    Description

      Server 2.7.59
      Client 2.7.59
      Reproducible.
      Configuration : quartet

      == sanity-lfsck test 23b: LFSCK can repair dangling name entry (2) == 05:43:26 (1441691006)
      #####
      The objectA has multiple hard links, one of them corresponding
      to the name entry_B. But there is something wrong for the name
      entry_B and cause entry_B to references non-exist object_C.
      In the first-stage scanning, the LFSCK will think the entry_B
      as dangling, and re-create the lost object_C. When the LFSCK
      comes to the second-stage scanning, it will find that the
      former re-creating object_C is not proper, and will try to
      replace the object_C with the real object_A.
      #####
      Inject failure stub on MDT0 to simulate dangling name entry

      'ls' should fail because of dangling name entry
      Trigger namespace LFSCK to find out dangling name entry
