For snapshot, prepare whole command in front into private buffer. Add also some missing '\n' for syslog messages. For raid and mirror only convert creation of command line string. This should avoid any unbound growth of mempool for dm_split_names.

Do not allow users to change the name of RAID sub-LVs independently.
Do not allow users to change permissions on RAID sub-LVs.
Allow lvconvert to replace specified devices in a RAID array.
Add activation/use_linear_target enabled by default. (prajnoha) LVM metadata knows only of striped segments - not linear ones. The activation code detects segments with a single stripe and switches them to use the linear target. If the new lvm.conf setting is set to 0 (e.g. in a test script), this 'optimisation' is turned off.
2011-11-29 00:37:51 +04:00
Add activation/use_linear_target enabled by default.
Cleanup test makefiles Simplify /api makefile and use SUBDIRS target for test dir. Properly cleanup Makefiles with distclean in /test. Use symbolic links for shell scripts for non-srcdir compilation.
2011-11-23 16:21:41 +04:00
Use gcc warning options only with .c to .o compilation.
Move y/n prompts to stderr and repeat if response has both 'n' and 'y'. (Note that in a future release we might make this stricter and insist on exactly 'y' or 'n'.)

2011-11-21 00:52:09 +04:00
Don't ignore configure --mandir and --infodir.
Drop pool memory allocated in lv_has_target_type Remove FIXMES - there should not be any pool free call since the memory pool is from device manager, and pool is detroyed after the operation, so doing extra free here would not help here. However lv_has_target_type() is using cmd mempool so here the extra call for dm_pool_free makes sence.
2011-11-18 23:42:03 +04:00
Drop pool memory allocated within lv_has_target_type().
Replace dynamic buffer allocations for PATH_MAX Use static buffer instead of stack allocated buffer. This reduces stack size usage of lvm tool and the change is very simple. Since the whole library is not thread safe - it should not add any new problems - and if there will be some conversion it's easy to convert this to use some preallocated buffer.
2011-11-18 23:31:09 +04:00
Reduce stack allocation of some PATH_MAX sized char buffers.
Unlock memory for vg_write For write we do not need to hold memory locked. This relaxes many conditions and avoid problems when allocating a lot of memory for writting metadata buffers. (In case of huge MDA size this would lead to mismatch between locked and unlocked memory region size). Add also internal check we are not writing in critical section.
2011-11-18 23:28:00 +04:00
Unlock memory before writing metadata.
Query before removing inactive snapshots Removal of an inactive origin removes also all related snapshots. When we now support 'old' external snapshots with thin volumes, removal of pool will not only drop all thin volumes, but as a consequence also all snapshots - which might be seen a bit unexpected for the user - so add a query to confirm such action. lvremove -f will skip the prompt.
2011-11-18 23:25:20 +04:00
Add query before removing snapshots when inactive snapshot origin is removed.

Do not scan device if it is part of active multipath. Add filter which tries to check if scanned device is part of active multipath. Firstly, only SCSI major number devices are handled in filter. Then it checks if device has exactly one holder (in sysfs) and if it is device-mapper device and DM-UUID is prefixed by "MPATH-". If so, this device is filtered out. The whole filter can be switched off by setting mpath_component_detection in lvm.conf. https://bugzilla.redhat.com/show_bug.cgi?id=597010 Signed-off-by: Milan Broz <mbroz@redhat.com>

Avoid recursive calls to dmeventd in its LVM plugins.
cmirrord now returns log name to kernel in CTR so it can be registered Version 2 of the userspace log protocol accepts return information during the DM_ULOG_CTR exchange. The return information contains the name of the log device that is being used (if there is one). The kernel can then register the device via 'dm_get_device'. Amoung other things, this allows for userspace to assemble a correct dependency tree of devices - critical for LVM handling of suspend/resume calls. Also, update dm-log-userspace.h to match the kernel header associated with this protocol change. (Includes a version inc.)

Add the ability to convert LVs of "mirror" segtype to "raid1" segtype. Example: ~> lvconvert --type raid1 vg/mirror_lv Steps to convert "mirror" to "raid1" 1) Allocate a RAID metadata LV for each mirror image from the same PVs on which they are located. 2) Clear the metadata LVs. This involves writing LVM metadata, so we don't change any aspects of the mirror LV before this so that the user can easily remove LVs from the failed convert attempt while retaining the original mirror. 3) Remove the mirror log, if it exists. 4) Add metadata LVs to mirror LV 5) Rename mirror sub-lvs (s/mimage/rimage/) 6) Change flags and segtype from mirror to raid1
2011-10-07 18:56:01 +04:00
Add ability to convert mirror segtype to RAID1 segtype.
Add the ability to convert linear LVs to RAID1 Example: ~> lvconvert --type raid1 -m 1 vg/lv The following steps are performed to convert linear to RAID1: 1) Allocate a metadata device from the same PV as the linear device to provide the metadata/data LV pair required for all RAID components. 2) Allocate the required number of metadata/data LV pairs for the remaining additional images. 3) Clear the metadata LVs. This performs a LVM metadata update. 4) Create the top-level RAID LV and add the component devices. We want to make any failure easy to unwind. This is why we don't create the top-level LV and add the components until the last step. Should anything happen before that, the user could simply remove the unnecessary images. Also, we want to ensure that the metadata LVs are cleared before forming the array to prevent stale information from polluting the new array. A new macro 'seg_is_linear' was added to allow us to distinguish linear LVs from striped LVs.
2011-10-07 18:52:26 +04:00
Add ability to convert from linear to RAID1.
Allow 'nosync' extension of mirrors. This patch allows a mirror to be extended without an initial resync of the extended portion. It compliments the existing '--nosync' option to lvcreate. This action can be done implicitly if the mirror was created with the '--nosync' option, or explicitly if the '--nosync' option is used when extending the device. Here are the operational criteria: 1) A mirror created with '--nosync' should extend with 'nosync' implicitly [EXAMPLE]# lvs vg; lvextend -L +5G vg/lv ; lvs vg LV VG Attr LSize Pool Origin Snap% Move Log Copy% Convert lv vg Mwi-a-m- 5.00g lv_mlog 100.00 Extending 2 mirror images. Extending logical volume lv to 10.00 GiB Logical volume lv successfully resized LV VG Attr LSize Pool Origin Snap% Move Log Copy% Convert lv vg Mwi-a-m- 10.00g lv_mlog 100.00 2) The 'M' attribute ('M' signifies a mirror created with '--nosync', while 'm' signifies a mirror created w/o '--nosync') must be preserved when extending a mirror created with '--nosync'. See #1 for example of 'M' attribute. 3) A mirror created without '--nosync' should extend with 'nosync' only when '--nosync' is explicitly used when extending. [EXAMPLE]# lvs vg; lvextend -L +5G vg/lv; lvs vg LV VG Attr LSize Pool Origin Snap% Move Log Copy% Convert lv vg mwi-a-m- 20.00m lv_mlog 100.00 Extending 2 mirror images. Extending logical volume lv to 5.02 GiB Logical volume lv successfully resized LV VG Attr LSize Pool Origin Snap% Move Log Copy% Convert lv vg mwi-a-m- 5.02g lv_mlog 0.39 vs. [EXAMPLE]# lvs vg; lvextend -L +5G vg/lv --nosync; lvs vg LV VG Attr LSize Pool Origin Snap% Move Log Copy% Convert lv vg mwi-a-m- 20.00m lv_mlog 100.00 Extending 2 mirror images. Extending logical volume lv to 5.02 GiB Logical volume lv successfully resized LV VG Attr LSize Pool Origin Snap% Move Log Copy% Convert lv vg Mwi-a-m- 5.02g lv_mlog 100.00 4) The 'm' attribute must change to 'M' when extending a mirror created without '--nosync' is extended with the '--nosync' option. (See #3 examples above.) 5) An inactive mirror's sync percent cannot be determined definitively, so it must not be allowed to skip resync. Instead, the extend should ask the user if they want to extend while performing a resync. [EXAMPLE]# lvchange -an vg/lv [EXAMPLE]# lvextend -L +5G vg/lv Extending 2 mirror images. Extending logical volume lv to 10.00 GiB vg/lv is not active. Unable to get sync percent. Do full resync of extended portion of vg/lv? [y/n]: y Logical volume lv successfully resized 6) A mirror that is performing recovery (as opposed to an initial sync) - like after a failure - is not allowed to extend with either an implicit or explicit nosync option. [You can simulate this with a 'corelog' mirror because when it is reactivated, it must be recovered every time.] [EXAMPLE]# lvcreate -m1 -L 5G -n lv vg --nosync --corelog WARNING: New mirror won't be synchronised. Don't read what you didn't write! Logical volume "lv" created [EXAMPLE]# lvs vg LV VG Attr LSize Pool Origin Snap% Move Log Copy% Convert lv vg Mwi-a-m- 5.00g 100.00 [EXAMPLE]# lvchange -an vg/lv; lvchange -ay vg/lv; lvs vg LV VG Attr LSize Pool Origin Snap% Move Log Copy% Convert lv vg Mwi-a-m- 5.00g 0.08 [EXAMPLE]# lvextend -L +5G vg/lv Extending 2 mirror images. Extending logical volume lv to 10.00 GiB vg/lv cannot be extended while it is recovering. 7) If 'no' is selected in #5 or if the condition in #6 is hit, it should not result in the mirror being resized or the 'm/M' attribute being changed. NOTE: A mirror created with '--nosync' behaves differently than one created without it when performing an extension. The former cannot be extended when the mirror is recovering (unless in-active), while the latter can. This is a reasonable thing to do since recovery of a mirror doesn't take long (at least in the case of an on-disk log) and it would cause far more time in degraded mode if the extension w/o '--nosync' was allowed. It might be reasonable to add the ability to force the operation in the future. This should /not/ force a nosync extension, but rather force a sync'ed extension. IOW, the user would be saying, "Yes, yes... I know recovery won't take long and that I'll be adding significantly to the time spent in degraded mode, but I need the extra space right now!".

Use execvp for clvmd restart Since execve passed only NULL as environ, we had lost all environment vars on restart - thus actually running 'different' clvmd then the one at start. Preserving environ allows to restart clvmd with the same settings (i.e. LD_LIBRARY_PATH) Add test for second restart.

