In the example above, the "unamanaged" is internally represented as 18446744073709551615, but this should be ignored while not comparing field directly with "unmanaged" reserved name with = or !=. Users should not be aware of this internal mapping of the reserved value name to its internal value and hence it doesn't make sense for such reserved value to take place in results of <,<=,> and >=. There's no order defined for reserved values!!! It's a special *reserved* value that is taken out of the usual value range of that type. This is very similar to what we have already fixed with 2f7f6932dcd450ba75fe590aba8c09838d2618dc, but it's the other way round now - we're using reserved value name in selection criteria now (in the patch 2f7f693, we had concrete value and we compared it with the reserved value). So this patch completes patch 2f7f693. This patch also fixes this problem: $ lvs -o+read_ahead vg/lvol6 vg/lvol7 -S 'read_ahead > 32k' LV VG Attr LSize Pool Origin Data% Rahead lvol6 vg Vwi-a-tz-- 1.00g pool lvol5 0.00 auto lvol7 vg Vwi---tz-k 1.00g pool lvol6 256.00k Problem: In the example above, the internal reserved value "auto" is in the range of selection "> 32k" - it shouldn't match as well. Here the "auto" is internally represented as MAX_DBL and of course, numerically, MAX_DBL > 256k. But for users, the reserved value should be uncomparable to any number so the mapping of the reserved value name to its interna value is transparent to users. Again, there's no order defined for reserved values and hence it should never match if using <,<=,>,>= operators. This is actually exactly the same problem as already described in 2f7f6932dcd450ba75fe590aba8c09838d2618dc, but that patch failed for size field types because of incorrect internal representation used. With this patch applied, both problematic scenarios mentioned above are fixed now: $ vgs -o vg_name,vg_mda_copies -S 'vg_mda_copies < unmanaged' (blank) $ lvs -o+read_ahead vg/lvol6 vg/lvol7 -S 'read_ahead > 32k' LV VG Attr LSize Pool Origin Rahead lvol7 vg Vwi---tz-k 1.00g pool lvol6 256.00k

* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
* IMPORTANT NOTE ABOUT ADDING A NEW VALUE FOR REPORTING
* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
*
* When adding a new string value to report, try to keep it
* self-descriptive so when it's printed even without the header,
* we can still deduce what it is actually reporting.
*
* If you need more than one descriptive string to mean the same value,
* please define them as reserved values in values.h.
*
* The first reserved value is the one that is printed in reports (unless
* it's a binary value and we have report/binary_values_as_numeric=1 config
* option used OR --binary command line option is used OR we're using an
* output format which must always print binary values in numeric way,
* like json_std output format.
*
* All the other (2nd and further) listed reserved names are synonyms which
* may be also used in selection (-S|--select).
*
* Also, always use proper *_disp functions to display each type of value
* properly. For example, in case of binary values, you should use
* _binary_disp so that we can always switch between numerical (0/1/-1) and
* string representation while reporting the value.

refactor: rename struct lv_with_info used in reporting code to lv_with_info_and_seg_status The former struct lv_with_info is renamed to lv_with_info_and_seg_status as it can hold more than just "info", there's lv's segment status now in addition: struct lv_with_info_and_seg_status { struct logical_volume *lv; struct lvinfo *info; struct lv_seg_status *seg_status; } Where struct lv_seg_status is: struct lv_seg_status { struct dm_pool *mem; struct lv_segment lv_seg; lv_seg_status_type_t type; void *status; /* struct dm_status_* */ } Where lv_seg points to lv's segment that is being reported or processed in general. New struct lv_seg_status keeps the information about segment status - the status retrieved via DM_DEVICE_STATUS ioctl. This information will be used for reporting dm device target status for the LV segment specified. So this patch introduces third level of LV information that is kept for reuse while reporting fields within one reporting line, causing only one DM_DEVICE_STATUS ioctl call per LV segment line reported (otherwise we'd need to call the DM_DEVICE_STATUS for each segment status field in one LV segment/reporting line which is not efficient). This is following exactly the same principle as already introduced by commit ecb2be5d1642aa0142d216f9e52f64fd3e8c3fc8. So currently we have three levels of information that can be used to report an LV/LV segment: - LV metadata itself (struct logical_volume *lv) - LV's DM_DEVICE_INFO ioctl result (struct lvinfo *info) - LV's segment DM_DEVICE_STATUS ioctl result (this status must be bound to a segment, not the whole LV as the whole LV may be composed of several segments of course) (this is the new struct lv_seg_status *seg_status)

report: add infrastructure to recognize fuzzy reserved names and returning dynamic reserved values With fuzzy names we mean the names for which it's hard or even impossible to enumerate all possible variations of the name - the name needs to be evaluated. An example of fuzzy name is a name which has a base (substring) which matches and it can contain arbitrary variations around this base. We can cover human language better with fuzzy names as people may use several different names (or sentences) to denote the same thing. With dynamic values we mean the values which are not constants and they need to be evaluated in runtime. An example of dynamic value is a value which depends on current system state (e.g. time, current configuration or any other state which may change and it needs runtime evaluation). There's a handler that can be registered with reporting/selection using dm_report_reserved_handler instance. This is a central point in which the computation/evaluation happens when processing reserved values. Currently, there are two actions declared: DM_REPORT_RESERVED_PARSE_FUZZY_NAME (translates fuzzy name into canonical name) DM_REPORT_RESERVED_GET_DYNAMIC_VALUE (gets value for canonical name) The handler is then registered as value in struct dm_report_reserved_value (see explaining comments besided the struct dm_report_reserved_value in libdevmapper.h). Also, this patch provides support for simple caching of values used during report/selection via dm_report_value_cache_{set,get}. This is supposed to be used mainly in the dm_report_reserved_handler instances to save values among calls so all the handler calls work with the same base value used in computation/evaluation and/or possibly to save resources if the evaluation is more time-consuming. The cache is attached to the dm_report handle and so the cache is dropped one dm_report is dropped.

