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

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.
