Remove these components, replacing them with a new subsystem that implements transactional access to non-local OSDs to ensure a rigorous separation of client/server and server/server protocols which avoids existing recovery race conditions.</p> LU-1303 LOD/OSP Implementation New Feature Critical Resolved Fixed Alex Zhuravlev Mikhail Pershin Wed, 11 Apr 2012 01:58:08 +0000 Mon, 29 May 2017 04:11:19 +0000 Mon, 29 May 2017 04:11:19 +0000 Lustre 2.4.0 0 2 <p>There are a number of generated compile warnings in the code that need to be fixed due to LOD/OSP workarounds that need to be removed, such as:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java">#<span class="code-keyword">if</span> LUSTRE_VERSION_CODE &lt; OBD_OCD_VERSION(2, 3, 50, 0) <span class="code-keyword">if</span> (rc == 0 &amp;&amp; ma-&gt;ma_valid &amp; MA_COOKIE &amp;&amp; ma-&gt;ma_valid &amp; MA_LOV &amp;&amp; ma-&gt;ma_valid &amp; MA_FLAGS &amp;&amp; ma-&gt;ma_attr_flags &amp; MDS_UNLINK_DESTROY) /* Since echo client is incapable of destorying ost object, * it will destory the object here. */ rc = mdd_lovobj_unlink(env, mdd, mdd_cobj, la, ma, 1); #<span class="code-keyword">else</span> #warning <span class="code-quote">"please remove <span class="code-keyword">this</span> after 2.4 (LOD/OSP)."</span> #endif </pre> </div></div> <p>I've submitted <a href="http://review.whamcloud.com/3741" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/3741</a> to bump the version check to 2.3.55, to give the LOD/OSP patches a chance to land, but they should be removed as the LOD/OSP code is landed.</p> LU-2045 LU-2050 LU-2051 Development Epic/Theme Rank 1|hzurtz: Rank (Obsolete) 2171