report: select: add support for reserved value recognition in report selection string - add struct dm_report_reserved_value Make dm_report_init_with_selection to accept an argument with an array of reserved values where each element contains a triple: {dm report field type, reserved value, array of strings representing this value} When the selection is parsed, we always check whether a string representation of some reserved value is not hit and if it is, we use the reserved value assigned for this string instead of trying to parse it as a value of certain field type. This makes it possible to define selections like: ... --select lv_major=undefined (or -1 or unknown or undef or whatever string representations are registered for this reserved value in the future) ... --select lv_read_ahead=auto ... --select vg_mda_copies=unmanaged With this, each time the field value of certain type is hit and when we compare it with the selection, we use the proper value for comparison. For now, register these reserved values that are used at the moment (also more descriptive names are used for the values): const uint64_t _reserved_number_undef_64 = UINT64_MAX; const uint64_t _reserved_number_unmanaged_64 = UINT64_MAX - 1; const uint64_t _reserved_size_auto_64 = UINT64_MAX; { {DM_REPORT_FIELD_TYPE_NUMBER, _reserved_number_undef_64, {"-1", "undefined", "undef", "unknown", NULL}}, {DM_REPORT_FIELD_TYPE_NUMBER, _reserved_number_unmanaged_64, {"unmanaged", NULL}}, {DM_REPORT_FIELD_TYPE_SIZE, _reserved_size_auto_64, {"auto", NULL}}, NULL } Same reserved value of different field types do not collide. All arrays are null-terminated. The list of reserved values is automatically displayed within selection help output: Selection operands ------------------ ... Reserved values --------------- -1, undefined, undef, unknown - Reserved value for undefined numeric value. [number] unmanaged - Reserved value for unmanaged number of metadata copies in VG. [number] auto - Reserved value for size that is automatically calculated. [size] Selection operators ------------------- ...

In the example above, the "unamanaged" is internally represented as 18446744073709551615, but this should be ignored while not comparing field directly with "unmanaged" reserved name with = or !=. Users should not be aware of this internal mapping of the reserved value name to its internal value and hence it doesn't make sense for such reserved value to take place in results of <,<=,> and >=. There's no order defined for reserved values!!! It's a special *reserved* value that is taken out of the usual value range of that type. This is very similar to what we have already fixed with 2f7f6932dcd450ba75fe590aba8c09838d2618dc, but it's the other way round now - we're using reserved value name in selection criteria now (in the patch 2f7f693, we had concrete value and we compared it with the reserved value). So this patch completes patch 2f7f693. This patch also fixes this problem: $ lvs -o+read_ahead vg/lvol6 vg/lvol7 -S 'read_ahead > 32k' LV VG Attr LSize Pool Origin Data% Rahead lvol6 vg Vwi-a-tz-- 1.00g pool lvol5 0.00 auto lvol7 vg Vwi---tz-k 1.00g pool lvol6 256.00k Problem: In the example above, the internal reserved value "auto" is in the range of selection "> 32k" - it shouldn't match as well. Here the "auto" is internally represented as MAX_DBL and of course, numerically, MAX_DBL > 256k. But for users, the reserved value should be uncomparable to any number so the mapping of the reserved value name to its interna value is transparent to users. Again, there's no order defined for reserved values and hence it should never match if using <,<=,>,>= operators. This is actually exactly the same problem as already described in 2f7f6932dcd450ba75fe590aba8c09838d2618dc, but that patch failed for size field types because of incorrect internal representation used. With this patch applied, both problematic scenarios mentioned above are fixed now: $ vgs -o vg_name,vg_mda_copies -S 'vg_mda_copies < unmanaged' (blank) $ lvs -o+read_ahead vg/lvol6 vg/lvol7 -S 'read_ahead > 32k' LV VG Attr LSize Pool Origin Rahead lvol7 vg Vwi---tz-k 1.00g pool lvol6 256.00k

Also, this patch provides support for simple caching of values used during report/selection via dm_report_value_cache_{set,get}. This is supposed to be used mainly in the dm_report_reserved_handler instances to save values among calls so all the handler calls work with the same base value used in computation/evaluation and/or possibly to save resources if the evaluation is more time-consuming. The cache is attached to the dm_report handle and so the cache is dropped one dm_report is dropped.

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.

refactor: rename struct lv_with_info used in reporting code to lv_with_info_and_seg_status The former struct lv_with_info is renamed to lv_with_info_and_seg_status as it can hold more than just "info", there's lv's segment status now in addition: struct lv_with_info_and_seg_status { struct logical_volume *lv; struct lvinfo *info; struct lv_seg_status *seg_status; } Where struct lv_seg_status is: struct lv_seg_status { struct dm_pool *mem; struct lv_segment lv_seg; lv_seg_status_type_t type; void *status; /* struct dm_status_* */ } Where lv_seg points to lv's segment that is being reported or processed in general. New struct lv_seg_status keeps the information about segment status - the status retrieved via DM_DEVICE_STATUS ioctl. This information will be used for reporting dm device target status for the LV segment specified. So this patch introduces third level of LV information that is kept for reuse while reporting fields within one reporting line, causing only one DM_DEVICE_STATUS ioctl call per LV segment line reported (otherwise we'd need to call the DM_DEVICE_STATUS for each segment status field in one LV segment/reporting line which is not efficient). This is following exactly the same principle as already introduced by commit ecb2be5d1642aa0142d216f9e52f64fd3e8c3fc8. So currently we have three levels of information that can be used to report an LV/LV segment: - LV metadata itself (struct logical_volume *lv) - LV's DM_DEVICE_INFO ioctl result (struct lvinfo *info) - LV's segment DM_DEVICE_STATUS ioctl result (this status must be bound to a segment, not the whole LV as the whole LV may be composed of several segments of course) (this is the new struct lv_seg_status *seg_status)

