Disks are made of chemicals, which can degrade over time. If some part of a disk starts to deteriorate, but you never attempt to read it, then you'll never know it's going bad. You should have redundancy, and scrub on a regular basis, much more frequently than the occurrence of a disk going bad - maybe once a week or once a month. If you can afford to scrub daily, that's great. Depending on your system and your data, scrubs might take several hours, thus making it impractical to scrub daily. _______________________________________________ zfs-discuss mailing list firstname.lastname@example.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
