When you configure a highly available application or service in a Windows Server 2008 failover cluster, the group failover threshold value is incorrect. The default value is set equal to the number of nodes that are configured in the cluster.
For example, in a five-node cluster, any highly available application or service resource grouping has a default failover threshold set equal to five. By default, the Period: (hours): setting is set to six hours. Therefore, when a highly available service or application group experiences a failure of one or more resources in the group, the service or application group tries to fail the group over to another node in the cluster up to five times in a six-hour period. After the fifth failover attempt, the service or application group remains in a "Failed" state.
In this situation, a total of n - 1 failovers occurs in the six-hour period. Therefore, four failovers occur. The failover process works correctly. However, the number that appears in the Failover Cluster Management snap-in is incorrect. In this situation, the number is 5.
No adverse effect is associated with the incorrect display in the Failover Cluster Management snap-in. Failover continues to function correctly. No action is required.
This is a known issue in Windows Server 2008 Failover Clustering. This problem is corrected in Windows Server 2008 R2.
