[Ocfs2-users] problem mounting ocfs2: heartbeat

[Sunil Mushran]

Oh... I need to relook the doc.

All you need to do is:
1. Start the cluster using:
/etc/init.d/o2cb start

2. mount the volume:
mount -t ocfs2  /dev/sdX /dir

Do an lsmod and ensure that all modules have been unloaded
before starting the cluster. Also, run "/.../o2cb configure"
to specify your cluster name.

Other o2cb commands are "load" to just load the modules
and "online" to start the cluster. (start = load + online)
