Could not lock all volumes. Clustered disk group was not deported
This message appears if a handle is present on a volume that is located on one of the disks within the DG, when the deport operation is initiated.
Close any application or process that is maintaining a handle on the volume.
If the same error is reported even after the hosted application is closed, then a Microsoft utility: handle.exe can be used to determine which process is still maintaining a handle on the volume.
The tool is available at Handle v5.0
