When you are using vmware to create Ubuntu Server VM, it will only use half of the assigned hard drive storage if you are not changing it in the installation process. Here is how to resize it.

root@util:~# vgdisplay
<snip>
root@util:~# lvextend -l +100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv
<snip>
root@util:~# resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv
<snip>

This method still works in Ubuntu 24.04 as of today (2024-07-04)
