Trying to install Discourse in an Ubuntu VM on Proxmox

@schleifer Thank you for answering!

How do I go about using lveresize? I’m not familiar with resizing partitions.

Looking at some other code examples online, I assume something like this?
lvresize -r +99G /dev/mapper/ubuntu--vg-ubuntu--lv

Does lvesize know to take the 99 GB in /dev/sda3? More clarity would be helpful.
