So my unraid box has gone down a couple time due to power outages.  Once it went down for no reason I could tell.  Now my docker is acting up.  I can't add any containers now.  It won't let me select anything for the volume.  Scrub for the docker settings even gives me an error (ERROR: getting dev info for scrub failed: Inappropriate ioctl for device).

 

Is there a way to competely clear out docker and reinstall it?

You can easily delete the dockers and re-install. The install dropdown will show the saved installs as my-xxx at the start of the list. Just pick them and they will re-install what you had before.

I don't mean individual docker images and containers.  I mean docker as a whole.

The same idea applies.  Delete the docker image, recreate and add all the containers again using the my* templates

Thanks.  I wasn't able to find the image previously.  This time I was able to.
