If I cared that much about fault tolerance then I'd be running one 4-way mirror instead of two 2-way mirrors. As is, if I lose two drives out of the four before I can replace and resilver one, all I'm really out is the most recent backups of my daily drivers and the time needed to restore my backups which are kept on auxiliary storage. -- \m/ (--) \m/ _______________________________________________ Discuss mailing list Discuss@lists.blu.org http://lists.blu.org/mailman/listinfo/discuss
