Linux will not start

ShayA · 10-25-2006, 04:40 PM

I am newbie with Linux.

I did a terrible mistake and I hope it can be fixed easily without losing any data.

I installed FC5 and worked with it for few months.

I have the last kernel 2.6.18

I have an IDE HD (hdc1)

Few days ago I've installed a new SATA HD (I think marked as hds1).
I've created a new partition, a new logical volume and mount it. I set the mounting point to "/" ;(

The day after when I try to open the computer, the Linux boot halt at the middle with some errors "...FC5 cannot touch /var/lock/subsys/kudzu Read-only".

I tried to use the DVD in order to "upgrade" the OS. At some point I've got that its cannot find the "/" and I might have a problem with the stable file.

I am almost sure that I need to remove the new mounting point in order to make it work.

Can someone help me with that. I have no idea what to do.
Please write the required steps in detail.

Many thanks,
Shay

Just try it out with a live cd and edit your fstab. This might help you.

I used the installation DVD in order to get to rescue mode.
I could not find the fstab file at /etc/fstab

Mount the partition where you have your linux installed. chroot to the partition and then edit the fstab.

After you have booted with the help of the live, open a terminal and go to the root prompt. Do a fdisk -l, which will list all the partitions. Mount the partitions using the mount command. chroot to the patition where you have your / partition. As an example,

Code:

root@foobar:~$ fdisk -l

Disk /dev/hda: 255 heads, 63 sectors, 4870 cylinders
Units = cylinders of 16065 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hda1   *         1      4839  38869236   83  Linux
/dev/hda2          4840      4870    249007+   5  Extended
/dev/hda5          4840      4870    248976   82  Linux swap

root@foobar:~# mkdir /tmp/hda1
root@foobar:~# mount -t ext3 /dev/hda1 /tmp/hda1
root@foobar:~# cd /tmp/hda1
root@foobar:~# chroot .
root@tty[/]# nano etc/fstab

I hope that helps you.

I followed your instructions.
However, when I type chroot I get

Quote:

cannot run command '/bin/bash':no such file or directory.

What I am doing wrong?

ShayA · 10-27-2006, 03:07 AM

Anyone?
Please.....

copy the output of your fdisk -l here so we can see what you have got

then if you can see /etc/fstab when you have mounted the drive copy the output of that to here

(use cat /etc/fstab to view the contents

ShayA · 10-27-2006, 03:31 AM

This is what I get:

Code:

 
Disk /dev/hdc: 41.1 GB, 41174138880 bytes
255 heads, 63 sectors/track, 5005 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hdc1   *           1          13      104391   83  Linux

root@slax:~#
root@slax:~#

Under hdc1 I dont see the fstab.
I see the grub folder.

dasy2k1 · 10-27-2006, 03:35 AM

mount hdc1 and post a ls -lh of /

ShayA · 10-27-2006, 03:41 AM

BTW, you don't see the SATA HD because the I have a mother board chip that required kernel 2.6.18 to support it.
The live CD has an older kernel version.
In any case the OS was installed on the first HD (IDE)

ShayA · 10-27-2006, 06:44 AM

Still looking for your help.
Pleas....

dasy2k1 · 10-27-2006, 08:28 AM

how many sub partitions have you got in the LVM partition /dev/hdc2?

ShayA · 10-27-2006, 08:35 AM

I guess some...
How can I see that.
The hdc2 is not mount (I dont know how to mount LVM)
