Dear All,

I'm trying to install Centos 4.2 x86_64 on a new Opteron server, using a software raid 1 boot partition.

Here is the appropriate section of my kickstart.cfg

#System bootloader configuration bootloader --location=mbr #Clear the Master Boot Record zerombr yes #Partition clearing information clearpart --all --initlabel #Disk partitioning information part raid.01 --size 50000 --asprimary --ondisk sda part raid.02 --size 50000 --asprimary --ondisk sdb raid / --level=1 --device=md0 --fstype ext3 raid.01 raid.02 ######################################

Unfortunately, when the server completes the install and reboots I am stuck at a GRUB prompt.

Typing the following at the grub prompt allows me to boot:

root (hd1,0) kernel /boot/vmlinuz-2.6.9-22.ELsmp ro root=/dev/md0 initrd /boot/initrd-2.6.9-22.ELsmp.img boot

But, once booted grub-install fails:

grub-install --root-directory=/boot /dev/sda /dev/md0 does not have any corresponding BIOS drive

If I don't use software raid for the root partition, all works fine, but this erodes the redundancy of my server...

Have I suddenly started doing something wrong, or is there a new bug out there that needs whacking ?

I'd be grateful for your comments!

Jake
