Hey guys,
I'm having this weird problem again, me and VFS don't seem to like eachother, i'm sorry to bother you again, but everything again seems right. I'm have Lilo installed as my bootloader, my root partition is /dev/hda3 and my boot partition is /dev/hda1. My root partition is Ext3, the boot is Ext2 both are compiled in to the kernel. It are just very normal IDE drives, nothing special, the only thing is that it is a 320 Gig drive but that shouldn't be a problem right, the root patition is just 20 Gig of size.
Anyway, when booting i'm getting serverd with the following error:

Kernel panic - not syncing: VFS: unable to mount root fs on unkown block (3,3)

What can be the problem?
Thx in advance!

At this very moment I'm having even a bigger problem, when I reboot do the whole chroot process and then try tu emerge grub (I unmerged lilo, just as a test), i get the following error, even if I emerge lilo again:

!!! ERROR: sys-boot/lilo-22.7 failed.
Call stack:
ebuild.sh, line 1539: Called dyn_unpack
ebuild.sh, line 712: Called die

!!! IO Failure -- Failed 'touch .unpacked' in /var/tmp/portage/lilo-22.7
!!! If you need support, post the topmost build error, and the call stack if relevant.

Don't really know how i caused that?!

I'm getting the same error with grub, maybe I need to pass the hda=stroke option or something like that? Because the bios thinks the drive is 137 Gig but it is 320. Tough fdisk from the live cd sees it is 320Gig...

First, then you should update the mainbaord Bios.
Please post /boot/grub/menu.lst and /etc/fstab.

Fstab :
Quote:

/dev/hda1 /boot ext2 noauto,noatime 1 2
/dev/hda3 / ext3 noatime 0 1
/dev/hda2 none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,ro 0 0


/boot/grub/menu.lst:
Quote:

# Which listing to boot as default. 0 is the first, 1 the second etc.
default 0
# How many seconds to wait before the default listing is booted.
timeout 30
# Nice, fat splash-image to spice things up :)
# Comment out if you don't have a graphics card installed
#splashimage=(hd0,0)/boot/grub/splash.xpm.gz

title=Gentoo Linux 2.6.17-r5
# Partition where the kernel image (or operating system) is located
root (hd0,0)
kernel /boot/kernel29092006 root=/dev/hda3

title=Gentoo Linux 2.6.17-r5 (rescue)
# Partition where the kernel image (or operating system) is located
root (hd0,0)
kernel /boot/kernel29092006 root=/dev/hda3 init=/bin/bb

I guess there are no updates for my BIOS but that is not a real problem is it?

while I dont know how to solve your problem, I noticed that it appears that your rescue kernel is the same as your main one....

[edit] just thought about it, hehe. if you dont have a working kernel in the first place you cant have a rescue one. I just assumed it was an error when it could just be a placeholder....sorry[/edit]

try recompiling the kernel with support for ALL file systems built in (not as modules)
i was having teh same issue as you untill i did that. eventually i'll start removing each one, one-by-one untill my system breaks, just to track the guilty one down, but right now im happy with a working sledgehammer :)

Okay, that to is a way, tough I have support for all needed file systems in the kernel but I will try this...

Hmm, buidling in all the filesystems is not the solution, probably it's something with chipset support or something like that? I don't know what to do anymore, and I'm kind of panicing because this server needs to be back up as quickly as possible :( ...

Hmm, I'm starting to think it's this good old one again.
And of course, my other server has the same board so I allready encountred the problem once, and offcourse Neddy solved it for me, and ofcourse I forgot to check. Any how here is my old problem, I'm hoping the same solution is gonna work.
