I though I would create a SWAP partition (of the same size) on both disks and 
then later on use gmirror to mirror the two SWAP partitions. 

 I've done this on some other servers before. Both disks have the same size 
SWAP and ZFS partitions. Then I use gmirror for the SWAP spaces and ZFS mirror 
for the ZFS partitions.

I think I understand the GUI better now.
