The failover cluster database could not be unloaded and any potentially incorrect changes in memory could not be discarded.  The cluster service will attempt to repair the database by retrieving it from another cluster node.  If the cluster service does not come online, restart the cluster service on this node.  If restarting the cluster service does not fix the problem, please restart the machine.  If the cluster service fails to come online after a reboot, please restore the cluster database from the last backup.  The current database was copied to '%1'.  If no backups are available, please copy '%1' to '%2' and attempt to start the cluster service.  If the cluster service then comes online on this node, some cluster configuration changes may be lost and the cluster may not function properly.  Run the Validate a Configuration wizard to check your cluster configuration and verify that the hosted Services and Applications are online and functioning correctly.
