I just installed RH9 in a RAID1 root partition and have to use lilo instead of grub :-(

Using the raidhotadd utility to re-add the missing ('kicked') partitions and then force a resync seems to have fixed this. The remaining problem is getting the system to boot correctly using Grub. Grub does not have support for mirrored (RAIDed) disks.
Thanks

If you have a spare disk, copy all data to that disk and reinstall. Then restore the data.
Don't know if you can modify the disks order of a RAID1.
As far as I know, the /etc/raidtab is not readed until you run mkraid. So, maybe if just a problem with drive letters, ie, hda, hdb, etc.

In order to convert my machine from a 100% Linux box running software
RAID (RAID-1 on a total of two physical disks) to dual-boot Windows 2000
and Linux, with an added CD-RW drive, I had to:
1. Move connector IDE0 (primary master drive) to connector IDE4 on my
Gigabyte GA-8IHXP2 board (has 2 extra IDE connectors that were converted
from Promise RAID to ATA functionality)
2. Add a new drive to connector IDE0
3. Leave the Asus DVD-ROM drive on connector IDE1 alone, set up as master
4. Add the CD-RW to the secondary (slave) connector on IDE1
5. Leave the second Linux disk, which is device /dev/hde1, alone on connector IDE3.
So the drive device list is:
/dev/hda (Grub's hd0) -- boot drive, has Grub installed on master boot record
/dev/hde (Grub's hd1) -- mirror drive
/dev/hdg (Grub's hd2) -- what used to be the Linux boot drive, /dev/hda
I then went into Rescue mode and made a mistake: I didn't check carefully to see what disk rescue mode was mounting. I assumed (stupidly, I guess) that it was mounting /dev/hdg. I was wrong, it mounted /dev/hde.
Then I went right ahead and edited /etc/raidtab and /etc/fstab to reflect the new devices. I think I created a mess from all this; I made hde "dirty" but don't know exactly what it means. Here is the relevent portions of dmesg:

How do I fix this problem?
