But it further needs some lvm2 metadata update to maintain the 'state'
of metadata - so if there is again some 'reboot' and PV with cache
appears back - it will not interfere with the system (aka providing
some historical cached blocks,  so just like mirrored leg needs some
care...)

Hi Zdenek,
yes, this is a valid point: if the cache device reappears and starts providing old blocks, then data corruption can happen.

Thanks.
