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?
