Can you please clarify this?
On my cluster:
uname -n == /etc/hosts entry for eth0 (public address)
cluster.conf "clusternode name" entries == /etc/hosts entry for eth1 (private network)
and the cman daemon starts just fine. Is there something that I'm missing, or
will this cause other issues?
I'm running CentOS 5, cman-2.0.73-1.el5_1.1.

Wow...that value really seems like an ideal candidate for inclusion in the
cluster.conf file, or in :
/etc/sysconfig/cman
