The new issue is created at LU-9597.

I think the old issue should have been fixed once the LU-2435 being landed, we can re-enable test_33 for zfs testing now, I'll cook a patch to re-enable it.

The new occurrences on ldiskfs is another issue, I believe it's a defect in project quota:

sanity-quota test_33: @@@@@@ FAIL: Used space for project 1000:18432, expected:20480

I think we'd open a new ticket for it.

I don't think skipping the test is the right way forward, except as a short-term workaround. Instead, someone needs to take the time to figure out what file is being left behind with this UID.

being seen in non-zfs tests too. example:
https://testing.hpdd.intel.com/test_sets/834ddd66-472e-11e7-b3fe-5254006e85c2

I note that test 33 is skipped with ALWAYS_EXCEPT for test runs on zfs. Maybe it needs to be skipped all the time on everything.

[Andreas Dilger]

There is a belief that this was caused by slow ZFS metadata performance, which has been improved in Lustre 2.9. It would be worthwhile to retest these skipped tests (with ZFS of course) to see if they now pass reliably.

[James Nunez (Inactive)]

This issue is not resolved. Only a patch to skip the tests was landed. The original problem causing sanity-quota 11, 33, 34, and 35 still exists.

Landed for 2.8
