Will dedup ever be supported on ZFS/Solaris ? If not, will any possible problems be avoided if I remove (transfer data away from) any filesystems with dedup=on ? /PeO Prabahar Jeyaram skrev 2010-09-11 18:39:>> What, if you will use Zpools created with OSOL and Dedup on Solaris 10u9 >> > Not supported.

But then, who knows, perhaps Oracle will fix dedup and make it usable one day...

But then, who knows, perhaps Oracle will fix dedup and make it usable one day...Dedup changes large I/Os into small I/Os. If you expect dedup to change large I/Os into no I/Os, then you will be unhappy. Thus, the best solution for dedup is one which can handle large amounts of small I/Os. -- richard
