Unbrick a Bricked Lacie Network Space 2

[kouyio]

Hi experts,

FACT: I've bricked my NAS. With honor.

I've tried to unbrick it by deleting it all and reinstall with some low-level commands, using the appropriated wiki page: Installing firmware_on_a_new_disk_(Network_space_2).
I did it all, by using either 1.2.6 files or 1.0.2 ones.
The NAS didn't care ; when powered on, its blue light blinks after a few seconds.

And I'm actually thinking that, after my NAS is back on track again (I sincerely think it will, with your help huh!), I will need to do some nasty stuff in it (activate root ssh, newsgroups client, etc, etc).

SO: Would there be anyone here with enough courage/love/compassion for him to share with me its gzipped NAS partitions so that I can use them as source for rewriting mine?
Ideally, these gzipped NAS partitions would match a SSH-enabled NAS so that I won't have to hack/brink it again? :-)

Thanks for the courage/love/compassion,
A NAS lover

How did you brick it? What happens when you follow the Wiki directions using the 1.0.2 images? (not the 1.2.6 ones, they are stored differently, and should be restored accordingly)

• Does the disk spin up
• Does it request an IP address? (logfiles router)
• Can you ping the box
• What does a portscan say

[kouyio]

What I did:

1. I first tried to SSH it, couldn't, installed a telnet deamon, could connect using telnet, restarted the NAS, then could neither telnet it nor access its web admin console ;
2. So I repartitioned it entirely with fdisk using this tutorial ;
3. I filled the partitions with the gzipped files (1.2.6 files or 1.0.2 ones) ;
4. But once the NAS reassembled, both the network and power cables connected, it doesn't want to start as it did before.

Some answers:

• Does the disk spin up yes it does
• Does it request an IP address? (logfiles router) can't access, my rooter is from my ISP - don't have access to its logs
• Can you ping the box no
• What does a portscan say didn't try since can't ping
• What does the LED do? after 10s, the blue LED blinks up and down every 1s

Well, I restarted the whole procedure so that I'm sure that I didn't miss or mixed anything up.
I created an automated bash script that reformats the whole Lacie NS2 for me. You will find it just below.
I also attached my associated logs.

I will now retest my NAS ; I let you know of the outcome

[kouyio]

Well, seems better now!

It starts, can be pinged. Its admin web interface can be accessed and I see the first-time setup web page.

However, the "Disk configuration" area tells me that it found 0 B of Network Storage. Same thing for the USB Storage.
Thus, I can't use the slider at all, and the setup doesn't go farer.

Seems to me that my /dev/sda2 partition is KO?

Any idea?

[kouyio]

And the solution to this latter problem was in the wiki: http://lacie.nas-central.org/wiki/Insta ... k_space_2)

When you put this disk in your Network Space 2, it should work.
It is possible that the filesystem on /dev/sda2 is not accepted by the NAS. In that case the shares are not visible/accessible, and you can't login on the webinterface (Please wait while loading ...). It seems that mkfs.xfs from modern distro's can generate an incompatible filesystem. The remedy: get shell access, login on the box, and create the filesystem here, and force unicorn to update:

Code: Select all

mkfs.xfs /dev/sda2 -f
rm /etc/unicorn.db
reboot

Mijzelf, thanks mate!

[Mijzelf]

Great that you sorted it. I suppose we'll never know why it didn't work the first time you tried.

BTW, in your script, you don't need to delete all partitions first, just execute a -from the top of my head- 'o' "Create a new, empty Intel partition table".

[deuch23]

Hello, I have a problem. The tutorial does not work with my hard drive of 2 TB. I can not create the partition. Could you help me? thank you

[Mijzelf]

Whet is the error message?

[deuch23]

I copy the downloaded mbr on the hard disk. Then I type the command "fdisk / dev / sdb". Then the message appears WARNING. And when I try to create the partitions it does not


WARNING: Data surperflues ignored in the partition table 7
ignored empty partition (8)

The device has a logical sector size over
smaller than the physical sector size. Adjust the limit
size to the physical sector (or optimal in terms of I / O)
is recommended, otherwise the performance may be affected.

thank you

[Mijzelf]

I suppose that's an 'advanced format' disk? And I also suppose you're using an fdisk version which is aware of this, and denies to create misaligned partitions.
In that case you can switch off that denial (try fdisk --help), but that can have a serious performance penalty. The other option is to skip the MBR, and create the needed partition table manually. Make sure the partitions 6, 7 and 8 and 10 are at least the prescribed size. Bigger is no problem.

[deuch23]

when I try to create partitions without having to copy the mbr. I can not created a logical partition using fdisk

[Mijzelf]

First make an extended partition (sda1), big enough to contain sda5-sda10, then create the logical partitions (which are inside the extended partition), and finally a primary partition (sda2).

[deuch23]

No one has a procedure for a hard disk 2 Tb?

[greekfrixos]

I had the same issues with kouyio.

My NS2 boot procedure was stuck in the beginning with the blue led blinking every second.

I dismount the disk (my files OK) I formatted the disk, and follow the procedure described above.
I did 4 times very carefully but the result was always the same: FAIL The NS2 kept blinking for ever during startup and nothing else.

I was thinking that it was something wrong with the BIOS, or the M/B, or the ROM, so my last chance was to store the disk (for using it with another machine with SATA connectors) and wait to find another working M/B from someone who had NS2 without disk (the opposite problem) or to find someone to repair the M/B (Lacie repair service? I dont think so)

So...
Just before leave it RIP, I thought I give it a last try with a different firmware. I noticed this post and I decided to give it a shot (without big hopes)...

...and guess what:

IT WORKED LIKE CHARM

It is not as user friendly as Lacie's, but it's fast, reliable and you can do whatever you want with this
