I can't tell what you are missing since you haven't said anything about
what you've done.

newfs will work fine, however you need to use something other than
MS-DOS MBR partition tables or bsdlabels if you wish to partition the
disk.  GPT should work.  According the the status page, snapshots are
broken so background fsck apparently isn't an option.  The somewhat
outdated status page is here:
