Install {{{distro}}} {{{version}}} ({{{codename}}}) on Buffalo LinkStation Mini

WARNING!

There is a possibility that you could brick your NAS with these instructions. Please make sure that you read the entire page carefully. These instructions require disassembly of your Linkstation Mini which may void your warranty or cause severe damage to the hardware. Proceed at your own risk.

Linkstation Mini

Prerequisites

Buffalo LinkStation Mini (this process worked on model LS-WS1.0TGL/R1, but other models should work as well)
Computer with SATA drive interface and internet capability which can also boot a CD-ROM (most modern computers meet this requirement)
Ubuntu 9.04 Desktop Edition CD-ROM (download and burn from http://releases.ubuntu.com/jaunty/ubuntu-9.04-desktop-i386.iso)

Overview

First Phase
- Remove the hard drives from the LinkStation and connect them to the SATA interface of a PC.
- Use a live CD-ROM of Ubuntu to partition and format the hard drives, install Gentoo, and prepare the {{{distro}}} bootstrap files.
Second Phase
- Reassemble the LinkStation, boot it, and login as root to complete the {{{distro}}} bootstrapping process.
Third Phase
- Remove the hard drives from the LinkStation (again) and connect them to the SATA interface of a PC.
- Use a live CD-ROM of Ubuntu to remove Gentoo and install Ubuntu from the completed bootstrapping process.
Fourth Phase
- Reassemble the LinkStation and boot into a fresh {{{distro}}} system.

Note: Do not attempt to execute these commands as a script. Instead, copy and paste each block of commands into a shell window and monitor the resulting output for errors.

First Phase

On Linkstation

Move power switch to "off" position
Disconnect power cable
Disconnect network cable
Remove cover (per instructions at Disassemble_the_LS_MINI)
Use a pen to mark hard drive near ethernet port (this is /dev/sda)
Remove both hard drives

On Computer

Shutdown
Power off
Attach both hard drives to SATA interface
Ensure that marked hard drive (/dev/sda) is connected to the first SATA interface
Ensure that second hard drive (/dev/sdb) is connected to the second SATA interface

Boot Ubuntu 9.04 Desktop Edition CD-ROM
Specify language (English)
Enter live mode ("Try Ubuntu without any change to your computer")
Open a new terminal window (Applications | Accessories | Terminal)

Start a new bash shell with root privileges

sudo bash

The following commands will delete all existing partitions on both hard drives and reconfigure them as follows...

Partition	Mount	Size	Type	Description
1	boot	128MB	fd	linux raid autodetect
2	swap	256MB	82	linux swap
3	root	12GB	fd	linux raid autodetect
4	srv	100%	fd	linux raid autodetect

WARNING!

The following commands will void the warranty on your LinkStation Mini by removing all existing partitions on both hard drives (/dev/sda and /dev/sdb). You will not be able to revert to stock firmware after you run these commands. It is recommended that you backup your existing partitions before executing these commands. Proceed at your own risk.

Remove all existing partitions and repartition both drives

PARTITION1_SIZE=128MB
PARTITION2_SIZE=256MB
PARTITION3_SIZE=12GB
swapoff -a
echo -e "d\n1\nd\n2\nd\n3\nd\n4\nn\np\n1\n\n+${PARTITION1_SIZE}\nn\np\n2\n\n+${PARTITION2_SIZE}\nn\np\n3\n\n+${PARTITION3_SIZE}\nn\np\n\n\nt\n1\nfd\nt\n2\n82\nt\n3\nfd\nt\n4\nfd\nw\n" | fdisk /dev/sda
echo -e "d\n1\nd\n2\nd\n3\nd\n4\nn\np\n1\n\n+${PARTITION1_SIZE}\nn\np\n2\n\n+${PARTITION2_SIZE}\nn\np\n3\n\n+${PARTITION3_SIZE}\nn\np\n\n\nt\n1\nfd\nt\n2\n82\nt\n3\nfd\nt\n4\nfd\nw\n" | fdisk /dev/sdb

Activate swap partitions

mkswap /dev/sda2
mkswap /dev/sdb2
swapon /dev/sda2
swapon /dev/sdb2

Install mdadm package (for administering software raid configuration)

Ignore any "/dev/MAKEDEV not found" failure message -- it is a bug which does not affect this process.

export DEBIAN_FRONTEND=noninteractive
apt-get update
apt-get -q -y install mdadm
unset DEBIAN_FRONTEND

Create RAID devices (/dev/md11, /dev/md13, and /dev/md14)

cd /mnt
umount /mnt/md13/boot
umount /mnt/md13
umount /mnt/md14
mdadm --stop /dev/md11
mdadm --stop /dev/md13
mdadm --stop /dev/md14
echo "y" | mdadm --create --verbose /dev/md11 --level=1 --raid-devices=2 /dev/sda1 /dev/sdb1
echo "y" | mdadm --create --verbose /dev/md13 --level=1 --raid-devices=2 /dev/sda3 /dev/sdb3
echo "y" | mdadm --create --verbose /dev/md14 --level=1 --raid-devices=2 /dev/sda4 /dev/sdb4

Format RAID devices

cd /mnt
umount /mnt/md13/boot
umount /mnt/md13
umount /mnt/md14
mkfs.ext3 -F /dev/md11
mkfs.ext3 -F /dev/md13
mkfs.ext3 -F /dev/md14

Mount RAID devices and create required directories

mkdir -p        /mnt/md13
mount /dev/md13 /mnt/md13
mkdir -p        /mnt/md13/boot
mount /dev/md11 /mnt/md13/boot
mkdir -p        /mnt/md14
mount /dev/md14 /mnt/md14

Do not change the order of the next 3 blocks. The correct order is Gentoo (GenLink), kernel, initrd.

