OpenMediaVault VS Guides

You might want to consider the previously mentioned MergerFS and SnapRAID, or MDADM and LVM for your setup. OpenMediaVault [https://www.openmediavault.org/ is a solid choice in this regard. Additionally, if you're planning to run something like Proxmox, you could look into deploying Starwind CVM on top of it. Pretty much like in this guide: https://www.starwindsoftware.com/resource-library/starwind-virtual-san-vsan-configuration-guide-for-proxmox-vsan-deployed-as-a-controller-virtual-machine-cvm/ .

You would better to install OMV instead. It's a ready to use fileserver solution with web interface.

So I'm working on a similar setup with an ancient desktop my in-laws were getting rid of. I installed OpenMediaVault directly to the hard drive (it's so old that I assume it wouldn't work too well as a hypervisor), with a 4TB external HDD attached. OMV supports Docker by means of a plug-in and I'm running a Jellyfin container with no issues at all. I'm still manually downloading everything to the HDD but *arr containers are my next step, as well as setting up a gluetun container to route all that through a VPN.

That is possible (it's automated to a certain extent). It also depends on the NAS OS. Unraid, for example, can work with drives of different sizes while using the largest one for parity. TrueNAS uses ZFS so you won't be able to just add a drive to your RAIDZ and expand it. There's also openmediavault: https://www.openmediavault.org/ that uses Linux Software RAID and you can add a new drive there but you can't combine drives of different sizes. And there's also Starwinds NAS that supports both Linux Software RAID and ZFS: https://www.starwindsoftware.com/san-and-nas. Plus, I would avoid SMR drives in RAID: https://nascompares.com/answer/list-of-wd-cmr-and-smr-hard-drives-hdd/

I'd put it like that: if you have a spare PC, then it's definitely worth trying. I would also look into openmediavault (minimal RAM needs): https://www.openmediavault.org/ and Starwinds NAS (supports both ZFS and Linux software RAID): https://www.starwindsoftware.com/san-and-nas

You want usenet it’s a-lot better than torrents. Yarr https://trash-guides.info is how to set them up for max quality , Set up Radarr and http://Sonarr.tv For tv shows Set up Sonarr Look into how to use the Usenet it’s so better then torrents but use torrents as a fallback. Get Emby media server or Jellyfin media server.

So for what it's worth, the easiest way to do all of this is using the Trash Guides: https://trash-guides.info/

As well as taking a look at trash guides: https://trash-guides.info/

One last thing I would recommend is going through proper folder structure for arr apps to work properly and for that thrash guide has excellent documentation and instructions on how to set it up.

Here’s some guides to help you: Trash Guides Wiki Servarr

Now going to the trash guides github (https://github.com/TRaSH-Guides/Guides/tree/master/docs/json/radarr/quality-size) we can see 3 matching json files, with min and max settings for all the qualities.

https://trash-guides.info/ can also be a good source for info about the whole thing.

You have 30 days trial with unraid so play with it. Watch spaceinvader one vidoes on YouTube for understanding unraid. Follow ibracorp videos as your guide to install all services. Also have a look at https://trash-guides.info/ for setup tips. This 3 should cover almost everything you need to do with unraid.
