| .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. |
