	  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

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