^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 	  Allows a cluster of computers to simultaneously use a block device
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 	  that is shared between them (with FC, iSCSI, NBD, etc...).  GFS reads
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 	  and writes to the block device like a local filesystem, but also uses
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 	  a lock module to allow the computers coordinate their I/O so
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) 	  filesystem consistency is maintained.  One of the nifty features of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) 	  GFS is perfect consistency -- changes made to the filesystem on one
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 	  machine show up immediately on all other machines in the cluster.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 	  To use the GFS2 filesystem in a cluster, you will need to enable
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) 	  the locking module below. Documentation and utilities for GFS2 can

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) 	  you want to use the DLM, be sure to enable IPv4/6 networking.
