Ensure to have the supported versions of OpenShift Container Platform with Red Hat Gluster Storage Server and Red Hat Openshift Container Storage. For more information on supported versions, see Section 3.1.1, “Supported Versions”

If Heketi is running as a standalone service in one of the Red Hat Gluster Storage nodes, then ensure to open the port for Heketi. By default the port number for Heketi is 8080. To open this port execute the following command on the node where Heketi is running:

# firewall-cmd --zone=zone_name --add-port=8080/tcp
# firewall-cmd --zone=zone_name --add-port=8080/tcp --permanent

If Heketi is configured to listen on a different port, then change the port number in the command accordingly.
