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..
