Lacie 5Big2 Failed After Firmware Update

[unlucky1]

Thanks for e2fsck! Here's the output:

e2fsck 1.41.14 (22-Dec-2010)
e2fsck: No such device or address while trying to open /dev/sdb2
Possibly non-existent or swap device?

Oh dear. It seems only sdc and sdd have a valid partition table. I guess these are the 3th and 4th disk. Have you done anything special with the other disks?

[unlucky1]

No, I didn't touch them. It's a standard 5big2 lacie diskless and I put in the 5 disks and it was all running fine until their %&·"&$/"!!! firmware update!!! What's worse is that they take no responsibility over their mistake! So here I am begging for help from great people like you all in this forum and they just count their money....

On a whim, looking for different responses I tried:

root@(none):/ # e2fsck -y /dev/sdc
e2fsck 1.41.14 (22-Dec-2010)
e2fsck: Superblock invalid, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/sdc

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

This are identical disks, I suppose? In that case you can copy the partition table from the 'good' disk to the bad ones.

Code: Select all

dd if=/dev/sdc of=/dev/sda bs=512 count=20
dd if=/dev/sdc of=/dev/sdb bs=512 count=20
dd if=/dev/sdc of=/dev/sde bs=512 count=20

After that reboot the box, and do a

Code: Select all

cat /proc/partitions

again.

Are they identical though? Is that how this raid works? From hardware, they are all identical. Software, I have no idea!

[Mijzelf]

When the disks are hardware identical, the partition tables are also identical, and so are the firmware partitions (5,6,7,8 and 9). But the contents of the data partitions (2) is different. (Of course. Else you couldn't store more data than on a single disk).

did we scare him off ?

[unlucky1]

No, I'm here. I was looking it up too :/ I am really worried as this data is soooo important not to lose!!

[unlucky1]

I'll give it a try now! Holding my breath! I'll change my profile name to Lucky1 if it works at the end!
