strange breakage in sanityn test 93

Bug Minor Resolved Fixed WC Triage Oleg Drokin Fri, 28 Jun 2019 17:51:24 +0000 Sat, 14 Dec 2019 13:57:07 +0000 Sat, 14 Dec 2019 13:57:07 +0000 Lustre 2.13.0 Lustre 2.12.3 Lustre 2.14.0 0 5 <p>The issue is something with this line:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre> do_facet $SINGLEMDS "lctl set_param -n \ 'lod.lustre-MDT*/qos_threshold_rr' $old_rr" </pre> </div></div> <p>Note that 17 is the default value of qos_threshold_rr.  So somehow $old_rr is its own command.</p> <p>If you compare to the previous set_param in this function:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre> do_facet $SINGLEMDS lctl set_param -n \ 'lod.lustre-MDT*/qos_threshold_rr' 100 </pre> </div></div> <p>Something that stands out in the problematic line is the wrapped double and then single quotes.</p> <p>Presumably that's the problem, confusing some version of bash.</p> <p>I did a quick patch.</p> <p>Ah, nevermind.</p> <p>It's this:<br/> local old_rr=$(do_facet $SINGLEMDS $LCTL get_param -n \<br/> lod.lustre-MDT*/qos_threshold_rr | sed -e 's/%//')</p> <p>If you've got more than one MDT, old_rr isn't one value, it's several with a newline in between them.</p> <p>Patrick Farrell (pfarrell@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/35366" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/35366</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12488" title="strange breakage in sanityn test 93" class="issue-link" data-issue-key="LU-12488"><del>LU-12488</del></a> tests: Fix sanityn 93 for dne configs<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 9c0890b5557830851ba42a7707877062160b2a69</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/35366/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/35366/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12488" title="strange breakage in sanityn test 93" class="issue-link" data-issue-key="LU-12488"><del>LU-12488</del></a> tests: Fix sanityn 93 for DNE configs<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 98e7614b9f422d45f5d1789eb550d1b7947522b1</p> <p>Landed for 2.14</p> Development Rank 1|i00ix3: Rank (Obsolete) 9223372036854775807 Severity