CLVMD bugfix support for args -S -E Bugfix: Add (most probably unfinished) support for -E arg with list of exclusive locks. (During clvmd restart all exclusive locks would have been lost and in fact, if there would have been an exclusive lock, usage text would be printed and clvmd exits.) Instead of parsing list options multiple times every time some lock UUID is checked - put them straight into the hash table - make the code easier to understand as well. Remove was_ex_lock() function (replaced with dm_hash_lookup()). Swap return value for get_initial_state() (1 means success). Update man pages and usage info for -E option.

Replace open_count check with holders/mounted_fs check on lvremove path. Before, we used to display "Can't remove open logical volume" which was generic. There 3 possibilities of how a device could be opened: - used by another device - having a filesystem on that device which is mounted - opened directly by an application With the help of sysfs info, we can distinguish the first two situations. The third one will be subject to "remove retry" logic - if it's opened quickly (e.g. a parallel scan from within a udev rule run), this will finish quickly and we can remove it once it has finished. If it's a legitimate application that keeps the device opened, we'll do our best to remove the device, but we will fail finally after a few retries.
2011-09-22 21:33:50 +04:00
Replace open_count check with holders/mounted_fs check on lvremove path.
Disallow the creation of mirrors (mirror or raid1 segtype) with only one leg. If you specify the segment type (e.g. --type mirror) and the mirrors argument as zero, it would result in a mirrored LV with only one image. While the device may be valid in theory, it should not be allowed in practice. It also makes it difficult on the conversion tools, since they react badly to single-image mirrors.
2011-09-22 19:36:21 +04:00
Disallow the creation of mirrors (mirror or raid1 segtype) with only one leg.
Clvmd restart cleanup Patch fixes Clang warnings about possible access via lv_name NULL pointer. Replaces allocation of memory (strdup) with just pointer assignment (since execve is being called anyway). Checks for !*lv_name only when lv_name is defined. (and as I'm not quite sure what state this really is - putting a FIXME around - as this rather looks suspicios ??). Add debug print of passed clvmd args.

Check for failing 'stat' and skip this loop iteration (since data in statbuf are invalid). Check whether sysconf managed to find _SC_PAGESIZE. Report at least debug warning about failing unlink (logging scheme here seems to be a different then in lvm). Duplicate terminal FDs and use similar code as is made in clvmd and cleanup warns about missing open/close tests. FIXME: Looks like we already have 3 instancies of the same code in lvm repo.

Add support for DM_DEV_DIR device path into fsadm script.
Support different PATH setting When fsadm is test - it needs to execute lvm and fsadm from non-standard path setting. So adding a support in fsadm script when user set LVM_BINARY, then the lvm command invoced from fsadm will have the same PATH setting as before entering fsadm command. Needed for testing.
2011-09-19 17:51:09 +04:00

Fix for bug 734252 - problem up converting striped mirror after image failure lv_mirror_count was not able to handle mirrors of stripes properly. When a failed device is removed, the MIRRORED status flag is removed from the LV conditionally based on the results of lv_mirror_count. However, lv_mirror_count trusted the MIRRORED flag - thinking any such LV must be mirrored. It would happily assign first_seg(lv)->area_count as the number of mirrors, but when a mirrored striped LV was reduced to a simple striped LV area_count would be the number of /stripes/ not the number of /mirrors/. A result higher than 1 would be returned from lv_mirror_count, the MIRRORED flag would not be cleared, and the LV would fail to be up-converted properly in lvconvert_mirrors_aux because of it.
2011-09-14 06:45:36 +04:00
Fix lv_mirror_count to handle mirrored stripes properly.
Fix bug 733400 - Mirror down conversion when specifying the secondary leg is broke The operation of deactivating the residual error target LV after removing a mirror layer can cause a "device in-use" conflict with udev. Giving udev a poke before calling deactivate_lv eliminates the conflict. The stick used to poke udev is 'sync_local_dev_names'.

Fix mirrored log creation when PE size is small: use log_size >= region_size.
Fix for bug 737125 - unable to create mirror on 1K extent size VG _alloc_init calculates the number of necessary log extents via 'mirror_log_extents'. 'mirror_log_extents' takes 3 arguments: region_size, pe_size, and size of the mirror LV. Unfortunately, _alloc_init is guessing at the mirror size by using 'ah->new_extents / ah->area_multiple' - the number of extents that the mirror images have. However, this is /always/ wrong when allocating the log separately. Further, the log is always allocated separately unless we are up-converting the mirror at the same time. It was by luck alone that a default value of '1' reflects what we want in most cases. In order to get a decent value computed, we need to pass in the 'lv' argument to allocate_extents. This would normally imply a desire for cling/contiguous allocation to the given LV, but since we are not allocating any parallel extents and only log extents, it works fine.

Switch int to unsigned type for pvmetadatacopies for pv_create().
Replace char class :space: with explicit chars Some major distributions are still using 'mawk' and they are not using the latest version - we end here with hidden dependency on the latest version of mawk (1.3.4) while i.e. Debian Lenny seems to stay with 1.3.3. So we end with completely broken vgimportclone script on such system. We would need to check for proper support of :space: and abort build if it doesn't work or simplier replace [:space:] with [ \t] which seems sufficient to make it work (as can be seen in this patch) A better fix would be to use command line parameter override - leaving as FIXME comment. This patch makes t-vgimportclone.sh test passing on Lenny.
2011-09-07 12:31:16 +04:00
Replace :space: with [\t ] for awk in vgimportclone (not widely supported).

Fix for bug 732142: Unsafe table load during mirror image split There was a bad sequence: *) Make changes to LV layout to split images (e.g. 4-way -> 2-way/2-way) 1) vg_write, suspend_lv(original_mirror), vg_commit 2) activate_lv(newly_split_lv) 3) resume_lv(original_mirror) Step #2 is not allowed. However, without it, the resume of the original mirror will also resume its former sub-LVs - making it impossible to activate the newly split LV due to the changes in layering, pointers, and names that had already been made. Additionally, the resume or the original brings the sub-lv's online with names that differ from the metadata on disk - also a no-no. Thus, the split must be done in stages such that the active LVs always reflect what is in the committed LVM metadata. First, alter the original mirror by releasing the images. The images are made visible and independent as an intermediate stage. (This way, we can have consistency between LVM metadata and active LVs.) The second stage collects the recently split LVs, deactivates them, forms them into a mirror if necessary, and then activates them. It is a bit of a circuitous method, but it is the only way to split a mirror from a mirror and obey these general rules: 1) Never [de]activate sub-lvs when the top-level LV is suspended 2) Avoid having active LVs that differ from the description in the LVM metadata Signed-off-by: Jonathan Brassow <jbrassow@redhat.com>

Update for resource leak
2011-08-31 12:23:33 +04:00
Fix resource leak when strdup fails in _get_device_status() (2.02.85).
Directly allocate buffer memory in a pvck scan instead of using a mempool. There's a very high memory usage when calling _pv_analyse_mda_raw (e.g. while executing pvck) that can end up with "out of memory". _pv_analyse_mda_raw scans for metadata in the MDA, iteratively increasing the size to scan with SECTOR_SIZE until we find a probable config section or we're at the edge of the metadata area. However, when using a memory pool, we're also iteratively chasing for bigger and bigger mempool chunk which can't be found and so we're always allocating a new one, consuming more and more memory... This patch just changes the mempool to direct memory allocation in this problematic part of the code.

Add global/detect_internal_vg_cache_corruption to lvm.conf.
Lock memory for shared VG Use debug pool locking functionality. So the command could check, whether the memory in the pool has not been modified. For lv_postoder() instead of unlocking and locking for every changed struct status member do it once when entering and leaving function. (mprotect would trap each such memory access). Currently lv_postoder() does not modify other part of vg structure then status flags of each LV with flags that are reverted back to its original state after function exit.
2011-08-11 21:34:30 +04:00
Use memory pool locking to check for corruption of internal VG structs.
Cache and share generated VG structs Extend vginfo cache with cached VG structure. So if the same metadata are use, skip mda decoding in the case, the same data are in use. This helps for operations like activation of all LVs in one VG, where same data were decoded giving the same output result. Patch adds 1-to-1 connection between volume_group and lvmcache_vginfo.

Replace free_vg with release_vg and move it to vg.c.
Remove INCONSISTENT_VG flag As this flag could not have been set by the current code - removing it. Note: because of the wrong code logic this call: lvmcache_update_vg(correct_vg, correct_vg->status & PRECOMMITTED & (inconsistent ? INCONSISTENT_VG : 0)); had always passed '0' - now after flag removal it's passing PRECOMMITTED flag in - this present functinal change in this patch. To match the original functionality - 0 had to be always passed. More testing is needed here.

Suppress low-level locking errors and warnings while using --sysinit. Today, we use "suppress_messages" flag (set internally in init_locking fn based on 'ignorelockingfailure() && getenv("LVM_SUPPRESS_LOCKING_FAILURE_MESSAGES")'. This way, we can suppress high level messages like "File-based locking initialisation failed" or "Internal cluster locking initialisation failed". However, each locking has its own sequence of initialization steps and these could log some errors as well. It's quite misleading for the user to see such errors and warnings if the "--sysinit" is used (and so the ignorelockingfailure && LVM_SUPPRESS_LOCKING_FAILURE_MESSAGES environment variable). Errors and warnings from these intermediary steps should be suppressed as well if requested. This patch propagates the "suppress_messages" flag deeper into locking init functions. I've also added these flags for other locking types for consistency, though it's not actually used for no_locking and readonly_locking.
2011-08-09 15:44:57 +04:00
Suppress low-level locking errors and warnings while using --sysinit.

Code move of vg_mark_partial() up in stack It's useful to keep the partial flag cached - so just move the call for vg_mark_partil_lvs() into import_vg_from_config_tree() so it gets evaluated before it goes through the lvmcache. This patch should not present any functional change. Note: It is rather temporal solution - proper place is probably inside the 'read' call back - but needs some more discussion. For now using this minor hack.

Call vg_mark_partial_lvs() before VG structure is returned from the cache.

Add proper udev library context initialization and finalization to liblvm. This was missing in liblvm and it caused all udev-related operations to not take effect when using liblvm, e.g. obtaining the list of devices from udev db instead of scanning the whole /dev which also recreated the .cache as a side effect. This was also the case with udisks-lvm-pv-export prober which is run from within udev rules whenever the CHANGE event is fired.

