Two Zabbix 2.4 servers using CentOS 6.6 with an external MySQL DB, both servers are configured to connect to this DB when they are running.

I followed a combination of Zabbit High Availability guide and the Quickstart from Clusterlabs. I think I have finished the setup since when I do a failover (node1 to node2) the virtual IP is assigned to Active node and the zabbix-server service also starts running.

However, the web interface says Zabbix server is not running. I don't see any errors or warnings in the log file. When I fail back to node1, everything is fine and web ui says zabbix server is running.

*********** This is the node where Zabbix server is fine
[root@zabbixserver3 ~]# netstat -ntap | grep 10051

I found the issue. It was a very elusive typo in /etc/zabbix/web/zabbix.conf.php

I got one character wrong in server name!
