There are different conditions that need to be seperated.</p> <p>1) OST is deactivated on purpose. In this condition, no resend/retry from client. The client should be notified that the creation failure is caused by a previous configuration command. And it might be helpful to have some help message like "To fix the failure, try command \"lctl set_param osp.lustre-OST0001-osc-MDT0000.active=0\"". No every user/administrator has that much knowledge like Mitsuhiro.</p> <p>2) OST disconnects temporarily because of networks issue or restart. It seems better to cover this temporary failure and let the client application wait for the retry.</p> <p>3) MDT disconnects. The current retry works well.</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/37751/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/37751/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-13301" title="lfs setstripe to deactivated OST does not return" class="issue-link" data-issue-key="LU-13301"><del>LU-13301</del></a> lfs: return error when setstripe -o on inactive OSTs<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: f36f00811fddd8c1494cba080ebaaa44bbc284b2</p> <p>Landed for 2.14</p> Related Development Rank 1|i00ufj: Rank (Obsolete) 9223372036854775807 Severity
