Is there any reason why you don't want to use striped mirrors (i.e. stripes of mirrored vdevs, a.k.a raid 10) with online spares? This should provide high level of availability while greatly reducing downtime needed for resilvering in the event of disk failure. And if you're REALLY paranoid you could go with 3-way or more mirror for each vdevs. Regards, Fajar _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
