If you've not already seen it, RAIDZ expansion is happening. The OpenZFS project tweeted this earlier today.
So what does this mean and why you should be excited? Well, lets say you have a RAIDZ pool and you want to add more drives, well this will let you do this. For example, take an existing 5 drive RAIDZ2 and add 3 more drives to the existing pool into the existing vdev, giving you a 8 drive RAIDZ2 pool. No more adding vdevs.
At this time, it's not available in FreeNAS yet. I will repeat, IT'S NOT AVAILABLE IN FREENAS! So don't go adding drives just yet. Please continue to create vdevs as normal until this heads downstream.
This is very exciting.
