40.Nm zfs
41.Cm mount
42.Nm zfs
43.Cm mount
44.Op Fl Oflv
45.Op Fl o Ar options

51.
52.Sh DESCRIPTION
53.Bl -tag -width ""
54.It Xo
55.Nm zfs
56.Cm mount
57.Xc
58Displays all ZFS file systems currently mounted.
59.It Xo
60.Nm zfs
61.Cm mount
62.Op Fl Oflv
63.Op Fl o Ar options
64.Fl a Ns | Ns Ar filesystem
65.Xc
66Mount ZFS filesystem on a path described by its
67.Sy mountpoint
68property, if the path exists and is empty.
69If
70.Sy mountpoint
71is set to
72.Em legacy ,
73the filesystem should be instead mounted using
74.Xr mount 8 .
75.Bl -tag -width "-O"
76.It Fl O
77Perform an overlay mount.
78Allows mounting in non-empty
79.Sy mountpoint .
80See
81.Xr mount 8
82for more information.
83.It Fl a
84Mount all available ZFS file systems.
85Invoked automatically as part of the boot process if configured.
86.It Ar filesystem
87Mount the specified filesystem.
88.It Fl o Ar options
89An optional, comma-separated list of mount options to use temporarily for the
90duration of the mount.
91See the
92.Em Temporary Mount Point Properties
93section of
94.Xr zfsprops 7
95for details.
96.It Fl l
97Load keys for encrypted filesystems as they are being mounted.
98This is equivalent to executing
99.Nm zfs Cm load-key
100on each encryption root before mounting it.
101Note that if a filesystem has
102.Sy keylocation Ns = Ns Sy prompt ,
103this will cause the terminal to interactively block after asking for the key.
104.It Fl v
105Report mount progress.
106.It Fl f
107Attempt to force mounting of all filesystems, even those that couldn't normally be mounted (e.g. redacted datasets).
108.El
109.It Xo
110.Nm zfs
111.Cm unmount
112.Op Fl fu
113.Fl a Ns | Ns Ar filesystem Ns | Ns Ar mountpoint
114.Xc
115Unmounts currently mounted ZFS file systems.
116.Bl -tag -width "-a"
117.It Fl a
118Unmount all available ZFS file systems.
119Invoked automatically as part of the shutdown process.
120.It Fl f
121Forcefully unmount the file system, even if it is currently in use.
122This option is not supported on Linux.
123.It Fl u
124Unload keys for any encryption roots unmounted by this command.
125.It Ar filesystem Ns | Ns Ar mountpoint
126Unmount the specified filesystem.
127The command can also be given a path to a ZFS file system mount point on the
128system.
