Add option to create new OSTs inactive

New Feature Minor Resolved Fixed Andreas Dilger Andrew Elwell LTS12 easy Thu, 28 Feb 2019 22:08:23 +0000 Mon, 4 Dec 2023 18:59:09 +0000 Fri, 3 Jan 2020 02:39:37 +0000 Lustre 2.14.0 0 5 <p>With the landing of <a href="https://jira.whamcloud.com/browse/LU-12025" title="Adding OST may cause EIO - delay activation of new OSTs on existing filesystem" class="issue-link" data-issue-key="LU-12025"><del>LU-12025</del></a> it should be relatively straight forward to add a mount option (maybe "<tt>nocreate</tt>" or "<tt>disabled</tt>" or "<tt>deactivated</tt>" or similar) that sets <tt>ofd-&gt;ofd_no_precreate</tt> immediately at mount time so that the MDS will not use it. This should have a test that verifies a newly-added OST is not used (even if requested specifically) when mounted with this option.</p> <p>Andreas Dilger (adilger@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/36716" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36716</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12036" title="Add option to create new OSTs inactive" class="issue-link" data-issue-key="LU-12036"><del>LU-12036</del></a> ofd: add "nocreate" mount option<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 6de22b05b9881436fd4ec1d724758a69ba8673b0</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/36716/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36716/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12036" title="Add option to create new OSTs inactive" class="issue-link" data-issue-key="LU-12036"><del>LU-12036</del></a> ofd: add "no_precreate" mount option<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 416e67222b769df490a8be034ef987a596dd8dff</p> <p>Landed for 2.14</p> <p>Minh Diep (mdiep@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/37133" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/37133</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12036" title="Add option to create new OSTs inactive" class="issue-link" data-issue-key="LU-12036"><del>LU-12036</del></a> ofd: add "no_precreate" mount option<br/> Project: fs/lustre-release<br/> Branch: b2_12<br/> Current Patch Set: 1<br/> Commit: ab889485b994814804059967a98f2da28590e956</p> Related LU-12025 LU-17300 LU-17334 Development Rank 1|i00cjr: Rank (Obsolete) 9223372036854775807
