Abstract
Machine implemented method and system for a networked storage system having a first storage system node providing storage space to a client computing system at a first storage device and a second storage system node managing a second storage device are provided. A lock is granted by the first storage system node to the client computing system for accessing a data container stored at the first storage device. The first storage system node updates a lock data structure for managing the lock granted to the client computing system. Information regarding the lock is then replicated at the second storage system node, such that the second storage system node can recover the lock, when the first storage system node becomes unavailable and the second storage system node takes over the first storage device to interface with the client computing system.
