How long does it take to perform a cluster reformation?
Cluster reformations can be extremely fast if all nodes join in the message sending for the reformation (for example, if the cause of the reformation was just a missed heartbeat on a busy network). However, if a node actually has failed, it can take up to minute to time that node out and form the new cluster. The approximate amount of time cluster reformation takes can be seen via “cmquerycl”. By using this command, the cluster reformation time is given next to the disks to be used as the cluster lock.
