That returns success (0) if the directory grew larger than the limit, which I thought the patch was trying to fix.</p> <p>There are also a few other places in the test that could be fixed. "while [ ! $I -gt $MAX ]" should instead be "while [ $I -lt $MAX ]", </p> <p>Emoly</p> <p>Could you please take care of this issue?</p> <p>Thanks</p> <p>Peter</p> <p>Not sure if this is significant or relevant, but have been running into this a lot in b2_5 test runs lately. Blocking what I think are good mods from landing. more examples:</p> <p><a href="https://maloo.whamcloud.com/test_sets/03d5618e-a51b-11e3-9fee-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/03d5618e-a51b-11e3-9fee-52540035b04c</a><br/> <a href="https://maloo.whamcloud.com/test_sets/dde0d8ba-a514-11e3-9e53-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/dde0d8ba-a514-11e3-9e53-52540035b04c</a></p> <p>I found that the test failed on Lustre b2_5 branch with MDSCOUNT=4, but passed with MDSCOUNT=2.</p> <p>MDSCOUNT=4:<br/> <a href="https://maloo.whamcloud.com/test_sets/10b85614-a6b4-11e3-b6b0-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/10b85614-a6b4-11e3-b6b0-52540035b04c</a></p> <p>MDSCOUNT=2:<br/> <a href="https://maloo.whamcloud.com/sub_tests/d9ac4fda-a6b4-11e3-9d0d-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/sub_tests/d9ac4fda-a6b4-11e3-9d0d-52540035b04c</a></p> <p>Another instance with Lustre b2_5 and 4 MDTs: <a href="https://maloo.whamcloud.com/test_sessions/8045b1ee-b9ff-11e3-805d-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sessions/8045b1ee-b9ff-11e3-805d-52540035b04c</a></p> <p>another in b2_5:<br/> <a href="https://maloo.whamcloud.com/test_sets/667cdba2-c044-11e3-8c28-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/667cdba2-c044-11e3-8c28-52540035b04c</a></p> <p>Another failure with b2_5:<br/> <a href="https://maloo.whamcloud.com/test_sets/e78c4e40-c048-11e3-8176-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/e78c4e40-c048-11e3-8176-52540035b04c</a></p> <p>Hit this again with b2_5 in review-dne-part-1<br/> <a href="https://maloo.whamcloud.com/test_sets/bb581f36-abc4-11e3-a696-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/bb581f36-abc4-11e3-a696-52540035b04c</a></p> <p>another in b2_5<br/> <a href="https://maloo.whamcloud.com/test_sessions/aa2bf6a6-c776-11e3-9a0e-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sessions/aa2bf6a6-c776-11e3-9a0e-52540035b04c</a></p> <p>Another b2_5 in review-dne-part-1 at <a href="https://maloo.whamcloud.com/test_sets/3f63c60c-c765-11e3-9ec5-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/3f63c60c-c765-11e3-9ec5-52540035b04c</a></p> <p>Another b2_5 failure in review-dne-part-1 at <a href="https://maloo.whamcloud.com/test_sets/84240626-b9ff-11e3-805d-52540035b04c" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/84240626-b9ff-11e3-805d-52540035b04c</a></p> <p>Backport the patch <a href="http://review.whamcloud.com/8137" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8137</a> to b2_5 <a href="http://review.whamcloud.com/10043" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/10043</a> to fix this problem.</p> <p>Patches have landed to Master and b2_5.</p> Related LU-2479 Development Rank 1|hzwffr: Rank (Obsolete) 12728 Severity
