When we added locking originally, we thought about adding a general
--lock flag for rbd commands on a particular image that would acquire
an exclusive lock on the image before doing anything.
Then you could do 'rbd rm --lock', and it would fail if you'd left the
imaged locked. This is easy to implement, but we haven't gotten around
to it. It's in the tracker though: http://tracker.ceph.com/issues/2586
On a related note, Wido is adding an option to prevent accidental data
loss via resize: https://github.com/ceph/ceph/pull/209
