Additional Information (if applicable)

  • Software title | Jellyfin

Following a recent dietpi-upgrade. I noticed I lost access to my Jellyfin server.
Upon searching into journalctl logs I found the following lines:



juin 14 21:09:10 DietPi jellyfin[643541]: System.InvalidOperationException: The path /mnt/dietpi_userdata/jellyfin/data has insufficient free space. Available: 936.4MiB, Required: 2GiB.
...
juin 14 21:09:10 DietPi jellyfin[643541]: Unhandled exception. 
...
juin 14 21:09:10 DietPi systemd[1]: jellyfin.service: Main process exited, code=killed, status=6/ABRT
juin 14 21:09:10 DietPi systemd[1]: jellyfin.service: Failed with result ‘signal’.

I had this problem in the past but it has been solved by some action following a post here (or was it a fix to the package? I cannot remember).
Can I do anything? I don’t have 2GiB available (and neither do I plan to dedicate such space to logging).
Thanks in advance to anyone answering.

The topic you refering to was about the /tmp file system where jellyfin required quite some space. The path `/tmp/jellyfin` has insufficient free space. Required: at least 2GB. · Issue #15036 · jellyfin/jellyfin · GitHub

We did a workaround on low memory systems to have log files located on /mnt/dietpi_userdata/jellyfin/log dietpi-software: Jellyfin: fix install due v10.11 changes · MichaIng/DietPi@ce6a02f · GitHub

However your issue has a different message

It’s /mnt/dietpi_userdata/jellyfin/data and not the log or cache directory. It’s the data directory. Therefore you would need to check your disk space. It has nothing to do with memory.

Thanks for helping @Joulinar . Here you go

What’s “worrying” me is that part of the message: Available: 936.4MiB, Required: 2GiB.
I don’t want to dedicate 2GiB to logs.

Your SD card ist filling up slowly

You could move your dietpi user data directory to your external hdd as this one has plenty of space. Our drive manager has an option for this

As an alternative you would need to check the content of your SD card for the directory containing the majority of data.
