Also, if ZFS decides that a block is bad, it can leave it unused. For example, if you have a mirrored pool, it is not required that block N on vdev1 == block N on vdev2. In a sense, this works like block sparing. Regarding SMART, there is much discussion on this in the archives. In a nutshell, there are FMA modules which use SMART data. There are a few tools which allow an administrator to see SMART data. Some question whether SMART data is actually useful. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
