Patent ID: 8671079

Claim:
A method for recovery of one or more computing nodes of a cluster having plural computing nodes managed with a meta-fileset and plural filesets, the method comprising: detecting failure of one or more computing nodes; blocking client computing node transactions at the cluster upon detecting failure of one or more computing nodes; designating one of the computing nodes as a recovery leader; retrieving to the recovery leader management information stored at the computing nodes; selecting with the recovery node one of the computing nodes as a file system manager; establishing the meta-fileset at the file system manager; selecting one of the computing nodes as a fileset manager for each of the plural filesets; establishing each of the filesets at its selected computing node; and updating the computing nodes to point to the file system manager and fileset managers; recovering client computing nodes of the cluster to use the filesystem manager and fileset managers; and releasing the blocking of the client computing nodes upon recovering client computing nodes of the cluster to use the filesystem manager and fileset managers.
