I've just got a couple of 2010 Dell servers. One of them has 4x 1TB disks. I configured them in the RAID controller to use all of them in RAID5 to give me 3TB of storage + 1TB for parity. There are no other HDDs in the server. I wanted to just have one 3TB VD, and have Windows Server 2016 installed on it, too.
When I go to install Server 2016, it correctly shows me a single disk, 2.7TB in size; but when I click New, it gives me a 2048GB partition, plus 746GB of unallocated space. Trying to click New on the unallocated space results in a error code, that returns 0 results on Google.
From searching the internet, I've found that it's because MBR does not support disks >2TB — the disk instead needs to use GPT... but by the looks of it, you can only use GPT on a non-boot disk. So if I'm booting Windows Server from it, I can't use GPT.
Is that correct? So am I stuck with having 1x 1TB HDD for the OS, using MBR; and 3x 1TB HDD's to use in a 2TB+1TB RAID5 configuration? Leaving me with only 2TB usable on my main VD?
