OK, here is the latest. When i go into the terminal window i still get the message:

mount: /dev/sdb2 already mounted or /mnt/xfs busy

I still can not see the drive. There is nothing in the /mnt/xfs folder. I feel so stupid, like I am doing something wrong. I hope I am not frustrating you. Any more ideas?
 
You shouldn't feel stupid its certainly not your fault!

In fact, its the md driver that is attaching your drive without your permission, that's a violation of a user's authority in my opinion, and thus a bug. But.. that's rather philosophical. :)

Try this:
1) first go to synaptic again (System->Administration->Synaptic) and install the "mdadm" package if not already installed. This is to administer md-arrays or software RAID arrays. md is the kernel raid driver while mdadm is the utility to configure/control it.

2) gather some information just in case, can't hurt, and paste it in this thread:
mount
dmesg | grep -i md
sudo fdisk -l
ls -l /dev/md*
sudo mdadm --detail /dev/md0

3) this is the actual trick, and should stop your RAID array, may not work if the /dev/md0 device not exist, in that case the above information should help me find the right command, but it 'should' work:
sudo mdadm --stop /dev/md0

4) mount your volume:
sudo mount -t xfs -r /dev/sdb2 /mnt/xfs

If it still doesn't work -- don't give up! At least i won't since it should work this is just a minor annoyance -- it should work! The md-driver being so intrusive is annoying though. 😛

If it did work: hurray! I don't need the information in step 2) only if its still not working. In that case i'll bring my shotgun and emasculate(*) the md driver myself. 😀

Hi,

I have the same issue with Western Digital's WD My World Book II (1TB - RAID: 2x 500GB).

The command:

sudo mount -t xfs -r /dev/sdb4 /mnt/xfs

Returns:

mount: /dev/sdb4 already mounted or /mnt/xfs busy

It doesn't seem to show in "Places > Home Folder".

Any help would be awesome!
 
I had the same problem with my Lacie drive. 1 TB 2Big. Drives were mirrored , drives were good , enclosure bad. I found a software solution. UFSEXPLORER.COM. The software and a USB external hard drive adapter did the trick. actually pretty simple. Even better when you can find the software online. You know what sites I mean. Free.
 
Hi,

I did not read the whole thread, but having the same problem I found an "easy" solution:
1. get an old PC where you can put in a hard drive to be formatted later. That can be some old drive with only a couple of GB, Linux doesn't need much.
2. get the Knoppix Live CD here :http://www.knoppix.net/
this is a live CD that allows you to copy a working Linux on your PC without any hassle.
3. put one of the LaCie Raid disks into a USB enclosure and connect it to the PC
4. start up the PC with the newly installed linux
5. go to the shell (before mounting the graphical interface) and type exactly "sudo mdadm --assemble --run /dev/md0 /dev/sdb2"
sdb2 is your RAID, mdadm mounts the RAID
6. exit the shell and load the graphical interface
7. The RAID appears in your linux file manager and can be copied wherever you want!

Enjoy
 
pschlief: that's a nice method, thanks for sharing.

It appeared to me that jbeigh was very close to recovering his data (would be a shame if he didn't - after all trouble). The only thing that didn't work in the end was mounting the XFS volume from a separate physical disk. This is likely because the disk is part of a RAID-array, and the /dev/md0 device is created.

I am curious however, it should have just worked:
1. install xfsprogs as it uses the XFS filesystem
2. check with Partition Editor (System->Administration->GParted)
3. try to mount, click Places->Home; then click ".. GB Filesystem" on the left.

Anyone who still needs help with this; if the tips in this thread do not help; please post all your data and i'll have a look. :)

I tried this, but when I enter the shell command, I get "Has No Superblock, assembly aborted" Can you guide me past that?
 
Hey Sub Mesa, I tried the command:

4) mount your volume:
sudo mount -t xfs -r /dev/sdb2 /mnt/xfs

I got back that the mount point doesn't exist. Can I create it? If that's the only thing stopping me, then I'll be in good shape.
Thanks!
 
Thank you sir! That worked, but now it's telling me that the special device doesn't exist... such a deep rabbit hole.
 
Are you sure you are running XFS? That is not a filesystem you can have available in Windows.

You can mount on /mnt or just create another directory you wish:

sudo mkdir /blabla
sudo mount -t xfs -r /dev/sdb2 /blabla

Then your files should be in the root directory /blabla
 
I did try that, but it didn't like it. I was actually using Ubuntu, and then tried Knoppix. No dice on that, but I ended up getting tired of fighting it and purchased the UFS Explorer program. I just connected the drive up to windows xp, ran the program and it was like butter. About $50, but sometimes the money is worth it. Like in this case. :) Thanks for the replies though.

