Lenovo ix2-dl corrupted firmware

What a pain in the $%^&*( ass.

Lenovo has no concept of using a md5 checksum on a file to confirm its integrity before you flash it and end up with a corrupted NAS like me.

AND to top it off, Lenovo support only offers a destructive way to reflash the NAS, double %^&*()^& in the ass.

So, initially I thought the drives were set up as a zfs disk set – installed the zfs needed debs on my debian jessie system only to find out all the lenovo disk set is is a linux md raid set, so  (pulling this from my bash history)


Disk /dev/sdd: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt
Disk identifier: 276C4C51-BFA8-4E33-AB51-FC7033AA6D56

Device Start End Sectors Size Type
/dev/sdd1 65536 42008575 41943040 20G Microsoft basic data
/dev/sdd2 42008576 3907028991 3865020416 1.8T Microsoft basic data

Once I figured out it was just a md linux raid set, it was easy peasy to import :

root@dell:~# mdadm --assemble --run /dev/md1 /dev/sdd2 
mdadm: /dev/md1 has been started with 1 drive (out of 2).

# DOH! no lvm2 installed on the system
root@dell:~# mount /dev/md1 /mnt
mount: unknown filesystem type 'LVM2_member'
root@dell:~# pvscan
-su: pvscan: command not found
root@dell:~# apt-get install lvm2

pvscan, vgscan, and lvscan bought it LV into devicemapper

root@dell:~# pvscan
 PV /dev/md1 VG bad2c48_vg lvm2 [1.80 TiB / 0 free]
 Total: 1 [1.80 TiB] / in use: 1 [1.80 TiB] / in no VG: 0 [0 ]
root@dell:~# vgscan
 Reading all physical volumes. This may take a while...
 Found volume group "bad2c48_vg" using metadata type lvm2
root@dell:~# lvscan 
 ACTIVE '/dev/bad2c48_vg/lv3140cc7e' [1.80 TiB] inherit

Mounted it up, 
root@dell:~# sudo mount /dev/bad2c48_vg/lv3140cc7e /mnt

bingo - now I can find 1.8TB worth of space elsewhere to rsync all that %^&*( data off 
so I can follow Lenovo's destructive NAS rebuild.
