Environment : Red Hat Enterprise Linux 5.6, RHCS
Error : subject line
Issue : I am not sure while I got this error in the system log since quorate is enabled and working fine on non-firewalled machine where SELinux is also disabled. For the two node cluster, all the cluster.conf are same. One node was connected to the cluster and other didn't.
1. Make sure : chkcofing cman off; chkcofing clvmd off; chkcofing rgmanager off;
2. Make sure all cluster.conf fules are same.
3. Check if iptables are temporary off
4. Start cman, clvmd and rgmanager manually one by one
I rebooted whole node and it worked like charm :)
