Is it normal for /var/lib and /var/log to each take over 5G space?

After running:

cd /var/discourse
git pull
./launcher rebuild app

ncdu returns:

Seems to me that the diff and log are taking too much space. Is that normal?

/var/lib/docker/aufs holds the disk of your docker image, so yes, that is normal, there is an entire linux there.

/var/log/nginx hold every request that hits your forum, so it will be bigger the more access you have. However it rotates for you.

That’s /var/log/nginx on the host (I presume), that isn’t a standard setup, so it’s outside the scope of what we can offer suggestions on.

We are mounting nginx log to /var/log now:

That’s /var/log in the guest, and it gets mounted to /var/discourse/shared/standalone/log/var-log in the host, so the Discourse nginx logs are part of the 3.4GiB shown for /var/discourse. Some other site is on the machine that’s generating so many logs.
