[ceph-users] Fwd: question on rbd locks

Hello All, Is there a way to specify that a lock (shared or exclusive) on an rbd volume be released if the client machine becomes unreachable or irresponsive? In one of our clusters, we use rbd locks on volumes to make sure provide a kind of shared or exclusive access - to make sure there are no writers when someone is reading and there are no readers when someone is writing. However, we often run into issues when one of the machines gets into kernel panic or something and the whole pipeline gets stalled. So is there a way to tell ceph to release the lock if the client becomes unavailable? Thanks, Shridhar
