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 conectivity with the master is restored, the subordinate will automatically re-join the cluster.
