Lacie 5Big2 Failed After Firmware Update

[fvdw]

the funny thing is that the output of cat /proc/partitions doesn't match with these numbers

Later this evening I will set up my 5big2 and what output it gives with two disk, I don't have more available on this moment
First need to take care of some visitors, sorry to keep you waiting.

We'll have to re-create the array. For safety I'd like to backup the start and end of all partitions. Can you connect an usb disk to save the data?

[unlucky1]

I can connect a usb (I have a 3 Tb one I bought for just in case we were successful!) but I have no idea how to copy the data off of it to the external disk. I just plugged it into the top USB port of the lacie and it's ready to go.

Well, you can try to mount it. Have a look in /proc/partitions which devicenode it has, I suppose /dev/sdf1.

Code: Select all

mkdir /tmp/mountpoint
mount /dev/sdf1 /tmp/mountpoint

[unlucky1]

It's not sdf1. And I made /mountpoint since I have no /tmp (it failed). If it's sef1, it fails.

Code: Select all

root@(none):/ # cat /proc/partitions
major minor  #blocks  name

  31        0        500 mtdblock0
  31        1          4 mtdblock1

root@(none):/ # mount /dev/sef1 /mountpoint

Hi unlucky1,

with the lacie big, usb drives have as name se*. So you need to use sef1 instead of sdf1

And you made a misstake in the mountpath : /tmp/mountpoint in the mount command.

[unlucky1]

But mounting it failed.

Code: Select all

root@(none):/ # mount /dev/sef1 /mountpoint
mount: mounting /dev/sef1 on /mountpoint failed: No such file or directory
root@(none):/ # mount /dev/sef /mountpoint
mount: mounting /dev/sef on /mountpoint failed: No such file or directory


[Mijzelf]

sef1? Lacie...

You can create the device node:

Code: Select all

mknod -m 666 /dev/sef1 b 8 81

This is generic, BTW. It is possible to create a simple script which read /proc/partitions to populate /dev. The major, minor and suggested device name are listed.

[unlucky1]

Code: Select all

root@(none):/ # mount /dev/sef1 /mountpoint
mount: mounting /dev/sef1 on /mountpoint failed: Invalid argument

@unlucky1
Note : I edited my post : you didn't use the right mount path
I read too quickly your post about the folder /tmp :pound
