Problem with RAID and LVM2 using Lacie Ethernet Drive


Hi everybody, I have a problem in my lacie ethernet disk, I have several private files on it and I am not able to access it. I searched several tutorials but none worked for me.

First tried this (http://www.linuxquestions.org/questi...untu-569507/):
Code:
# aptitude install lvm2
# modprobe dm-mod
# vgscan
Reading all physical volumes. This may take a while ...
Stopped here

Then I tried another how to:
Code:
# aptitude install mdadm
Code:
# sfdisk -l /dev/sdb
WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util sfdisk doesn't support GPT. Use GNU Parted.

Disk /dev/sdb: 243201 cylinders, 255 heads, 63 sectors/track
Warning: The partition table looks like it was made for C/H/S=*/256/63 (instead of  243201/255/63). 
For this listing I'll assume that geometry.
Unit = cylinders of 8257536 bytes, blocks de 1024 bytes, counting from 0

   Device Boot Start End #cyls #blocks Id System
/dev/sdb1          0+ 242251- 242252- 1953514583+  ee  GPT
/dev/sdb2          0       -       0          0    0  Empty
/dev/sdb3          0       -       0          0    0  Empty
/dev/sdb4          0       -       0          0    0  Empty
Code:
# mdadm --assemble --run /dev/md0 /dev/sdb8
mdadm: no recogniseable superblock on /dev/sdb8
mdadm: / dev / sdb8 has no superblock - assembly aborted
I stopped here


Now do not know what to do, I've listed the partitions with lvmdiskscan, returned this:
Code:
   /dev/ram0 [64.00 MiB]
   /dev/ram1 [64.00 MiB]
   /dev/root [292.36 GiB]
   /dev/ram2 [64.00 MiB]
   /dev/ram3 [64.00 MiB]
   /dev/ram4 [64.00 MiB]
   /dev/ram5 [64.00 MiB]
   /dev/sda5 [5.73 GiB]
   /dev/ram6 [64.00 MiB]
   /dev/ram7 [64.00 MiB]
   /dev/ram8 [64.00 MiB]
   /dev/ram9 [64.00 MiB]
   /dev/ram10 [64.00 MiB]
   /dev/ram11 [64.00 MiB]
   /dev/ram12 [64.00 MiB]
   /dev/ram13 [64.00 MiB]
   /dev/ram14 [64.00 MiB]
   /dev/ram15 [64.00 MiB]
   /dev/sdb1 [1.00 MiB]
   /dev/sdb2 [192.00 MiB]
   /dev/sdb3 [1.00 MiB]
   /dev/sdb8 [1.82 TiB] LVM physical volume
   1 disk
   20 partitions
   0 LVM physical volume whole disks
   1 LVM physical volume
Code:
# pvscan
  PV /dev/sdb8                      lvm2 [1,82 TiB]
  Total: 1 [1,82 TiB] / in use: 0 [0   ] / in no VG: 1 [1,82 TiB]
Code:
# lvscan
Returned nothing

As you can see the /dev/sdb8 is what I need to recover.
Does anyone have any idea what I can do? I need of these files.

Code:
parted /dev/sdb print

hmmm. The partition is labeled as RAID, but there is no superblock. Which should it be?
