They mainly appear on login nodes of our clusters. </p> <p>Here is an example of the error messages: <br/> Dec 17 10:24:28 ic2n988 kernel: <span class="error">&#91;512992.139174&#93;</span> LustreError: 11865:0 (mdc_locks.c:840:mdc_enqueue()) ldlm_cli_enqueue: -13 <br/> Dec 17 10:24:28 ic2n988 kernel: <span class="error">&#91;512992.139183&#93;</span> LustreError: 11865:0:(mdc_locks.c:840:mdc_enqueue()) Skipped 2 previous similar messages <br/> Dec 17 10:24:28 ic2n988 kernel: <span class="error">&#91;512992.139202&#93;</span> LustreError: 11865:0:(file.c:2716:ll_inode_revalidate_fini()) pfs2wor1: revalidate FID <span class="error">&#91;0x1d080001:0x86b7421d:0x0&#93;</span> error: rc = -13 <br/> Dec 17 10:24:28 ic2n988 kernel: <span class="error">&#91;512992.139208&#93;</span> LustreError: 11865:0:(file.c:2716:ll_inode_revalidate_fini()) Skipped 2 previous similar messages <br/> Dec 17 10:24:29 ic2n988 kernel: <span class="error">&#91;512993.347645&#93;</span> LustreError: 13000:0:(file.c:2716:ll_inode_revalidate_fini()) pfs2wor1: revalidate FID <span class="error">&#91;0x1d080001:0x86b7421d:0x0&#93;</span> error: rc = -13 </p> <p>The Lustre client in this case is at version 2.4.1 plus patch for <a href="https://jira.whamcloud.com/browse/LU-3645" title="Interop 2.1.5 &lt;--&gt; 2.4 Write operations during failover errors out instead of stalling" class="issue-link" data-issue-key="LU-3645"><del>LU-3645</del></a>. The servers are also at version 2.4.1. </p> <p>What do the messages mean, and how can we get rid of these error messages? </p> LU-4522

ldlm_cli_enqueue and ll_inode_revalidate_fini LustreError messages on 2.4.1 clients

Bug Minor Closed Fixed Andreas Dilger Oz Rentas Tue, 21 Jan 2014 19:05:21 +0000 Wed, 13 Sep 2017 16:51:20 +0000 Tue, 11 Mar 2014 16:22:28 +0000 Lustre 2.4.1 Lustre 2.6.0 0 3 <p>Could this be that login nodes have some users that are not known to MDS, similar to <a href="https://jira.whamcloud.com/browse/LU-4084" title="ll_inode_revalidate_fini()) failure -13" class="issue-link" data-issue-key="LU-4084"><del>LU-4084</del></a> for example?</p> <p>In Lustre 1.8 we used to return -EIDRM (Identifier Removed) so that it was clear this was an issue with missing users in the MDS user database, rather than some other kind of permission problem.</p> <p>We should also avoid printing these messages on the console, since they are just a distraction. I pushed <a href="http://review.whamcloud.com/8988" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8988</a> to quiet the client error messages for the common -EACCES error message.</p> <p>We can go ahead and close this one. Thanks.</p> <p>From the customer:<br/> The update from Andreas Dilger at 24/Jan/14 5:30 AM provided what we expected from this case: Improving the error message or get rid of unnecessary LustreError messages. Therefore, you can close this case.</p> <p>Patch 8828 was landed to master for 2.6.0. </p> Related LU-4705 Development Rank 1|hzwdbz: Rank (Obsolete) 12365 Severity
