I keep getting messages about my docker img being full / high utilization, then it "returns to normal levels". Is there a simple command to expand the docker img to make the messages stop popping up. IE resize2fs /mnt/docker/docker.img 40GB etc...

It sounds like nzbget (or similar) is downloading / unpacking to the docker.img instead of somewhere in appdata due to a misconfigured docker application.  You should fix that problem, rather than masking it by increasing the size of the image

You can simply increase the size in the docker settings and then stop/restart the dockers service to get unRAID to expand it for you.

 

probably of more concern is why you are getting this message in the first place!    It suggests you have a docker slightly misconfigured so that is writing data internally to the container rather than to a location external to the container.

If your docker image is larger than 20GB, you're doing something wrong. Mine is under 3GB after years of use. As others said, fix the problem, instead of adding more water to a pool with a leak.
