After you complete the following steps, all groups you move to cluster node 1 are moved back to the active cluster node 2.
ScenarioNode1 has the groups and is paused. The failback policy says Node1 is Preferred Owner. The resources will stay on Node1 and will stay online. Node2 is restarted. After Node2 starts, the Cluster service sees that there is now an Active non-paused node so it moves the groups over.
This behavior occurs because when the active cluster node starts, the Cluster service enumerates all the groups and resources. If the Cluster service finds a failback policy, the group or groups are moved depending on the failback policy settings. However, if cluster node 1 is paused and cluster node 2 is not paused, all the groups are moved to cluster node2. Pause state takes precedence over a failback policy. The node is actively participating in cluster operations but cannot take ownership of resource groups and cannot bring resources online
To work around this behavior, resume the paused cluster node before you restart the active cluster node. To do this, follow these steps:
