Just my 2c: Is it possible to do an "offline" dedup, kind of like snapshotting?
What I mean in practice, is: we make many Solaris full-root zones. They share a lot of data as complete files. This is kind of easy to save space - make one zone as a template, snapshot/clone its dataset, make new zones. However, as projects evolve (software installed, etc.) these zones are filled with many similar files, many of which are duplicates. It seems reasonable to make some dedup process which would create a least-common-denominator snapshot for all the datasets involved (zone roots), of which all other datasets' current data are to be dubbed "clones with modified data". For the system (and user) it should be perceived just the same as these datasets are currently "clones with modified data" of the original template zone-root dataset. Only the "template" becomes different... Hope this idea makes sense, and perhaps makes its way into code sometime :) This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