Hello from Italy (Mac os x user).
I try to resume my case (sorry if it is too long)
I own a Lacie 2 Big 1,5 TB using it in safe mode 750 GB.
Well some time ago i realized that one disk was out of order. I don't know when it went out of order because the NAS continued to work regularly (only with some clicks from the damaged unit).
I decided to stop it waiting to buy a replacement disk.
I couldnt find the same disk so i tried to put a Barracuda 1TB (not from LACIE) but the NAS unit didn't recognize it but continued to work regularly.
So i to turned off the NAS waiting to buy a USB2 external disk for backup purpose (i decided to trash the NAS after the backup).
Today i powered up the NAS for the final backup but unpredictably it seems crazy or half dead so that i can't see it on the net (sometimes the front light blink red/blue, sometimes it doesn' light up, no way to see it on the network, the power off switch doesn't have any effect, etc).

I put that NAS drive into a USB enclosure and I checked the disk with the normal Leopard disk utilities.
I could see 7 partitions named:
disk4s2 (the biggest one 697 gigabytes)
then
disk4s5, 6, 7, 8, 9, 10
They are all defined as LINUX except the #5 defined LINUX-SWAP

I installed the PARAGON software (10 days try) and it succeeded to mount only 2 partitions while the biggest one remained unmounted.

Someone have similar experience?
On that (safe raid?) disk i stored all the photos of my life...

A friend of mine had similar experience with another LaCie unit. I guess that in the future i won't buy even a cable from them...

By the way... at the beginning of that NAS career i lost the AFP access.
The files were still present but downloading by SMB the files uloaded by AFP was a disaster because all the MAC resources on older files were lost making them simple "EXEC" icons unusable!

Thank you for your understanding.

Alberto...

I have the exact same thing with my LaCie 2Big Network unit with two 500GB drives in safe mode.
I got a blue / red blinking LED 2 days ago on the front LED and on the back LED related to one of the 2 drives.
the other drive had a solid blue LED.
red/blue blinking LED means that the drive is booting (or trying to boot)

The LaCie technical people were not optimistic when I contacted them and I got the same sales pitch "send your unit to a data recovery specialist" They believe that the drives might be corrupt thanks to RAID but that the Data should still be there...

they recommended to do the following:
The procedure below will reset the 2Big Network to factory settings:
IMPORTANT NOTE: Following the procedure below can ERASE ALL DATA on the drive. Prior to following these directions, verify important data is stored securely on a different storage device.
1 Switch the drive OFF. Once it has shut down, ensure the power switch remains in the OFF position.
2 If the drive is in the SAFE mode, move the RAID switch to the BIG mode.
3 PRESS AND HOLD the button on the front.
4 MOVE the power switch to the ON position. The light on the front of the drive will start blinking.
Once the light stops blinking, RELEASE the front button.
5 When released, it will begin BLINKING AGAIN.
6 When it stops, PRESS AND HOLD the front button. The light will begin to blink again.
7 When the light stops blinking, RELEASE the button.
The drive is now resetting itself. Switch the RAID selector back to SAFE if desired.
To restore data if it was lost during the process, recreate the shares and users on the unit prior to the reset. Any firmware updates applied will need to be applied again.

I did not yet do this because, like you... I do not have a backup for my data
I actually trusted that the LaCie in SAFE mode would PROTECT my data - after all... why use safe mode and only half of the drive's capacity when you can combine the 2 drives and have more storage space.. ARRRGH!

anyway, I have a friend who has the identical NAS and I would like to try to use his before trying to reset my box.
In my case, LaCIe believe that their hardware is defective and that it needs a reset... but the drives are a critical componenet to getting their hardware back in shape..

good luck with your setup... please do let us know how it goes
and I will report on my results in the coming days
this is hugely frustrating!
 
tbox...
i'm still working on.

I have a friend with the same identical NAS (we bought them the same day at the same shop).
I put my lonely disk into his NAS but... i got a faster blinking and no results.
That surprised me because i was sure that my disk could work into his NAS!

Double strange because my lonely disk surely worked for a month into my NAS before it went wrong.

Now i changed strategy so I put that drive into a USB adapter and installed UBUNTU and i can see the array on the desktop but it doesn't mount.

Since i am a mac user i tried to use File Salvage.app and it recovered almost 200.000 files correctly but.... the bad side is that the file weren't structured at all and they lost their name!
Imagine a folder containing 41.000 jpg files named "File00001.jpg" to "file41.000.jpg".
the same for DOC, PSD, MP3, etc etc.
It's better than nothing but if i can't recover the folder structure i will be able only to recover the photos while my backups of my CD-ROMs (i developed many cdroms) will be totally useless since a single cd rom contained lot of spare pct. doc. etc etc structured into their folders.
Fot the photos i used a little app that rebuilt the filename using the EXIF data so i could separate the files using their creation date. The file without exif data has been named with the current date :-((
I got some wrong date due to the camera that was wrongly set up (example 1970's date).

I tried a win software called R-studio and i could see SOME of the old disk structure but only a very little part.

