I refer to my post on http://forum.nas-central.org/viewtopic.php?f=263&t=17165.

In the end I was able to get fvdw-sl console and telnet working, but I do not know how to proceed, fix the RAID and copy data from my Lacie. Data is vital to us!

If someone can help me I really appreciate it.

Kind regards,

Frank

Hi pacco,

if I remember well, the patch to handle the custom Lacie device node is included in the last standalone kernel version (@fvdw can you confirm this).

So you should not need to update the block node. To check this do

Code: Select all: ls -l /dev/sd[abcde]*

and read /proc/partitions

First step, is to check your partition table for all disks and in 2d step to check the raid device (you need to upload the static mdadm binary)

So post the content of /proc/partitions and the gdisk output for sd[abcde]

I am not quite sure about the commands to use, but maybe this list is helpful?

So the devnode are not update in /dev :

Code: Select all: brw-rw---- 1 root root 8, 0 May 3 11:01 /dev/sda

whereas in partitions you have

Code: Select all: 8 32 976762584 sda

so minor 32.

You should have udevstart, so try to run it. If it is missing you find it here viewtopic.php?f=26&t=1412&p=9753&hilit=udevstart#p9755 and you need to upload it with tftp.

It seems that you have a faulty disk sde2 (or sdd2 with the update issue). So the 5th disk (counted from left to right when you see the back side: slots)

So first do udevstart and post again the output

mdadm --examine sd[abcde]2
ls -l /dev/sd[abcde]*
cat /proc/partitions

Later you should run e2fsck to check the real faulty disk

Tried to unzip udevstart from the link provided, but I get a message the zip is corrupt :-(

by **Jocko** » Mon May 18, 2015 2:34 pm

Indeed, in the past we have an issue with the attached file. I go to try to find it otherwise you need to wait fvdw who have the source file

by **Jocko** » Mon May 18, 2015 2:50 pm

Sorry, but I don't find udevstart but you can use Mijzelf script :
(udevstart script is now available here: viewtopic.php?f=7&t=1271&p=18801#p18801)

upload the file, set run permissions

Code: Select all: chmod 755 yourfilename

and run it

Code: Select all: ./yourfilename

With the command mdadm --assemble /dev/md0 /dev/sd[abce]2 --run (thanks to Mijzelf on nas-central.org) I was able to mount the RAID with 4 disks out of 5.
Now trying to transfer data out of the box to another NAS.
