55.Bl -tag -width ""
56.It Xo
57.Nm zfs
58.Cm mount
59.Op Fl j
60.Xc
61Displays all ZFS file systems currently mounted.
62.Bl -tag -width "-j"
63.It Fl j , -json
64Displays all mounted file systems in JSON format.

66.It Xo
67.Nm zfs
68.Cm mount
69.Op Fl Oflv
70.Op Fl o Ar options
71.Fl a Ns | Ns Fl R Ar filesystem Ns | Ns Ar filesystem
72.Xc
73Mount ZFS filesystem on a path described by its
74.Sy mountpoint
75property, if the path exists and is empty.
76If
77.Sy mountpoint
78is set to
79.Em legacy ,
80the filesystem should be instead mounted using
81.Xr mount 8 .
82.Bl -tag -width "-O"
83.It Fl O
84Perform an overlay mount.
85Allows mounting in non-empty
86.Sy mountpoint .
87See
88.Xr mount 8
89for more information.
90.It Fl a
91Mount all available ZFS file systems.
92Invoked automatically as part of the boot process if configured.
93.It Fl R
94Mount the specified filesystems along with all their children.
95.It Ar filesystem
96Mount the specified filesystem.
97.It Fl o Ar options
98An optional, comma-separated list of mount options to use temporarily for the
99duration of the mount.
100See the
101.Em Temporary Mount Point Properties
102section of
103.Xr zfsprops 7
104for details.
105.It Fl l
106Load keys for encrypted filesystems as they are being mounted.
107This is equivalent to executing
108.Nm zfs Cm load-key
109on each encryption root before mounting it.
110Note that if a filesystem has
111.Sy keylocation Ns = Ns Sy prompt ,
112this will cause the terminal to interactively block after asking for the key.
113.It Fl v
114Report mount progress.
115.It Fl f
116Attempt to force mounting of all filesystems, even those that couldn't normally
117be mounted (e.g. redacted datasets).
118.El
119.It Xo
120.Nm zfs
121.Cm unmount
122.Op Fl fu
123.Fl a Ns | Ns Ar filesystem Ns | Ns Ar mountpoint
124.Xc
125Unmounts currently mounted ZFS file systems.
126.Bl -tag -width "-a"
127.It Fl a
128Unmount all available ZFS file systems.
129Invoked automatically as part of the shutdown process.
130.It Fl f
131Forcefully unmount the file system, even if it is currently in use.
132This option is not supported on Linux.
133.It Fl u
134Unload keys for any encryption roots unmounted by this command.
135.It Ar filesystem Ns | Ns Ar mountpoint
136Unmount the specified filesystem.
137The command can also be given a path to a ZFS file system mount point on the
138system.
