Re: Squeeze LVM: pvmove failure left with new LVM named /dev/vg0/pvmove0 - Trying to roll back

pvmove works as follows (more or less):
- allocate the destination.
- configure the destination as a mirror of the source.
- update the new mirror (that's what does the heavy lifting).
- break down the mirroring-connection between the destination and source.
- free the source.

So aborting is very straightforward since the source is basically unaffected
by the "pvmove" except at the very very end.
