You could move the data elsewhere using zfs send and recv, destroy the original datasets and then recreate them. This would stripe the data across the vdevs. Of course, when BP-rewrite becomes available it should be possible to simply redistribute blocks amongst the various vdevs without having to go through destroying/creating.
