You are confusing unrecoverable disk errors (which are rare but orders of magnitude more common) with otherwise *undetectable* errors (the occurrence of which is at most once in petabytes by the studies I've seen, rather than once in terabytes), despite my attempt to delineate the difference clearly. Conventional approaches using scrubbing provide as complete protection against unrecoverable disk errors as ZFS does: it's only the far rarer otherwise *undetectable* errors that ZFS catches and they don't. - bill This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
