    • A system and method for acquiring, releasing, and reclaiming a lock of a data structure in a network file system (“NFS”) is disclosed. Generally, a text file is created in a management library of the data structure. The name of the text file comprises an identifier of the lock, an identifier of a process attempting to acquire the lock, and an identifier of a machine on which the process attempting to acquire the lock is running. The identifier of the process attempting to acquire the lock and the identifier of the machine on which the process attempting to acquire the lock is running is saved in the contents of the text file and a hard line is created pointing to the text file. Finally, a number of links pointing to the text file is determined and a lock of the data structure is granted based on the number of links pointing to the text file.
