Frequent Client Evictions

Bug Blocker Resolved Fixed Liang Zhen Dan Ferber Wed, 10 Nov 2010 06:36:06 +0000 Tue, 28 Jun 2011 15:01:37 +0000 Tue, 5 Apr 2011 06:00:09 +0000 Lustre 1.8.6 Lustre 2.1.0 0 2 <p>Liang, would you take a look at the current status and let Chris know what questions you have, in order to suggest the next step for whoever we assign to work on this bug. Thanks. </p> <p>Chris, I just wonder whether things are getting better with those two patches on BZ 23352, if there is still issue, it would be helpful if you can give us a full description.</p> <p>Thanks<br/> Liang</p> <p>We have the first patch, and it did help with that one issue.</p> <p>The "updated patch to fix at_min issue" has not, unfortunately, reached production yet. I have been pushing to get that installed, but I have not yet convinced them to perform a special install of lustre. I am currently waiting for the next major OS upgrade to happen, which will include that patch.</p> <p>It is possible that the first client cluster will get that second patch in late November.</p> <p>Status: Waiting to see what we find when the updated patch to fix at_min issue is able to be tested in the LLNL environment. </p> <p>Patch to fix at_min made it on to one set of servers. It seems to have completely worked around the timeouts and evictions we were seeing. The sysamdins are going to roll it out onto all servers.</p> <p>I am somewhat suspicious that <a href="https://jira.whamcloud.com/browse/LU-25" title="Blocking network request in ldlm shrinker" class="issue-link" data-issue-key="LU-25"><del>LU-25</del></a> is behind some of the unexpectedly long delays in the client's reply reaching the server.</p> <p>The at_min has been a huge help. I am fairly certain that <a href="https://jira.whamcloud.com/browse/LU-25" title="Blocking network request in ldlm shrinker" class="issue-link" data-issue-key="LU-25"><del>LU-25</del></a> is the really the root issue. But at_min clearly is not honored without this patch and needs to be fixed. The fix was landed on 1.8.6, and just needs landing on master.</p> <p>I've pushed it for landing:</p> <p> <a href="http://review.whamcloud.com/306" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/306</a></p> <p>Integrated in <span class="image-wrap" style=""><img src="http://build.whamcloud.com/images/16x16/blue.png" style="border: 0px solid black" /></span> <a href="http://build.whamcloud.com/job/reviews-centos5/408/" class="external-link" target="_blank" rel="nofollow noopener">reviews-centos5 #408</a><br/> <a href="https://jira.whamcloud.com/browse/LU-13" title="Frequent Client Evictions" class="issue-link" data-issue-key="LU-13"><del>LU-13</del></a> updated patch to fix at_min issue</p> <p>Christopher J.
