[Ocfs2-users] Adding new nodes to OCFS2?

[Ulf Zimmermann]

I actually did the below command (for node 2 and 3), it added it to the
/etc/ocfs2/cluster.conf but as far I could tell, it didn't allow me to
actually mount then on node 2 or 3. But as I had to do some other work
(resize another volume) I ended up rebooting and got them added that
way.
