4.2.5. Restoring the CIB

Note

You should only proceed with this step if

Heartbeat is still stopped on all cluster nodes, and
all cluster nodes have had their CIB contents wiped. If you still have remaining nodes that have a residual CIB configuration, proceed as outlined in Section 4.2.4, “Wiping files related to the CRM”.

Restoring the CIB means copying the CIB backup described in Section 4.2.2, “Backing up the CIB” to the /var/lib/heartbeat/crm directory.

# cp ~/cib.xml /var/lib/heartbeat/crm/cib.xml
# chown hacluster:haclient /var/lib/heartbeat/crm/cib.xml
# chmod 0600 /var/lib/heartbeat/crm/cib.xml

You must perform this step on one node only, namely the first node on which you are about to upgrade the cluster software. On all other nodes, the /var/lib/heartbeat/crm directory must remain empty — Pacemaker distributes the CIB automatically.
