After you have created your filesystem, you may add it to
/etc/fstab:
/dev/<vg-name>/<lv-name> <mountpoint> gfs defaults 0 0
For a GFS2 filesystem, simply change the defined filesystem type to:
/dev/<vg-name>/<lv-name> <mountpoint> gfs2 defaults 0 0
Do not forget to make this change on both cluster nodes.
After this, you may mount your new filesystem by starting the
gfs service (on both nodes):
service gfs start
From then onwards, as long as you have DRBD configured to start
automatically on system startup, before the RHCS services and the
gfs service, you will be able to use this GFS file system as you
would use one that is configured on traditional shared storage.
