Doc Type: Bug Fix
Doc Text:
Previously, the Ceph cluster would become unresponsive when two nodes of same zone are down in a stretch cluster. If the operator restarts in the middle of a mon failover, then multiple mons may get started on the same node, reducing the mon quorum availability. Thus, two mons could end up on the same node instead of being spread across unique nodes. With this update, the operator can now cancel the mon failover when the mon failover times out. And in the event that an extra mon is started during an operator restart, the extra mon will be removed based on topology to ensure these extra mons are not running on the same node or in the same zone, to maintain optimal topology spread.
