LFS and GRUB problems

[Aleksandar Urosevic]

Hello

I use Slackware 9.1 and kernel 2.4.24. In last week I start building LFS
using kernel 2.6.2 on my Slackware box. This is my HDD layout:

/dev/hdb1 [primary 1, boot] 0x83 /boot   ext2   128 MB
/dev/hdb2 [primary 2]       0x83 /       ext2     4 GB
/dev/hdb3 [primary 3]       0x83 /usr    ext2    12 GB
/dev/hdb4 [extended]        0x05
/dev/hdb5 [logical]         0x83 /tmp    ext2     2 GB
/dev/hdb6 [logical]         0x83 /var    ext3     2 GB
/dev/hdb7 [logical]         0x82 swap    swap   512 MB
/dev/hdb8 [logical]         0x83 /home   ext2    33 GB
/dev/hdb9 [logical]         0x83 /arhiva ext2   66+ GB

I mount LFS hard disc in /mnt/lfs and chroot to it with

:~--- one line ---
chroot "$LFS" /usr/bin/env -i HOME=/root TERM="$TERM" PS1='\u:\w\$ '
PATH=/bin:/usr/bin:/sbin:/usr/sbin /bin/bash --login
:~--- /one line ---

Also, I create proper /dev/hd{a,b}* devices with mkdnod.

So, I wish to install GRUB in MBR of /dev/hdb. This is my
/boot/grub/menu.lst:

:~--- start of menu.lst ---
# Begin /boot/grub/menu.lst

# By default boot the first menu entry default 0

# Allow 30 seconds bfore booting the default timeout 30

# Use prettier colors
color green/black light-green/black

# The first entry for LFS
title LFS SVN-20041017
root (hd1,0)
kernel (hd1,0)/lfskernel-2.6.8.1 root=/dev/hdb2

# Old Slackware
title Slackware 2.4.24 LAN
root (hd0,8)
kernel (hd0,8)/vmlinuz-2.4.24_LAN root=/dev/hda9

# End /boot/grub/menu.lst
:~--- end of menu.lst ---

And fstab on chrooted system:

:~--- start of fstab ---
# Begin /etc/fstab

# system   mount-point   fs-type   options           dump fsck-ord
/dev/hdb2  /             ext2      defaults          1    1
/dev/hdb1  /boot         ext2      defaults          1    1
/dev/hdb3  /usr          ext2      defaults          1    2
/dev/hdb4  /tmp          ext2      defaults          1    2
/dev/hdb6  /var          ext3      defaults          1    2
/dev/hdb8  /home         ext2      defaults          1    2
/dev/hdb9  /arhiva       ext2      users,owner,exec  1    2
/dev/cdrom /mnt/cdrom    iso9660   noauto,owner,ro,unhide,user  0  0
/dev/sda1  /mnt/camera   vfat      noauto,owner,user,unhide     0  0
/dev/hdb7  swap          swap      pri=1             0    0
proc       /proc         proc      defaults          0    0
sysfs      /sys          sysfs     defaults          0    0
devpts     /dev/pts      devpts    gid=4,mode=620    0    0
shm        /dev/shm      tmpfs     defaults          0    0
usbfs      /proc/bus/usb usbfs     devgid=14,devmode=0660       0  0

#End /etc/fstab
:~--- end of fstab ---

I build in kernel 2.6.8.1 for LFS support for EXT2, EXT3 and REISERFS
filesystems. I install grub in this way:

:~--- start grub install ---
# grub-install --no-floppy --recheck /dev/hdb
# grub

And then in grub shell:

> root (hd1,0)
> setup (hd1)
 Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1"
 exists... yes Checking if "/grub/stage2" exists... yes Checking if
 "/grub/e2fs_stage1_5" exists... yes

Running "embed /grub/e2fs_stage1_5 (hd1)"... 16 sectors are embedded.
succeeded
Running "install /grub/stage1 (hd1) (hd1)1+16 p (hd1,0)/grub/stage2
/grub/menu.lst"... succeeded
Done.
:~--- end grub install ---

Then I reboot box and get FS problem after chosing item 'LFS
SVN-20041017' from GRUB bootmenu:

Booting 'LFS SVN-20041017'
root (hd1,0)
 Filesystem type unknown, partition type 0x83
kernel (1,0)/lfskernel-2.6.8.1 root=/dev/hdb2
 Error 17: Cannot mount selected partition

When I chose 'Slackware 2.4.24 LAN' item I get only that Filesystem type is
ext2fs and also error 17, but FS for /dev/hda9 is ReiserFS.

I not understand, where I make mistake when installing and configuring
GRUB? Please help me. I wish to boot LFS from primary slave (hdb) when
Chose HDD1 as first boot device in BIOS, until not build complet BLFS and
tune up LFS box. But, how to do this GRUB tweak? :)

TIA
