We figured out our problem. Turns out one of our switches had a firewall setting that was blocking our multicast. All is working now. Thanks for your help.

Pavlos,
Thanks for helping out on this. We are running on RHEL 5.5 running on the iron and not a VM. We don't have SELinux turned on and the firewall is disabled. Here is information in the /etc/modprobe.conf file.
alias eth0 bnx2
alias eth1 bnx2
alias scsi_hostadapter cciss
alias scsi_hostadapter1 qla2xxx
alias scsi_hostadapter2 usb-storage
alias bond0 bonding
options bond0 mode=1 miimon=100
options lpfc lpfc_lun_queue_depth=16 lpfc_nodev_tmo=30 lpfc_discovery_threads=32
We did take off the bond0 as a test and now only have our IP address assigned to eth0 and still having the same problem when starting corosync. The problem we are finding in the /var/log/cluster/corosync.log file is below.
Sep 30 07:58:57 e-magdb1.buysub.com crmd: [28406]: info: crm_timer_popped: Election Trigger (I_DC_TIMEOUT) just popped!
Sep 30 07:58:57 e-magdb1.buysub.com crmd: [28406]: WARN: do_log: FSA: Input I_DC_TIMEOUT from crm_timer_popped() received in state S_PENDING
Sep 30 07:58:57 e-magdb1.buysub.com crmd: [28406]: info: do_state_transition: State transition S_PENDING -> S_ELECTION [ input=I_DC_TIMEOUT cause=C_TIMER_POPPED origin=crm_timer_popped ]
What could this 'just popped' message mean?
I have no idea about the meaning of this message. But, lets exclude any network issues.
Does the ping between the nodes works?
if you run tcpdump on the interface and then start corosync, do you see musticast packets arriving?
Unfortunately, I don't use corosync so I can't compare your conf with mine, I use heartbeat, so I can't tell if you have any conf issue.
Cheers,
Pavlos
