 Posted: Wed Nov 03, 2004 11:37 pm Post subject: nOOb need help with Kernel panic - not syncing: VFS: Unable |
 |
|
Sorry guys. Im very computer literate and serve currently for the gov't (CACI) as a network security analyst. however im completely new to the unix /linux community. i was told this is the best place to start.
the problem im having is this:
| Code: | | Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(1,0) |
I have no idea what to use to check my fstab or grub.conf
i noticed people were checking those but when i boot from the cd and type modprobe ide-disk i still cannot get into any of these config files. Please help.... once again sorry for the nOOb questions

That message is telling you that it is trying to mount /dev/hdb as you rroot file system. To get in and look at what you have or to post them | Code: |
boot install cd
mount /dev/hd?? /mnt/gentoo ( your root partion. If your not sure fdisk -l will list your disk and partions)
cd /mnt/gentoo
mount /dev/hd?? boot
cat etc/fstab ( or use nano)
cat boot/grub/grub.conf ( or use nano) |

ok /etc/fstab is completely empty
boot/grub/grub.conf contains the following:
| Code: | default 0
timeout 30
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.9
root (hd0,0)
kernel /kernel-2.6.9-gentoo-r1 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda3
initrd /initrd-2.6.9-gentoo-r1 |
just to give you a idea of my current system:
80 gig maxtor drive ATA
amd 3200+ 64 bit
1 gig ddr ram
abit kav-max3 mobo

1 I was wroug about "unknown-block(1,0)" being "hdb". That would be 4,0 and 3,3 is hda3.
2 you need an fstab  You can use nano now to fill it out. As a model look at this thread he has a simular prob Cannot mount /
Ill be back.

When you mounted /mnt/gentoo do a " ls " which is shoule show something like | Code: | ls /mnt/gentoo
bin/ dev/ home/ lost+found/ opt/ root/ stage1-x86-2004.2.tar.bz2 tmp/ var/
boot/ etc/ lib/ mnt/ proc/ sbin/ sys/ |

ok my /etc/fstab says the following:
| Code: | # /etc/fstab: static file system information.
# $Header: /home/cvsroot/gentoo-src/rc-scripts/etc/fstab,v 1.14 2003/10/13 20:03:38 azarah Exp $
#
#noatime turns off atimes for increased performance (atimes normally aren't
#needed; notail increases performance of ReiserFS (at the expnese of storage efficiency). It's safe to drop the noatime options if you want and to
#switch between notail and tail freely.
# <fs> <mountpoint> <type> <opts> <dump/pass>
# Note: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/BOOT /boot ext2 noauto,noatime 1 1
/dev/ROOT / xfs noatime 0 0
/dev/SWAP none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0
# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
# Adding the following line to /etc/fstab should take care of this:
none /dev/shm tmpfs defaults 0 0 |
___________________________________________________________
Grub is as followed:
| Code: | default 0
timeout 30
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux 2.6.9
root (hd0,0)
kernel (hd0,0/boot/kernel-2.6.9-gentoo-r1 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda3
initrd (hd0,0)/boot/initrd-2.6.9-gentoo-r1 |
__________________________________________________________
I hope this helps.. PLZ assist.

Your fstab is wrong. You have to edit it. Heres mine as a example | Code: | grep -v "#" /etc/fstab
/dev/hda1 /boot ext2 noauto,defaults 1 1
/dev/hda3 / ext3 defaults 0 2
/dev/hda2 none swap sw 0 0
/dev/hda5 /usr ext3 defaults 0 2
/dev/hda6 /home ext3 defaults 0 2
/dev/hda7 /opt ext3 defaults 0 0
/dev/hda8 /home/cifs reiserfs notail,defaults 0 2
/dev/hdc /mnt/cdrom iso9660 noauto,ro,users 0 0
/dev/fd0 /mnt/floppy vfat noauto,users,rw 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
none /sys sysfs defaults 0 0
none /dev/pts devpts defaults 0 0 |
You have edit out /dev/BOOT and suck put in your partions and fs type.
Your kernel line has a misstype
kernel (hd0,0/boot/kernel-2.6.9-gentoo-r1
initrd (hd0,0)/boot/initrd-2.6.9-gentoo-r1
should be
kernel (hd0,0)/kernel........
initrd (hd0,0)/initrrd........

One thing I notice is that the commands that are confusing you are potentially different.
| Code: | | # nano -w /etc/fstab |
allows you to edit the file /etc/fstab in nano.
shows the contents of the file ./etc/fstab, where . is the current directory. So if your current directory is /var/foo/bar, the file that this command displays is /var/foo/bar/etc/fstab, not /etc/fstab.
To figure out what directory you're in, use
To check that you're making changes to the correct file, once you've edited fstab with nano, type
Sorry if this is all stuff you know! Seems like you might be a bit confused though; hope this helps.
