Thanks

You have something wrong in your /etc/fstab file for the partition that did not mount. Open an editor, copy and paste the contents of the /etc/fstab file here.

When you upgraded, did you format any partitions beisdes the '/' ( root partition )? Just a guess, 9.10 is using ext4 by default. So this may not match the fstype of the partiton(s) not mounting.

This problem is because the /(root) file system has file system corruption errors.

Identify the root file system device name using,

Depending on the output you get run a file system check on the partition. If it's a ext4 file system,

where /dev/sdaX is the / partition. If it's a ext3 file system then you need to run fsck.ext3 /dev/sdaX

what means of this: "Identify the root file system device name using"

bacy,

Here is what you were asked to do. I did it on my system, and am posting the results to show you how.

Open a konsole, and use the 'su' command to get root privileges.

You need the root password, you would set that up at install time. Then run the command 'fdisk -l' ( without the quotes ).

The ID field identifies the file system type. 83 is ext3. 82 is swap file system.

Once you know what partition number, and the file system, you run the command 'fsck.ext4 /dev/sdaX' This would be for ext4, the default for Ubuntu 9.10. You need to use the correct partition number, my system has sda1 and sda6. Yours will have possibly the same, or different depending on the types of harddrives, and the partitioning scheme you have.

Hope this makes it easier to follow.

Use the fdisk -l command to find out which partition has the / mount point, and then run the fsck command on that partition.

I get this message, too, after rebooting.

I did fdisk -l

Mine shows that Linus is on dev/sda1 (boot) and dev/sda5

I typed fsck.ext4/dev/sda1
and got bash: fsck.ext4/dev/sda1: No such file or directory

I get the same when I try sda5

You have to put a space after fsck.ext4 . That means in your case, the command would be,

hth

Ahhhh thank you. Well, I have reinstalled the whole system and it seems to be working so far (this is about install 10... so I'm not holding my breath). If it happens again, I will definitely do that. Thanks.
