Root partition is four times larger than I specified while installing


I'm running Ubuntu Server 18.04, with 4x2TB disks in raid 0. In the web panel OS install page I specified 4 partitions, /boot 500MB, root 15GB, swap 4gb and /home with all the rest. However, if I'm reading this right, the root partition appears to be 60GB. I have no idea what I've done wrong. Any help would be greatly appreciated.

Code:

You marked you previous thread as "solved" without any explanation. You can't expect help if you don't give something back.

First guess would probably be "RAID0" - which was your deliberate choice.

Unfortunately, the problem is gone in my first post but there's no good answer. However, you're right, my apologies, I'll leave an explanation.

Could you please elaborate on why raid 0 would be causing this?
