Hi -

Thank you for opening a new thread, but you already got some good advice here.

SUGGESTIONS:
1. Find your original install CD/DVD, boot from it, and go into "rescue mode". Rescue mode should allow you to run "fsck".

2. This sounds like a production system. I would imagine you have an administrator. Find him or her - they should be able to help.

3. Failing all else, please refer to the links cited in your other post.

Good luck .. PSM

Hi,

It's nice that you opened a thread for the problem.

All you need to do is boot the machine with the install CD/DVD media then after login do a fsck on the filesystem;

Quote:

excerpt from 'man fsck';
NAME
fsck - check and repair a Linux file system
SYNOPSIS
fsck [ -sAVRTNP ] [ -C fd ] [ -t fstype ] [filesys ... ] [--] [ fs-specific-options ]
DESCRIPTION
fsck is used to check and optionally repair one or more Linux file systems. filesys can be a device name (e.g. /dev/hdc1, /dev/sdb2), a mount point (e.g. /, /usr, /home), or an ext2 label or UUID specifier (e.g. UUID=8868abf6-88c5-4a83-98b8-bfc24057f7bd or LABEL=root). Normally, the fsck program will try to run filesystems on different physical disk drives in parallel to reduce total amount time to check all of the filesystems.

If no filesystems are specified on the command line, and the -A option is not specified, fsck will default to checking filesystems in /etc/fstab serial. This is equivalent to the -As options.

The exit code returned by fsck is the sum of the following conditions:
0 - No errors
1 - File system errors corrected
2 - System should be rebooted
4 - File system errors left uncorrected
8 - Operational error
16 - Usage or syntax error
32 - Fsck canceled by user request
128 - Shared library error
The exit code returned when multiple file systems are checked is the bit-wise OR of the exit codes for each file system that is checked.

In actuality, fsck is simply a front-end for the various file system checkers (fsck.fstype) available under Linux. The file system-specific checker is searched for in /sbin first, then in /etc/fs and /etc, and finally in the directories listed in the PATH environment variable. Please see the file system-specific checker manual pages for further details.

Rute Tutorial & Exposition has 'fsck' section that is a good description. BTW, if your admin doesn't understand 'fsck' for GNU/Linux then I would be looking at getting a good GNU/Linux admin.

sorry for asking a lot but i am new to linux and you are the only one who help me.
the exact message i get is :
Couldn’t find matching filesystem: LABEL=/common
Give root password for maintenance
(or type control-D for normal startup)

i understood the fsck but i am confused with the parameters can you help me to get the exact command needed in my case?
thanks again

Hi,

19.5 File System Repair: fsck of 'Rute' should give you some insight. I cannot give you a better example as that's the simplest.

You should use a install CD or LiveCD to boot then do the filesystem maintenance.

hi again
thanks again for your help
yes i understood that i have to boot from the cd and to run fsck
what i am asking is that the message that i got is couldn't find matching filesystem: LABEL=/common
to repair it the following is correct?
what i understand is
1)boot from cd
2)fsck -a -t ext2 /dev/hda1

true? thanks again and again

I have a way to fix a complication in your problem -- The missing root password.

What you need is a PS\2 keyboard first.

1. Plug PS\2 keyboard in if not already done so
2. Start the computer. At the boot loader prompt, add the option init=/bin/bash
3. A BASH shell will be started without request for root password or filesystem check
4. Type passwd to change the root password.
5. Reboot to get a normal boot, PS\2 keyboard no longer needed in regular boot.

My password in openSUSE 11.2 went corrupt within the last week and I used this remedy to fix it. I have suggested to others twice.
