I have a 2K8 Server as a Guest, and it's complaining that it's out of disk space. It's currently at 20 gigs, so I powered down the guest, fired up the VSphere 4.0 client and went to edit the vm properties. I increased the Hard Disk 1 to a Provisioned Space of 40 gigs. When I fired up the Guest, it still says 20 gigs, and almost out of space, though the Provisioned Space says 42 gigs and the used says 40 gigs.
What can I do?
