A method of providing shared objects and node-specific objects in a cluster file system is described and provided. The method includes providing to a particular shared object an attribute, whereas the particular shared object can be a container-type shared object. The attribute indicates any object created in the particular shared object (including its sub-divisions or sub-containers) from this point in time will be designated as node-specific. Furthermore, when a node causes a file system operation that is node-specific to be performed by accessing the particular shared object, the file system operation is performed in an alternate directory corresponding to the node. The alternate directory supports a node-specific object. The shared objects and the node-specific objects can be directories. Additionally, the shared objects and the node-specific objects can be files.

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.
