Setup RAIDZ on Ubuntu Server 20.04 LTS

In this walkthrough we'll be using 4 brand new Seagate IronWolf Pro 10TB 7200rpm 256MB hard drives to setup a ZFS storage pool (RAIDZ 10).

1. ZFS

If you don't have ZFS already installed go ahead and run

sudo apt install zfsutils-linux

2. Disk Identifier & Sector sizes

Before we do anything with the drives we need the disk identifier and sector size for each drive for step 3.

ZSH (using Oh My ZSH) on Manjaro Linux

0. If ZSH is not already installed on your Manjaro system you can do it with the command:

sudo pacman -Syu zsh

You do not need to install manjaro-zsh-config and all the other related packages like zsh-syntax-highlighting, zsh-history-substring-search, zsh-autosuggestions, etc., as we will use Oh My Zsh.
