Hi Experts

I would be extremely grateful if somebody could assist us with a current SBS VM server that is down..
Our Hyper Host machine is now low on disk space where the SBS 2011 Guest OS is loaded...
We have mistakenly shut it down to try to perform a merge to free disk space but this has just added to our problems..., as we do not have the necessary disk space to perform the merge , which consquently keeps restarting...
We have the current "files" in our VM folder
SBS 2011Server.vhd      16.03.2012        21:47 with a size of 181,153,654
SBS 2011 Server.avhd   16.03.2012       12:15 with a size of 137,186,763
SBS 2011 Server.avhd   16.03.2012        20:28 with a size of 28,202,466
SBS 2011 Server.avhd   16.03.2012        21:47 with a size of 140,382,423

This is my d drive , I have 152GB available on c (os) partition and approx 500GB on a my E drive which is an external E drive....

I have read various articles on the web but if somebody could be a little more specific on this particular issue we would be externally grateful...

can we delete/move the oldest avhd or will this result in data loss ?

thanks expert, hoping you can help us in our hour of need

You should not try to move or delete AVHD files manually otherwise you will lose you virtual machine.

Do you have other virtual machines on the same server? If yes, you could export and remove them to free some space.

We dont have any other virtual machines on the same disk, as this is a raid 5 with 3 disks in it....

so really there is just the one vm on these disks

thanks

The (somewhat lengthy, due to copy time) solution is to move the VM to another drive (EVEN USB), and then get rid of them normally.

Am I able to just use the Hyper V manager to move the VM, includling snapshots and then boot the VM from there... then as you describe manually delete the files from my fixed drive ?.

Is moving a VM to another drive a fully safe procedure ?
many thanks
