So to do nfs with ZFS, all you need to do is: 1. add zfs_enable="YES" to /etc/rc.conf 2. restart mountd (i.e. /etc/rc.d/mountd restart) 3. add your zfs shares: zfs sharenfs=on myzpool/test1 zfs sharenfs="-maproot=root -alldir -network 10.0.0.3 -mask 255.255.255.255" myzpool/test2 NOTE: sharenfs=on creates a nfs share that is available to everyone. You should now be able to mount the zfs nfs filesystems on other systems or locally. mount -t nfs myserver:/myzpool/test1 /mnt Unlike /etc/exports, zfs nfs shares are available immediately, no need to restart mountd.
