Documentation needed for MR Routing

New Feature Blocker Resolved Fixed Amir Shehata Joseph Gmitter Tue, 11 Jun 2019 17:23:26 +0000 Fri, 24 Apr 2020 19:26:26 +0000 Thu, 7 Nov 2019 15:51:09 +0000 Lustre 2.13.0 Manual 0 4 <p>PDF version of the doc attached, which needs to be translated into a docbook patch.</p> <p>"The following changes are brought in" - you are speaking to what was added in 2.13?</p> <p>Also, we already have a Multi-Rail Routing section (16.5) in the ops manual, which was taken from <a href="https://wiki.whamcloud.com/display/LNet/Multi-Rail+%28MR%29+Routing" class="external-link" target="_blank" rel="nofollow noopener">https://wiki.whamcloud.com/display/LNet/Multi-Rail+%28MR%29+Routing</a>. Can you integrate that material with this material so that someone can make a patch to update the manual?</p> <p>That section shows how to configure Multi-Rail with the routing feature before the Multi-Rail Routing Feature landed in 2.13. Routing code has always monitored the state of the route, in order to avoid using unavailable ones. This section describes how you can configure multiple interfaces on the same gateway node but as different routes. This way we can use the existing route monitoring algorithm to guard against interfaces going down.</p> <p>With the Multi-Rail routing feature which landed in 2.13 the new algorithm uses the health feature to monitor the different interfaces of the gateway and always ensures that we use the healthiest interface. Therefore, the configuration trick described on this wiki page is no longer needed, however, can still work.</p> <p>Joseph Gmitter (jgmitter@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/36573" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36573</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LUDOC-441" title="Documentation needed for MR Routing" class="issue-link" data-issue-key="LUDOC-441"><del>LUDOC-441</del></a> lnet: Add Multi-Rail Routing Documentation<br/> Project: doc/manual<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: b16d0e5b90a17c183b878e96e6f0ed1c38ae8f55</p> <p>The patch above is an initial, direct translation from the wiki page noted above.</p> <p><a href="https://jira.whamcloud.com/secure/ViewProfile.jspa?name=ashehata" class="user-hover" rel="ashehata">ashehata</a> please be on the lookout for the review feedback (including my own) and update the patch accordingly.</p> <p>Joseph Gmitter (jgmitter@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/36573/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36573/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LUDOC-441" title="Documentation needed for MR Routing" class="issue-link" data-issue-key="LUDOC-441"><del>LUDOC-441</del></a> lnet: Add Multi-Rail Routing Documentation<br/> Project: doc/manual<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 1c600ce8d3a2dec1134376536470736e35a855cf</p> Gantt End to End LU-11297 Development Rank 1|i00i0v: Rank (Obsolete) 9223372036854775807
