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 in a cluster, you will need to enable
|
|
|
|
the locking module below. Documentation and utilities for GFS2 can

The "nolock" lock module is now built in to GFS2 by default. If

|
|
|
you want to use the DLM, be sure to enable IPv4/6 networking.

Most users of GFS2 will require this. It provides the locking

|
|
|
interface between GFS2 and the DLM, which is required to use GFS2

in a cluster environment.
