Need some help cleaning up a mess

[Embowe]

I've had a very simple unraid box up and running since 2019 with only a few dockers for pihole, Plex and torrents here and there. With the mistakes made while setting everything up and messing around my system isn't as "clean" as it should be.

Ideally I would like to start new and have to set everything up from scratch, but NOT lose my data. 
VERY basic knowledge with linux/terminal but if I can "fix" all the issues I have without having to do it all over, I'd be willing to but need samn "newb level guidence" 
I've run the "cleanup appdata" plugin and if I check docker names that I no longer have installed, they won't delete (permissions error?)
Unable to write to cache (it isn't full)

Basically, what do I need to do guys and gals to get back running

Reviewed the diags. Nothing stands out as being wrong.

 

I would do the following:

• Manually, review the docker containers you have as well as their "appdata" or "config" directories.
• Review where that is on your cache drive (likely) and remove things from that directory that no longer align with containers your running.
  • I have this issue after trying and testing tons of containers from the CA.
  • `mc` can be your friend to quickly navigate **hint hint.
• Run 'du' on your cache drive to see what folders are holding the massive amounts of data.
  • /mnt/cache# du -h * --summarize
• Lastly, run newperms (which looks like you ran recently after looking at the logs) on your cache drive to reset permissions.
