Grub Error Collection [Part 1001]

[mr_hades]

Hi
need some help with the installation

I've got at first boot:

"Booting 'Gentoo Linux 2.6.14-gentoo-r5'

root (hd0,0)
Filesystem Type is ext2fs, partition type 0x83
kernel /boot/kernel-genkernel-x86_64-2.6.14-gentoo-r5 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/hda3 udev
[Linux-bzImage, setup=0x1e00, size=0x23ca50]

[Linux-initrd @ 0xbfdc9000, 0x186559 bytes]

Error 28: Selected item cannot fit into memory
Press any key....."

I use GNU GRUB version 0.96 (631k lower / 3144064K upper memory)
and my grub.conf is :

default 0
timeout 30
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title=Gentoo Linux 2.6.14-r5
root (hd0,0)

initrd /boot/initramfs-genkernel-x86_64-2.6.14-gentoo-r5

I have 4 partitions:

/dev/hda1 /boot 100M ext2
/dev/hda2 swap 3GB
/dev/hda3 / 20GB ext3
/dev/hda4 /home 50GB ext3

and the hardware: 1xAMD Opteron and 3GB ram

any ideas ??

thx

I believe I read somewhere on these forums that specific versions of grub had problems with large amounts of memory. The solution was to unmask and install a newer version of grub. You could try grub-0.97 or higher.

hi i get same problem i instaled gentoo from live DVD i get 3gb of ram
u say problem solved but how i put all that ?

[Arnaudv6]

Good afternoon everyone !
I'm new user to Gentoo. I just compiled my new system, alongside my ubuntu :p
the matter is I already have grub installed on ubuntu's root, and thus, during Gentoo's install,
I skipped all the "installation of grub" section, Am I clear anough ?
So I've got a kernel image in /boot on Gentoo's partition, but my grub doesn't want to start it

I must confess I made a search, but didn't read the 700 posts of this topic...
I'm sure someone will help me even if I'm a bad user ?
Thanks a lot !

Arnaudv6,

Welcome to Gentoo.

Some error messages, if you get any, when you try to start Gentoo would be useful.
You have ubuntu installed and added Gentoo beside it.
If you did not make a separate Gentoo boot partition then root (hd0,5) in your grub.conf is correct
If Gentoo has a separate boot partition then that root (hd0, ...) needs to point to it.

We need to know your hard drive partition layout, from

Code: Select all

fdisk -l

and what each partition is used for.
Error messages are also very useful

[Arnaudv6]

Dumno if it can help :

Error 2: Bad file or directory type

and it works no more if I erase the "ro" option endiig my kernel line...
thanks for helping !
We posted the same time, NeddySeagoon : I'm on : wait for me please !

[NeddySeagoon]

Arnaudv6,

The output of

Code: Select all

ls -l /boot

for your Gentoo /boot may help too

[Arnaudv6]

/boot has no dedicated partition... thanks !

NeddySeagoon, I must leave for about 7 hours...
won't read anymore until.
Thanks for what you already done and the way you still search

[NeddySeagoon]

Arnaudv6,

The /boot you shows was not for gentoo as its kernel is not there but this

Code: Select all

arnaud@arnaud-laptop:~$ sudo mount /dev/sda6 /media/gentoo/
arnaud@arnaud-laptop:~$ ls -l /media/gentoo/boot/

is interesting, and the listing that follows.

That shows your kernel name is kernel2.6.25-gentoo-r5 and its in (hd0,5)/boot, which matches your grub.conf.

Grub works by reading the boot filesystem. As there is not much space for grub, you have to choose the boot filesystem type at grub install time and it can only read one filesystem type.
That means that (hd0,0) and (hd0,5) must both be the same file system type or grub cannot read (hd0,5). For grub, ext2=ext3.
The way around this is to put your Gentoo kernel into your ubuntu /boot so everything it needs to read is in (hd0,0)

[Arnaudv6]

Thanks NeddySeagoon ! .... then :

The /boot you shows was not for gentoo as its kernel is not there

what what what ? my kernel image of gentoo shouldn't be just in /boot on this partition ?
(I typed this command line from my ubuntu... sure you understood !?!

