All *arr apps should use root folders to organize media. If I understand the question, here’s the hypothetical situation:

1. Create a root folder for *Arr App.
2. Download media until drive is full.
3. Create a new root folder that points to different drive.
4. Configure *Arr App to move new downloads to new root folder created in step 3.

You should be able to have multiple root folders, but I’ve only checked in So are. One problem you’ll run into is that you can’t break up music artists or TV show series across root folders.

You might want to consider something like OpenMediaVault or Unraid to manage your storage. Either platform (or others) allow you to add drives as needed. I don’t use either so I’m just passing that along as a consideration.

Not sure if my setup is unique or wrong but here’s what I use:

1. I registered a domain with Name cheap and created subdomains for the tools I wanted to access (i.e. jellyfin.domain.tld, sonarr.domain.tld)
2. A DDNS client on my OpenWRT router updates the IP address for those subdomains. Traffic for each subdomain is pointed at my server.
3. Nginx Reverse Proxy runs on my server. This provides HTTPS certificates and is pretty straightforward.

I also use Tailscale for remote access and I’m not sure that my friends and family are ready for that. (Admittedly, I’m still on Plex.) Registering your own domain and using a DDNS service and reverse proxy will give your users an easier experience than Tailscale. I can give an easy-to-remember URL to folks rather than a new VPN platform to learn.

If security is more important, Tailscale is the best option for remote connections.

Why don’t we need this for Plex? Because Plex has all of the above steps baked into its service.

Flauncher is a great pick too

I use the ONN 4K Pro and the ProjectIvy launcher. You can completely hide the standard Android TV OS launcher and its ads. Button Mapper is another good app to have on Android boxes. The remote is full of app-specific buttons that I’ve either disabled or remapped to alternative apps

I have no idea which codecs are supported.

Thanks everyone, I feel much better about moving forward. I’m leaning towards Proxmox at this point because I could still run Windows as a VM while playing around and setting up a new drive pool. I’d like a setup that I can gradually upgrade because I don’t often have a full day to dedicate to these matters.

MergerFS still seems like a good fit for my media pool, simply only to solve an issue where one media type is filling a whole drive as another sits at 50% capacity. I’ve lost this data before and it was easy to recover by way of my preferred backup method (private torrent tracker with paid freeleech). A parity drive with SnapRaid might be a nice stop gap. I don’t think I feel confident enough with ZFS to potentially sacrifice uptime.

My dockers and server databases, however, are on a separate SSD that could benefit from ZFS. These files are backed up regularly so I can recover easily and I’d like as many failsafes as possible to protect myself. Having my Radarr database was indispensable when I lost a media drive a few weeks ago.

Good catch, yes my drives are 12TB. My brain is still stuck in 2005. :)