Maintain a count of the number of suspended devices in libdevmapper and use this for the LVM critical section logic. Also report an error if code tries to load a table while any device is known to be in the suspended state. (If the variety of problems these changes are showing up can't be fixed before the next release, the error messages can be reduced to debug level.)

Major pvmove fix to issue ioctls in the correct order when multiple LVs are affected by the move. (Currently it's possible for I/O to become trapped between suspended devices amongst other problems. The current fix was selected so as to minimise the testing surface. I hope eventually to replace it with a cleaner one that extends the deptree code. Some lvconvert scenarios still suffer from related problems.

Fix create_temp_name to replace any '/' found in the hostname with '?'. There's a possibility someone will use the '/' in the hostname. Since we generate a temporary file name (path) including the hostname, any '/' would be ambiguous. We can always set such hostname using 'sethostname' from unistd.h. But the 'hostname' command already includes the check and removes the '/' char. However, some old versions still allow that. See: https://bugzilla.redhat.com/show_bug.cgi?id=711445. Since this is only a temporary name and the possibility of this error is quite negligible, we don't need any complex escape sequence here, just a simple char replace.

Version 2.02.85 - 29th April 2011
=================================
Obtain device list from udev by default if LVM2 is compiled with udev support. Also, add a new 'obtain_device_list_from_udev' setting to lvm.conf with which we can turn this feature on or off if needed. If set, the cache of block device nodes with all associated symlinks will be constructed out of the existing udev database content. This avoids using and opening any inapplicable non-block devices or subdirectories found in the device directory. This setting is applied to udev-managed device directory only, other directories will be scanned fully. LVM2 needs to be compiled with udev support for this setting to take effect. N.B. Any device node or symlink not managed by udev in udev directory will be ignored with this setting on.

Fix reading of unitialized memory Could be reached via few of our lvm2 test cases: ==11501== Invalid read of size 8 ==11501== at 0x49B2E0: _area_length (import-extents.c:204) ==11501== by 0x49B40C: _read_linear (import-extents.c:222) ==11501== by 0x49B952: _build_segments (import-extents.c:323) ==11501== by 0x49B9A0: _build_all_segments (import-extents.c:334) ==11501== by 0x49BB4C: import_extents (import-extents.c:364) ==11501== by 0x497655: _format1_vg_read (format1.c:217) ==11501== by 0x47E43E: _vg_read (metadata.c:2901) cut from t-vgcvgbackup-usage.sh -- pvcreate -M1 $(cat DEVICES) vgcreate -M1 -c n $vg $(cat DEVICES) lvcreate -l1 -n $lv1 $vg $dev1 -- Idea of the fix is rather defensive - to allocate one extra element to 'map' array which is then used in _area_length() - where the loop checks, whether next map entry is continuous. By placing there always one extra zero entry - we fix the read of unallocated memory, and we make sure the data would not make a continous block. FIXME: there could be a problem if some special broken lvm1 data would be imported. As the format1 is currently not really used - leave it for future fix and use this small hotfix for now.
2011-03-30 16:30:39 +04:00

Replace several strncmp() calls with id_equal().
Fix access to released memory Invalid primary_vginfo was supposed to move all its lvmcache_infos to orphan_vginfo - however it has called _drop_vginfo() inside the loop that released primary_vginfo itself - thus made the loop using released memory. Use _vginfo_detach_info() instead and call _drop_vginfo after th loop is finished. Valgrind trace it should fix: Invalid read of size 8 at 0x41E960: _lvmcache_update_vgname (lvmcache.c:1229) by 0x41EF86: lvmcache_update_vgname_and_id (lvmcache.c:1360) by 0x441393: _text_read (text_label.c:329) by 0x442221: label_read (label.c:289) by 0x41CF92: lvmcache_label_scan (lvmcache.c:635) by 0x45B303: _vg_read_by_vgid (metadata.c:3342) by 0x45B4A6: lv_from_lvid (metadata.c:3381) by 0x41B555: lv_activation_filter (activate.c:1346) by 0x415868: do_activate_lv (lvm-functions.c:343) by 0x415E8C: do_lock_lv (lvm-functions.c:532) by 0x40FD5F: do_command (clvmd-command.c:120) by 0x413D7B: process_local_command (clvmd.c:1686) Address 0x63eba10 is 16 bytes inside a block of size 160 free'd at 0x4C2756E: free (vg_replace_malloc.c:366) by 0x41DE70: _free_vginfo (lvmcache.c:980) by 0x41DEDA: _drop_vginfo (lvmcache.c:998) by 0x41E854: _lvmcache_update_vgname (lvmcache.c:1238) by 0x41EF86: lvmcache_update_vgname_and_id (lvmcache.c:1360) by 0x441393: _text_read (text_label.c:329) by 0x442221: label_read (label.c:289) by 0x41CF92: lvmcache_label_scan (lvmcache.c:635) by 0x45B303: _vg_read_by_vgid (metadata.c:3342) by 0x45B4A6: lv_from_lvid (metadata.c:3381) by 0x41B555: lv_activation_filter (activate.c:1346) by 0x415868: do_activate_lv (lvm-functions.c:343) problematic line: dm_list_iterate_items_safe(info2, info3, &primary_vginfo->infos)

Fix allocation of system_id As code uses strncpy(system_id, NAME_LEN) and doesn't set '\0' Fix it by always allocating NAME_LEN + 1 buffer size and with zalloc we always get '\0' as the last byte. This bug may trigger some unexpected behavior of the string operation code - depends on the pool allocator. FIXME: refactor this code to alloc_vg.

Use format instance mempool where possible and adequate.
Call destroy_instance for any PVs found in VG structure during vg_free call. This is necessary for proper format instance ref_count support. We iterate over vg->pvs and vg->removed_pvs list and the ref_count is decremented and then it is destroyed if not referenced anymore.
2011-03-11 18:06:13 +03:00
Call destroy_instance for any PVs found in VG structure during vg_free call.
Add new free_pv_fid fn and use it throughout to free all attached fids. Since format instances will use own memory pool, it's necessary to properly deallocate it. For now, only fid is deallocated. The PV structure itself still uses cmd mempool mostly, but anytime we'd like to add a mempool in the struct physical_volume, we can just rename this fn to free_pv and add the code (like we have free_vg fn for VGs).
2011-03-11 17:56:56 +03:00
Add new free_pv_fid fn and use it throughout to free all attached fids.
Use only vg_set_fid and new pv_set_fid fn to assign the format instance. This is essential for proper format instance ref_count support. We must use these functions to set the fid everywhere from now on, even the NULL value!
2011-03-11 17:50:13 +03:00
Use only vg_set_fid and new pv_set_fid fn to assign the format instance.
Make create_text_context fn static and move it inside create_instance fn. We'd like to use the fid mempool for text_context that is stored in the instance (we used cmd mempool before, so the order of initialisation was not a matter, but now it is since we need to create the fid mempool first which happens in create_instance fn). The text_context initialisation is not needed anywhere outside the create_instance fn so move it there.
2011-03-11 17:45:17 +03:00
Make create_text_context fn static and move it inside create_instance fn.
Add mem and ref_count fields to struct format_instance for own mempool use. Format instances can be created anytime on demand and it contains metadata area information mostly (at least for now, but in the future, we may store more things here to update/edit in a PV/VG). In case we have lots of metadata areas, memory consumption will rise. Using cmd context mempool is not quite optimal here because it is destroyed too late. So let's use a separate mempool for format instances. Reference counting is used because fids could be shared, e.g. each PV has either a PV-based fid or VG-based fid. If it's VG-based, each PV has a shared fid with the VG - a reference to VG's fid.
2011-03-11 17:38:38 +03:00
Add mem and ref_count fields to struct format_instance for own mempool use.

2011-03-11 17:30:27 +03:00
Use new alloc_fid fn for common format instance initialisation.
Optimise _eat_space and _get_token Makes the code more readable and has a smaller number of memory accesses thus it's small optimisation as well. For _get_token() optimize number parsing. Check for '.' char only if it's not a digit. Move pointer incrementation into one place. For _eat_space() check only p->te for '\0' in skipping of comment line. Avoid check for '\0' when we know it is space. Also master while loop doesn't need checking p->tb for '\0'. We just need to check p->tb isn't already at the end of buffer. This could give 'extra' loop cycle if we are already there - but safes memory access in every other case.
2011-03-10 17:51:35 +03:00
Optimise _get_token() and _eat_space().
Refactor code for _lv_postoder Add _lv_postorder_vg() - for calling _lv_postorder() for every LV from VG. We use this in 2 places - vg_mark_partial_lvs() and vg_validate() so make it as a one function. Benefit here is - to use only one cleanup code and avoid potentially duplicate scans of same LVs.
2011-03-10 17:40:32 +03:00

Allow non-orphan PVs with two metadata areas to be resized. We allow writing non-orphan PVs only for resize now. The "orphan PV" assert in pv_write fn uses the "allow_non_orphan" parameter to control this assert. However, we should find a more elaborate solution so we can remove this restriction altogether (pv_write together with vg_write is not atomic, we need to find a safe mechanism so there's an easy revert possible in case of an error).

2011-01-25 02:34:46 +03:00
===================================
Allow snapshots in a cluster as long as they are exclusively activated. In order to achieve this, we need to be able to query whether the origin is active exclusively (a condition of being able to add an exclusive snapshot). Once we are able to query the exclusive activation of an LV, we can safely create/activate the snapshot. A change to 'hold_lock' was also made so that a request to aquire a WRITE lock did not replace an EX lock, which is already a form of write lock.
2011-02-04 23:30:17 +03:00

Fix udev synchronization for no-locking mode Instead of implicitly syncing udev operation in clustered and file locking code - call synchronization directly in lock_vol() when the operation unlocks VG The problem is missing implicit fs_unlock() in the no_locking code. This is used with --sysinit on read-only filesystem locking dir. In this case vgchange -ay could exit before all udev nodes are properly synchronised and may cause problems with accessing such node right after vgchange --sysinint command is finished. Add test case for vgchange --sysinit.

