+ 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 HOTPLUG and 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.
