OpenSUSE Install :: Error Message Was 'bad Magic Number, Corrupt Superblock' With A Suggested Command To Try Another Superblock?

May 14, 2011

After several crashes during videos it seemed like a good idea to fsck root. Downloaded the latest systemrescuecd and ran it at boot. The error message was 'bad magic number, corrupt superblock' with a suggested command to try another superblock. That failed with the same message. Tried tune2fs to force fsck at boot and got the same message. The drive is less than 6 months old and the installed system is working more or less ok. The command I used was 'fsck.ext4 /dev/sdc2'. What am I doing wrong?

Server :: Mounting Drive Bad Superblock Error Wrong Fs Type, Bad Option, Bad Superblock On /dev/sda1?

Jun 16, 2010

I have a x64 OpenSUSE server with two hard drivers installed. The first one is used for the / and /home partitions and the other is for backups. Ironically enough it is the backup hard drive I am having trouble with. I was having trouble writting to the drive and unmounted it to preform a fchsk, however now when ever I try to mount it I get the following error:

mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Does anyone know who I can repair the drive and retrive data?

General :: Cramfsck: Superblock Magic Not Found (Scientific)?

Jan 2, 2010

I have come across a problem on my Scientific Linux, I have searched the forum but couldn't find what I am looking for, so I decided to post my question here.well, here what I did: under the Terminal I got Cramfs-1.1.tar.gz installed, and then i used the "make" command to build the cramfsck and mkcramfs and it was all now I have an image I called it "backup.img", and I tried following command:./cramfsck -x ./output backup.imgbut unfortunetly I got the following message:./cramfsck: superblock magic not foundSo I kept on thinking what is this Superblock magic thingy? I did a google search but I kind of got lost and didn't end up finding anything useful, but I am just thinking it could be some kind of package which I need to install? I tried the following command:apt-get install magicbut it seems there is not such package exists with that name.

OpenSUSE Install :: Bootup Superblock Issue Related To /dev/disk/?

Jul 23, 2010

I decided I needed to expand my openSUSE partition because I was running out of room. There was some unallocated space following my /home and swap partitions that I wanted to assign to my / partition.

So after taking note that bad things could happen (as I've read everywhere), I got myself a copy of GParted (since Yast! partitioner doesn't move partitions, does it?) to start getting the thing to work. Well, actually, I got PartedMagic which has GParted (I realize it could be a problem NOW if they didn't have the latest version).

So the first step was to move the swap partition. I decided to do it one step at a time and only moved the swap partition to the end. That turned out problems whatsoever.

The next step is where the problem came in. It was moving the /home partition. It took a while to move but once it got to the end, it showed a message that was similar in nature to "error detected" without giving a long list of error messages. If it did, I probably would have copied it down. There wasn't anything in the "logs" either in GParted besides what it showed. Looking back, I probably should've went into /vars/logs to get additional log information but I guess I wasn't smart enough to do so (provided that GParted does leave log messages there which I think it does).

After that, it refreshed the drive and it ended up showing no partitions with an error and saying the only thing it can do is create a new partition table. After that, openSUSE wouldn't boot. After loading, (both normal and failsafe modes) it gives me the message in the link at the bottom. I can still access those partitions fine. Nothing's corrupted. Windows also boots up fine (it's on a different drive though) and reads the affected drive fine. Linux-based LiveCDs (including openSUSE 11.3) reads the partitions fine too.

I've tried using e2fsck on my ext4 partitions with commands I found during a search and they seemed to "fix" those partitions but it still won't boot and gives me the same message. Looking at it carefully, it seems the reason it can't find a superblock is because it can't find part8 of whatever that thing under /dev/disk/by-id/ is.

I would very much prefer a failsafe (or at least mostly failsafe) solution that won't (or is unlikely) to result in requiring the restoration of a backup but I do understand that there is always the chance of something going wrong that will kill everything. Considering that I can still access the data on that drive, I don't believe the data is corrupted. Maybe the drive itself (as in whatever signatures it may leave) but not the filesystems.

