There exist failure scenarios where abrupt shutdown and/or interruptions to communication may lead to a split-brain situation where the RBD Mirroring process in both Ceph clusters claim to be the primary. In such a situation the operator must decide which cluster has the most recent data and should be elected primary by using the ``demote`` and ``promote`` (optionally with force parameter) actions. After making this decision the secondary cluster must be resynced to track the promoted master, this is done by running the ``resync-pools`` action on the non-master cluster.
