thanks for all the help but I haven't found anything related to running grub with a RAID configuration. I've seen things mentioning it but comments that follow it stating that is complicated to get going and that lilo works better.
Granted, finding recent articles on this subject have not been that easy...
thanks

Now ... if it were me ... I would switch to grub if you can get your system back up.
Once the system is up, install the grub software and then install grub on both MBRs like this:
grub
Grub>device (hd0) /dev/hda Grub>root (hd0,0) and then: Grub>setup (hd0)
Grub>device (hd0) /dev/hdb Grub>root (hd0,0) and then: Grub>setup (hd0)
quit
Now that grub is on both drives just add an extra entry in menu.1st like this:
title Linux [MIRROR] kernel (hd1,1)/boot/vmlinuz root=/dev/md2 vga=0x317 splash=silent desktop resume=/dev/md3 showopts initrd (hd1,1)/boot/initrd
This is just a copy of whatever you have for linux already but changing the drive number in parenthesis.
Depending on how your motherboard's BIOS handles a failed drive, you may or may not need the second entry to boot.
I don't understand why you "haven't found anything related to running grub with a RAID configuration". The message you are responding to is exactly that. I have this running on several servers and the above is all I had to do.
In all fairness, I admit to never being very good at documentation. Perhaps someone else could explain it more clearly than I have. Also, try searching Google for "software raid grub". The first thing on the list I get is "Software Raid and Grub HOW-TO". Please ... give it a try ... it realy is pretty easy and easier to maintain than lilo. Louis
