I came into an IT position at a company using Hyper-V, I didn't do any of the setup for Hyper-V, but after a paused-critical situation with Hyper-V last week I am trying to figure out how to get past the situation I am in now with one particular Virtual server.
I have a server running Windows Server 2008 Enterprise and it runs 4 Hyper-V virtual servers on it. One server is the exchange server and that is the server I am having the problem with:
I cannot delete, delete subtree, or export on this virtual server. I get the generic Snapshot failed to delete error and then it lists a virtual ID for which there is a folder, but NOT an avhd file ( I can only assume that it was deleted by the last IT person and the server has been running off of snapshots since.) I have an AVHD file that is currently over 800GB and needs to be merged with it's parent VHD file.
The server is running now and doesn't have any noticeable issues other than failures mentioned above with snapshots/merges/exports. I can create a new snapshot with no problem and I can also reboot the server with no issues....
What can I do to address this deleted AVHD file (yes I tried using recovery software in order to find the deleted file) and the lack of ability to delete/merge snapshots or export this particular virtual machine.
