required for each node that mounts the file system. (More journals than are needed can be

specified at creation time to allow for future expansion.)

BlockDevice

Specifies a volume.

Examples

In these examples, lock_dlm is the locking protocol that the file system uses, since this is a

clustered file system. The cluster name is alpha, and the file system name is mydata1. The file

system contains eight journals and is created on /dev/vg01/lvol0.

[root@ask-07 ~]# gfs_mkfs -p lock_dlm -t alpha:mydata1 -j 8 /dev/vg01/lvol0

This will destroy any data on /dev/vg01/lvol0.
