I've been reading all the documentation I can find - including the ZFS Storage Design Power Point - about the configuration of zdev's into zpools. I'm reusing an old IBM Intellistation workstation (nice power supply and lots of room) and I have 8 4Tb drives. None of the zdev configurations use 8 drives directly. Would it be correct to put 4 drives in zdev1, 4 drives in zdev2 and then put both of those into 1 zpool? If so, then my next question is what is the correct RAID format - raidz or raidz2?
