It's most likely a host name problem, because I run a two node cluster,
and I used fence_node while testing everything.

If you post the relevant sections of your cluster.conf file (the
clusternodes, and fencedevices sections are the important ones)  We
might be able to help you figure out why it's not working right though.

But mainly, check that the names you use in the clusternode name
attributes are resolvable on both nodes, and they resolve to the same IP
address on both nodes.

Hmm, I'll see if I can replicate this on my testing cluster.  Although I
don't think it's designed to work the way you're expecting it to from
your config.  Of course, I haven't played with multiple fence devices in
my configs before, so I could be mistaken.