This is following exactly the same principle as already introduced by commit ecb2be5d1642aa0142d216f9e52f64fd3e8c3fc8. So currently we have three levels of information that can be used to report an LV/LV segment: - LV metadata itself (struct logical_volume *lv) - LV's DM_DEVICE_INFO ioctl result (struct lvinfo *info) - LV's segment DM_DEVICE_STATUS ioctl result (this status must be bound to a segment, not the whole LV as the whole LV may be composed of several segments of course) (this is the new struct lv_seg_status *seg_status)

In the example above, the "unamanaged" is internally represented as 18446744073709551615, but this should be ignored while not comparing field directly with "unmanaged" reserved name with = or !=. Users should not be aware of this internal mapping of the reserved value name to its internal value and hence it doesn't make sense for such reserved value to take place in results of <,<=,> and >=. There's no order defined for reserved values!!! It's a special *reserved* value that is taken out of the usual value range of that type. This is very similar to what we have already fixed with 2f7f6932dcd450ba75fe590aba8c09838d2618dc, but it's the other way round now - we're using reserved value name in selection criteria now (in the patch 2f7f693, we had concrete value and we compared it with the reserved value).

refactor: rename struct lv_with_info used in reporting code to lv_with_info_and_seg_status The former struct lv_with_info is renamed to lv_with_info_and_seg_status as it can hold more than just "info", there's lv's segment status now in addition: struct lv_with_info_and_seg_status { struct logical_volume *lv; struct lvinfo *info; struct lv_seg_status *seg_status; } Where struct lv_seg_status is: struct lv_seg_status { struct dm_pool *mem; struct lv_segment lv_seg; lv_seg_status_type_t type; void *status; /* struct dm_status_* */ } Where lv_seg points to lv's segment that is being reported or processed in general. New struct lv_seg_status keeps the information about segment status - the status retrieved via DM_DEVICE_STATUS ioctl. This information will be used for reporting dm device target status for the LV segment specified. So this patch introduces third level of LV information that is kept for reuse while reporting fields within one reporting line, causing only one DM_DEVICE_STATUS ioctl call per LV segment line reported (otherwise we'd need to call the DM_DEVICE_STATUS for each segment status field in one LV segment/reporting line which is not efficient). This is following exactly the same principle as already introduced by commit ecb2be5d1642aa0142d216f9e52f64fd3e8c3fc8. So currently we have three levels of information that can be used to report an LV/LV segment: - LV metadata itself (struct logical_volume *lv) - LV's DM_DEVICE_INFO ioctl result (struct lvinfo *info) - LV's segment DM_DEVICE_STATUS ioctl result (this status must be bound to a segment, not the whole LV as the whole LV may be composed of several segments of course) (this is the new struct lv_seg_status *seg_status)

Allow dm-cache cache device to be standard LV If a single, standard LV is specified as the cache, use it directly instead of converting it into a cache-pool object with two separate LVs (for data and metadata). With a single LV as the cache, lvm will use blocks at the beginning for metadata, and the rest for data. Separate dm linear devices are set up to point at the metadata and data areas of the LV. These dm devs are given to the dm-cache target to use. The single LV cache cannot be resized without recreating it. If the --poolmetadata option is used to specify an LV for metadata, then a cache pool will be created (with separate LVs for data and metadata.)

Define new functions and vgs/pvs fields related to mda ignore. Define a new pvs field, pv_mda_used_count, and a new vgs field, vg_mda_used_count to match the existing pv_mda_count and vg_mda_count. These new fields count the number of mdas that have the 'ignored' bit clear (they are in use on the PV / VG). Also define various supporting functions to implement the counting as well as setting the ignored flag and determining if an mda is ignored. These high level functions call into the lower level location independent mda ignore functions defined by earlier patches. Note that counting ignored mdas in a vg requires traversing both lists and checking for the ignored bit on the mda. The count of 'ignored' mdas then is defined by having the bit set, not by which list the mda is on. The list does determine whether LVM actually does read/write to the mda, though we must count the bits in order to return accurate numbers for the various counts. Also, pv_mda_set_ignored must search both vg lists for ignored mda. If the state changes and needs to be committed to disk, the ignored mda will be on the non-ignored list. Note also in pv_mda_set_ignored(), we must properly manage the mda lists. If we change the ignored state of an mda, we must change any mdas on vg->fid->metadata_areas that correspond to this pv. Also, we may need to allocate a copy of the mda, as is done when fid->metadata_areas is populated from _vg_read(), if we are un-ignoring an ignored mda.

The list does determine whether LVM actually does read/write to the mda, though we must count the bits in order to return accurate numbers for the various counts. Also, pv_mda_set_ignored must search both vg lists for ignored mda. If the state changes and needs to be committed to disk, the ignored mda will be on the non-ignored list. Note also in pv_mda_set_ignored(), we must properly manage the mda lists. If we change the ignored state of an mda, we must change any mdas on vg->fid->metadata_areas that correspond to this pv. Also, we may need to allocate a copy of the mda, as is done when fid->metadata_areas is populated from _vg_read(), if we are un-ignoring an ignored mda.

