[zfs-discuss] n00b Question on drive partitioning for zfs

Like you said, I think you want ashift=12.

If you're not going to use the extra space for something else, just give
all three whole disks to ZFS. Then later, you can replace the 1 TB disk
with a 2 TB disk and immediately double the usable space.

Or, since you're only going to get 2 TB of usable space out of this for
now, why not just mirror the 2 TB drives and forget about the 1 TB disk?
