Not much data available in the test logs, is this a possible clean-up issue? </p> <p>This test is exercising functionality that does not exist in older branches. The patch was landed to master in commit v2_13_53-145-g186b97e68a, and never ported to b2_12. It looks like it <b>has</b> an appropriate MDS version check, but it looks like the "<tt>btime_supported</tt>" check is broken in some way so it is still being run against unsupported servers (i.e. 2.12.9 or 2.10.8):<br/> <a href="https://testing.whamcloud.com/test_sets/7325910f-1ac5-4762-bfeb-1abe5069c8dc" class="external-link" target="_blank" rel="nofollow noopener">https://testing.whamcloud.com/test_sets/7325910f-1ac5-4762-bfeb-1abe5069c8dc</a><br/> <a href="https://testing.whamcloud.com/test_sets/f8522b34-7bc2-48ce-ab9a-1d624bb96203" class="external-link" target="_blank" rel="nofollow noopener">https://testing.whamcloud.com/test_sets/f8522b34-7bc2-48ce-ab9a-1d624bb96203</a><br/> <a href="https://testing.whamcloud.com/test_sets/37d33000-82b7-4db7-ab63-0f5545df344c" class="external-link" target="_blank" rel="nofollow noopener">https://testing.whamcloud.com/test_sets/37d33000-82b7-4db7-ab63-0f5545df344c</a><br/> <a href="https://testing.whamcloud.com/test_sets/c89556e1-3d0e-4819-8467-f321b8098dc4" class="external-link" target="_blank" rel="nofollow noopener">https://testing.whamcloud.com/test_sets/c89556e1-3d0e-4819-8467-f321b8098dc4</a><br/> <a href="https://testing.whamcloud.com/test_sets/01403241-7b5e-48fe-889e-502108f874e1" class="external-link" target="_blank" rel="nofollow noopener">https://testing.whamcloud.com/test_sets/01403241-7b5e-48fe-889e-502108f874e1</a><br/> <a href="https://testing.whamcloud.com/test_sets/1b89faae-8df3-4c23-8963-1957b0f8a6e6" class="external-link" target="_blank" rel="nofollow noopener">https://testing.whamcloud.com/test_sets/1b89faae-8df3-4c23-8963-1957b0f8a6e6</a></p> <p>It looks like the "<tt>btime_supported</tt>" function is only verifying that the client's "<tt>lfs find</tt>" command has the <tt>-btime</tt> option, and not really checking if it returns something useful, so I think that whole function should be removed and just stick with the MDS version check. I don't think the <em>client</em> version check is useful either at this point, since any client that is running this test will have this patch, so it can also be removed.</p> <p>Also note that <tt>test_56oc</tt> was "correctly" skipping old MDS versions because it was trying to run the <tt>btime_supported()</tt> function that was defined <b>after</b> <tt>test_56oc</tt>, so this would always return false and depend only on the version check. That bug-that-is-fixing-the-test will also be addressed by removing this check from <tt>test_56oc</tt>.</p> <p>"Andreas Dilger &lt;adilger@whamcloud.com&gt;" uploaded a new patch: <a href="https://review.whamcloud.com/c/fs/lustre-release/+/51580" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/c/fs/lustre-release/+/51580</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-15235" title="sanity test_56od: &#39;/usr/bin/lfs find /mnt/lustre/d56od.sanity -newerbb /mnt/lustre/f56od.sanity.ref ! -newerbb /mnt/lustre/f56od.sanity.negref -type d&#39; wrong: found 5, expected 4" class="issue-link" data-issue-key="LU-15235"><del>LU-15235</del></a> tests: skip sanity/56od in interop<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 8add332bda0c58d9908478b9263e8aea46edc135</p> <p>"Oleg Drokin &lt;green@whamcloud.com&gt;" merged in patch <a href="https://review.whamcloud.com/c/fs/lustre-release/+/51580/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/c/fs/lustre-release/+/51580/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-15235" title="sanity test_56od: &#39;/usr/bin/lfs find /mnt/lustre/d56od.sanity -newerbb /mnt/lustre/f56od.sanity.ref ! -newerbb /mnt/lustre/f56od.sanity.negref -type d&#39; wrong: found 5, expected 4" class="issue-link" data-issue-key="LU-15235"><del>LU-15235</del></a> tests: skip sanity/56od in interop<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: be8865ee16b97866d1ee9b9f644295dafa19461c</p> <p>Landed for 2.16</p> Related Development Rank 1|i02a07: Rank (Obsolete) 9223372036854775807 Severity
