Ubuntu :: Any Way To Repair WXP Boot Using FSCK?

Feb 25, 2011

I need to boot in WXP just because the guys at the company don't want to update for Linux drivers in the TS so I can't connect from home unless I do it in Windows XP. But today WXP refuses to boot, when the progress bar appears, the system boots automatically. The WXP CD doesn't help, the repair console doesn't let me run chkdsk or anything (dir C: gives an error about listing addresses or something like that). Is there any way to use fsck or anything in Linux to repair the WXP NTFS partition?

Ubuntu :: Fsck Usr Fails And Unable To Repair?

Dec 2, 2010

I am travelling so would really appreciate a few tips that should hopefully get my pc running again. (I have internet access via a kiosk, and can burn a disk if necessary, but the smaller the download the better)I have a few ideas that with some help I should be able to fix the partition.1. Is there a simple way to use use grub, to mount all partitions read only and not to fsck them so I can logon in normal user and sudo and hopefully fix the parition?or 2. Download a small version of ubuntu or something that I can burn to CD (my machine cannot boot from usb) so that I can repair the machine.3. Download the ubuntu installer (alternative) and try and reinstall the necesary usr partition?

Hardware :: Corrupted Drive- Mechanical Or Logical - Fsck Repair?

Sep 7, 2010

I was working on my RHEL 5.2 workstation yesterday when the OS became flakey. first I noticed that some software that I had running was outputting and error that it was unable to write to log file because permission was denied - I've never seen this output before- it would have been writing to my home dir running under my user name. From an open terminal, i did "ls -al" and saw that many of the permissions the files in my home dir were listed as "????????" some were still "rwxrwxrwx", as well, many files were highlighted in the colors set for links and root privileges.

I tried to start a new terminal, and it failed. then Gnome crashed. When I reset the Machine, I got through grub, and into the startup, and after finding the Volumes, the startup failed with a Kernel panic:

giving several errors- like:

I dont have much experiencie with this stuff, but it looks obvious that somethig like the MBR or wherever the partion information is stored might have been corrupted.

What I dont understand is why I can get into GRUB (its a dual boot Windows Vista, RHEL machine). I'm guessing that this means its not a mechanical problem, because I can get RHEL to begin to boot which i think is failing somewhere around the /etc/rc.d/re.sysinit script, and also can get Vista to bring up the inital windows screen and a mouse pointer on spanning both of my screens which i think means that it must have at least loaded my ati drivers for my dual head radeon 4850. windows hangs there however.

I've tried the RHEL 5.2 rescue disc, and it doesn't recognize any Linux partitions.

I ran the system diagnostics out of the dell bios and it came back with a failed HDD : Error code 0142, but from digging around a bit I've found that this is a very broad diagnosis.

My concern over it being a mechanical problem is that I'm not sure that I want to try to run any further diagnostics, or any of the disk utility programs that i've seen listed here on linuxquestions, as it might damage it further, and there is some data that i would really like to get off this disk.

Installation :: During A Reboot File System Crashed And Fsck Couldn't Repair

Nov 12, 2010

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.

Ubuntu Security :: Main Encrypted LVM Not Accessible After Deleting A Different Encrypted LVM On USB HD

Mar 7, 2011

I installed Ubuntu 10.10 64 on my laptop with the entire 500gb setup as encrypted LVM. This has worked well for several months with no problems. During this time i have been backing up the data to an external usb drive (1tb) on a regular basis. The usb drive was not encrypted. So, I thought it would be a good idea to encrypt the backup drive too. I wiped out the backup drive and set it up as one large encrypted lvm and mbr. This seemed to work fine but immediately afterwards I decided to erase that and set it up as encrypted lvm guid instead of mbr. I couldn't delete it while logged into my desktop so i decided to do it from a bootable gparted usb stick. In gparted i erased the 1TB backup drive once again and planned on setting it up the way I wanted once I was logged back into my ubuntu desktop. Now I cant boot into my desktop with the following errors:

cryptsetup: evms_activate is not available b0d) does not begin with /dev/mapper/

Then after waiting for a few minutes I get an error followed by (initramfs)

When booting from a live version of ubuntu the 250MB boot patition is recognized and 500 partion is there but it is labeled as empty/unused.

Also, I did choose to use the exact same passphrase as what is used on the main bootable drive when I set up the encrypted partition on the external 1TB drive.

Ubuntu :: Where Are Fsck Results?

I forced a fsck on the next boot by.Code: sudo touch /forcefsck.Where did the results go?/var/log/fsck/checkfs and /var/log/fsck/checkroot both read "(Nothing has been logged yet.)" Am I to assume that if there are no errors nothing is written to the log files?

Ubuntu :: Fsck Terminated With Status 8?

Aug 24, 2010

I booted up my laptop and the boot sequence got stuck at the boot splash screen (plymouth). I did an esc and I saw a failure message, the error I remember in my panic mode is: fsck terminated with status 8

I rebooted, got the same message. Rebooted again and this time, to my relief, it worked.

