Lost SDA

Gratstein 10 Feb 2011 11:13

Hi,

My MBLive is pretty messed up since the sda disapeared after a reboot.

Here is some commands for additionnal info :

MyBookLive:~# vi /etc/fstab

sysfs /sys sysfs defaults 0 0
tmpfs /tmp tmpfs rw,size=50M 0 0

/dev/md0 / ext3 defaults,noatime 0 0

I shouldn't have tried to manipulate with my data on it :S

Could someone help me, I know I can get my data back but the question is how!?

Thanks

Do

MyBookLive:/# cd ~
MyBookLive:~# wget http://ftp.us.debian.org/debian/pool/main/u/udev/udev_0.125-7+lenny3_powerpc.deb

MyBookLive:~# dpkg -i ./udev_0.125-7+lenny3_powerpc.deb 

MyBookLive:~# reboot

And be happy.

Still messy but I got all my data back in place.

I can't say how grateful I am.
And 'Merci' to all who gave me a hand.

data partition should be mounted as
/dev/sda4 on /DataVolume type ext4 (rw,noatime,nodelalloc)

Re: Lost SDA

Gratstein 13 Feb 2011 19:24

I can't find any sda4 in /dev directory. Should I edit the fstab and add a line for /dev/sda4 or should there be sda4 in the /dev directory before I try doing so?

Does any WDLive owner gets the same boot errors as me? I was thinking more of a driver issue.

Thanks

Re: Lost SDA

frodo837 14 Feb 2011 18:35

/dev/sda4 should be before
try type following in telnet

parted /dev/sda/ print

it should looks like this

Number  Start   End     Size    File system     Name     Flags
 3      15.7MB  528MB   513MB   linux-swap(v1)  primary

 2      2576MB  4624MB  2048MB  ext3            primary  raid
 4      4624MB  1000GB  996GB   ext4            primary

Re: Lost SDA

Gratstein 15 Feb 2011 15:48

Since there is no /dev/sda4, this command returns that there is not such files or directory.
I would like to check the boot options but I can't find the config file.

Beside I would like to be sure what's actually in place on the MBLive.
The root partition of 2 GB is stored on the same drive as the DataVolume? But mounted as md0 which is raid made of sda1 and sda2, ext3 file formated.

Also, I'm not sure that the problem comes with the moding of the system. It happened after I unplugged the power supply cause the system hanged.

I have found that the last Firmware fixes a possible disk boot failure. I can't upgrade via the WD webinterface, but can I, and may I upgrade from command line.

Thanks,

my /proc/partitions file :

major minor #blocks name

8 0 1953514584 sda
8 1 1999872 sda1
8 2 1999872 sda2
8 3 500736 sda3
8 4 1948998656 sda4
9 0 1999808 md0

Since there is no /dev/sda4

wait , i didn't mentioned sda4 just sda, you should have it, so please provide result of parted

Re: Lost SDA

Gratstein 17 Feb 2011 11:25

Re: Lost SDA

frodo837 17 Feb 2011 19:57

i couldn't understand how /dev/sda could be absent, especially if /dev/md0 raid based on sda1 sda2 that should be child of sda and that line present in your log

Feb 11 00:04:36 localhost kernel: sd 0:0:0:0: [sda] Attached SCSI disk

could you post results of

2. ll /dev | grep disk

I think that your sda4 is broken.

In the map /usr/local/sbin you can find de scripts for the admin-site.

maybe will help

/usr/local/sbin/createDataVolume.sh

greating,

Re: Lost SDA

Gratstein 19 Feb 2011 14:17

I think this script should run at boot time.
I have insserv installed, I don't know if it sould be there.
Also what files starting by . do you have in /etc
I have theses ones but maybe they should be more :

.eula_accepted .fw_update_alert .mionet_installed .mionet_started .pwd.lock

I'v been browsing around and reading scripts but I'm still lost. I don't want to take out the hdd of the box, but I may have to since I still don't have clues.
I think a firmware update could help me but the available space needed is 3GB :-S

EDIT : I used apt-get since the beginning, but I may have made a huge mistake by using aptitude once, I have this aptitude log :

When I read: http://packages.debian.org/sid/insserv then I think that you can use it for to chance the boot sequence.

Why you want to change that?

frodo837 23 Feb 2011 08:10

I think bad that udev was updated, you should somehow back to old version.

Re: Lost SDA

Gratstein 22 Feb 2011 11:29

Since insserv was not installed at the beginning, it could have changed the way the disk boots and mess with the wd scripts and config, and skip the mounting of sda4 and swap.

Re: Lost SDA

I have read back your forlast message .
You say " I think this script should run at boot time."
Now I see S15mountDataVolume I think you ment mountDataVolume runs in boot time and not "createDataVolume" ??

Re: [SOLVED] Lost SDA

Gratstein 26 Feb 2011 14:28

I got up this morning and my MBL was making this noise
The front LED is yellow and I can't access the drive. It seems down, it doesn't ping.
I'm thinking of a check of the filesystem. I have more than 1TB data so it may take a while, but it scares me anyway.
Downgrading Udev made my sda4 partition available, I copied files from my computer to the disk to free space. I did it with Winscp, the transfer was in progress but this morning the connection was lost and the transfer was uncompleted.

Re: [SOLVED] Lost SDA

bogie 19 Mar 2011 01:20

Hi

I have a very similar problem. I needed to move my MBL so unplugged it. I thought it was completely shutdown but it was not (but there was no disk activity). When I restarted, "DataVolume" was not mounted leaving me with the exact same symptoms as Gratstein throughout this thread.

I followed Libfun's post and installed udev. When I rebooted the MBL had a yellow light, terminating in a red light. I cannot SSH in anylonger.

At the moment I would like to get it back to the state before I ran wget and dpkg. If I connect the MBL disk to a PC running linux, is there anything I can do to reverse what I have done ?

I invested a lot of time modifying the machine and I dont want to lose the changes. I have a backup of the data that was on the disk (sda4) - so less important.

thanks for any help.
