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 may void your warranty. Proceed at your own risk.



Linkstation Mini

Contents


Overview

The following process converts a Buffalo Linkstation Mini (model LS-WSxxxxGL/R1) into a GNU/Linux server running Debian version 6.0.5 (Squeeze) with the Debian 6.0 Linux kernel (version 2.6.32-45). No disassembly required. Both RAID1 (Mirroring) and RAID0 (Striping) configurations are supported. Here is how the process works:

  1. Use ACP Commander software to establish Telnet session with device
  2. Uncouple secondary drive partitions from existing RAID configuration
  3. Partition and format secondary drive, install Debian 6.0 (Squeeze), and prepare for initial boot
  4. Reboot device, establish SSH session with device, and complete installation


Requirements

  1. Buffalo LinkStation Mini models LS-WSxxxxGL/R1 running stock firmware (LS-WSXxxxxTL/R1 models will not work)
    • If your device has already been modified to run another operating system and/or firmware, you should revert to stock firmware
    • This process was tested with model LS-WS1.0TGL/R1, but other models may work as well
  2. Ubuntu 10.04 Desktop Edition CD-ROM (download and burn this disc image)
  3. Computer which can boot the Ubuntu 10.04 Desktop Edition CD-ROM and access the network successfully (most modern computers meet this requirement)


Instructions

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

    Prepare Device

  1. Disconnect power cable from device
  2. Disconnect all USB devices (and keep them disconnected for the duration of this process)
  3. Move device switch to "on" position
  4. Attach device to network
  5. Connect power cable to device
  6. Wait for device to finish booting (no blinking lights)
  7. Open device web interface (factory default address is http://192.168.11.150, or use the IP address assigned by your network)
  8. Login (user = admin, password = password)
  9. Nuvola apps important.png 
    WARNING!

    The next step will erase all data on your Linkstation Mini. It is recommended that you backup your existing data. Proceed at your own risk.


  10. Remove existing RAID configuration (Disk Management | RAID Setup | RAID Array 1 | Change RAID Array ...)
  11. Create new RAID1 (mirroring) array (Disk Management | RAID Setup | RAID Array 1 | RAID Mode: RAID1 ...)
  12. Wait for "Building RAID Array" to complete
  13. You may proceed immediately after the array has been built (you do not need to wait for the drive check to complete)

  14. Boot Ubuntu 10.04 Desktop Edition CD-ROM on computer
  15. Select language as desired (English)
  16. Click on "Try Ubuntu 10.04 LTS" (to use Ubuntu without making any changes to your system)
  17. Open a new terminal window (Applications | Accessories | Terminal )
  18. Start a new bash shell with root privileges
    sudo bash
    
    
  19. Install OpenJDK (for running ACP Commander software)
     apt-get update
     apt-get -q -y install openjdk-6-jre
    
    
  20. Download ACP Commander software (acp_commander.jar)
     wget http://downloads.buffalo.nas-central.org/Users/rpinchbeck/lsmini/acp_commander.jar
    
    
  21. Determine IP address of device and assign it to environment variable (substitute appropriate IP address)
     IP_ADDRESS=192.168.11.150
    
    
  22. Instruct device to enable Telnet and remove root password

     swapon /dev/sdb2
    
    
  34. Create RAID volumes
     echo "y" | mdadm --create --verbose /dev/md11 --level=1 --raid-devices=2 missing /dev/sdb1
     echo "y" | mdadm --create --verbose /dev/md13 --level=1 --raid-devices=2 missing /dev/sdb3
    
    
  35. Format RAID volumes
     mkfs.ext3 -F /dev/md11
     mkfs.ext3 -F /dev/md13
    
    

  36. Install Debian System

  37. Mount RAID volumes
     mkdir -p                /mnt/lsmini
     mount -t ext3 /dev/md13 /mnt/lsmini
     mkdir -p                /mnt/lsmini/boot
     mount -t ext3 /dev/md11 /mnt/lsmini/boot

    WARNING!

    Do not modify the last column of /etc/fstab... any value other than zero will cause the device to hang on startup. Basically, the system fails to detect the RAID volumes, sends the failure message to the console, waits for keyboard input (that can never arrive), and cannot respond to pings or any other network traffic. Don't find out the hard way.


  46. Configure mount points (/etc/fstab)
     echo "/dev/sdb2   none      swap   sw,pri=1                     0  0"  >/mnt/lsmini/etc/fstab
     echo "/dev/md13   /         ext3   noatime                      0  0" >>/mnt/lsmini/etc/fstab
     echo "/dev/md11   /boot     ext3   noatime                      0  0" >>/mnt/lsmini/etc/fstab
     echo "none        /dev/shm  tmpfs  noatime,nodev,nosuid,noexec  0  0" >>/mnt/lsmini/etc/fstab
    
    
  47. Configure network name resolution (/etc/resolv.conf)
     cp -a /etc/resolv.conf /mnt/lsmini/etc/resolv.conf
    
    
  48. Change root password (new password = lsmini)
     SED_FILE='/mnt/lsmini/etc/shadow'
     SED_SEARCH='^\s*root\:\*?\:'
     SED_REPLACE='root:$6$bmlbpJYn$xAgZr6KxoRLjDcPZNDBcnMF52gZrU7xkib43LhSlAvzVS4OqmiHaxB0GInPtoaPQ2FguHQQuxM95cMfvUnYn31:'
     sed -r "s~${SED_SEARCH}~${SED_REPLACE}~" -i "${SED_FILE}"
    
