failed to authenticate cluster nodes using pacemaker on centos7

Question

I am trying to configure two node(node1 and node2 HA cluster using pacemaker on centos 7. I executed below steps on both nodes

yum install pcs

systemctl enable pcsd.service pacemaker.service corosync.service

systemctl start pcsd.service

passwd hacluster

After that execute below command on node1

pcs cluster auth node1 node2

i am getting below error

Error: Unable to communicate with node2 Error: Unable to communicate with node1

I have also verified that both nodes are listening on port 2224 and also used telnet to verify that both nodes are able to connect to each other on 2224.

Need help.

Answer 1

The issue got resolved after using FQDN instead of hostname(node1.demo.in, node2.demo.in). below command worked fine.

pcs cluster auth node1.demo.in node2.demo.in

Don't know exact cause for this. Any Idea?
