Description

As I learned the hard way recently grub silently truncates disk sector addresses to 32bits. This causes all sorts of pain when using large (>2TB) disks:
  • we cannot install stage2 beyond 2TB, meaning that we can't boot off EFI partitions beginning beyond 2TB
  • when rpool extends beyond 2TB on a disk we can get unexpected boot failures if the grub config file, the kernel, or the bootarchive are stored beyond the 2TB limit
