QuestionCan't stop merging

    Hello, I'm running into a huge problem with merging on HYPER-v on server 2008 R2.

    I started merging to recover some disk space, but didn't know that HYPER-V needed disk space to do the merge, so now I would like to cancel.  When I right click on the virtual machine and click on cancel merge I get the following error message "you do not have permission to perform the operation."

    but I am an admin. My user account is a member of the following groups

    administrators
    dchp administrators
    dhcp users
    domain admins
    domain users
    drive admins
    enterprise admins
    group policy creator owners
    schema admins
    users

    Any ideas, or is there a group that I should add myself too, to stop this.

    P.S. reboots and stopping/starting the virtual service doesn't help

    Sorry for the late answer.

    Can you tell about how did you start the merge? Are you referring to the auto-merge operation for the deleted snapshot disks? Currently there is no way of blocking auto merge that is initiated by Hyper-V for the disks of deleted snapshots.

    Also one thing to note, merging does not always saves disk space. If the child VHD contains information which is not available in the parent VHD, merged disk will basically have the sum of sizes of the disks that are merged.

    Yes I am referring to the auto-merge operation for deleted snapshots.  But is there a way to stop the merging process, otherwise I need to play musical chairs with data to free up enough space for the operation to work?
