Abstract: A system and method for conforming a metadata file associated with qtree of a storage system to a version used by a file system kernel of the storage system, where the version indicates a format of the metadata file. The metadata file stores state information with respect to each qtree, and may be located outside of the qtree structure. Major and minor versions are compared with latest known major and minor versions associated with the file system kernel. In response to such comparisons, the metadata file may be updated to a newer version, rolled back to an older version, and/or the system may enter a corrective state where further operations are performed.

Abstract: A lance tip assembly for a water-cooled lance as well as a method for constructing same. The lance tip assembly includes a first component of solid cast metal which is secured to a second or lower component of forged metal. Each active material discharge nozzle of the combined forged and cast lance tip assembly is constructed in part of the first cast component and in part of the second forged component. Only a single bond is required to join the first and second component at each nozzle site. The first and second components are fabricated to include structural features which individually and collectively promote high coolant water flow velocity through the lance tip and substantially uniform cooling of face of the lance tip.
