sda1 corrupted and unmountable

[fmigpaulo]

I got the same problem. What happen has that my Ubuntu 10.10 was updating and then the daemon died (maybe because i was running firefox at the same time and there was a firefox update??).

With the daemon killed there was nothing i could do: opening terminal just open a grey background window, could't mount devices saying that they were read-only files, and to shut-down i had to use the shortcut that shows when ctrl-alt-del is hit because the other shortcut only display an empty dialog box.

Exactly the same has just happened to me today. Windows portion still works absolutely fine so I don't think it's to do with the hard drive?

HELP!

Edit: the only difference is last time I shut down, I shut down with no problems. Don't think I installed any major updates

is there a way to see what process is keeping the fsck from running and then kill that process? I have sda1 which is windows, sda2 - ubuntu and sda 3 which is swap. Fsck runs on sda1 with no errors, just gives a message saying everything is fine. SDA2 no luck and cannot run on sda3 as a swap portion.

[fmigpaulo]

lsof | grep sda2

##SIGTERM
kill process_id_nr
## OR
##SIGKILL
kill -9 process_id_nr

Thanks, and that will just kill the process that's making it impossible to run fsck whilst booted from a livecd? Just want to know what I'm doing when I'm doing it!

Ok, I tried it anyway and got this output:

ubuntu@ubuntu:~$ sudo lsof | grep sda2
lsof: WARNING: can't stat() tmpfs file system /cow
Output information may be incomplete.
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/ubuntu/.gvfs

jbd2/sda2 504 root cwd DIR 0,17 280 2 /
jbd2/sda2 504 root rtd DIR 0,17 280 2 /
jbd2/sda2 504 root txt unknown /proc/504/exe

So would I now do a kill process_504?

edit:

So I killed it, and now when running lsof....sda2 i get:

ubuntu@ubuntu:~$ lsof | grep sda2
lsof: WARNING: can't stat() tmpfs file system /cow

After a restart yesterday, my computer doesn't boot correctly...
After GRUB, it prints

mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
Target Filesystem doesn't have /sbin/init.
No init found. Try passing init=bootarg.

BusyBox v1.10.2 (Ubuntu 1:1.10.2-2ubuntu7) built-in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs)_

and falls to the busybox prompt...

The problem is when i try

sudo e2fsck /dev/sda1

with any switch it prints:

ubuntu@ubuntu:~$ sudo e2fsck /dev/sda1
e2fsck 1.41.12 (17-May-2010)
e2fsck: Device or resource busy while trying to open /dev/sda1
Filesystem mounted or opened exclusively by another program?

When i try to mount the disk, the console just hangs.(it doesn't become unresponsive, the cursor just goes to the next line and doesn't do anything else) I tried leaving it for about 15 minutes in case it was checking the disk but nothing happened.

I don't care about restoring the system (i was gonna reformat anyway), all I want is access the data so i can backup (mainly my firefox profile).

Hi i had the same problem yesterday, the fsck command didnt worked too, in my case the problem was that ubuntu live cd was auto mounting the partinion, so it fsck didnt worked.

But it worked when i tryed fsck command in slax.

Thx to tensorpudding from #ubuntu channel for helping me out to solve the problem

That fixed it! Thanks so much, such a simple workaround when you know how!

Slax did the trick. You guys rock!!
