Disk usage overstated?

Installation

I am using dedicated HA OS installation. According to Home Assistant, I am using 22.6Gb of space:

If I check with du, I am only using 997 MB. Where is the other 21.6 GByte used? :sob:

You are only looking at the use inside the Home Assistant container. There are other containers. e.g. Supervisor and each add-on.

3

You are looking in the space used by the core container. To get the real spaced use, you have to check at the console, or ssh in the OS

5

They are from SSHing into the Home Assistant container. Not the host machine. There are other containers outside the HA container your commands can not see. You need to log in to the host to see everything.
