“Management Interface: VHD Error” with PVS and DFSR

Written by Ingmar Verheij on July 5th, 2013. Posted in Citrix, Provisioning Server

You might encounter the following error when you use Microsoft DFSR to replicate the vDisk store in your Citrix PVS when uploading a vDisk:

Management Interface: VHD Error

Using a staging vDisk store helps preventing this error.

DFSR

This message is thrown when the vDisk is uploaded to a store that’s provided by multiple servers (and replicated via DFSR). There could be two reasons this happens:

  • DFSR started replicating the initial (empty) files and, as a result, temporary locks the file preventing the vDisk to be uploaded;
  • Your machine got connected to a different streaming server but the files aren’t replicated yet (as explained by Bram Wolfs).

 

Solution

To prevent his situation you can create a separate vDisk store that’s provided by a single server (not replicated by DFSR) and copy the vDisk after uploading.

 

Other resources

Other reasons for the same error message could be:

  • You have a NetApp and the CIFS Max Multiplex was set too high (see CTX132458)
  • The vDisk store is placed on storage with a FAT file system instead of NTFS (see CTX133042)
