Just curious. I setup a zfs raidz2 with 6 disks that are 6tb each. So I have 36 tb raw and 24tb usable. The server has 12 bays in it but we initally started with 6 drives. No where near close to full yet. But I was curious is if I needed to expand the capacity of the array, can I added more 6tb drives or do I simply replace the 6tb with larger drives 1 at a time and let the rebuild occur? What's the best way to do this?
