And this test never failed in maloo test.</p> <p>If there isn't enough logging enabled for this test you could push a patch on master that modifies the test, in case it is hit again in the future? Maybe including your extra CDEBUG changes?</p> <p>The latest patch worked and dumped when no permission file was created.</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>[root@ai400x2-1-vm1 ~]# lctl debug_file /scratch/log/lustre-log.1659427201.8549 | grep '##' 00000004:00020000:19.0:1659427201.471371:0:8549:0:(mdt_handler.c:877:mdt_pack_attr2body()) ##### [0x200000483:0xfd91:0x0] with mode 32768 uid 8888 gid 100 valid 1100000080002f8f [root@ec01 ~]# lfs fid2path /exafs "[0x200000483:0xfd91:0x0]" /exafs/home/sihara/mdtest.out/test-dir.0-0/mdtest_tree.162.0/file.mdtest.162.13744 [root@ec01 ~]# ls -l /exafs/home/sihara/mdtest.out/test-dir.0-0/mdtest_tree.162.0/file.mdtest.162.13744 ---------- 1 sihara users 0 Aug 2 17:00 /exafs/home/sihara/mdtest.out/test-dir.0-0/mdtest_tree.162.0/file.mdtest.162.13744 </pre> </div></div> <p>"Andreas Dilger &lt;adilger@whamcloud.com&gt;" uploaded a new patch: <a href="https://review.whamcloud.com/48233" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/48233</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-16056" title="rarely directories got created with the wrong permission" class="issue-link" data-issue-key="LU-16056"><del>LU-16056</del></a> libcfs: restore umask handling in kernel threads<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 06fe5984b7ebfe0153155546995576ea35f7ef21</p> <p>"Oleg Drokin &lt;green@whamcloud.com&gt;" merged in patch <a href="https://review.whamcloud.com/48233/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/48233/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-16056" title="rarely directories got created with the wrong permission" class="issue-link" data-issue-key="LU-16056"><del>LU-16056</del></a> libcfs: restore umask handling in kernel threads<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: c92bdd97d99cc755a187987f3d5963adeb3ea475</p> <p>Landed for 2.16</p> <p>"Jian Yu &lt;yujian@whamcloud.com&gt;" uploaded a new patch: <a href="https://review.whamcloud.com/48414" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/48414</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-16056" title="rarely directories got created with the wrong permission" class="issue-link" data-issue-key="LU-16056"><del>LU-16056</del></a> libcfs: restore umask handling in kernel threads<br/> Project: fs/lustre-release<br/> Branch: b2_15<br/> Current Patch Set: 1<br/> Commit: ac44a6c05afd67d9006c93132c354aef994c4383</p> Related Development Rank 1|i02vo7: Rank (Obsolete) 9223372036854775807 Severity
