41.Cm mount
42.Nm zfs
43.Cm mount
44.Op Fl Oflv
45.Op Fl o Ar options
46.Fl a Ns | Ns Fl R Ar filesystem Ns | Ns Ar filesystem

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 Fl R Ar filesystem 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 Fl R
87Mount the specified filesystems along with all their children.
88.It Ar filesystem
89Mount the specified filesystem.
90.It Fl o Ar options
91An optional, comma-separated list of mount options to use temporarily for the
92duration of the mount.
93See the
94.Em Temporary Mount Point Properties
95section of
96.Xr zfsprops 7
97for details.
98.It Fl l
99Load keys for encrypted filesystems as they are being mounted.
100This is equivalent to executing
101.Nm zfs Cm load-key
102on each encryption root before mounting it.
103Note that if a filesystem has
104.Sy keylocation Ns = Ns Sy prompt ,
105this will cause the terminal to interactively block after asking for the key.
106.It Fl v
107Report mount progress.
108.It Fl f
109Attempt to force mounting of all filesystems, even those that couldn't normally
110be mounted (e.g. redacted datasets).
111.El
112.It Xo
113.Nm zfs
114.Cm unmount
115.Op Fl fu
116.Fl a Ns | Ns Ar filesystem Ns | Ns Ar mountpoint
117.Xc
118Unmounts currently mounted ZFS file systems.
119.Bl -tag -width "-a"
120.It Fl a
121Unmount all available ZFS file systems.
122Invoked automatically as part of the shutdown process.
123.It Fl f
124Forcefully unmount the file system, even if it is currently in use.
125This option is not supported on Linux.
126.It Fl u
127Unload keys for any encryption roots unmounted by this command.
128.It Ar filesystem Ns | Ns Ar mountpoint
129Unmount the specified filesystem.
130The command can also be given a path to a ZFS file system mount point on the
131system.
