Last night I upgraded a server (Dell 2970) to have four 1TB Hard Drives in RAID 5 which leaves a 3TB block. I tried to partition this but keep getting an error that GPT is not supported so.
I found a site online telling me I need to run the dd command and right random data to /dev/sda. This is great (if it works) but taking forever. I have two more machines to upgrade today and not a chair in sight! Does anyone have advice on how I can avoid this issue beforehand?
Thank You for your advice and support.

Do you really need such a large partition? I would split it up into smaller chunks using LVM on top of the RAID array, to avoid using unsupported workarounds.
