This locking scheme uses communication protocols such as TCP/IP to exchange locking information. To achieve this, the nodes employ a cluster-wide locking scheme for file system resources.

A GFS2 file system is intended to provide a feature set which is as close as possible to a local file system, while at the same time enforcing full cluster coherency between nodes. The Red Hat Global File System 2 (GFS2) file system is a 64-bit symmetric cluster file system which provides a shared name space and manages coherency between multiple nodes sharing a common block device.
