4.2.7. Restarting Heartbeat services
First, restart Heartbeat on the node where you restored the CIB (see
Section 4.2.5, “Restoring the CIB”) with
/etc/init.d/heartbeat start. Then, repeat this command on the remaining cluster nodes. At this time,
the cluster is still in unmanaged mode (meaning it does not start, stop, or monitor any resources),
the cluster redistributes the old CIB among its nodes, and
the cluster is still using the pre-upgrade CIB schema.
