Abstract
A method for file lock recovery in a distributed computer system. The method includes executing a distributed computer system having a plurality of nodes comprising a cluster, and initiating a network file system server migration from one node of the cluster to a different node of the cluster. A migration count is incremented, wherein the migration count is stored at each of the nodes comprising the cluster. File lock services are paused at each of the nodes comprising the cluster. The network file system server migration is completed at the different node of the cluster. The migration count is then decremented in response to the completion. File lock services are then resumed at each of the nodes comprising cluster.
