Install Debian on a 2Big Network

This page could be relevant for all the Orion-based LaCie boards.

Boot custom installer

In the following process, you should replace ${NAS_IP} with correct IP regarding your network configuration. ${ipaddr} and ${serverip} are automatically set by clunc.

  • Connect to U-Boot using network console with clunc:

As a preliminary step, you must export the installer image via a tftp server. U-Boot will use this way to load the installer image into RAM.

$ ./clunc -i ${NAS_IP}

2Big Network

A minimal system can be used to prepare disks and to install Debian distribution. A such sytem (kernel+initramfs) is available standard image or Fixed ID image. The initramfs only embed enssential software: busybox, mdadm and mke2fs. Note that the total image size (kernel+initramfs) must not exceed 2MB. The LaCie stock U-Boot is not able to load images largest than 2MB.

  • Connect to U-Boot using network console with clunc:
$ ./clunc -i ${NAS_IP}
  • Edit U-Boot env variables (don't do this if you use the fix_id kernel):

Log into the installer

First, you need to guess the installer address IP (delivred by a DHCP server). You could use tools like dhcpdump. Example:

 $ sudo dhcpdump -i eth0
 [ snip ]
 OPTION:  50 (  4) Request IP address        192.168.0.16
 [ snip ]

Then, you can simply connect to the installer using telnet:

$ telnet 192.168.0.16
Trying 192.168.0.16...
Connected to 192.168.0.16.

Partition Disks

Using a custom debian installation on the 2BigNetwork allows great flexibility with the partition structure. The only caveat is that the kernel _must_ be on partition 6 of one or both of the drives, usually both to make the drives swappable. The startup of the initial ram fs will search for a root filesystem on all RAID and regular disk partitions, and if one is found, will switch to it and complete the boot sequence from there.

If you didn't change the bootargs variable in U-Boot, the rootfs must be on partition 7.

Use the supplied fdisk to partition the disk. An example scheme is below

Running on a single 500GB disk with no RAID

Device Boot      Start         End      Blocks   Id  System      Mount Point
/dev/sda1               1        2433    19543041   83  Linux       /
/dev/sda2            2434        2556      987997+  83  Linux       swap
/dev/sda3            2560       60801   467828865   83  Linux       /data
/dev/sda4            2557        2559       24097+   5  Extended
/dev/sda5            2557        2558       16033+  83  Linux       unused
/dev/sda6            2559        2559        8001   83  Linux       kernel image

A dual disk configuration with RAID

Using the same partition but with sda1 and sdb1 making md0 for /, and sda3 and sdb3 making md1 for /data

Create the RAID arrays using the mdadm command:

mdadm -C /dev/md0 -l 1 -n 2 /dev/sda1 /dev/sdb1
mdadm -C /dev/md1 -l 1 -n 2 /dev/sda3 /dev/sdb3

Format the / filesystem as ext3 with:

mke2fs -j /dev/sda1 (or /dev/md0 if using RAID)

Format the /data fielsystem as ext3 with:

mke2fs -j /dev/sda3 (or /dev/md1)

Install kernel

Providing that an internet connection is available, installation of the kernel is as simple as:

2Big Network 2

wget ftp://lacie-nas.org/kernel/kirkwood/uImage_2.6.38-rc4_kirkwood_lacie_miniroot -O /dev/sda6
wget ftp://lacie-nas.org/kernel/kirkwood/uImage_2.6.38-rc4_kirkwood_lacie_miniroot -O /dev/sdb6

2Big Network

  • If using the regular kernel
wget ftp://lacie-nas.org/kernel/orion/uImage_2.6.38-rc4_orion_lacie_miniroot -O /dev/sda6
wget ftp://lacie-nas.org/kernel/orion/uImage_2.6.38-rc4_orion_lacie_miniroot -O /dev/sdb6
  • If using the kernel with fixed id
wget ftp://lacie-nas.org/kernel/orion/uImage_2.6.38-rc4_orion_lacie_net2big_fix_id_miniroot -O /dev/sda6
wget ftp://lacie-nas.org/kernel/orion/uImage_2.6.38-rc4_orion_lacie_net2big_fix_id_miniroot -O /dev/sdb6

Install rootfs

After the basic rootfs is installed, the system can be booted and used as a regular debian system.

  • Create some useful directories
mkdir /mnt
mkdir /mnt/root
mkdir /data
  • Mount / and /data
mount /dev/sda1 /mnt/root
mount /dev/sda3 /data
  • Download the rootfs into /data
cd /data
wget ftp://lacie-nas.org/images/rootfs-sid.tar.bz2
bunzip2 rootfs-sid.tar.bz2
tar xf rootfs-sid.tar -C .
mv rootfs-sid/* /mnt/root
  • Copy the console device
cp -a /dev/console /mnt/root/dev
  • Unmount and reboot
umount /mnt/root
umount /data
reboot

The NAS should now start the the roofs on /dev/sda1. The rootfs does not contain a telnet daemon, instead it uses ssh

  • SSH into the NAS
ssh root@IPADDRESS

From here on, the NAS can be treated and configured as a regular debian system.

