Bug Minor Open Unresolved WC Triage Chris Horn Fri, 8 Feb 2019 20:24:54 +0000 Tue, 22 Sep 2020 21:06:35 +0000 0 3 <p>This might be specific to gni gateways, as I can't seem to add a route even with the basic syntax:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>nid00127:/sys/kernel/debug/lnet # lnetctl route add --net o2ib40 --gateway 485@gni4 add: - route: errno: -8 descr: "Success" nid00127:/sys/kernel/debug/lnet # </pre> </div></div> <p>I'm guessing there's an assumption in the code that LNet endpoints all take the form &lt;ipv4_address&gt;@&lt;netname&gt;</p> <p>Yeah, looks like gni specifically not supported here:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre> /* expression support is for o2iblnd and socklnd only */ if (net_type != O2IBLND &amp;&amp; net_type != SOCKLND) return LUSTRE_CFG_RC_SKIP; </pre> </div></div> <p>yes, I believe at the time we decided to add command which we could test. Shouldn't be too difficult to add GNI support though. But you're right, we should probably not say "success" in this case and reflect the -8 return code.</p> <p>Another variant of the command with the misleading output:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre># lnetctl route add --net o2ib --gateway 192.168.2.24@tcp,192.168.2.25@tcp add: - route: errno: -8 descr: "Success" # </pre> </div></div> <p>Do you plan to add gni support? I have the same error when trying to add route from gni network to o2ib1 .</p> <p><a href="https://jira.whamcloud.com/secure/ViewProfile.jspa?name=alex.ku" class="user-hover" rel="alex.ku">alex.ku</a> Support for gni was added to various lnetctl commands under <a href="https://jira.whamcloud.com/browse/LU-12410" title="Refactor lnetctl peer nid handling to utilize nidstrings library" class="issue-link" data-issue-key="LU-12410"><del>LU-12410</del></a></p> Development Rank 1|i00bcf: Rank (Obsolete) 9223372036854775807 Severity
