Nextcloud showing wrong size

I just booted up an Ubuntu VM with a 600GB zvol as a disk in FreeNAS. I installed nextcloud with snapd and everything works perfectly, but when connecting through webdav, Windows only shows that the drive is 110GB and it only has 13GB free. I even went as far as connecting a different folder inside the root directory as external storage, but it still said the same thing and I tried to move 30GB worth of data to the external folder but it was still rejected.
Why isn’t it detecting the 600GB? Why is it limited to such a small capacity? Is there a way to change the size of the database? Does it come at a default size?
I also made the max upload file and filesize to 50G so that’s not it.
