      Description

      This ticket relates to handling of OST orphan cleanup. This includes:

      • create an in-memory bitmap for OST FIDs that have been referenced during MDS Pass 1 checking
      • after the OST Pass 2 scanning is complete, any OST objects that have not been referenced need to be verified with the MDT, and added to lost+found or unlinked (depending on administrator preference)
