virtual machines - Allocated too much memory from VMware to windows MBR disk, how to remove

I'm a junior sysadmin and today, I have allocated too much memory to a disk on a windows server 2008 VM through vsphere.



In my srv2008 vm, I saw two disks of 2tb with the same letter (spanned layout)
I needed space so I went in vsphere and raised capacity for one of the two drives, without noticing that in windows, they were mbr.



Now, all the disk that are part of the spanned layout are "Healthy(at risk)", I assume because on one of them I went over 2TB limit for mbr.
It seems like I can't easily remove the memory I allocated on vsphere, and I can't make another disk and add memory to it to increase my disk D:/ space.
I'm running out of space very soon and I'm racing against the clock. This is the main file server, anyone has an idea what I could do?



I tought about just creating another disk, not part of that spanned layout however I don't have enough free space to transfer everything, and I assume a lot of stuff here have hard coded paths to some specific file and moving them else where would break everything




The storage is on a nimble storage array
