Test failures associated with DNE index and stripe count randomization

Bug Minor Open Unresolved WC Triage Patrick Farrell Fri, 19 Apr 2019 17:21:47 +0000 Thu, 25 Jul 2019 09:35:21 +0000 0 6 <p>Has anyone tried applying the tests to an older master? I don't think that Cray is experiencing this volume of failures on our 2.11 or 2.12. Maybe there is some regression causing the problem that landing the tests only caught. Maybe the test improvements could be tried with git bisect and a rebased master?</p> <p>By the way, why are all of the recent related Bugs RESOLVED? None of them are resolved, right? We're just skipping tests that bring the bugs out. </p> <p>Because the failures associated with the <a href="https://jira.whamcloud.com/browse/LU-11636" title="t-f test_mkdir() does not support interop with non DNEII servers" class="issue-link" data-issue-key="LU-11636"><del>LU-11636</del></a> MDT randomization change are tracked here.  I opened this bug to track the underlying problem(s) and track resolving them.  Those other bugs serve(d) to track known test failures.  Any failures of those tests <b>currently</b> are <b>not</b> known failures and we don't want them getting tracked against those bugs (ie, if someone sees a failure in Maloo, we know it's not the one described by those bugs, and they should open a new bug).</p> <p> </p> <p>Note that <a href="https://jira.whamcloud.com/browse/LU-11560" title="recovery-small test 134 fails with ‘rm failed’" class="issue-link" data-issue-key="LU-11560">LU-11560</a> is still open because there was a pre-existing (rare) failure there.</p> <p> </p> <p>By the way, you noted elsewhere that Cray isn't seeing the same level of test issues with the MDT randomization change from <a href="https://jira.whamcloud.com/browse/LU-11636" title="t-f test_mkdir() does not support interop with non DNEII servers" class="issue-link" data-issue-key="LU-11636"><del>LU-11636</del></a>.  I know Cray uses a standard config for the test-framework testing, I believe it's 4 nodes?  Is that two MDS and two OSS?  How many MDTs are used, and how many on each node?  I'm trying to see how different the results of the randomization might be in that environment.</p> <p>@pfarrel, Cray uses two DNE configurations:</p> <ol> <li>Four-nodes with single mds: mds/mgs, oss, two clients.</li> <li>Ten-nodes: mgs, 3 mds, 2 oss, 4 clients.</li> </ol> Related LU-11560 LU-12175 LU-11636 LU-12171 LU-12176 Development Rank 1|i00f5b: Rank (Obsolete) 9223372036854775807 Severity
