Harddisk:
RAID + LVM:
https://help.ubuntu.com/community/Installation/LVMOnRaid
1. /boot must not be in LVM, otherwise, the installer will force you to use LILO.  But LILO has certain advantage, as LILO install in RAID (/dev/md0), not need to install LILO on second harddisk as GRUB need to do.

For GRUB, you need to install GRUB on second harddisk manually, or your system won't boot when 1st harddisk removed.

TODO: Testing
Now, if your disks are /dev/sda and /dev/sdb, do the following to install GRUB on /dev/sda MBR:
device (hd0) /dev/sda
root (hd0,0)
setup (hd0)

This will install grub into the /dev/sdb MBR:
device (hd0) /dev/sdb
root (hd0,0)
setup (hd0)

RAID Recovery:
Clone the partition table: sfdisk -d /dev/sdX | sfdisk /dev/sdY -
