Did you check if multicast is enabled on the network switch and working
properly? That's generally the first thing people forget to look.

A simple test would be to switch to udpu transport (TechPreview in
rhel6.1) and see if that solves the issue, effectively isolating the
problem to multicast on the switch.

It might be useful if you can enable debugging and collect
/var/log/cluster/corosync.log from all 3 nodes.


PS It's easy to test with iptables off. and check logs for possible avc
denials (selinux) just in case we missed something during out tests.
