In this example, a file system that acts as a container for individual file systems is created.
# zfs create tank/home
After the file system hierarchy is established, set up any properties to be shared among all users:
# zfs set mountpoint=/export/zfs tank/home # zfs set share.nfs=on tank/home # zfs set compression=on tank/home # zfs get compression tank/home NAME PROPERTY VALUE SOURCE tank/home compression on local
You can set file system properties when the file system is created. For example:
# zfs create -o mountpoint=/export/zfs -o share.nfs=on -o compression=on tank/home
For more information about properties and property inheritance, see Introducing ZFS Properties.
Next, individual file systems are grouped under the home file system in the pool tank.
File systems could have been created and then the properties could have been changed at the home level. All properties can be changed dynamically while file systems are in use.
# zfs create tank/home/jeff # zfs create tank/home/bill
These file systems inherit their property values from their parent, so they are automatically mounted at /export/zfs/user and are NFS shared. You do not need to edit the /etc/vfstab or /etc/dfs/dfstab file.

In this example, user jeff is assigned a quota of 10 GBs. This property places a limit on the amount of space he can consume, regardless of how much space is available in the pool.
# zfs set quota=10G tank/home/jeff
View available file system information by using the zfs list command:
# zfs list NAME USED AVAIL REFER MOUNTPOINT tank 92.0K 67.0G 9.5K /tank tank/home 24.0K 67.0G 8K /export/zfs tank/home/bill 8K 67.0G 8K /export/zfs/bill tank/home/jeff 8K 10.0G 8K /export/zfs/jeff
Note that user jeff only has 10 GB of space available, while user bill can use the full pool (67 GB).
