Dunno what happened today, but it seems I received an update that filled up the docker usage to 100% (solid red all the way up) on the Dashboard page and rendered my server unusable. Even a reboot did not allow the Docker to start

I know there was an update sent without my knowledge and consent because the /etc/sysctl.conf file changed (what else was changed??)

 

UnRaid is at version 6.12.11 and was working fine before this "sneaky" update and is working fine now after I had to manually increase the /mnt/user/system/docker/docker.img from 30 to 50GB. Now, that same docker.img is over 80% unused and wasting valuable disk space

If I sound not-too-happy, it's because I am

That usually suggests an issue with incorrect docker mappings, please post the diagnostics.

What do you think was updated as Unraid does not do updates unless you ask for them!  Do you have auto-updates of plugins or docker containers set?

 

Your description sounds like a docker container auto-updated itself (which Unraid has no control of) and this is the underlying issue.

here's my sysctl.conf file. I cannot tell exactly what changed. But, the "vm.swappiness=1" was removed and I had to reenter it after the reboot

I'm not aware of any auto-update plugins or anything. I manually check for updates of plugins and dockers about once a week or so.
But, didnt get any updates for the last few weeks

My server was up and running fine without any glitches for almost one year

Unraid runs from RAM, that will always go back to stock after a reboot.
