There is a way to "unstock" Mini without disassembly.
There is a possibility that you could brick your NAS with these instructions. Please make sure that you read the entire page carefully. It is easy to recover your bricked LS Mini, but you have to disassemble it. Disassembling may void your warranty or cause severe damage of the hardware!You will have only one chance to make it. Take time, it will take about hour or more.
If you were unsuccessful, don't get upset: you can go "via disassembly".
First of all you need to get telnet access to your LS Mini:
http://buffalo.nas-central.org/index.ph ... k_FirmwareWhen in, you need to kill all unneeded processes with help of
killall and
ps.
You must come to a state similar to this:
Code:
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:
Code:
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)
In the next step we will free /dev/sdb from stock firmware: LS Mini uses it as a boot drive.
Stock firmware cannot be reverted after this step!Code:
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 mounted
Now we need to repartition /dev/sdb:
Code:
root@LS-WSGL:~# if hdparm -z /dev/sdb > /dev/null; then echo; echo DRIVE READY; echo; fdisk /dev/sdb;\
else grep sdb /proc/mounts /proc/mdstat; echo Please check that sdb is not in use; fi;
DRIVE READY
The number of cylinders for this disk is set to 60801.
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)

Create RAID1 arrays for new system:
Code:
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$i missing; done;
mdadm: /dev/sdb1 appears to contain an ext2fs file system
size=1003904K mtime=Thu Oct 9 10:13:37 2008
mdadm: size set to 72192K
Continue creating array? mdadm: array /dev/md11 started.
mdadm: size set to 1959808K
mdadm: array /dev/md13 started.
mdadm: size set to 486215168K
mdadm: array /dev/md14 started.
root@LS-WSGL:~# cat /proc/mdstat | grep md1[1234]
md14 : active raid1 sdb4[0]
md13 : active raid1 sdb3[0]
md11 : active raid1 sdb1[0]
Prepare filesystems and swap, it will take some time:
Code:
root@LS-WSGL:~# for i in 11 13 14; do mkfs.ext3 -F /dev/md$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
Install bzip2:
Code:
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
Create and mount root of your new firmware:
Code:
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#
Download and extract latest
Genlink rootfs image:
Code:
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.bz2
Now chroot into you fresh Gentoo:
Code:
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:
Code:
sh-3.2# pwd
/
sh-3.2# wget http://buffalo.jpfast.net/LS-Mini-Minimal-2.6.27-rc6lsmini.tbz2
sh-3.2# tar xvjf LS-Mini-Minimal-2.6.27-rc6lsmini.tbz2
sh-3.2# wget http://buffalo.jpfast.net/initrd-md13.tbz2
sh-3.2# tar xvjf initrd-md13.tbz2
Edit fstab to match your disks:
Code:
nano -w /etc/fstab
Code:
/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 mountpoint for /dev/md14 later)
Now recheck everything and reboot your Linkstation Mini into a fresh Genlink install:
Code:
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:
Code:
user@host ~ $ ssh root@<ip-address-here>
