Careful with that. My fdisk (from util-linux-ng 2.17.2)
does 1MB alignment for the first partition, but then it does
no alignment at all for the 3 primary partitions and
while it puts 1MB between the logical partitions, that
also does not result in alignment to anything as far as
I can tell.
I suspect that you have to align yourself for the
partitions. This was with a new, blank disk, but I
gave sizes in kB, as the partitions go into RAID sets.
Maybe it aligns if you give sizes in MB.
