Hyper-v 2008 R2
I have a 2TB host in which I am running 2 VM's
Exchange was a 900gb Fixed disk VM
Terminal server 200gb Fixed.
I was working remotely on my iPhone on the Exchange server (I know, don't ask) when I think I accidentally hit the snapshot button inside of Hyperv Manager.
The user called and said the server stopped working and I quickly realized it unexpectedly rebooted and the Address Book service failed to start automatically. I was trying to navigate my way around on my phone and thats when I think I hit the snapshot button.
I didn't realize this until 2 days later when looking inside my VHDS folder that a new AVHD file was created that was 818gb and timestamped exactly when I was working on it remotely.
The original VHD file was dated 2 days earlier and 825gb
The snapshot is NOT showing up in Hyperv Manager at all so I'm not sure what the best next steps are.
I figured I would first take the VM offline and export it to a another location before doing anything to preserve the Exchange server. I am running a Barracuda so I'm not worried about losing any email as that will trap everything.
I noticed in the settings of Hyperv Manager for Exchange that it is using the AVHD file as the primary file.
Questions
1 - If I take it offline, shouldn't the 2 files merge without me doing anything else? I just wasn't sure since the Snapshot does not show up in SCVMM or Hyperv manager.
2 - I should be able to see this process in SCVMM?
3- How long will it take to merge 800gb? I've seen varying results depending on disk speed, etc.
With an exchange server, this obviously needs to be done delicately without data loss. I assume my statement about the original Exporting of the VM will cover my bases for that?
Thoughts on how to proceed?
Thanks!