Enhance vg_validate to ensure integrity of LV and PV structs referenced.
Enhance vg_validate to check composition of pvmove LVs.
Create /var/run/lvm directory during clvmd initialisation if missing. We need to be sure that /var/run and /var/lock is always there. (E.g. these two directories could be using tmpfs which then loose all the content after reboot.)
2010-12-13 13:49:02 +03:00
Create /var/run/lvm directory during clvmd initialisation if missing.
Add new dm_prepare_selinux_context fn to libdevmapper and use it throughout. Detect existence of new SELinux selabel interface during configure. Use new dm_prepare_selinux_context instead of dm_set_selinux_context. We should set the SELinux context before the actual file system object creation. The new dm_prepare_selinux_context function sets this using the selabel_lookup fn in conjuction with the setfscreatecon fn. If selinux/label.h interface (that should be a part of the selinux library) is not found during configure, we fallback to the original matchpathcon function instead.
2010-12-13 13:43:56 +03:00
Use new dm_prepare_selinux_context instead of dm_set_selinux_context.
Fix scanning of VGs without in-PV mdas. Set cmd->independent_metadata_areas if metadata/dirs or disk_areas in use. - Identify and record this state. Don't skip full scan when independent mdas are present even if memlock is set. - Clusters and OOM aren't supported, so no problem doing the proper scans. Avoid revalidating the label cache immediately after scanning. - A simple optimisation. Support scanning for a single VG in independent mdas. - Not used by the fix but I left it in anyway as later patches might use it.

Use new status code from fsadm check Patch updates exec_cmd() and adds 3rd parameter with pointer for status value, so caller might examine returned status code. If the passed pointer is NULL, behavior is unmodified. Patch allows to confinue with lvresize if the failure from fsadm check is caused by mounted filesystem as many of filesystem resize tools do support online filesystem resize. (originally user had to use flag '-n' to bypass this filesystem check)

Remove dependency on libm by replacing floor() by an integer-based algorithm.
Fix for bug 637936: killing both redundant logs causes deadlock Problem: When both legs of a mirrored log fail, neither the log nor the parent mirror can proceed. The repair code must be careful to replace the log with an error target before operating on the parent - otherwise, the parent can get stuck trying to suspend because it can't push through any writes. The steps to replace the log device with an error target were incomplete and resulted in the replacement not happening at all! The code originally had all the necessary logic to complete the replacement task, but was pulled out in a effort to clean-up that section of code, while fixing another bug: <offending commit msg> In addition, I added following three changes. - Removed tmp_orphan_lvs handling procedure It seems that _delete_lv() can handle detached_log_lv properly without adding mirror legs in mirrored log to tmp_orphan_lvs. Therefore, I removed the procedure. - Removed vg_write()/vg_commit() Metadata is saved by vg_write()/vg_commit() just after detached_log_lv is handled. Therefore, I removed vg_write()/vg_commit(). </offending commit msg> http://sources.redhat.com/cgi-bin/cvsweb.cgi/LVM2/lib/metadata/mirror.c?cvsroot=lvm2&f=h#rev1.130 I've reverted the "clean-up" changes associated with that fix, but not what that commit was actually fixing.

Fix detection of mounted filesystem. Update the way how fsadm detects mounted filesystem. With udev /dev/dm-XXX paths are now returned - but mount or /proc/mounts prints names in form of /dev/mapper/vg-lv - so the match was not found. Fixex RHBZ #638050. Current solution uses same trick as mount and detects vg-lv name through /sys where available - this should be reasonable safe. Instead of calling mount without parameter to get actual mount table, switch to use /proc/mounts directly.

Rename 'flags' to 'status' for struct metadata_area. In other LVM memory structures such as volume_group, the field used to store flags is called "status", and on-disk fields are called 'flags', so rename the one inside metadata_area to be consistent. Not only is it more consistent with existing code but is cleaner to say "the status of this mda is ignored". Background for this patch - prajnoha pinged me on IRC this morning about a fix he was working on related to metadataignore when metadata/dirs was set. I was reviewing my patches from this year and realized the 'flags' field was probably not the best choice when I originally did the metadataignore patches.

Restrict lvm1 partial mode. Current lvm1 allocation code seems to not properly map segments on missing PVs. For now disable this functionality.

Also do not use random PV UUID for missing part but use fixed string derived from VG UUID (to not confuse clvmd tests).

Add random suffix to archive file names to prevent races when being created. In certain configurations, we're not under a VG rw lock while trying to write a new archive file with VG metadata. A common example is using "vgs" while having the content of backup and archive directories empty. The code scans the content of these directories and tries to determine the final index that should be used in archive name. Since we're not under a lock, we can get into a race while choosing the index which could end up showing errors about not being able to rename to final archive name. Let's add random number suffix to these archive file names so we can avoid the race.

This patch fixes a problem where the mirror polling process may never complete. If you convert from a linear to a mirror and then convert that mirror back to linear /while/ the previous (up)convert is taking place, the mirror polling process will never complete. This is because the function that polls the mirror for completion doesn't check if it is still polling a mirror and the copy_percent that it gets back from the linear device is certainly never 100%. The fix is simply to check if the daemon is still looking at a mirror device - if not, return PROGRESS_CHECK_FAILED. The user sees the following output from the first (up)convert if someone else sneaks in and does a down-convert shortly after their convert: [root@bp-01 ~]# lvconvert -m1 vg/lv vg/lv: Converted: 43.4% ABORTING: Mirror percentage check failed.
2010-08-26 20:29:12 +04:00
Make poll_mirror_progress report PROGRESS_CHECK_FAILED if LV is not a mirror.
This patch fixes a potential for I/O to hang and LVM commands to block when a mirror under a snapshot suffers a failure. The problem has to do with label scanning. When a mirror suffers a failure, the kernel blocks I/O to prevent corruption. When LVM attempts to repair the mirror, it scans the devices on the system for LVM labels. While mirrors are skipped during this scanning process, snapshot-origins are not. When the origin is scanned, it kicks up I/O to the mirror (which is blocked) underneath - causing the label scan (an thus the repair operation) to hang. This patch simply bypasses snapshot-origin devices when doing labels scans (while ignore_suspended_devices() is set). This fixes the issue.
2010-08-26 18:21:50 +04:00
Like mirrors, don't scan origins if ignore_suspended_devices() is set.

This means the md_chunk_alignment and data_alignment_detection are disabled if set. (Same now applies to pvcreate --dataalignmentoffset, the specified value will be used instead of the result from data_alignment_offset_detection) set_pe_align() still looks to use the determined default alignment (based on lvm.conf's default_data_alignment) if the default is a multiple of the MD or topology detected values.

Version 2.02.73 - 18th August 2010
==================================
Fix for bug 596453: multiple mirror image failures cause lvm repair... The lvm repair issues I believe are the superficial symptoms of this bug - there are worse issues that are not as clearly seen. From my inline comments: * If the mirror was successfully recovered, we want to always * force every machine to write to all devices - otherwise, * corruption will occur. Here's how: * Node1 suffers a failure and marks a region out-of-sync * Node2 attempts a write, gets by is_remote_recovering, * and queries the sync status of the region - finding * it out-of-sync. * Node2 thinks the write should be a nosync write, but it * hasn't suffered the drive failure that Node1 has yet. * It then issues a generic_make_request directly to * the primary image only - which is exactly the device * that has suffered the failure. * Node2 suffers a lost write - which completely bypasses the * mirror layer because it had gone through generic_m_r. * The file system will likely explode at this point due to * I/O errors. If it wasn't the primary that failed, it is * easily possible in this case to issue writes to just one * of the remaining images - also leaving the mirror inconsistent. * * We let in_sync() return 1 in a cluster regardless of what is * in the bitmap once recovery has successfully completed on a * mirror. This ensures the mirroring code will continue to * attempt to write to all mirror images. The worst that can * happen for reads is that additional read attempts may be * taken.

Fix for bug 612291: dm devices of split off mirror images are not removed DM devices were not handled properly on nodes in a cluster that were not where the splitmirrors command was issued. This was happening because suspend_lv/resume_lv were being used in a place where activate_lv should have been used. When the suspend/resume are issued on (effectively) new LVs, their 'resource' (UUID) is not located in the lv_hash. Thus, both operations turn into no-ops. You can see this from the output of clvmd from one of the remote nodes: <snip> do_suspend_lv, lock not already held <snip> do_resume_lv, lock not already held 'activate_lv' enjoins the other nodes in the cluster to process the lock and activate the new LV. clvmd output from remote node as follows: do_lock_lv: resource 'zMseY7CBuO3Ty09vXlplPAHzD0Y0CovjrTdv0R1VcwggMwPdYhutHErRcwm5Nd2S', cmd = 0x19 LCK_LV_ACTIVATE (READ|LV|NONBLOCK), flags = 0x84 (DMEVENTD_MONITOR ), memlock = 1 sync_lock: 'zMseY7CBuO3Ty09vXlplPAHzD0Y0CovjrTdv0R1VcwggMwPdYhutHErRcwm5Nd2S' mode:1 flags=1 sync_lock: returning lkid 27b0001 Signed-off-by: Jonathan Brassow <jbrassow@redhat.com> Reviewed-by: Petr Rockai <prockai@redhat.com>

Change default alignment of pe_start to 1MB. The new standard in the storage industry is to default alignment of data areas to 1MB. fdisk, parted, and mdadm have all been updated to this default. Update LVM to align the PV's data area start (pe_start) to 1MB. This provides a more useful default than the previous default of 64K (which generally ended up being a 192K pe_start once the first metadata area was created). Before this patch: # pvs -o name,vg_mda_size,pe_start PV VMdaSize 1st PE /dev/sdd 188.00k 192.00k After this patch: # pvs -o name,vg_mda_size,pe_start PV VMdaSize 1st PE /dev/sdd 1020.00k 1.00m The heuristic for setting the default alignment for LVM data areas is: - If the default value (1MB) is a multiple of the detected alignment then just use the default. - Otherwise, use the detected value. In practice this means we'll almost always use 1MB -- that is unless: - the alignment was explicitly specified with --dataalignment - or MD's full stripe width, or the {minimum,optimal}_io_size exceeds 1MB - or the specified/detected value is not a power-of-2

Don't ignore user-specified PVs in split-mirror operations. (2.02.71)
A misunderstanding of the return value of 'dm_bit' has been causing a data corruption bug in cmirror. 'dm_bit' is only ever used as a boolean operation within LVM, but it can return a range of values. If the bit is set, a power of 2 is returned. If the bit is unset, 0 is returned. 'log_test_bit' (a function in the cluster mirror log daemon code) has switched to using the dm bit operations in rhel6. There are two places in the daemon code where 'log_test_bit' is not used merely as a boolean, but rather the return value is used as the return value for the log functions 'is_clean' and 'in_sync' - having assumed that 'dm_bit' was returning 0 or 1 only. One place the 'in_sync' function is utilized is in 'dm_rh_get_state' - a function that informs the mirroring code how to treat I/O and which devices to read/write from. 'dm_rh_get_state' was checking if the return value of 'in_sync' was 1 to determine if the region was DM_RH_CLEAN. Since 'dm_bit' (and by extension 'log_test_bit' and 'in_sync') was returning powers of 2, DM_RH_CLEAN was rarely being reported as it should have been. Thinking the region was out-of-sync, the mirroring code would write only to the primary device. When the primary device was failed, all of those writes were lost - leaving the entire mirror corrupted.

