HyperV server almost full

I have a HyperV Host Server that has 2 Virtual Servers installed on it. The AVHD or snapshots have filled it up.

How can I free up space, I have tried deleting the Snapshots but my C Drive is still full.

I have turned off the Virtual Servers but C Drive still full.

Any help would be great.

I’ve tried to delete snapshots, but they failed to merge because there is not enough space on the disk (error 0x80070070). What can I do?

If possible, free up storage space on the volume where the .vhd file is located. In some cases this might not be possible. For example, the space is occupied by .vhd and .avhd files only. If you cannot free up space on the current volume, export the virtual machine to a volume that has sufficient disk space to allow the merge to complete. The process of exporting the virtual machine to delete snapshots consists of the following steps:

   1. Export the virtual machine from the current location.

   2. Import the virtual machine to a location that has sufficient storage space. The location should be a different volume on the same host to avoid configuration problems.

   3. If the version of Hyper-V is earlier than Windows Server 2008 R2, turn on the virtual machine and then shut it down, to trigger the merge process at the new storage location.

   4. If you want to move the virtual machine back to the original location, free up additional space. Then, import the virtual machine back to the original location.

For more information about exporting and importing virtual machines using Hyper-V in Windows Server 2008 R2, see the blog post Hyper-V R2 Import/Export – Part 1 – The Case for New Import/Export Functionality (http://go.microsoft.com/fwlink/?LinkId=207802). For more information about exporting and importing virtual machines using the release version of Hyper-V for Windows Server 2008, see Hyper-V - Export & Import (Part 1) (http://go.microsoft.com/fwlink/?LinkId=207800).

For me it is enough to:
- delete snapshots
- shut down virtual machine
- wait few minutes and looking to Hyper-V console to see if it is still merging disks.

Are your virtual machines shutted down or slleping, or hibernated?
