On node1 login with root account; the ha.cf file needs to be the same on both nodes.
The option “crm no” in the ha.cf specifies heartbeat version 2 to behave as version 1.2.3; this means it is limited to a 2 node cluster.
If you choose to run version 1.2.3 you will need to comment out or delete the “crm no” in the ha.cf
[root@node1]# cd /etc/ha.d
[root@node1]# vi ha.cf
## /etc/ha.d/ha.cf on node1 ## This configuration is to be the same on both machines ## This example is made for version 2, comment out crm if using version 1 keepalive 1 deadtime 5 warntime 3 initdead 20 serial /dev/ttyS0 bcast eth1 auto_failback yes node node1 node node2 crm no # comment out if using version 1.2.3
Copy the ha.cf to node2 so they both have the same configuration file.
[root@node1]# scp /etc/ha.d/ha.cf root@node2:/etc/ha.d/
