Restoring Data from Corrupted RAID on Lacie 5Big Network v2

[BlinkGuy06]

Hi,

After an upgrade of the capsule (5big-Network-2_2.2.10.1.capsule) from officiel Lacie website, the NAS doesn't boot anymore (still having blue light blinking)... Webinterface doesn't show up. So I try Factory reset (using front button and using Lacie Network Assistant) like indicated in the manual. But same thing the NAS doesn't boot and webinterface doesn't show.

After few rescearch i found fvdw-sl firmware. I tried then to use it for boot and access filesystem using kernel standalone. It's working i'm now on the NAS command line interface.

I have try to mount all my data using "mdadm" and "mountpoint" command. Same it's seems to work. when i try to use "fdisk -l /dev/sdd" or "gdisk -l /dev/sdd", I can see that the partition is corrupted. I have read about "xfs_repair" but i can't found it.

Regarding the fact that my data must be restore, here is my questions :
- How can I manage to compile and install static "xfs_repair" utility on my LACIE NAS? Do you think it will repair my RAID and allow me to restart LACIS OS ?
- I would like to upgrade my NAS to fvdw-sl firmware web interface. But it telling me that my sda disk will be erased... Is it possible to install it without deleting all my data? ( on sd[abcde]2 )... Or can I format my sda hard drive and restore after from fvdw-sl firmware web interface with my 4 others drives?

You can found here result of "dmesg" command : http://pastebin.com/GqHREu4y

Thanks for your help !

Regards

There is a lot of info on this in several posts on this board :tapfoot

Some link to get you going

viewtopic.php?f=26&t=1768&p=13745&hilit=mkfs.xfs#p13745
the last link is contains a minimal version of glibc and shows how to get it working with the standalone kernel
After you managed that you you could try if you can upload xfs_repair in the attachment and put it in the same folder met mfs.xfs is (/sbin), make it executable and see if it runs

About keeping your date while installing fvdw-sl. That will not be possible as we use a different partition structure and file system then the lacie firmware. So if you want to keep your date you will need to make a backup first

xfs_repair.zip is now available here:

Thanks for your quick reply,

I have read about all these posts (except perhaps the last one). But it seems to not fit exactly to what happen in my case.
I will try to use XFS_repair and give you feed back very soon !

Dmesg doesn't agree. All partitions are recognized.
