Oooh! So Close!

Shockingly I have managed to implement a stage 3 Gentoo on one of my machines ... well ... very nearly!

I went through all the instructions, figured (finally) how to resolve the proxy issue got to the end, restarted, it got to grub, carried on and ....

I get he following line:

Kernel panic: VFS: Unable to mount root fs on 03:03

I figure it's either a typo somewhere on my part or something to do with the way Gento mounts it's partitions ... I'm opting for user error as I figure Gentoo should have a clue about what they're up to :-)

Any ideas?

First thing that comes to mind is the /etc/fstab files... what does yours look like?

either that or root is set to the wrong partition in grub

Hi,

I edited both /etc/fstab and /boot/grub/menu.lst to be be as close to the examples as possible ... in the latters case almost exactly.

I don't think it's grub because the system does exactly what I'd expect but it might be fstab ... how do I check the files if I can't get past this point?

I suppose that I maight not have included everything I was supposed to when I did make menuconfig (it's a possibility I suppose).

Thanks for your help :-)

You might try reading through this thread/tip. Basically, boot from the install CD and mount your partition with /etc (usually /). If it is obvious, fix the error, if not, post the information here. Also, it couldn't hurt to mention your Grub menu.lst file (/boot/grub/menu.lst).

Some details on what you actually used for your file systems would also be some help! You are correct in also suspecting your kernel config. If you used ReiserFS or XFS and you did not compile support into your kernel for them you would certainly be having trouble. Once you boot with the CD and go in to check your fstab and menu.lst files you can also go back to /usr/src/linux and make menuconfig to go in and look at what you chose. If you do NOT have support in your kernel for your FileSystem of choice then you need to compile it in and replace your existing kernel with the new one (that should actually work!)

Hope that helps!

Hi,

Here are my grub & fstab files:

Grub Menu (/boot/grub/menu.lst)

Did you enable XFS support in the kernel built-in rather than as a module?

XFS? Not specifically, at least I don't think so!

I'm trying to recompile the kernel now ... how much more of the procedure do I need to do once I'd done it?

Not sure what you mean... After you build the kernel, you would have to mount boot, copy bzImage over and reboot. I guess you don't really need to save the old kernel since it does not work.

Hi Naan,

What I meant was that, in the instructions, there are a number of other "final" steps that have to be done. Some of these are text file edits and I would have guessed that they didn't need to be redone but I was specifically wondering about the series of "emerge" commands (I don't know if they need to be done again after kernel recompilation? However I'm guessing from your last reply that I don't ...

Thanks

Correct all you need to do is replace your bad kernel with your new shiney (working?) kernel and then reboot.

Hope that helps!

I had exactly the same problem the other day your have to edit your kernel line in your menu.lst.
Change the root partition to the good one (if its /dev/hda3 in your partition table its /dev/hda3 in grub for that part) but i am sure hda3 is not your root partition since you get that error

hope it works

Its not a problem whit your old kernel.

VampyreUK: Are you positive you set up your /etc/fstab correctly? If it is, then your menu.lst file should be accurate.

root(0,0) refers to where /boot is. 1st drive, 1st partition. /dev/hda1 should be accurate.
root=/dev/hda3 points to your / filesystem.

As your /etc/fstab indicates, those are true, if that is how your partitions actually are.
