Hmm .. ok.
There is the 5Big Network 2
(I have) and then there is a newer version called 5Big NAS Pro
(I have worked with already at my office).
The newest firmware for the Network 2 is 126.96.36.199 (with a size of ~75mb) at the moment.
NAS Pro has Firmware 188.8.131.52 (with a size of ~120mb) .. so its definitely different! (It also has other Ports, 2x USB2.0, 2x USB3.0 and VGA(!)) The NAS Pro also uses an Atom-CPU and 4GB Ram, wheras the Network 2 has an ARM-CPU and 512mb Ram.
My 5Big Network 2
came without disks. I bought the disks seperately (some Seagate consumer disks), so there was definitely no LaCie software on the disks!
On first boot it took about 5-10min .. so yes, probably it installed the FW on the disks in this time ..
I also found the Info about how the 2Big Network 2
partitions the disks. I have to confirm similarities for my 5Big:
* sda1: extended, 980 Mb
* sda2: xfs, md linear/raid1, user data, the remaining part of the disk
* sda5: swap, md raid1, 130 Mb
* sda6: Linux kernel U-Boot Image, 8 Mb
* sda7: ext3, md raid1, minimal root partition, 8 Mb
* sda8: ext3, md raid1, original firmware partition, 130 Mb
* sda9: ext3, md raid1, snapshots/upgrades partition, 696 Mb
* sda10: filled with zeroes (may be used for an alternate kernel), 8 Mb
Anyway, that doesn't help me recovering my system, as it seems FW on flashrom AND disks seems to be broken
I tried clunc but it says clunc-open is not available. If I run "make" it always puts some cc-errors on my linux machine (Ubuntu 14.04 64bit). I didn't investigate further, but as clunc seems to work over IP, it doesn't help me much anyways.
Thanks, Mijzelf, for the information on the raid-structure! It calms me down a lot to know that the data can be read with a normal linux pc also.
Only thing is, I never worked with linux software raids before, so I don't know much about it ... But I am sure the internet will be helpful
I am on vacation the next couple of days, so I let all this wait until I am back. Perhaps Lacie support has some helpful advice in the meantime. After the last days work I believe I have to send it in for repair anyways .. and I still hope it will be covered by warranty