Handle failure of all mirrored log devices and all but one mirror leg.
Disallow mirrored logs in cluster mirrors. The cluster log daemon (cmirrord) is not multi-threaded and can handle only one request at a time. When a log is stacked on top of a mirror (which itself contains a 'core' log), it creates a situation that cannot be solved without threading. When the top level mirror issues a "resume", the log daemon attempts to read from the log device to retrieve the log state. However, the log is a mirror which, before issuing the read, attempts to determine the 'sync' status of the region of the mirror which is to be read. This sync status request cannot be completed by the daemon because it is blocked on a read I/O to the very mirror requesting the sync status.

Clarify help text for vg_mda_count.
It's not enough to check for the kernel module in the case of cluster mirrors, we must also check that the log daemon (cmirrord) is running. The log module can be auto-loaded, but the daemon cannot be "auto-started". Failing to check for the daemon produces cryptic messages that customers have a hard time deciphering. (The system messages do report that the log daemon is not running, but people don't seem to find this message easily.) Here are examples of what is printed when the module is available, but the log daemon has not been started. [root@bp-01 LVM2]# lvcreate -m1 -l1 -n lv vg Shared cluster mirrors are not available. [root@bp-01 LVM2]# lvcreate -m1 -l1 -n lv vg -v Setting logging type to disk Finding volume group "vg" Archiving volume group "vg" metadata (seqno 3).

Correct LV list order used by lvconvert when splitting a mirror.
Fix for bug 614164: No check for existing name when splitting mirror The user could use the same name as an existing LV when specifying a name for an LV split off from a mirror. This causes all sorts of issues.
2010-07-14 02:24:39 +04:00
Check if LV with specified name already exists when splitting a mirror.
Fix for bugs: 612248 & 612291 Split mirror issues The main problem with these bugs was that the newly split off LV was not being suspended properly. This meant that the memlock count was not being balanced, the DM devices were not being renamed, and some DM devices which should have been removed were not. I've also renamed some of the variables and added comments to make things clearer as to what is going on. (I can break this patch in two if it means easier review.)

Add prompt if using --metadataignore argument with vgmetadatacopies. When using vgmetadatacopies value other than "umanaged" (0), prompt the user if the usage of --metadataignore would change the value of vgmetadatacopies. The main 2 cases are: 1) pvchange --metadataignore 2) vgextend --metadataignore We leave the prompt check in the tools, and do not change anything if the user says 'n'. Examples: vgextend --metadataignore y vgtest /dev/loop0 Setting metadataignore will override preferred number of copies of VG vgtest metadata. Are you sure? [y/n]: y No physical volume label read from /dev/loop0 Physical volume "/dev/loop0" successfully created Volume group "vgtest" successfully extended pvchange --metadataignore y /dev/loop3 Setting metadataignore on /dev/loop3 will override preferred number of copies of VG vgtest metadata. Are you sure? [y/n]: y WARNING: Changing preferred number of copies of VG vgtest metadata from 3 to 2 Physical volume "/dev/loop3" changed 1 physical volume changed / 0 physical volumes not changed Signed-off-by: Dave Wysochanski <dwysocha@redhat.com>

Prompt if metadataignore with vgextend or pvchange would adjust vg_mda_copies.
Adjust vg_mda_copies if metadataignore given with vgextend or pvchange.
Adjust auto-metadata repair and caching logic to try to cope with empty mdas. - If a PV contained empty mdas, the auto-recovery code was not kicking in. - The 'inconsistent' state was getting lost when metadata was cached so recovery didn't kick in. But leave the behaviour alone when using precommitted metadata because of a warning in a confusing FIXME. In my testing, pvs and vgs didn't repair inconsistent metadata like they used to do. (How many other tools fail similarly now?) And there should be no need to cache inconsistent metadata because it is supposed to get repaired under the protection of a write lock immediately it is discovered. This code is in need of a redesign based on first principles. I still see bugs in this code and this commit is risky.

Fix for bz608048 from Taka... The same region size is used for both mirror volume and mirrored log volume, but when the physical extent size is bigger than region size, the size of mirror leg for mirrored log is smaller than the region size and lvcreate command fails. This patch adjusts a region size of mirrored log to a smaller value of region size or physical extent size. [This patch ensures that the region_size of the mirrored log does not exceed the size of the mirrored log itself, which would violate the kernel constraint: (region_size <= ti->len).] Signed-off-by: Takahiro Yasui <takahiro.yasui@hds.com> Signed-off-by: Jonathan Brassow <jbrassow@redhat.com>

Clean up cluster lock mode and flags definition. Code is mixing up internal DLM and LVM definitions of lock modes and flags. OpenAIS and singlenode locking do not depend on DLM but code currently cannot be compiled without libdlm.h! LCK_* flags is LVM abstraction, used through all the code. Only low-level backend (clvmd-cman etc) should use DLM definitions, also this code should do all needed conversions. Because there are two DLM flags used in generic code (NOQUEUE, CONVERT) we define it similar way like lock modes. (So all needed binary-compatible flags are on one place in locking.h) (Further code cleaning still needed, though:-)

Skip internal lvm devices in scan if ignore_suspended_devices is set.
Currently if clvmd is running and user issues vgscan, the device cache file is dumped both in vgscan and clvmd process. Unfortunately, clvmd calls lvmcache_label_scan, it properly destroys persistent filter, but during persistent_filter_dump it merges old cache content back! This causes that change in filters is not properly propagated into device cache after vgscan on cluster. (Only new devices are added.) https://bugzilla.redhat.com/show_bug.cgi?id=591861

Fix lvconvert error message when existing mirrored LV is not found.
Set appropriate udev flags for reserved LVs. There's no need for foreign udev rules to touch LVM reserved devices (snapshot, pvmove, _mlog, _mimage, _vorigin) even if they happen to be visible. The same applies for /dev/disk content - no need to create any content for these devices (and so no need to run any "blkid" etc.). This also prevents setting any inotify "watch" from udev rules on such devices that is a source of race conditions (the rules need to honor DM_UDEV_DISABLE_OTHER_RULES_FLAG for this to work though).

Rename lvm_dump.sh to lvmdump.sh.
What's new.
2010-04-14 17:52:20 +04:00
Allow incomplete mirror restore in lvconvert --repair upon insufficient space.
Do not reset position in metadata ring buffer on vgrename and vgcfgrestore. We should write metadata into next position in the ring buffer while calling vgrename and vgcfgrestore. At this code level (_vg_write_raw), we were not able to determine if this is a rename or not. If yes, then accompanying VG structure passed here has a new name set, not the old one. When looking for a location where to put metadata next, we were given a NULL value because of failed VG name comparison (in _find_vg_rlocn) between the name in existing metadata and metadata we're just about to write. This resets the position in the ring buffer, overwriting any existing metadata (and also incorrectly updates the cache to "orphan" afterwards). This patch just adds old_name item in struct volume_group that we can check and use if necessary and detect renames at lower layers as well. The same applies for vgcfgrestore, but here we're using a special value of old_name, an empty string, to disable the check with existing metadata totally.
2010-04-14 17:09:16 +04:00
Do not reset position in metadata ring buffer on vgrename and vgcfgrestore.
Allow VGs with active LVs to be renamed.
2010-04-14 17:03:06 +04:00
Allow VGs with active LVs to be renamed.
Use UUIDs instead of names while processing event handlers. Internally, we used DM names instead of UUIDs while processing event handlers. This caused problems while trying to vgrename a VG with active LVs where the names are being changed and so the devices were not found then. The patch also contains a little bit of refactoring, moving "build_dlid" code found in dev_manager.c to "build_dm_uuid", now in lvm-string.c (so we have build_dm_uuid and build_dm_name at one place).
2010-04-14 17:01:38 +04:00

Install .a and .so links into $(usrlibdir).
Add --enable-write_install options to install user-writable files.
INSTALL rules updates Patch is inspired by Debian's extra patch. - removes OWNER & GROUP make vars they are parts of INSTALL command. - adds INSTALL_PROGRAM for executable, uses $(INSTALL) - adds INSTALL_DATA for non-executable data, uses ($INSTALL) - adds INSTALL_WDATA for writable non-executable data, uses ($INSTALL) - adds configure option --enable-write_install - to support installatin of writable files used by distribution - replaces usage of ifeq @LIB_SUFFIX@ with $(LIB_SUFFIX) - installs .a files from static builds without executable flag - installs .a files to $(usrlibdir) instead of $(libdir) - installs all static binaries to $(staticdir) - create .so links for devel package in $(usrlibdir) instead of $(libdir) - makes .so and .so.LIB_VERSION files within builddir - removes VERSIONED_SHLIB and created versioned LIB_SHARED automagicaly - install LIB_SHARED via install_lib_shared target - install plugins via install_lib_shared_plugin target - prints whole 'install' command during installation instead of less informative "Installing $(something) $(somewhere)" - install multiple man pages with one INSTALL command - use DISTCLEAN_TARGETS instead of creating multiple distclean targets
2010-04-10 01:42:48 +04:00
Use INSTALL_PROGRAM/DATA/WDATA target.
Use vpath instead of VPATH. Usage of VPATH makes troubles when used within $(builddir). Not only source files are being found through VPATH, but targets as well. (make --debug=v) Thus if user builds the code in $(srcdir) and also in some $(builddir) he gets mangled results as some generated files (i.e. .export.sym) are 'reused' from $(srcdir) instead of $(builddir). This patch switches to use vpath were we could explicitly name suffixes that should be looked via vpath - we must take care, we do not generate files with these suffixes: .c, .in, .po, .exported_symbols
2010-04-10 01:34:25 +04:00
Switch from using VPATH to vpath in Makefiles.

