Installing Archlinux 2014.10.01 on LVM

Installing Arch Linux: Prepare the system

Setup the disks

Use fdisk to create two partitions

fdisk /dev/sda

create new gpt partition table create partition 1, size +256M (n, size +256M) create partition 2, the rest (n, use defaults) change partition 2 to type lvm (t, 23) write and exit

create physical volume

pvcreate /dev/sda2

create volume group

vgcreate arch /dev/sda2

create logical volumes

swap 4GB, root 8GB and the rest for home

lvcreate -L 4G arch -n swap
lvcreate -L 4G arch -n root
lvcreate -l +100%FREE arch -n home

Create file systems

Format the created partitions

mkswap -L swap /dev/mapper/arch-swap
mkfs.ext4 -L boot /dev/sda1
mkfs.ext4 -L root /dev/mapper/arch-root
mkfs.ext4 -L home /dev/mapper/arch-home

Mount the filesystems

Mount the formatted filesystems

swapon /dev/mapper/arch-swap
mount /dev/mapper/arch-root /mnt

Create mountpoints in the new root disk and mount home and boot in it.

mkdir /mnt/{boot,home}
mount /dev/sda1 /mnt/boot
mount /dev/mapper/arch-home /mnt/home

Use standard installation up until mkinitcpio

Add lvm to /etc/mkinitcpio.conf

/etc/mkinitcpio.conf HOOKS="base udev ... block lvm2 filesystems"

Use syslinux bootloader and gptfdisk

pacman -S syslinux gptfdisk
