I replaced my old 1gbs router with a 2.5gbs one from Protectli! It has coreboot which was the ultimate deciding factor for me, even though it came at a premium.

Installing OpenWRT wasn’t difficult, but configuring it correctly to use all the ports took some retries.

I also have been trying to install a pixelfed instance of my own on Podman, but no luck so far; I keep failing at the image building part. I wish they would release images of their own.

Thanks for the reply. Looking at this project now. What reverse proxy did you use? I have regular caddy already as a reverse proxy for other projects and I am wondering how I could use it here as well.

Do you need to do some maintenance to keep the data in the array intact?

I read of some btrfs scrub commands and md checks and such, but I am unsure how often to do them, and what they actually do.

Thanks for the info!

Could you elaborate on btrfs on top of md raid?

This one seems the most likely solution for me.

Powerloss might happen as I don’t have a ups.

And when it comes to mdadm, it just happens to be the first and only redundancy tool I know. I am however open to learn and try new things.

ZFS seems interesting, but: I read that ZFS would require quite a lot of RAM, and I was going for 32 GBs only, would it be enough?

What are the advantages of this over mdadm raid and bcache?

Are there some advantages of btrfs over raid? I understand how raid works but btrfs for redundancy is foreign to me.
