[gentoo-user] [OT] GRUB won't boot my new Gentoo install

[gentoo-user] [OT] GRUB won't boot my new Gentoo install

[Dan Johansson]

[-- Attachment #1: Type: text/plain, Size: 1612 bytes --]

Hi,

At the moment I'm trying to upgrade one of my old computers from SuSE to 
Gentoo. I have install a second SCSI-disk and installed Gentoo on this second 
disk using a stage-1 install. But when I try to boot my new install GRUB 
hangs (kernel does not uncompress) after I have selected the kernel.

This is the output from grub after selecting my gentoo setup.

root (hd1,2)
	Filesystem type is ext2fs partition type 0x83
kernel /kernel-2.6.12-r6 root=/dev/sdb2 acpi=off
	[Linux-bzImage, setup=0x1200, size=0x165a46]
(and here it hangs....)

I have installed grub to MBR of the first SCSI-disk (sda) and I'm having my 
grub files on sdb3.

Here's my grub.conf file:

# By default, boot the first entry.
default 0

# By default boot the old SuSE (until Gentoo boots OK)
title SuSE
    kernel (hd0,1)/boot/vmlinuz root=/dev/sda2   acpi=off splash=silent 
showopts
    initrd (hd0,1)/boot/initrd

# For booting Gentoo 2.6.12-r6
title  Gentoo 2.6.12-r6
root (hd1,2)
kernel /kernel-2.6.12-r6 root=/dev/sdb2 acpi=off

The second SCSI-disk (Gentoo) has the following partitions:
/dev/sdb1	swap
/dev/sdb2	/
/dev/sdb3	/boot
/dev/sdb4	LVM

The Kernel is compiled without Module support and all necessary drivers are 
compiled into the kernel.

Booting the old SuSE installation works without problems but Gentoo does not.
Any suggestions on what could be wrong?

Regards,

Add "doscsi" to the kenel options.

Not without knowing at what point the boot fails.

What is the error you're getting, and at what point after selecting the
Gentoo entry?

Secondly, you have only one separate boot partition? Meaning that the
SuSE /boot folder is on the SuSE partition?

That might be your problem-- since that would mean that you've got
possibly two installs of GRUB (one in the SuSE /boot folder and one in
the Gentoo /boot partition).

So you've got to wonder which one is running. At least I did.

I also dual-boot SuSE and Gentoo (SuSE is my fallback in case I break
Gentoo so badly that I need to use something else to fix it), and what I
did (since I 'really' use the Gentoo GRUB, and the Gentoo /boot
partition) was to copy the SuSE kernel (and System Map, and config) to
my Gentoo /boot folder.

Perhaps you need to do that in reverse (copy the compiled kernel and
related files to your SuSE /boot folder).

HTH,
Holly

Have you tried grub's map command? $info grub has
detailed instructions.

For the Gentoo installation /boot is on it's own partition, for the SuSE /boot 
is on the / partition.

Yes there are two installs of GRUB but only the Gentoo one is used. I can see 
that on the release numbers (Gentoo 0.96, SuSE 0.93) and that the right 
grub.conf (menu.lst) is shown when I boot (Only the Gentoo one has entries 
for Gentoo).

I don't think this should be necessary as GRUB do find the file containing the 
kernel.

I've also tried the doscsi boot option as suggested in an other reply but this 
did not help.

A few things look odd to me:

1. Isn't (hd1,2) the same device as /dev/sdb2?  It looks like your /boot 
and / are the same here...
2. The normal name for the kernel is "vmlinuz-...".  You have "kernel-..."

So, which partition actually contains /boot?

How are you switching between grub versions?  Important: if you are 
changing the disk boot order in the BIOS, you need to remember that grub 
always defines (hd0) as the currently booting drive...regardless of the 
order of the drives in the system.  So you may need to change everything 
to be (hd0,X).

Can you get to a grub command line, and do a  "find /kernel-2.6.12-r6"?

No, (hd1,2) is /dev/sdb3 (grub start counting from 0).

> 2. The normal name for the kernel is "vmlinuz-...".  You have "kernel-..."
/boot/kernel-2.6.12-r6 is a cp -a from /usr/src/linux/arci/i386/boot/bzImage, 
and /usr/src/linux is a link to /usr/src/linux-2.6.12-gentoo-r6

> So, which partition actually contains /boot?
For Gentoo (hd1,2) /dev/sdb3
For SuSE (hd0,1)/boot /dev/sda2/boot

I'm not switching between grub versions, I only use the grub from Gentoo (the 
SuSE grub is not being used). I've also tried to change the boot order of the 
disks in BIOS (and changing the (hdx,y) references in grub) with the same 
result.

Yes, grub finds the file.

Ok.  everything looks sane to me.  What are the starting/ending sectors 
for /dev/sdb3?  (fdisk -l -u).  Some systems still have trouble 
accessing sectors past about 8GB through BIOS calls.

No problem...

Disk /dev/sdb: 4335 MB, 4335206400 bytes
255 heads, 63 sectors/track, 527 cylinders, total 8467200 sectors
Units = sectors of 1 * 512 = 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/sdb1            63    498014    248976   82  Linux swap
/dev/sdb2        498015    706859    104422+  83  Linux
/dev/sdb3        706860    819314     56227+  83  Linux
/dev/sdb4        819315   8466254   3823470   8e  Linux LVM

As you see its installed on a quite small disk (4GB) so the 8GB limit should 
not be a problem in this case.

I'm starting to think it's the kernel it self that is having a problem (miss 
configuration) so I'm playing around with the kernel configuration at the 
moment.

As I suspected, this was not a problem with GRUB, but with my brain.
I had compiled the kernel with ProcessorFamily=Pentium4, and this machine only 
have a PII processor. After selecting ProcessorFamily=i586 the Gentoo system 
boots OK. Sorry for the trouble and thanks for all suggestions.
