See

values.
|

Numeric values can be specified as exact values, or in a human-readable form
|
|
with a suffix of
|

|
|
Displays properties for the given datasets.
|
|
If no datasets are specified, then the command displays properties for all
|
|
datasets on the system.
|
|
For each property, the following columns are displayed:
|
|
.Bl -tag -compact -offset 4n -width "property"
|
|
.It Sy name
|
|
Dataset name
|
|
.It Sy property
|
|
Property name
|
|
.It Sy value
|
|
Property value
|
|
.It Sy source
|
|
Property source
|
|
.Sy local , default , inherited , temporary , received , No or Sy - Pq none .
|
|
.El
|
|
.Pp
|
|
All columns are displayed by default, though this can be controlled by using the
|
|
.Fl o
|
|
option.
|
|
This command takes a comma-separated list of properties as described in the
|
|
.Sx Native Properties
|
|
and
|
|
.Sx User Properties
|
|
sections of
|
|
.Xr zfsprops 7 .
|
|
.Pp
|
|
The value
|
|
.Sy all
|
|
can be used to display all properties that apply to the given dataset's type
|
|
.Pq Sy filesystem , volume , snapshot , No or Sy bookmark .
|
|
.Bl -tag -width "-s source"
|
|
.It Fl H
|
|
Display output in a form more easily parsed by scripts.
|
|
Any headers are omitted, and fields are explicitly separated by a single tab
|
|
instead of an arbitrary amount of space.
|
|
.It Fl d Ar depth
|
|
Recursively display any children of the dataset, limiting the recursion to
|
|
.Ar depth .
|
|
A depth of
|
|
.Sy 1
|
|
will display only the dataset and its direct children.
|
|
.It Fl o Ar field
|
|
A comma-separated list of columns to display, defaults to
|
|
.Sy name , Ns Sy property , Ns Sy value , Ns Sy source .
|
|
.It Fl p
|
|
Display numbers in parsable
|
|
.Pq exact
|
|
values.
|
|
.It Fl r
|
|
Recursively display properties for any children.
|
|
.It Fl s Ar source
|
|
A comma-separated list of sources to display.
|
|
Those properties coming from a source other than those in this list are ignored.
|
|
Each source must be one of the following:
|
|
.Sy local , default , inherited , temporary , received , No or Sy none .
|
|
The default value is all sources.
|
|
.It Fl t Ar type
|
|
A comma-separated list of types to display, where
|
|
.Ar type
|
|
is one of
|
|
.Sy filesystem , snapshot , volume , bookmark , No or Sy all .

|
|
Clears the specified property, causing it to be inherited from an ancestor,
|
|
restored to default if no ancestor has the property set, or with the
|
|
.Fl S
|
|
option reverted to the received value if one exists.
|
|
See
|
|
.Xr zfsprops 7
|
|
for a listing of default values, and details on which properties can be
|
|
inherited.
|
|
.Bl -tag -width "-r"
|
|
.It Fl r
|
|
Recursively inherit the given property for all children.
|
|
.It Fl S
|
|
Revert the property to the received value if one exists; otherwise operate as
|
|
if the
|
|
.Fl S
|
|
option was not specified.

.Sh EXAMPLES
|
|
.\" These are, respectively, examples 1, 4, 6, 7, 11, 14, 16 from zfs.8
|
|
.\" Make sure to update them bidirectionally
|
|
.Ss Example 1 : No Creating a ZFS File System Hierarchy
|
|
The following commands create a file system named
|
|
.Ar pool/home
|
|
and a file system named
|
|
.Ar pool/home/bob .
|
|
The mount point
|
|
.Pa /export/home
|
|
is set for the parent file system, and is automatically inherited by the child
|
|
file system.
|
|
.Dl # Nm zfs Cm create Ar pool/home
|
|
.Dl # Nm zfs Cm set Sy mountpoint Ns = Ns Ar /export/home pool/home
|
|
.Dl # Nm zfs Cm create Ar pool/home/bob
|
|
.
|
|
.Ss Example 2 : No Disabling and Enabling File System Compression
|
|
The following command disables the
|
|
.Sy compression
|
|
property for all file systems under
|
|
.Ar pool/home .
|
|
The next command explicitly enables
|
|
.Sy compression
|
|
for
|
|
.Ar pool/home/anne .
|
|
.Dl # Nm zfs Cm set Sy compression Ns = Ns Sy off Ar pool/home
|
|
.Dl # Nm zfs Cm set Sy compression Ns = Ns Sy on Ar pool/home/anne
|
|
.
|
|
.Ss Example 3 : No Setting a Quota on a ZFS File System
|
|
The following command sets a quota of 50 Gbytes for
|
|
.Ar pool/home/bob :
|
|
.Dl # Nm zfs Cm set Sy quota Ns = Ns Ar 50G pool/home/bob
|
|
.
|
|
.Ss Example 4 : No Listing ZFS Properties
|
|
The following command lists all properties for
|
|
.Ar pool/home/bob :
|
|
.Bd -literal -compact -offset Ds
|
|
.No # Nm zfs Cm get Sy all Ar pool/home/bob

|
.No # Nm zfs Cm get Fl H o Sy value compression Ar pool/home/bob
|
|
on
|

|
|
.Ss Example 5 : No Inheriting ZFS Properties
|
|
The following command causes
|
|
.Ar pool/home/bob No and Ar pool/home/anne
|
|
to inherit the
|
|
.Sy checksum
|
|
property from their parent.
|
|
.Dl # Nm zfs Cm inherit Sy checksum Ar pool/home/bob pool/home/anne
|
|
.
|
|
.Ss Example 6 : No Setting User Properties
|
|
The following example sets the user-defined
|
|
.Ar com.example : Ns Ar department
|
|
property for a dataset:
|
|
.Dl # Nm zfs Cm set Ar com.example : Ns Ar department Ns = Ns Ar 12345 tank/accounting
|
|
.
|
|
.Ss Example 7 : No Setting sharenfs Property Options on a ZFS File System
|
|
The following commands show how to set
|
|
.Sy sharenfs
|
|
property options to enable read-write
|
|
access for a set of IP addresses and to enable root access for system
|
|
.Qq neo
|
|
on the
|
|
.Ar tank/home
|
|
file system:
|
|
.Dl # Nm zfs Cm set Sy sharenfs Ns = Ns ' Ns Ar rw Ns =@123.123.0.0/16:[::1],root= Ns Ar neo Ns ' tank/home
|
|

If you are using DNS for host name resolution,
|
|
specify the fully-qualified hostname.
