However with the inherit depth, only new directories whose depth to ROOT is not larger than the inherit depth will inherit this default LMV to create.</p> LU-14792

DNE3: enable filesystem-wide default LMV

New Feature Major Resolved Fixed Lai Siyao Lai Siyao Fri, 25 Jun 2021 02:10:31 +0000 Mon, 4 Dec 2023 18:57:46 +0000 Sat, 31 Jul 2021 13:24:52 +0000 Lustre 2.15.0 0 4 <p>In theory, we could keep the directory depth in memory for each directory object when the path is walked from <tt>ROOT/</tt> during normal pathname lookups. That would allow inheriting the directory layout from ROOT with a limited max_inherit depth when creating directories that didn't previously inherit from ROOT. </p> <p>Ideally, we wouldn't need to explicitly copy the layout to each directory, since that makes life difficult if the root layout ever changes, but it may be too complex for the first version (eg. handling remote directories, etc). </p> <p>In the common case of <tt>max_inherit=-1</tt> there is never a need to explicitly copy the ROOT/ layout. </p> <p>Lai Siyao (lai.siyao@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/44090" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/44090</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-14792" title="DNE3: enable filesystem-wide default LMV" class="issue-link" data-issue-key="LU-14792"><del>LU-14792</del></a> llite: enable filesystem-wide default LMV<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 91ee6a144add71059aae154362fd7b34fda2166d</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/44090/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/44090/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-14792" title="DNE3: enable filesystem-wide default LMV" class="issue-link" data-issue-key="LU-14792"><del>LU-14792</del></a> llite: enable filesystem-wide default LMV<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: b9c4dc3c33fe87ecaa79a290190524ea21b7fa8a</p> <p>Landed for 2.15</p> Related LU-13417 LU-17300 LU-12434 LU-15200 LU-15736 LU-15314 Development Rank 1|i01xpz: Rank (Obsolete) 9223372036854775807 Severity
