I finally got a 16-bay drive enclosure for the rebuild of my ZFS file server/ESXi box, and am still unsure and confused on what the drive setup should be.
Nearly all of the NAS usage comes from me in the household. Hardly anyone else uses it, other then for the SageTV PVR that stores the recorded TV shows on the pool (and even that is hardly used now-a-days). So, I've decided to not try to maximize space in the pool, but to try and maximize speed, as I really want to setup a iSCSI drive with MPIO for my main PC to house mostly my games, and allow the pool to run VMs directly off it without the horrible speeds I had before.
I currently have 10 2TB drives in my ZFS pool. I have 2 spare 2TB drives as backups not in the pool at all, so I have a total 12 2TB drives. If I go with the simplest paired Mirror setup for the best read speeds, I would have in the end 12TB of storage space, made up of 6 pairs of 2TB drives, each in a mirror, with the 6 pairs striped, in essence, a RAID10 setup. So far I understand all that.
What I am confused about is, if (when) I add in 4 more 2TB drives, to create 2 more paired mirrors, how exactly does that get added into the already created pool?
