Well, no, not really. It all depends on the number of sets and the MTTR. Consider the case where you have 1 set of raidz3 and 2 sets of 3-way mirrors. The raidz3 set can only stand to lose 3 disks where the mirrored sets can stand to lose 4 disks. The answer is not immediately intuitive because it does depend on the MTTR for practical cases. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