Always use blocking lock for VGs and orphan locks. Because we have now strong rule for lock ordering: - VG locks must be taken in alphabetical order - ORPHAN locks must be the last vgs_locked() is now not needed. This fixes problem with orphan locking, e.g. vgremove VG1 | vgremove VG2 lock(VG1) | lock(VG2) lock(ORPHAN) | lock(ORPHAN) -> fail, non-blocking https://bugzilla.redhat.com/show_bug.cgi?id=578413 (More similar places in code.)

Allocate all memory for segments from private VG mempool.
Do not traverse PV segment list twice. In addition to previous patch, we really do not need to search for segment which was just allocated in split request. Make pv_split_segment function return newly allocated (split) segment also. (So after this patch, there is only one user of slow find_peg_by_pe).

Optimise searching PV segments for seeking the most recently-added.
Remove vg_validate call when parsing cached metadata. vg_validate call is an adept to optimisation, it is very ineeficient and slow. Anyway, we should call it only before writing data to disk. The call in lvmcache was just temporary validation, we realy do not need to revalidate cached metadata every time. (Actually, I added that there just to prove that cache works properly and forgot to remove it.) Patch removes it from lvmcache completely, this can hit only internal bug in export function (and this bug must be detected in any vg_write call anyway before).
2010-03-31 21:20:44 +04:00
Remove vg_validate call when parsing cached metadata.
Use hash table for quick lv reference when reading metadata. The _read_vg uses already hash for PVs to optimise reading of large VGs and avoiding repeated PV list traversing. Use the same aproach to speed up parsing VG with many LVs.

Do not allow {vg|lv}change --ignoremonitoring if on clustered VG. clvmd does not propagate DMEVENTD_MONITOR_IGNORE. Update get_activation_monitoring_mode() to check if the VG that the LV is being activated in is clustered. If so, skip it. Any get_activation_monitoring_mode() error will cause the associated LV (or VG) to be skipped during activation. Both vgchange_single() and lvchange_single(), which call get_activation_monitoring_mode(), are called by their respective process_each_..() method.

Add ability to create mirrored logs for mirror LVs.
Fix clvmd cluster propagation of dmeventd monitoring mode. clvmd's do_lock_lv() already properly controls dmeventd monitoring based on LCK_DMEVENTD_MONITOR_MODE in lock_flags -- though one small fix was needed for this to work: _lock_for_cluster() must treat dmeventd_monitor_mode()'s return as a tri-state value. Also cleanup do_lock_lv() to: - explicitly init_dmeventd_monitor() based on LCK_DMEVENTD_MONITOR_MODE - no longer reset init_dmeventd_monitor() to default at the end of do_lock_lv() -- it is unnecessary

Unable to add physical volume '/dev/xxx' to volume group 'xxx'. Internal error: Attempt to unlock unlocked VG xxx. (the same with existing VG and non-existing PV & vgextend) # vgextend vg_test /dev/xxx ... It is caused because code tries to "refresh" cache if md filter is switched on using cache destroy. But we can change filters and rescan even without this machinery now, just use refresh_filters (and reset md filter afterwards). (Patch also discovers cache alias bug in vgsplit test, fix it by using better filter line.)

Add dm_pool_strdup to allocate and copy memory in tag library function.
Refactor vgcreate, vgchange, and lvchange for tag library function.
Refactor snapshot-merge deptree and device removal to support info-by-uuid Add a merging snapshot to the deptree, using the "error" target, rather than avoid adding it entirely. This allows proper cleanup of the -cow device without having to rename the -cow to use the origin's name as a prefix. Move the preloading of the origin LV, after a merge, from lv_remove_single() to vg_remove_snapshot(). Having vg_remove_snapshot() preload the origin allows the -cow device to be released so that it can be removed via deactivate_lv(). lv_remove_single()'s deactivate_lv() reliably removes the -cow device because the associated snapshot LV, that is to be removed when a snapshot-merge completes, is always added to the deptree (and kernel -- via "error" target). Now when the snapshot LV is removed both the -cow and -real devices get removed using uuid rather than device name. This paves the way for us to switch over to info-by-uuid queries.

Never scan suspended devices in clvmd. For mirror repair (and similar tasks) it can happen that full device rescan is issued from clvmd. Because code can be in the middle of repair (calling suspend) clvmd should never try to scan suspended devices (otherwise it causes deadlock). Also code must not change ignore_suspended_device flag when doing refresh_filters (called from lvmcache scan code).

Rename mirror_device_fault_policy to mirror_image_fault policy
2010-01-06 16:27:06 +03:00
Rename mirror_device_fault_policy to mirror_image_fault policy.
Remove empty "repaired" devices if empty in lvconvert. The logic was that lvconvert repair volumes, marking PV as MISSING and following vgreduce --removemissing removes these missing devices. Previously dmeventd mirror DSO removed all LV and PV from VG by simply relying on vgreduce --removemissing --force. Now, there are two subsequent calls: lvconvert --repair --use-policies vgreduce --removemissing So the VG is locked twice, opening space for all races between other running lvm processes. If the PV reappears with old metadata on it (so the winner performs autorepair, if locking VG for update) the situation is even worse. Patch simply adds removemissing PV functionality into lvconcert BUT ONLY if running with --repair and --use-policies and removing only these empty missing PVs which are involved in repair. (This combination is expected to run only from dmeventd.)
2010-01-06 16:26:21 +03:00
Remove empty PV devices if lvconvert --repair is using defined policies.
Use fixed buffer to prevent stack overflow in persistent filter dump.

Add --poll flag to vgchange and lvchange to control background daemon launch.
Propagate metadata commit and revert notifications to other cluster nodes.
Proper mask lock mode for vg lock. Lock mode is int masked by LCK_TYPE_MASK, always. Patch also remove uneccessary masking lock flag on sender side, if masking is needed, it is don on client side already.

Properly decode all flags in clvmd messages including VG locks.
Properly handle precommitted cache flag when only committed metadata present.
Resume volumes in reverse order to preserve memlock pairing. If renaming snapshot with virtual origin, the origin is renamed too. But the code must resume LVs in reverse order to properly pair memlock (in cluster locking). (The resume of snapshot resumes origin too and later resume is ignored otherwise.)

Add missing items to WHATS_NEW files. Continue to use 'field' to describe reporting elements.
2010-01-12 00:28:04 +03:00
Fix some pvresize and toollib error paths with missing VG releases/unlocks.
Call explicitly suspend for temporary mirror layer. The memlock_inc() fix is wrong, memlock count is not propagated to long living process (clvmd) and just it underflow there. Also suspend is needed to pre-load precommited metadata on other nodes (remapping to error taget in this case). With explicit suspend we generate lock request and code can update memlock count. (Infinitely "locked" memory caused that fs_unlock() was not called properly and on cluster nodes remains old links in /dev/mapper for not active devices.) (N.B. failing of suspend call here is not handled as fatal error - the LV is going to be removed later anyway.)
2009-12-09 22:53:39 +03:00
Explicitly call suspend for temporary mirror layer.

Always bypass calls to remote cluster nodes for non-clustered VGs.
Permit implicit cluster lock conversion in pre/post callbacks on local node.
Permit implicit cluster lock conversion to the lock mode already held.
Fix lock flag masking in clvmd so intended code paths get invoked.
Get rid of magic masks in cluster locking code - clvmd part. - do_command and lock_vg expect flags (no change here) Bug fixes: - lock_vg should check for NONBLOCK on lock_cmd, flags have this bit masked-out - do_pre/post_command expect do not mask flag at all, this causes that the code inside is never run! (see following patches, these functions expect plain command without flags)
2009-12-09 21:42:02 +03:00
Replace magic masks in cluster locking code by defined masks.
Add missing items to WHATS_NEW files. Continue to use 'field' to describe reporting elements.

Move is_long_lived persistent_filter_dump to happen after every full scan.
Refresh device filters before full device rescan in lvmcache. The sysfs filter initialise hash of available devices using scan of /sys/block. We need to refresh even this hash when performing full scan otherwise the newly appeared device could be rejected, because there is no entry in sysfs filter. This easily could happen when attaching new device to cluster node. (Only force refresh of context in clvmd -R works here now). Unfortunately consequences of this are much worse, missing device part on that node is replaced with missing segment (even when no partial arg is selected) and this directly lead to data corruption. See https://bugzilla.redhat.com/show_bug.cgi?id=538515 Simply fix it by refreshing device filters in lvmcache before performing the full device scan.
2009-11-24 19:10:25 +03:00

Return error status if vgchange fails to activate some volume. (on one node a storage connection failed): # vgchange -a y vg_bar ; echo $? Error locking on node bar-02: Refusing activation of partial LV lv1. Use --partial to override. 1 logical volume(s) in volume group "vg_bar" now active 0 So activation fails on one node, error is correctly printed but status code is wrong. This patch fixes the top level (vgchange) to return proper code (and print # of activated LVs). (lvchange returns error properly here.)

Going forward, we would like to allow users to specify the total number of metadatacopies in a VG rather than on a per-PV basis. In order to facilitate that, introduce --pvmetadatacopes to replace --metadatacopies everywhere. We still allow --metadatacopies for pv commands, but require --pvmetadatacopies for vg commands. Eventually we will introduce --vgmetadatacopies. Once we do that, we should either deprecate --metadatacopies or make it a synonym based on the command (pvmetadatacopies for pv commands, and vgmetadatacopies for vg commands). The latter option would likely just require a simple 'strncpy' check against cmd->command->name to qualify the merge_synonym call. Update nightly tests to cover the pvmetadatacopies synonym. Note that this patch is the result of an eariler review comment for the implicit pvcreate patches. Should apply cleanly on top of the implicit pvcreate patches (I applied after patch 10/10 in that series). NOTE: This patch will require --pvmetadatacopies for vgconvert as --metadatacopies is no longer accepted.
2009-10-06 00:55:56 +04:00
Add --pvmetadatacopies for pvcreate, vgcreate, vgextend, vgconvert.
Add implicit tests for implicit pvcreate during vgcreate and vgextend. Update tests and WHATS_NEW for implicit pvcreate support.

Stop clvmd from automatically doing lock conversions. Now, if a lock is granted at one mode and an attempt to convert it wthout the LCK_CONVERT flag set then it will return errno=EBUSY. This fixes a pretty bad bug in which an LV could be activated exclusively on one node and lvchange -ay on another would convert it to shared! It might break some things in other areas, but I doubt it.

