I'm trying to add a cluster node to a Windows Server 2012 cluster. This system was part of an old cluster that has since been destroyed and the system upgrade from 2008R2 to 2012. I cannot add the system to the cluster because I keep getting these errors on the node when I do so. Any idea on how to release the drive "Unknown Device"? I've already tried restarting, and adding and removing the Failover Cluster feature. The result is the same.
PS> Clear-ClusterNode -force
Clear-ClusterNode : Failed to invoke the cleanup module on node NODE4.
The device is not ready. (Exception from HRESULT: 0x80070015)
In event viewer:
Event ID 4611
Clustered disk with ID 'Unknown Device' was not released by the Partition Manager while destroying the cluster. The error code was '21'. Restarting the machine will ensure the disk is released by the Partition Manager.
