Recently, as far as I could tell, Docker crashed on my unraid setup. jellyfin and jellyseer had stopped working so I logged into the webgui to check on things only to find an error message saying docker failed to start.
Unfortunately, being more familiar with less commercial software, first thing I tried was a restart, which fixed nothing. After some cursory google searching and trying a few things from here, I finally tried backing up and then deleting the docker.img file and allowing unraid to make a new one upon rebooting.
This finally got it restarted but obviously cleared out all of my configurations, which I thought I could restore using the "appdata backup" plugin but that didn't seem to work.
So my question is What caused this and if at all possible what can be done to prevent it in the future or make recovery easier before I go in and set everything up again?
