Hey all, seeking some help here with what started as one little issue but quickly spiraled into something much worse. The trace logs don't seem to be telling me much, because there aren't errors being thrown. I built up a very full arr stack + monitoring over the years and watchtower keeps everything updated, so there were updates around the time of these issues, but I am not sure if that is the cause. The stack is 'Plex Media Server' running as a standalone app, everything else is in docker.
Long and short of it:
- Little Issue: I noticed about a week ago that some downloads were not importing automatically, and after looking into this today it seemed like both Sonarr and Radarr were having trouble with downloads that were packaged in any folder containing at least one "." in the folder name (like
Movie.1080p.5.1ch > movie.mkv). Automatic import would fail because both Sonarr and Radarr seem to not understand the folder attribute anymore, and would say "unsupported extension: '.1ch'" and therefore not see the file because it's viewing the folder itself as a file. Okay, not ideal but maybe it's just a specific version issue and I can manually import for now. - Much, Much Worse: As I was finally working on this issue, I realized that during a similar period, everything being imported by Sonarr and Radarr (both manual and auto) are seemingly grabbing random files from my library folder(s) as the source for the final import?? For example I had a user request a movie "The House" (2007) on overseer a few days ago.
- QB downloads this file to a 1TB flash drive (to save my HDD from wear). No issue.
- Radarr failed to automatically import it because the folder name had "." in it and sees that as a (unsupported) file itself
- I do a manual import and radarr shows me the correct path on the flash drive for the movie file (I later checked the file and confirmed it's the correct movie on the flash drive). I click import, Radarr is supposed to copy this file and put it on my HDD with the correct naming and folder structure.
- The file that Radarr ended up copying to the HDD /Movies/ (plex library) folder is a 35m episode of John Oliver from June 2019, which only exists in a HDD library folder that Radarr does not have access to (only Sonarr). It named this file with the original name and extension of The House's .mkv file.
How tf does that happen? Is my 3 year old HDD nearly spent and about to call it quits? Why do these issues exist in both Sonarr and Radarr and seem to have popped up at the same exact time? This is now happening with every single thing I download in Sonarr or Radarr, both manual and automatically.
I don't see how it can be Radarr because Radarr doesn't have my /TV Shows/ folder as a bind mount, but that is where it must have got the file it copied into /Movies/The House (2007)/ because that file does not exist on my machine in any other location ... I'm normally pretty good with this stuff but this one has be dumbfounded and unsure where to even start troubleshooting. I've stopped their containers for now and I'm considering just burning it all down and starting fresh with those docker services before my libraries get wrecked further as I tinker aimlessly. I sincerely thank you, for reading and for any help you can offer. I put a lot of time into this little tech stack, and this is the first time I'm at a loss for even a concept of a solution to an issue.
TL;DR: sonarr and radarr have gone rogue and are preforming cp commands that are copying incorrect files they should not even have access to.
