Symptoms

Consider the following scenario:

  • You have a Windows Server 2008 R2 failover cluster in a network.

  • You create some groups. For example, you create four groups.

  • You add the same string to the AntiAffinityClassNames common property of all the groups, and then move the groups to the same node.

  • You perform one of the following operations:

    • You stop and then start a node.

    • You evict and then add a node.

In this scenario, the AntiAffinityClassNames property does not work, and all anti-affined groups are moved to the new node. You expect that either the groups should not be moved, or that only one group is moved to the new node.

Cause

This issue occurs because the algorithm that is used to determine the destination node does not honor the AntiAffinityClassNames property.
