https://jira.whamcloud.com This file is an XML representation of an issue en-us 9.4.14 940014 05-12-2023 https://jira.whamcloud.com/browse/LU-395 Lustre <p>obd_zombie_barrier() is supposed to make sure there are no exports remains and we can proceed with obd cleanup. In fact it makes sure only there are no exports in zombie list head, but export can be still not destroyed. This can lead to issues seen in ORI-125 and ORI-211, because lu_target is freed before all exports are gone. </p> <p>The solution could be fix for zombie barrier to make it really barrier which waits for all exports are destroyed.</p> LU-395

obd-&gt;obd_name, obd-&gt;obd_uuid.uuid); class_decref(obd, <span class="code-quote">"attach"</span>, obd); - - <span class="code-comment">/* not strictly necessary, but cleans up eagerly */</span> - obd_zombie_impexp_cull(); - RETURN(0); } </pre> </div></div> <p>I met this hang too. And after reviewing the code, I think Jinshan's patch should work: the backtrace above shows sys_umount -&gt; class_detach -&gt; obd_zombie_impexp_cull -&gt; filter_cleanup -&gt; obd_zombie_barrier, but the zombies_count will only be decreased after obd_zombie_impexp_cull, so this process is waiting for itself, this is a deadlock. I think it's okay to let zombie thread to call obd_zombie_impexp_cull, and this should also be the reason why a separate zombie thread is created.</p> <p>running mmp tests on the latest master build#173 rhel5/x86_64, and also review build#956, tests hang from the beginning. Bobi thought this is the same issue here. The failure can be reproduced every time.</p> <p>Integrated in <span class="image-wrap" style=""><img src="http://newbuild.whamcloud.com/images/16x16/blue.png" style="border: 0px solid black"
