Fixed In Version: ceph-16.2.8-34.el8cp
Doc Type: Bug Fix
Doc Text:
.Mirror snapshots that are in use by rbd-mirror daemon on the secondary cluster are not removed Previously, as a result of an internal race condition, the mirror snapshot that was in use by the rbd-mirror daemon on the secondary cluster would be removed, causing the snapshot-based mirroring process for the affected image to stop, reporting a "split-brain" error. With this fix, the mirror snapshot queue is extended in length and the mirror snapshot cleanup procedure is amended accordingly. Mirror snapshots that are in use by the rbd-mirror daemon on the secondary cluster are no longer removed and the snapshot-based mirroring process does not stop.
