So this tool is mainly used for old Lustre release or under the case that the customer does not wants to run namespace LFSCK that may take long time on very large system.</p> <p>Some enhancement can be considered: more integrated online tools that uses ll_decode_linkea and fid2path functionality, and can directly show the original position in the namespace; in further, it can move such orphan back to its original position.</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/20444/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/20444/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-8289" title="add ll_decode_linkea tool" class="issue-link" data-issue-key="LU-8289"><del>LU-8289</del></a> utils: add ll_decode_linkea tool<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 11a138cb9d005ef0180421bd17542071b63e18d9</p> <p>Landed for 2.9</p> Development Rank 1|hzyeu7: Rank (Obsolete) 9223372036854775807
