help
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/gfs/

config GFS2_FS_LOCKING_NOLOCK
tristate "GFS2 \"nolock\" locking module"
depends on GFS2_FS
help
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.

config GFS2_FS_LOCKING_DLM
tristate "GFS2 DLM locking module"
depends on GFS2_FS
select DLM
help
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.
