Can you give me link?</p> <p>Thanks,<br/> -Ulka</p> <p>Hi Ulka</p> <p>It is an joke reference to a comment at a past LUG. He means the Lustre manual.</p> <p>Peter</p> <p>Thanks for clarification <img class="emoticon" src="https://jira.whamcloud.com/images/icons/emoticons/smile.png" height="16" width="16" align="absmiddle" alt="" border="0"/></p> <p>Hi,<br/> I have analyzed this issue; here is prospective solution -<br/> 1. lctl dl call reads /proc/fs/lustre/devices file<br/> 2. This proc code looks for obd-&gt;obd_inactive flag and accordingly sets the status.<br/> 3. Whenever we deactivate OST device it is ultimately received by osp <br/> 4. At OSP osp_import_event function handles the activation or deactivation of OST<br/> 5. However we are not notifying obd to set upcall for state change.<br/> 6 We need to register osp_notify function and call obd_notify.</p> <p>Thanks,<br/> -Ulka</p> <p>Yang Sheng (yang.sheng@intel.com) uploaded a new patch: <a href="http://review.whamcloud.com/19402" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/19402</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6601" title="deactivated OSTs do not appear to be inactive according to &#39;lctl dl&#39;" class="issue-link" data-issue-key="LU-6601"><del>LU-6601</del></a> osp: update obd status while osp status changed<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 34c353ffb385f50d5088b7cc5b11ccad8eb2ff80</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/19402/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/19402/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6601" title="deactivated OSTs do not appear to be inactive according to &#39;lctl dl&#39;" class="issue-link" data-issue-key="LU-6601"><del>LU-6601</del></a> osp: update obd status while osp status changed<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: ba2ac3502026fcf7399ac102d24bbb7f3d7a8c87</p> <p>Yang Sheng (yang.sheng@intel.com) uploaded a new patch: <a href="http://review.whamcloud.com/19637" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/19637</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6601" title="deactivated OSTs do not appear to be inactive according to &#39;lctl dl&#39;" class="issue-link" data-issue-key="LU-6601"><del>LU-6601</del></a> tests: test case validate OSP status op<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 2c793405e86d21dadce17e65d348c45ee226e0d3</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/19637/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/19637/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6601" title="deactivated OSTs do not appear to be inactive according to &#39;lctl dl&#39;" class="issue-link" data-issue-key="LU-6601"><del>LU-6601</del></a> tests: test case validate OSP status op<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: f5f62250886e8c68e7f0dee9c2842c3075a69654</p> <p>Patch landed, So close this ticket.</p> Duplicate LU-7731 Related LU-7668 Development Rank 1|hzxdaf: Rank (Obsolete) 9223372036854775807 Severity
