pvmove uses snapshots internally, so this is just another indication of the general principle that LVM snapshots are dangerous.

pvmove uses mirrors, not snapshots.

It works by setting up temporary mirrors for the kernel to sync the data between the old and new locations.

Oh. You're right, of course. (I've only ever encountered one pvmove failure, anyway -- a deadlock -- and it restarted fine on reboot.)
