NAME
zfs-rename — rename ZFS dataset
SYNOPSIS
zfs rename [-f] filesystem|volume|snapshot filesystem|volume|snapshot
zfs rename -p [-f] filesystem|volume filesystem|volume
zfs rename -u [-f] filesystem filesystem
zfs rename -r snapshot snapshot
DESCRIPTION
zfs rename [-f] filesystem|volume|snapshot filesystem|volume|snapshot
zfs rename -p [-f] filesystem|volume filesystem|volume
zfs rename -u [-f] filesystem filesystem
Renames the given dataset. The new target can be located anywhere in the ZFS hierarchy, with the
exception of snapshots. Snapshots can only be renamed within the parent file system or volume. When
renaming a snapshot, the parent file system of the snapshot does not need to be specified as part of
the second argument. Renamed file systems can inherit new mount points, in which case they are
unmounted and remounted at the new mount point.
-f Force unmount any file systems that need to be unmounted in the process. This flag has no effect
if used together with the -u flag.
-p Creates all the nonexistent parent datasets. Datasets created in this manner are automatically
mounted according to the mountpoint property inherited from their parent.
-u Do not remount file systems during rename. If a file system's mountpoint property is set to legacy
or none, the file system is not unmounted even if this option is not given.
zfs rename -r snapshot snapshot
Recursively rename the snapshots of all descendent datasets. Snapshots are the only dataset that can
be renamed recursively.
EXAMPLES
Example 1: Promoting a ZFS Clone
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:
# zfs create pool/project/production
populate /pool/project/production with data
# zfs snapshot pool/project/production@today
# zfs clone pool/project/production@today pool/project/beta
make changes to /pool/project/beta and test them
# zfs promote pool/project/beta
# zfs rename pool/project/production pool/project/legacy
# zfs rename pool/project/beta pool/project/production
once the legacy version is no longer needed, it can be destroyed
# zfs destroy pool/project/legacy
Example 2: Performing a Rolling Snapshot
The following example shows how to maintain a history of snapshots with a consistent naming scheme. To
keep a week's worth of snapshots, the user destroys the oldest snapshot, renames the remaining snapshots,
and then creates a new snapshot, as follows:
# zfs destroy -r pool/users@7daysago
# zfs rename -r pool/users@6daysago @7daysago
# zfs rename -r pool/users@5daysago @6daysago
# zfs rename -r pool/users@4daysago @5daysago
# zfs rename -r pool/users@3daysago @4daysago
# zfs rename -r pool/users@2daysago @3daysago
# zfs rename -r pool/users@yesterday @2daysago
# zfs rename -r pool/users@today @yesterday
# zfs snapshot -r pool/users@today
