Global File System

------------------



http://sources.redhat.com/cluster/



GFS is a cluster file system. It 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

file system, but also uses a lock module to allow the computers coordinate

their I/O so file system consistency is maintained.  One of the nifty

features of GFS is perfect consistency -- changes made to the file system

on one machine show up immediately on all other machines in the cluster.



GFS uses interchangable inter-node locking mechanisms.  Different lock

modules can plug into GFS and each file system selects the appropriate

lock module at mount time.  Lock modules include:



  lock_nolock -- allows gfs to be used as a local file system



  lock_dlm -- uses a distributed lock manager (dlm) for inter-node locking

  The dlm is found at linux/fs/dlm/



In addition to interfacing with an external locking manager, a gfs lock

module is responsible for interacting with external cluster management

systems.  Lock_dlm depends on user space cluster management systems found

at the URL above.



To use gfs as a local file system, no external clustering systems are

needed, simply:



  $ mkfs -t gfs2 -p lock_nolock -j 1 /dev/block_device

  $ mount -t gfs2 /dev/block_device /dir



GFS2 is not on-disk compatible with previous versions of GFS.



The following man pages can be found at the URL above:

  gfs2_fsck	to repair a filesystem

  gfs2_grow	to expand a filesystem online

  gfs2_jadd	to add journals to a filesystem online

  gfs2_tool	to manipulate, examine and tune a filesystem

  gfs2_quota	to examine and change quota values in a filesystem

  mount.gfs2	to help mount(8) mount a filesystem

  mkfs.gfs2	to make a filesystem