1) What happened, should I be concerned? Not sure why it worked after 2 reboots.

2) Is there a possibility this could happen again?

3) Are there any boot log files I could look at?

4) Is there anything I can do to fix this? Or a check of some sort?

I'm using Ubuntu 10.04 on a Dell Studio 1535 laptop. No dual boot. The disk is partitioned and I've got my /home folder on the other partition for situations like this.

Ubuntu :: Force A Fsck Run At Next Reboot?

Nov 28, 2010

I know I can force a fsck run at next reboot using

Code:
shutdown -rF now

or

Code:
touch /forcefsck

can I force the fsck to more indepth checks such as doing directory optimisations, bad blocks checks, etc. maybe by passing parameters to the fsck call during startup?

Ubuntu :: Run Fsck On Keypress During Boot?

Jan 4, 2011

I am wondering if there is a way to manually trigger a file system check during boot by pressing/holding a key. Maybe there is already a keyboard shortcut built in to do this?I know that using tune2fs you can modify the number of boots (mounts) between file system checks, or even use "shutdown -rF" to reboot the system and force a file system checkAlso, I do not want to force the user to choose to run/skip the file system check during boot. For example, prompting the user with, "Do you want to run a file system check [y/n]?" each boot (or even each time the system thinks it should run a file system check),s not desirable

Ubuntu :: Unable To Fsck Ext4?

Jan 24, 2011

Seems like I misplaced this topic. Should have been in general help. Sorry! Any moderator feel free to move this topic. As I was creating a swap partition, something went wrong and I ended creating a much bigger file which consumed all my empty space. Ubuntu stopped working and now I can't seem to fsck / mount my disk. Currently I'm on a live cd. fsck will give:

Code:
e2fsck 1.41.12 (17-May-2010)
fsck.ext4: Device or resource busy while trying to open /dev/sda2
Filesystem mounted or opened exclusively by another program?
However, the file system is not mounted.

Ubuntu :: No Init Found, Cannot Fsck?

I've been through [URL].. which is VERY close to my problem but I cannot get Disk Utility to work when running off my Live USB. Asking it to check the hard drive results in it telling me the filesystem is 'not clean'.

Ubuntu :: Automatically Run Fsck Every Few Months?

Ubuntu :: Using Fsck To Check Windows Partition?

Mar 21, 2010

My windows partition isn't starting up, gives an error and suggests using chkdsk. However, I cant even reach safe mode or command prompt. I can still access my Windows hard drive through Ubuntu.I am wondering I can use a Linux tool to perform a check on this Windows partition? I found the fsck command, but I am confused about the warning about running it on a mounted system and about what exactly is a mounted system.

Can someone please tell me how exactly I wod go about doing a check on this partition? Its currently located in /media/disk.I can right click on the partition and unmount it. But if I do this, will Ubuntu still be able to see this partition?What command do I use to do fsck only on this Windows partition (and not the whole system and other mounted places)? How do I remount the Windows partition so that I can atleast salvage my data easily in case doing a disk check does not help?

Ubuntu Servers :: How To Cancel Fsck At Boot

Mar 22, 2010

Right now I am trying to fix the problems on my server with daemons not starting.

So I have to try different solutions and reboot.

The problem is that after 28 reboots, fsck kicks in and decides to check 2 TB of data.

Is there a way to cancel this???

It takes forever, and by the time it will be done, I will have forgotten what I was testing.

The issue of daemons not starting becomes even more frustrating when fsck decides that I must take a half an hour break.

So again, how do I cancel the fsck on Ubuntu Server?

Ubuntu :: Fsck On Busy Device Or Resource

Apr 4, 2011

I am dual-booting my Gateway laptop with Windows XP Media center Ed. and Ubuntu Notebook 10.10. Several weeks ago I was in the midst of downloading a program from the software center and my system starts running slow (this is in the Ubuntu kernel, not the Windows OS). So I decided to cold-boot the laptop in mid-download. When it boots back up, I get dropped to a grub-rescue menu that states the following:

Code:

Now, the only way I can even remotely use my laptop at the moment is to use my Live USB with the corresponding version of Ubuntu Netbook 10.10 or the Live CD I made with Ubuntu 10.04 on it (I'll explain why I made this below).

I read somewhere that I need to run fsck on my device to try to fix the partition, which btw my Ubuntu partition on my device is /dev/sda5, and before someone suggests it, I even tried using GParted and it doesn't work.

The reason I made a 10.04 CD is because I read somewhere that using the fsck from 10.04 might be more effective (for whatever reason) than the 10.10 fsck version.

I'd also like to add that I'm incapable of booting onto my Windows OS at all, yet I can access the partition from my Live CD/USB. the Ubuntu partition however, I can neither access or mount.

I tried running fsck on the entire device partition table, and I get the following:

Code:

This is me running fsck from the 10.04 version, I get a similar msg from the 10.10 Live USB but replace fsck.ext2 with fsck.ext4 in the message.
