LVM Install Guide

   Warning

This page is currently a work in progress 

Introduction

This tutorial will show you how to install Funtoo, including the rootfs, on logical volumes. This guide is meant to complement the regular Funtoo Installation Guide. It is recommended to open it in another tab, window ect.. and follow along with it as we will only be documenting the steps that are different or in addition to the regular guide.

Introduction to LVM

LVM (Logical Volume Management) offers a much more flexible way of managing your storage devices. Not only does it allow you to resize your volumes while the system is still up, it also frees you from having to decide exactly how many or how big volumes need to be at the time of installation.

For a detailed tour and introduction to LVM please consult the LVM Fun page.

Live CD

Please read the Live CD section in the regular guide. The only thing you need in addition to the requirements it mentions is the sys-fs/lvm2 package or equivalent. If you use System Rescue CD, it includes the lvm2 package.

Prepare Hard Disk

Preparing the hard disk for an LVM install isn't much different from a normal install except that we won't be creating a bunch of partitions as we are going to use logical volumes instead. All we need is a /boot partition, if your using gpt, you'll need the GRUB partition, and the rest of the space will just be one big partition which we'll create our logical volumes out of.

   Note

We're using the previous mentioned setup to keep things simple in this guide. We are also assuming your only using one hard disk though LVM supports adding multiple hard disks and partitions to a volume group. Please adapt these instructions to suit your needs

The regular install guide does a good job explaining MRB, GPT, and gdisk/fdisk so we won't be repeating that here. Read through the Prepare Hard Disk section and create the previous mentioned partitions. If your following our setup your partiotion table should look like the following when completed:
