WARNING: msgcnt x: mesg 081: V-2-81: possible network partition detected
This message displays when CFS detects a possible network partition and disables the file system locally, that is, on the node where the message appears.
There are one or more private network links for communication between the nodes in a cluster. At least one link must be active to maintain the integrity of the cluster. If all the links go down, after the last network link is broken, the node can no longer communicate with other nodes in the cluster.
Check the network connections. After verifying that the network connections is operating correctly, unmount the disabled file system and mount it again.
