Bug#507399: bug installation-reports

Quoting Hilario Ortigosa Monteoliva (hilario@octanio.es):

> The system detects de 2.8 TB 'disk' (hardware raid5) and partitions it

Do you think that the problems comes from >2TB disks or >2TB *partitions*?

Otherwise said, what partitioning scheme did you choose for your 2.8TB

GRUB maintainers, could you comment here? What are the known limits?

It's very likely that it will not, given the timeframe, but we need to
document this the best way we can.
