Having been bit by this, I certainly agree with having this feature
default to "off".  It's surprising when detaching a disk causes the
rubber band to snap outwards.

However, what explicit command can I use when I want to cause the
expansion to occur?  With SVM, I would have done my disk manipulations
(whatever they were) and then finally told SVM to sync up with the
largest available disk in the pool like this:

	# metattach d1

Shouldn't there be a command like "zpool grow <pool>"?
