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 interchangeable inter-node locking mechanisms, the currently -supported mechanisms are: - - 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/ - -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 - -If you are using Fedora, you need to install the gfs2-utils package -and, for lock_dlm, you will also need to install the cman package -and write a cluster.conf as per the documentation. For F17 and above -cman has been replaced by the dlm package. - -GFS2 is not on-disk compatible with previous versions of GFS, but it -is pretty close. - -The following man pages can be found at the URL above: - 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 |
