For this example I’m using Fedora 33, and will describe how to upgrade to 34. In-place upgrades work as far as two versions back, anything further will require intermediate steps. Update all packages for the current version before you start, then restart the system to make sure you’re on the latest kernel. Prerequisite: we need … Read more
I’ve been playing with various configurations of my software RAID and thought I’d start again from scratch. The obvious question then was, how would I remove my previous efforts? This seems to be different depending on the distribution, so here’s what worked for me in Fedora 33. I’m assuming here that my RAID is /dev/md1. … Read more
In my previous article I’ve explained how to setup a software RAID with mdadm. This was a RAID 5 setup with 3 drives, and in this article we’ll take a look how to expand it with a 4th drive, increasing its overall size.

The firewall-cmd tool has a neat feature in that it knows what ports are used for certain services. This is handy for things like web server ports which our tired brains may forget from time to time (hint: it’s 80 for http and 443 for https). Even without knowing those numbers, we can still open … Read more
I was building a Fedora server with an old laptop, a Samsung Q330 to be precise. I’m surprised it runs Fedora 33 so well (it wasn’t happy with CentOS 8 at all). I wanted it to remain on at all times, even when the lid is closed. Sadly there was no easy way in GNOME … Read more
