If you lose 1 vdev, you lose the pool. Doesn't matter what the redundancy level used in the vdev, if you lose more drives than the vdev can handle, you lose the whole pool. An easy way to remember this: - think of vdevs as harddrives - think of the pool as a RAID-0 stripeset Thus, if 1 drive dies, everything in the RAID-0 is lost. Similar for the pool. -- Freddie Cash fjwc...@gmail.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
