Just did this: ========== grub> device (hd0) /dev/mapper/hpt37x_ehgjaggaf grub> root (hd0,5)/boot Filesystem type is reiserfs, partition type 0x83 grub> setup (hd0) ========== and it destroyed my RAID0. GRUB is such a piece of crap :-). It must be severely broken; since if it just sticked to writing to the device I pointed it at (hpt37x_ehgjaggaf) which is a RAID0 "virtual disk" / whatever, it should never be able to overwrite metadata out on the physical disk. Anyway, just wanted to tell you to beware. Gerte has a GRUB example on his page where he does setup (hd0,5) instead of setup (hd0), perhaps that's how it's meant to work. Gah.....
