Guys I could use a little help.
Last year I upgraded one of my hyper-v servers to 2012 and enabled storage spaces on it. The server had a Dell Perc H700 with 6x 3TB in Raid6. I added 1 extra drive and selected Online Capacity Expansion from within the Raid controller software. So now the raid array has increased in size from 11TB to 14TB.
Now the question is as follows :
How do I increase the size of the storage pool/physical disk to make use of the now unused space ?
I've added 2 screenshots of my config to explain further :
