Doc Type: Bug Fix
Doc Text:
.Snapshot mirroring no longer halts permanently Previously, if a primary snapshot creation request was forwarded to rbd-mirror daemon when the rbd-mirror daemon was axed for some practical reason before marking the snapshot as complete, the primary snapshot would be permanently incomplete. This is because, upon retrying that primary snapshot creation request, `librbd` would notice that such a snapshot already existed. It would not check whether this "pre-existing" snapshot was complete or not. Due to this, the mirroring of snapshots was permanently halted. With this fix, as part of the next mirror snapshot creation, including being triggered by a scheduler, checks are made to ensure that any incomplete snapshots are deleted accordingly to resume the mirroring.
