Hi Aaron,

I am getting this output..
$ sudo pcs status resources $ sudo pcs cluster stop http_server

floating_ip (ocf::heartbeat:IPaddr2): Started hacluster1 http_server (ocf::heartbeat:nginx): Started hacluster2 Error: nodes 'http_server' do not appear to exist in configuration
In that case, how do I test, I am not able to switch between these.

Please help.

Regards,
zain

I’m not 100% about my answer, but we have 10.10 and 10.1 as nginx client, and for the front end the address will be 10.20, it means that our servers can have any ip address, the browser will always receive the requests as 192.168.10.20 and nginx will forward the requests to Node1: 192.168.10.10 or Node2: 192.168.10.1 depending on the availability.
