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".
With problematic kernels raid devices can be occasionaly left with
'frozen' status - try to 'unfreeze' them with idle message on teardown.
Also replace couple greps with 'built-in' dmsetup --select feature.
Note: dmsetup --select currently reports 'No devices found' on stdout
and return success - looks like a bug to fix.
This is somewhat tricky - for test suite we keep using
'set -e -o pipefail' - the effect here is - we get error report
from any 'failing' command in whole pipeline - thus when something
like this: 'lvs | head -1' is used - and 'head' finishes before
lead 'lvs' is done - it recieves SIGPIPE and exits with error,
and somewhat misleading gets occasionally reported depending
of speed of commands.
For this case we have to avoid using standard pipes and rather
switch to using streamed results with temporary output file.
This is all nicely handled with bash feature '< <()'.

Sleep a bit before checking /sys/block dir so the kernel has a moment to
actually put scsi debug device in it...
Some quite old kernels are in troubles with this plain searching grep
without sleep (namely 2.6.32)
modprobe scsi_debug
<sleep .1>
grep -H scsi_debug /sys/block/*/device/model
modprobe -r scsi_debug
Add three new raid tests with io load and table
reloads during reshape for target 1.13.2.
Add a raid0 to raid10 conversion test.
Also add more signals to trap in lvconvert-raid-reshape-load.sh.
lvmdbusd was started, but the process was not recognized by pgrep.
- configure does not make the script executable - set the flag
explicitly when running make check,
- process name changed to lvmdbusd. The previous python3 value
originated from the use of /usr/bin/env.
Avoiding "$(get first_extent_sector "$d")" in the loop
allows the test to succeed in the cluster. Further cluster
analysis needed to get to the core reason.
The lvm2 test suite aims at small test resource footprints
(few PVs, small PV sizes) to run on tmpfs backed loop device.
OTOH, lvconvert-reshape-raid.sh aims to test the maxima of
supported total stripes of 64. This patch adds a prerequisite
conditional to skip tests using more than 14 stripes.
It requires the target version 1.13.1 to avoid deadlocks.
In some cases the message could be slightly misleading so use
here rather conditional.
TODO:
In future we may possibly further tune the message in case we are
certain the level of redundancy protection has not been reduced.
