The Raspberry Pi platform continues to excel, and the latest iteration has some interesting changes. In this video, Jay and Tom will discuss all the details.
I wanted to test out a rack mount for Raspberry Pi clusters, and that search brought me to the 19″ 3U Rack Mount made by GeeekPi. So, as always, I decided to give you guys my thoughts. It’s not going to win any style awards, but it DOES rack 14 Raspberry Pi’s. Check out this review for more.

Are you looking to build your very own Raspberry Pi-based Network Attached Storage (NAS) for your network or homelab? In this video, we’ll take an in-depth look at the features and functionality of the Argon EON Pi NAS case, a case designed for Raspberry Pi that transforms it into a NAS. You’ll see the the build process, and we’ll also demonstrate how to install and configure OpenMediaVault, a popular open-source NAS operating system, to maximize the capabilities of your build. This is definitely a fun project, so check it out!
Every computer needs an operating system – and the Raspberry Pi is no different. Primarily, the Raspberry Pi boots from an SD card. But how do you write an operating system to that SD card? Well, if you’re just starting out – then this is the video for you!
Normally, I like to make videos for Linux and Container-related things – it’s my favorite way to teach and inform. But some things don’t translate as well to videos, and this is one of them. Recently, I ran into an issue that I’ve been trying to solve for some time, where initializing a Kubernetes cluster on Ubuntu 22.04 seems to fail, specifically on the Raspberry Pi. Although I did ultimately find something while searching the web that led to my resolving this, search results were generally unhelpful, and neither was Stack Overflow. So what I wanted to do, was to create this article just so I could make sure that anyone else Googling for answers does find something.
Here’s the issue I ran into. For some reason, initializing Kubernetes clusters on Ubuntu 22.04 fails on the Raspberry Pi. More specifically, Flannel doesn’t seem to launch, with it stuck on “CrashLoopBackoff” most of the time. And not only that, the coredns pods will tend to stay stuck on “ContainerCreating” for eternity. Another symptom is that you’ll find errors in /var/log/syslog complaining about /run/flannel/subnet.env not being found. Oh, and another symptom. RPC errors will be mentioned in the syslog as well, and also complains about not being unable to create the sandbox.
Blogs and howto’s mention many “fixes” for this issue, but for me I didn’t have any luck there. Some of them will have you create the /run/flannel/subnet.env file manually – but you shouldn’t have to do that, it’s not your job. (That file should be created automatically). I’ve seen at least one blog post mention the order matters regarding when you apply Flannel (nonsense) and not to be outdone, the classic “remove the directory and reboot” trick that also never seemed to work for me.
So, what’s the fix?
Are you ready?
Here you go…
sudo apt install linux-modules-extra-raspi
Yeah, that’s literally it. I’m not kidding. See for yourself. You’re all set. Profit. Enjoy. I know, right?!
Thanks to thiscompletely unrelated bug report that gave me the idea to install this package and ultimately led to my writing this article. It’s my sincere hope that this blog post finds its way into the Google searches of whoever out there needs this.
The Turing Pi 2 is quite an exciting project that might even be a game-changer when it comes to homelab. With it, you can set up Raspberry Pi Compute Modules as individual servers, and even cluster them! The Turing Pi 2 gives you access to many additional features that Compute Modules wouldn’t normally have access to, such as mPCIe, SATA, and more. This gives you access to build a data-center in a box, and Jay gives it a first-look on the channel in this video.
Happy New Year! In their first podcast of 2022, Jay and Tom talk about the Turing Pi 2. The Turing Pi 2 is a mini-ITX board that supports up to four Raspberry Pi Compute Modules and/or Nvidia Jetson modules, effectively giving you a “data center in a box”. Check out this episode for some thoughts on how this might be a game changer for homelab.
With the recent release of Pop!_OS 21.10, a version for the Raspberry Pi was also released. In this video, I’ll check out the new Pi spin and give you my thoughts.
EVICIV was awesome and sent me over a brand new Raspberry Pi display so that I could review it, and that’s exactly what I did. In this video, I’ll give you my thoughts on this display and whether or not I can recommend it.
After watching the review, check out the EVICIV display here.
52pi sent their 19″ Raspberry Pi rack mount over to the studio, so as always I gave it a full review. In this video, I’ll talk about the pros and the cons so you can make a decision for yourself as far as if this product will fit your Pi-server use-case.
If interested, check out the 52pi 19″ Rack Mount here.
Raspberry Pi is an awesome platform, the only limit is your imagination. If you want to turn your Pi into a desktop, the DeskPi aims to help you do exactly that. In this video, I’ll review the DeskPi Pro v2 and give you my thoughts.
Thanks to Linode for sponsoring this video, check them out here and get your very own Linux server!
Tom visited the LearnLinuxTV studio recently to present Jay with an awesome gift – a 3D Printed Raspberry Pi Rack that he and his crew built! In this video, we’ll talk a bit about the build and give you our thoughts. This build is awesome!
