Data Volumes failed to Mount?!

So… I logged into my Web UI and blam red error telling me my data volumes have failed to mount? I have ssh enabled but im unsure on how to proceed. I would like to keep my data as it contains important pictures ie. Wedding and my sons birth and baby pictures. Im aware others have gotten this but I havent seen a solution yet. Thanks in advance. Fyi I already tried WD support and you know what they sent me here … -_^?

See my updated Guide below… Hopefully, I made it easier to follow

hello,

i am having the same issue as above can anyone help?

Step 1 ) First you need to turn on SSH in the MyBookLive dashboard. To do this go to your dashboard and in your address bar change the URL from

your mybooklive ip or name /UI/

to

your mybooklive ip or name /UI/ssh

Tick the enable SSH box

Step 2) If you are on a MAC login using Terminal app included with OSX

Open Terminal and type

ssh root@mybooklive.local

OR

ssh root@youmybooklive’s ip address

OR

ssh root@your mybooklive’s network name.local

and then hit enter and when asked, enter welc0me for the password

If you are a Windows user, download PuTTY from http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe

Enter the MyBookLive IP or Network device name in the window, port 22, tick SSH and click open

Now we need to enter the login information
type root for the username and hit enter
type welc0me for the password and hit enter
(The password text won’t show up in the PuTTY window)

Step 3) Now type the following at the command prompt

fsck /dev/sda4

The process should go through 5 passes and you will be prompted to fix things with a simple y or n

Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information

This should fix your filesystem on the datavolume. If it repairs everything successfully, type this at the command prompt

reboot

 Your MyBookLive should reboot and mount the datavolume

DONE!


Following the guide linked below could lead to complete data loss. If the data is irreplaceable, I would recommend trying a data recovery service instead.

If you get an error that the superblock is invalid and has a bad magic number when you run the  fsck /dev/sda4 command reference this guide

Same problem here…

@aleksanderturk Your data partition 4 is marked as raid as well as your swap partition 3 which is not normal and is probably causing your issues.

This is normal for a MBLDUO but NOT for the single drive MBL.

Off the top of my head, I’m not sure how to fix it.

@ nfodiz … My device is DUO …Mybook Live DUO.

Ah that makes sense then :slight_smile: Try posting your question in the MBLDUO thread

http://community.wdc.com/t5/My-Book-Live-Duo/bd-p/mbl_duo

I would try to help you in here but I don’t own the DUO and I don’t want to mess your drive up anymore than it already is.

The MBLDUO DataVolume is raid which is a whole different beast for me to learn.

You may also wanna try WD support

http://support.wdc.com/contact/index.asp?lang=en

You will probably get a quicker answer by phone

Good luck

Hi: yet another eager user who has lost access to mybook files.

I’ve been working through your instructions and after fsck/dev/sda4 my checksums were invalid so I clicked y to fix and now it comes up with a specific reference error. Is there any risk in fixing this: --see below

MyBookLive:~# fsck /dev/sda4

fsck from util-linux-ng 2.17.2

e2fsck 1.41.12 (17-May-2010)

One or more block group descriptor checksums are invalid.  Fix? yes

Group descriptor 0 checksum is invalid.  FIXED.

/dev/sda4 contains a file system with errors, check forced.

Pass 1: Checking inodes, blocks, and sizes

Pass 2: Checking directory structure

Entry ‘iTunes Library.itl’ in /shares/SmartWare/WD SmartWare.swstor/DAVID-PC/Volume.b0883aaf.4435.11e0.8530.806e6f6e6963/Users/David/Music/iTunes (13581410) references inode 13653406 found in group 209’s unused inodes area.

Fix?

Thanks for your help: kudos definitely on its way.

Do you have a backup of all fles in your Smartware backup folder? If you do I would say go for it

Actually - no, except that the original files are nearly all on the host computer.

Anyway, I’ve gone for it and the Public share has mounted!!

Yet to test the rest - can I get into the UI etc. but looking good and feeling much better than I have for the last two weeks.

Thanks

Wooohooo! Please keep us updated :slight_smile:

Hi,

It seems that I have got a slight problem. I do not have the fsck command on my WD box ?!?!?!

After the command p, I have got the following:

Could someone help please?

I am not LINUX savy at all. I thought about using mkfs to set 4 up to ext4, but …

I have done some further investigation, and I have got the following:

/ # e2fsck /dev/sda1
e2fsck 1.38 (30-Jun-2005)
/dev/sda1: recovering journal
/dev/sda1 has gone 1297 days without being checked, check forced.

Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts

/dev/sda1: ***** FILE SYSTEM WAS MODIFIED *****
/dev/sda1: 2683/122640 files (1.8% non-contiguous), 43929/489968 blocks

e2fsck 1.38 (30-Jun-2005)
Couldn’t find ext2 superblock, trying backup blocks…
e2fsck: while trying to open /dev/sda2

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193

/ # e2fsck /dev/sda3
e2fsck 1.38 (30-Jun-2005)

Not sure if this could help…

Hi

I am having a very similar problem. A few weeks ago my MBL began to restart every now and then with no reason at all. Finally yesterday I was unable to access my data and the device seems to be intermitent. A couple of times I have seen the message that the drive was not accesible and unable to mount.

I managed to update to the latest firmware from the dashboard but it seems things are even worse. I tried to execute the procedure described here but it requires the drive to be unmounted, and when the drive is unmounted I cannot access anything not by ssh or web interface.

I will appreciate any insight

Regards

Alberto
