It may set lli-&gt;lli_layout_gen to LL_LAYOUT_GEN_EMPTY even though server doesn't support layout lock.</p> <p>Peter,</p> <p>I believe the issue exists for 2.1 server/2.4 client as well, if my bet on commit 9ac37e061 (<a href="https://jira.whamcloud.com/browse/LU-2689" title="Interop 2.1.4&lt;-&gt;2.4 failure on test suite runtests: Bad file descriptor" class="issue-link" data-issue-key="LU-2689"><del>LU-2689</del></a> interop: use stripe md in ll_update_inode()) is correct.</p> <p>Well, if that is the case then this would be a concern. How easy is it to hit this issue?</p> <p>I've got two reports on this today, both running sanity test suits on 2.4 clients against 2.2 server. I have a small patch fixing it and our QA is helping verifying it. Once verified, I will upload it for review.</p> <p>Patch uploaded to <a href="http://review.whamcloud.com/5866" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/5866</a></p> <p>With the patch applied, client no longer hang.</p> <p>close old tickets</p> Development Rank 1|hzvmdj: Rank (Obsolete) 7417 Severity
