disk space creep?

[copykatze]

Hi, I installed workadventure by the help of this repo in April 21 - thanks a lot for sharing :)

Now I just saw that the smallest hetzner cloud server CX11 is running out of its 20GB disk space.

I found that journal took around 2GB, so I did

$ sudo journalctl --vacuum-size=100M

and now it runs at 90% space used:

$ df -h Dateisystem Größe Benutzt Verf. Verw% Eingehängt auf udev 949M 0 949M 0% /dev tmpfs 194M 820K 193M 1% /run /dev/sda1 19G 16G 1,9G 90% / tmpfs 968M 0 968M 0% /dev/shm tmpfs 5,0M 0 5,0M 0% /run/lock tmpfs 4,0M 0 4,0M 0% /sys/fs/cgroup /dev/sda15 121M 138K 120M 1% /boot/efi

But I would expect it to fill up again soon, so if anyone has any suggestion how to find out what is causing this and how to control the creep, I would appreciate any hints :)

Cheers!
