The difficult part here is to return mdt body in callback instead of LVB which is updated inside LDLM code automatically.</p> LU-10664 DoM: make DoM lock enqueue non-blocking Technical task LU-10176 Minor Resolved Fixed Mikhail Pershin Mikhail Pershin Wed, 14 Feb 2018 14:55:55 +0000 Tue, 23 Feb 2021 00:22:22 +0000 Wed, 17 Feb 2021 20:56:53 +0000 Lustre 2.14.0 0 7 <p>Mike Pershin (mpershin@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/36903" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36903</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-10664" title="DoM: make DoM lock enqueue non-blocking" class="issue-link" data-issue-key="LU-10664"><del>LU-10664</del></a> dom: non-blocking enqueue for DOM locks<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 2<br/> Commit: ee5d22173a24ec30d59d2e03a46f0c65928e5315</p> <p>Mike Pershin (mpershin@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/37044" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/37044</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-10664" title="DoM: make DoM lock enqueue non-blocking" class="issue-link" data-issue-key="LU-10664"><del>LU-10664</del></a> tests: fix MPI tests in dom-performance.sh<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 87008972a64919b7fa13955b93b3f2dfd42ac386</p> <p>Hi Mike! I'm curious, have you made some progress on your patch "non-blocking enqueue for DOM locks" above? Do you still plan to work on it? We'll be happy to test it when it's ready, let me know. Thanks!</p> <p>Stephane, patch is ready, it is not just at high priority to inspect and land, so there is not much activity. Meanwhile you can take it and test, that would be very helpful, especially for cases with single file shared by many clients/processes</p> <p>I see, that sounds good, thanks! I will see what we can do to test that patch.</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/37044/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/37044/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-10664" title="DoM: make DoM lock enqueue non-blocking" class="issue-link" data-issue-key="LU-10664"><del>LU-10664</del></a> tests: fix MPI tests in dom-performance.sh<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: b6443b3799622f3e281b087f6cf0c86432887846</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/36903/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36903/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-10664" title="DoM: make DoM lock enqueue non-blocking" class="issue-link" data-issue-key="LU-10664"><del>LU-10664</del></a> dom: non-blocking enqueue for DOM locks<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 3c75d2522786a2a86db450a44da4e764d5ea8f30</p> <p>Landed for 2.14</p> Related LU-12935 Development Rank 1|hzzstj: Rank (Obsolete) 9223372036854775807
