ZFS is like learning to drive an 18-wheel truck after you have
lots of experience in cargo vans: you're certain that it can do
all sorts of things very reliably, and if you mess it up, you
will feel that it's entirely your own fault for not reading
and/or getting good advice first.
E.g.: when you set up an ext4fs on a laptop, you trust that mkfs
has, if not optimal defaults, certainly reasonable defaults.
"zfs create" has reasonable defaults, but the prerequisite
"zpool create" does not. Read carefully, and figure out what
ashift setting you want before you run anything.
