Fixed In Version: ceph-16.2.7-119.el8cp
Doc Type: Bug Fix
Doc Text:
Cause: As a result of an internal race condition, the mirror snapshot that is still in-use by rbd-mirror daemon on the secondary cluster could be removed. Consequence: Snapshot-based mirroring process for the affected image would stop, reporting a "split-brain" error. Fix: The mirror snapshot queue was extended in length and the mirror snapshot cleanup procedure was amended accordingly. Result: Mirror snapshots that are still in-use by rbd-mirror daemon on the secondary are not removed. Snapshot-based mirroring process does not stop.
