This caused the MDT to not be able to establish a connection and reports in the log as below.</p> <p>Note the <tt>0@&lt;0:0&gt;</tt> at the end that, I am guessing, should be the servicenode failover args and is reporting "<tt>0:0</tt>" instead. If it had reported the correct args, this would have been a much easier problem to figure out.</p> <p>Also in the mds log:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>class_config_llog_handler()) MGC192.168.20.121@o2ib: cfg command failed: rc = -2 cmd=cf003 0:lustrefs-OST0010-osc-MDT0000 1:lustrefs-OST0010_UUID 2:0@&lt;0:0&gt; </pre> </div></div> LU-8404

When service node nid is incorrect, MDT log message missing bad nid

Bug Minor Resolved Duplicate Hongchao Zhang Gary Hagensen Fri, 15 Jul 2016 05:32:06 +0000 Thu, 18 Aug 2016 21:32:32 +0000 Thu, 18 Aug 2016 21:32:31 +0000 Lustre 2.7.0 0 6 <p>Gary, can you please provide more details about how the NID was incorrect, so that this can be debugged/fixed properly and there can be a test case added for this. As it is, I have no idea how to reproduce this problem.</p> <p>The bad servicenode argument I used was the node's management interface @ tcp0 . So it was a valid IP, but not a valid NID as it is not on an LNET. The LNET interface was the IB interface. So I assume to reproduce all you would need is a system (or VMs) with 2 interfaces on the HA pair, one for management, one for LNET and define the service nodes to be on the non-lnet interface.</p> <p>the patch <a href="http://review.whamcloud.com/19933/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/19933/</a> from <a href="https://jira.whamcloud.com/browse/LU-8091" title="server_lsi2mti() should return error when fail to get nid" class="issue-link" data-issue-key="LU-8091"><del>LU-8091</del></a> can fix the problem.</p> <p>So this is confirmed as a duplicate of <a href="https://jira.whamcloud.com/browse/LU-8091" title="server_lsi2mti() should return error when fail to get nid" class="issue-link" data-issue-key="LU-8091"><del>LU-8091</del></a></p> Related Development Rank 1|hzyhk7: Rank (Obsolete) 9223372036854775807 Severity
