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 and the maximum amount of nesting allowed in a path is 50 levels deep. .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 , but without the hold on on-disk data. It can be used as the source of a send (but not for a receive). It is specified as .Ar filesystem Ns # Ns Ar name or .Ar volume Ns # Ns Ar name . .El .Pp See .Xr zfsconcepts 7 for details. . .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. For more information about properties, see .Xr zfsprops 7 . . .Ss Encryption Enabling the .Sy encryption feature allows for the creation of encrypted filesystems and volumes. ZFS will encrypt file and zvol data, file attributes, ACLs, permission bits, directory listings, FUID mappings, and .Sy userused Ns / Ns Sy groupused Ns / Ns Sy projectused data. For an overview of encryption, see .Xr zfs-load-key 8 . . .Sh SUBCOMMANDS All subcommands that modify state are logged persistently to the pool in their original form. .Bl -tag -width "" .It Nm Fl ?

If a hold exists on a snapshot, attempts to destroy that snapshot by using the .Nm zfs Cm destroy command return .Sy EBUSY . .It Xr zfs-diff 8 Display the difference between a snapshot of a given filesystem and another snapshot of that filesystem from a later time or the current contents of the filesystem. .El . .Ss Clones .Bl -tag -width "" .It Xr zfs-clone 8 Creates a clone of the given snapshot. .It Xr zfs-promote 8 Promotes a clone file system to no longer be dependent on its .Qq origin snapshot. .El . .Ss Send & Receive .Bl -tag -width "" .It Xr zfs-send 8 Generate a send stream, which may be of a filesystem, and may be incremental from a bookmark. .It Xr zfs-receive 8 Creates a snapshot whose contents are as specified in the stream provided on standard input. If a full stream is received, then a new file system is created as well. Streams are created using the .Xr zfs-send 8 subcommand, which by default creates a full stream. .It Xr zfs-bookmark 8 Creates a new bookmark of the given snapshot or bookmark. Bookmarks mark the point in time when the snapshot was created, and can be used as the incremental source for a .Nm zfs Cm send command. .It Xr zfs-redact 8 Generate a new redaction bookmark. This feature can be used to allow clones of a filesystem to be made available on a remote system, in the case where their parent need not (or needs to not) be usable. .El . .Ss Properties .Bl -tag -width "" .It Xr zfs-get 8 Displays properties for the given datasets. .It Xr zfs-set 8 Sets the property or list of properties to the given value(s) for each dataset. .It Xr zfs-inherit 8 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. .El . .Ss Quotas .Bl -tag -width "" .It Xr zfs-userspace 8 Ns / Ns Xr zfs-groupspace 8 Ns / Ns Xr zfs-projectspace 8 Displays space consumed by, and quotas on, each user, group, or project in the specified filesystem or snapshot. .It Xr zfs-project 8 List, set, or clear project ID and/or inherit flag on the file(s) or directories. .El . .Ss Mountpoints .Bl -tag -width "" .It Xr zfs-mount 8 Displays all ZFS file systems currently mounted, or mount ZFS filesystem on a path described by its .Sy mountpoint property. .It Xr zfs-unmount 8 Unmounts currently mounted ZFS file systems. .El . .Ss Shares .Bl -tag -width "" .It Xr zfs-share 8 Shares available ZFS file systems. .It Xr zfs-unshare 8 Unshares currently shared ZFS file systems. .El . .Ss Delegated Administration .Bl -tag -width "" .It Xr zfs-allow 8 Delegate permissions on the specified filesystem or volume. .It Xr zfs-unallow 8 Remove delegated permissions on the specified filesystem or volume. .El . .Ss Encryption .Bl -tag -width "" .It Xr zfs-change-key 8 Add or change an encryption key on the specified dataset. .It Xr zfs-load-key 8 Load the key for the specified encrypted dataset, enabling access. .It Xr zfs-unload-key 8 Unload a key for the specified dataset, removing the ability to access the dataset. .El . .Ss Channel Programs .Bl -tag -width "" .It Xr zfs-program 8 Execute ZFS administrative operations programmatically via a Lua script-language channel program. .El . .Ss Jails .Bl -tag -width "" .It Xr zfs-jail 8 Attaches a filesystem to a jail. .It Xr zfs-unjail 8 Detaches a filesystem from a jail. .El . .Ss Waiting .Bl -tag -width "" .It Xr zfs-wait 8 Wait for background activity in a filesystem to complete. .El . .Sh EXIT STATUS The .Nm utility exits .Sy 0 on success, .Sy 1 if an error occurs, and .Sy 2 if invalid command line options were specified. . .Sh EXAMPLES .Bl -tag -width "" . .It Sy 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 .

This bookmark can then be used instead of snapshot in send streams. .Dl # Nm zfs Cm bookmark Ar rpool Ns @ Ns Ar snapshot rpool Ns # Ns Ar bookmark . .It Sy Example 24 : No Setting Sy sharesmb No Property Options on a ZFS File System The following example show how to share SMB filesystem through ZFS. Note that a user and their password must be given. .Dl # Nm smbmount Ar //127.0.0.1/share_tmp /mnt/tmp Fl o No user=workgroup/turbo,password=obrut,uid=1000 .Pp Minimal .Pa /etc/samba/smb.conf configuration is required, as follows. .Pp Samba will need to bind to the loopback interface for the ZFS utilities to communicate with Samba. This is the default behavior for most Linux distributions. .Pp 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. .Pp See the .Sx USERSHARES section for all configuration options, in case you need to modify any options of the share afterwards.
