Abstract:
Hierarchical recovery of failed computing nodes to operative computing nodes within a cluster of computing nodes is managed by initiating a recovery leader at an operative node that retrieves management information from the operative nodes and applies the management information to recover filesets of a meta-fileset in a hierarchical filesystem. The use of hierarchical filesets throughout the cluster provides more rapid failover by distributing recovery load across computing nodes and supporting recovery of nodes in parallel.
