Okay, then if the person can stand to lose even more space, do zfs
mirroring on each JBOD. Then we'd have a mirror of mirrors instead of a
mirror of raidz's.
Remember, the OP wanted chassis-level redundancy as well as redundancy
within the domain of each chassis. You can't do that now with ZFS unless
you combine ZFS with SVM.
I don't think we know what the OP wanted. :-)
