Well I've tried exactly that: I've aggregated two partitions in RAID1, made the file system, then tried to install Grub on them (as in run grub-setup or grub-install or grub and then from the shell the setup)... And I didn't succeeded. I've tried the following: * try to install Grub on the MD as it would have been a partition -- failed (as expected as the MD device is not on a hard-drive); * stopped the MD, and then tried to install grub on each partition individually -- it worked to install, but from a reason I don't remember right now it failed to boot; So what intrigues me is how you've initialized the MBR, how you've runned grub-setup? (In the end I am more pleased with two boot partitions, as if I miss-configure one, I'll have the other one to boot from. I've also cross-referenced the grub menu to chain-load the other disk.) Thanks, Ciprian.
