And then subsequent precreate will fail because the last_id known on MDT is less than that on OST. Instead, upon each failure, it should restart as a reconnect and cleanup orphans first, and then continue subsequent precreate. </p> LU-15009

precreate should cleanup orphans upon error

Bug Minor Resolved Fixed Lai Siyao Lai Siyao Thu, 16 Sep 2021 02:54:12 +0000 Thu, 27 Oct 2022 03:17:55 +0000 Thu, 23 Dec 2021 14:33:29 +0000 Lustre 2.12.9 Lustre 2.15.0 0 6 <p>In this case, the MDT should handle this by skipping OST objects below the <tt>LAST_ID</tt> value, rather than deleting OST objects back to the MDT <tt>last_id</tt> value. That would leave these objects available for recovery via LFSCK, if the problem was on the MDT (e.g. restored from backup), rather than deleting them.</p> <p>The description is updated, the issue is objects are created on OST, but MDT get error, IMO this is no different from a reconnect, and can be handled the same.</p> <p>"Lai Siyao &lt;lai.siyao@whamcloud.com&gt;" uploaded a new patch: <a href="https://review.whamcloud.com/44984" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/44984</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-15009" title="precreate should cleanup orphans upon error" class="issue-link" data-issue-key="LU-15009"><del>LU-15009</del></a> ofd: continue precreate if LAST_ID is less on MDT<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: bb30ada9d8f086bc3c2f97450df0fbb68d35f746</p> <p>"Oleg Drokin &lt;green@whamcloud.com&gt;" merged in patch <a href="https://review.whamcloud.com/44984/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/44984/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-15009" title="precreate should cleanup orphans upon error" class="issue-link" data-issue-key="LU-15009"><del>LU-15009</del></a> ofd: continue precreate if LAST_ID is less on MDT<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 1711e26ae861c28829870c2433caf7ee232909cf</p> <p>Landed for 2.15</p> <p>"Andreas Dilger &lt;adilger@whamcloud.com&gt;" uploaded a new patch: <a href="https://review.whamcloud.com/45930" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/45930</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-15009" title="precreate should cleanup orphans upon error" class="issue-link" data-issue-key="LU-15009"><del>LU-15009</del></a> ofd: continue precreate if LAST_ID is less on MDT<br/> Project: fs/lustre-release<br/> Branch: b2_12<br/> Current Patch Set: 1<br/> Commit: ac5034013c97f0e458252b7a337d3f184bd065ba</p> <p>"Oleg Drokin &lt;green@whamcloud.com&gt;" merged in patch <a href="https://review.whamcloud.com/45930/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/45930/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-15009" title="precreate should cleanup orphans upon error" class="issue-link" data-issue-key="LU-15009"><del>LU-15009</del></a> ofd: continue precreate if LAST_ID is less on MDT<br/> Project: fs/lustre-release<br/> Branch: b2_12<br/> Current Patch Set: <br/> Commit: 62d4e1d5f1be33abd3ee9f58cc09d471e22ee7ad</p> Related LU-5648 Development Rank 1|i024ev: Rank (Obsolete) 9223372036854775807 Severity
