Description

sanity test_59 fails in wait_delete_completed_mds() with “test_59 failed with 1” for review-dne-zfs-part-1 only.

sanity test 59 is a simple test that creates 130 files, unlinks the files and waits for 20 seconds, by default, until all osc.*MDT*.sync_* parameters are zero.

Looking at the suite_log for https://testing.whamcloud.com/test_sets/299f3fba-358b-11e9-ae87-52540065bddc , we see that the sync parameters are not all zero for all MDSs within 28 seconds; some parameters that are zero are removed from the following output and replaced with “…”

Delete is not completed in 28 seconds

 sanity test_59: @@@@@@ FAIL: test_59 failed with 1 

There are no errors or other indication of a problem in the console logs.

Note: We should check the return code of wait_delete_completed() and call error() when the return code is anything other than 0 to make the error message more descriptive/helpful.
