Run a scrub once a week or once or twice a month. What else do you mean by "smart"? You could add a third disk and label it a spare. Or you could add a third disk and make it a 3-way mirror. You should create zfs in the zpool, so you can do snapshots. -dsr- _______________________________________________ Discuss mailing list Discuss@lists.blu.org http://lists.blu.org/mailman/listinfo/discuss
