The previous method for forcibly changing a clustered VG
to a local VG involved using -cn and locking_type 0.
Since those options are deprecated, replace it with
the same command used for other forced lock type changes:
vgchange --locktype none --lockopt force.
There are likely more bits of code that can be removed,
e.g. lvm1/pool-specific bits of code that were identified
using FMT flags.
The vgconvert command can likely be reduced further.
The lvm1-specific config settings should probably have
some other fields set for proper deprecation.
Generation of man pages is generating lot of barely readable output.
For normal build quietize this a bit.
For original verbose build start to use 'make V=1'
(just like i.e. linux kernel does)
TODO: apply at more places...
The new blkdeactivate -r|mdraidoption wait causes blkdeactivate to wait
for any resync/recovery/reshape that is currently in progress before
deactivating the device.
If this option is used, blkdeactivate calls mdadm -W|--wait before
mdadm -S|--stop.
There was a typo in blkdeactivate --dmoption/--lvmoption/mpathoption,
it had missing "s" at the end and it was not recognized properly, only
short names for the options (-d/-l/-m).
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.
The following commands now pass the device list through a
--select|-S filter before processing:
suspend resume clear wipe_table remove deps status table
Add the new concise format to dmsetup create, either as a single
command-line parameter or from stdin.
Based on patches submitted by
Enric Balletbo i Serra <enric.balletbo@collabora.com>.
Drop 'DMEVENT' make variable and use BUILD_DMEVENTD like with other daemons.
NOTE: by default we do not build dmeventd - maybe time to change
as lot of build targets basically do need dmeventd...
Switch to use SYSTEMD_LIBS and avoid linking systemd library with
every linked tool when dbus notification are enabled.
(TODO add missing testing for lib presence)
Avoid adding -g more then once for debug builds.
Avoid enabling DEBUG_MEM when we build multithreaded tools.
Link executables with -fPIE -pie and --export-dynamic LDFLAGS
Introduce PROGS_FLAGS to add option to pass flags for external libs.
Link lvm2 internally library only when really used.
Link DAEMON_LIBS with daemons.
Pass VALGRIND_CFLAGS internally
Set shell failure mode on couple places.
Create a new table output format that concisely shows multiple devices
on one line.
dmsetup table --concise [device...]
<dev_name>,<uuid>,<flags>[,<table>]*[;<dev_name>,<uuid>,<flags>[,<table>]*]*
Table lines are separated by commas.
Devices are separated by semi-colons.
Flags is currently 'ro' or 'rw' (and might be extended in a
yet-to-be-defined way in future).
Any comma, semi-colon or backslash within a field is quoted by a
preceding backslash.
The format can later be supplied as input to dmsetup or even to the
booting kernel as an alternative way to set up devices.
Based on patches submitted by
Enric Balletbo i Serra <enric.balletbo@collabora.com>.
Add an independent command definition for "vgchange --locktype",
and split the implementation out of the set of common metadata
changes. It is unlike normal metadata changes, and can only
be run by itself. (Changing the lock type is similar in
principle to changing the VG name or the VG system ID; it
effects the ability of any host to see or access the VG.)
At some point this command lost the ability to forcibly change
the lock type of a shared VG to "none" (making it a local VG).
This can be necessary to repair shared VGs (e.g. recovery steps
that occur in vg_read are disabled for shared VGs because
they are not locked properly, or recovering sanlock locks
when the PV holding them is lost.)
"vgchange --locktype none --lockopt force VG" is used as the
method of forcing the shared VG to become local so that it
can be repaired.
Many will look in 'man lvm.conf' expecting to find a
description of the lvm.conf fields, which are not there.
State at the beginning how to get this (by running
lvmconfig.)
The lvm(8) man page never said what LVM is,
it never defined what the acronym LVM stands for,
it never spelled out other common acronyms VG, PV, LV,
and never described what they are.
This adds a very minimal definition which at least defines
the acronyms and entities, but it could obviously be
expanded on, either here or elsewhere.

narrowed down on addressing the escaping of hyphens
in the dynamic creation of manuals whilst avoiding
them in creating help texts. This lead to a sequence
of slipping through hyphens adrressed by additional
patches in aforementioned commit series.
On the other hand, postprocessing dynamically man-generator
created and statically provided manuals catches all hyphens
in need of escaping.
Changes:
- revert the above commits whilst keeping man-generator
streamlining and the detection of any '\' when generating
help texts in order to avoid escapes to slip in
- Dynamically escape hyphens in manaual pages using sed(1)
in the respective Makefile targets
- remove any manually added escaping on hyphens from any
static manual sources or headers
For each section 8 man page, a .8_gen file is created from one of:
.8_main - Old-style man page - content used directly
.8_des and .8_end - Description and end section of a generated page
.8_pregen - Pre-generated page used if the generator fails
Other man sections are not generated and use the suffix .5_main or .7_main.
Developers should use 'make generate' to regenerate the .8_pregen files.
Require that the path argument to dmfilemapd be an absolute path
and document this in tool output, libdevmapper.h and dmfilemapd.8.
The check is also enforced by dm_stats_start_filemapd() to avoid
forking a new process with an invalid path argument.
Add a warning about maximum supported numbers of stripes
with striped LVs realtive to RAID conversions.

