ABSTRACT:
Approaches are disclosed for reconfiguring nodes in a cluster file system after new nodes are added to the cluster file system or when node configuration data is changed. According to one aspect of the invention, counters and node configuration data is stored on a volume in a cluster file system. Nodes periodically inspect the counters, and, if it is determined that a node has been added to the cluster file system, or, if the node determines that node configuration data for a node has changed, the node (and other nodes) may dynamically reconfigure itself.
