I want zfs on a single drive so I use copies=2 for -some- extra safety. But I wonder if dedup=on could mean something in this case too? That way the same blocks would never be written more than twice. Or would that harm the reliability of the drive and should I just use copies=2? -- Dick Hoogendijk -- PGP/GnuPG key: 01D2433D + nagual.nl | OpenSolaris 2010.03 b131 + All that''s really worth doing is what we do for others (Lewis Carrol)
