I know any of the ways will *work*. (Or can be made to.) I'm just asking for the wisdom and the opinions of the internets on whether anything could be considered 'better'. So: Thanks for your thoughts. (One note: Loss of the ZIL drive should not be a problem under the patched ZFS. As of ZFS v19, the ZIL can be lost or removed without affecting the filesystem. Prior to that once you had defined a ZIL drive you needed to always have a working ZIL drive.) Daniel T.
