Here's the signature :</p> <p>LustreError: 29856:0:(osd_handler.c:1967:osd_object_ref_del())<br/> ASSERTION(inode-&gt;i_nlink &gt; 0) failed<br/> Pid: 29856, comm: mdt_24</p> <p>As they provided a system dump, I have analysed it with crash and provided the trace in attachement (stack and content of inode structure).</p> LU-484

LASSERT(inode->i_nlink > 0) failed in osd_handler.c:osd_object_ref_del()

Thanks.</p> <p>Well, __mdd_ref_add() is noop if MNLINK_OBJ is set, while __mdd_ref_del(..., 1) definitely calls osd_object_ref_del().<br/> Is this possible to have MNLINK set at this stage?</p> <p>This is a newly created dir, the NMLINK_OBJ should not be set, of course, it's possible if there is bug. Even if the MNLINK_OBJ was set, the i_nlink should be 1, so it really confused me.</p> <p>Hi Niu,<br/> It was only reported to me that an IO benchmark was running. I have transmited your question to our on-site Support team.<br/> Patrick</p> <p>The calling trace is like this</p> <div class="code panel" style="border-width: 1px;"><div class="codeHeader panelHeader" style="border-bottom-width: 1px;"><b>namei.c</b></div><div class="codeContent panelContent"> <pre class="code-java">mdd_object_initialize()-&gt; __mdd_index_insert_only(...dotdot...)-&gt; osd_index_ea_insert()-&gt; osd_add_dot_dotdot-&gt; ldiskfs_add_dot_dotdot() </pre> </div></div> <p>and please see ldiskfs/ext4_add_dot_dotdot:</p> <div class="code panel" style="border-width: 1px;"><div class="codeHeader panelHeader" style="border-bottom-width: 1px;"><b>namei.c</b></div><div class="codeContent panelContent"> <pre class="code-java"> inode-&gt;i_op = &amp;ext4_dir_inode_operations; inode-&gt;i_fop = &amp;ext4_dir_operations; inode-&gt;i_size = EXT4_I(inode)-&gt;i_disksize = inode-&gt;i_sb-&gt;s_blocksize; dir_block = ext4_bread(handle, inode, 0, 1, &amp;err); <span class="code-keyword">if</span> (!dir_block) { clear_nlink(inode); ext4_mark_inode_dirty(handle, inode); iput (inode); <span class="code-keyword">goto</span> get_out; } </pre> </div></div> <p>As we can see, if ext4_bread() failed to create a block, clear_nlink(inode) will set inode-&gt;i_nlink to ZERO and I think that's the reason we got the assertion in __mdd_ref_del() called in the code block below</p> <div class="code panel" style="border-width: 1px;"><div class="codeHeader panelHeader" style="border-bottom-width: 1px;"><b>namei.c</b></div><div class="codeContent panelContent"> <pre class="code-java"> <span class="code-keyword">if</span> (S_ISDIR(ma-&gt;ma_attr.la_mode)) { <span class="code-comment">/* Add <span class="code-quote">"."</span> and <span class="code-quote">".."</span> <span class="code-keyword">for</span> newly created dir */</span> __mdd_ref_add(env, child, handle); rc = __mdd_index_insert_only(env, child, mdo2fid(child), dot, handle, BYPASS_CAPA); <span class="code-keyword">if</span> (rc == 0) rc = __mdd_index_insert_only(env, child, pfid, dotdot, handle, BYPASS_CAPA); <span class="code-keyword">if</span> (rc != 0) __mdd_ref_del(env, child, handle, 1); } </pre> </div></div> <p>Hi, Liang</p> <p>Thank you for pointing out this, I think you are right.
