     10	  A cluster filesystem.
     11
     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.

     33
     34	  Most users of GFS2 will require this. It provides the locking
     35	  interface between GFS2 and the DLM, which is required to use GFS2
     36	  in a cluster environment.
