Add simple helper/wrapper check function to check result
of dmsetup call i.e.:
check grep_dmsetup table vg-lv "grep_expected"
check grep_dmsetup status vg-lv -v "grep_unexpected"
Correction for aux test result ([] -> if;then;fi)
Use issue_discard to lower memory demands on discardable test devices
Use large devices directly through prepare_pvs
I'm still observing more then 0.5G of data usage through.
Particullary:
'lvcreate' followed by 'lvconvert' (which doesn't yet support --nosync
option) is quite demanging, and resume returns quite 'late' when
a lot of data has been already written on PV.
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.
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.

- Prevent --lvmshell with --nojson, not a valid combination
- If user is preventing json, then no lvmshell usage
- Return boolean on Manager.UseLvmShell
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).
'pvmove -n name pv1 pv2' called with the name of a top-level LV
failed with mentioned commit.
Enhance pvmove-raid-segtypes.sh to test for prohibited RAID SubLV moves.
RAID6 LVs may not be created with --nosync or data corruption
may occur in case of device failures. The underlying MD raid6
personality used to drive the RaidLV performs read-modify-write
updates on stripes and thus relies on properly written parity
(P and Q Syndromes) during initial synchronization.
Once on it, enhance test to create/extend more and
larger RaidLVs and check sync/nosync status.
Commit 76ef2d15d8 introduced
raid0 <-> raid4 takeover and full mirror <-> raid1 support.
Add tests for these conversions.
Tests exposed a kernel semantics change freezing resynchronization
on conversions from raid0[_meta] -> raid4 or adding raid1 legs
because kernel kept the RAID mapped device in 'frozen' state unless
an 'idle' message was sent or the table was reloaded (kernel patch pending).
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.

'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.
