Hi Guys, this place it's fantastic, are many days that i read here about recovery DIY, :twisted:
For first, scuse my bad fucking Eng, but i'm a very lazy boy.. :roll:

At work we had a Iomega NAS.. :oops:

The 4th disk was gone, (for smart ctl) and for a stupid guy 3 disk of 4 was been reinitialized!
:lol: :lol: :lol: :lol: :lol: :lol: :|
For first i did a DD copy for each disk to another quartet of 1Tb Disk..
And i was in this situation:

2Gb 997Gb
1) /dev/sda1 - -
2) /dev/sdb1 - -
3) /dev/sdc1 - -
4) /dev/sdd1 /dev/sdd2

With a calc in the hand and many hours with HexEditor i found the start of the data on 1,2,3 disks...
Obviusly the data start it's not the partition start.. i established that first 10mb of disk 1 2 and 3 was zero filled... :geek:
(i don't remember indexs but i'll post all my tables tomorrow)

I made same partition table for all 4 disk, cloning the structure of 4th:
2Gb 997Gb
1) /dev/sda1 /dev/sda2
2) /dev/sdb1 /dev/sdb2
3) /dev/sdc1 /dev/sdc2
4) /dev/sdd1 /dev/sdd2
Finded old dumps of mdadm i rebuilded the RAID5 from the NAS with SSH...
mdadm --create --assume-clean ecc...

I obtained a readable volume of 2.7Gb..
Mounted the RAID5 on PartedMagic..

checked with photorec and i obtained 15mb zip archives and a lot of big jpeg so i can say that RAID work very fine..
:mrgreen: :mrgreen: :mrgreen:

Searching the partition...
{... skipped all my mental masturbations on LVM group that i resolved with a loopback from the offset that i find in the system partition of the nas...}

I know that, the partition is an XFS, i found the start of the superblock :shock: :shock:
It was on 4th disk 8-)
but... :'
Recovering and trying with many programs, forcing the xfs_repair -L and ecc..
i can see only few file, that are intact, but i can't find my ISCSI disk of 5Gb...
i found another disk of 100Gb but it's not what i want..
In addiction the internal data of Virtual ISCSI disk make my life terrible with a RAW recovery...
So any suggestion?
Is there a method to restore lost XFS inode?
Knowing the start of my ISCSI Disk, can i copy it contiguously?
