+         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, you will need to enable one or more of
+         the below locking modules. Documentation and utilities for GFS2 can
+         be found here: http://sources.redhat.com/cluster

+       help
+         Single node locking module for GFS2.
+
+         Use this module if you want to use GFS2 on a single node without
+         its clustering features. You can still take advantage of the
+         large file support, and upgrade to running a full cluster later on
+         if required.
+
+         If you will only be using GFS2 in cluster mode, you do not need this
+         module.

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