UFFFFF
i'll continue hoping to find some magic exper user who will be able to help me to mount the disk with the original structure!

You say "hugely frustrating" ....
yes!
Think that a friend of mine lost data on a Lacie Raid too and i own a USB box that is giving me some problem: a lacie usb box.

Surely i won't buy anything from LACIE in the future!

Keep in touch

Alberto






 
OK... it's Sunday
and I decided to pick up the ball again and give it another shot.

I followed La Cie's RESET guidelines and made it all the way to step 4

THe LED on the front of the unit
never came on or even blinked... the La Cie machine is broken
and I believe that my drives are still OK

if I were to send this unit to the distributor, they would send it to LaCie
and they would surely delete all my Data

thus... WHAT TO DO?


My friend and I bought 2 of these crap units a few years ago
and I am hoping that when I get a hold of his unit, my data will be accessible.

I can always try to do a reset on his unit AFTER I BACKUP HIS DATA

sheesh... what a waste of time and energy!
 
hello tbox...
i worked with the unit of my friend but i didn't back up his data LOL...
Apparently no problem since all the username , partitions and other data are written on his disk.
Simply: HIS unit with my disk didn't work but when i re-inserted his disks into his unit then all worked perfectly.

(by the way: my friend recently lose the AFP protocol on that crap and after the firmware update he had huge roblems too).

As i told you i could perform a recovery of all the files with no root structure.
I was wondering if there is some recovery service able to recover the whole disk in the original form and i was wondering about the pricing for such services.

Are you informed about that?

I always hope that some Linux expert could read about our problem suggesting some magic procedure to restore the raid ...

keep in touch!
 
hi to all.
any update about that?
my device failed too and I had a RAID 0... is there a way to retrieve data?
I tried with a friend Lacie, same model, but i got same results as richter1956:
HIS unit with my disk didn't work but when i re-inserted his disks into his unit then all worked perfectly

please help me
 


Hi sub mesa
Thanks for all your work here! I too am having trouble with a lacie 2 big drive specifically accessing the data on the hard drive. I have removed the hard drive from the lacie box and pluged it directly into my motherboard via sata cable. I have downloaded the latest ubuntu OS and I am booting that from a USB memory key.

I have followed your post with alberto but have not had any luck accessing my drive. It is present in the system and as you can see below it is the sdc drive with?10 partitions. None are accessible to me. Not sure if the install error with mdadm is relevant or the fact that I could not create a md0 file (actually I really dont have any idea what that means either! lol).

I don't have any experience with ubuntu except for with my recent problem with data access to this drive. Looks like all the info points to umbutu and the mdadm program but I am really not sure where to go from here.

Any help would be greatly aprreciated!

I bought the drive to have a central space where if one drive went down I had a back up with the raid 1 configuration. little did I know that box failure leads to much sleepless research!

Thanks

Shane

So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
mount -a [-t|-O] ... : mount all stuff from /etc/fstab
mount device : mount device at the known place
mount directory : mount known device here
mount -t type dev dir : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
mount --bind olddir newdir
or move a subtree:
mount --move olddir newdir
One can change the type of mount containing the directory dir:
mount --make-shared dir
mount --make-slave dir
mount --make-private dir
mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
mount --make-rshared dir
mount --make-rslave dir
mount --make-rprivate dir
mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using -L label or by uuid, using -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say man 8 mount .

ubuntu@ubuntu:~$ sudo mount -t xfs -r /dev/sdb2/mnt/xfs
Usage: mount -V : print version
mount -h : print this help
mount : list mounted filesystems
mount -l : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
mount -a [-t|-O] ... : mount all stuff from /etc/fstab
mount device : mount device at the known place
mount directory : mount known device here
mount -t type dev dir : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
mount --bind olddir newdir
or move a subtree:
mount --move olddir newdir
One can change the type of mount containing the directory dir:
mount --make-shared dir
mount --make-slave dir
mount --make-private dir
mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
mount --make-rshared dir
mount --make-rslave dir
mount --make-rprivate dir
mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using -L label or by uuid, using -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say man 8 mount .

Hi, first of all sorry for my english.

Then, I have same problem and I solve it with this steps (not news, but it seems work):

1) $sudo nano /etc/fstab
add last line-> /dev/sdb2 /mnt/xfs xfs ro,user,noauto 0 errors=remount-ro 0 1

2) restart

3) $sudo mount
-> unmount all innecessary volumes, in my case:
$sudo umount /dev/md1

4)$ls -la /dev/md*
->for all md devices:
$sudo mdadm --stop /dev/md0
$sudo mdadm --stop /dev/md1
$sudo mdadm --stop /dev/md2
$sudo mdadm --stop /dev/md3
$sudo mdadm --stop /dev/md4

5)$ls -la /dev/md*
-> it must be empty

6) sudo mount -t xfs -r /dev/sdb2 /mnt/xfs

And it works! Good luck!
