Hyper V - VHD files not found RRS feed

  • Question

  • We are running Windows server 2008 R2 with Hyper-V.  Have two instances of differnt VM's running, but one (workamajig) now cannot find .VHD or snapshot files. Have tried a data recovery and extensive searches for the file, but nowhere on any of the drives, although, the other VM is working fine. Any insight into what may have caused, or recommendations on tracking down where the files may have went? Oh yeah, no backup .VHD to work with.

    Below are the sequence of warnings and errors from event log all within 5 minutes of each other.

    ---------

    'workamajig' successfully allocated memory, but a subset of the physical pages was allocated on a remote non-uniform memory architecture (NUMA) node. This configuration is not recommended because it will reduce performance. (Virtual machine ID BF5C6880-DED7-4DB4-851F-7F108EC8519B)

    Hyper-V VSS writer cannot identify the virtual machine with ID 'BF5C6880-DED7-4DB4-851F-7F108EC8519B'. Please check if there are any corrupt or invalid configuration files and try again.

    ----------

    Around the same time, Backup Assist and Acronis Drive Monitor looked like they were being installed and ran (within few minutes of these errors). Any known issues with compatibility? Deal is that we had a local IT firm that was to get some backups running, but, these "missing" files are not even in the first backup that happened 10 minutes after the last error.

  • Never did find the root of the problem on this, and yes, the VM was running previously. I did end up finding a backup of the "G" drive, and restored. Just completely odd how the files just completely disappeared in the first place. I appreciate everyones suggestions.

    Check permission setting here http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/fbf80eb7-9a8b-48c2-9611-15fac92de89e But it looks like that the VHD's are on a remote location not on that hyper-v machine.

    Where is "G:"?

    Verify the permissions on both the root G: and 'G:\workamajig\'

    Hyper-V is unable to access that folder as indicated in the error.

  • Phillip and Adelino...

    The "G:" drive is 300GB partition from a 4 stack drive set on the same root machine as hyper V, but dedicated to this VM. I have checked permissions and administrators and system have full control. I also ran the ICACLS command, although I can still see the VM within Hyper-V, still CANNOT start it. "the system cannot find the specified file" (vhd).

  • Hi,

     

    You mentioned there are 2 VMs running on the Hyper-V machine, so please help me to collect the following information:

     

    1. Have you ever been able to start the problematic VM 'workamajig'?

    2. Did you store another VM on the same G: drive?

     

    By the way, please also try to disable or uninstall “Backup Assist and Acronis Drive Monitor” to see whether you can resolve the issue.

     

     

    Best Regards,

    Vincent Hu
