I am attempting to run a job in my jellyfin container to generate intro-skipper media segments. This job involves writing media segment files to disk. The job failed overnight, and now fails immediate upon running, with error “No space left on device” in the logs.
The SSD of the host machine has 1TB of available space.
The /home/umbrel/umbrel/app-data/jellyfin/data is suspiciously exactly 25GB.
Is there some process by which umbrel limits the size of the app-data directory? The jellyfin container has a much larger volume than 25GB in the /home/umbrel/umbrel/data/storage/downloads/ volume, so I assume it’s not a docker problem or jellyfin problem.
I believe it’s because I need to enable the “large directory” feature on the filesystem. This requires unmounting the filesystem and running e2fsck with the -O large_dir option. However, this might be challenging since it’s the root filesystem. I think it should be enabled for umbrel os, maybe this can be classified as a bug
