SOLVED: Jellyfin finding music from unknown folders

[seasonedwok]

Hello

My issue is that Jellyfin is finding music from folders that I cannot see which I presume don't exist or I just don't have the knowhow to access. The pseudo folder music is not playable.

I am running on TrueNas Core with Jellyfin 10.8.10
I have a mount point configured in TrueNas from /mnt/pool1/plexmedia to /mnt/pool1/iocage/jails/jelly/root/media (using plexmedia folder for ease of access, Plex does not have access to my newly made "Muusika" folder)

Folder structure is /plexmedia/Muusika/A/MyAlbum
From Jellyfin music tab filtering by album I can see 3 copies of my album only 1 of which is actually playable and with a legible album cover. The 2 albums which are unplayable have the album cover image with a really big blur. Unplayable meaning I get a Playback error "This client isn't compatible with the media and the server isn't sending a compatible media format."

The album which I can find from my Windows file explorer and MacOS finder shows the location in Jellyfin as /media/Music/A/MyAlbum
The albums which I cannot play I also cannot find from both computers with "Show Hidden Folders" feature as checked. The folders "Music" and "_A" (notice the underscore) do not exist as far as I can tell.

/media/Muusika/Music/MyAlbum
/media/Muusika/_A/MyAlbum

As my experience with which I presume is a Linux based issue is slim to none, I have no idea how to troubleshoot this. This is also not an issue with just one specific album, it's with many others.

I have a very unfortunate solution to this issue - do nothing. I touched and did nothing to my server and Jellyfin for a day and came home to my issue fixed. Glad it's fine now but would really want to know what and why it happened in the first place.

Unfortunately, not a lot of people here (or anywhere) runs Jellyfin on TrueNAS Core. Scale, definitely, but not Core. So the peculiarities of Core, which is FreeBSD and not Linux, are not well documented.

Check your logs from yesterday for hints about any issues that might have been occurring and feel free to share that log here.

This sounds like a file had moved but a scan had not ran to update the location
