Hyper-v vss writer keeps going away. RRS feed

  • Question

  • Now that I know how to fix the Hyper-v vss writer I need to know how to keep it from dissapearing from vssadmin.

    Every time I tried to do something with DPM on the Host the Hper-v vss writer goes away.

    Is there a patch to solve this problem?

    Thanks

  • Please check the application and system events logs to see if there are any errors associated with this from sources VSS or Volsnap. These will help in determining why the writer is failing and disappearing from the host machine after a failed backup.

  • Hi

    Are you using DPM2010 or DPM 2007. Do you have a stand-alone hyper-v enviroment or are ypu usining a R1 cluster or CSV cluster? Have you verified the needed hotfixes? Look at this link for DPM2010 for pre installed hotfixes: http://technet.microsoft.com/en-us/library/ff399140.aspx

    If your using DPM2007 look at this link: http://technet.microsoft.com/en-us/library/bb808827.aspx

  • I'm using DPM 2007 SP1. The server I'm trying to backup is a 2008 enterprise. Its all pretty standard stuf.

    No clusters.  The server seems to be up to date. I'm not suere about the necessary hot fixes.  Where can I check for these?

     

    thanks

  • I would agree with Robert.  Available hotfixes on the DPM side, recent Hyper-V hotfixes (http://technet.microsoft.com/en-us/library/ff394763(WS.10).aspx) and the most current Integration Components play a big part in your success. 

    A quick fix to restore the Hyper-V writter is to restart the VMMS.exe (Hyper-V Management Service).
