[Ocfs2-users] Using multiple clusters on the same host

[Angelo McComis]

I can confirm what Brian is saying...  I have a cluster that looks
like this:

Nodes a/b/c/d/e/f: sharing vol1
Nodes c/d/e/f: sharing vol2
Cluster.conf contains definitions for a-f.

Although, in Brian's example, nodes e/f/g never share volumes with the
others, so it wouldn't necessarily have to be part of the cluster.conf
that a-d is part of.
