Interesting little wrinkle setting up a RAID5 on 4x4Tb drives in a Dell PowerEdge R520 with a PERC H710 mini controller. Using the fancy integrated interface (F11) the first VD of 20 Gb is fine, but the second only allows just under 1Tb to be used!
Using the basic bios extension thingy (Ctrl-R) it works fine. Also, somewhat faster…
