I have an Exchange 2010 server running as a guest on a hyper V virtual host.
I see the .vhd for this server is 296,384.120kb on the HyperV host. This doesn't seem to change, including when I recently deleted 35GB of files from the Guest Exchange vm and the file size changed to 296,367,740 after a reboot...
On the Guest Exchaneg server itself, the "C" drive (only drive on the sys) is set to 499GB, with 78.6GB used.
I believe my Hyper V is a fixed disk setup within Hyper V (but not 100% sure...). Perhaps its as simple as I somehow told this file to be 300GB? I'm not sure how to confirm this?
There was some snapshots for this server, which I deleted from Hyper V manager, and let the server merge them on my next shutdown. This was successful.
In addition, I saw within Hyper V manager an option to "edit" disk where you select a .vhd and there is an option to "compact" it...but I have to say this option has a "scary" sound to it...
Is the "compact" option mentioned above feasible / worthwhile...or risky...?
Any ideas as to why this .VHD is so large, and what can be done to get it to more "reasonable" size considering the data is less than 100GB right now? I have confirmed there are no more snapshots in place, restarted the guest and the whole Hyper V host.
