Ubuntu :: Error - Filesystem Is Not Clean
Nov 28, 2010
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.

I upgraded from 9.10 to 10.04 and during the upgrade it asked to install a new version of grub or keep the current one. Thinking that I should just upgrade the grub just to make sure that I had the latest version I decided to do it. So I told it the partitions to use the ubuntu, ubuntu swap, vista, and vista recovery.Finished the upgrade and restarted.I tried to boot into both the vista, and vista recovery but I noticed something weird. Grub switched the names, the actual vista install is called recovery, and when you tried to load it, a blinking cursor would appear for a split second and then loop back to grub. If you tried to select the vista recovery now called vista it would just sit at the blinking cursor for infinity. But booting into ubuntu worked.
So I decided to wipe ubuntu and do a fresh install of 10.04. Went through and set up the swap and ext4 partitions at the end of the hard drive(because I would like to expand the windows directory should I ever be able to boot into it). Now when I start up and select vista recovery now called vista it sits at the blinking cursor just as before.

I run Linux Slackware 13.1. I have a hard drive with a ext2 filesystem, and I would like to mark the filesystem as Clean without running FSCK on it. I think I can do that with the debugfs command, but in the help there seem to be only a command to mark the filesystem as Dirty?? Is there a way to manually mark a ext2/ext3/ext4 filesystem as Clean?

i've got an HP printer, a new one, and it's got an error code jamming it up. I tried to play musical printers between a windows 7 computer and my own ubuntu computer. this apparently generated the error, and now the printer is no longer working. anyone got a hack or program that can scrub the memory of an hp disk-jet F2480? or should i just throw the thing away and buy a new one?

I reformatted my root partition and boot partitions and installed ,averick but zhen I boot I get a grub 15 error. I might have made a mistake on the partitioning screen zhen I selected /dev/dsa6 for the GRUB bootloader - this is my dedicated /boot partition - and don't know how to fix it now
my current fstab is code...
By mounting all partitions one by one I can see now that everything has moved around so that
sda is the bigbastard drive - 500GB - that was sdb previously
sdb is supersize/basckup and was sdc before
the paritions on sda have moved to sdc
I have no idea hot to put everything back

Made a mistake while installing btusp for macbook. I know now that I shouldn't have deleted the installed files, I should have run "apt-get remove", but it's too late. Now whenever I install software or updates I get an annoying message about the btusb packages:Error! Cannot locate /usr/src/btusb-0.0.1.dkms.tar.gz.

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?

Is there any difference between apt-get clean and aptitude clean? Do they both remove the same caches? Should I know any other commands for cleaning up wasted space on my ubuntu laptop?

Ok so I just installed Ubuntu 10.10 Server Edition. On the very first boot, everything seems to run perfectly. I can SSH into it from any remote computer with no problems. However, the installation of certain things calls for a system reboot, which 2 days ago never would have been a problem. But now for some reason, the SSH server only wants to work on the very first boot of a clean install. After I reboot it, I get the ssh: connect to host 192.168.0.180 port 22: No route to host error. The absurd part is sshd is running! I've even tried restarting sshd, restarting the server, and using both 64 and 32 bit installs. The only way I can get anything to connect to it is by using ssh localhost. It won't even let me connect using the IP on the local machine!

I 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.
Code:

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 was running CentOs 5.3 and did a "yum upgrade" and got the following problem: Transaction Check Error: file /usr/share/man/man1/xdelta.1.gz from install of xdelta-1.1.4-1.el5.rf.x86_64 conflicts with file from package xdelta-1.1.3-20.i386

It seems that somehow multiple entries were made for the xdelta package - how do I clean this up?

I 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 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"):

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.

I had dual boot with windows 7 and ubuntu 10.04 running, and working. In my grub menu on startup I could choose (among things) something called Vista loader. Dont know why, since I installed windows 7 and not vista. Could also choose windows7 and ubuntu, both worked.
Today I accidentally pressed the vista loader, and now I get the following error upon boot: Error unknown filesystem grub rescue
So the next thing I did was download the latest ubuntu and boot from live cd. I followed instructions [url] on how to purge grub2 and reinstall it, and did so with out any problems. However the same error remains when I boot.

I just recently decided to install Ubuntu alongside windows 7 64bit. I was working fine until I decided to increase the partition size of the unused space to take up some space of an unused partition I had made earlier. When I tried to reboot windows I got the error -
