(see replay_request_or_update() ).</p> <p>In current implementation, this is done in target_update_lcd(), but multiple slot patch just changed this process, so target_update_lcd needs to be fixed as well.</p> LU-6840

This flag should not be set on exports for OSP.</p> <p>For cross-MDT operation, the updates (including update last_rcvd and reply_data) will be recorded on all of MDTs. So during the recovery, once the updates on the master MDT are missing, then these updates needs to be redo on the master MDT, which means these last_rcvd and reply_data file needs to be updated as well in this process, and those memory stuff (lcd etc) needs to be updated as well, which is normally through the trans stop callback. </p> <p>In current implementation, due to the speciality of the DNE recovery and recent changes of multiple slot, stop callback can not be called correctly, which is this patch trying to resolve.</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/15576/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/15576/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6840" title="update memory reply data in DNE update replay " class="issue-link" data-issue-key="LU-6840"><del>LU-6840</del></a> target: update reply data after update replay<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 9543df37cdfd35980c888440265d161e350d166d</p> <p>Landed for 2.8.</p> Blocker LU-6773 Related LU-5319 LU-6831 LU-6844 LU-7077 Development Rank 1|hzxi13: Rank (Obsolete) 9223372036854775807 Severity
