[LU-13967] Tests fail/hang with “can't notify - lge_glbl_data is not set”

Fri, 25 Sep 2020 04:00:57 +0000

We are seeing the message

(qmt_entry.c:805:qmt_adjust_edquot_qunit_notify()) lustre-QMT0000: can't notify - lge_glbl_data is not set

in the MDS console log for many test suites starting on 19 AUG 2020. This message was introduced by "~~LU-11023~~ quota: quota pools for OSTs" with patch commit 09f9fb3211cd .

Some tests like sanity-pcc test 5 at https://testing.whamcloud.com/test_sets/b8d571f0-46fe-4651-a545-24c8142eebf8 fail or hang after this comment is printed, but it’s not clear if the statement is actually warning of a real problem or if the tests are failing/hanging for a different reason.

For the test session https://testing.whamcloud.com/test_sessions/42070a37-3493-47fe-a89f-5b0d4c869bb8, we see messages like the following seven times in the MDS console log:

[31796.773626] Lustre: format at qmt_entry.c:805:qmt_adjust_edquot_qunit_notify doesn't end in newline

We need to determine if this message is a sign of a real problem of if it should be suppressed.
