Hi, the trick is, you can't boot on the MBR installed on a _software_ raid1 partition _but_ you _can_ if you're going to install the MBR on all the member disks of that software raid1 partition.
assuming that you're trying to boot from "/boot" residing in a raid1 partition "/md3" which includes "/dev/sda3" and "/dev/sdb3", go to a grub shell and then try a similar set of commands: grub> device (hd0) /dev/sda3 grub> root (hd0,0) grub> setup (hd0) grub> device (hd0) /dev/sdb3 ; to make the MBR look correct whenever the 1st disk fails grub> root (hd0,0) grub> setup (hd0) then grub.conf should look similar to this: .... root (hd0,0) kernel /vmlinuz.... root=/dev/md1 .... * you might want to use hd1 for /dev/sdb3 but you'll be needing a separate entry for it on grub.conf in case of a failure on the 1st disk. and then boot. hopefully, you'll find this template useful. just goog for "boot software raid" for more info.

Hi, I am trying to set up an 64-bit AMD server, with two (2) 120GB and two (2) 320GB SATA hard drives. I tried to install ubuntu-7.04-server-amd64.isoon the machine and made two (2) raid1 configurations on the two sets of hard drives. I configured it via manually editing the partition tables. There wasn't any problem during the installation, I was able to create three partitions, md0 swap, md1 / and md2 /var. However, whenever the installation is done and the machine reboots, I get the message, "GRUB Loading stage1.5 Error 17." Can someone guide me on how to effectively configure raid1 on feisty fawn server installation? Thanks.
