In an attempt to increase I/O performance I'm trying to deploy a kind of pool I've never deployed before.
I have twelve disks to work with, and the configuration I'd like to have at the end is a three way mirror composed of 4-disk stripes...
Say that I have disks labled d1-d12...
what I'd like is to have the following as a single striped devices (raid0): d1-d4, d5-d8, d9-d12
then create a three way mirror across those devices.
But I'm not sure how to get zpool create to do that... or if it is even possible.
