During a migration a customer build a new Fileserver and attached the old disks from the old Fileserver to the new one.
After attaching the virtual disc the access to the files was not possible on the new Server.
If the disk was attached back, the access is working without any problems.
In this case the Role for Data Deduplication was not installed. After installing the access to the data was also possible on the new Server
