2.1.2.6 Cluster Shutdown

When all the nodes in the cluster leave, the determination of whether or not the shared volumes should be recovered has to be made at the next cluster startup. If all nodes left cleanly, there is no need for recovery. If the last node left cleanly and resynchronization resulting from the non-clean leave of earlier nodes was complete, there is no need for recovery. However, recovery must be performed if the last node did not leave cleanly or if resynchronization from previous leaves was not complete.
