Recently, I was in a position where I was aiding someone in
configuring five disks in RAID-Z1, and we were discussing whether or

As far as I know, this is not currently possible (as of nv b46) - is
it a planned feature to be able to dynamically add and remove disks
without destroying and recreating the RAID-Z pool?
You don't have a raid-z pool, you have a raid-z vdev in a zfs pool. It
is not possible to add devices to a raid-z vdev, but you may not want to
anyway. You may prefer to add another raid-z vdev to the zfs pool for
better performance. This does limit the granularity of disks that you can
add though, and increases the amount of "wasted" space.
Someone said being able to add devices to a raidz vdev is on the todo list.
