Add external drive to homeassistant supervised (in docker)

Hi all!

This is my first post, but absolutely not the first time on this community.

I’ll briefly explain my hardware setup, and continue with the question
I’m running homeassitant supervised in docker on Debian 5.10.162-1, on a NUC 10i3FNK

I am using for a while now, but my SSD is slowly but surely filling up. Now I’ve added an external SSD (/dev/sdb) for motionEye addin to store recordings instead.

But now I can’t seem to add this volume to docker.

What I’ve tried:

  • Mount it directly in container “homeassistent” with docker exec but then I was unable to reach from the front-end (using the terminal or add-ins)
  • Through the hassio-superviser container by mounting it in the data folder as it is noted in /etc/hassio.json, but it gave the same result; I was able to see the folder, but when opening it in the frontend there was nothing (while on the NUC directly it did work)

Am I missing something here?

Thanks in advance!