Install Gentoo root file system (GenLink)

cd /mnt/md13
rm -f /mnt/md13/GenLink-stage3.1_arm9-1.1_rc3-20080923.tar.bz2
wget http://downloads.buffalo.nas-central.org/LSPro_ARM9/Distributions/Genlink/Rootfs/GenLink-stage3.1_arm9-1.1_rc3-20080923.tar.bz2
tar --extract --verbose --same-permissions --bzip2 --file GenLink-stage3.1_arm9-1.1_rc3-20080923.tar.bz2
rm -f /mnt/md13/boot/boot

Install 2.6.27 kernel (uImage.buffalo) - Tried and tested, but limited modules ( no usb-storage support )

cd /mnt/md13
rm -f /mnt/md13/LS-Mini-2.6.27-rc6lsmini-2008-10-09-23-39-29.tbz2

tar --extract --verbose --same-permissions --bzip2 --file LS-Mini-2.6.27-rc6lsmini-2008-10-09-23-39-29.tbz2

Optionally install 2.6.32.2 kernel (uImage.buffalo) - has many more kernel modules

The associated kernel config file can also be found here: http://buffalo.jpfast.net/2.6.32.2/LS-Mini-2.6.32.2-2010-01-06-20-41+0900-config.bz2

cd /mnt/md13

tar --extract --verbose --same-permissions --bzip2 --file initrd-md13-armv5tejl-softfloat-1.0.tbz2

Configure Gentoo resolv.conf

cp /etc/resolv.conf /mnt/md13/etc/resolv.conf

Configure Gentoo fstab (file system table - mount points)

rm -f /mnt/md13/etc/fstab
echo "/dev/sda2   none      swap   sw,pri=1                     0  0" >>/mnt/md13/etc/fstab
echo "/dev/sdb2   none      swap   sw,pri=2                     0  0" >>/mnt/md13/etc/fstab
echo "/dev/md13   /         ext3   noatime,errors=remount-ro    0  1" >>/mnt/md13/etc/fstab
echo "/dev/md11   /boot     ext3   noatime,errors=remount-ro    0  0" >>/mnt/md13/etc/fstab
echo "/dev/md14   /srv      ext3   noatime,errors=remount-ro    0  0" >>/mnt/md13/etc/fstab
echo "shm         /dev/shm  tmpfs  noatime,nodev,nosuid,noexec  0  0" >>/mnt/md13/etc/fstab
echo "tmpfs       /tmp      tmpfs  noatime,nodev,nosuid,noexec  0  0" >>/mnt/md13/etc/fstab

Install debootstrap package (for downloading {{{distro}}} bootstrap files)

cd /
export DEBIAN_FRONTEND=noninteractive
apt-get update
apt-get -q -y install debootstrap
unset DEBIAN_FRONTEND

Download {{{distro}}} {{{release}}} ({{{codename}}}) bootstrap files

cd /mnt/md14
rm -rf /mnt/md14/bootstrap
mkdir -p /mnt/md14/bootstrap
debootstrap  --foreign  --arch armel  --include ssh,ntp  {{{release}}}  /mnt/md14/bootstrap  {{{source}}}

echo "ALL : 127.0.0.1" >>/mnt/md13/etc/hosts.allow

Configure fstab (file system table) Important: do not change the last column for on RAID (md) devices, any other values will prevent the device from initializing!

rm -f /mnt/md13/etc/fstab
echo "/dev/sda2   none      swap   sw,pri=1                     0  0" >>/mnt/md13/etc/fstab

export SED_FILE='/mnt/md13/etc/shadow'
export SED_SEARCH='^\s*root\:\*?\:'
export SED_REPLACE='root:$6$bmlbpJYn$xAgZr6KxoRLjDcPZNDBcnMF52gZrU7xkib43LhSlAvzVS4OqmiHaxB0GInPtoaPQ2FguHQQuxM95cMfvUnYn31:'

cat /proc/mdstat
sync

Sync and unmount RAID devices

cd /mnt
sync
umount /mnt/md11
umount /mnt/md13
umount /mnt/md14

Shutdown

shutdown -h now

Power off
Remove hard drives

Fourth Phase

On LinkStation

Reassemble
Connect network cable
Connect power cable
Move power switch to "on" position
Wait for 15 minutes for initialization to complete (later reboots will be ready much faster)
Login with ssh as root (password = lsmini)

Configure default system locale (adjust LANG variable to suit your needs, format = language_COUNTRY.ENCODING)

export LANG=en_US.UTF-8
locale-gen ${LANG}
update-locale LANG="${LANG}"

Select timezone

dpkg-reconfigure tzdata

Ensure that date and time are correct

date

Change root password to something hard to guess

passwd root

Install mdadm package (ignore MAKEDEV not found failed message)

export DEBIAN_FRONTEND=noninteractive
apt-get update
apt-get -q -y install mdadm
unset DEBIAN_FRONTEND

Add /dev/sdb partitions to RAID devices (/dev/sdb is intentional-- the device names get switched somehow)

mdadm --add /dev/md11 /dev/sdb1
mdadm --add /dev/md13 /dev/sdb3
mdadm --add /dev/md14 /dev/sdb4

Add user (never login as root, use sudo command instead)

export USER_NAME=visitor
adduser ${USER_NAME}
