OS recommendations

Its new homelab time. And with that, potentially a new OS time too.

I currently am very happy with Debian and Docker. The only issue is I am brand new to using data redundancy. I have a 2 bay NAS I’ll use, and I want the two HDDs to be in raid 1.

Now I could definitely just use ZFS or BTRFS with Debian, and be able to use Docker just like I do currently.

Or I could use a dedicated NAS OS. That would help me with the raid part of this, but a requirement is Docker.

Any recommendations?

I run Debian with zfs. Really simple to set up and has been rock solid for it too. As far as I can tell all the issues I've had have been my fault.

ZFS looks like it uses a lot of RAM, but you can get away without it if you need too. It's basically extra caching. I was thrilled to use it as an excuse to upgrade my ram instead.

Mdadm has a little more setup then zfs, as far as I'm concerned. You need to set your own scrubbing up whereas zfs schedules it's own for you. You need to add monitoring stuff for both though.

I've considered looking into the various operating systems designsd for this, but they just don't seem to be worth the effort of switching to me.

Dust0741 OP ,

Any recomended monitoring solutions? Or just proxmox and grafana?

someonesmall ,

I can recommend dockprom. It comes with grafana preconfigured.

someonesmall ,

I can also recommend zfs on debian. Even if you only using two disks you will be still protected from bit rot.

Proxmox ZFS with plenty of ram. (ZFS is ram heavy)

Bog-standard Debian with LVM. LVM can also do RAID, but you could also do mdadm below LVM if you prefer. Keep it simple.

possiblylinux127 ,

Not as powerful as btrfs or zfs

Maestro ,

ZFS isn't built-in. I don't know enough about btrfs to recommend it.

I was in a similar boat. Initially, I ran debian with docker but later on decided to check out unraid. It’s pretty easy to get setup, and you have a lot of docker containers pre-configured, so you can just click and install. I have it notify me whenever something goes on with it, but outside of that, I don’t tinker much with it.

Only two weird things about it though…

  1. You dont install unraid. Instead, you run it through a usb. More specifically, the usb has a specific config that’ll then load everything to your memory.
  2. Recently, they redid their pay structure so not too familiar with the changes but you do have to pay for unraid.

Unraid and Truenas are pretty popular. Openmediavault is less popular, but a pretty simple system based on Debian.

TrueNAS SCALE expects you to deploy Kubernetes clusters, it is unfortunately not meant for running plain Docker. You can jump through hoops to get it working but I personally gave up and ended up running a VM on top of TrueNAS just to run Docker on it.

I don’t know about Unraid though and OpenMediaVault felt a bit unpolished the last time I used it and I can’t attest for its ZFS support.

Mrb2 ,

Truenas scale is switching to docker compose. I found this out when the truecharts catalog suddenly stopped working. more info

Holy molly, I wasn’t expecting this! Well, I guess I’ll try that out once Electric Eel’s released

golli ,

I am currently using Openmediavault for my NAS and can confirm that with an official plugin so far I havent had any issue with my ZFS pool (that I migrated from trueNAS scale since I didn’t like their kubernetes use and truecharts, but as someone mentions they seem to switch to docker).

Otherwise I am happy as well, but I am far from a poweruser.

variants ,

I’ve been happy with unraid, super simple to use and the community apps makes it easy to find and install docker containers

dwindling7373 ,

I’m very new to the whole ordeal but to my knowledge ZFS and, less so BTRFS are a bit too rigid for my setup, I’m personally looking at Debian with mergerFS and SnapRAID.

someonesmall ,

ZFS is rigid? Please explain

hendrik ,

Debian and the standard linux mdraid?

catloaf ,

This. Don’t make it unnecessarily complicated.

Dust0741 OP ,

Do you mean mdadm? raid.wiki.kernel.org/index.php/A_guide_to_mdadmIf not can I have a link?

hendrik ,

Yes, as the other people pointed out, that's what I mean. The standard Linux software RAID (also called MD RAID)

It's proven, battle-tested, pretty robust and you don't rely on any specific vendor formats or any hardware for that matter. The main point would be to keep it simple. You could use BTRFS or ZFS or all kinds of things. But it only introduces additional complexity and points of failure. And has no benefits over a plain mirror (what the RAID1 does) if we're talking about just 2 devices. At least it served me well in the past. Contrary to cheap hardware RAID controllers and also BTRFS which also let me down once. But a lot of development went in to that since then and the situation might have changed. But mdraid is reliable anyways.

How about bitrot?
