It would be _really_ good if LVM2 would fail gracefully when a snapshot
fails, or try to discover whether or not it can take the snapshot before
trying. At the very least a big **WARNING** in the _LVM2_ docs and in
lvcreate would help a lot.

I found LVM1 snapshots so perfect that I never thought about them
anymore; LVM2 on 2.6 was a nasty shock that I'd love to see others saved
from.
