Ubuntu :: File System Damage Repair Or Reinstall?
Dec 11, 2010
I booted up Ubuntu after a couple weeks of downtime. I think it had just installed updates before I shut it down. It seemed fine. I started updating it, then it started giving me a bunch of errors about the root file system being mounted read only, so I had to reboot. I've heard that it does that if the file system is corrupted or there is a hard disk failure. When I rebooted, it kernel panicked on all but the oldest kernel which did a fsck and rebooted. Then I was able to get back in, but most of my panel applets are gone and cannot be restored, it fails to start x at boot with no errors and I have to start it myself from the command line, it is unable to do updates, samba is gone, whenever I update-grub to add Gentoo to the list, it doesn't stay there and the computer is really slow. I have backed up my home folder to another partition. Do you think I will be able to repair it at all or should I just reinstall?

My computer started acting flaky this afternoon and by the end of the day, became completely inoperable. When I reboot and login, I'm given only a Terminal window. I'm running Ubuntu 10.04 LTS, although the Lynx is not very Lucid at the moment!
1). First sign of trouble was yesterday when I was running Win XP as the guest on Virtualbox. XP became unresponsive - at least the mouse could not push any buttons. I had to do a cold shutdown by right-clicking the "close" button at the tab on the bottom Gnome panel. This problem repeated itself today.
2). I attempted (and I thought, succeeded) in upgrading OpenOffice.org to version 3.3. OO seemed to work fine, but after this install I started seeing problems.
3). I attempted to remove Pulse Audio via Synaptic, but instead of removing only Pulse, pieces of software started flying out of the machine (so to speak) at an alarming rate. It happened too fast to count them all. I think the entire desktop is gone along with many individual programs (such as Kaffeine, being one that I noticed).
Currently, I'm running a backup copy of Ubuntu that I keep on a separate hard drive on the same machine. I can access my files from here, and yes, I've backed up my home folder from the other disk!
When I reboot to the damaged system and I get the terminal window, how should I repair the damage? How do I find out if the damage resulted from broken or missing software, or both? Should I try to load Synaptic from the terminal, and if so, how is that done?

I fouled up the file system when removing a drive. How do I fix it, or do I need to re-install?
The system boots to the point in the GUI where it checks the file system. It then suggests that I run fsck without the - a and -p options, and the drops to a sheel.
I enter the root pwd and then it says: "(Repair fileystem ) 1#" What do I do from there?

I'm using Ubuntu Lucid and any sudden power loss will usually cause problems with the file system. When I bring the computer back up, Ubuntu will then scan for errors at boot-time and if any errors are found it prompts me to select whether to repair or ignore them. I would much rather have it select the repair option automatically so that I don't have to be physically present.The reason for this is that i have a web server that should come back online automatically after a power loss.

I had previously installed windows xp. Then I installed ubuntu and dual booting was fine. Now my windows is corrupted. I need to either repair or reinstall it, and I think my mbr will be affected. I will test all this on vmware first.

16GB RAI've been running the Debian-based Proxmox VE on it for six months or so with no problems.Today I loaded Centos 5.5 x64. During a reboot, the file system crashed and fsck couldn't repair.I loaded it again, did all the updates, and loaded my applications. On about the third reboot, it crashed again and fsck couldn't fix it.I don't really know where to begin. I doubt seriously that any hardware has went bad since yesterday.

I have a new lenovo thinkserver hardware. I was configuring my newly installed kernel (slackware 13.1 - kernel 2.6.33.4) maybe to weeks now. I was testing the configuration of the kernel parameters.Suddenly out of the blue my BIOS started to report memory error. I have 6 Fully buffered memories in pairs. Four has no advanced ECC and two supports ECC.It is possible to damage the memory by some wrong kernel configuration???I cannot believe that this is possible but I cannot see any other explanation how can a two weeks old hardware get wrong.

On startup I heard a 'click' around the time "loading hardware modules" and "loading kernel drivers" was showing on the monitor. Then all the system sounds became fuzzy (corrupted?). Other sounds, such as VLC playing a music station, are fine.

I get this message when I boot
init: udevtrigger main process (440) terminated with status 1
init: udevtrigger post-stop process (449) terminated with status 1
init: udevtrigger main process (447) killed by TERM signal
I'm now on the live cd, is there anyway to either fix that, or just repair the system? I tried booting in safe mode too, none of those started up either.

OK, so about a week ago or so my Ubuntu 10.04 install no longer recognizes my iPod Touch or Iphone. I have had no luck getting them to work. i REALLY do not want to fresh install Ubuntu. Is there a way I can like repair or restore (a la "Window$") that will fix the OS itself without removing any programs or settings?