    
  49. Workaround bug in Debian 6 (/etc/network/run links to /dev/shm/network, but directory is missing, which prevents network interfaces from starting)
     mv /mnt/lsmini/etc/network/run run.original
     mkdir /mnt/lsmini/etc/network/run
     touch /mnt/lsmini/etc/network/run/ifstate
    
    
  50. Prepare for reboot (Overwrite factory-installed boot files with custom ones)
     cd /mnt/lsmini
     rm -rf /boot/*
     cp -a /mnt/lsmini/boot/* /boot/
    
    
  51. Wait for RAID synchronization to complete
     while egrep -iq '(recovery)|(resync)' /proc/mdstat; do
         clear
         cat /proc/mdstat
         sleep 5
     done
     clear
     cat /proc/mdstat
     sync
    
    
  52. Unmount RAID volumes
     sync
     cd /mnt
     umount /mnt/lsmini/boot
     umount /mnt/lsmini
    
    
  53. Reboot device
     sync; reboot; logout
    
    

  54. Configure Debian System

  55. Wait for device to finish booting (no blinking lights)
  56. Assign new IP address to environment variable
     IP_ADDRESS=192.168.1.77
    
    
  57. Use SSH to login as root (password = lsmini)
     ssh root@${IP_ADDRESS}
    
    
  58. Change root password to something hard to guess
     passwd root
    
    
  59. Select timezone
     dpkg-reconfigure tzdata
    
    
  60. Ensure that date and time are correct
     date
    
    
  61. Make sure primary drive is not in use (/dev/sda)
     if hdparm -z /dev/sda ; then echo; echo "PRIMARY DRIVE READY (/dev/sda)"; echo; else grep sda /proc/mounts /proc/mdstat; echo "Please check that /dev/sda is not in use"; fi;
    
    
  62. Repartition primary drive (must have same partition sizes as secondary drive)
     PARTITION1_SIZE=128MB
     PARTITION2_SIZE=512MB
     PARTITION3_SIZE=12GB
     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
    
    
  63. Format and activate swap partition on primary drive
     mkswap /dev/sda2
     swapon /dev/sda2
    
    
  64. Automatically mount swap partition during boot
     echo  "/dev/sda2   none      swap   sw,pri=2                     0  0"  >>/etc/fstab
    
    
  65. Add primary drive partitions to RAID volumes (/dev/md11 and /dev/md13)
     echo "y" | mdadm --manage /dev/md11 --add /dev/sda1
     echo "y" | mdadm --manage /dev/md13 --add /dev/sda3
    
    
  66. Create large RAID volume on /dev/md14 (substitute RAID level as desired; 1=Mirroring, 0=Striping)
     RAID_LEVEL=1
     echo "y" | mdadm --create --verbose /dev/md14 --level=${RAID_LEVEL} --raid-devices=2 /dev/sda4 /dev/sdb4
    
    
  67. Format large RAID volume
     mkfs.ext3 -F /dev/md14
    
    
  68. Mount large RAID volume (as /srv)

  69. Automatically mount large RAID volume during boot (as /srv)
     echo "/dev/md14   /srv      ext3   noatime                      0  0" >>/etc/fstab
    
    
  70. Clean up mdadm.conf (allow detection of all RAID volumes during boot)
     SED_FILE='/etc/mdadm/mdadm.conf'
     SED_SEARCH='^\s*ARRAY\s+.*$'
     SED_REPLACE=''
     sed -r "s~${SED_SEARCH}~${SED_REPLACE}~" -i "${SED_FILE}"
     mdadm --quiet --detail --scan >>/etc/mdadm/mdadm.conf
    
    
  71. Disable login terminals (prevent error messages in /var/log/syslog every 5 minutes about /sbin/getty respawning too fast)
     SED_FILE='/etc/inittab'
     SED_SEARCH='(^\s*[0-9]+\:[0-9]+\:respawn\:\/sbin\/getty\s+[0-9]+\s+tty[0-9]+\s*$)'
     SED_REPLACE='#\1'
     sed -r "s~${SED_SEARCH}~${SED_REPLACE}~g" -i "${SED_FILE}"
    
    
  72. Allow USB flash drives formatted with the VFAT file system (Windows) to be mounted automatically in /media/usb
     SED_FILE='/etc/usbmount/usbmount.conf'
     SED_SEARCH='^(\s*FILESYSTEMS\s*=\s*\")(.*)(\"\s*)$'

  73. Configure package sources (/etc/apt/sources.list)
     echo "deb      http://ftp.debian.org/debian  squeeze          main contrib"  >/etc/apt/sources.list
     echo "deb-src  http://ftp.debian.org/debian  squeeze          main contrib" >>/etc/apt/sources.list
     echo "deb      http://security.debian.org    squeeze/updates  main contrib" >>/etc/apt/sources.list
