It took me really long time to figure out how to rescue MBWE II. I tested this procedure with 2*500G and 2*1T and they all work perfectly, so i think it should also work for the others. I combine this procedure from many posts in this forum, so I must say thanks to PCnity, Macuser, Z80, and acfischer42, and many other useful posts from which I learn about Linux in general and this wonderful MBWE.
Step1: Follow Rescue Procedure written by PCnity for the both disks: http://mybookworld.wikidot.com/rescue-procedure , but in step 12 instead of replacing /dev/sda4, keep it as /dev/md4, but comment out (put # in front) that line.
Step2: Install both disks to MBWE, go to share storage manager (ping mybookworld to know your MBWE IP address). You will not see storage information now because we haven't created raid yet. But you are able to create a user name and password so you can log in when using SSH in later step
Step 3: Enable SSH using: http://martin.hinner.info/mybook/sshaccess.php
Step 4: to prepare for later step, you should install optware using: http://mybookworld.wikidot.com/optware, and install nano (an editor program)
/opt/bin/ipkg install nano
Step 5: Download putty from http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html and run it (if you are using windows) log in: xxx.1.861.291|eman_resu_ruoy#xxx.1.861.291|eman_resu_ruoy (your MBWE IP), and type your password, now run under super user mode by:
su
mdadm --create /dev/md4 --level=linear --raid-devices=2 /dev/sda4 /dev/sdb4 (if you want raid=linear)
(or # mdadm --create /dev/md4 --level=1 --raid-devices=2 /dev/sda4 /dev/sdb4 (if you want raid=1))
mkfs.ext3 /dev/md4
mount /dev/md4 /shares/internal
mdadm /dev/md3 -a /dev/sdb3
mdadm /dev/md2 -a /dev/sdb2
mdadm /dev/md1 -a /dev/sdb1
now, check your raid:
mdadm -Es
It should show up similar to this (your UUID might be different), note down your UUID for /dev/md4
ARRAY /dev/md4 level=linear num-devices=2 UUID=1f477eda:b9e24a33:29183c1b:f04dc09d
ARRAY /dev/md3 level=raid1 num-devices=2 UUID=cc0255b1:ab6a743e:140ccd5c:a2cc1275
ARRAY /dev/md2 level=raid1 num-devices=2 UUID=e26a4fa6:63a71e7b:9fae57d8:fcad5af4
ARRAY /dev/md1 level=raid1 num-devices=2 UUID=c76782f4:82389a60:dfb9eb54:c349664a
Step 6: Update your mdadm.conf file
/opt/bin/nano /etc/mdadm.conf
replace the UUID in mdadm.conf with those in your raid from previous step. Actually the only number that is different is UUID for /dev/md4
hit Ctrl X then Y, then Enter
Step 7: format your raid again
mkfs.ext3 /dev/md4
Step 8: Edit fstab
/opt/bin/nano /etc/fstab
Remove "#" in front of /dev/md4
Step 9: Adjusting setting for 2 -disk version
/opt/bin/nano /etc/default-settings (change **wdg1nc** to **wdg2nc**)
/opt/bin/nano /var/oxsemi/nas.ini (change **1NC** to **2NC**)
Step 10: If you are not using western digital hard drives, the fan will never run, so you have to activate the fan using http://kyyhkynen.net/stuff/mybook/temperature_monitor.php
Reboot and you are all set
