Hi,
I think CMAN expect that the names of the cluster nodes be the same returned by the command "uname -n".
For what you write your nodes hostnames are: test01.gdao.ucsc.edu and test02.gdao.ucsc.edu, but in cluster.conf you have declared only "test01" and "test02".

These servers are currently on the same host, but may not be in the future. They are in a vm cluster (though honestly, I'm not sure what this means yet).
SElinux is on, but disabled.
Firewalling through iptables is turned off via system-config-securitylevel
There is no line currently in the cluster.conf that deals with multicasting.
Any other suggestions?

In my environment I had a problem to start GFS2 with servers in differents hosts.To clustering servers, was need migrate one server to the same host of the other, and restart this.
I think, one of the problem was because the virtual switchs.To solve, I changed a multicast IP, to use 225.0.0.13 at cluster.conf<multicast addr="225.0.0.13"/>And add a static route in both, to use default gateway.
I don't know if it's correct, but this solve my problem.
I hope that help you.
Regards.

Hi, Steven.
I've tried just about every possible combination of hostname and
cluster.conf.
ping to test01 resolves to 128.114.31.112
ping to test01.gdao.ucsc.edu resolves to 128.114.31.112
It feels like the right thing is being returned. This feels like it
might be a quirk (or bug possibly) of cman or openais.
There are some old bug reports around this, for example
https://bugzilla.redhat.com/show_bug.cgi?id=488565. It sounds like the
way that cman reports this error is anything but straightforward.
Is there anyone who has encountered this error and found a solution?
