Thank you for that. That makes sense that a Docker container could have created that without my knowledge. I'll have to dig deeper into the Dockers I have installed.
I know this is an old post, but I just noticed the creation of the same share "unRaidLars". You had mentioned you solved it, but I did not see an explanation of what it was or where it came from. Google is not being helpful on this. Could you elaborate on your findings, specifically, how did the share get created and what is it for?
