The enclosed patch adds support for RAID1C3 and RAID1C4 to grub. I know that David already told that he want to write one; however recently I looked to the grub source and so I make a patch. I tested the patch as following: - computing the checksum of a file bigger than 64KB in a RAID1C3 filesystem (so the file is in a data bG) - computing the checksum of a file smaller than 64KB in a RAID1C3 filesystem (so the file is in the metadata BG) - computing the checksum of a file bigger than 64KB in a RAID1C4 filesystem (so the file is in a data bG) - computing the checksum of a file smaller than 64KB in a RAID1C4 filesystem (so the file is in the metadata BG) - perform the tests abowe removing some disks in order to test all the possible missing disks combination Of course the test is considered passed if the checksum matches with its correct value.
