Over the weekend, I migrated one of the Ceph VMs in my Homelab over to a physical host. This time around, instead of buying a completely new machine, I recycled most of my old 2018 era home server. It’s an old AMD A10-9700E, meaning the 35W TDP variant. I have noted some thoughts on reusing this old machine here. Mounted in the rack, the machine looks like this: Server mounted in the rack, without Ceph OSD disks attached....
I was recently introduced to the excellent Wolf 359 audio drama. It’s the story of the crew of a space station orbiting a distant star, with good humor and interpersonal drama as well as some suspense/horror sprinkled in. I have a small set of other podcasts as well, first and foremost the great British History Podcast. Up to this point, I had mostly listened on my phone, during train rides, but also via my browser during Saturday morning household chores....
I updated my Nomad and Consul clusters recently. Especially Consul was a large jump, getting from 1.13.5 to 1.15.1. After about three days, I suddenly started getting 500: Internal server error from a lot of my services. In this article, I will be going into the debugging process and explain a little bit about what Consul Connect is and how it works. Why Consul Connect? So Consul Connect, or Consul Service Mesh, creates a sort-of overlay network to connect services running on multiple machines, in a secure manner....
I had a random thought today, triggered, by all things, by a short training on Reduce, Reuse, Recycle at work. This is the principle of first looking for the potential to not produce anything. Then to look for a new use for something old that has already been manufactured. And only then, as a final step, to recycle the thing. I, and probably many other Homelabbers, have quite a bit of older hardware laying around....
This is the next post in the Current Homelab series, where I give an overview of what my lab is currently looking like. This time, I will be talking about my storage layer, which is mostly made up of Ceph. I chose Ceph around spring 2021, when I decided to go from a baremetal+docker-compose setup to a VM based setup with LXD. At the time, my main storage consisted of a pair of WD Red 4TB disks for my main storage requirements, and a 60GB crucial SATA SSD for my server’s root FS....
