Eric,
General question. I tried to set up a cman + corosync + pacemaker cluster using two corosync rings. When I start the cluster, everything works fine, except when I do a 'corosync-cfgtool -s' it only shows one ring. I tried manually editing the /etc/cluster/cluster.conf file adding two <interface>
AFAIK cluster.conf should be edited so altname is used. So something
like in this example:

I don't think you have to add altmulticast.

sections, but then cman complained that I didn't have a multicast
address specified, even though I did. I tried editing the
/etc/corosdync/corosync.conf file, and then I could get two rings, but
the nodes would not both join the cluster. Bah! I did some reading and
saw that cman didn't support multiple rings years ago. Did it never get
updated?