Define new functions and vgs/pvs fields related to mda ignore. Define a new pvs field, pv_mda_used_count, and a new vgs field, vg_mda_used_count to match the existing pv_mda_count and vg_mda_count. These new fields count the number of mdas that have the 'ignored' bit clear (they are in use on the PV / VG). Also define various supporting functions to implement the counting as well as setting the ignored flag and determining if an mda is ignored. These high level functions call into the lower level location independent mda ignore functions defined by earlier patches. Note that counting ignored mdas in a vg requires traversing both lists and checking for the ignored bit on the mda.

Allow dm-integrity to be used for raid images dm-integrity stores checksums of the data written to an LV, and returns an error if data read from the LV does not match the previously saved checksum. When used on raid images, dm-raid will correct the error by reading the block from another image, and the device user sees no error. The integrity metadata (checksums) are stored on an internal LV allocated by lvm for each linear image. The internal LV is allocated on the same PV as the image. Create a raid LV with an integrity layer over each raid image (for raid levels 1,4,5,6,10): lvcreate --type raidN --raidintegrity y [options] Add an integrity layer to images of an existing raid LV: lvconvert --raidintegrity y LV Remove the integrity layer from images of a raid LV: lvconvert --raidintegrity n LV Settings Use --raidintegritymode journal|bitmap (journal is default) to configure the method used by dm-integrity to ensure crash consistency. Initialization When integrity is added to an LV, the kernel needs to initialize the integrity metadata/checksums for all blocks in the LV. The data corruption checking performed by dm-integrity will only operate on areas of the LV that are already initialized. The progress of integrity initialization is reported by the "syncpercent" LV reporting field (and under the Cpy%Sync lvs column.) Example: create a raid1 LV with integrity: $ lvcreate --type raid1 -m1 --raidintegrity y -n rr -L1G foo Creating integrity metadata LV rr_rimage_0_imeta with size 12.00 MiB. Logical volume "rr_rimage_0_imeta" created. Creating integrity metadata LV rr_rimage_1_imeta with size 12.00 MiB. Logical volume "rr_rimage_1_imeta" created. Logical volume "rr" created. $ lvs -a foo LV VG Attr LSize Origin Cpy%Sync rr foo rwi-a-r--- 1.00g 4.93 [rr_rimage_0] foo gwi-aor--- 1.00g [rr_rimage_0_iorig] 41.02 [rr_rimage_0_imeta] foo ewi-ao---- 12.00m [rr_rimage_0_iorig] foo -wi-ao---- 1.00g [rr_rimage_1] foo gwi-aor--- 1.00g [rr_rimage_1_iorig] 39.45 [rr_rimage_1_imeta] foo ewi-ao---- 12.00m [rr_rimage_1_iorig] foo -wi-ao---- 1.00g [rr_rmeta_0] foo ewi-aor--- 4.00m [rr_rmeta_1] foo ewi-aor--- 4.00m

RAID: Add scrubbing support for RAID LVs New options to 'lvchange' allow users to scrub their RAID LVs. Synopsis: lvchange --syncaction {check|repair} vg/raid_lv RAID scrubbing is the process of reading all the data and parity blocks in an array and checking to see whether they are coherent. 'lvchange' can now initaite the two scrubbing operations: "check" and "repair". "check" will go over the array and recored the number of discrepancies but not repair them. "repair" will correct the discrepancies as it finds them. 'lvchange --syncaction repair vg/raid_lv' is not to be confused with 'lvconvert --repair vg/raid_lv'. The former initiates a background synchronization operation on the array, while the latter is designed to repair/replace failed devices in a mirror or RAID logical volume. Additional reporting has been added for 'lvs' to support the new operations. Two new printable fields (which are not printed by default) have been added: "syncaction" and "mismatches". These can be accessed using the '-o' option to 'lvs', like: lvs -o +syncaction,mismatches vg/lv "syncaction" will print the current synchronization operation that the RAID volume is performing. It can be one of the following: - idle: All sync operations complete (doing nothing) - resync: Initializing an array or recovering after a machine failure - recover: Replacing a device in the array - check: Looking for array inconsistencies - repair: Looking for and repairing inconsistencies The "mismatches" field with print the number of descrepancies found during a check or repair operation. The 'Cpy%Sync' field already available to 'lvs' will print the progress of any of the above syncactions, including check and repair. Finally, the lv_attr field has changed to accomadate the scrubbing operations as well. The role of the 'p'artial character in the lv_attr report field as expanded. "Partial" is really an indicator for the health of a logical volume and it makes sense to extend this include other health indicators as well, specifically: 'm'ismatches: Indicates that there are discrepancies in a RAID LV. This character is shown after a scrubbing operation has detected that portions of the RAID are not coherent. 'r'efresh : Indicates that a device in a RAID array has suffered a failure and the kernel regards it as failed - even though LVM can read the device label and considers the device to be ok. The LV should be 'r'efreshed to notify the kernel that the device is now available, or the device should be 'r'eplaced if it is suspected of failing.

RAID: Add writemostly/writebehind support for RAID1 'lvchange' is used to alter a RAID 1 logical volume's write-mostly and write-behind characteristics. The '--writemostly' parameter takes a PV as an argument with an optional trailing character to specify whether to set ('y'), unset ('n'), or toggle ('t') the value. If no trailing character is given, it will set the flag.

