.Sh DESCRIPTION
The
.Nm
command configures ZFS datasets within a ZFS storage pool, as described in
.Xr zpool 8 .
A dataset is identified by a unique path within the ZFS namespace.
For example:
.Dl pool/{filesystem,volume,snapshot}
.Pp
where the maximum length of a dataset name is
.Sy MAXNAMELEN Pq 256B
OpenZFS 9330 - stack overflow when creating a deeply nested dataset Datasets that are deeply nested (~100 levels) are impractical. We just put a limit of 50 levels to newly created datasets. Existing datasets should work without a problem. The problem can be seen by attempting to create a dataset using the -p option with many levels: panic[cpu0]/thread=ffffff01cd282c20: BAD TRAP: type=8 (#df Double fault) rp=ffffffff fffffffffbc3aa60 unix:die+100 () fffffffffbc3ab70 unix:trap+157d () ffffff00083d7020 unix:_patch_xrstorq_rbx+196 () ffffff00083d7050 zfs:dbuf_rele+2e () ... ffffff00083d7080 zfs:dsl_dir_close+32 () ffffff00083d70b0 zfs:dsl_dir_evict+30 () ffffff00083d70d0 zfs:dbuf_evict_user+4a () ffffff00083d7100 zfs:dbuf_rele_and_unlock+87 () ffffff00083d7130 zfs:dbuf_rele+2e () ...

Enough time has passed that 16K can be reasonably assumed to be the default value. It was increased in the 3.15 kernel released in June of 2014.

.Pp
A dataset can be one of the following:
.Bl -tag -offset Ds -width "file system"
.It Sy file system
Can be mounted within the standard system namespace and behaves like other file
systems.
While ZFS file systems are designed to be POSIX-compliant, known issues exist
that prevent compliance in some cases.
Applications that depend on standards conformance might fail due to non-standard
behavior when checking file system free space.
.It Sy volume
A logical volume exported as a raw or block device.
This type of dataset should only be used when a block device is required.
File systems are typically used in most environments.
.It Sy snapshot
A read-only version of a file system or volume at a given point in time.
It is specified as
.Ar filesystem Ns @ Ns Ar name
or
.Ar volume Ns @ Ns Ar name .
.It Sy bookmark
Much like a
.Sy snapshot ,

.Ss Properties
Properties are divided into two types: native properties and user-defined
.Pq or Qq user
properties.
Native properties either export internal statistics or control ZFS behavior.
In addition, native properties are either editable or read-only.
User properties have no effect on ZFS behavior, but you can use them to annotate
datasets in a way that is meaningful in your environment.

.It Xr zfs-project 8
List, set, or clear project ID and/or inherit flag on the file(s) or directories.
Project Quota on ZFS Project quota is a new ZFS system space/object usage accounting and enforcement mechanism. Similar as user/group quota, project quota is another dimension of system quota. It bases on the new object attribute - project ID. Project ID is a numerical value to indicate to which project an object belongs. An object only can belong to one project though you (the object owner or privileged user) can change the object project ID via 'chattr -p' or 'zfs project [-s] -p' explicitly. The object also can inherit the project ID from its parent when created if the parent has the project inherit flag (that can be set via 'chattr +P' or 'zfs project -s [-p]'). By accounting the spaces/objects belong to the same project, we can know how many spaces/objects used by the project. And if we set the upper limit then we can control the spaces/objects that are consumed by such project. It is useful when multiple groups and users cooperate for the same project, or a user/group needs to participate in multiple projects. Support the following commands and functionalities: zfs set projectquota@project zfs set projectobjquota@project zfs get projectquota@project zfs get projectobjquota@project zfs get projectused@project zfs get projectobjused@project zfs projectspace zfs allow projectquota zfs allow projectobjquota zfs allow projectused zfs allow projectobjused zfs unallow projectquota zfs unallow projectobjquota zfs unallow projectused zfs unallow projectobjused chattr +/-P chattr -p project_id lsattr -p This patch also supports tree quota based on the project quota via "zfs project" commands set as following: zfs project [-d|-r] <file|directory ...> zfs project -C [-k] [-r] <file|directory ...> zfs project -c [-0] [-d|-r] [-p id] <file|directory ...> zfs project [-p id] [-r] [-s] <file|directory ...> For "df [-i] $DIR" command, if we set INHERIT (project ID) flag on the $DIR, then the proejct [obj]quota and [obj]used values for the $DIR's project ID will be shown as the total/free (avail) resource.

Native Encryption for ZFS on Linux This change incorporates three major pieces: The first change is a keystore that manages wrapping and encryption keys for encrypted datasets. These commands mostly involve manipulating the new DSL Crypto Key ZAP Objects that live in the MOS. Each encrypted dataset has its own DSL Crypto Key that is protected with a user's key. This level of indirection allows users to change their keys without re-encrypting their entire datasets. The change implements the new subcommands "zfs load-key", "zfs unload-key" and "zfs change-key" which allow the user to manage their encryption keys and settings. In addition, several new flags and properties have been added to allow dataset creation and to make mounting and unmounting more convenient. The second piece of this patch provides the ability to encrypt, decyrpt, and authenticate protected datasets. Each object set maintains a Merkel tree of Message Authentication Codes that protect the lower layers, similarly to how checksums are maintained. This part impacts the zio layer, which handles the actual encryption and generation of MACs, as well as the ARC and DMU, which need to be able to handle encrypted buffers and protected data. The last addition is the ability to do raw, encrypted sends and receives. The idea here is to send raw encrypted and compressed data and receive it exactly as is on a backup system. This means that the dataset on the receiving system is protected using the same user key that is in use on the sending side. By doing so, datasets can be efficiently backed up to an untrusted system without fear of data being compromised.

I did this when topics were either too short to warrant their own file or so interrelated that a user would want to refer between commands in the same file. Corrected .Sx internal references to .Xr cross refs; lots of .Sx references from when text was all in zfs.8 needed to be changed to .Xr zfs-$SUBCOMMAND 8 cross references. Divided subcommand list in zfs(8) into sections of related functionality. This required writing new descriptions for some commands. Preserved ".Os Linux", `.Os` macro parsing behavior differs between mandoc from the "BSD" mandoc package (available on Ubuntu) and man from Ubuntu's man-db package, which calls groff to format the manpages. Groff handles the `.Os` macro differently and wrongly, defaulting it to "BSD" in `/usr/share/groff/*/tmac/mdoc/doc-common`, instead of getting the default from `uname`. A future set of changes will introduce build-time preprocessing of manpages for platform-specific documentation and can insert the correct operating system name. Added SEE ALSO sections, the newly-divided zfs-*.8 subcommand man pages needed their own SEE ALSO sections pointing to related subcommands and, in some cases, documentation from other packages (e.g. zfs-share.8).

Samba must be able to authenticate a user.
This can be done in a number of ways
.Pq Xr passwd 5 , LDAP , Xr smbpasswd 5 , &c.\& .
How to do this is outside the scope of this document refer to
.Xr smb.conf 5
for more information.

See the
.Sx USERSHARES
section for all configuration options,
in case you need to modify any options of the share afterwards.
Reorganize zfs(8) man page into sections Most subcommands got their own manpages (e.g. create). Some related commands grouped into a single manpage and symlinks created (e.g. set, get, and inherit).
