Still the place can be better to block only particular reshape
operations which ATM cause kernel problems.
We check if the new number of images is higher - and prevent to take
conversion if the volume is in use (i.e. thin-pool's data LV).

error could be reproduced by calling pvs periodically:
#!/bin/bash
while :
do
pvs
sleep 1
done
use top command to watch RES memory of lvmetad. After a few minutes,
its RES memory will grow for a few KB. Then stop calling pvs, while
its RES will not decrease.
This is because, when lvmetad make reponse for clent request, it
will malloc new chunk for s->vgid_to_metadata, while actually the
new chunk should be added to the reponse dm_config_tree, or it will
make the chunk list of s->vgid_to_metadata keep growing.

With the update with commit b6e6ea2d65
the test file has been updated - however stable branch still has
clvmd & lvmetad so we want to omit runnig unit tests for these runs.
The return value from bcache_invalidate_fd() was not being checked.
So I've introduced a little function, _invalidate_fd() that always
calls bcache_abort_fd() if the write fails.
Since VDO is also pool, the old if() case missed to know about this,
and executed unnecesserily initialization of cache pool variables.
This was usually harmless when using 'smaller' sizes of VDO pools,
but for big VDO pool size, we were reporting senseless messages
about big cache chunk sizes.
Until we resolve reshape for 'stacked' devices, we need to disable it.
So users can no longer reshape i.e. thin-pool data volumes, causing
ATM bad thin-pool problems.
The kernel MD runtime requires region size to be larger than stripe size
on striped raid layouts, thus the dm-raid target's constructor rejects
such request.
This causes e.g. an 'lvcreate --type raid10 -i3 -I4096 -R2048 -n lv vg' to fail.
Avoid failing late in the kernel by enforcing region size to be
larger or equal to stripe size.

ev_unset_last_byte() must be called while the fd is still valid.
After a write error, dev_unset_last_byte() must be called before
closing the dev and resetting the fd.
In the write error path, dev_unset_last_byte() was being called
after label_scan_invalidate() which meant that it would not unset
the last_byte values.
After a write error, dev_unset_last_byte() is now called in
dev_write_bytes() before label_scan_invalidate(), instead of by
the caller of dev_write_bytes().
In the common case of a successful write, the sequence is still:
dev_set_last_byte(); dev_write_bytes(); dev_unset_last_byte();

When resizing 2 volumes like thin-pool and it's metadata and they
would be of a different type - command would be actually expecting
both LVs being of a same segtype - and would throw an error in
case they are different.
This patch fixes is by setting a new segtype from last segment of
2nd. extented device.
Also it fixes the possible 'percentage' extension setup that
might have been used for 'primary' volume - while the 'secondary'
LV always goes with direct size - as we do not support 'percentage'
setup for them
This affects maily usage of thin-pool where the extension of
thin-pool data size may also lead to extension of metadata size.
When running cluster test with clvmd, the actual 'monitoring'
happens in cluster - so the 'already monitored' message
is also logged within clvmd code and the command cannot
see such effect.
clvmd was incapable to report this information back to command
so it cannot be displayed this way.
Add 'lvs -o+seg_monitor' validation which also works in clustered mode.
Instead of checking all LVs in a VG - do just a direct copy of LVs
from the existing list ->segs_using_thin_lv.
TODO: maybe it could be better to expose seg_list to /tools...
