You will have only one chance to make it without disassembly. Take time, it will take about hour or more.
If you were unsuccessful, don't get upset: you can go "via disassembly".
Open up and prepare stock firmware
First of all you need to get telnet access to your LS Mini: Open Stock Firmware
When in, you need to kill all unneeded processes with help of killall and ps commands.
You must come to a state similar to this:
root@LS-WSGL:~# ps | grep -v SW
PID Uid VmSize Stat Command
1 root 572 S init
1012 root 200 S /sbin/dhcpcd -L /etc/dhcpc -h LS-WSGL -t 15 -x -y -z
1048 root 652 S syslogd -m 0
1050 root 380 S klogd
1054 root 676 S /usr/sbin/inetd
1865 root 620 S /sbin/getty -L ttyS0 115200 vt100
2201 root 384 S telnetd
2203 root 1256 S -sh
3682 root 720 R ps
Now check that you have same RAID configuration as I had:
root@LS-WSGL:~# cat /proc/mdstat
Personalities : [raid0] [raid1]
md1 : active raid1 sdb2[1] sda2[0]
5004160 blocks [2/2] [UU]
md10 : active raid1 sda5[0] sdb5[1]
1003904 blocks [2/2] [UU]
md0 : active raid1 sda1[0] sdb1[1]
1003904 blocks [2/2] [UU]
unused devices: <none>Probably you will need to stop one of arrays absent here with mdadm -S
Prepare and repartition one of disks
|
In the next step we will free /dev/sdb from stock firmware: LS Mini uses it as a boot drive.
root@LS-WSGL:~# mdadm -f /dev/md1 /dev/sdb2 mdadm: set /dev/sdb2 faulty in /dev/md1 root@LS-WSGL:~# mdadm -f /dev/md10 /dev/sdb5 mdadm: set /dev/sdb5 faulty in /dev/md10 root@LS-WSGL:~# mdadm -f /dev/md0 /dev/sdb1 mdadm: set /dev/sdb1 faulty in /dev/md0 root@LS-WSGL:~# mdadm -r /dev/md1 /dev/sdb2 mdadm: hot removed /dev/sdb2 root@LS-WSGL:~# mdadm -r /dev/md10 /dev/sdb5 mdadm: hot removed /dev/sdb5 root@LS-WSGL:~# mdadm -r /dev/md0 /dev/sdb1 mdadm: hot removed /dev/sdb1 root@LS-WSGL:~# umount /mnt/* umount: /mnt/array1: not mountedNow we need to repartition /dev/sdb:

There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): p Disk /dev/sdb: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 1 125 1004031 83 Linux /dev/sdb2 126 748 5004247+ 83 Linux /dev/sdb4 749 60801 482375722+ 5 Extended /dev/sdb5 749 873 1004031 82 Linux swap /dev/sdb6 874 60690 480480021 83 Linux Command (m for help): d Partition number (1-6): 1 Command (m for help): d Partition number (1-6): 2 Command (m for help): d Partition number (1-6): 3 Warning: partition 3 has empty type Command (m for help): d Partition number (1-6): 4 Command (m for help): d No partition is defined yet!

Now check that everything is right and write new partition table:

Calling ioctl() to re-read partition table. Syncing disks.
New RAID arrays
Create RAID1 arrays for new system:
root@LS-WSGL:~# for i in 1 3 4; do echo y | mdadm --create --verbose /dev/md$(($i+10)) \
--level=1 --raid-devices=2 /dev/sdb$i missing; done;
mdadm: /dev/sdb1 appears to contain an ext2fs file system
size=1003904K mtime=Thu Oct 9 10:13:37 2008
mdadm: size set to 72192K
Continue creating array? mdadm: array /dev/md11 started.
mdadm: size set to 1959808K
mdadm: array /dev/md13 started.
mdadm: size set to 486215168K
mdadm: array /dev/md14 started.
root@LS-WSGL:~# cat /proc/mdstat | grep md1[1234]
md14 : active raid1 sdb4[0]
md13 : active raid1 sdb3[0]
md11 : active raid1 sdb1[0]
Filesystems and swap
Prepare filesystems and swap, it will take some time:
root@LS-WSGL:~# for i in 11 13; do mkfs.ext3 -F /dev/md$i; done; <skip> This filesystem will be automatically checked every 21 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override. root@LS-WSGL:~# mkswap /dev/sdb2
Create and mount root of your new firmware:
root@LS-WSGL:~# mkdir /mnt/genlink/ root@LS-WSGL:~# mount /dev/md13 /mnt/genlink/ root@LS-WSGL:~# mkdir /mnt/genlink/boot/ root@LS-WSGL:~# mount /dev/md11 /mnt/genlink/boot/ root@LS-WSGL:~# cd /mnt/genlink/ root@LS-WSGL:/mnt/genlink#
Firmware image
First install bzip2:
root@LS-WSGL:~# cd / root@LS-WSGL:/# wget http://buffalo.jpfast.net/bzip2.bin.arm.tgz root@LS-WSGL:/# tar xvzf bzip2.bin.arm.tgz
Download and extract latest Genlink rootfs image:
root@LS-WSGL:/mnt/genlink# wget http://buffalo.nas-central.org/*/GenLink-stage3.1_arm9-*.tar.bz2 root@LS-WSGL:/mnt/genlink# tar xvjpf ./GenLink-stage3.1*.tar.bz2Now chroot into your fresh Gentoo:
root@LS-WSGL:/mnt/genlink# mount -t proc proc proc/ root@LS-WSGL:/mnt/genlink# cp /etc/resolv.conf etc/resolv.conf root@LS-WSGL:/mnt/genlink# chroot .Install kernel and proper initrd:
sh-3.2# pwd / sh-3.2# wget http://buffalo.nas-central.org/download/LSMini_ARM9/Distributions/Genlink/Kernel/LS-Mini-2.6.27-rc6lsmini-2008-10-09-23-39-29.tbz2 sh-3.2# tar xvjf LS-Mini-2.6.27-*.tbz2 sh-3.2# wget http://buffalo-nas-hacking.googlecode.com/files/initrd-md13-armv5tejl-softfloat-1.0.tbz2 sh-3.2# tar xvjf initrd-md13*.tbz2
Edit fstab to match your disks:
nano -w /etc/fstab
/dev/md13 / ext3 defaults,noatime,errors=remount-ro 0 1 /dev/md11 /boot ext3 defaults,noatime,errors=remount-ro,noauto 0 2 /dev/sdb2 none swap sw,pri=1 0 0 #/dev/sda2 none swap sw,pri=1 0 0 tmpfs /tmp tmpfs size=5m,mode=1777 0 0 shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
(you can create mount point for /dev/md14 later)
Reboot
Now recheck everything and reboot your Linkstation Mini into a fresh Genlink install:
sh-3.2# exit exit root@LS-WSGL:/mnt/genlink# umount proc/ root@LS-WSGL:/mnt/genlink# cd / root@LS-WSGL:/# umount -a root@LS-WSGL:/# reboot; logout
Wait 3-5 minutes, blue power led should shut off.
Wait a couple minutes more, and then ssh to the Mini:
user@host ~ $ ssh root@<ip-address-here>
Password: lspro

Then make a mount point for the disk: I chose the name /mnt/big
GenLSPro / # mkdir /mnt/big GenLSPro / # nano /etc/fstab
Add an /etc/fstab entry and save the file:
/dev/md14 /mnt/big ext3 defaults,noatime,nodiratime,errors=remount-ro 0 2
Then mount the directory:
