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?
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?

This problem has arrived again.......I tried the same solution but didn't work out...the problem is described below.
I use Ubuntu 9.10 .
I did this in Ubuntu 9.10 live CD.
quote from terminal :-
ubuntu@ubuntu:~$ sudo mkdir /win
ubuntu@ubuntu:~$ sudo mount /dev/sda5 /win
ubuntu@ubuntu:~$ sudo mkdir /vdisk
ubuntu@ubuntu:~$ sudo mount -o loop /win/ubuntu/disks/root.disk /vdisk
[Code]....
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 <device>
ubuntu@ubuntu:~$ "
> ^C
ubuntu@ubuntu:~$
^^ quote ends.
I'm logged into a server through the CLI and did a df -T and confirmed all my volumes are ext3. but when I do a tune2fs -l /dev/sde it tells me
tune2fs 1.39 (29-May-2006)
tune2fs: Permission denied while trying to open /dev/sde
Couldn't find valid filesystem superblock.
I don't have root access on the server, but is that why it's complaining, or is my syntax incorrect?
I added an ext4dev filesystem to my hard drive as /dev/sda3 and mounted at /share with the goal of putting all of my multimedia files on it and sharing it through NFS. I followed this guide: [url]
Of course, this was from lenny (hence the -dev). The partition was fine, and I mounted it numerous times. I also performed a dist-upgrade to squeeze. I shutdown that computer with the usual 'shutdown -h now' and disconnected the AC power cord from it, because I wasn't planning on using that machine for awhile. As far as I could determine, everything was fine before I unplugged it.
Every time that computer is powered off, the clock resets to 1999 because the battery is bad. So I am used to getting the "last mount time is in the future" error.
Three weeks after halting, I powered the computer back on. It was unplugged until this point. I got an error message when it attempted to mount /dev/sda3
I then removed its line from /etc/fstab, rebooted. and tried to check it, but I just keep getting the same error-- even with the '-b 8193' option.
The machine is still using the 2.6.26 kernel from lenny. I am building a new one right now (2.6.30), hoping that the problem is caused by the ext4dev/ext4 module. Otherwise I don't know what to do.
Today for strange reason, one of my Ubuntu 64 bit server Linux VM failed to start ? it stopped in the FSCK scan status with the error as attached. few days back I've added new hard disk successfully and format it as sdb5 without problem.
View 3 Replies View RelatedI 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 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.
what does this error message mean? im trying to mount an ipod in disc mode. let me know if there is a way to manually mount it to get around this. but not too technical, the simpler the language, the easier i will understand it.

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,

I am very new to linux, and I have a question regarding the filesystem check (fsck). The power recently went out and when I tried to restart linux the following error appears:
*/dev/sda1 contains file system w/errors, check forced it then goes on to say..
*An error occured during the file system check. Dropping you to a shell; the system will reboot when you leave the shell. Give root password for maintenance (or type Control-D to continue) I wasn't sure what to do, but checked some other online forums and they suggested running fsck manually - so I typed in the root password - and used the command, "fsck -A -V ; echo == $? ==" it then gave the following message
*WARNING!!! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage
*Would you like to continue (y/n)
Again, I wasn't sure what to do so i just checked no. I then manually turned off the computer and was prompted at the beginning to press Alt-3. I was brought to another screen and it informed me one of the drives was degraded and suggested rebuilding the array. I tried doing this, but it still brings me back to the original error of, "/dev/sda1 contains file system w/errors, check forced," and the process continues.
Also, when I tried to rebuild the array, I didn't backup any of the data on our home directory before doing this (which was probably a big mistake). After being prompted to type the root password, I was able to give the ls command and look at all the directories...the home directory where our data was stored was empty and I am afraid I may have lost some information. Is there a possibility that data was lost when I was trying to rebuild using the old drives?
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?

View 9 Replies View RelatedI have a dual boot system with ubuntu 9.10 x64 and Windows 7. Everything has been working fine for a a long time but yesterday I tried to delete an unused partition through the Disk Utility in ubuntu (System->Adminstration->Disk Utility) and everything was messed up. I used to get the "Grub error: Unknown filesystem". I managed to create an ubuntu bootable usb and followed some tutorials for fixing grub but all i managed to do is to get another error: "Grub error: No such disc". After some experimentation i got
"Grub stage 1.5" which gave me a grub> command prompt./dev/sda is the drive containing Windows and Ubuntu.

