Controlling Share Semantics

By default, all file systems are unshared. To share a new file system, use zfs set syntax similar to the following:

# zfs set sharenfs=on tank/home/eschrock

The property is inherited, and file systems are automatically shared on creation if their inherited property is not off. For example:

# zfs set sharenfs=on tank/home
# zfs create tank/home/bricker
# zfs create tank/home/tabriz
# zfs set sharenfs=ro tank/home/tabriz

Both tank/home/bricker and tank/home/tabriz are initially shared writable because they inherit the sharenfs property from tank/home. Once the property is set to ro (readonly), tank/home/tabriz is shared read-only regardless of the sharenfs property that is set for tank/home.
