[LU-5184] sanity-lfsck test 18d: file size never checked

• Type: Bug

Description

After creating a dangling reference, sanity-lfsck test 18d checks a file's size to make sure that there is an inconsistency. From test_18d:

	echo "The file size should be incorrect since dangling referenced"
	local cur_size=$(ls -il $DIR/$tdir/a1/f2 | awk '{ print $6 }')
	[ "$cur_size" != "$saved_size" ] ||
		error "(1) Expect incorrect file2 size"

but, when there is a dangling reference, ls does not return the file size. From the output of test_18d:

The file size should be incorrect since dangling referenced
ls: cannot access /lustre/scratch/d18d.sanity-lfsck/a1/f2: Cannot allocate memory

Thus, the file size is never checked and this code does not do what is intended. This check needs to be rethought; it should probably be taken out or a different failure other than dangling reference needs to be injected here.
