- 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 GFS filesystem, you will need to enable one or more of
- the below locking modules. Documentation and utilities for GFS can
- be found here: http://sources.redhat.com/cluster
