Hello,
I have a working 2 node cluster that I am trying to add a third node
to. I am trying to use Red Hat's conga (luci) to add the node in but
If you have two node cluster with two_node=1 in cluster.conf - such as
two nodes with no quorum device to break a tie - you'll need to bring
the cluster down, change two_node to 0 on both nodes (and rev the
cluster version at the top of cluster.conf), bring the cluster up and
then add the third node.
For troubleshooting any cluster issue, take a look at syslog
(/var/log/messages by default). It can help to watch it on a
centralized syslog server that all of your nodes forward logs to.

Thank you for the response. /var/log/messages doesn't have any
errors. It says cman started then says can't connect to cluster
infrastructure after a few seconds. My cluster does not have the
two_node=1 config now. Conga took that out for me. That bit me last
night because I needed to put that back in.
CMAN still will not start and gives no debug information. Anyone know
why cman_tool -d join would not print any output at all?
Troubleshooting this is kind of a nightmare. I verified that two_node
is not in play.
If cman_tool join -d doesn't produce any output then the most likely
problem is a mismatch between the cman and openais versions. Because
cman is a configuration module for openais it loads very early in the
initialisation sequence.
If you are sure the versions are right (ie they match those on the
running nodes of the cluster) then do
# strace -f cman_tool join -d
and post the results here and I'll have a look for you.
