Can't add vdev

[Stanri010]

I've got a 6 drive raidz2 vdev. I just added an additional 4 drives to the system. I plan on completely rebuilding my pool once 10.0 drops but until then I want to verify my drives are good by extending my zpool with a 4 drive raidz2.

However, Freenas wont let me extend the zpool. It's complaining "You are trying to add a virtual device consisting of 4 devices in a pool that has a virtual device consisting of 6 devices."

No matter what I do, it wont let me past this screen. Am I doing something wrong?

Oh manual setup forced it through. :D

You could've run 4 way smart tests and bad blocks with out adding the drives to the pool.
