Hi Roland,

We just attempted to repro this and were not successful. Can you please provide more details?

If you could provide your repro steps?
Also, if you run Get-ClusterLog and look at the C:\Windows\Cluster\Reports for the Cluster.log there will be additional details in regards to the failure. If you could post what you are seeing logged to the Cluster.log it would be helpful

Thanks!!
