autoexpand is by default off. I guess this is in case someone do something as replacing two 500GB drives with two 1TB drives and then wants to replace those with new 500GB drives, since setting autoexpand=on is quite simple and for the expansion, irreversible. If you have expanded a VDEV, the only way to shrink it is to backup, reconfigure ZFS and restore.
