== sanity-lfsck test 18d: Find out orphan OST-object and repair it (4) =============================== 16:03:13 (1477411393)
#####
The target MDT-object layout EA slot is occpuied by some new
created OST-object when repair dangling reference case. Such
conflict OST-object has never been modified. Then when found
the orphan OST-object, LFSCK will replace it with the orphan
OST-object.

Inject failure to make /mnt/lustre/d18d.sanity-lfsck/a1/f1 and /mnt/lustre/d18d.sanity-lfsck/a1/f2
to reference the same OST-object (which is f1's OST-obejct).
Then drop /mnt/lustre/d18d.sanity-lfsck/a1/f1 and its OST-object, so f2 becomes
dangling reference case, but f2's old OST-object is there.
