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.

I'm trying to format a 32GB USB flash drive to ext3 for Linux.
Code:
sudo tail -f /var/log/messages
shows me:

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?

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?

I had left a small windows partition for some programs like MS Office, (I'd failed to install it with wine :-( ) so I was dual booting OpenSUSE 11.3 & Vista. When I decided to replace Vista with Win 7, the grub was missing, I formated the Vista partition, then tried to boot into SUSE before installing win 7. there was some command line, that i tried the instructions I had found on the forums so I typed
grub
find /boot/grub/menu.lst
and I got (hd0,1) so I
root (hd0,1)
[code]....
I got an error about missing (hd0,1), when I pressed enter I got a menu not the one I was used to. When I chose to boot OpenSUSE 11.2 or the failsafe I got error 17 "cannot mount partition" so found a bit of assistance from the following page: How to fix GRUB after Windows breaks it, and how to edit the GRUB menu - Super User when I press "e" and change root (hd0,1) to (hd0,2) then boot by pressing b, I get the usual SUSE boot screen, then the bootup process stops with some text displayed on the screen. there was a lot of text but the following is what I jotted down: the superblock could not be read or does not describe a correct ext2.
superblock corrupt e2fsck with an alternative superblock
e2fsck -b 8193
fsck failed. Mounting root device read-only

Gparted won't let me install Ubuntu 9.10 64 bit. Every time it hangs at 47% and throws a sector size error, something like: doesn't support sector size 2048 and the code is HIGHLY EXPERIMENTAL. My 1TB hard drive exists out of the following partitions:
100MB Windows 7 Reserved
900GB+ Windows 7
30GB EXT4
1MB unallocated space
Is there a workaround for this? I've tried installing Linux Mint and Ubuntu but both gave me the same error.

I have a netbook that has a dead windows partition. I've installed ubuntu and have never tried to recover the dead windows installation. However, I now need that space in the main partition. I ran the liveUSB of ubuntu and ran gparted. I have an error on that partition.
Accounting clusters...
cluster accounting failed at 66892 (0x1054c): Missing cluster in $bitmap
Cluster accounting failed at 489569 (0x77861): extra cluster in...
I think I may have attempted to resize this and I got this error. I cannot get into windows to fix anything, so I can't run scan disk or fix disk etc. I'm not sure if I can get a command prompt. I don't have a CD drive. Can I reinstall linux and use the entire hard drive? Will it do this, or will the cluster errors prevent this? Can I fix this so to resize the windows partition?

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?

During the file system check of an ext3 partition at boot I get the following output:
The super-block could not be read or does not describe a correct ext2 filesystem. If the device is still 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 super-block:
I'm then forced to login in as root and given the following prompt:
I'm reluctant to do as advised by the output and run e2fsck -b because it is not an ext2 filesystem.
Although I can still enter runlevel 5, it doesn't seem to recognise mouse and keyboard input in KDE so my system is effectively redundant at the mo. For this reason any short term workarounds are welcome, but a fix is needed. This problem is part of a longer saga to do with recovering a Windows Vista installation which started failing to boot. I have used both Vista and SUSE tools to try and recover my bootloader to no avail, and this has been the result. If more detail about this is needed please ask and I can explain what I have done.

I was trying to move my home partition on Ubuntu, and the computer hibernated on me. I restarted it up on the live disk to survey the damage, to find that the home partition, according to fsck, "Superblock has an invalid journal (inode Clear? <y>"
It cannot be mounted, either.

i used to have ubuntu 9.i decided to move to sabayon so i used the live cd to install it ,resize the ubuntu partition and use the remaining space for sabayon.while the resizing procedure i got an error(i dont have a copy of the error log file but i know it has something to do with an anaconda process).i aborted the installation and the result was an filesystem that couldnt be mounted.when i try to mount the hdd i get this:
Code: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try

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.
Code:
ubuntu@ubuntu:~$ sudo e2fsck -f /dev/sda1
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?
Code:
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.

