Jellyfin on synology doesn't launch - pierrot277 - 2025-11-04

Hi everybody,

Since the release of the 10.11 version, Jellyfin doesn't want to launch anymore on my synology DS124. 
Here is the log of the app.
Maybe someone know how to resolve the problem. Thanks in advance!

Hello Yurk,

Thanks for your response. Yes i saw that but i have 3.1 TB available. So i doesn't understant why the path /tmp/jellyfin have only 456Mb. Maybe somebody know how to give more space to this folder on a Synology NAS?
Thanks

Your 3.1 TB are in /volume1. The folder /tmp is not part of it, it's part of Synology OS called DSM any typically a temporary file system using the RAM of your DSM.