Grub works by reading the boot filesystem. As there is not much space for grub, you have to choose the boot filesystem type at grub install time and it can only read one filesystem type.
That means that (hd0,0) and (hd0,5) must both be the same file system type or grub cannot read (hd0,5). For grub, ext2=ext3.

But they are same system files ! 83 Id type, no ?
I've got no grub file or directory on that partition : does it matter ?

The way around this is to put your Gentoo kernel into your ubuntu /boot so everything it needs to read is in (hd0,0)

You mean I can put the kernel image on ubuntu partition, giving it gentoo's one as root partition ?

Thanks a lot for your answers !
Arnaudv6

[desultory]

You mean I can put the kernel image on ubuntu partition, giving it gentoo's one as root partition ?

Indeed.

[Arnaudv6]

Thanks desultory !
I try it now !

root		(hd0,0)
kernel		/boot/kernel2.6.25-gentoo-r5 root=/dev/sda6
#System.map-genkernel-x86-2.6.24-gentoo-r5

Then is there no mean to boot a kernel image from my Gentoo ext3 part directly ?
That seems no such complicated, and would be great... thanks a lot !
Arnaudv6

[NeddySeagoon]

Arnaudv6,

Post your

Code: Select all

fdisk -l

and tell us what fie system type is on each partition.
The partition type byte, in fdisk, means almost nothing.

If your ubuntu uses ext2 or ext3 then grub will be able to read Gentoos ext2 and ext3 filesystems too,
However, if your ubuntu install uses rieserfs or anything other than ext2 or ext3, you have a problem.

When you know you want to install several distros, in advance of the first install, its normal to make a separate /boot partition to contain *all* the kernels, this gets around the single file system type for Grub.

[Arnaudv6]

I don't like so much having gentoo's kernel on ubuntu's partition, but it works...
Thanks for your tip about a dedicated partition for /boot : I'll do this soon

Grub works, but my kernel panics at trying to mount root fs.
it claims "unknown block(2,0)
I know the interresting thing are precedent steps, but I can't use scrolling...
and there is nothing revealant left on screen after crashing...

Arnaudv6

[NeddySeagoon]

Arnaudv6,

Code: Select all

unknown block(2,0) 

is the interesting bit in this case.

Code: Select all

less /usr/src/linux/Documentation/devices.txt

tells that its your floppy drive.

This means the kernel cannot communicate with your hard drive controller, nomally because some options are missing or are set to <M> when they need to be <*>.

We need your

Code: Select all

lspci

output to help you fix that.

Still haven't found the solution, maybe is it related to initrd ?
http://bbs.archlinux.org/viewtopic.php?id=47357
Arnaudv6

[NeddySeagoon]

Arnaudv6,

You don't have any IDE drives any more with the kernel settings I gave you, thats devices like hda.
You should have the IDE kernel branch disabled

Code: Select all

< > ATA/ATAPI/MFM/RLL support  ---> 

All your drives will be sdX for hard drives or sr for CDROMs.

Either you did not build the kernel the way I suggested or you didn't install it into boot properly, so you are still using an old kernel.

Notice your kernel line in grub.conf says

Code: Select all

kernel      (hd0,0)/boot/kernel2.6.25-gentoo-r5 root=/dev/sda6 

Notice the sda6. That means that you are telling the kernel you are using the SCSI layer for your hard drive.
Now look at your error image again ... it says hda.
Maybe changing /dev/sda6 to /dev/hda6 in your grub.conf will allow you to boot.

Its not an initrd problem as your grub.conf line does not invoke an initrd. Even if you have one and load it in grub.conf, its not being used.

I didn't know I had a wikipedia profile ... I'll need to read it
