== sanity-lfsck test 24: LFSCK can repair multiple-referenced name entry ========================================================== 05:05:05 (1713431105)
#####
Two MDT-objects back reference the same name entry via their
each own linkEA entry, but the name entry only references one
MDT-object. The namespace LFSCK will remove the linkEA entry
for the MDT-object that is not recognized. If such MDT-object
has no other linkEA entry after the removing, then the LFSCK
will add it as orphan under the .lustre/lost+found/MDTxxxx/.

Inject failure stub on MDT0 to simulate the case that
the /mnt/lustre/d24.sanity-lfsck/d0/dummy/foo has the 'bad' linkEA entry
that references /mnt/lustre/d24.sanity-lfsck/d0/guard/foo.
Then remove the name entry /mnt/lustre/d24.sanity-lfsck/d0/dummy/foo.
So the MDT-object /mnt/lustre/d24.sanity-lfsck/d0/dummy/foo will be left
there with the same linkEA entry as another MDT-object
/mnt/lustre/d24.sanity-lfsck/d0/guard/foo has
