pcs running but status shows resources stopped

  • 772

My first time setting up pcs. I have two CentOS 7 VM's on which I installed pcs and Pacemaker. I defined a virtual IP and Apache HTTP cluster.

The two VM's have IP's 192.168.56.121 and 192.168.56.122. The VIP is configured for 192.168.56.199. I can ping the VIP and can open the test index.html on the VIP.

As per another post here, I have stopped and disabled httpd.service as pcs manages its operations. firewalld is disabled as is SELinux.

I have two issues: Firstly, my index.html on the two nodes is a single line of text saying "Node 1" and "Node 2". Refreshingly the page multiple times, I see that only the node 1 file is served unless I stop that node, in which case the file from node 2 is served. This indicates that the nodes are working as active-standby. Any way to make it a load-balancer with both nodes serving alternate requests?

Secondly, the pcs status shows that the resources are in stopped state, even though ping and http are working.

Here is what pcs status shows:
