None of those messages appear in your diagnostics, and they only show 8% docker.img used. Where are you seeing those?

They appear in my notification popups when I log in and they are archived under tools>archived notifications. I get them constantly but I just double checked my plex logs and the errors do not line up with plex streaming so I am at a loss.

So after some more forum reads I have maybe come across something similar. I may have originally had some of my dockers set to run off the aray and when I moved them to "Prefer: cache" I did not stop the dockers before doing it. I have stopped all my dockers and VMs and I am running the mover now to make sure everything is in the correct location.

It is only an issue with 6.10.0RC2 AFAIK and you are running 6.9.2.

So, probably not that.

 

This is probably a docker container writing stuff to a path that is not mapped to a correct share, thus writes in the docker image.

Could be Plex transcoding stuff, could be a downloading App, etc.

 

You should check that your Docker volume mappings are all correct. Remember that linux is case sensitive.

Well I know it is not plex because I looked at the plex logs and there was nobody streaming from the plex server during the last time this happened. The only other 2 things I have running is crashplan which is only backing up my data to the cloud and pihole on a VM. I managed to kill pihole yesterday so I have disabled that VM for now so that only leaves crashplan and plex running. I will see if I can figure this out.
