I configured two lvs keepalived servers. The first is master server, ip 10.1.88.76, iptables closed. The second is backup server, ip 10.1.88.77, iptables closed. the network connection between two servers is ok (verified by ping)
But, the problem is both servers are in MASTER state. What I expect is one in Master and the other in BACKUP mode.
What should I do to settle the problem? Thank you
