How to resize / make use of full disk

I deployed ZimaOS Beta 1.1.0 to my SSD and after booting, I was surprised that it does not use the full drive.

Shouldn’t it expand the filesystem automatically to make use of the complete disk?

I can resize like this under pve, and zimaos1.1.0 should be about 12G in size, what kind of VM do you have, or provide your installation?

resize /dev/sda8

Oh, I installed it on bare metal (x86) and the screenshot was from gparted in Ubuntu Live.

Can you just resize /dev/sda8?
