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.
