870fc32f | 44 | .Sh DESCRIPTION |
870fc32f | 45 | The |
f84fe3fc | 46 | .Nm zfs Cm promote |
b46be903 DS |
47 | command makes it possible to destroy the dataset that the clone was created |
48 | from. | |
870fc32f | 49 | The clone parent-child dependency relationship is reversed, so that the origin |
f84fe3fc | 50 | dataset becomes a clone of the specified dataset. |
870fc32f RW |
51 | .Pp |
52 | The snapshot that was cloned, and any snapshots previous to this snapshot, are | |
53 | now owned by the promoted clone. | |
f84fe3fc | 54 | The space they use moves from the origin dataset to the promoted clone, so |
870fc32f RW |
55 | enough space must be available to accommodate these snapshots. |
56 | No new space is consumed by this operation, but the space accounting is | |
57 | adjusted. | |
58 | The promoted clone must not have any conflicting snapshot names of its own. | |
59 | The | |
f84fe3fc | 60 | .Nm zfs Cm rename |
870fc32f | 61 | subcommand can be used to rename any conflicting snapshots. |

64 | .\" These are, respectively, examples 10 from zfs.8 | |
65 | .\" Make sure to update them bidirectionally | |
66 | .Ss Example 1 : No Promoting a ZFS Clone | |
67 | The following commands illustrate how to test out changes to a file system, and | |
68 | then replace the original file system with the changed one, using clones, clone | |
69 | promotion, and renaming: | |
70 | .Bd -literal -compact -offset Ds | |
71 | .No # Nm zfs Cm create Ar pool/project/production | |
72 | populate /pool/project/production with data | |
73 | .No # Nm zfs Cm snapshot Ar pool/project/production Ns @ Ns Ar today | |
74 | .No # Nm zfs Cm clone Ar pool/project/production@today pool/project/beta | |
75 | make changes to /pool/project/beta and test them | |
76 | .No # Nm zfs Cm promote Ar pool/project/beta | |
77 | .No # Nm zfs Cm rename Ar pool/project/production pool/project/legacy | |
78 | .No # Nm zfs Cm rename Ar pool/project/beta pool/project/production | |
79 | once the legacy version is no longer needed, it can be destroyed | |
80 | .No # Nm zfs Cm destroy Ar pool/project/legacy | |
