trouble with grub

[wriggles]

I have several os's installed
win xp, 98 and rh 8.0 on hda (hard drive one)
and just yesterday rh fedora core 1 on hdb (second hd).
As part of the Fedora installation i chose not to reinstall grub (I already have it installed( i have 2 rh 8.0 kernel running and didnt want to mess up these!). I assumed configuring grub would be easy!
I installed fedora and tried to configure grub to boot with no joy.
My old grub.conf file
default=2
timeout=10
splashimage=(hd0,6)/grub/splash.xpm.gz
title Red Hat Linux (2.4.20-28.
root (hd0,6)
kernel /vmlinuz-2.4.20-28.8 ro root=LABEL=/ hda=ide-scsi
initrd /initrd-2.4.20-28.8.img
title Red Hat Linux (2.4.18-14)
root (hd0,6)
kernel /vmlinuz-2.4.18-14 ro root=LABEL=/ hda=ide-scsi
initrd /initrd-2.4.18-14.img
title DOS
rootnoverify (hd0,0)
chainloader +1


I thought adding the following would be OK -
title Fedora Core 1 (2.4.22-1.2115.nptl)
root (hd1,0)
kernel /vmlinuz-2.4.22-1.2115.nptl ro root=LABEL=/ hdb=ide-scsi
initrd /initrd-2.4.22-1.2115.nptl.img


be this causes problems.

My hw browser gives the following for what is installed

/dev/hde
hde1 win98
hde2 extended
hde5 ntfs
hde6 ntfs
hde7 ext3 /*/boot for the two rh 8.0 kernels */
hde8 swap
hde9 ext3

Fedora on the other harddrive

/dev/hdg
hdg1 ext3
hdg2 swap
hdg3 exr3

both hard drives are on a raid controller(highpoint370) (raid is NOT configured)

What is the configuration required for my grub.conf file?
everything I try will not work!

[Dolda2000]

hde and hdg? In that case, it seems that you should try (hd2,0) instead of (hd1,0) in the GRUB config.

If that doesn't work, would you mind posting the exact error message?

[wriggles]

(hd2,0) does not work.
I ran dmesg for the failed boot and everything is fine (it all looks as it should - I'll post this if you request).
The problems start when red hat starts to load.

the following errors occur amoung successful items

modprobe: can't open dependencies file /lib/modules/2.4.22-1.2115.nptl/modules.dep (no such file or directory)

finding module dependencies: depmod: Can't open /lib/modules/2.4.22-1.2115.nptl/modules.dep for writing [FAILED]

Mounting local files systems: mount:fs type vfat not supported by kernel [FAILED]

modprobe: can't open dependencies file /lib/modules/2.4.22-1.2115.nptl/modules.dep (no such file or directory)

Checking for new hardwaremodprobe: modprobe: Can't open dependencies file /lib/modules/2.4.22-1.2115.nptl/modules.dep (no such file or directory)

this then occurs three times

modprobe: can't open dependencies file /lib/modules/2.4.22-1.2115.nptl/modules.dep (no such file or directory)

and a final failure

Mounting other filesystems: mount: fs type vfat not supported by the kernel [FAILED]


It then boots directly into RH8 with X slightly screwed.

[Dolda2000]

I see. That's not a problem with GRUB, though.

It seems that your module dependency database has been screwed up. What happens if you run "depmod -a" to regenerate it?

[wriggles]

ran depmod -a and get the following response

depmod: Can't open /lib/modules/2.4.22-1.2115.nptl/modules.dep for writing

[Dolda2000]

That's interesting... Run the following command:

strace -o depmod.strace depmod -a

That will produce a file called depmod.strace. It would a really good thing if you could post it here.

By the way, you ran depmod as root, right?

[wriggles]

Yes I ran depmod as root.
ran the strace and here is the output to the depmod.stace file

[Dolda2000]

It seems your entire module directory is lost. Do you have /lib/modules/2.4.22-1.2115.nptl?

[wriggles]

Yes its there

[Dolda2000]

In that case, the only explanation that I can find for that error message is indeed that depmod wouldn't be run as root. One thing that is sure is that this is really strange... Can you post the output of the following commands (running as root)?

ls -la /lib/modules/2.4.22-1.2115nptl
uname -a
id
ls -l /sbin/depmod
cat /proc/mounts
