Question:
How does the ZFS option 'copies=n' and raid relate to and interact with
each other? specifically recovery in the event of a failure. For
example, is having three disks in a raid-1 configuration with copies=1
effectively the same as having three disks in a raid-0 with copies=3?
Are the copies distributed uniformly across all drives in the pool, or
concentrated, or what? What happens with configs like a raid-z2 with
copies=2? Which / how many disks can you lose?
(I'm aware that like a lot of other ZFS options copies=n doesn't have to
be global to the entire pool / directory structure, but for the sake of
simplicity let's assume it is in this case).
