Hello, On EFI systems I'd like to RAID mirror /boot partition. For HW RAID there's no issue since access to the disk or any partitions should be totally transparent to the bios. For Fake RAID, I'm not sure but I would say that the bios is able to read the RAID metadata as well. For (md) Soft RAID, I don't know. I would say that the bios is unlikely to understand the md metadata stored in the /boot partition so it won't work. Is that correct ? If so does that mean I can't mirror /boot partition on EFI systems ? Maybe creating a RAID device using the whole disk (not the partition device) would work ? Thanks for your enlightments. -- Francis -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
