Bug Minor Resolved Fixed WC Triage Maloo patch Mon, 30 Sep 2013 18:38:21 +0000 Tue, 14 Jan 2014 00:32:22 +0000 Tue, 19 Nov 2013 14:06:00 +0000 Lustre 2.5.0 Lustre 2.6.0 Lustre 2.5.1 0 9 <p>Looks like the five other cases of this failure are only being hit on SLES11 SP2. I suspect this is a test issue related to some difference in how bash interprets this stdout/stderr redirection.</p> <p>Also see this issue in SLES11 SP3 client:</p> <p><a href="https://maloo.whamcloud.com/test_sets/dc52a6a2-381a-11e3-844f-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/dc52a6a2-381a-11e3-844f-52540035b04c</a></p> <p>While I consider myself daily good at bash, I don't understand the construct:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> exec {FD}&lt;&gt;$file2 </pre> </div></div> <p>This seems to make SLES bash unhappy, but RHEL bash is ok. </p> <p>sanity.sh:test_236() uses</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>"{FD}&lt;&gt;$file2"</pre> </div></div> <p>to assign newly allocated file descriptor to FD, which is a feature added in bash-4.1-alpha.</p> <p>The below is how the feature is documented in bash changelog (<a href="http://tiswww.case.edu/php/chet/bash/CHANGES):" class="external-link" target="_blank" rel="nofollow noopener">http://tiswww.case.edu/php/chet/bash/CHANGES):</a><br/> p. If the optional left-hand-side of a redirection is of the form {var}, the<br/> shell assigns the file descriptor used to $var or uses $var as the file<br/> descriptor to move or close, depending on the redirection operator.</p> <p>SLES11SP3 uses bash-3.2 so the test_236 fails on SLES11SP3.</p> <p>This should be rewritten so that older bash will also work. </p> <p><a href="http://review.whamcloud.com/8181" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8181</a><br/> Please, take a look</p> <p>Landed for 2.6</p> <p>Lustre Build: <a href="http://build.whamcloud.com/job/lustre-b2_5/5/" class="external-link" target="_blank" rel="nofollow noopener">http://build.whamcloud.com/job/lustre-b2_5/5/</a><br/> Distro/Arch: RHEL6.4/x86_64(server), SLES11SP3/x86_64(client)</p> <p>The same failure occurred:<br/> <a href="https://maloo.whamcloud.com/test_sets/0c73c65e-763c-11e3-b3c0-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/0c73c65e-763c-11e3-b3c0-52540035b04c</a></p> <p>Here is the back-ported patch for Lustre b2_5 branch: <a href="http://review.whamcloud.com/8811" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8811</a></p> Development Rank 1|hzw4fr: Rank (Obsolete) 10826 Severity
