• Disassembling Raid on Hetzner Without Rescue Mode

    tl;dr - Disassembling the default-installed RAID1 on Hetzner dedicated servers so you can give one drive to Rook (Ceph underneath) to manage is doable without going into Hetzner rescue mode if you just shrink the cluster to one drive (credit to user forstschutz on StackOverflow), then remove the second. I’m a huge fan of Hetzner dedicated servers and in particular their Robot Marketplace. Long story short, discovering the robot marketplace thanks to someone on HN opened my eyes to the world of affordable dedicated servers (I’ve also written about hetzner in some previous posts).

  • Kicking The Tires On Fathom

    tl;dr - I set up Fathom for an application running in my small kubernetes cluster. It was easy but required a little hackery to properly init fathom (in particular creating the root user) Recently I came across Fathom (usefathom/fathom on github) thanks to restoreprivacy.com’s google-alternatives page. They also got posted on Hacker News, which was cool to see. Up until now I’ve been using Matomo (formerly Piwik) for my website analytics (for example on this blog) – it’s got a bucketload of features and is relatively easy to setup along with having some good defaults.

  • Dedicated server rescue (RAID + Grub2 issues)

    tl/dr; an update (sudo pacman -Syu) to a server I manage running Arch messed up the boot process of my server, due to interaction between RAID and GRUB, and I stumbled my way through debugging it. WARNING If you find yourself with this problem, make sure to read all the way to the end, because I take some steps that I think made things worse half way through (in particular running grub-install and in-effect wiping out boot)

  • Ansible Is Awesome

    tl;dr - There are lots of ways to get smarter about how you deploy. Ansible is one choice, it’s not the fanciest, but it’s amazing. NOTE This is not an introduction to ansible, please check out their official documentation if you want that. For most of my projects, I use a GNU Make Makefile based build process. I do that because it’s cross-platform, pretty well suppported/known (for people who build software), and easy to standardize on no matter what project I’m working on.
