I have a working CentOS 5.5/RHCS cluster in order to support a simple
GFS2 filesystem (ontop of DRBD) between 2 nodes.

Since the two nodes have multiple network interfaces, I'd like to tie
all cluster communication to ETH2 as ETH0 is my production-facing interface.

I understand I can partially achieve this by using a hostname mapped
(via /etc/hosts) to the IP address of ETH2 in cluster.conf.
This seems to work for OpenAIS; the multicast address it uses is bound
to to eth2 according to "ip maddress show dev eth2", but ccsd is still
listening on 0.0.0.0 for various ports according to netstat.

How can I force ccsd to use ETH2?

Regards,

Mark.
