I virtualized a physical box some time ago and it has been running fine on Hyper-V 2012. I could create, delete and merge snapshots and the avhd files would disappear. Now I notice that I have no snapshot listed in settings for this server but there is one on the Hyper-V host and according to settings for this guest, it is now attached to the avhd as the data drive and the regular vhd is not listed in settings, tho it is still on the host where it belongs.
The avhd has the GUID name appended to what the vhd was named and is only one-third the size of the vhd. The server is running fine and there are no issues for the users.
How do I get rid of the avhd file and get the vhd back as the primary, and only, drive?
