Abstract
A cluster of computer system nodes share direct read/write access to storage devices via a storage area network using a cluster filesystem. During relocation of a server for a distributed name service and recovery of a cluster, entries related to the distributed name service for filesystems is updated. During relocation, a new server for a filesystem informs all nodes in the cluster of the new server's location. During recovery, a process executing on each node deletes entries related to the distributed name service for any filesystem that does not have a server in the recovering cluster.
