[SOLVED] My Dilemma - Mounting A External Ext3 Formatted h/d

[viperd]

Afternoon all,

I have racked my brains and spent an age on this and I literally can't find a solution which I can follow so I thought I'd come to the experts. My problem 'seems' simple to solve, but has yet to work out that way, if anyone can help... I'd be eternally grateful!

My problem:
I 'had' a WesternDigital NAS, Raid1, dual 500GB, it failed, one of the drives I think (no diagnostic tools to tell me).
WD replaced my drive, however they 'upgraded' me as my product line was discontinued, so I now have a WD dual 1TB drive.
Obviously this leaves me with the useful dilemma of not being able to just pop my 'working' drive back into a Raid array and have it rebuild, so I need to get the data back.

What I have to work with:
Now I found out, through exciting means, that WD format their NAS raid array drives with Linux and my two 500Gb h/d's are formatted with EXT3.
I have my SATA drive out of the WD NAS and plugged into a ("Sharkoon QuickPort Combo" - you can see it in Amazon using that search) 3.5"USB h/d docking station and my windows workstations see the drive no problems.
Yes, you heard right, I am not a Linux o/s user and only have Windows (bleeeurgh, yes please don't kill me) o/s (XP/ Vista). However I have VMWare of Linux installed on my Vista workstation with Ubuntu, Fedora and DSL seemingly running without any problems and all the o/s see the USB drive (from what I can tell).

What I've tried
I have used DiskInternals within the Windows OS to extract 'some' data from my drives, but most annoyingly the data that has taken me the longest to build up (i.e. my TV series' and my films) are not available in this program (and believe me, I've left the drives to 'scan' file structure with this program for 12-16hrs at a time on probably a dozen seperate occasions and I still can't see the data!!
I've tried and failed to use KNOPPIX in VMWare mode (not in bootable CD - as I didn't see the difference) and whilst I got it working I couldn't see any way to get the data

Can you tell me...
How do I mount the drive within any of the above Linux o/s (or any other I can DL in ISO format and run in VMWare) so I can extract the data from it.
I can open terminal and scan the drive etc but as for finding the actual data in order to copy the files... I'm TOTALLY baffled to say the least!



REALLLLLLY appreciate any help anyone can give!!

Actually, I wouldnt go the way via virtualization.

1) Get a Knoppix ISO and either
a) burn it as a bootable CD
b) use UNetbootin - Homepage and Downloads to create a bootable USB stick
The goal here is to boot a linux natively.

2) Setup your new 1TB WD NAS to the point where it is useable.
aka CIFS and/or NFS should work.
A gigabit network between your PC and the NAS would be good,
but 100MBit/s should also suffice

3) connect your 500GB drive to that sharkoon device

4) boot your PC from CD or USB stick

5) Some information gathering / setup steps
a) open a console, become root

sudo su -

b) create a mountpoint for the NAS and mount it

mkdir /mnt/nas
mount -t cifs -o username=<USERNAME> //<IP_OF_NAS>/<SHARE /mnt/nas

c) see if and how the 500GByte disc is recognized

fdisk -l
dmesg

Please post the output of 5c) here and *please* use the code tags of the forum to do so.

Thanks for the response Irithori. I'll get on that now.

[viperd]

Right. Well that went smoother than I expected.
(TBF, I actually never saw that KNOPPIX o/s like that without the USB boot, so clearly I wasn't doing that correctly!)

Anyway, as advised, booted, mounted my nas on the directory creation and saved the file out. Details with [ code] tags as requested below...

knoppix@Microknoppix:~$ sudo su
root@Microknoppix:/home/knoppix# mkdir /mnt/nas
root@Microknoppix:/home/knoppix# mount -t cifs -o username=v1per //192.168.1.1/data /mnt/nas

I can see three issues:

1) You do have a intel gigabit NIC, but the speed is only 100MBit/s.
Presumably, because your switch is not gigabit?

[   83.897418] e1000e: eth0 NIC Link is Up 100 Mbps Full Duplex, Flow Control: RX/TX
[   83.897422] 0000:00:19.0: eth0: 10/100 speed: disabling TSO
[   83.897592] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

This is not a problem in itself, but the file sync will take longer.
I would expect 5-6MByte/s, while CIFS over gigabit with consumer hardware usually reaches something like 30MByte/s

2) The CIFS mount did not succeed

[  543.405932] Status code returned 0xc000006d NT_STATUS_LOGON_FAILURE
[  543.405937]  CIFS VFS: Send error in SessSetup = -13
[  543.405943]  CIFS VFS: cifs_mount failed w/return code = -13

Easiest case: You just mistyped your password.
If it worked, then /mnt/nas should show up after you type

mount

Also, the following should show the directoy listing of the CIFShare

ls -la /mnt/nas/

To start troubleshooting:
Can you

ping 192.168.1.1

and that username does have a 1 on purpose? v1per


3) The 500GByte disc can be seen. Good.
The biggest partition on it is sdc4.
But strangely, its partitiontype is ntfs. It should be "linux raid autodetect", like the other ones.
Hopefully no data got corrupted while you were using the DiskInternal tools..

