How to specify where everything is stored on Ubuntu Server 18.04?

Heya!

I know this is a newbie question but I want to know how to specify where all the files are being stored. I installed Seafile Pro 7.0.13 on Ubuntu server 18.04 with a docker and I thought if I change the volume directory of MySQL, Seafile and Elasticsearch data that all data would be stored where I specified but after uploading some files to the server there is nothing in these directories. Here is how I have it set up:

docker-compose.yml

So for example here is a volume for MySQL:

 volumes:
   - /home/jan/seafile/MySQL # Requested, specifies the path to MySQL data persistent store.

Im really new to this so any help would be appreciated :slight_smile:
