Debian RAID-1 problem

Hi all,
I'm having trouble getting Debian 3.0 to boot off of a RAID-1 array. I or=
iginally installed onto the first SATA hard disk, but now I'm trying to c=
onvert it into a mirror array with the second disk. I created a degraded =
RAID-1 array /dev/md0 with only /dev/sdb1 as a member, mounted it, format=
ted it, and rsynced the contents of /dev/sda1 over to it. Am I doing this=
 the right way? When GRUB attempts to boot off the array, the kernel pani=
cks, claiming "ext3-fs: cannot read superblock". However, when I boot off=
 of sda1 the array md0 shows up fine with sdb1 as a member.

Debian 3.0 Woody with custom kernel-2.6.10 with raid1 compiled in, 2x 80G=
b SATA hard disks.

I've scoured ever message board, forum, and howto document I could find o=
n the subject with no luck. Help greatly appreciated.

KJA
