If c0t6d0 and c0t7d0 both fail (ie both sides of the same mirror vdev) then the pool will be unable to retrieve all the data stored in it. If c0t6d0 and c0t3d0 both fail then there are sufficient replicas of data available in that case because it was disks from different mirrors. This applies to SVM as well if you have a stripe of mirrors with a UFS filesystem ontop of that you will have the same availability issue. -- Darren J Moffat _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