RAID: Add scrubbing support for RAID LVs New options to 'lvchange' allow users to scrub their RAID LVs. Synopsis: lvchange --syncaction {check|repair} vg/raid_lv RAID scrubbing is the process of reading all the data and parity blocks in an array and checking to see whether they are coherent. 'lvchange' can now initaite the two scrubbing operations: "check" and "repair". "check" will go over the array and recored the number of discrepancies but not repair them. "repair" will correct the discrepancies as it finds them. 'lvchange --syncaction repair vg/raid_lv' is not to be confused with 'lvconvert --repair vg/raid_lv'. The former initiates a background synchronization operation on the array, while the latter is designed to repair/replace failed devices in a mirror or RAID logical volume. Additional reporting has been added for 'lvs' to support the new operations. Two new printable fields (which are not printed by default) have been added: "syncaction" and "mismatches". These can be accessed using the '-o' option to 'lvs', like: lvs -o +syncaction,mismatches vg/lv "syncaction" will print the current synchronization operation that the RAID volume is performing. It can be one of the following: - idle: All sync operations complete (doing nothing) - resync: Initializing an array or recovering after a machine failure - recover: Replacing a device in the array - check: Looking for array inconsistencies - repair: Looking for and repairing inconsistencies The "mismatches" field with print the number of descrepancies found during a check or repair operation. The 'Cpy%Sync' field already available to 'lvs' will print the progress of any of the above syncactions, including check and repair. Finally, the lv_attr field has changed to accomadate the scrubbing operations as well. The role of the 'p'artial character in the lv_attr report field as expanded. "Partial" is really an indicator for the health of a logical volume and it makes sense to extend this include other health indicators as well, specifically: 'm'ismatches: Indicates that there are discrepancies in a RAID LV. This character is shown after a scrubbing operation has detected that portions of the RAID are not coherent. 'r'efresh : Indicates that a device in a RAID array has suffered a failure and the kernel regards it as failed - even though LVM can read the device label and considers the device to be ok. The LV should be 'r'efreshed to notify the kernel that the device is now available, or the device should be 'r'eplaced if it is suspected of failing.

Allow dm-cache cache device to be standard LV If a single, standard LV is specified as the cache, use it directly instead of converting it into a cache-pool object with two separate LVs (for data and metadata). With a single LV as the cache, lvm will use blocks at the beginning for metadata, and the rest for data. Separate dm linear devices are set up to point at the metadata and data areas of the LV. These dm devs are given to the dm-cache target to use. The single LV cache cannot be resized without recreating it. If the --poolmetadata option is used to specify an LV for metadata, then a cache pool will be created (with separate LVs for data and metadata.)

device usage based on devices file The LVM devices file lists devices that lvm can use. The default file is /etc/lvm/devices/system.devices, and the lvmdevices(8) command is used to add or remove device entries. If the file does not exist, or if lvm.conf includes use_devicesfile=0, then lvm will not use a devices file. When the devices file is in use, the regex filter is not used, and the filter settings in lvm.conf or on the command line are ignored. LVM records devices in the devices file using hardware-specific IDs, such as the WWID, and attempts to use subsystem-specific IDs for virtual device types. These device IDs are also written in the VG metadata. When no hardware or virtual ID is available, lvm falls back using the unstable device name as the device ID. When devnames are used, lvm performs extra scanning to find devices if their devname changes, e.g. after reboot. When proper device IDs are used, an lvm command will not look at devices outside the devices file, but when devnames are used as a fallback, lvm will scan devices outside the devices file to locate PVs on renamed devices. A config setting search_for_devnames can be used to control the scanning for renamed devname entries. Related to the devices file, the new command option --devices <devnames> allows a list of devices to be specified for the command to use, overriding the devices file. The listed devices act as a sort of devices file in terms of limiting which devices lvm will see and use. Devices that are not listed will appear to be missing to the lvm command. Multiple devices files can be kept in /etc/lvm/devices, which allows lvm to be used with different sets of devices, e.g. system devices do not need to be exposed to a specific application, and the application can use lvm on its own set of devices that are not exposed to the system. The option --devicesfile <filename> is used to select the devices file to use with the command. Without the option set, the default system devices file is used. Setting --devicesfile "" causes lvm to not use a devices file. An existing, empty devices file means lvm will see no devices. The new command vgimportdevices adds PVs from a VG to the devices file and updates the VG metadata to include the device IDs. vgimportdevices -a will import all VGs into the system devices file. LVM commands run by dmeventd not use a devices file by default, and will look at all devices on the system. A devices file can be created for dmeventd (/etc/lvm/devices/dmeventd.devices) If this file exists, lvm commands run by dmeventd will use it. Internal implementaion: - device_ids_read - read the devices file . add struct dev_use (du) to cmd->use_devices for each devices file entry - dev_cache_scan - get /dev entries . add struct device (dev) to dev_cache for each device on the system - device_ids_match - match devices file entries to /dev entries . match each du on cmd->use_devices to a dev in dev_cache, using device ID . on match, set du->dev, dev->id, dev->flags MATCHED_USE_ID - label_scan - read lvm headers and metadata from devices . filters are applied, those that do not need data from the device . filter-deviceid skips devs without MATCHED_USE_ID, i.e. skips /dev entries that are not listed in the devices file . read lvm label from dev . filters are applied, those that use data from the device . read lvm metadata from dev . add info/vginfo structs for PVs/VGs (info is "lvmcache") - device_ids_find_renamed_devs - handle devices with unstable devname ID where devname changed . this step only needed when devs do not have proper device IDs, and their dev names change, e.g. after reboot sdb becomes sdc. . detect incorrect match because PVID in the devices file entry does not match the PVID found when the device was read above . undo incorrect match between du and dev above . search system devices for new location of PVID . update devices file with new devnames for PVIDs on renamed devices . label_scan the renamed devs - continue with command processing

