Test failure on test suite sanity, subtest test_24w

After it was committed on 11 May, the sanity tests 24w,34</p> {c,d,g} <p>, started failing on i686 client. Here are the search results of the historical Maloo reports:</p> <p>test 24w: <a href="http://tinyurl.com/cf9uvj2" class="external-link" target="_blank" rel="nofollow noopener">http://tinyurl.com/cf9uvj2</a><br/> test 34c: <a href="http://tinyurl.com/clzdw2k" class="external-link" target="_blank" rel="nofollow noopener">http://tinyurl.com/clzdw2k</a></p> <p>Unfortunately, it was my proposal that caused this problem. I'm surprised that it only caused so few issues during testing.</p> <p>The patch is fairly straight forward - change libcfs_log_return() to return long long. Even with sign extension, the original value should be OK after casting the value down to the original type again.</p> <p>That must mean the same problem also exists for 32-bit clients on master. Are we no longer doing any 32-bit testing on master? I thought we would drop i686 <em>server</em> and RHEL5 <em>server</em> build/test, but I thought we would keep RHEL5/i686 <em>client</em> testing going to ensure we have at least some 32-bit test coverage.</p> <p>Hongchao</p> <p>Could you please look into this one?</p> <p>Thanks</p> <p>Peter</p> <p>Marking for a blocker on 2.1.2 as well.</p> <p>the patch is tracked at <a href="http://review.whamcloud.com/#change,3072" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,3072</a></p> <p>could someone check lustre builds with --disable-liblustre please ?</p> <p>status update:<br/> the tests against the patch has passed and is still under inspection(currently one +)</p> <p>Landed for 2.3</p> Duplicate LU-1437 Related LU-969 LU-4357 Development Rank 1|hzv62n: Rank (Obsolete) 4518 Severity
