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.