Add metadata-based autoactivation property for VG and LV The autoactivation property can be specified in lvcreate or vgcreate for new LVs/VGs, and the property can be changed by lvchange or vgchange for existing LVs/VGs. --setautoactivation y|n enables|disables autoactivation of a VG or LV. Autoactivation is enabled by default, which is consistent with past behavior. The disabled state is stored as a new flag in the VG metadata, and the absence of the flag allows autoactivation. If autoactivation is disabled for the VG, then no LVs in the VG will be autoactivated (the LV autoactivation property will have no effect.) When autoactivation is enabled for the VG, then autoactivation can be controlled on individual LVs. The state of this property can be reported for LVs/VGs using the "-o autoactivation" option in lvs/vgs commands, which will report "enabled", or "" for the disabled state. Previous versions of lvm do not recognize this property. Since autoactivation is enabled by default, the disabled setting will have no effect in older lvm versions. If the VG is modified by older lvm versions, the disabled state will also be dropped from the metadata. The autoactivation property is an alternative to using the lvm.conf auto_activation_volume_list, which is still applied to to VGs/LVs in addition to the new property. If VG or LV autoactivation is disabled either in metadata or in auto_activation_volume_list, it will not be autoactivated. An autoactivation command will silently skip activating an LV when the autoactivation property is disabled. To determine the effective autoactivation behavior for a specific LV, multiple settings would need to be checked: the VG autoactivation property, the LV autoactivation property, the auto_activation_volume_list. The "activation skip" property would also be relevant, since it applies to both normal and auto activation.

Add lv_layout_and_type fn, lv_layout and lv_type reporting fields. The lv_layout and lv_type fields together help with LV identification. We can do basic identification using the lv_attr field which provides very condensed view. In contrast to that, the new lv_layout and lv_type fields provide more detialed information on exact layout and type used for LVs. For top-level LVs which are pure types not combined with any other LV types, the lv_layout value is equal to lv_type value. For non-top-level LVs which may be combined with other types, the lv_layout describes the underlying layout used, while the lv_type describes the use/type/usage of the LV. These two new fields are both string lists so selection (-S/--select) criteria can be defined using the list operators easily: [] for strict matching {} for subset matching. For example, let's consider this: $ lvs -a -o name,vg_name,lv_attr,layout,type LV VG Attr Layout Type [lvol1_pmspare] vg ewi------- linear metadata,pool,spare pool vg twi-a-tz-- pool,thin pool,thin [pool_tdata] vg rwi-aor--- level10,raid data,pool,thin [pool_tdata_rimage_0] vg iwi-aor--- linear image,raid [pool_tdata_rimage_1] vg iwi-aor--- linear image,raid [pool_tdata_rimage_2] vg iwi-aor--- linear image,raid [pool_tdata_rimage_3] vg iwi-aor--- linear image,raid [pool_tdata_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_1] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_2] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_3] vg ewi-aor--- linear metadata,raid [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin [pool_tmeta_rimage_0] vg iwi-aor--- linear image,raid [pool_tmeta_rimage_1] vg iwi-aor--- linear image,raid [pool_tmeta_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tmeta_rmeta_1] vg ewi-aor--- linear metadata,raid thin_snap1 vg Vwi---tz-k thin snapshot,thin thin_snap2 vg Vwi---tz-k thin snapshot,thin thin_vol1 vg Vwi-a-tz-- thin thin thin_vol2 vg Vwi-a-tz-- thin multiple,origin,thin Which is a situation with thin pool, thin volumes and thin snapshots.

For example, let's consider this: $ lvs -a -o name,vg_name,lv_attr,layout,type LV VG Attr Layout Type [lvol1_pmspare] vg ewi------- linear metadata,pool,spare pool vg twi-a-tz-- pool,thin pool,thin [pool_tdata] vg rwi-aor--- level10,raid data,pool,thin [pool_tdata_rimage_0] vg iwi-aor--- linear image,raid [pool_tdata_rimage_1] vg iwi-aor--- linear image,raid [pool_tdata_rimage_2] vg iwi-aor--- linear image,raid [pool_tdata_rimage_3] vg iwi-aor--- linear image,raid [pool_tdata_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_1] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_2] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_3] vg ewi-aor--- linear metadata,raid [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin [pool_tmeta_rimage_0] vg iwi-aor--- linear image,raid [pool_tmeta_rimage_1] vg iwi-aor--- linear image,raid [pool_tmeta_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tmeta_rmeta_1] vg ewi-aor--- linear metadata,raid thin_snap1 vg Vwi---tz-k thin snapshot,thin thin_snap2 vg Vwi---tz-k thin snapshot,thin thin_vol1 vg Vwi-a-tz-- thin thin thin_vol2 vg Vwi-a-tz-- thin multiple,origin,thin Which is a situation with thin pool, thin volumes and thin snapshots. We can see internal 'pool_tdata' volume that makes up thin pool has actually a level10 raid layout and the internal 'pool_tmeta' has level1 raid layout. Also, we can see that 'thin_snap1' and 'thin_snap2' are both thin snapshots while 'thin_vol1' is thin origin (having multiple snapshots). Such reporting scheme provides much better base for selection criteria in addition to providing more detailed information, for example: $ lvs -a -o name,vg_name,lv_attr,layout,type -S 'type=metadata' LV VG Attr Layout Type [lvol1_pmspare] vg ewi------- linear metadata,pool,spare [pool_tdata_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_1] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_2] vg ewi-aor--- linear metadata,raid [pool_tdata_rmeta_3] vg ewi-aor--- linear metadata,raid [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin [pool_tmeta_rmeta_0] vg ewi-aor--- linear metadata,raid [pool_tmeta_rmeta_1] vg ewi-aor--- linear metadata,raid (selected all LVs which are related to metadata of any type) lvs -a -o name,vg_name,lv_attr,layout,type -S 'type={metadata,thin}' LV VG Attr Layout Type [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs which hold metadata related to thin) lvs -a -o name,vg_name,lv_attr,layout,type -S 'type={thin,snapshot}' LV VG Attr Layout Type thin_snap1 vg Vwi---tz-k thin snapshot,thin thin_snap2 vg Vwi---tz-k thin snapshot,thin (selected all LVs which are thin snapshots) lvs -a -o name,vg_name,lv_attr,layout,type -S 'layout=raid' LV VG Attr Layout Type [pool_tdata] vg rwi-aor--- level10,raid data,pool,thin [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs with raid layout, any raid layout) lvs -a -o name,vg_name,lv_attr,layout,type -S 'layout={raid,level1}' LV VG Attr Layout Type [pool_tmeta] vg ewi-aor--- level1,raid metadata,pool,thin (selected all LVs with raid level1 layout exactly) And so on...

