== sanity-lfsck test 18d: Find out orphan OST-object and repair it (4) ========================================================== 05:09:29 (1713344969)
#####
The target MDT-object layout EA is corrupted, but the right
OST-object is still alive as orphan. The layout LFSCK will
not create new OST-object to occupy such slot.

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.
The failure also makes /mnt/lustre/d18d.sanity-lfsck/a1/f3 and /mnt/lustre/d18d.sanity-lfsck/a1/f4
to reference the same OST-object (which is f3's OST-obejct).
Then drop /mnt/lustre/d18d.sanity-lfsck/a1/f3 and its OST-object, so f4 becomes
dangling reference case, but f4's old OST-object is there.

Trigger layout LFSCK on all devices to find out orphan OST-object
Started LFSCK on the device lustre-MDT0000: scrub layout
The file size should be correct after layout LFSCK scanning
The LFSCK should find back the original data.
