To All,
I have given up on the idea of having IDE RAID the costs are just too high to have a proper hardware RAID (like Adaptec cards etc).
I have setup a mandrake system, as it supports RAID as an install option, which is nice!
My BIOS unfortunately does not let me boot off the second drive (which is bad), which means should the first drive in the array fail I would be, well, up the paddle without a creek!
What I intend to do is use a boot disk to boot the system into its RAID state, so it doesn't matter which drive is down, so my boot order will go Prim IDE, Floppy, CD.
There are two things I could do with help with!
1. Why can't I boot off the secondary IDE? It comes up with L 01 01 01 01 01 01 01 etc 01DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER. I am sure this is a BIOS problem.
2. How \ What do I need to create the boot disk simply to kick off the boot process off any drive?
My RAID config works like this:
Md0 mounted on /boot is a boot array MD1 mounted on / is the rest.
Any help would be great, TIA.
Michael
OK, I give up, its not the second drive, it's the fact that my RAID array doesn't work at all if one of the disks fail! What is going on!!! Help really needed now! I thought I was doing so well too! :o(
All the best
Michael

Erm, ow. I've seen that but not for a long time (I tend to use grub these days). I think it was caused by a missing "linear" directive when writing lilo to the drive.
Searching the web threw up http://lists.suse.com/archive/suse-linux/2002-Jun/1386.html which I think says rude things in German about /boot on RAID. In English, there's an interesting thread around http://archives.linuxfromscratch.org/mail-archives/lfs-support/2002-June/007...

A kernel with raid, IDE, ext3 (or whatever) and probably syslinux is simplest. syslinux is at http://syslinux.zytor.com/