Add lv_layout_and_type fn, lv_layout and lv_type reporting fields. The lv_layout and lv_type fields together help with LV identification. We can do basic identification using the lv_attr field which provides very condensed view. In contrast to that, the new lv_layout and lv_type fields provide more detialed information on exact layout and type used for LVs. For top-level LVs which are pure types not combined with any other LV types, the lv_layout value is equal to lv_type value. For non-top-level LVs which may be combined with other types, the lv_layout describes the underlying layout used, while the lv_type describes the use/type/usage of the LV. These two new fields are both string lists so selection (-S/--select) criteria can be defined using the list operators easily: [] for strict matching {} for subset matching.

refactor: rename struct lv_with_info used in reporting code to lv_with_info_and_seg_status The former struct lv_with_info is renamed to lv_with_info_and_seg_status as it can hold more than just "info", there's lv's segment status now in addition: struct lv_with_info_and_seg_status { struct logical_volume *lv; struct lvinfo *info; struct lv_seg_status *seg_status; } Where struct lv_seg_status is: struct lv_seg_status { struct dm_pool *mem; struct lv_segment lv_seg; lv_seg_status_type_t type; void *status; /* struct dm_status_* */ } Where lv_seg points to lv's segment that is being reported or processed in general. New struct lv_seg_status keeps the information about segment status - the status retrieved via DM_DEVICE_STATUS ioctl. This information will be used for reporting dm device target status for the LV segment specified. So this patch introduces third level of LV information that is kept for reuse while reporting fields within one reporting line, causing only one DM_DEVICE_STATUS ioctl call per LV segment line reported (otherwise we'd need to call the DM_DEVICE_STATUS for each segment status field in one LV segment/reporting line which is not efficient). This is following exactly the same principle as already introduced by commit ecb2be5d1642aa0142d216f9e52f64fd3e8c3fc8. So currently we have three levels of information that can be used to report an LV/LV segment: - LV metadata itself (struct logical_volume *lv) - LV's DM_DEVICE_INFO ioctl result (struct lvinfo *info) - LV's segment DM_DEVICE_STATUS ioctl result (this status must be bound to a segment, not the whole LV as the whole LV may be composed of several segments of course) (this is the new struct lv_seg_status *seg_status)

So currently we have three levels of information that can be used to report an LV/LV segment: - LV metadata itself (struct logical_volume *lv) - LV's DM_DEVICE_INFO ioctl result (struct lvinfo *info) - LV's segment DM_DEVICE_STATUS ioctl result (this status must be bound to a segment, not the whole LV as the whole LV may be composed of several segments of course) (this is the new struct lv_seg_status *seg_status)

Add metadata-based autoactivation property for VG and LV The autoactivation property can be specified in lvcreate or vgcreate for new LVs/VGs, and the property can be changed by lvchange or vgchange for existing LVs/VGs. --setautoactivation y|n enables|disables autoactivation of a VG or LV. Autoactivation is enabled by default, which is consistent with past behavior. The disabled state is stored as a new flag in the VG metadata, and the absence of the flag allows autoactivation. If autoactivation is disabled for the VG, then no LVs in the VG will be autoactivated (the LV autoactivation property will have no effect.) When autoactivation is enabled for the VG, then autoactivation can be controlled on individual LVs. The state of this property can be reported for LVs/VGs using the "-o autoactivation" option in lvs/vgs commands, which will report "enabled", or "" for the disabled state. Previous versions of lvm do not recognize this property. Since autoactivation is enabled by default, the disabled setting will have no effect in older lvm versions. If the VG is modified by older lvm versions, the disabled state will also be dropped from the metadata. The autoactivation property is an alternative to using the lvm.conf auto_activation_volume_list, which is still applied to to VGs/LVs in addition to the new property. If VG or LV autoactivation is disabled either in metadata or in auto_activation_volume_list, it will not be autoactivated. An autoactivation command will silently skip activating an LV when the autoactivation property is disabled. To determine the effective autoactivation behavior for a specific LV, multiple settings would need to be checked: the VG autoactivation property, the LV autoactivation property, the auto_activation_volume_list. The "activation skip" property would also be relevant, since it applies to both normal and auto activation.

refactor: rename struct lv_with_info used in reporting code to lv_with_info_and_seg_status The former struct lv_with_info is renamed to lv_with_info_and_seg_status as it can hold more than just "info", there's lv's segment status now in addition: struct lv_with_info_and_seg_status { struct logical_volume *lv; struct lvinfo *info; struct lv_seg_status *seg_status; } Where struct lv_seg_status is: struct lv_seg_status { struct dm_pool *mem; struct lv_segment lv_seg; lv_seg_status_type_t type; void *status; /* struct dm_status_* */ } Where lv_seg points to lv's segment that is being reported or processed in general. New struct lv_seg_status keeps the information about segment status - the status retrieved via DM_DEVICE_STATUS ioctl. This information will be used for reporting dm device target status for the LV segment specified. So this patch introduces third level of LV information that is kept for reuse while reporting fields within one reporting line, causing only one DM_DEVICE_STATUS ioctl call per LV segment line reported (otherwise we'd need to call the DM_DEVICE_STATUS for each segment status field in one LV segment/reporting line which is not efficient). This is following exactly the same principle as already introduced by commit ecb2be5d1642aa0142d216f9e52f64fd3e8c3fc8. So currently we have three levels of information that can be used to report an LV/LV segment: - LV metadata itself (struct logical_volume *lv) - LV's DM_DEVICE_INFO ioctl result (struct lvinfo *info) - LV's segment DM_DEVICE_STATUS ioctl result (this status must be bound to a segment, not the whole LV as the whole LV may be composed of several segments of course) (this is the new struct lv_seg_status *seg_status)

