    Description

      There at occasions where the OI file can become corrupted (e.g. double mount of a filesystem), or otherwise need to be rebuilt (e.g. upgrade of normal ZFS filesystem to Lustre MDT in the future). It would be useful to be able to verify and/or rebuild the ZFS OI files during dnode iteration.
