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 such an exciting thing for me.
We look into the Ceph scrubbing process, how it works, what to expect when something goes wrong. Some techniques to handle issues and work around them. We also talk about the difference between deep scrubbing and normal scrubbing. Last but not least we talk about filesystem scrubbing.
I did not have Grafana dashboards that worked in my Ceph installation. Hence, I had to install Prometheus and Grafana manually and then configure the dashboards to show up in my Ceph cluster dashboard screens.
In this video we create a invoice template that looks alot like an invoice from one of my first videos. We will go through all the different parts of a invoice that is required and how to go from a data XML to an PDF.
We are looking into installing Redhat 9 without any interaction using Kickstart. Kickstart is a tooling that gives you configuration options to prepare your system and manage the installation flow.
We look into high availability using Heartbeat and DRBD. Heartbeat is a software to monitor and failover when a machine is unresponsive and DRBD can help you replicate data between machines making your setup highly available. This solution can help you doing maintenance work without downtime. Git repository: https://ift.tt/2YdYVbQ Please follow me on twitter Tweets…
