ZFS-RENAME(8)		     System Manager's Manual		   ZFS-RENAME(8)

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  snap-
       shot,  the  parent file system of the snapshot does not need to be speci-
       fied 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
