I did not even know that fstype in the disklabel can be "ZFS". I have only seen "swap" and "4.2BSD" so far. $ gpart add -t freebsd-zfs md0s1 && disklabel md0s1 md0s1a added # /dev/md0s1: 8 partitions: # size offset fstype [fsize bsize bps/cpg] a: 4095 0 ZFS c: 4095 0 unused 0 0 # "raw" part, don't edit $ [dd] > > !!!
