lfs find can't work correctly

Bug Minor Resolved Fixed Emoly Liu Emoly Liu Thu, 20 Apr 2017 07:26:45 +0000 Tue, 9 May 2017 04:20:42 +0000 Tue, 9 May 2017 04:20:42 +0000 Lustre 2.10.0 0 3 <p>This issue is related to the PFL patch <a href="https://review.whamcloud.com/#/c/26391" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/#/c/26391</a></p> <p>I think it could be an old bug, cb_find_init() mistakenly used previous file's lum for the next dir, because the dir doesn't have default layout. Old code happen to zeroed the stripe count every time, that's probably why 'lfs find -c' works for old code. I think other options such as 'lfs find -S' would fail on old code too. Could you verify this?</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java">diff --git a/lustre/utils/liblustreapi.c b/lustre/utils/liblustreapi.c index 23691fb..42da570 100644 --- a/lustre/utils/liblustreapi.c +++ b/lustre/utils/liblustreapi.c @@ -3338,6 +3338,8 @@ <span class="code-keyword">static</span> <span class="code-object">int</span> cb_find_init(<span class="code-object">char</span> *path, DIR *parent, DIR **dirp, <span class="code-keyword">if</span> (ret != 0) <span class="code-keyword">return</span> ret; } + + param-&gt;fp_lmd-&gt;lmd_lmm.lmm_magic = 0; ret = get_lmd_info(path, parent, dir, param-&gt;fp_lmd, param-&gt;fp_lum_size); <span class="code-keyword">if</span> (ret == 0 &amp;&amp; param-&gt;fp_lmd-&gt;lmd_lmm.lmm_magic == 0 &amp;&amp; </pre> </div></div> <p>I think above patch can fix the problem.</p> <p>Niu, thanks for your patch!
