I'm not against fixing the test to not have assumptions about the test environment, but the other test should also be fixed not to change the global filesystem defaults in the middle of the test run. </p> <p><a href="https://testing.whamcloud.com/test_sessions/6ff51064-1eac-40b4-997f-bc6fcf59607a" class="external-link" target="_blank" rel="nofollow noopener">https://testing.whamcloud.com/test_sessions/6ff51064-1eac-40b4-997f-bc6fcf59607a</a></p> <p>+1 on master <a href="https://testing.whamcloud.com/test_sets/220ac885-cdcd-42f9-bd09-3c1160c27945" class="external-link" target="_blank" rel="nofollow noopener">https://testing.whamcloud.com/test_sets/220ac885-cdcd-42f9-bd09-3c1160c27945</a></p> <p>The original commit adding test_51d was:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>Branch b1_4 Description: Inefficient object allocation for multi-stripe files Details : When selecting which OSTs to stripe files over, for files with a stripe count that divides evenly into the number of OSTs, the MDS is always picking the same starting OST for each file. Return the OST selection heuristic to the original design. Also make these variables per-LOV for the case of multiple MDTs on the same node and add sanity.sh test 51d to verify. b=10671 </pre> </div></div> <p>I think a core problem with the test is that if the OSTs are imbalanced and QOS is used, then the starting OST allocation will also be imbalanced, causing the test to intermittently fail. Either it should explicitly disable QOS before the start of the test (<tt>&#42;.&#42;.qos_threshold=100</tt>, account for the OST imbalance, or just be more forgiving in the thresholds.</p> <p>"Andreas Dilger &lt;adilger@whamcloud.com&gt;" uploaded a new patch: <a href="https://review.whamcloud.com/44762" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/44762</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12058" title="sanity test_51d: @@@@@@ FAIL: OST 1 has less #0 objects vs OST 0 (0 &lt; 1000" class="issue-link" data-issue-key="LU-12058"><del>LU-12058</del></a> tests: improve sanity test_51d reliability<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 0844979ef274be7269ab2be98db7815c352ebe1f</p> <p>"Oleg Drokin &lt;green@whamcloud.com&gt;" merged in patch <a href="https://review.whamcloud.com/44762/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/44762/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12058" title="sanity test_51d: @@@@@@ FAIL: OST 1 has less #0 objects vs OST 0 (0 &lt; 1000" class="issue-link" data-issue-key="LU-12058"><del>LU-12058</del></a> tests: improve sanity test_51d reliability<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 2e832a0038af7f3d9f022beb862578988592d682</p> <p>Landed for 2.15</p> Duplicate LU-14745 Related LU-8933 LU-9506 Development Rank 1|i00d3z: Rank (Obsolete) 9223372036854775807 Severity
