RAID1 Software on a running system

[Melka]

Hi everyone,
I ve follow this tutorial --> http://howtoforge.net/software-raid1-grub-boot-debian-etch

but just until the end, i meet a problem with grub.
I can boot on hd0 but not on hd1. There is the error message :

root (hd1,0)
Error 15 file not found

In page 3 there is a comment who said remenber grub part3, but i don know if im doing well...

Anyone got and idea ?

What's in /boot/grub/menu.lst?
Did you install GRUB on both hard drives (using the grub command, as shown in the tutorial)?

hi,
I've finally reinstall my system and make the RAID1 during the install.
Thanks anyway !
