rmdir allowed on nonempty striped directories

Bug Blocker Resolved Fixed Di Wang John Hammond dne2 Tue, 8 Apr 2014 15:20:24 +0000 Thu, 22 May 2014 13:27:55 +0000 Thu, 22 May 2014 13:27:55 +0000 Lustre 2.6.0 Lustre 2.6.0 0 4 <p>This probably will be fixed by patch series <a href="http://review.whamcloud.com/#/c/9699/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/9699/</a></p> <p>Just a quick note - Without any deeper investigation, this reminds me strongly of:<br/> <a href="https://jira.hpdd.intel.com/browse/LU-4471" class="external-link" target="_blank" rel="nofollow noopener">https://jira.hpdd.intel.com/browse/LU-4471</a></p> <p>If MDS unlinked an open striped directory, it needs to revalidate the layout of striped directory, so the client will be forced to revalidate the layout from the master MDT, instead of going to slave MDT directly. So it means we need LAYOUT lock for striped directory, and I will cook a patch.</p> <p><a href="http://review.whamcloud.com/#/c/10025/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/10025/</a> I chose an easy way to fix it now. Though I had a directory layout lock patch, probably land it to 2.7.</p> <p>All of fixes of readdir of stripe_dir has been merged to the fix of <a href="https://jira.whamcloud.com/browse/LU-4603" title="NFS reexport leads to problems of &quot;ls&quot;" class="issue-link" data-issue-key="LU-4603"><del>LU-4603</del></a><br/> <a href="http://review.whamcloud.com/#/c/9191/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/9191/</a> </p> <p>Let's mark this resolved when the fix has been merged to master. That way we don't forget about it somehow. And please don't resolve it as a duplicate of <a href="https://jira.whamcloud.com/browse/LU-4603" title="NFS reexport leads to problems of &quot;ls&quot;" class="issue-link" data-issue-key="LU-4603"><del>LU-4603</del></a> since that issue has a completely different description.</p> <p>Patch landed to Master. Please reopen if more work for this fix is needed.</p> Related LU-4603 Development Rank 1|hzwjjr: Rank (Obsolete) 13458 Severity