report: add support for time (basic) This patch adds support for time values used in reporting fields. The raw values are always stored as number of seconds since epoch. The support that comes with this patch is the basic one which allows only for recognition of strictly formatted date and time in selection criteria (the format follows a subset of formats defined by ISO 8601): date time timezone date: YYYY-MM-DD (or shortly YYYYMMDD) YYYY-MM (shortly YYYYMM), auto DD=1 YYYY, auto MM=01 and DD=01 time: hh:mm:ss (or shortly hhmmss) hh:mm (or shortly hhmm), auto ss=0 hh (or shortly hh), auto mm=0, auto ss=0 timezone (always with + or - sign): +hh:mm or -hh:mm (or shortly +hhmm or -hhmm) +hh or -hh Or directly the time (number of seconds) since Epoch (1970-01-01 00:00:00 UTC) when the number value is prefixed by "@": @number_of_seconds_since_epoch This patch also adds aliases for comparison operators used together with time values which are more intuitive to use: since (as alias for >=) after (as alias for >) until (as alias for <=) before (as alias for <) For example: $ lvmconfig --type full report/time_format time_format="%Y-%m-%d %T %z %Z [%s]" $ lvs -o name,time vg LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] lvol2 2015-04-26 14:52:20 +0200 CEST [1430052740] lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743] $ lvs vg -o name,time -S 'time since "2015-04-26 15:00" && time until "2015-06-30"' LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743] $ lvs vg -o name,time -S 'time since "2015-04-26 15:00" && time until "2015-06-30 6:00"' LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] $ lvs vg -o name,time -S 'time since @1435519541' LV Time lvol0 2015-06-28 21:25:41 +0200 CEST [1435519541] lvol1 2015-06-30 03:25:43 +0200 CEST [1435627543] lvol3 2015-06-30 14:52:23 +0200 CEST [1435668743] This is basic time recognition support that is directly a part of libdevmapper. Recognition of more free-form expressions will be a part of subsequent patches.

lvm2app: Add signed numerical property values Currently lvm2app properties have the following structure: typedef struct lvm_property_value { uint32_t is_settable:1; uint32_t is_string:1; uint32_t is_integer:1; uint32_t is_valid:1; uint32_t padding:28; union { const char *string; uint64_t integer; } value; } lvm_property_value_t; which assumes that numerical values were in the range of 0 to 2**64-1. However, some of the properties were 'signed', like LV major/minor numbers and some reserved values for properties that represent percentages. Thus when the values were retrieved they were in two's complement notation. So for a -1 major number the API user would get a value of 18446744073709551615. The API user could cast the returned value to an int64_t to handle this, but that requires the API developer to look at the source code and determine when it should be done. This change modifies the return property structure to: typedef struct lvm_property_value { uint32_t is_settable:1; uint32_t is_string:1; uint32_t is_integer:1; uint32_t is_valid:1; uint32_t is_signed:1; uint32_t padding:27; union { const char *string; uint64_t integer; int64_t signed_integer; } value; } lvm_property_value_t; With this addition the API user can interrogate that the value is numerical, (is_integer = 1) and subsequently check if it's signed (is_signed = 1) too. If signed, then the API developer should use the union's signed_integer to avoid casting. This change maintains backwards compatibility as the structure size remains unchanged and integer value remains unchanged. Only the additional bit taken from the pad is utilized.

report: select: add support for reserved value recognition in report selection string - add struct dm_report_reserved_value Make dm_report_init_with_selection to accept an argument with an array of reserved values where each element contains a triple: {dm report field type, reserved value, array of strings representing this value} When the selection is parsed, we always check whether a string representation of some reserved value is not hit and if it is, we use the reserved value assigned for this string instead of trying to parse it as a value of certain field type. This makes it possible to define selections like: ... --select lv_major=undefined (or -1 or unknown or undef or whatever string representations are registered for this reserved value in the future) ... --select lv_read_ahead=auto ... --select vg_mda_copies=unmanaged With this, each time the field value of certain type is hit and when we compare it with the selection, we use the proper value for comparison. For now, register these reserved values that are used at the moment (also more descriptive names are used for the values): const uint64_t _reserved_number_undef_64 = UINT64_MAX; const uint64_t _reserved_number_unmanaged_64 = UINT64_MAX - 1; const uint64_t _reserved_size_auto_64 = UINT64_MAX; { {DM_REPORT_FIELD_TYPE_NUMBER, _reserved_number_undef_64, {"-1", "undefined", "undef", "unknown", NULL}}, {DM_REPORT_FIELD_TYPE_NUMBER, _reserved_number_unmanaged_64, {"unmanaged", NULL}}, {DM_REPORT_FIELD_TYPE_SIZE, _reserved_size_auto_64, {"auto", NULL}}, NULL } Same reserved value of different field types do not collide. All arrays are null-terminated. The list of reserved values is automatically displayed within selection help output: Selection operands ------------------ ... Reserved values --------------- -1, undefined, undef, unknown - Reserved value for undefined numeric value. [number] unmanaged - Reserved value for unmanaged number of metadata copies in VG. [number] auto - Reserved value for size that is automatically calculated. [size] Selection operators ------------------- ...
