I have two SCSI disks on raid1.
Since I have lots of reads from that raid, I want to add two more
disks to this raid so that read will be faster.

How should I add the new disks?

Is this possible with md currently:

Create a RAID-10 on the two new disks specifying one disk missing
from each mirror.

Then copy data over and add the two existing disks letting it
resync?

Why not growing the array with 2 more disks?
