Test failure on sanity-quota test_18: watchdog triggered

Bug Minor Resolved Fixed James Nunez James Nunez Thu, 9 May 2013 16:29:07 +0000 Wed, 10 Jul 2013 13:49:50 +0000 Wed, 10 Jul 2013 13:49:50 +0000 Lustre 2.5.0 0 2 <p>sanity-quota test_6 and test_18 check watchdog in same way, i.e. very similar code. Fixes will be similar.</p> <p>The proposed patch is at:<br/> <a href="http://review.whamcloud.com/#change,6310" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,6310</a></p> <p>The problem here is that test_18 is picking up lines from dmesg from any test. The awk command</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>local watchdog=$(awk '/sanity-quota test 18/ {start = 1;} /Service thread pid/ &amp;&amp; /was inactive/ { if (start) { print; } }' $TMP/lustre-log-${TESTNAME}.log) </pre> </div></div> <p>sets the start flag to 1 when it sees "sanity-quota test 18" in dmesg, but the flag is never turned off. So, if "sanity-quota test 18" is seen once in dmesg, we get a false positive if any other test generated a message with "Service thread pid" and "was inactive" in it. </p> <p>I chose to implement Oleg's suggested fix for <a href="https://jira.whamcloud.com/browse/LU-3195" title="Interop 2.3.0&lt;-&gt;2.3.63 sanity-quota test_6: " class="issue-link" data-issue-key="LU-3195"><del>LU-3195</del></a>, which is this same issue for test_6, which is to clear dmesg at the beginning of test_18. </p> <p>Patch landed to master.</p> Related LU-2283 LU-3195 Development Rank 1|hzvqjz: Rank (Obsolete) 8186 Severity
