It shouldn't run for longer than about 5 minutes per policy (independent of the storage speed) so that it doesn't consume an inordinate amount of testing time for each patch. There needs to be both file-per-process and shared-single-file IO from multiple clients to exercise the different policies properly, so sanityn.sh is probably a good place for it.</p> <p>Nikitas,<br/> any progress on getting some regression tests for NRS? Just some basic tests to run each policy for a few minutes under load would be great.</p> <p>As it stands, I tried enabling NRS with the ORR policy on my home server (2.4.1) while it was under load and it crashed almost instantly (bug to be filed separately), so I don't think that code is getting enough testing.</p> <p>Hi,</p> <p>Andreas, apologies for the long delay, but I have been on a long (hopefully temporary) 'break' from Lustre work during the last few months. I have spoken to our core Lustre team to see who will be handling this, and hopefully other NRS maintenance work, and we will update with this information as soon as we decide on a way forward; I hope that is an acceptable solution, please let me know if not.</p> <p>Sergey &lt;sergey_cheremencev@xyratex.com&gt; from our team has started working on addressing this ticket.</p> <p>Hi,</p> <p>I've added patch <a href="http://review.whamcloud.com/#/c/9286/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/9286/</a>.<br/> Think will be a lot of comments...</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/9286/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/9286/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-3266" title="Regression tests for NRS policies" class="issue-link" data-issue-key="LU-3266"><del>LU-3266</del></a> test: regression tests for nrs policies<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 38b68e47e5e240fd8d394a944737ecdbcf2fb70f</p> <p>Landed for 2.8</p> Related LU-6668 LU-3558 Development Rank 1|hzvq1j: Rank (Obsolete) 8086
