Jellyfin won't start: SQLiteException disk I/O error

[cryotek7]

Hi everyone,
Ran into an issue with my Jellyfin install. Runs on an LXC container on Proxmox, Jellyfin installed on one ZFS pool, media on another ZFS pool. Restarting the container does not fix issue. There are no issues with hard drive health or disk space. From searching online I read that this error can be caused by many different problems (some mentioned in this bug thread), and have been going around in circles. Any help appreciated.

Make sure that the permissions on the directory containing your database hasn't changed. This is usually caused by jellyfin not being able to read AND write the file.

Or possibly that the disk is full.
