Symptoms
Consider the following scenario:
-
You configure a failover cluster that consists of servers that are running Windows Server 2008 R2.
-
You create a cluster shared volume (CSV) that includes some virtual machines that are owned by different cluster nodes.
-
You back up the virtual machines by using a Volume Shadow Copy Service (VSS) hardware provider. For example, you back up a protection group in Microsoft System Center Data Protection Manager (DPM) 2010.
-
The owner of the CSV changes during the backup process.
In this scenario, the CSV logical unit numbers (LUNs) enter a failed state, and do not come online on the next cluster node. Therefore, the backup process fails.
Notes
-
This issue does not occur if you do not use a VSS hardware provider to back up the virtual machines.
-
This issue does not occur if the change of owner of the CSV is not triggered during the backup process.
Cause
This issue occurs because the Cluster service incorrectly accesses stale information to determine whether a CSV LUN is in the correct state to start the backup process.
