Description
Original proposal:
- On Map; rbd lock add <image> - If no success; then - "rbd status <image>": check for Watchers, 3 times each 15 secs - If found, ABORT the mapping. The image is still in use in a host that is healthy - "ceph osd blacklist add <previous lock holder>". Image locked without a watcher - steal the lock in <image> - map the image - On Unmap; - rbd lock remove

krbd now supports the exclusive-lock feature which handles this transparently.