I downloaded the new gparted (6.4.1 I think) and when I try to run it from a live cd in the default settings it keeps telling me that it can't find my screens. I have an intel video card. I haven't had this problem with older versions of gparted. I suppose I could use an older version, but I'd like to know what the problem is.

think my partition table is messed up but i am not really able to fix it with my little knowledge about testdisk and fdisk. This is what the command fdisk -l -u reports:

I was upgrading Ubuntu to Natty last night, but it crashed just before completion. Then, I couldn't mount the drive so I'm now booting it from the live disc. I go into gparted, but it gives me an error saying:
Can't have a partition outside the disk!
I have /root and /home in separate partitions, so I must find a way so that /home can survive. I've run testdisk and this is what I get:
Code:
Disk /dev/sda - 160 GB / 149 GiB - CHS 19458 255 63
Partition Start End Size in sectors
>* FAT16 >32M 0 1 1 14 254 63 240912 [DellUtility]
P FAT32 LBA 15 0 1 4192 254 63 67119570 [NO NAME]
[Code].....
There are only 2 Linux partitions, Linux and Swap, so it seems that my /home has disappeared! Is there a way to recover it? Also, how do I fix Gparted's complaint?

I have 3 Ubuntu installations & a PCLINUXOS, plus Windows XP installed on one hard disk. I still can boot to each one of them and can mount each one using Ubuntu.
The problem "may" have occurred when I reduced the size of some linux partitions using gparted. I still have plenty of space in each of those partitions.
When I started gparted all of the HD was unallocated. I did that from each ubuntu installation and the PCLINUX installation, plus LIVECDs. All indicated the space was unallocated.
When I did an fdisk -l from a Puppy Linux LiveCD I got a normal start and ends of each partition.
When I tried it from Ubuntu installation or live cd, I received the following types of responses:
Code:
ubuntu@ubuntu:~$ sudo fdisk -l /dev/sda5
Disk /dev/sda5: 28.5 GB, 28566397440 bytes
255 heads, 63 sectors/track, 3473 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
ubuntu@ubuntu:~$ sudo fdisk -u /dev/sda5
The number of cylinders for this disk is set to 3473.There is nothing wrong with that, but this is larger than 1024,and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Plus the Windows partition seems to go over its limits.
Since all of my OS installations are still working, I don't know how critical this is. From reading another post, I understand this might be able to be fixed by making some changes in fstab.

I just got a new hard disk so that my "/" and "/home" partitions would be located at their own separate drives. All was well until i tried to expand my "/home" partition to fill up the entire drive that used to also have the "/" and swap partitions on there. Let me sketch the before-and-after scenario in GParted,
Before:
What actually happened after:
Gparted gave an error prompt after which i found out that the entire ext3 partition (/home) had been moved to the left but not yet expanded to the right, which is of course not a problem. However, for some reason it has labelled the entire ext3 partition as a swap partition!
I'm still running ubuntu from the usb flash drive, because i dont want to risk that the (120GB) swap area will actually be used and cause my data to be lost.
I guess my question is, can i relabel the swap partition as ext3 like it was before without formatting (ie without losing data)?
Here's the output of "fdisk -l", which doesn't show the swap area (the drive in question is "/dev/sdb"):
Code:

I have a problem in my ubuntu 10.01 that it can't load a drive/volume in ubuntu. When I tried, it said: "Unable to mount location Error mounting: mount: /dev/sda1: can't read superblock". And when I boot my pc with 'Windows', it said : "UNMOUNTABLE_BOOT_VOLUME" under a blue screen. What can I do to solve this problem?

I have a new 1.5tb internal drive I want to partition as NTFS (because Windoze machines need to see/use it) and in gparted, when I go to partition -> new, it says it could not add this operation to the list a partition cannot have a length of -1 sectors. I recall having this issue on my 2tb external drive and I ended up creating the NTFS parition on a Windoze machine and then bringing it to the Linux box but since this is an internal drive, that's not an option. I took all the defaults in the "Create new partition" screen.

I have always been amazed that despite the fact that the liveCD obviously has gparted on it, that it is doesn't install it. Why not?I understand it is a tool with which you can easily damage your system, but that's no reason not to give it to users, once its aready taking up space on the liveCD.

I have been trying to resolve this issue and it's bewildering me... I have been trying to do the install on Ubuntu Netbook Remix (UNR) and after setting up the keyboard language the installer locks up. The error message mentions it was unable to launch Gparted as it crashed.
I have also tried to launch Gparted from the system admin apps and Gparted will show it is trying to read the hard drives and then crashes. I have tried updating Gparted from the repo's and on launching it also crashes too.

I have some problem, the gparted 'searches' for ever on one disk only, even after 20-30 mins it is not finished and it has to be stopped manually.
Tried the same with debian, which has gparted 0.38, and the all works fine.
