I’m just getting started on my first setup. I’ve got radarr, sonarr, prowlarr, jellyfin, etc running in docker and reading/writing their configs to a 4TB external drive.

I followed a guide to ensure that hardlinks would be used to save disk space.

But what happens when the current drive fills up? What is the process to scale and add more storage?

My current thought process is:

1. Mount a new drive
2. Recreate the data folder structure on the new drive
3. Add the path to the new drive to the jellyfin container
4. Update existing collections to look at the new location too
5. Switch (not add) the volume for the *arrs data folder to the new drive

Would that work? It would mean the *arrs no longer have access to the actual downloaded files. But does that matter?

Is there an easier, better way? Some way to abstract away the fact that there will eventually be multiple drives? So I could just add on a new drive and have the setup recognize there is more space for storage without messing with volumes or app configs?
