This should be on the SDC list however...
There was some work underway to make this task easier, but I don't know
what became of it.
If I want a stripe of mirrors, I pull all bar one drive before the
install and then build the pool around it later.
The last couple of CNs I built had too much memory to allow this with
the smallish drives they had so I just let the install go through. I
then snapshotted the pool (modulo dump and swap), sent the snapshot to
another box, rebuilt the CN zones pool and sent the snapshot back.
Inelegant but effective!
I don't think I have ever wanted the default layout and do wish it could
be specified.
Ian.