I went away for a few days but left my computer on to seed torrents. I come back today to find that my flatmate decided to have a tidy up, unplugging my computer and external HDD in the process...I set my computer back up but now my external drive is refusing to mount. This drive has EVERYTHING on it - about 5 years worth of music & video d/ls plus a lot of important documents so I'm praying that it isn't wrecked.That I know of, the drive was mounted but not in use when the power was pulled. The disk utility recognises its there and SMART-healthy, but claims "Filesystem is NOT clean" and won't mount it.

View 3 Replies View RelatedI have a laptop with windows7 and ubuntu installed. When I installed Ubuntu it created 4 partitions (2 for swap and 2 for ubuntu). Yesterday, a friend of mine deleted one of the partitions (swap+linux) because they weren't being used (weren't even mounted) and he thought I could use the free space. I kept on using the laptop but today I had to reboot it. Instead of getting the usual grub menu I got this:
Code:
error: unknown filesystem.
grub rescue>
I tried using the solutions I found in lots of posts related with this matter but I couldn't fix it. What I tried was this:
Code:
#show you the available partitions
ls
#look for boot files on the partitions
ls (hd0,1)/boot
[code]....
The problem is that it doesn't recognise the commands 'linux', 'boot' or 'initrd'...
The other they my laptop totally halted in the middle of a luks-encrypted external-hd copy operation or such.After a hard poweroff and reboot, the linux procedure would halt at the
Code:(initramfs) line and couldn't be pushed further. I booted with a LiveCD, ran sudo fsck /dev/sda1 and answered yes to a bundh of filesystem-fixing prompts. Yesterday the it happened again: freeze then incomplete boot with same error message. Do you have an idea of what can be causing it? How can I diagnose this problem?
I just accidentally clicked on my ubuntu drive when I was in PCBSD Unix and I had somehow glanced at a few things. When I tried, it didn't really let me in as much, but it said something about an access error and denial when I looked with the KDE Dolphin file browser.All I did was leave the rest alone and reboot but then got this when attempting to access Ubuntu:----------init: hwclock main process (366) terminated with status 29564.General error mounting file systems.---------- also got back into BSD and formally unmounted and rebooted again, but to no avail.

I am not able to access the harddrive. I am very new to ubuntu.
I have been using ubuntu 9.10 for a month. i have it installed on a 5GB separate partition of a 80 GB hard disk with my XP installed on a C drive(a separate partition ofcourse) then i had to remove it from my PC so i boot my PC with a partition manager cd and directly formatted that partition of 5GB from that software now i am having this error on my boot of PC....
grub rescue> error:unknown filesystem
I have tried a lot of commands here on this screen and nothing happens...i want to go to my XP .... and can't loose my XP OS and other data as well on different partitions.....
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:
there was ubuntu on my pc operating system but it is strange for me so i wanted to instal windows 7 on my pc. I inserted Window 7 disk and started to install it and i formated Ubuntu but the disk what i was using was damaged and it could not complite the installation and now i dont have any programs in my pc. Problem is that i got another disk but i cant boot anymore my pc, i select drive and stuff and then comes error.
error: unknown filesystem grub rescue- i tryed different commands but those didnt worked.
I am using Ubuntu 10.04 and am having a major issue with it not booting. My PC worked fine yesterday but when I tried to boot this morning I get the error "error: unknown filesystem" and under that I get the "grub rescue>" prompt.
At first I thought this was just a problem with Grub that would be easy fixed so I put in my Ubuntu USB and loaded it up in live mode. But when I try to look at my file system from within the live environment I can't seem to see any of my files.
I have looked at the drive in GParted and my main file system (/dev/sda1) shows up as 'unknown', while the swap partition (/dev/sda5) shows up as it should. I have also looked at the drive with the Disk Utility and the SMART Status says the disk is healthy.
I am really concerned about this as currently the system is totally unable to load, not only that but I am also unable to recover my data from the drive which is my main concern as I havent done a backup for quite some time and I have a lot of python code that I have been working on that I really need to get back.
Has anyone got any idea of what to do and how I might be able to sort this out or at the very least recover all my data. I can't understand why this has happened I have not made any changes to the system recently other than installing the updates that came through yesterday. This is a really urgent issue for me and any help will be very appreciated.
