Bug Major Resolved Fixed Nathaniel Clark Aleksey Senin Mon, 8 Sep 2014 22:30:26 +0000 Fri, 9 Oct 2015 20:50:55 +0000 Wed, 29 Jul 2015 15:55:19 +0000 Lustre 2.6.0 Lustre 2.8.0 0 11 <p>James,<br/> Can you provide more details on this issue?<br/> Thank you!</p> <p>I opened earlier another discussion on HPDD forum, so all details are there. It is probably better to union these two discussion.</p> <p>Here is the description of existing case.</p> <p>After installing Mellanox MOFED, I configured Luster in the following way<br/> ./configure --disable-server --with-o2ib=/usr/src/mlnx-ofed-kernel-2.3<br/> and was able to compile kernel modules.<br/> But the version of function symbols that were compiled in ko2iblnd<br/> module belongs to original kernel modules and not to the OFED<br/> modules. As results compiled module refuse to load.</p> <p>For example ib_destroy_cq function</p> <p>modprobe --dump-modversions<br/> /lib/modules/3.13.0-32-generic/extra/klnds/o2iblnd/ko2iblnd.ko |grep<br/> ib_destroy_cq<br/> 0xad52ad2c ib_destroy_cq</p> <p>And this is the address from the MOFED Module.symvers file<br/> root at kickseed:/usr/src/lustre-release# grep ib_destroy_cq Module.symvers<br/> 0x9a1f091e __crc_ib_destroy_cq<br/> /lib/modules/3.13.0-32-generic/updates/dkms/ib_core (unknown)</p> <p>It looks like an issue in Lustre.</p> <p>Setup</p> <p>Ubuntu-14.04<br/> kernel-3.13.0.32-generic<br/> MOFED-2.3</p> <p>Meanwhile, until the issue is fixed I've created my own fix in GitHub repository<br/> <a href="https://github.com/ahlabenadam/lustre_fix.git" class="external-link" target="_blank" rel="nofollow noopener">https://github.com/ahlabenadam/lustre_fix.git</a></p> <p>Vladimir Saveliev (vladimir_saveliev@xyratex.com) uploaded a new patch: <a href="http://review.whamcloud.com/12980" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/12980</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-5597" title="Kernel Module.symvers take precendene instead of MOFED provided" class="issue-link" data-issue-key="LU-5597"><del>LU-5597</del></a> mdd: initialize mdd's obd-&gt;obd_vars<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: b0859473660bdcc132e60c1f3a561ddb1772a352</p> <p>I mistakenly submitted <a href="http://review.whamcloud.com/12980" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/12980</a> with <a href="https://jira.whamcloud.com/browse/LU-5597" title="Kernel Module.symvers take precendene instead of MOFED provided" class="issue-link" data-issue-key="LU-5597"><del>LU-5597</del></a> instead of <a href="https://jira.whamcloud.com/browse/LU-5997" title="NULL pointer dereferecing in class_process_proc_seq_param() on lctl conf_param" class="issue-link" data-issue-key="LU-5997"><del>LU-5997</del></a>.
