Abstract
A global mount mechanism capable of maintaining a consistent global name space in a distributed computing system including a plurality of nodes interconnected by a communications link is herein disclosed. The global mount mechanism mounts a new file system resource into the global name space in a coherent manner such that the new file system resource is mounted at the same mount point concurrently in each node. The global mount mechanism accommodates mount or unmount requests initiated from a requesting node for a resource located in a remote node. The global mount mechanism is also used to unmount a file system resource from the global name space. The global mount mechanism also includes an initialization procedure that is used to generate the global name space initially by providing each local mount point with a global locking capability.
