SuSE system that was working now fails to boot


Greetings. I'm not even a newbie yet.
I have a dell 2650 server, raid 5 in good condition. We installed SuSE 9.3 in 2006 and use this machine as an SFTP server. it has been rock solid until a recent power cycle.
Am getting Grub error 17 when it starts so i booted from the CD. Used YAST to look at the logs and when the fault occured i see "linux modules FATAL: could not load /lib/modules/2.6.11.4-20A-default-modules.dep"
I also see I/O error dev fd0 sector 0. The raid controller says the array is optimal so this error is confusing.
Any ideas? remember I know near nothing about linux yet.
Thanks in Advance!
John

I ran the automatic repair and at the end I get the following message:
grup> setup-- stage 2=/boot/grub/stage2 (hd0)(hd0,1)
ERROR 24: attempt to access block outside partition.
grub> quit

i have no idea how to fix this.

Thanks,
John

Step one...

Get yourself a copy of both of the following;
Gparted Live CD
&
PartedMagic Live CD

If you look at the following blog, you will notice that this is an error which is not unheard of (maybe a little less anxiety can be found in that);
http://jaykinzer.blogspot.com/2008/0...ess-block.html

However, that blogger's solution is probably beyond you... and you're going to need tools to do it that will make you more comfortable,... hence my download suggestions...

From the Live CDs, it should be possible to fix your grub error (SuSE 9.3 almost assured used Grub as opposed to Grub2). And, the Live CDs will likely let you do it with a graphical text editor... But having the Live CDs will help make sure that the error wasn't cause by another problem (physical problem like failing sectors, etc.).

further tests and results

Thank you for the very quick reply and advice.
Here is what I did:

I downloaded Gparted Live and used it to check the raid array. Results said there was nothing wrong.

Then loaded partedmagic 6.7 and looked at the hardware (OK).
Using file manager i inspected /boot/grub/menu.lst and it appears to be OK when I compare the file to a beta desktop pc we used originally as a test platform.

Next I opened a terminal and from root, tried the procedure in one of your links:
I typed
# grub

reply
grub>

I typed
find /boot/grub/menu.lst

reply
error 15 file not found

Not sure what's going on since the file is present.
Any further advice?
John

Found a strange nested file structure where grub is located

As I was looking at parted magic file manager, i see that there is a large number of nested boot folders
Specifically, I have the following structure:

/media/sda2/bootboot/boot/boot/boot/boot and continuing 41 times!
This seems wrong to me.
each of the boot folders has the same files in it.
Can anyone explain how this happened and is there any advice on how to clean this mess up?

Thanks,
john

Wow.

I managed /boot/boot once, and felt a real twit. Once you start into grub config files, '/' means '/boot' and repeated 'setup' or 'install' commands to grub (as from a script) might just do that. In there at the back might be a grub/ subdirectory that the system is using. First try
Code:
 cd /boot
du -sh boot
My /boot/grub/ is a bit shy of 350k - just to give you an idea of size. If you do find a subdirectory in there you could try something like this
Code:
 cd /boot
mv boot/boot/ . . . . .boot/boot/grub /boot
ln -s ./ boot
This will always show a symlink 'boot' pointing to the current directory :-D. It's probably too much of a bodge to work, and I would set grub up once more to be sure.
