zfs-promote —
promote clone dataset to no longer depend on origin
snapshot
zfs |
promote clone |
The zfs 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.
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 zfs
rename subcommand can be used to rename any
conflicting snapshots.
