	  A cluster filesystem.

Allows a cluster of computers to simultaneously use a block device
	  that is shared between them (with FC, iSCSI, NBD, etc...).  GFS reads
	  and writes to the block device like a local filesystem, but also uses
	  a lock module to allow the computers coordinate their I/O so
	  filesystem consistency is maintained.  One of the nifty features of
	  GFS is perfect consistency -- changes made to the filesystem on one
	  machine show up immediately on all other machines in the cluster.

To use the GFS2 filesystem in a cluster, you will need to enable
	  the locking module below. Documentation and utilities for GFS2 can
	  be found here: http://sources.redhat.com/cluster

The "nolock" lock module is now built in to GFS2 by default. If
	  you want to use the DLM, be sure to enable IPv4/6 networking.

	  Multiple node locking module for GFS2

Most users of GFS2 will require this. It provides the locking
	  interface between GFS2 and the DLM, which is required to use GFS2
	  in a cluster environment.
