Homelabbing: A really nice hobby

You are about to witness this blog’s first rant. Proceed with caution, or not at all if you’re so inclined. Without further ado: Piss off. No, I don’t need this many machines. I want this many physical machines. Every single one of them was a very conscious decision driven by a clear design goal.

Here, I will be going into the details of the problem I am having and how I solved it. The problem So until not very long ago at all, I only had a single server, with everything running in a couple of Docker containers.

Ceph MON Migration

In the course of spreading my homelab over a couple more machines, I finally arrived at the Ceph cluster’s MON daemons. These were running on three Ceph VMs on my main x86 server up to now. In this post, I will describe how I moved them to three Raspberry Pis. While the cluster was up the entire time. First, a couple of considerations: MON daemons use on average about 1GB of memory in my cluster My cluster, and most of my services, went down during the migration....
