ZFS cannot remove vdevs (yet; this is planned as one of a series of changes collectively known as BP rewrite), so you cannot go from having two raidz vdevs down to one. Your best bet is to replace the smaller disks one at a time, or copy your data somewhere else and then back onto a new pool. Or wait for the BP rewrite changes to make it out.

Disks are cheap these days, and they give you a place to put backups. As expensive as more disks sound, they're the simplest solution to this problem. Either buy one more disk and replace the raidz vdev with a larger one, or buy three more, build your ideal pool, and copy things over. Then use the remaining disks to make a backup of the things that are important to you. > With all of those drives at 1TB, that would effectively give 4TB of storage > with one drive used for parity (or so I assume). That configuration would have that capacity, yes.
