Figure 14 Rotating Standby Configuration after Failover
NOTE: Under the min_package_node policy, when node2 is repaired and brought
back into the cluster, it will then be running the fewest packages, and thus will become
the new standby node.
If these packages had been set up using the configured_node failover policy, they
would start initially as in Figure 13, but the failure of node2 would cause the package
to start on node3, as shown in Figure 15.
