53.Sh DESCRIPTION
54.Bl -tag -width ""
55.It Xo
56.Nm zfs
57.Cm mount
58.Op Fl j
59.Xc
60Displays all ZFS file systems currently mounted.
61.Bl -tag -width "-j"
62.It Fl j , -json
63Displays all mounted file systems in JSON format.

65.It Xo
66.Nm zfs
67.Cm mount
68.Op Fl Oflv
69.Op Fl o Ar options
70.Fl a Ns | Ns Fl R Ar filesystem Ns | Ns Ar filesystem
71.Xc
72Mount ZFS filesystem on a path described by its
73.Sy mountpoint
74property, if the path exists and is empty.
75If
76.Sy mountpoint
77is set to
78.Em legacy ,
79the filesystem should be instead mounted using
80.Xr mount 8 .
81.Bl -tag -width "-O"
82.It Fl O
83Perform an overlay mount.
84Allows mounting in non-empty
85.Sy mountpoint .
86See
87.Xr mount 8
88for more information.
89.It Fl a
90Mount all available ZFS file systems.
91Invoked automatically as part of the boot process if configured.
92.It Fl R
93Mount the specified filesystems along with all their children.
94.It Ar filesystem
95Mount the specified filesystem.
96.It Fl o Ar options
97An optional, comma-separated list of mount options to use temporarily for the
98duration of the mount.
99See the
100.Em Temporary Mount Point Properties
101section of
102.Xr zfsprops 7
103for details.
104.It Fl l
105Load keys for encrypted filesystems as they are being mounted.
106This is equivalent to executing
107.Nm zfs Cm load-key
108on each encryption root before mounting it.
109Note that if a filesystem has
110.Sy keylocation Ns = Ns Sy prompt ,
111this will cause the terminal to interactively block after asking for the key.
112.It Fl v
113Report mount progress.
114.It Fl f
115Attempt to force mounting of all filesystems, even those that couldn't normally
116be mounted (e.g. redacted datasets).
117.El
118.It Xo
119.Nm zfs
120.Cm unmount
121.Op Fl fu
122.Fl a Ns | Ns Ar filesystem Ns | Ns Ar mountpoint
123.Xc
124Unmounts currently mounted ZFS file systems.
125.Bl -tag -width "-a"
126.It Fl a
127Unmount all available ZFS file systems.
128Invoked automatically as part of the shutdown process.
129.It Fl f
130Forcefully unmount the file system, even if it is currently in use.
131This option is not supported on Linux.
132.It Fl u
133Unload keys for any encryption roots unmounted by this command.
134.It Ar filesystem Ns | Ns Ar mountpoint
135Unmount the specified filesystem.
136The command can also be given a path to a ZFS file system mount point on the
137system.
