Movies hang (I/O error)

[galapia]

Hello,

I have a problem with my Jellyfin server (10.10.3, on Debian. NUC based on Intel N100 processor). All my movies are stored in a external USB NVMe, formated in ext4. My Jellyin is installed in a docker.

In the Jellyfin app on AppleTV, sometime a movie hangs. In logs, I have the following error:

[2025-01-02 12:58:41.529 +01:00] [ERR] [42] Jellyfin.Api.Middleware.ExceptionMiddleware: Error processing request: "Input/output error : '/media/Movies/xxxx.mkv'". URL "GET" "/Videos/e206384774c97cd13b2d409d661bccce/stream".

My movies folder is shared via SAMBA, so I can access it on Windows. If I try to play the same movie directly on Windows, it crashes exactly at the same timeframe than in Jellyfin. If I reboot the server, everything works fine.

I don't think it's a hardware USB problem. The device is almost new and, as I said, if I reboot, I'm able to read the movie... until the next crash in another movie. Strangely, it seems I have this problem only with AppleTV Jellyfin app.

As I also cannot read the movie in Windows, I don't think it's a problem with transcoding.

Thank you in advance for your help

Can you share your entire jellyfin log via pastebin?

Hello TheDreadPirate. Sure, you can find it here : https://pastebin.com/0JAtGKPN

I hope this help

[TheDreadPirate]

When this happens, are you able to access the hard drive from the command line and see its contents? IMO, this sounds like the hard drive is going to sleep or something.

[galapia]

As I can access the drive through SAMBA on Windows and read other movies, yes, the drive is not sleeping. As I said, if I try to read, on Windows, with VLC Media Player, the movie who crashed on Jellyfin, it will crash exactly at the same timeframe.

The only way to fix the problem is to reboot the Linux server

Is Jellyfin running off the same storage as the media? Can you share your docker compose?

[galapia]

Jellyfin is installed in the internal NVMe of the NUC. Media are installed in the external NVMe drive, on USB.

The compose file:
version: "2.1"
services:
jellyfin:
image: lscr.io/linuxserver/jellyfin:latest
container_name: jellyfin
environment:
- PUID=0
- PGID=0
- TZ=Europe/Berlin
- VERSION=docker
volumes:
- /home/galapia/jellyfinDocker/configconfig
- /home/galapia/jellyfinDocker/cachecache
- /media/externalDrivemedia
devices:
- /dev/dridev/dri
restart: unless-stopped
network_mode: host

[TheDreadPirate]

I'm assuming you mean the entire server, not just the jellyfin container. How much free space do you have on the root volume?

What mount parameters did you use in /etc/fstab for this drive?

And can you look in the system log for anything that stands out? It might be easier to wait until this happens again. /var/log/syslog.

Hello,

Sorry for this silence. I didn't change anything and the server is working fine now. No idea why.

I will contact you again here if I have this problem again.

Thank you for your help !

Hello... again !

2 days after my previous message, I had the problem again. I had a look in Linux logs and found the following errors:

This time, I was unable to read any movie in the disk. I needed to reboot the computer.

SMART data of the disk are ok, I don't think it's a physical problem. I looks like Linux is reseting the external disk (4th line in the log)

Any idea?!
