I made the above suggested change to grub.conf.
There was an update for grub for CentOS 6.2 which I installed.
I also changed /boot/grub/device.map to include both disks (sda and sdb).
# grub-install /dev/sda
No joy. I get an error:
The file /boot/grub/stage1 not read correctly.
I attempted grub installation on /dev/md_d0 as well as /dev/sdb. I
get the same above error.
I commented the line boot=/dev/... in grub.conf (in effect restore it
to the original content) and still get the same error!
Looks like Grub and md_d0 do not get along :(
Upon querying uncle Google, I came across this link which is similar
to what I am experiencing.
<http://idolinux.blogspot.in/2009/07/reinstall-grub-bootloader-on-md0.html>
I will report back when I hit upon a solution.
Meanwhile, do let me know if other ideas come to your mind.
I am also considering changing the bootloader to lilo or extlinux.
Please share any experience in configuring either for raid1.
Thanks,
