Linux on a BBS2 (Tranquil PC)

How to install Linux on a Bare Bone Server from Tranquil PC, with mirrored disks and logical volumes.

Goal

When replacing an old server-PC , the new one had to fulfill the following requirements:

Introduction


The Tranquil Bare Bone Server (BBS2 advanced) is choosen for the hardware, for the ability to contain 5 disks, and even more on USB. It includes hardware mirroring, which is not used because it requires paires of equal disks.

Ubuntu Linux is used as Operating system (replaces Debian that works fine, but seems end-of-life). It allows mirroring of disk partitions, allowing us to use a any disk available, not necesserally paired.

For reliability, all data is mirrored:

The system can survive a crash on any of the disks, even a boot partition.

LVM (logical volume manager) is used to turn available odd-shaped physical disks into usable virtual disks.

Why this site

First of all, it is my method of organizing my notes. Now I can find, and even read them again sometime.
The need for that is emphasized by the lack of information on the Internet about Grub2. That costs a lot of time ...!

First a small description of the BBS server (hardware), mirroring and logical volumes (software):
open folder About the BBS2
open folder Mirroring, logical volumes, virtual disks

Installation

The rest of his manual describes how to to install Linux with mirrored and logical volumes,

For mirroring you need 2 or more disks, not necesseraly equally sized. USB disks can be included in mirrors as well.

Using locical volumes, there is no relation anymore between the physical disk sizes, and the used virtual disk sizes anymore.
You can add/replace physical disks when available, and you can resize logical disks later when desired.
(As long as the total of logical disks sizes is smaller than half the total of physical disk size (mirrored, remember ?).)
