Jellyfin Web Configuration on Truenas Scale

[Efficient_Good_5784]

A lot of people struggle with permissions on Truenas.

I would:

1. Make a new dataset
   
2. Use the Truenas GUI to apply permissions to it so that it's owned by the Jellyfin app user
   
3. Edit the Jellyfin app to host mount the new dataset as: /jellyfin/jellyfin-web
   
4. Run the app as @TheDreadPirate states to auto-populate the new dataset with the files
   
5. Turn off the app, then go edit or replace the file you need in the new dataset
   
6. Reapply the permissions on the dataset just in case you copied a file not owned by the Jellyfin user
   

Once you do that, you should be able to restart Jellyfin and see your changes.

And just so you know, you can use vim in Scale's system shell to edit files.
