4. What is this gnop stuff for?
Can't comment on the rest, but gnop is required to create 4K-aligned vdevs
where the minimum block size is 4K (aka ashift=12).
Right, but to emphasize: the gnop hack forces ZFS to 4K blocks. It does
not, by itself, guarantee alignment with 4K native blocks on the drive,
that has to be done by making the partitions aligned.
