|
|
|
.Nm zfs Cm promote
|
2022-11-12 15:23:30 +03:00
|
|
|
command makes it possible to destroy the dataset that the clone was created
|
|
|
|
from.
|
2019-11-12 22:17:40 +03:00
|
|
|
The clone parent-child dependency relationship is reversed, so that the origin
|
2021-05-27 03:46:40 +03:00
|
|
|
dataset becomes a clone of the specified dataset.
|
2019-11-12 22:17:40 +03:00
|
|
|
.Pp
|
|
|
|
The snapshot that was cloned, and any snapshots previous to this snapshot, are
|
|
|
|
now owned by the promoted clone.
|
2021-05-27 03:46:40 +03:00
|
|
|
The space they use moves from the origin dataset to the promoted clone, so
|
2019-11-12 22:17:40 +03:00
|
|
|
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 following commands illustrate how to test out changes to a file system, and
|
|
|
|
then replace the original file system with the changed one, using clones, clone
|
|
|

promotion, and renaming:
