New VDO targets v6.2.3 corrects support for online rename of VDO device.
If needed if can be disable via new lvm.conf setting:
vdo_disabled_features = [ "online_rename" ]
When removing pool LV from a stacked LV setup, it's been possible
to leak _pmspare and such hidden LV then required manual
user removal.
Fix it by moving automatic removal into _lv_reduce().
When adding replacement raid+integrity images (lvconvert --repair
after a raid image is lost), various errors can cause the function
to exit with an error. On this exit path, the function attempts
to revert new images that had been created but not yet used. The
cleanup failed to account for the fact that not all images needed
to be reverted.
Since commit 77fdc17d70 always include
log_len size into needed extents - however now we may need sometimes
more extents then necessary - mainly when multiple PVs are involved
into allocation.
Add logs_still_needed into calculation of sufficient_pes_free()
When a writecache sublv or an integrity metadata sublv
are partial (missing a dev), set the partial flag on
the upper level LV also, as is done for other sublvs.
Fix the two-step writecache detach in commit c32d7fed4f.
In the case of uncache, the cachevol is removed after
detaching the writecache. When the detach is finished
in the second step, the remove must wait until then.
When using cache with a cachevol, the cache_check tool was
not being run on the cache metadata during activation.
cache_check clears the needs_check flag in the cache
metadata, so if the flag was set due to an unclean
shutdown, the activation would fail.
When 'fsadm resize vg/lv' is used without size, it should just
resize filesystem to match device - but since we now check
for unbound variable in bash - the previous usage no longer
works and needs explicit check.
Verify that corruption is corrected for raid levels other
than raid1. For other raid levels, attempt to corrupt the
given file pattern on each underlying device, since we don't
know which device contains the file being corrupted.
This ensures that corruption is actually be introduced
when testing the other raid levels.
Verify that corruption is being corrected by checking
the integritymismatches count is non-zero for the raid LV,
which includes the total from all images (since we don't
know which image will have the corruption.)
Each integrity image in a raid LV reports its own number
of integrity mismatches, e.g.
lvs -o integritymismatches vg/lv_rimage_0
lvs -o integritymismatches vg/lv_rimage_1
In addition to this, allow the total number of integrity
mismatches from all images to be displayed for the raid LV.
lvs -o integritymismatches vg/lv
shows the number of mismatches from both lv_rimage_0 and
lv_rimage_1.
Enhance VDO man page with description of memory usage
and space requirements chapter.
Remove some unneeded blank lines in man page.
Use more precise terminology.
Correct examples since cpool and vpool are protected names.
filters needing io weren't being run because bcache
wasn't set up. Read the first 4k of the device
before doing filtering or reading ondisk structs to
reduce reads.
It's possible for a machine with a non-4k page size
to create a PV with an mda_header at an offset other
than 4k. Fix pvck --dump to work with these other
mda offsets. pvck --repair will write a new first
mda at 4096 but lvm with other page sizes will work
with this.
The args for pvcreate/pvremove (and vgcreate/vgextend
when applicable) were not efficiently opened, scanned,
and filtered. This change reorganizes the opening
and filtering in the following steps:
- label scan and filter all devs
. open ro
. standard label scan at the start of command
- label scan and filter dev args
. open ro
. uses full md component check
. typically the first scan and filter of pvcreate devs
- close and reopen dev args
. open rw and excl
- repeat label scan and filter dev args
. using reopened rw excl fd
- wipe and write new headers
. using reopened rw excl fd
Older blockdev tool return failure error code with --help,
and since now the tool abort on command failure, lets
detect missing --getsize64 support directly by running
command and check if it returns something usable.
It's likely very hard to have the system with
such old blockdev tool and newer lvm2 compiled.
