"lfs find" should find the files that match all the specified component options

Bug Critical Resolved Fixed Niu Yawei Emoly Liu pfl Thu, 20 Apr 2017 09:16:45 +0000 Sat, 3 Jun 2017 04:20:34 +0000 Sat, 3 Jun 2017 04:20:34 +0000 Lustre 2.10.0 Lustre 2.10.0 0 6 <p>Except what you asked for is component start &lt; 100MB and component end &gt; 5Mb, which matches the first component. </p> <p>Right, <del>100M means at most 100M, and <ins>5M means at least 5M, I was also confused by these '</ins>' and '</del>' before and made it reversely in 'lfs getstripe' options.</p> <p>Regardless this improper example, there is a real problem found by Emoly, current implementation is that file will be matched if the criteria are matched by any components, for exmaple: if 1st component matches --component-start option, and 2nd component matches --component-end option, the file will be matched at the end. I think it make sense to change it as any single component matches all criteria.</p> <p>Niu Yawei (yawei.niu@intel.com) uploaded a new patch: <a href="https://review.whamcloud.com/26766" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/26766</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-9371" title="&quot;lfs find&quot; should find the files that match all the specified component options" class="issue-link" data-issue-key="LU-9371"><del>LU-9371</del></a> tools: handle component options properly<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: cdced3718893e2ae19d2ba6aa2c864e152a4f1be</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="https://review.whamcloud.com/26766/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/26766/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-9371" title="&quot;lfs find&quot; should find the files that match all the specified component options" class="issue-link" data-issue-key="LU-9371"><del>LU-9371</del></a> tools: handle component options properly<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 8e02647def0d806023cb3bb4b91c5b1e38ee2872</p> <p>Landed for 2.10</p> Development Rank 1|hzzaon: Rank (Obsolete) 9223372036854775807 Severity
