Because what you posted doesn't give any information on how your
partitions are aligned, actually. Just having a FS using 4k blocksize
on top of a misaligned partition doesn't work out.
Cloning a disk using "dd", you most probably will create misaligned
partitions on any advanced format disk, which most of the newer drives
are
what exactly do you need to align on the partitions?
For a start, making sure your RAID implementation puts the metadata at
the end of the disk, rather than the beginning. If it puts it at the
beginning you need to infer how big it is, and then pre-compensate by
positioning the partition so that it begins at a 4KB boundary on the raw
disk. And then make sure all the other partitions also begin on a 4KB
raw disk boundary.
for raid-setups you usually left 10-30 MB completly unpartitioned
to make 100% sure that you get not troubles by replace a drive
That doesn't have anything to do with alignment.