Clean up and correct the details around --extents and --size.
lvcreate/lvresize/lvreduce/lvextend all now display the
extents option in usages.
The Size and Number value variables for --size and --extents
are now displayed without the [+|-] prefix for lvcreate.
For this syntax:
lvconvert --thinpool LV1 --poolmetadata LV2
lvconvert --cachepool LV1 --poolmetadata LV2
Restore the metadata swapping behavior in addition to
the pool creation behavior. When LV1 is already a pool,
the metadata LV will be swapped with LV2.
When LV1 is not a pool, it will be converted to a
pool using the specified LV for metadata.
This syntax is no longer advertised because of the
ambiguous behavior. The primary syntaxes for pool
creation and metadata swapping will be the advertised
methods.
Kernel 4.10 (dm-crypt v1.15.0) and later supports loading device
tables with crypt segment having key in kernel keyring retention
service.
dmsetup hid key section of tables output. With this patch dmsetup
no longer hides key section if it detects kernel key description
instead of hex byte representation of key itself.
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).
Enforce mirror/raid0/1/10/4/5/6 type specific maximum images when
creating LVs or converting them from mirror <-> raid1.
Document those maxima in the lvcreate/lvconvert man pages.

Currently, the output is separated in 3 parts and each part can go into
a separate and user-defined file descriptor:
- common output (stdout by default, customizable by LVM_OUT_FD environment variable)
- error output (stderr by default, customizable by LVM_ERR_FD environment variable)
- report output (stdout by default, customizable by LVM_REPORT_FD environment variable)
For example, each type of output goes to different output file:
[0] fedora/~ # export LVM_REPORT_FD=3
[0] fedora/~ # lvs fedora vg/abc 1>out 2>err 3>report
[0] fedora/~ # cat out
[0] fedora/~ # cat err
Volume group "vg" not found
Cannot process volume group vg
[0] fedora/~ # cat report

Another example in LVM shell where the report goes to "report" file:

Although the use of the first region_id in a group to store the
DMS_GROUP=... aux_data tag is an internal implementation detail,
it has a user visible consequence in that deleting this region will
cause the group to disappear: add an explanation of this to the
'group' command and 'Regions, areas, and groups' section.
The MD raid6 personality being used to drive lvm raid6 LVs does
read-modify-write updates to any stripes and thus relies on correct
P and Q Syndromes being written during initial synchronization or
it may fail reconstructing proper user data in case of SubLVs failing.
We may not allow the '--nosync' option on
creation of raid6 LVs for that reason.
Update/fix 'man lvcreate' in that regard.
add lvcreate-raid-nosync.sh test script.
- Resolves rhbz1358532
'lvchange --resync LV' or 'lvchange --syncaction repair LV' request the
RAID layout specific parity blocks in raid4/5/6 to be recreated or the
mirrored blocks to be copied again from the master leg/copy for raid1/10,
thus not allowing a rebuild of a particular PV.
Introduce repeatable option '--[raid]rebuild PV' to allow to request
rebuilds of specific PVs in a RaidLV which are known to contain corrupt
data (e.g. rebuild a raid1 master leg).
Add test lvchange-rebuild-raid.sh to test/shell doing rebuild
variations on raid1/10 and 5; add aux function check_status_chars
to support the new test.
- Resolves rhbz1064592
with respect to the changed, configurable default behaviour
introduced with commit 7eb7909193.
E.g. raid default of 2 stripes rather than number of PVs in the VG
or on the command line minus one.
The syntax for converting an LV to a thin LV
included an unnecessary --thin option. I was
probably still confused about these options
when writing this.
Synopsis are very useful for quick orientation and also
we provide then for all remaining command.
Also list ALL supported options in a single ordered list,
user should not seek for them.
blkdeactivate -m disablequeueing causes "multipathd disablequeueing maps"
call inside blkdeactivate script before deactivating devices. This
avoids a situation where blkdeactivate may wait for paths to appear if
multipath is set to queueing and there's a stack of other devices and/or
mount points on top of such multipath device.

When logging to epoch files we would like to prevent creating too large
log files otherwise a spining command could fulfill available space
very easily and quickly.
Limit for to 100000 per command.
Make it clear that the "aux data" presented in reports is the user
data stored in the field (and does not include any library-internal
state such as group descriptors) by renaming the field to user_data
and changing the heading to "UserData".
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.
