Commit 989626926c
introduced 2 new tests
lvconvert-raid-takeover-linear_to_raid4.sh and
lvconvert-raid-takeover-raid4_to_linear.sh
which involve raid reshaping.
Bump the checked dm-raid target version to 1.14.0
which has reshape kernel fixes to avoid test suite
runs to hang.
Bump target version to 1.14.0 which contains fixes
for reshape deadlock/corruption to allow tests to
run once the respective fixes show up in kernels.
Remove now superfluous multi-core checks.

Allow "lvconvert --type linear RaidLV" on a raid4 LV
providing convenient interim steps to convert to linear.
Add respective new test
lvconvert-raid-takeover-raid4_to_linear.sh
and
lvconvert-raid-takeover-linear_to_raid4.sh
for linear to raid4 once on it.
When converting from striped/raid0/raid0_meta
to raid6 with > 2 stripes, allow possible
direct conversion (to raid6_n_6).
In case of 2 stripes, first convert to raid5_n to restripe
to at least 3 data stripes (the raid6 minimum in lvm2) in
a second conversion before finally converting to raid6_n_6.
As before, raid6_n_6 then can be converted
to any other raid6 layout.
Enhance lvconvert-raid-takeover.sh to test the
2 stripes conversions to raid6.

"lvconvert --type linear RaidLV" on striped and raid4/5/6/10
have to provide the convenient interim layouts. Fix involves
a cleanup to the convenience type function.
As a result of testing, add missing sync waits to
lvconvert-raid-reshape-linear_to_raid6-single-type.sh.

Conversion to striped from raid0/raid0_meta is directly possible.
Fix a regression setting superfluous interim raid5_n conversion type
introduced by commit bd7cdd0b09.
Add new test script lvconvert-raid0-striped.sh.

Check allocation of thin-pool works on 2PVs, when one is so full,
that even metadata do not fit there (as they need at least 2M,
while 99% of 63MB fills >62MB)
The md filter can operate in two native modes:
- normal: reads only the start of each device
- full: reads both the start and end of each device
md 1.0 devices place the superblock at the end of the device,
so components of this version will only be identified and
excluded when lvm uses the full md filter.
Previously, the full md filter was only used in commands
that could write to the device. Now, the full md filter
is also applied when there is an md 1.0 device present
on the system. This means the 'pvs' command can avoid
displaying md 1.0 components (at the cost of doubling
the i/o to every device on the system.)
(The md filter can operate in a third mode, using udev,
but this is disabled by default because there have been
problems with reliability of the info returned from udev.)
Add tests for linear <-> striped|raid* conversions.
Add region_size config to reshape tests to avoid test
failures in case of it being defined unexpectedly in lvm.conf.

We have been warning about duplicate devices (and disabling lvmetad)
immediately when the dup was detected (during label_scan). Move the
warnings (and the disabling) to happen later, after label_scan is
finished.
This lets us avoid an unwanted warning message about duplicates
in the special case were md components are eliminated during the
duplicate device resolution.
This minor patch fixes grammar in a few messages which get
printed to users. It also fixes the same grammar mistake in
several comments.

While newer system can detect need for 4K mkfs, on older test machines
running test suite over 4k is reporting problems.
Some more generic solution is needed thought.
This test can't use brd (ramdisk) as backend since for some
weird reason lsblk is not listing these device.
TODO: test could be probably rewritten to avoid using lsblk somehow??
When the backend device supports only 4K blocks (like ramdisk)
we cannot use for testing any smaller blocksize.
So recalc test for 4K extent size.
We may possibly introduce one list extra test that
can be executed on devices with 512b sectors to
check lvm2 support those min extent sizes...
In case "lvconvert -mN RaidLV" was used on a degraded
raid1 LV, success was returned instead of an error.
Provide message to inform about the need to repair first
before changing number of mirrors and exit with error.
Add new lvconvert-m-raid1-degraded.sh test.

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.
Instead of using delayer device user 'zero' device and let mirror
do some real work which takes some time.
In case the test machine is too fast - mirror might need to be made bigger
to meet needed criteria.
Also move all test needed this 'zero' PV trick to the end of test
so $dev2 and $dev4 are covered with 'zero' and can take any amount of
write without consuming any real space.
For reporting commands (pvs,vgs,lvs,pvdisplay,vgdisplay,lvdisplay)
we do not need to repeat the label scan of devices in vg_read if
they all had matching metadata in the initial label scan. The
data read by label scan can just be reused for the vg_read.
This cuts the amount of device i/o in half, from two reads of
each device to one. We have to be careful to avoid repairing
the VG if we've skipped rescanning. (The VG repair code is very
poor, and will be redone soon.)
Test that no (Sub)LV remnants persist if the volume group is
not listed in configuration variable activation/volume_list,
hence not activatable thus causing initialization of rmeta
SubLVs to fail.

Correct testing with format 1 and mq policy.
Add testing of 'smq'
Fix testing with clvmd - where logged message is part of clvmd log
and we can only check command status.
Use 4K chunks since some older kernels are not capable
to create striped volumes with smaller size.
TODO: lvm2 should detect this ahead and avoid kernel
reporting "Invalid chunk".
