Jonathan Earl Brassow 27ff8813da Allow snapshots in a cluster as long as they are exclusively ... activated. In order to achieve this, we need to be able to query whether the origin is active exclusively (a condition of being able to add an exclusive snapshot). Once we are able to query the exclusive activation of an LV, we can safely create/activate the snapshot. A change to 'hold_lock' was also made so that a request to aquire a WRITE lock did not replace an EX lock, which is already a form of write lock.		2011-02-04 20:30:17 +00:00
