This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.

This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am using Mandrake 10, with 2 harddisk, i am doing raid between 2 harddisk. So both harddisk are exactly the same. Primary harddisk in on IDE1, and secondary is on IDE2. In normal condition the PC able to boot up from Primary harddisk. But if the primary fail than if i restart than the pc will not able to restart, i think it is something to do with the boot loader from the secondary harddisk. I been using LILO as my boot loader.
I try to over come this problem by setting a boot floppy by using GRUB loader, because I been fail to make LILO floppy.
Mount point primary device secondary device raid device

/boot /dev/hda1 /dev/hda1 /dev/md0
my script in menu.lst for grub is:
# Sample boot menu configuration file
# Boot automatically after 30 secs.
# By default, boot the first entry.
# Fallback to the second entry.

Faild to check file system. Do you want to repair the errors?(Y/N)
(beware, you can lose data)
May i know what is my problem?Or how can I fix it?
May be can i make a boot loader into the secondary harddisk. May I have the solution?
Actually my primary is still ok now. For future consideration , if the primary harddisk down, i not able to access to the secondary harddisk. i already trying it now, i disable the primary, than i not able to access the PC at all after i restart! so now i have to do preparation. I can not take the risk for long down time for the PC, because it is company file server!
