So there’s this annoying thing Ubuntu Server does by default, which is not use the whole drive. This is a waste of space and i’m gonna show you how to fix it with a few commands.
$ sudo lvm lvm> lvextend -l 100%FREE /dev/ubuntu-vg/ubuntu-lv lvm> exit $ sudo resize2fs /dev/ubuntu-vg/ubuntu-lv
And that’s it. You should now see the whole drive used with df -h command
