Cannot extend virtual disk in storage space with free space

storage-spaceswindows-server-2012-r2

On my Windows Server 2012 R2 I have a storage pool capacity of 2.22TB and 516GB free space, however I cannot extend my virtual disk past 1.72TB. The UI will let me create another virtual disk with the 512GB capacity but not extend into it.

On my other box I can get full capacity allocated.

How do I get it to let me extend my virtual disk into that free space?

Best Answer

Managed to sort my problem out by recreating the storage pool with just 1 disk, creating the virtual disk with 1 column and then adding the second disk and expanding. Would have been nice for a less destructive route but it did fix the problem, full capacity used now.

Hope this helps someone else in the future.
