An os-refresh-config on the controller node should bring it back. The reboot, sometimes, does not bring up all the services in the right order.

Another question: Last time I rebooted the Overcloud, and the 169.254.169.254 route was gone, is this normal ? It is supposed that for every reboot 169.254.169.254 route exists, right ? Maybe its OS image issue or something else ?
