This reminds me: what paranoid safety measures can one take? E.g keep an external log of the filesystem as well?
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?
Thanks for the thoughts! Gaspar
