Patent abstract
A cluster of computer system nodes share direct read/write access to storage devices via a storage area network using a cluster filesystem. Access to files on the storage devices is arbitrated by the cluster filesystem using tokens. Upon detection of a change in location of the metadata server, client nodes waiting for a token are interrupted to check on the status of at least one of data and node availability.
