mounting a file system subsequent to a failure in a cluster file system having a plurality of
active nodes. The method comprising first upgrading one active node in the cluster tofunction as a cluster manager node. The cluster manager is in communication with allnodes. The cluster manager is assigned manager responsibilities, in part, comprising firstreceiving an active status request from the node requesting to mount a file system. Thecluster manager first queries the quorum nodes to determine whether each nodeconsiders the cluster manager to still have cluster management responsibilities for thefile system. If a majority of quorum nodes consider the cluster manager to still havecluster management responsibilities for the file system then the cluster managerresponds to the requesting node's active status request. Thereafter, the requestingnode proceeds with mounting the file system.
