As I don't have your cluster.conf or access to your DNS server it's hard to say
from here, but that message does mean what it says. If you have older software
it might not detect anything other than the node's main hostname, but later
versions will check all the interfaces on the system for something that matches
anything in cluster.conf.

I see you're using eth1 so make sure you do have an up-to-date cman.
