SOLVED: Library scan not loading all available media

[schotlekoff]

Hello,

I was running out of space, so I decided to upgrade my storage. I changed my Seagate 8 TB external drive for Buffalo 2-bay enclosure with 2x6 TB HDDs installed. The enclosure is set to separate drives: one for movies and one for TV shows. After the upgrade, I deleted all old entries from the Jellyfin libraries, set the new source folders, and ran a fresh scan. Jellyfin found only about 1/5 of my media files. I ran a couple of more scans: same output, just some of the titles are different. I tried playing the files with VLC directly from the drive and there are no issues at all (both from a PC and a smart TV). On top of that, some of the movies are grouped in collections that they are not part of.

p.s. The server is running on Ubuntu Server 22.04.

What are the mount parameters for these external drives? And does the jellyfin user have sufficient permissions?

Drives are formated in exfat, I set up automount in fstab as:
# HDD"X"
UUID="XXXX-XXXX" /media/"XXXX" exfat defaults,auto,umask=0000,uid=100"X",gid=100"X",rw 0 0

Where uid and gid "X" are jellyfin user/group IDs.
Folder permissions for each drive are set to all read/write/execute (a+rwx) using:

sudo chmod -R 777 /media

Movies are organized in A-Z subdirectories and TV series in title/season.
There are cases that only 4 out of 20 episodes in a season(folder) are recognized, so I think this should not be permissions issue?!

Remove all the extra options for that mount. Should only need "defaults". Once you remount that volume, or reboot, make sure Jellyfin has permissions to the folder.

[schotlekoff]

I will try that. But this configuration is tested and proved working. My old external drive was configured the same way. As far as I remember, without the extra options I was getting read/write errors, because exfat do not support permissions like unix file systems.

Ooohhh. News to me (only used NTFS or EXT4). Then how does exfat do permissions? Because this sounds like a permissions issue.

exfat is basically 777 because it does not store permissions metadata, but you can force uid,gid from the mounting options https://manpages.ubuntu.com/manpages/tru...use.8.html

With mount options umask=0000 to force a+rwx permissions (777) and uid/gid to set ownership of files/directories to the jellyfin user. 

I still don't know what cause the issue, but I found the solution - reinstalling jellyfin after previously completely removing everything linked to it. Brute-force solution, but it get the job done!
