I've just setup a bootable DMRAID(FakeRaid) RAID 0 on an old FastTrak66 using essentially the instructions on https://help.ubuntu.com/community/FakeRaidHowto
. When booting, I see a bunch of messages "Attempt to access beyond end of device". What I think is happening is that DMRAID stores the partition table of the mapped device in the partition table of the first device in the RAID. Since this is a RAID0 using the whole of two drives, that partition table represents a drive that's the sum of the sizes of the two, and is thus seen as invalid for the drive by Linux when the system comes up.
So, my question: is there a way to tell Linux to not nag me about these messages from the drive during boot? If there's a problem with the mapped array, I expect I'll see it when the raid is put together during bootup.
