VLANs offer a powerful way to divide a physical network into multiple logical networks. This can be useful if your host has a limited number of interfaces or you want to limit the usage of network ports on your switch. In this tutorial, we’ll demonstrate how to set up a VLAN-tagged interfaces on top of physical network interface on Ubuntu 22.04 using NetworkManager Text User Interface (nmtui).

Virtual Local Area Networks (VLANs) offer a powerful way to segment networks and enhance security. This guide demonstrates how to configure VLANs on FreeBSD 14.1. We will cover the creation of VLAN interfaces, IP addressing, and routing, enabling you to isolate different network segments.

mdadm, which is a Linux Software RAID, is not inferior to a typical hardware RAID controller, and just like a hardware controller – enables us to swap physical disks inside the RAID array. It requires executing some commands indeed, but the whole process still seems to be pretty straightforward.
Usually, we replace a disk in RAID when it starts failing, but there might be scenarios, where you just want to swap mechanical SATA disks in RAID with SSDs, one by one, for better performance, without reinstalling the whole OS.

Debian is a powerful, multipurpose, and super stable Linux distro, however, in my humble opinion, its installation wizard was never a strong point of this Linux distribution, making it pretty difficult to install for beginners. While the standard setup with just a single disk is still relatively digestible for most users, the more sophisticated setup involving RAID with LVM might be pretty hard and arduous. The purpose of this tutorial is to help you go through the whole installation procedure smoothly and painlessly.
In this tutorial, I present Debian 11 (Bullseye) installation based on MD-RAID, configured in Mirroring mode, with an additional Hot Spare drive and LVM partitioning on top of it.
