Hi:
	I readed the information about raid10 near copy in man mdadm.
	It is:
	'n' signals 'near' copies.  Multiple copies of one data block are at similar offsets in different
              devices.
	But I think this wrong.
	If raid10 had five disks and near copy is equal three.
	The layout like:
			5 disks
--------------------
A1 A1 A1 A2 A2
A2 A3 A3 A3 A4

But the copies of datablock A2 are not at similar offset in different device.
