10.2. Rebooting Controller Nodes
To reboot the Controller nodes, follow this process:
- Select a node to reboot. Log into it and reboot it:
$ sudo reboot
The remaining Controller Nodes in the cluster retain the high availability services during the reboot. - Wait until the node boots.
- Log into the node and check the cluster status:
$ sudo pcs status
The node rejoins the cluster.Note
If any services fail after the reboot, run sudopcs resource cleanup
, which cleans the errors and sets the state of each resource toStarted
. If any errors persist, contact Red Hat and request guidance and assistance. - Log out of the node, select the next Controller Node to reboot, and repeat this procedure until you have rebooted all Controller Nodes.
