Advent of Code 2024 – Day 10 – Hoof It

In this video series, I try to challenge myself with the Advent of Code trials. Each solution will be published to Github, and I hope you will learn something from my coding mistakes and perhaps send some code my way on how you have done these challenges. I know by reading code, so this is…

In this video, we talk about how to set up a Ceph RADOS block device. We will mount this device on a Linux client and talk about what block device is used for and the difference between a Ceph file system. We also touch on iSCSI and its usage around block devices. Moreover, we talk…

I’m trying to solve all the Advent of Code puzzles in this video series.

We look into using the cephadm tooling to bootstrap and configure a small cluster with 3 drives and multiple hosts. We go into how cephadm administers different resources and shares them between hosts. Installing main host First we need curl in order to fetch the cephadm application sudo apt install -y curl Then we download…

We look into ceph storage building our own cluster using the ceph storage engine. A cluster usually contains multiple monitors, object storage daemons, managers and metadata servers. We talk about what their role is and how to install machines to handle this. We also cover what requiredments a ceph cluster has.

We look into how to build a Debian package from source after we have done some patching of a bug that we needed to solve in the original package. Debian is a great system with good tools for building packages.
