First of all, you're testing on decade old SCSI hardware that probably hasn't seen any serious use on a newer FreeBSD install in a very, very long time. Secondly, I'm confused about the concept of a "3 drive RAIDZ2". How is that even possible? Two drives have to be parity, so the last drive is... the entire dataset? Why aren't you just doing a 3-way mirror? And finally yes, you can just yank drives in a ZFS array to simulate a failure. After reinsertion you have to manually add them back to the pool, but it certainly works.
