After running the gfs_jadd command, you can run the gfs_tool df MountPoint command

again to check that the new journals have been added to the file system.

Examples

In this example, one journal is added to the file system that is mounted at the /mnt/gfs

directory. The underlying logical volume for this filesystem is extended before the journal can be

added.

[root@tng3-1 ~]# lvextend -L35G /dev/gfsvg/gfslv

Extending logical volume gfslv to 35.00 GB

Logical volume gfslv successfully resized

[root@tng3-1 ~]# gfs_jadd -j1 /mnt/gfs

FS: Mount Point: /mnt/gfs

FS: Device: /dev/mapper/gfsvg-gfslv

FS: Options: rw,hostdata=jid=0:id=196609:first=1

FS: Size: 5242877
