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 rebootThe 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 statusThe node rejoins the cluster.
NoteIf any services fail after the reboot, run sudo
pcs resource cleanup, which cleans the errors and sets the state of each resource to
Started. 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.
