hi users,
must be an easy one - what should be(is allowed to do) filesystem

underlying LV?
many thanks,
Hi,
pvmove is generally transparent to the layers above, so you can
continue using the system as usual while a pvmove is in progress.
While I have never seen pvmove actually fail (My desktop encountered a
power failure mid-operation once, and it just continued as if nothing
had happened after rebooting), with a failing hard disk, I would avoid
any additional IO while the operation is in progress.
ok, thanks
maybe a bit more tricky, would now downsizing a FS be one thing OK to
do(probably also fsck) ? while pvmove is working?
furthermore, would lvreduce be OK to take pvmote out of a LV ?
I have a bit of puzzle type of situation here to deal with - started
pvmove but seems that HDD is rather in a bad condition for after two
days pvmove is barely at 4%.
Should I let it finish - or - abort pvmove and try fsck; fsreduce;
lvreduce..
hmmm..
Use ddrescue. pvmove is not intended for data rescuing from failing disks.
ddrescue is using different strategy to quickly read whatever it can,
quickly skipping over any failing regions, attempting to recover those
on later iterations.
