36.Sh NAME
37.Nm zfs-promote
38.Nd promote clone dataset to no longer depend on origin snapshot
39.Sh SYNOPSIS
40.Nm zfs
41.Cm promote
42.Ar clone
43.
44.Sh DESCRIPTION
45The
46.Nm zfs Cm promote
47command makes it possible to destroy the dataset that the clone was created from.
48The clone parent-child dependency relationship is reversed, so that the origin
49dataset becomes a clone of the specified dataset.
50.Pp
51The snapshot that was cloned, and any snapshots previous to this snapshot, are
52now owned by the promoted clone.
53The space they use moves from the origin dataset to the promoted clone, so
54enough space must be available to accommodate these snapshots.
55No new space is consumed by this operation, but the space accounting is
56adjusted.
57The promoted clone must not have any conflicting snapshot names of its own.
58The
59.Nm zfs Cm rename
60subcommand can be used to rename any conflicting snapshots.
