Oracle Linux: PaceMaker Cluster Fails To Authorize: "Error: Unable to communicate with <node>"
(Doc ID 2393647.1)
Last updated on AUGUST 04, 2018
Applies to:Linux OS - Version Oracle Linux 7.4 with Unbreakable Enterprise Kerne [4.1.12] and later
Configuring a PaceMaker cluster fails because the authorization does not complete. The firewalld ports had been opened and authorization continued to fail. Authorization still failed with the firewall disabled.
$ sudo pcs cluster auth node1 node2
Error: Operation timed out
Error: Unable to communicate with node2
Node2 responds to ping(1) attempts and nc(1) can connect to host2 port 2224. Connection to the authorization still fails by timing out:
$ unset http_proxy
$ unset https_proxy
$ curl --insecure https://node2:2224/remote/check_auth
curl: (28) Operation timed out after 300363 milliseconds with 0 out of 0 bytes received
# unset http_proxy
# unset https_proxy
# curl --insecure https://node2:2224/remote/check_auth
This is a new deployment of a two-node Corosync/Pacemaker cluster.
