How to cleean your system so it doesnt explode ?

Why? - Storytelling

I got an error recently on jellyfin, a sudden crash. It was because a file couldn’t write ? And in fact it was due to the fact that my system storage is completly full. Thanks to Cyberduck awesome logs detail on upload, I saw that the file was not able to write. I thought it was due to CyberDuck (stupid me…), then I tried nano, and there I saw, when editing, that the file was pointting to SWAP. THANKS SWAP, you saved my system from exploding while flying..

Building your first Homelab

I want to put in place a Homelab server, to run all my small home apps like a Media center server (plex, jellyfin, emby..? who knows!) in a first step.

This is a Repo that recap’s every step that I will achieve to setup my homelab. This will allows me to remember each step of the architecture, automatized the best as possible, and also don’t forget how everything is working.