So, *usually* this should give you access

mkdir /mnt/usbdrive
mount -t ext3 /dev/sdc4 /mnt/usbdrive
ls -la /mnt/usbdrive

If not, try to mount without giving the filesystem type (ie: omitting -t ext3)
or (but that would be strange) by using -t ntfs

Hi Irithori,

Thanks for your help with this.
TBH, I have no immediate problems with latency to the NAS as KNOPPIX also seems to see the local drive partitions on the machine the USB is running on so I can always copy the data there if needed.

To answer your questions tho, I can ping the NAS and the "1" was intentional yes. It's mapped ok second time around as /mnt/nas no problem at all.

I have to say I agree with you on the confusion re: NTFS/ Ext3. For starters I know it's not NTFS because a) DiskInternals reads it as Ext3, b) the native Windows o/s on my machine asks me to format it as soon as the USB dock powers up and it's listed in Windows' 'Disk Manager' as not an NTFS partition. So I'm not sure really??
For me this is where the problems start because, I haven't a clue how Western Digital create their Raid Array (this is only 1 of the 2 500Gb drives in the 'dead' NAS' mirrored Raid1).

I tried as you suggested to mount as 'Ext3' and as 'NTFS' and I got the below answers.
I guess I should try the same with the 'other' 500Gb drive in tho I have to say I am not hopeful.

Can you shed any light on the errors below??

knoppix@Microknoppix:~$ sudo su
root@Microknoppix:/home/knoppix# mkdir /mnt/usbdrive
root@Microknoppix:/home/knoppix# mount -t ext3 /dev/sdc4 /mnt/usbdrive
mount: wrong fs type, bad option, bad superblock on /dev/sdc4,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

root@Microknoppix:/home/knoppix# mount -t ntfs /dev/sdc4 /mnt/usbdrive
NTFS signature is missing.
Failed to mount '/dev/sdc4': Invalid argument
The device '/dev/sdc4' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
root@Microknoppix:/home/knoppix# 

[Irithori]

The errors mean, that neither the ntfs kernel code, nor the ext3 filesystem kernel code can make sense of that partition.
Ntfs was expected.
But ext3 is bad, as this was/is the filesystem used, according to your information.

You could try ext4

mount -t ext4 /dev/sdc4 /mnt/usbdrive

or let linux try to figure it out

mount /dev/sdc4 /mnt/usbdrive

You might also go through the exercise with the other 500GB disc.
- Unplug the usb device,
- exchange the discs
- plug the usb device back in
- fdisk -l
- mount...

But all information up to now rather point to a damaged partition/filesystem.
One broken raiddisc usually does not cause that kind of damage.
To be honest, it points to the restore attempts afterwards. Sorry.

If that it is case, you have two choices:
a) try to recover yourself
TestDisk - CGSecurity
PhotoRec - CGSecurity
b) ship the discs to a professional restore service

Interesting news Irithori, please let me know your thoughts.

Upon plugging in the 'other' 500GB h/d, I can now see that the fdisk -l command now gives the amended line:

/dev/sdc4             506       60801   484327588+  fd  Linux raid autodetect

When I saw this, I tried again to mount this using the previous commands and bingo, that worked!

I can now see the drive structure within my KNOPPIX 'explorer' window. Which is definitely further than I've got before.

(p.s. - at this point could you please give me the commands for 'dismount' and 'deldir' as the 'explorer' does look a bit messy atm!)

Now I have the 'new' problem that, when I try to open a share within the data structure that was permissioned previously I get a "Error - premission denied".

I kinda understand that, I assume it means that because I just did a 'standard' mount command without a [username] or [password] (like I did with my 'new' NAS) the old one is only letting me into the 'public' folders that were the drive. I can see the others but I can't browse them.
Ok, that makes sense.

Pls can you give me the command to enter a 'username and password' when I mount, so I can mount the drive with the right account which will, I hope!, let me browse the rest of my data...??!

[Irithori]

Just a thought:
As the other disc just workd(tm): Maybe you mixed them up?

Anyway:
you can use
umount /mnt/usbdrive
to (surprise) unmount.

And
rm -rf <DIRECTORY>
to delete directories.
Needles to say that the last one is to be used with caution.

As for the permission problem:
The knoppix user is not the user that was used on the NAS, hence no access.

A easy way would be to stay on the comandline and copy/rsync with the root user.

You can use

cp -r /mnt/usbdrive/* <DESTINATIONDIR>

But this might be a better approach:

rsync -r /mnt/usbdrive/* <DESTINATIONDIR>

Note:
- It doesnt really matter, where <DESTINATIONDIR> is. Local disc or new NAS doesnt matter, it just needs to be mounted.
- Both commands will take a long time.
You can watch the progress:
Open another console and type

vmstat 1

Look for bi and bo (block in, block out)
I would expect to see about 30MByte/s from the usb drive.

[Irithori]

While the machine is busy copying, you might want to open yet another console and do

man rsync
man cp
man vmstat
man mount
man mount.cifs

to learn, what the h*** you are doing just now

You can quit the man pages with q.
Search with /
