This brings up an LVM related question I've had.  Can I do this:

  1) take snapshot of 500GB LV
  2) resize source LV to 1TB
  3) run ext2online
  4a) resize succeeds - remove shapshot
  4b) resize fails horribly - copy shapshot to LV and restart
    4b.1) is there a way to "revert" the source LV to the snapshot?
    	(without allocating snapshot as big as source LV)
