Do both RAID-Z and Mirror redundancy use checksums on ZFS? Or just RAID-Z?

And if you're concerned with the integrity of the data, why not use some ZFS redundancy? (I'm guessing you're applying the redundancy further downstream; but, as this situation demonstrates, separating it too far from the checksum verification makes it less useful.) -- David Dyer-Bennet, <mailto:[EMAIL PROTECTED]>, <http://www.dd-b.net/dd-b/> RKBA: <http://www.dd-b.net/carry/> Pics: <http://www.dd-b.net/dd-b/SnapshotAlbum/> Dragaera/Steven Brust: <http://dragaera.info/> _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
