Bug Minor Open Unresolved WC Triage Chris Horn Fri, 8 Feb 2019 20:04:15 +0000 Sat, 9 Feb 2019 00:31:06 +0000 Lustre 2.12.0 0 2 <p>at first glance when you run the command through lnetctl you're specifying the interface name, while in the module parameter case you're not. I suspect this causes the check in the code not to evaluate the second add as a duplicate.</p> <p>To confirm, you can you make the following change in the module parameters:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> options lnet ip2nets=<span class="code-quote">"gni99 10.129.*.*; gni4(ipogif0) 10.129.*.*"</span></pre> </div></div> <p>I think this might be clearer if you use:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> lnetctl net show </pre> </div></div> <p>to dump the configured networks instead of list_nids</p> Development Rank 1|i00bc7: Rank (Obsolete) 9223372036854775807 Severity