Initial Configuration

  • Set a root password
root@sid-arm:~# passwd 
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully
  • Automatically mount /data

Using your preferred editor (nano is available), edit /etc/fstab to automatically mount the /data partition and setup the swap

# UNCONFIGURED FSTAB FOR BASE SYSTEM
/dev/sda3       /data   auto    defaults        0 0
/dev/sda2        swap   swap    defaults        0 0
  • Create the /data directory and mount it
mkdir /data
mount /data

* Update the apt database
apt-get update
  • Install ntpdate to set the correct time on startup
apt-get install ntpdate
ntpdate pool.ntp.org

Set up the network

  • Set a static IP address so you always know where to find your NAS on the network

Edit /etc/network/interfaces and replace

iface eth0 inet dhcp

With

iface eth0 inet static
      address 192.168.1.9
      netmask 255.255.255.0
      network 192.168.1.0
      broadcast 192.168.1.255
      gateway 192.168.1.1

Using your preferred settings where appropriate

  • Set your hostname

Edit /etc/hostname and enter your preferred name

  • Set up /etc/hosts to ensure proftpd works

Edit /etc/hosts and add

127.0.0.1 localhost
192.168.1.9    lacie-nas

Changing your IP address appropriately

Useful Services

SAMBA

  • Install the packages
apt-get install samba

A basic configuration

  • Edit /etc/samba/smb.conf to share the /data directory with public read access
[data]
  comment = NAS Data
  read only = yes
  guest ok = yes
  path = /data
  • For the sake of simplicity, set the server to *share* level access
####### Authentication #######
# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.
 security = share

FTP

  • Install Proftpd
apt-get install proftpd

When asked, choose to start as a service, not through xinetd

  • Configure the service to load on startup
update-rc.d proftpd defaults
  • Add a user and make them owner of the /data directory
root@lacie-nas:~# adduser ftpuser
Adding user `ftpuser' ...
Adding new group `ftpuser' (1001) ...

MediaTomb UPNP AV Server

At the time of installation, the Mediatomb package in debian sid required an unavailable libavtil package, so this needed to be installed manually.

wget http://ftp.us.debian.org/debian/pool/main/f/ffmpeg/libavutil49_0.5.2-6_armel.deb
dpkg -i libavutil49_0.5.2-6_armel.deb

Then, install the Mediatomb package

apt-get install mediatomb

And set it to startup automatically

update-rc.d mediatomb defaults

Configure the default parameters for the mediatomb server. Set the interface to listen on, and start the user as root, becuase otherwise it doesnt start properly. Edit /etc/defaults/mediatomb like

# Defaults for MediaTomb initscript
# sourced by /etc/init.d/mediatomb
# installed at /etc/default/mediatomb by the maintainer scripts

#
# This is a POSIX shell fragment
#

# Set whether the daemon should be started. Set this value to anything
# but 'yes' to enable the daemon
NO_START="no"

# Additional options that are passed to the daemon.
OPTIONS=""

# The network interface for MediaTomb to bind to and for which the multicast
# routing entry should be added; "" if the route shouldn't be added at all.
# For example: INTERFACE="eth0"
INTERFACE="eth0"

# The route command and arguments to be used if INTERFACE is defined.
# These variables should normally be left unmodified.
ROUTE_ADD="/sbin/route add -net 239.0.0.0 netmask 255.0.0.0"
ROUTE_DEL="/sbin/route del -net 239.0.0.0 netmask 255.0.0.0"

# The user and group that MediaTomb should be run as.
USER="root"
GROUP="root"

Create a directory for the mediatomb database

mkdir /data/.mediatomb

And configure mediatomb to use it and to start the web interface by editing /etc/mediatomb/config.xml

  <server>
  <ui enabled="yes" show-tooltips="yes">
    <accounts enabled="yes" session-timeout="30">
      <account user="mediatomb" password="mediatomb"/>
    </accounts>
  </ui>
  <name>MediaTomb</name>
  <udn>uuid:f0b15445-f01e-4c97-987a-406b6d908ef3</udn>
  <home>/data/.mediatomb/</home>

The address of the mediatomb webserver can be seen in the log

cat /var/log/mediatomb.log
2011-02-23 13:57:51    INFO: MediaTomb Web UI can be reached by following this link:
2011-02-23 13:57:51    INFO: http://192.168.1.3:49152/

Troubleshooting

  • Depending the LaCie U-Boot version, the savenv command could fail: as a solution you can use a a dedicated net2big kernel image with machine ID set to 526 (Marvell LSP unique number for all the customer boards).
  • If you are having problems with fix ID or made a mistake in the environment run

resetenv
