Feature #1645
closed
add ZFS "written" and "written@..." properties
0%
Description
Add a new property, "written", and dynamic property family, "written@<snapshot>", to determine how much space was written to a filesystem or snapshot relative to a previous snapshot.
manpage changes:
written
The amount of referenced space written to this dataset
since the previous snapshot.written@snapshot
The amount of referenced space written to this dataset
since the specified snapshot. This is the space that is
referenced by this dataset but was not referenced by the
specified snapshot.The snapshot may be specified as a short snapshot name
(just the part after the @), in which case it will be
interpreted as a snapshot in the same filesystem as
this dataset. The snapshot be a full snapshot name
(filesystem@snapshot), which for clones may be a
snapshot in the origin's filesystem (or the origin of
the origin's filesystem, etc).
examples:
$ zfs list -t all -o name,used,written NAME USED WRITTEN ... rpool/versions/2011.08.11.00/running 299M 31K rpool/versions/2011.08.11.00/running/svc 37.0M 0 rpool/versions/2011.08.11.00/running/svc@2011.08.12.00 4.53M 14.4M rpool/versions/2011.08.11.00/running/svc@2011.08.15.00 4.53M 9.04M rpool/versions/2011.08.11.00/running/svc@2011.08.19.00 0 13.5M rpool/versions/2011.08.11.00/running/var 262M 0 rpool/versions/2011.08.11.00/running/var@2011.08.12.00 79.6M 81.5M rpool/versions/2011.08.11.00/running/var@2011.08.15.00 80.3M 94.6M rpool/versions/2011.08.11.00/running/var@2011.08.19.00 0 85.6M $ zfs get -r written@2011.08.12.00 rpool/versions/2011.08.11.00/running NAME PROPERTY VALUE SOURCE rpool/versions/2011.08.11.00/running written@2011.08.12.00 - - rpool/versions/2011.08.11.00/running/svc written@2011.08.12.00 18.0M local rpool/versions/2011.08.11.00/running/svc@2011.08.12.00 written@2011.08.12.00 0 local rpool/versions/2011.08.11.00/running/svc@2011.08.15.00 written@2011.08.12.00 9.04M local rpool/versions/2011.08.11.00/running/svc@2011.08.19.00 written@2011.08.12.00 18.0M local rpool/versions/2011.08.11.00/running/var written@2011.08.12.00 99.9M local rpool/versions/2011.08.11.00/running/var@2011.08.12.00 written@2011.08.12.00 0 local rpool/versions/2011.08.11.00/running/var@2011.08.15.00 written@2011.08.12.00 94.6M local rpool/versions/2011.08.11.00/running/var@2011.08.19.00 written@2011.08.12.00 99.9M local
