12	  Allows a cluster of computers to simultaneously use a block device
13	  that is shared between them (with FC, iSCSI, NBD, etc...).  GFS reads
14	  and writes to the block device like a local filesystem, but also uses
15	  a lock module to allow the computers coordinate their I/O so
16	  filesystem consistency is maintained.  One of the nifty features of
17	  GFS is perfect consistency -- changes made to the filesystem on one
18	  machine show up immediately on all other machines in the cluster.
19
20	  To use the GFS2 filesystem in a cluster, you will need to enable
21	  the locking module below. Documentation and utilities for GFS2 can
22	  be found here: http://sources.redhat.com/cluster
23
24	  The "nolock" lock module is now built in to GFS2 by default. If
25	  you want to use the DLM, be sure to enable IPv4/6 networking.
