(This is with LVM 2.02.42, device-mapper 1.02.28, kernel 2.6.27.5.)
I'd just pvmoved an unmounted volume without incident. So, I thought,
let's pvmove a mounted one. I know it used to work but now...
hades:/home# pvmove -v --name polipo /dev/hda5 /dev/hdc

I tried 'pvs', but it hung until I did
# dmsetup resume /dev/mapper/global-polipo
whereupon that came back to life. But now, even if I pvmove it after
unmounting, I see:
hades:/home# pvmove -v --name polipo /dev/hda5 /dev/hdc
Finding volume group "global"
Detected pvmove in progress for /dev/hda5

Abort worked:
hades:/home# pvmove --abort
device-mapper: create ioctl failed: Device or resource busy
Unable to reactivate logical volume "pvmove0"
And then the pvmove, of the now-unmounted volume, worked.
Isn't pvmove supposed to not care if things are mounted or not?
