Building a Home Server with TrueNAS

— 1206 words —

After this article was written, FreeNAS was rebranded to TrueNAS.

A few months ago I got gripped with server fever. I’d had a raspberry pi for a while, but I could never find a meaningful use for it. I’d tried running plex, etc, but the pi3 would choke after a bit and sputter out.

One day I decided enough was enough: it was time to build a more beefy server. (and I found a compelling use for the pi!)

Current FreeNAS server information

My Goals

I had a few goals I wanted to achieve:

  1. be relatively future-proof

  2. host a plex server

  3. be able to spin up multiple VMs for various reasons like testing ansible scripts

  4. potentially host games for me and my brother

If all you want to do is host Plex/jellyfish, a raspberry pi should suffice. As long as your media isn’t hvec x265. Before I built this server I had two 2tb drives plugged into my raspberry pi, and other content was fine for the most part.

The Requirements

I don’t have space in my home for a rack for a server, due to both the size and noise. That immediately eliminated a lot of build paths that I saw.

The ideal spot for the server was my living room, so I needed a relatively low profile server- and a quiet one.

The remaining requirements were:

  • at least 8 hard drive bays

  • a relatively modern/beefy cpu

  • low(er) power consumption

I felt like 8 drives (+1 or 2 ssds) was enough for future expansion, even with RAID-10 taken into account. I went with a mirrored structure so I could replace drives without heavy rebuild times, and so I could easily expand the pool if necessary. I started with 6 drives, so I have a zpool with 3 vdevs of 2 drives each.

Part List

What I thought was going to be a relatively simple task turned into a huge amount of research… I spent most of my time on iXsystems’ community forum and /r/homelab on reddit. The people on iXsystems’ forum were very helpful and detailed. However, most of the information for iXsystems is based around used intel boards. Much less material is available if you’re like me and are interested in newer AMD cpus.

So how did I narrow it down? I did what I always do: make a spreadsheet. There are simply way too many options presented to figure what cpu/mobo to choose without spreadsheet analysis. Without further ado:

The total comes out to around $632. I don’t know why anyone would build a server without getting some sort of UPS/APC as well.

The total was $676 for these parts, with $291 for the memory alone. DDR4 ram with ecc isn’t cheap. For comparison, a Xeon E5-2650 V2 goes for around $70 on ebay, with significantly cheaper DDR3 ram.

I’ve used the ryzen setup for 3+ months now with no issues.

So I was already at $1,300, before purchasing hard drives. I bought 6 Western Digital Red 4TB drives initially, @ $100. Later on I got 2 more drives, and another stick of ram.

Altogether, it was $1300 for the parts + $800 for the drives, or ~$2100 in total.

I didn’t go with a used intel board because of the higher power usage and less powerful specs. This made my build much more expensive, but also more future proof.


I adapted my jail setup and structure from this gist, and installed rancheros via this guide.

I currently have 20 jails running, and 5 docker containers running in RancherOS (which runs in a VM with 2 cpus and 4GB memory).

Why jails over docker? Convenience, I guess. It’s far easier for me to muck around in iocage jails than it is to inspect and debug docker containers. Unfortunately this does mean if I lose my server, I’d have to recreate all those jails… but setting them up in the first place was pretty easy once I learned how rc.d worked.

Services that I run:

  -> data backup
  -> grabs subtitles in multiple languages, hooks into radarr/sonarr
  -> reverse proxy to some of these services
  -> radicale
  -> ui for plex plugins
  -> offlineimap + cron
  -> feeds into prometheus on the raspberry pi
  -> digital document store
  -> media catalogue + streaming
  -> monitors local shows for for bazarr subtitle grabbing
  -> monitors local movies for for bazarr subtitle grabbing
  -> seamlessly sync files between computers
  -> modern irc client. I used to use znc+weechat, but I got
     tired of weechat's ux. thelounge is simple and pretty.

Several services use databases, so I elected to set aside jails for them.


I also run 3 instances of minecraft via PaperMC, a high performance fork of Spigot. The main jail runs Waterfall (a fork of bungeecord) along with a hub instance. Waterfall acts as a proxy and lets one access multiple servers within a network.

My docker services:

  -> a wiki with changes automatically git pushed
  -> a fork of gollum with user logins
insekticid/docker-piwiki (matomo)
  -> self-hosted analytics (tracking andrewzah.com)
  -> respects requests to not track user
  -> self-hosted website backup, similar to archive.web
  -> self-hosted, more powerful version of IFTTT
  -> allows local volume mounts in portainer/rancheros

A Use for the Raspberry Pi

Once I built the server, I had no use for my raspberry pi3 and 4. Until I learned about prometheus and grafana.

Having metrics and a dashboard is awesome, but if my server crashes, I no longer have access to the metrics… So they have to be run somewhere else! This is where the raspberry pi comes in- it just sits on my local network ingesting traffic.

Unfortunately, node_exporter doesn’t seem to export hdd temperature values, which is pretty important. I’ll probably have to write a simple script to pull those values and host another metrics target for prometheus.

Why FreeNAS?

FreeNAS has extensive documentation. and *BSDs are nice. ZFS and RAID are nice. Free Software is nice.

If I didn’t use docker so heavily I would likely use FreeBSD or OpenBSD for my personal computers as well instead of Debian.

Overall the process of building a server was pretty fun, but I’m glad I’m done with that for the foreseeable future. I didn’t self-host that much when I began, but once I started adding services I started thinking about everything I could self host.
