Thanks, your email is incredibly helpful. As far as the raidz2 vdevs are concerned, I keep reading on the Internet that for raidz2 you should have an even number of disks. Is this valid advice? If so, what’s the logic behind this (or if it’s not valid, why do people keep making this recommendation)?
