[LU-9827] sanityn fail “remove sub-test dirs failed d80b.sanityn/migrate_dir”

Related — Thu, 24 Aug 2023 17:38:21 +0000

The sanityn test suite fails, but no subtests fail. If you look at the end of the suite_stdout log, we see that one of the directories that test_80b created cannot be deleted

03:30:00:== sanityn test complete, duration 3688 sec ========================================================== 03:29:56 (1501730996)

test 80b does not fail, but we see the following in the test_log:

We’ve seen this test suite failure with a Lustre setup with DNE:
