So use tur then. First problem solved.

Fdisk? Don't partition it: use logical volumes instead:
pvcreate/vgcreate/lvcreate.
- You'd need parted (gpt) rather than fdisk to partition large devices
and then kpartx.
Now run 'blockdev --getss' to check whether or not the sector size gets
propagated correctly from the underlying device to the multipath device.
