sanity test_57b: MDC before 382704 != after 382680

Bug Minor Resolved Duplicate Jian Yu Maloo Wed, 14 Jun 2017 01:26:45 +0000 Wed, 14 Jul 2021 21:05:35 +0000 Mon, 26 Mar 2018 05:31:36 +0000 Lustre 2.10.0 0 5 <p>Jian</p> <p>can you please investigate?</p> <p>Thanks</p> <p>Peter</p> <p>Hi Saurabh,<br/> I saw the configuration was 1 MGT/MDT, 1 OST and 1 Client. Did the same test pass before during rolling upgrade testing with the same configuration?<br/> Many tests required at least 2 OSTs. Some of them have codes to check the OST count, and some do not have such codes, which will fail with 1 OST (e.g., sanity test 27F failed with 1 OST) instead of skipping the test.</p> <p>Yes, the same test did pass before for rolling upgrade/downgrade testing with the same config. Here are the results for the last successful run:<br/> <a href="https://testing.hpdd.intel.com/test_sessions/977f2f34-1e29-11e7-9de9-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sessions/977f2f34-1e29-11e7-9de9-5254006e85c2</a></p> <p>Thank you Saurabh for the info. The above passed session used physical server nodes instead of vm nodes and had much larger server target device size. Is there any successful test session also using vm server nodes?<br/> If yes, I'm going to reproduce the failure and find out the root cause.</p> <p>BTW, could you please run the tests with at least 2 OSTs in the future so as to avoid some configuration test failures?</p> <p>I don't have them on vms and yes you are right may be that can be the issue. And I will make sure I use 2 OSTs .</p> <p>Thank you Saurabh.<br/> Could you please re-run the tests with 2 OSTs and larger device size? (many tests in the test session failed with out of space issue)</p> <p>Yeah sure, I will do that.<br/> Thanks for looking into the issues.</p> <p>We should improve the test scripts with checking OST count to avoid this kind of failure. I will open a ticket- <a href="https://jira.whamcloud.com/browse/LU-9677" title="Checking OST counts in test suites where needed" class="issue-link" data-issue-key="LU-9677">LU-9677</a></p> <p>Thank you, Sarah.</p> <p>The test script will be improved in <a href="https://jira.whamcloud.com/browse/LU-9677" title="Checking OST counts in test suites where needed" class="issue-link" data-issue-key="LU-9677">LU-9677</a>.</p> Duplicate LU-9677 Related LU-4109 LU-9677 Development Rank 1|hzzf1r: Rank (Obsolete) 9223372036854775807 Severity
