Hi all Has anyone done any testing with dedup with OI? On opensolaris there is a nifty "feature" that allows the system to hang for hours or days if attempting to delete a dataset on a deduped pool. This is said to be fixed, but I haven''t seen that myself, so I''m just wondering... I''ll get a 10TB test box released for testing OI in a few weeks, but before than, has anyone tested this?

AFAIK that part of dedup code is not changed in b147. On Sat, Sep 25, 2010 at 6:54 PM, Roy Sigurd Karlsbakk <roy at karlsbakk.net> wrote:> Hi all > > Has anyone done any testing with dedup with OI?

Also performance is a lot better. Yours Markus Kovero