Version 2.02.52 - 15th September 2009
=====================================
Fix process_each_vg / _process_one_vg when vg_read() returns FAILED_LOCKING. Remove the checks for vg_read_error() in most of the tools callback functions and instead make the check in _process_one_vg() more general. In all but vgcfgbackup, we do not want to proceed if we get any error from vg_read(). In vgcfgbackup's case, we may proceed if the backup is to proceed with inconsistent VGs. This is a special case though, and we mark it with the READ_ALLOW_INCONSISTENT flag passed to process_each_vg (and subsequently to _process_one_vg). NOTE: More cleanup is needed in the vg_read_error() path cases. This patch is a start.
2009-09-15 05:38:59 +04:00
Update _process_one_vg to cleanup properly after vg_read_error.

Add devices/data_alignment_detection to lvm.conf. Adds 'data_alignment_detection' config option to the devices section of lvm.conf. If your kernel provides topology information in sysfs (linux >= 2.6.31) for the Physical Volume, the start of data area will be aligned on a multiple of the ’minimum_io_size’ or ’optimal_io_size’ exposed in sysfs. minimum_io_size is used if optimal_io_size is undefined (0). If both md_chunk_alignment and data_alignment_detection are enabled the result of data_alignment_detection is used. Signed-off-by: Mike Snitzer <snitzer@redhat.com>

Revert previous patch that moved VG_ORPHAN lock inside vg_extend. We must hold the VG_ORPHAN lock until we commit to disk. Otherwise, we risk a race condition on vgcreate / vgextend. Reverts the following commit: commit 72a41480ba66d7dc2d05ef8583080b6b08208507 Author: Dave Wysochanski <dwysocha@redhat.com> Date: Fri Jul 10 20:09:21 2009 +0000 Move orphan lock obtain/release inside vg_extend(). With this change we now have vgcreate/vgextend liblvm functions. Note that this changes the lock order of the following functions as the orphan lock is now obtained first. With our policy of non-blocking second locks, this should not be a problem. Signed-off-by: Dave Wysochanski <dwysocha@redhat.com>

Remove extraneous messages for extent_size and alloc_policy upon vgcreate. When converting to the new liblvm functions, the vgcreate code path changed to create a new vg, then set values. As a result of this change, and the fact that we give a user a message if they try to set the same value of a VG attribute (extent_size, alloc_policy, etc), you'll see these 2 extraneous "is already" messages with vgcreate: tools/lvm vgcreate vg2 /dev/loop2 Physical extent size of VG vg2 is already 4.00 MB Volume group allocation policy is already normal Volume group "vg2" successfully created Signed-off-by: Dave Wysochanski <dwysocha@redhat.com> Author: Dave Wysochanski <dwysocha@redhat.com>

Make text metadata read errors for segment areas more precise.
Fix text segment metadata read errors to mention correct segment name.

Fix confusing metadata syntax error messages. If there is syntax error in metadata, it now prints messages like: Couldn't read 'start_extent' for segment 'extent_count'. Couldn't read all logical volumes for volume group vg_test. The segment specification is wrong and confusing. Patch fixes it by introducing "parent" member in config_node which points to parent section and config_parent_name function, which provides pointer to node section name. Also it adds several LV references where possible.

2009-06-07 02:00:20 +04:00
Round up requested readahead to at least one page and print warning.
Fix double releasing of vg when repairing of vg is requested. Several commands calls process_each_vg() and in provided callback it explicitly recovers VG if inconsistent. (vgchange, vgconvert, vgscan) It means that old VG is released and reread but the function above (process_one_vg) tries to unlock and release old VG. Patch moves the repair logic into _process_one_vg() function. It always tries to read vg (even inconsistent) and then decides what to do according new defined parameter. Also patch unifies inconsistent error messages. The only slight change if for vgremove command, where it now tries to repair VG before it removes if force arg is given. (It works similar way before, just the order of operation changed).
2009-06-06 00:00:52 +04:00
Try to repair vg before actual vgremove when force flag provided.

2009-06-01 19:55:06 +04:00
Fix rename of active snapshot with virtual origin.
Fix convert polling to ignore LV with different UUID. When mirror convert polling is started (mainly as backgound process, in lvchange -a y or in lvconvert itself) it tries to read VG and LV identified by its name. Unfortunatelly, the VG can have already different LV under the same name, and various more or less funny things can happen (note that _finish_lvconvert_mirror suspends the volume for example). (the typical example is our testing script which continuously recreates LVs under the same name in the same VG.) This patch adds optional uuid parameter which helps to properly select the monitoring object. For lvconvert polling it is set to LV UUID and both _get_lvconvert_vg and _get_lvconvert_lv uses it to read proper VG/LV. (In the pvmove case it is NULL, here we poll for physical volume name).
2009-06-01 18:43:27 +04:00
Fix convert polling to ignore LV with different UUID.
Fix readahead calculation problems. During vgreduce is failed mirror image replaced with error segment, this segmant type has always area_count == 0. Current code expects that there is at least one area with device, patch fixes it by additional check (fixes segfault during vgreduce). Also do not calculate readahead in every lv_info call, we only need to cache PV readahead before activation calls which locks memory.
2009-06-01 16:43:31 +04:00
Cache underlying device readahead only before activation calls.
Fix segfault when calculating readahead on missing device in vgreduce.

Implement query_resource_fn for cluster_locking.
Support query_resource_fn in locking modules.
Add infrastructure for queriying for remote locks. Current code, when need to ensure that volume is not active on remote node, it need to try to exclusive activate volume. Patch adds simple clvmd command which queries all nodes for lock for given resource. The lock type is returned in reply in text. (But code currently uses CR and EX modes only.)
2009-05-19 14:38:58 +04:00
Introduce CLVMD_CMD_LOCK_QUERY command for clvmd.
If pvmove fails activating mirror volume, try restore to previous state. pvmove now keep suspended devices if temporary mirror creation fails. We can try to restore previous state if it is first attempt to activate pvmove (code basically run the same code as --abort automatically).
2009-05-19 13:51:02 +04:00
Fix pvmove to revert operation if temporary mirror creation fails.
Use PV UUID in hash for device name when exporting metadata. Currently code uses pv_dev_name() for hash when getting internal "pvX" name. This produce corrupted metadata if PVs are missing, pv->dev is NULL and all these missing devices returns one name (using "unknown device" for all missing devices as hash key).
2009-05-19 13:48:32 +04:00
Fix metadata export for VG with missing PVs.

Check max_lv on only place and force the check only for new volume. We can temporarily violate max_lv during mirror conversion etc. (If the operation fails, orphan mirror images are visible to administrator for manual remove for example. Not that this should ever happen:-) Force limit only for lvcreate (and vg merge) command. Patch also adds simple max_lv tests into testsuite
2009-05-14 01:29:10 +04:00
Force max_lv restriction only for newly created LV.

2009-05-14 01:25:45 +04:00
Fix lv_is_visible to handle virtual origin.
Introduce link_lv_to_vg and unlink_lv_from_vg functions. link_lv_to_vg and unlink_lv_from_vg are the only functions for adding/removing logical volume from volume group. Only these function should manipulate with vg->lvs list.
2009-05-14 01:25:01 +04:00
Introduce link_lv_to_vg and unlink_lv_from_vg functions.
Remove vg->lv_count and use counter function. This should not cause problems but simplifies code a lot. (the volumes_count is merged and renamed with lvs_visible function by following patch.)
2009-05-14 01:22:57 +04:00
Remove lv_count from VG and use counter function instead.
Fix snapshot segment import to not use duplicate segments & replace. The snapshot segment (snapshotX) is created twice during the text metadata segment processing. This can cause temporary violation of max_lv count. Simplify the code, snapshot segment is properly initialized in init_snapshot_seg function now and do not need to be replaced by vg_add_snapshot call. The vg_add_snapshot() is now usefull only for adding new snapshot and it shares the same initialization function. The snapshot name is always generated, name paramater can be removed from function call.
2009-05-14 01:21:58 +04:00
Fix snapshot segment import to not use duplicate segments & replace.
Do not query nonexistent devices for readahead.

Do not query nonexistent devices for readahead.
Remove NON_BLOCKING lock flag from tools and set a policy to auto-set. As a simplification to the tools and further liblvm, this patch pushes the setting of NON_BLOCKING lock flag inside the lock_vol() call. The policy we set is if any existing VGs are currently locked, we set the NON_BLOCKING flag. Should be no functional change.
2009-05-13 17:02:52 +04:00
Remove NON_BLOCKING lock flag from tools and set a policy to auto-set.

Fix first_seg() call for empty segment list. The seg variable is temporary variable for list iterator, code cannot expect that after iteration it remains NULL (it contains non-NULL pointer here id list is empty). Patch fixes first_seg function so it now correctly returns NULL for empty segment list.
2009-05-12 23:09:21 +04:00

2009-05-09 17:47:03 +04:00
Reject missing PVs from allocation in toollib.
Fix PV datalign when for values starting prior to MDA area. The dataalign value must always be aligned according to MDA area. The currect code checks if calculated value collides with MDA area but not if the value is so small that it is located before MDA starts. Unfortunatelly there can be also MDA in the end of the device. The patch adds simple check to avoid this miscalculation. Patch expects that first MDA always starts on <= pagesize boundary (this is true for all allowed label sector parameters).
2009-05-07 16:11:50 +04:00
Fix PV datalignment for values starting prior to MDA area. (2.02.45)
Add sparse devices: lvcreate -s --virtualoriginsize (hidden zero origin). Add lvs origin_size field. Fix linux configure --enable-debug to exclude -O2. Still a few rough edges, but hopefully usable now: lvcreate -s vg1 -L 100M --virtualoriginsize 1T

Fix vgreduce --removemissing failure exit code.
Fix remote metadata backup for clvmd Run backup of metadata on remote nodes in the same place like local node - when calling backup(). Introduce backup_locally() which calls only local backup if needed. Remote backup is now trigerred by LCK_VG_BACKUP flag combination (special VG lock). This lock type will call check_current_backup() (including backup_locally() call) and updates metadata on all nodes. (Patch fixes non-functional remote backup, current call during VG lock never triggers.)
2009-04-22 13:39:45 +04:00
Fix remote metadata backup for clvmd.
Pre-release cleanups.

