How do I go about fixing files in ubuntu 8.04?

[cousinlucky]

I recently enlarged my ubuntu 8.04 partition and was notified to fix the filing system. I did a search here and nothing came up. Is there a way to locate filing errors and fix them because my computer has been acting odd lately? Thanks!!

Hi, Lucky!

This page should help:
Repairing Linux ext2 or ext3 file system

Also, from the same site:
Boot Ubuntu Linux into Rescue mode to fix system

Either one of those should help get you sorted.
If possible, you might want to get your hands on a LiveCD to do it, though.
That way, even the / partition will be checked.

That's scary stuff JD!!

[jayd512]

Not at all!
Use something like a Ubuntu LiveCD.
Open up a web browser to go to the links I gave you.
Open up a terminal and simply copy & paste the commands. I've used those steps on my own machine with no problems.
And it is also a Ubuntu install.

So JD I am supposed to run fsck on my ubuntu partition through the terminal of a disk boot-up - is that correct??

[jayd512]

Correct.
If you would like, post your output of sudo fdisk -l.
We can take a look at it, and make sure that this goes smoothly for you.

JD here is what appeared. Again, Thanks!!

I am assuming that your Ubuntu install is on /dev/sda1.
And Ubuntu 8.04 defaulted to an ext3 filesystem, so we're in good shape here.

From your LiveCD, open up a terminal, and paste this in:

fsck.ext3 /dev/sda1

That will run fsck on your drive, and use the correct filesystem check to do so.

As it runs, if it finds any problems, it will ask you if you want them corrected.

I'm pretty sure JD that my suse 10 os is on sda 1 and that my ubuntu 8.04 is sda 3 the large partition.

So edit the command to point at the correct partition.

fsck.ext3 /dev/sda3

You may need to use sudo for that command to work also.
