I don't know if o2cb stack can have multiple clusters on the same node. 
With pacemaker
stack, once we setup a pacemaker cluster stack, we can have multiple 
ocfs2 instance, i.e
mkfs and mount multiple ocfs2 FS on the same node.

Why do you want to setup multiple o2cb cluster on the same node?  I 
never know this need
of usage so far :)

Maybe, others can help on your question.

Thanks,
Eric