Alloc PV internal structure from VG mempool if possible.
2009-04-22 13:31:30 +04:00
Alloc PV internal structure from VG mempool if possible.
Move metadata backup call after vg_commit. The backup() call store metadata from memory. But in cluster backup() call performs remote nodes metadata backup and it reads data from disk. For metadata backup consistency, patch moves all backup() calls after vg_commit. (Moreover, some tools already do that this way.)
2009-04-21 18:31:57 +04:00
Fix metadata backup to run after vg_commit always.
Tidy lv_hash[_lock] use inside clvmd. - Rename unlock_all to destroy_lvhash, this function is called in cluster shutdown unlocks everything and clean up allocated info space. - Tidy lv_hash_lock use . Except adding free(lvi) in lv_has destructror there is no functional change.
2009-04-21 17:11:28 +04:00
Tidy clvmd volume lock cache functions.
Fix pvseg report for orphan PVs and other devices. If user requests report attribute from PVSEG type and PV is orphan (or all devices is set), the report is empty. Try for example (when only orphan PV are present) #pvs #pvs -o +devices # pvs /dev/sdb1 PV VG Fmt Attr PSize PFree /dev/sdb1 lvm2 -- 46.58G 46.58G # pvs -o +devices /dev/sdb1 (no output) The problem is caused by empty pv->segments list. Fix it by providing fake segment here (similar to fake structures in _pvsegs_sub_single() calls.
2009-04-21 16:59:18 +04:00
Fix pvs report for orphan PVs when segment attributes are requested.
Fix pvs -a for segmented output # pvs -a -o devices Volume group name (null) has invalid characters Skipping volume group (null) ... _pvsegs_sub_single creates fake vg, we need to check that pv is real here.
2009-04-21 16:57:31 +04:00
Fix pvs -a output to not read volume groups from non-PV devices.
Add MMC device type to filters.
2009-04-16 14:16:14 +04:00
Add MMC (mmcblk) device type to filters.
Introduce memory pool per volume group. Since now, all code reading volume group is responsible for releasing the memory allocated by calling vg_release(vg). (For simplicity of use, vg_releae can be called for vg == NULL, the same logic like free(NULL)). Also providing simple macro for unlocking & releasing in one step, tools usualy uses this approach. The global memory pool (cmd->mem) should be used only for global physical volume operations. This patch have to be applied with all subsequent patches to complete memory pool per vg logic. Using separate memory pool has quite bit memory saving impact when using large VGs, this is mainly needed when we have to use preallocated and locked memory (and should not overflow from that memory space).
2009-04-10 13:59:18 +04:00
Introduce memory pools per volume group (to reduce memory for large VGs).
Pre-release cleanups.

Enable use of cached metadata for pvs & pvdisplay. Currently PV commands, which performs full device scan, repeatly re-reads PVs and scans for all devices. This behaviour can lead to OOM for large VG. This patch allows using internal metadata cache for pvs & pvdisplay, so the commands scan the PVs only once. (We have to use VG_GLOBAL otherwise cache is invalidated on every VG unlock in process_single PV call.)

Fix lv_count when manipulating with snapshots and max_lv is set. Patch fixes these problems: - during the snapshot creation process, it needs create 2 LVs, one is cow, second becomes snapshot. If the code fails in vg_add_snapshot, code lvcreate will not remove LV cow volume. - if max_lv is set and VG contains snapshot, it can happen that during the activation lv_count is temporarily increased over the limit and VG metadata are not properly processed see https://bugzilla.redhat.com/show_bug.cgi?id=490298 - vgcfgrestore alows restore with max_lv set to lower valuer that actual LV count. This later leads to situation that max_lv is completely ignored. - vgck doesn't call vg_validate(). It should at least try:-) Signed-off-by: Milan Broz <mbroz@redhat.com>

Fix possible increasing in memory allocation if refreshing_context (for example when CLVMD_CMD_LOCK_VG for is called during vgscan). If clvmd calls LV lock, it calls /* clean the pool for another command */ dm_pool_empty(cmd->mem); to clean up memory pool after command. Unfortunately, do_refresh_cache() do not call this and because during it operation it allocates some memory, the pool increases. Also do_refresh_cache should use lvm_lock (it manipulates with lvm internal data). The same applies for lvm_backup command. Signed-off-by: Milan Broz <mbroz@redhat.com>

Add --dataalignment to pvcreate to specify alignment of data area. (mbroz) This patch is not fully tested and leaves some related bugs unfixed. Intended behaviour of the code now: pe_start in the lvm2 format PV label header is set only by pvcreate (or vgconvert -M2) and then preserved in *all* operations thereafter. In some specialist cases, after the PV is added to a VG, the pe_start field in the VG metadata may hold a different value and if so, it overrides the other one for as long as the PV is in such a VG. Currently, the field storing the size of the data area in the PV label header always holds 0. As it only has meaning in the context of a volume group, it is calculated whenever the PV is added to a VG (and can be derived from extent_size and pe_count in the VG metadata).
2009-02-22 22:00:26 +03:00
Add --dataalignment to pvcreate to specify alignment of data area.
Fix interrupt unblocking after vgcreate, for example: drop_cached_metadata() previously left _vg_lock_count incremented. Other locks are always held during drop_cached_metadata() so there's no need to increment+decrement it.

Fix "lvremove -f vgname" when vgname contains snapshots. Prior to this patch, "lvremove -f vgname" would fail if vgname contained one or more snapshot LVs. Now this passes, but has a side-effect. If you issue "lvremove vgname" where vgname contains one or more snaps, you will get an extra "y/n" prompt to remove the same snapshot. Example: $ lvs LV VG Attr LSize Origin Snap% Move Log Copy% Convert lvsnap vgtest swi-a- 16.00M lvtest 0.05 lvtest vgtest owi-a- 64.00M $ lvremove vgtest Do you really want to remove active logical volume "lvsnap"? [y/n]: n Logical volume "lvsnap" not removed Do you really want to remove active logical volume "lvsnap"? [y/n]: n Logical volume "lvsnap" not removed Command failed with status code 5.

Fix tracking of validity of PVs with no mdas in lvmcache.
Fix return values for reporting commands when run with no PVs, LVs, or VGs. The new error checking code caught some commands that were returning '0' as an exit status for success. This is incorrect and resulted in a benign error message displayed (see below). As of today, all commands should return a value defined in lib/commands/errors.h (1-5). This results in an exit code of 0 on success, or > 0 on failure (as stated in the lvm.8 man page). Before change: 1. Make sure no PVs are on the system 2. Run 'pvs' Command failed with status code 0. After change: <no output>

CTRL-C Code will exit with: Do you really want to remove volume group "vg2" containing 2 logical volumes? [y/n]: Volume group "vg2" not removed Command failed with status code 5. Internal error: Volume Group vg2 was not unlocked Device '/dev/loop1' has been left open. After change: Do you really want to remove volume group "vg2" containing 2 logical volumes?

. remove_lock_wait.diff remove the definition of "struct lock_wait", which is not used since the switch away from async version saLck . num_nodes should equal to member_list_entries, i.e. joined_list_entires is 0 when a node leaves the group. Thanks to Xinwei Hu for the patch.
2008-04-29 12:55:20 +04:00
Remove unused struct in clvmd-openais, and use correct node count.
The attached patch is a try to make clvmd work correctly on openais stack. It does 2 things. 1. The cpg_deliver_callback make a compare between target_nodeid and our_nodeid. It turns out openais set target_nodeid to 0 sometimes. for broadcasting ? I change the behavior so that lvm will process_remote also on target_nodeid == 0 2. The joined_list passed to cpg_confchg_callback doesn't include the already exist nodes in the group, which leads to an incomplete node_hash. I simply add all other nodes in member_list to node_hash also. Thanks to Xinwei Hu for this patch.

Fix vgsplit to only move hidden 'snapshotN' LVs when necessary. This bug has been around for a long time as far as I can tell. Without this fix, a vgsplit would unconditionally move the 'hidden/internal' snapshot LVs, and result in corrupted metadata in the following case: vg1: contains lv1, lv1snap, both on pvset1 vg1: contains lv2, on pvset2 "vgsplit vg1 vg2 pvset2" would result in "snapshot0" hidden LV being moved to vg2, and the origin and cow being left in vg1. The tools detect the corruption in vg2, but not in vg1.

Some new features.
2002-11-18 17:04:08 +03:00
========================
The new format of LVM metadata is ready for you to test!
We expect it to be more efficient and more robust than the original format.
It's more compact and supports transactional changes and replication.
Should things go wrong on a system, it's human-readable (and editable).

the configuration file.
To convert an existing volume group called vg1 to the new format using
the default settings, use "vgconvert -M2 vg1". See "man vgconvert".
-M (or --metadatatype in its long form) is a new flag to indicate which
format of metadata the command should use for anything it creates.
Currently, the valid types are "lvm1" and "lvm2" and they can be
abbreviated to "1" and "2" respectively. The default value for this
flag can be changed in the global section in the config file.
Backwards-compatible support for the original LVM1 metadata format is
maintained, but it can be moved into a shared library or removed
completely with configure's --with-lvm1 option.
Under LVM2, the basic unit of metadata is the volume group. Different
volume groups can use different formats of metadata - vg1 could use
the original LVM1 format while vg2 used the new format - but you can't
mix formats within a volume group. So to add a PV to an LVM2-format
volume group you must run "pvcreate -M2" on it, followed by "vgextend".
With LVM2-format metadata, lvextend will let you specify striping
parameters. So an LV could consist of two or more "segments" - the
first segment could have 3 stripes while the second segment has just 2.
LVM2 maintains a backup of the current metadata for each volume group
in /etc/lvm/backup, and puts copies of previous versions in
/etc/lvm/archive. "vgcfgbackup" and "vgcfgrestore" can be used to

create and restore from these files. If you fully understand what

2002-11-18 17:04:08 +03:00
you're doing, metadata can be changed by editing a copy of a current
backup file and using vgcfgrestore to reload it.
Please read the pvcreate man page for more information on the new
format for metadata.
All tools that can change things have a --test flag which can be used
to check the effect of a set of cmdline args without really making the
changes.

the work on the cache.
Several of the tools do not yet contain the logic to handle full
recovery: combinations of pvcreate and vgcfgrestore may sometimes be
needed to restore metadata if a tool gets interrupted or crashes or
finds something unexpected. This applies particularly to tools that
work on more than one volume group at once (e.g. vgsplit).
