12 | A cluster filesystem. |
13 | |
14 | Allows a cluster of computers to simultaneously use a block device |
15 | that is shared between them (with FC, iSCSI, NBD, etc...). GFS reads |
16 | and writes to the block device like a local filesystem, but also uses |
17 | a lock module to allow the computers coordinate their I/O so |
18 | filesystem consistency is maintained. One of the nifty features of |
19 | GFS is perfect consistency -- changes made to the filesystem on one |
20 | machine show up immediately on all other machines in the cluster. |
21 | |
22 | To use the GFS2 filesystem in a cluster, you will need to enable |
23 | the locking module below. Documentation and utilities for GFS2 can |
24 | be found here: http://sources.redhat.com/cluster |
25 | |
26 | The "nolock" lock module is now built in to GFS2 by default. If |
27 | you want to use the DLM, be sure to enable HOTPLUG and IPv4/6 |
28 | networking. |

34 | Multiple node locking module for GFS2 |
35 | |
36 | Most users of GFS2 will require this. It provides the locking |
37 | interface between GFS2 and the DLM, which is required to use GFS2 |
38 | in a cluster environment. |
