Well, neither one of the above statements is really fair. The truth is: radi5/6 are generally not that bad. Data integrity failures are not terribly common (maybe one bit per year out of 20 large disks or something like that.) And in order to reach the conclusion "nobody would use it," the people using it would have to first *notice* the failure. Which they don't. That's kind of the point. Since I started using ZFS in production, about a year ago, on three servers totaling approx 1.5TB used, I have had precisely one checksum error, which ZFS corrected. I have every reason to believe, if that were on a raid5/6, the error would have gone undetected and nobody would have noticed. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
