Can't install to hard disk - too many sectors error?

Hi,

<Ware! Linux newbie:/>
I have followed the instructions for installing RancherOS using a cloud-config.yml file but I am getting an error saying the 4TB hard disk I wish to install on has too many sectors for an MS-DOS partition table. The disk has had another Linux installation in the past so I just want to install onto the /dev/sda root and wipe it all. Anyone know how to force RancherOS to do this on a fresh install ?

Thanks,

Boo

Obviously the problem is related to the fact that you’re trying to install a large partition (4TB) on a MBR partition scheme. You’re supposed to be using GPT (normally associated with UEFI). Of course the Rancher documentation doesn’t explain this.
