sanity test_160j: FAIL: read changelog failed

Bug Major Resolved Fixed James Nunez Maloo rhel8.3 Sun, 5 Jul 2020 18:03:43 +0000 Wed, 10 Feb 2021 00:10:42 +0000 Mon, 8 Feb 2021 22:04:46 +0000 Lustre 2.14.0 Lustre 2.14.0 0 8 <p>This failure occurred 8 times in the past two weeks. It's affecting the patch testing on master branch.</p> <p>The failure occurred 9 times in the past one week.</p> <p>Mike</p> <p>Could you please investigate?</p> <p>Thanks</p> <p>Peter</p> <p>The first failure I could find with this error message was <a href="https://testing.whamcloud.com/sub_tests/57f6774c-e2bb-11e9-9874-52540065bddc" class="external-link" target="_blank" rel="nofollow noopener">https://testing.whamcloud.com/sub_tests/57f6774c-e2bb-11e9-9874-52540065bddc</a></p> <p>I tend to think this is test script issue, the llog read from client sends RPC to server and <tt>ptlrpc_wait_queue()</tt> may ends up with <tt>-ESHUTDOWN</tt> on umount, so that is OK I'd say. Originally this test 160j was added in context of <a href="https://jira.whamcloud.com/browse/LU-11626" title="mdc: obd might go away while referenced by code in mdc_changelog" class="issue-link" data-issue-key="LU-11626"><del>LU-11626</del></a> to check there is no LBUG due to missed obd device so correctness of this test is not about 'changelog must be read after umount' but about the server shouldn't see LBUG during that. Therefore I think we should just consider that error as valid case during the test</p> <p>Thanks Mike. James will look into making that change.</p> <p>James Nunez (jnunez@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/41317" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/41317</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-13751" title="sanity test_160j: FAIL: read changelog failed" class="issue-link" data-issue-key="LU-13751"><del>LU-13751</del></a> tests: remove error on changelog read 160j<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: bf523dd41fd60ec0f585b898869567328394aeca</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/41317/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/41317/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-13751" title="sanity test_160j: FAIL: read changelog failed" class="issue-link" data-issue-key="LU-13751"><del>LU-13751</del></a> tests: remove read of changelog sanity 160j<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 388e8ed199b47337616beba573cb595343e71cca</p> <p>Landed for 2.14</p> Development Rank 1|i014f3: Rank (Obsolete) 9223372036854775807 Severity
