They don't. But that might be due to misalignment of the RAID and/or LVM. At least mdadm complains when re-adding the drives after repartitioning: jigsaw kernel: [309626.806978] md0: Warning: Device sdd1 is misaligned I am not sure what exactly is misaligned here. I don't think it's the partition anymore, since parted like the new layout. At least it doesn't complain.
