SOLVED: Fails to Start

[MrXirtam]

[*]Jellyfin Version: 10.9.6
Installed via: Debian Respository
Brief Description: Ran out of space on my hard drive due to an unrelated rysnc issue. Cleared the space, and now Jellyfin service fails to start back up.
Full explanation: I pulled up my Jellyfin on my desktop PC. It launched and I loaded into a media file. It played for a few minutes, then froze. I logged onto the server and realize the service was in a failed state. Closer examination, I realized the space on my root drive was completely full. Turns out an rsync error on my part filled it all up. I cleared up the space, and I now have at least 176 GB of free space. But upon trying to restart/start the jellyfin service, it starts, but then reverts to the failed state after 5-10 seconds. Checking the logs, I see this error listed after each restart:

I'm not sure what root element is missing or how it can be recreated. I'm thinking it has something to do with a Migrations XML file, but doing a find command for it returns nothing:

Code:

sudo find /var/lib/jellyfin -name "MigrationOptions.xml"

Any ideas on how I can fix this?

migrations.xml is in /etc/jellyfin. Try removing it if it is null.

[MrXirtam]

Wow, easy fix, this did it. The migrations.xml was in there and it was 0 in size. I removed it, and the service starts and runs normally.

Thanks so much!
