Here is the short version of what happened.
I setup docker to use the default directory /var/lib/docker. It has been running great for months. This past week I noticed serval failures on my docker images. After looking into it, I realized my main partition is full. The main partition is btrfs and attached HDD is xfs. The first thing I did was copy the docker folder to my attached HDD. I then tried a symlink for /var/lib/docker but it didn't work (my guess is it due to the different filesystems). I then went into OMV and created a sharedfolder to the new docker path on the attached HDD. After that was done, I configured docker to use this new folder and then fired it up. It started successfully. After I confirmed it was working, I turned the service off and then copied the contents from the backed up docker folder.
The issue I have now is that docker will not start when I use the backed up docker folder. It only works when I point it to a blank docker folder.
I really do not want to have to re-setup all my docker images again. Any idea on what I can do to save it?
I had Radarr, Sonarr, Lidarr, Transmission, SabNZBD, Tautulli, etc.. As a worse case, is there an easy way to import settings and status to configure them again.
Note: I noticed the copied docker folder is much larger than the original folder.
