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.
Add to commits 87117c2b25 and 0b8bf73a63 to avoid refreshing two
times altogether, thus avoiding issues related to clustered, remotely
activated RaidLV. Avoid need to repeat "lvchange --refresh RaidLV"
two times as a workaround to refresh a RaidLV. Fix handles removal
of temporary *-missing-* devices created for any missing segments
in RAID SubLVs during activation.
Because the kernel dm-raid target isn't able to handle transiently
failing devices properly we need
"[dm-devel][PATCH] dm raid: fix transient device failure processing"
as well.
test: add lvchange-raid-transient-failures.sh
and enhance lvconvert-raid.sh

To be able to detect lvm2 command is not leaking some
'unexpected' device - remove all devices before
test exits by its own command so test teardown
now can check what was 'left' unexpectedly.
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
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

Fix missing wait so we have paired waiting.
Also 'wait' for precise PID to get 'exit' code.
Test for 'error' replacing only with newer snapshot targets.
The old one will wait for resume.
Note: 'wait -n' is not always available so can't be used..
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.
Though I'm not quite sure why we push this limit on user,
current --repair logic requires user to wait outside of command.
TODO: I'm not quite sure this repair logic is 'the most wanted'.
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.

Commit 199697accf 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.
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.
