Kernel Panic on boot system

kacperix · #1 18th January 2007, 04:49 PM

Hi everybody. I know that this was bringing up question many times, but I still don't know how resolve it.

When I want select my Fedora system from GRUB's list and press ENTER, then I'v got this error:

Code:

Reading all physical volumes: This make take a while...
    No volume groups found
    Volume group "VolGroup00" not found
Unable to access resume device (/dev/VolGroup00/LogVol00)

setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
Kerenl panic - not syncing: Attempted to kill init!

What I must do to resolve this problem?? I really want working on Fedora, but this problem more and more discourage me :/

How did this get renamed: VolFroup00 (should be VolGroup00) - also, why is it looking for LogVol01 when it should be LogVol00? Did you tweak something?

No, no...that's only clerical error. I must wrote this by hand

I was correcting this.

***bob*** · #4 18th January 2007, 05:38 PM

Well, how about the grub.conf? Notice that there's a space between (hd0 and 2) -it should be booting (hd0,2) instead of (hd0, 2). Can you stop the boot at the menu and then test by 'e' for edit on the appropriate line, 'enter' to make changes, 'enter' again to save the change and 'b' to boot? The error's also the same at (hd0,0) for Windows, BTW.

kacperix · #5 18th January 2007, 05:45 PM

There are no spaces between this to numbers.

But this problem is no always. Now I write this post from LINUX OS, but for example, when I Turn On my computer then this problem is and then I must restart many times my machine then it to start. Or when I want start LINUX after shutdown Windows OS.

You may have a hard drive problem. I'd go to the manufacturer's site and check for tools to test the drive.

kacperix · #7 18th January 2007, 05:58 PM

I think my HDD is OK. I buy this machine a few weeks ago. Windows working on it good, and before I have Mandriva too, and all worked without problems. I have this problem since first time installed my Fedora, I try reinstalled it but this no help.

You have an fstab problem. Post your /etc/fstab and it should be an easy fix.

kacperix · #9 19th January 2007, 12:00 PM

#cat /etc/fstab

Code:

Okay, if I'm reading this corrently, partition /dev/sda3 is your boot partition and /dev/sda4 is your primary linux partition. Your fstab looks a little strange to me, however I don't use LVM.

1. You don't have a swap partition according to fdisk -l so you can comment out that line.

2. /dev/VolGroup00/LogVol00 doesn't make sense to me. I would try changing that. So your fstab should look something like this:

Code:

/dev/sda4               /                       ext3    defaults        1 1
/dev/sda3               /boot                   ext3    defaults        1 2
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
tmpfs                   /dev/shm                tmpfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
sysfs                   /sys                    sysfs   defaults        0 0
#/dev/VolGroup00/LogVol01 swap                    swap    defaults        0 0

Grub.conf

Code:

title Fedora Core (2.6.18-1.2869.fc6)
        root (hd0,2)
        kernel /vmlinuz-2.6.18-1.2869.fc6 ro root=/dev/sda4 rhgb quiet
        initrd /initrd-2.6.18-1.2869.fc6.img

Hi, I would like to help if I can.

There seems to be a problem with the partition you are trying to boot from.

your /boot/grub/grub.conf has the following:

Quote:

title Fedora Core (2.6.18-1.2869.fc6)
root (hd0,2)

..as fas as i'm aware this is the second partition of the first hard drive.

but output of fdisk -l says that you boot partition should be (0,3):

Quote:

/dev/sda2 1913 28617 214507912+ f W95 Ext'd (LBA)
/dev/sda3 28618 28630 104422+ 83 Linux

...this is the third partition on the first hard drive

The partition you appear to be trying to boot from is an extended parttiton ! if you can not boot into the OS to fix this. I would try booting from the installation disk and typing linux rescue, once you have mounted your OS edit grub so it is booting from the correct partition.

The output of fdisk -l on my FC6 install with LVM doesnot show a SWAP file either, however, I do have one, confirmed with system monitor. Not sure why it doesnt show with fdisk.

Grub.conf

Code:

title Fedora Core (2.6.18-1.2869.fc6)
        root (hd0,2)
        kernel /vmlinuz-2.6.18-1.2869.fc6 ro root=/dev/sda4 rhgb quiet
        initrd /initrd-2.6.18-1.2869.fc6.img

I was doing what you wrote here, but then system wan'ted start. I then was changin one thing: in grub.conf I didn't change anything, that's mean the line is:

kernel /vmlinuz-2.6.18-1.2869.fc6 ro root=/dev/VolGroup00/LogVol00 rhgb quiet

and in fstab file I commented this line what you say and since I do this all it's OK. My system boot without any problem

If sth will be wrong i write about this here. But now is OK

Hi everybody.

This problem return to me after install kmod-nvidia and the kernel was updating. My KERNEL now is 2.6.19-1.2895. Where is know the problem?? I will in near feature reinstall the system, maybe you have some propsitions how redistibute my disk partitions??

beissemj · #14 23rd January 2007, 03:00 PM

I believe installing kmod-nvidia / kmod-ati (or whatever it is called) reinstalls a FC6 kernel and changes your grub.conf. However, check grub.conf again and change your kernel line to reflect the updated kernel.

Code:

/vmlinuz-2.6-19-1.2895 ro root=... rhgb quiet

You shouldn't ever need to reinstall, unless you do something REALLY stupid, but even then it can usually be fixed with a liveCD. You can turn off LVM (I think) and repartition your drive with either fdisk /dev/pick_your_device or something like gparted/qtparted.
