Unable to mount array?

[jaysback]

Hi all.
My first post and only my second day using Linux (Ubuntu 10.10), so please be gentle with me. lol.
Bit of back ground to my problem.
I have a Netgear Stora that has just died, but realy need the info off the drive inside.
Support have told me that the drive can be read on Linux, so here I am.
Right.
Places-Computer shows drive as "array".
System-Administrator-Disk utility gives me everything blank apart from State : not running, not enough componets to start.
Now there is a button under this "Start Array".
Can I simply just click this or is there more to it than that as I don't want to lose anything on the drive.
Thanks in advance.

From a terminal post the output of:

sudo fdisk -l

(that's a little L)

Hi barriehie.

Hope this sheds some light on it for you.

Hmm, search engine results tell me that's a proprietary 'box' you've got their! Since the manual indicates a section on failed drives I'ld stay away from it! Sorry!

[jaysback]

DOH!
Thats not good
So much for Netgear's customer support.
Cheers for taking a look though.

I have just tried mdadm.
This so far hasn't worked

[jaysback]

Things are looking up
I can now see all the folders in the drive
I don't have access to them due to permissions

[jaysback]

Permission problem sorted and stuff of the drive.
Had to set a password for the root login and then was all good.
Cheers all for your help

I am also a Linux newbie... I had a buffalo terrastation die on me I believe I over filled the RAID and when I lost power I did not have room to load the needed files how it did not get a chance to delete them before the power was lost.

I found this article
buffalo.nas-central.org/wiki/Terastation_Data_Recovery

So I borrowed a Intel PowerPC Mac Mini from a friend and got adapters and a USB hub to plug the drives into the Mac Mini. I made a Ubuntu 10.10 disk and booted into it and it see's the array but can not mount it.

I figured out how to enable root and logged into it and tried to run the steps but still no luck.

I did a sudo fdisk -l with the following results:

I noticed the mention of mdadm i downloaded it but could not figure how to install it. I was not sure if I had to have a true install of Ubuntu and not just boot off the CD. When I unzip the folder there is a install file that when I double click it tells me: To build mdadm, simply run: make to install, run make installs root. No configuration is necessary.


Please help MUST get some files off the RAID
