In the last few days, I was struggling to convert a remote machine with
two identical SATA disks (sda and sdb) to a Software RAID 1. Especially
the boot-part was tricky as I had no console access to the machine. The
whole procedure was done remotely via SSH. I use the md tools (mdadm)
and lilo

Maybe Goswin, or somebody else who enabled booting from both

Hello,
I now tested RAID1 together with grub by unplugging the
1st disk (to be sure, I tested with the 2nd as well).
As you can read further up in this thread I did
run 'grub-install --no-floppy /dev/sdb' to install
the boot-loader in the MBR of the 2nd disk /dev/sdb.
Then I halted the computer

Have you tried removing sda and boot or swap sda and sdb around and
boot?
Hi!
I use ms-sys with -s option just a week ago in simular situation.
As far as I know, you can't indicate grub to load from /dev/md0, only
lilo can do this.
And there is no need to recompile the kernel, the debian distributed
kernel with the yaird as