My system got stuffed after a trivial online update, it downloaded a new kernel update, I rebooted and now it won't boot at all saying "FATAL: Could not load /lib/modules/2.6.31.8-0.1-desktop/modules.dep: No such file or directory", then some stuff, then "mount: unknown filesystem type 'ext4'", "could not mount root filesystem"... It's on my laptop without a DVD drive and I've only got a LiveCD USB stick which doesn't have a YAST system repair tool. Is there any way to repair a system without a DVD drive?

I have a laptop with 250 GB SATA HD that has the following:
Win7 Pro installed first with sda1=system reserved partition, sda2=C: drive, sda5=separate software application programs to differentiate from Windows' Program Files. Ubuntu 9.10 was installed next (sda6=common swap partition for all Linux distros, sda7=Ubuntu root, sda8=Ubuntu home). Then Opensuse 11.2 was installed with sda12=root and sda13=home. Finally FedoraCore11 was installed with sda9=boot, sda10=root and sda11=home. Ubuntu and Suse have grub loader in their own root partitions.
Suse's grub menu controls all OS's. From this grub menu I can select Windows or any other Linuxes. Suse uses legacy grub because it was installed right after Ubuntu 9.10 which uses (legacy) grub.
Here is opensuse's grub menu:
# Modified by YaST2. Last modification on Wed Mar 31 11:49:28 EST 2010
# THIS FILE WILL BE PARTIALLY OVERWRITTEN by perl-Bootloader
# Configure custom boot parameters for updated kernels in /etc/sysconfig/bootloader
default 1
[Code]....
Somehow I also messed up Windows' boot file and boot partition table. Now I am still trying to use Windows installation CD to repair Windows but it has taken several hours and am still waiting for screen response. I cannot boot into any Linux distro either.

I want to use the live cd (Linux mint 9) to do a repair install on my system, but when I start, it says that it has detected another instance of linux and this must be removed before I can continue. I don't want to do this as I have a lot of data on this system and I don't want to lose it. The error occurred when I did a dist-upgrade and installed new kernels. Before I installed the kernels, a message came up saying the following packages are already installed but are no longer required. Use apt-get autoremove to remove them. I did this and now when I boot, I get as far as the five changing dots on the screen and it just stays there. I went into command line and ran apt-get mint-meta-main mint-meta-gnome, and at the end it came up with problem with /etc/utilities/desktop.

When I attempt to boot into Ubuntu 9.10, I get the error: "Error 15: File not found" I know the reason for this - I deleted it - Doh. A latest upgrade told me I didn't have enough room in the boot partition to install the latest files, so I thought it would be a marvellous idea to remove the old stuff, to give it some room. I obviously deleted something that I needed by mistake. I was using synaptic to do the remove & thought I would be safe. A good learning experience.
In grub menu I have options: Kernel: 2.6.31-15 - generic and also its recovery option, both of which get the same error. (It's a dual boot with XP as the original os). Ideally I'd just like to get the latest working kernel and put it somewhere appropriate, rather than do a full install. Is this possible and if so how? I have a separate boot partition (in dev/sda5), swap (sda7) and Linux (sda6).

I have installed windows 7 back to its former state in after foolishly messing around with some installation options in an Ubuntu install (this caused windows to disappear, and me to repair it). In *repairing* windows, I overwrote my grub file and the boot options for Ubuntu, so that it looks something like this:
Disk 1: Primary Partition - Windows 7
Disk 1: Secondary Partition - Windows 7
Disk 1: Secondary Partition - Free Space ( this is where I have Ubuntu installed)
How can I repair my grub file so that I can boot into my Ubuntu installation?

Im probally just being a noob here but for the projects sake I thought it would be good to identify this problem. I have an old advent laptop and I tried to install Opensuse from DVD on it. I followed the installation as normal but when I tried to boot it said some sort of check was forced and then I have to enter the admin/root password upon doing this I got the message system repair # in red. I have tried to repair the system through the installation DVD and tried re-installing it but I still get the same message.

It used to be that the dvd menu offered an option to "repair the installed system". THis was really very convenient. The openSUSE 11.3 dvd for x86 now only gives a "system rescue" option which leads to command line directl. Where have been "the repair the installed system" tools? How can we access them now? What is a reasonable set of tips that's supposed to be used after logging into "system rescue"?

The new GRUB2 was supposed to configure itself from the old grub, but got the kernel image partition wrong.I have booted from Knoppix live cd, but need to write to system files. I have searched, and found several suggestions that apparently work on Win machines, but RO permission for root on Linux is a harder nut to crack.
