mdadm raid1 both bootable
How to modify the normal mdadm raid1 (or make during linux installation) so that both disks are bootable? All instances are sata 500GB debian amd64 lenny.

Is that convenient or is it preferable mdadm with only one disk bootable and, in case of failure, recover with knoppix?

This is what I did with my mirror after installing the OS:


# grub --no-floppy --device-map=/boot/grub/

grub> device (hd0) /dev/hda
grub> root (hd0,0)
grub> setup (hd0)

grub> device (hd0) /dev/hdc
grub> root (hd0,0)
grub> setup (hd0)

grub> quit

Addapt to your needs.

Hope this helps.
