sanity-lfsck test_6b: namespace lfsck completed unexpectedly

Bug Critical Resolved Fixed nasf Maloo Fri, 31 Oct 2014 13:29:04 +0000 Wed, 19 Nov 2014 23:18:13 +0000 Wed, 19 Nov 2014 23:18:13 +0000 Lustre 2.7.0 Lustre 2.7.0 0 4 <p>According to the log on MDS, when the namespace LFSCK started (resume from former run) for the last time, it seemed that the low layer iteration did not return more objects, as to the injected failure stub (OBD_FAIL_LFSCK_DELAY2) has not been triggered as expected, so there was no delay, so the LFSCK completed quickly. I have met such situation before. Although I did not catch the root reason, it should not related with the patch <a href="http://review.whamcloud.com/#/c/11848/14" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/11848/14</a>, because it has ever happened without this patch.</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java">00000004:00000080:0.0:1414753244.871791:0:9874:0:(mdt_handler.c:5682:mdt_iocontrol()) handling ioctl cmd 0xc00866e6 00100000:10000000:1.0:1414753245.981101:0:9876:0:(lfsck_engine.c:1620:lfsck_assistant_engine()) lustre-MDT0000-osd: lfsck_namespace LFSCK assistant thread start 00100000:10000000:1.0:1414753245.981150:0:9875:0:(lfsck_namespace.c:3966:lfsck_namespace_prep()) lustre-MDT0000-osd: namespace LFSCK prep done, start pos [732, [0x200000bd4:0xdf:0x0], 0xa6f862b9510000]: rc = 0 00100000:10000000:1.0:1414753245.981685:0:9875:0:(lfsck_namespace.c:4181:lfsck_namespace_post()) lustre-MDT0000-osd: namespace LFSCK post done: rc = 0 00100000:10000000:1.0:1414753245.981695:0:9876:0:(lfsck_engine.c:1691:lfsck_assistant_engine()) lustre-MDT0000-osd: lfsck_namespace LFSCK assistant thread post </pre> </div></div> <p>Here is another failure instance without the patch 11848:<br/> <a href="https://testing.hpdd.intel.com/test_sets/4ce9f344-5ca4-11e4-b9ce-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sets/4ce9f344-5ca4-11e4-b9ce-5254006e85c2</a></p> <p>Another failure instance with the patch 11848:<br/> <a href="https://testing.hpdd.intel.com/test_sets/5a28e144-626e-11e4-b9a7-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sets/5a28e144-626e-11e4-b9a7-5254006e85c2</a></p> <p>Inside the lfsck_prep(), the returned value from lfsck_open_dir() was not properly handled before returned back to the caller.
