Advent of Code – Day 16

We are in our new linux environment and create ACL, some tools for process managment and the sed tool to update files with expressions.

We look into Ubuntu MiniCloud which is a tool to easily spin up a cluster with Ceph, OVN and LXD. This enables you to run workloads over a large amount of servers with and easy to use web interface.

Looking into the configuration file and talk about what the different parameters mean

We build some important tools, the M4 compiler and libraries needed by the system.

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

After a critical failure, we look into resizing an OSD in our Ceph environment. Unfortunately, the drive is entire, so resize of the OSD was the only option to start the service.
