You have to give your cluster 2 node setting on remaining two nodes.
How can I define a two-node cluster if a majority is needed to reach
quorum?
We had to allow two-node clusters, so we made a special exception to
the quorum rules. There is a special setting "two_node" in
the /etc/cluster.conf file that looks like this:
<cman expected_votes="1" two_node="1"/>
This will allow one node to be considered enough to establish a
quorum. Note that if you configure a quorum disk/partition, you don't
want two_node="1".

Yeah I know how to set up two_node cluster, but didn't know that
reconfiguration is the only way out when one node is missing :( I'm
disappointed with this limitation, I hope that developers will sort it
out for RHEL6 :(
I think your so called 'limitation' is more related to mistakes that was
made during the planing phase of your cluster setup than to missing
functionality.
Please take a look at the qdisk manpage and aditionaly to the cman faq
sections about tiebraker, qdisks and especially the last man standing
setup...
