To reboot the Ceph Storage nodes, follow this process:
- Select the first Ceph Storage node to reboot and log into it.
- Disable Ceph Storage cluster rebalancing temporarily:
$ sudo ceph osd set noout $ sudo ceph osd set norebalance - Reboot the node:
$ sudo reboot - Wait until the node boots.
- Log into the node and check the cluster status:
$ sudo ceph -sCheck that thepgmapreports allpgsas normal (active+clean). - Log out of the node, reboot the next node, and check its status. Repeat this process until you have rebooted all Ceph storage nodes.
- When complete, enable cluster rebalancing again:
$ sudo ceph osd unset noout $ sudo ceph osd unset norebalance - Perform a final status check to make sure the cluster reports
HEALTH_OK:$ sudo ceph status
