A method, system and apparatus of a file locking within a network file system federated namespace is disclosed. In one embodiment, a method includes accessing a target file in a storage medium over a network through an intermediate proxy server using a processor. The storage medium may be any one storage medium of a group of storage mediums on the network forming a data sharing cluster. In addition, the method includes locking the target file in the storage medium through a lock protocol to enable an access to modify the target file to at most one user at any given time, via the intermediate proxy server.

System and method of file locking in a network file system federated namespace

The present invention provides a system and method for abstracting multiple network attached storage ('NAS') locations, providing a single global namespace and a single mount point that is protocol and location-independent. As a result, rather than identifying each NAS and file server by location, access is provided through a single transparent mechanism. In order to maintain transparency, the present invention provides a way to reconcile the different naming practices for different file server protocols.
