When a subordinate metadata server detects the irrecoverable loss of the master metadata server, it might execute an HA failover action script. When a subordinate initializes, but is in a network partition or detects that it is in a partition and the master has already re-formed the group, it does not attempt to execute the failover script but simply prints a log message.
No action is required. View the server and cluster logs. If the network partition is repaired and connectivity with the master is restored, the subordinate will automatically rejoin the cluster.
