It shall be possible to do this type of work by administrators without knowledge of lustre internals.<br/> There are several mails on lustre-discuss list reporting lnetctl is not in rpm.</p> <p>I had to explicitly use flags as listed below to get lnetctl:<br/> rpmbuild --rebuild --without servers --with lnet-dlc --with lustre-utils ./lustre-2.10.2-1.src.rpm</p> <p>I did not try rpm rebuild for SLF 7.4 as distro version worked for me.</p> <p>The other aspect, we have to document rpm rebuild procedure.<br/> There are clear and detailed instructions on client rebuild on Cray website for their distro. I can not easily find "rebuild" in lustre manual linked from lustre.org. <br/> There are detailed instructions on lustre wiki; they have to be updated with lnet-dlc lustre-utils until rpm build fixed.</p> OS: SLF 6.8<br/> Kernel: 2.6.32-642.15.1.el6.x86_64<br/> LU-10556

lustre client rebuild not building lnetctl

Bug Minor Resolved Fixed James A Simmons Alex Kulyavtsev Tue, 23 Jan 2018 22:29:07 +0000 Wed, 28 Mar 2018 17:11:38 +0000 Mon, 26 Mar 2018 21:06:15 +0000 Lustre 2.10.2 Lustre 2.11.0 0 5 <p>Do you have libyaml-devel package installed?</p> <p>Yes, both libyaml libyaml-devel installed - I learned that during the server build.<br/> config log explicitly shows that "configure" got libyaml* during rpm build.</p> <p>I rebuilt rpm with / without disable-dlc flag and it made the difference so it is not related to host configuration (with libyaml present).</p> <p>config.status shows for the plain rebuild "--without servers" and without explicitly setting flags lnet-dlc that enable_dlc is set no (disabled) by default and this prevents building lnetctl.</p> <p>aclocal.m4 :</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre># LN_CONFIG_DLC # # Configure dlc if enabled # # if libyaml is set (IE libyaml installed) and enable_dlc = yes then build # dlc other wise (IE if libyaml is not set or enable_dlc = no) then don't # build dlc. </pre> </div></div> <p>Because distro rpm has dlc enabled, we shall have set enable_dlc = yes by default (at least when libyaml installed) and explicitly disable dlc when it is not needed and/or libyaml not installed. </p> <p>At this point I'm OK with workaround; </p> <p>It is important to have client rpm to be rebuild with the same configuration as rpm in distro without unpacking and digging into source rpm.</p> <p>If we are marking the <tt>lctl</tt> versions of the commands deprecated in 2.11 (per <a href="https://jira.whamcloud.com/browse/LU-10003" title="lnetctl error &quot;cannot add network: invalid argument&quot;" class="issue-link" data-issue-key="LU-10003">LU-10003</a>) it makes sense to have <tt>enable_dlc</tt> set by default.</p> <p>Alex, if you already have a patch for this, could you please submit it to Gerrit so we can land that for 2.11 and backport it for a 2.10 maintenance release.</p> <p>James, I see that in <a href="https://jira.whamcloud.com/browse/LU-9897" title="Tracking of lustre library improvements." class="issue-link" data-issue-key="LU-9897">LU-9897</a> there is a change to the <tt>lustre.spec.in</tt> file that removes the conditional build of <tt>liblnetconfig.so</tt> but it doesn't add <tt>libyaml</tt> or <tt>yaml-devel</tt> (or whatever) package to the <tt>Build-requires:</tt> line.  That should probably be added.</p> <p>Yep. I missed adding that dependency. BTW while working with the <a href="https://jira.whamcloud.com/browse/LU-9897" title="Tracking of lustre library improvements." class="issue-link" data-issue-key="LU-9897">LU-9897</a> patch I noticed Debian/Ubuntu have no dependencies in its build files!!!! I was waiting for Martin's Ubuntu server patches to land first before I fix that.</p> <p>Minh Diep (minh.diep@intel.com) uploaded a new patch: <a href="https://review.whamcloud.com/31710" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/31710</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-10556" title="lustre client rebuild not building lnetctl" class="issue-link" data-issue-key="LU-10556"><del>LU-10556</del></a> build: add require libyaml and zlib<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: ac4da53c0f66b2f77b9f502bac6f4b26a45f2ceb</p> <p>I confirm /usr/sbin/lnetctl present in lustre-client rpm built from  lustre-2.11.0_RC1_1_gac4da53-1.src.rpm</p> <p><tt>on SLF 7.4:  </tt><tt>3.10.0-693.11.1.el7.x86_64</tt></p> <p><tt>and SLF 6.8: </tt><tt>2.6.32-642.15.1.el6.x86_64</tt></p> <p> </p> <p>I grabbed source rpm from build server (artifact of build triggered by patch 31710)</p> <p><tt>wget <a href="http://build.lustre.org/downloads/31710/1/centos/7.2/SRPM/lustre-2.11.0_RC1_1_gac4da53-1.src.rpm" class="external-link" target="_blank" rel="nofollow noopener">http://build.lustre.org/downloads/31710/1/centos/7.2/SRPM/lustre-2.11.0_RC1_1_gac4da53-1.src.rpm</a></tt></p> <p><tt>DIR=../downloads/build.lustre.org</tt></p> <p><tt>SRPM=lustre-2.11.0_RC1_1_gac4da53-1.src.rpm </tt></p> <p><tt>rpmbuild  --rebuild --without servers --define 'configure_args --disable-gss --disable-gss-keyring' $DIR/$SRPM</tt></p> <p> </p> <p>There is unrelated gss issue on SLF 7 node (it can be also some rpms are installed/missing).</p> <p>I had to add flags on SLF7 node to resolve error:</p> <p><tt>--define 'configure_args --disable-gss --disable-gss-keyring'</tt></p> <p><tt>File not found: /root/rpmbuild/BUILDROOT/lustre-2.11.0_RC1_1_gac4da53-1.x86_64/etc/request-key.d/lgssc.conf</tt></p> <p> </p> <p>Built completed OK on SLF 6.8 node.</p> <p> </p> <p>I guess gss is disabled by default in lustre.spec.in .
