it looks like you wound up with an efi bootloader splatted over the
front of your partition. maybe the raid got scrambled around? Or maybe
someone actually installed a bootloader over an otherwise-ok filesystem?
hard to say. not sure what could have prevented either of those.
are you sure the raid is in the right shape, and in the right order of
disks?
i also remember something about parted (maybe...) finding a backup gpt
signature at the end of a disk, and "helpfully" copying it over the
front end if so. This was a bug. sgi guys do you remember?
