Recently I got warnings from my HomeAssistant Server that the filesystem is getting full:
It took me some time to figure out, how to clean that up.
When I opened the WEB SSH Terminal from the GUI and checked the usage it looked like this:
[core-ssh /]$ df -h

When I looked into the mounted filesystems I could not find anything that caused the issue. But with the SSH extension of HomeAssistant, you do not have access to the root filesystem of the HomeAssistant Server. Read this Article to get access to the root file system.
After some searching around I figured out, that I had some unused docker images on the server which consumed a lot of space. Here are the running containers:
# docker ps