This is what I end up with trying to boot into openSUSE (sorry, I don't know how to get the log when it doesn't put it in logs directory:

Ubuntu :: How To Fix Filesystem / Superblock Error

Mar 7, 2010

Running ubuntu server (ie no gui) but suspect this might be a general problem.

With the machine booted from the hard drive, if I run fdisk -l I get an invalid partition table message code...

Unable to read the contents of this file system!
Because of this some operations may be unavailable.

How do I correct this error?

Ubuntu Installation :: Superblock Error In Gparted - Can't Run Dumbe2fs - E2fsck

Mar 8, 2011

I have Ubuntu 10.10 installed (installed xubuntu on top and that is what I run but should not be an issue) on a laptop and it runs fine but I am giving it to my daughter so I wanted to install windows as well, and dual boot, so she could play a couple of games that she has. When I booted with gparted cd it shows the information icon beside my partition (have 2 one swap sda1 and one for ubuntu sda2) and everything I attempt to do tells me the superblock and all backups are bad. I am not sure how this can be since the system boots and runs fine.

In gparted I can't run dumbe2fs or e2fsck without getting the error but when I do dumpe2fs in the system it seems fine. I am pretty sure I used ext2 or ext3 as a filesytem as it is an older laptop so ext2 is what I usually run with. Maybe I just let ubuntu install whatever it wanted this time, I can't remember for sure which I chose during this install. have been backing up all the data to move it off anyway so reinstalling won't be a big issue. I had checked out how to reinstall grub2 after doing the windows install so thought I was all prepared but apparently I was not that prepared.

Ubuntu Installation :: Reboot After Update - Invalid Magic Number Error

Jan 7, 2010

This has to be the sixth time I am going to have to reinstall Ubuntu (Can't get enough of that Linux greatness) in the past 6 months. I just don't understand what exactly is wrong, I don't install anything extra (but the ubuntu restricted extras) yet updates that ask me to reboot will take me to a GRUB command line screen and trying to boot through the command line interface gives me an, "Invalid Magic Number", error.

There should be an official tool for when problems like this come up, so that users like me can easily move their files off their HDD before reinstalling. I didn't come here to rant but, does anyone know what may be causing this everytime, how it can be avoided maybe even how to deal with the Magic Number error and boot in (I wouldn't mind typing in the commands every time BTW)?

Ubuntu Servers :: Bad Superblock /dev/md0 Softraid 10.04?

Mar 24, 2011

This might take a little while to explain so please bear with me. I just bought a HP N36L microserver to replace my Netgear ReadyNAS as it has 4 bays as opposed to the 2 in the Netgear, the HP came with a 250GB Seagate drive in so I installed Ubuntu 10.04 server onto that as a minimal install in a 5GB partition, selected basic server, lamp and samba during the setup and then once installed added the minimal gui, all good so far.

The idea was to have 3 1TB drives in the HP running software Raid 5 and after trying to do this via the disk utility gui and having misaligned cylinders I found this guide for setting up the Raid 5 array - Now the problem with setting up the raid was I had just over 900GB of data on the 2 disks in the Netgear and not enough space anywhere to back it all up so the plan was to install 1 x 1TB drive and format to ext4 and transfer all the data onto it from the Netgear, then pull the 2 drives from the Netgear and build the Raid 5 array using just those 2, then copy the data from the 3rd drive onto the raid and then add the 3rd drive and grow the array.

This actually was all going fine, 2 disk array was built, data transferred and all was good so added the 3rd drive to the array and issued the grow command, after many hours this completed and I had a 2.0TB filesystem icon on the desktop.

Now the problem, the last two steps were to unmount the array and run an fsck on it (as per the guide) and then grow the filesystem but the array wouldn't unmount it kept saying it was busy, I tried to force it but still nothing so I decided to reboot (my windows background coming back to haunt me perhaps) when the box came back up it failed to mount the array due to a bad superblock

Debian :: Can't Read Superblock - Resolve This?

