Chapter 6. Enable cluster to auto-start after reboot

The cluster is not yet enabled to auto-start after reboot. System admin needs to manually start the cluster after the node is fenced and rebooted.

After testing the previous section, when everything works fine, enable the cluster to auto-start after reboot:

[root@s4node1]# pcs cluster enable --all

Note: In some situations it can be beneficial not to have the cluster auto-start after a node has been rebooted. For example, if there is an issue with a filesystem that is required by a cluster resource, and the filesystem needs to be repaired first before it can be used again, having the cluster auto-start can be a failure because the filesystem doesn’t work. This can cause even more trouble.

Now please rerun the tests in the previous section to make sure that the cluster still works fine. Please note that in section 5.3, there is no need to run command pcs cluster start after a node is rebooted. Cluster should automatically start after reboot.

By this point you have successfully configured a two-node cluster for ENSA2. You can either continue with intensive testing to get ready for production or optionally add more nodes to the cluster.
