|

.Os
|
|
.
|
|
.Sh NAME
|
|
.Nm zfs-promote
|
|
.Nd promote clone dataset to no longer depend on origin snapshot
|
|
.Sh SYNOPSIS
|
|
.Nm zfs
|
|
.Cm promote
|
|
.Ar clone
|
|
.
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm zfs Cm promote
|
|
command makes it possible to destroy the dataset that the clone was created from.
|
|
The clone parent-child dependency relationship is reversed, so that the origin
|
|
dataset becomes a clone of the specified dataset.
|
|
.Pp
|
|
The snapshot that was cloned, and any snapshots previous to this snapshot, are
|
|
now owned by the promoted clone.
|
|
The space they use moves from the origin dataset to the promoted clone, so
|
|
enough space must be available to accommodate these snapshots.
|
|
No new space is consumed by this operation, but the space accounting is
|
|
adjusted.
|
|
The promoted clone must not have any conflicting snapshot names of its own.
|
|
The
|
|
.Nm zfs Cm rename
|
|
subcommand can be used to rename any conflicting snapshots.