Apr 11, 2010

I removed a hard drive from a failed Buffalo LinkStation NAS. The drive was 1TB and formatted in XFS. I installed Debian Linux on my Mac using Virtual Box just so I could get to the files.

When plugin the drive (via USB) two volumes show up, but there's another that I can't seem to open (and may have all of the shared files I need). It's the largest volume (over 900 MB).

I keep reading to run xfs_repair, but when I type that in the terminal, I am given "command not found". I am not sure how to use it.

Also when I try to open the volume I am given "can't open superblock" error.

I am not too familiar with using Linux and ma just trying to get to my files.

Slackware :: CD Rom Not Mounting - Can't Read Superblock / Fix It?

May 10, 2010

I am newer to Slackware but not to Linux. I am having the hardest time trying to get my CDROM to mount for me so that I can play audio cd;s and the like. I can see that the system knows that my CDROM drive is there and that it works because I installed Slackware 13 from my CDROM drive as /dev/hdc. Now when I put in a cd nothing happens? I have googled away and searched this forum quite a bit before posting this but I have tried almost everything I can think of and what others have mentioned. I have screenshots to show you what I mean. When I try to run the command:
mount /dev/cdrom /mnt/cdrom
I get it as mounting as read only and it says can't read superblock? Now that is fro my slave IDE CDROM on top as hdd. I have tried before to mount it as /dev/hdc but to no avail. I know both CD drives work just fine because I used them to install the system. I am going to put the screenshots below so maybe someone can help me! Also I can eject the top CD drive with the command code...

Debian :: USB Drive Corrupted - Cannot Read Superblock

Mar 16, 2011

I have a removable USB pen drive, that all of a sudden, when it got 99% used, stopped working. When I try to mount it (manually) I get "can't read superblock". I know there is a ton about this on Google and I've read a lot of them, but most seem to be about formatting a drive, or fiddling in fstab. I'm trying to run fsck on it, and it finds errors, (among them: two FAT-tables?) but then it just freezes, and CPU goes to 100 % and I let it be like that for 4 minutes, before aborting. Scandisk in windows is rubbish (fails to start), and running "chkdsk /f F:", in windows, results in nothing, the shell crashes immediately. Is it normal for fsck to get stuck and just chew up CPU? It does not seem to be reading from the drive, according to conky. Also, is it possible to run fsck as normal user, (at my work)?

Ubuntu Installation :: Bad Superblock - Wrong FS Type

I cannot for the life of me get my HD working again. I tried following all the various remedies I could find but to no avail.

e2fsck 1.41.4 (27-Jan-2009)
e2fsck: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda1
Could this be a zero-length partition?

ubuntu@ubuntu:~$ sudo dumpe2fs -f /dev/sda1 | grep -i superblock
dumpe2fs 1.41.4 (27-Jan-2009)
dumpe2fs: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda1
Couldn't find valid filesystem superblock.

It goes on and one like this. I'm stuck using the LiveCD for now (Jaunty) so I have some limitations.

Ubuntu :: Cannot Mount, Bad Fs, Option Or Superblock FSCK?

Aug 23, 2011

The HDD is a 500GB internal SATA, The smart claims that the "file system is not clean" but is still green.FSCK ran a few errors and using fsck i copied a new superblock from a backup location, It still won't let me mount and FSCK is still trying to fix a TON of errors. I'm sorry I don't know any of this yet, but I'm concerned that FSCK could be destroying the data on the drive, for example photos and other important things. FSCK is coming with a lot of things to fix, It's gone from trying to fix errors in free blocks of group #1 to over #3000.. Is this safe? Will this work? Can I get rid of whatever caused this problem in the first place?

I've searched a bit and have gotten *mount -o sb=n /dev/hda8 /home* as a potential solution but I'm confused about the value 'n' suggested. When run as I wrote it, it fails with a 'no such partition' error. Can anyone point me to a solution for re-creating the superblock to get this partition mountable again?
