You don't mention setting "autoexpand=on" - I suppose it would not
work without that.

What we have here is most likely not a problem with the raid or it's
growth, but a kind of "autority conflict" between ZFS and GPT on who
is going to manage the underlying partitions. (Which doesn't surprize
me - if I were ZFS, I would be quite frustrated to run under GPT.)
