Restored 2012 OS onto larger volume, can not use extra space

I just restored my Server 2012 install from a 1TB volume to a 2TB volume. I wanted more storage and it was a better RAID controller. Trouble is, while the partitions are still all the same size and add up to (roughly) 1TB, the OS is somehow showing that I am using all of the 1.8TB of the new volume and won't let me expand any disks to take advantage of the new space. I don't know what went wrong. I was going to try to boot from another disk and try to examine the disks more closely, but I was hoping that I am simply missing something obvious.

Look at the attached image to see what I mean. The volumes all add up to about 900GB (the blacked out one is a USB-based backup volume), but the OS still thinks that all 1.8TB are being utilized. Little help?

Without knowing about the disks or pools defined, it is tough to say where the remaining space is hiding. Not enough info in that screenshot.
to me it looks ok; it has assigne dthe whole 2TB drive to your OS
is that not what you wanted?  how much free space does it show?
it seems the virtual disk configuration issue

See attached disk management. As you can see, the disks themselves do not add up to 1.82TB

Press on Tools - Computer Management - Disk Management. Can you give us the screen shot from that snap-in exactly? Like on my example.

Nobus,  on the screen shot you can see the answer to your question. The space is not allocated.
I use Parted Magic all the time for this sort of thing. I just didn't want to use it if something was wrong with the partitions.

Thanks!
You are welcome!
Take care
