Destroys the given dataset.
|
||
|
|
By default, the command unshares any file systems that are currently shared,
|
||
|
|
unmounts any file systems that are currently mounted, and refuses to destroy a
|
||
|
|
dataset that has active dependents
|
||
|
|
.Pq children or clones .
|
||
|
|
.Bl -tag -width "-R"
|
||
|
|
.It Fl R
|
||
|
|
Recursively destroy all dependents, including cloned file systems outside the
|
||
|
|
target hierarchy.
|
||
|
|
.It Fl f
|
||
|
|
Force an unmount of any file systems using the
|
||
|
|
.Nm unmount Fl f
|
||
|
|
command.
|
||
|
|
This option has no effect on non-file systems or unmounted file systems.
|
||
|
|
.It Fl n
|
||
|
|
Do a dry-run
|
||
|
|
.Pq Qq No-op
|
||
|
|
deletion.
|
||
|
|
No data will be deleted.
|
||
|
|
This is useful in conjunction with the
|
||
|
|
.Fl v
|
||
|
|
or
|
||
|
|
.Fl p
|
||
|
|
flags to determine what data would be deleted.
|
||
|
|
.It Fl p
|
||
|
|
Print machine-parsable verbose information about the deleted data.
|
||
|
|
.It Fl r
|
||
|
|
Recursively destroy all children.
|
||
|
|
.It Fl v
|
||
|
|
Print verbose information about the deleted data.
|
||
|
|
.El
|
||
|
|
.Pp
|
||
|
|
Extreme care should be taken when applying either the
|
||
|
|
.Fl r
|
||
|
|
or the
|
||
|
|
.Fl R
|
||
|
|
options, as they can destroy large portions of a pool and cause unexpected
|
||
|
|
behavior for mounted file systems in use.

|

|
|
The given snapshots are destroyed immediately if and only if the
|
||
|
|
.Ql zfs destroy
|
||
|
|
command without the
|
||
|
|
.Fl d
|
||
|
|
option would have destroyed it.
|
||
|
|
Such immediate destruction would occur, for example, if the snapshot had no
|
||
|
|
clones and the user-initiated reference count were zero.
|
||
|
|
.Pp
|
||
|
|
If a snapshot does not qualify for immediate destruction, it is marked for
|
||
|
|
deferred deletion.
|
||
|
|
In this state, it exists as a usable, visible snapshot until both of the
|
||
|
|
preconditions listed above are met, at which point it is destroyed.
|
||
|
|
.Pp
|
||
|
|
An inclusive range of snapshots may be specified by separating the first and
|
||
|
|
last snapshots with a percent sign.
|
||
|
|
The first and/or last snapshots may be left blank, in which case the
|
||
|
|
filesystem's oldest or newest snapshot will be implied.
|
||
|
|
.Pp
|
||
|
|
Multiple snapshots
|
||
|
|
.Pq or ranges of snapshots
|
||
|
|
of the same filesystem or volume may be specified in a comma-separated list of
|
||
|
|
snapshots.
|
||
|
|
Only the snapshot's short name
|
||
|
|
.Po the part after the
|
||
|
|
.Sy @
|
||
|
|
.Pc
|
||
|
|
should be specified when using a range or comma-separated list to identify
|
||
|
|
multiple snapshots.
|
||
|
|
.Bl -tag -width "-R"
|
||
|
|
.It Fl R
|
||
|
|
Recursively destroy all clones of these snapshots, including the clones,
|
||
|
|
snapshots, and children.
|
||
|
|
If this flag is specified, the
|
||
|
|
.Fl d
|
||
|
|
flag will have no effect.
|
||
|
|
.It Fl d
|
||
|
|
Destroy immediately. If a snapshot cannot be destroyed now, mark it for
|
||
|
|
deferred destruction.
