Nextcloud disk not full size

I have got Nextcloud inside a VM with a 201GB disk. But Nextcloud only sees 99GB. How can I resize/format the other space? It`s showing up correctly under /dev/sda3 but not at the ubuntu–vg** part.


Nextcloud 18.0.2
Ubuntu Server 20.04
nginx 1.17.10


Checkout one of the many tutorials on LVMs:

I’m new to linux so I didn’t know what to do here. Thanks!
