I am under the impression that dedupe is still only in OpenSolaris and that support for dedupe is limited or non existent. Is this true? I would like to use ZFS and the dedupe capability to store multiple virtual machine images. The problem is that this will be in a production environment and would probably call for Solaris 10 instead of OpenSolaris. Are my statements on this valid or am I off track?

Dedup in OpenSolaris still seems risky to use other than for experimental purposes. It has only recently become available.

It has only recently become available.I''ve just wrote an entry about update 9, I think it will contain zpool version 19, so no dedup for this release if that''s correct.

A good place to review before you begin testing the new dedup features in the Nevada release is the ZFS dedup FAQ, which includes a list of known issues: http://hub.opensolaris.org/bin/view/Community+Group+zfs/dedup Thanks, Cindy On 01/05/10 08:38, Bob Friesenhahn wrote:> On Mon, 4 Jan 2010, Tony Russell wrote: > >> I am under the impression that dedupe is still only in OpenSolaris and >> that support for dedupe is limited or non existent.
