SPDX-License-Identifier: GPL-2.0 - -==================== -Global File System 2 -==================== - -GFS2 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). GFS2 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 GFS2 is perfect consistency -- changes made to the file system -on one machine show up immediately on all other machines in the cluster. - -GFS2 uses interchangeable inter-node locking mechanisms, the currently -supported mechanisms are: - - lock_nolock - - allows GFS2 to be used as a local file system - - lock_dlm - - uses the distributed lock manager (dlm) for inter-node locking. - The dlm is found at linux/fs/dlm/ - -lock_dlm depends on user space cluster management systems found -at the URL above. - -To use GFS2 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 - -The gfs2-utils package is required on all cluster nodes and, for lock_dlm, you -will also need the dlm and corosync user space utilities configured as per the -documentation. - -gfs2-utils can be found at https://pagure.io/gfs2-utils - -GFS2 is not on-disk compatible with previous versions of GFS, but it -is pretty close. - -The following man pages are available from gfs2-utils: - - ============ ============================================= - fsck.gfs2 to repair a filesystem - gfs2_grow to expand a filesystem online - gfs2_jadd to add journals to a filesystem online - tunegfs2 to manipulate, examine and tune a filesystem - gfs2_convert to convert a gfs filesystem to GFS2 in-place - mkfs.gfs2 to make a filesystem - ============ ============================================= |
