lustre client 2.3 asking for lustre-backend-fs

Bug Major Resolved Won't Fix WC Triage amit bajaj llnl Sat, 20 Apr 2013 15:46:41 +0000 Sat, 9 Oct 2021 06:26:03 +0000 Sat, 9 Oct 2021 06:26:03 +0000 Lustre 2.3.0 0 2 <p>The lustre-backend-fs RPM is lustre-ldiskfs. </p> <p>yes but do we really need to install on client?<br/> second when installing lustre-ldiskfs , it is asking for ldisksfsprogs*.oral, e2fsprogs is already installed, </p> <p>Yes, lustre's build system is broken in a number of ways that I've long been trying to fix over in <a href="https://jira.whamcloud.com/browse/LU-1199" title="lustre build system overhaul" class="issue-link" data-issue-key="LU-1199"><del>LU-1199</del></a>. Bringing sanity to the src rpm is my primary goal. Unfortunately, that work didn't make it into 2.4. Maybe by 2.5 things will be better.</p> <p>In the mean time, you need to know a couple of things:</p> <p>1) The lustre-client-*.src.rpm is <em>not</em> really just the lustre client. It really contains the full source of lustre.<br/> 2) Conversely, lustre-*.src.rpm is not lacking the client code, it also contains the full sources.</p> <p>If our build system was sane, we would have only a single source rpm (more or less) and then just have good options that could be passed in on the rpmbuild command line to enable or disable the various options.</p> <p>To enable the client-only build of lustre, you need to enable the "is_client" macro in the spec file. Granted, "is_client" is really misnamed. You are <em>always</em> building the lustre client code. Really "is_client" disables the build of the server code. And that is the root of your issue. You need to disable the build of the server code to eliminate the rpm "Requires: lustre-backend-fs".</p> <p>But wait! Don't set is_client directly. That would be too sane. Instead, you need to change the package name.</p> <p>So try this:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>rpmbuild --define "lustre_name lustre-client" &lt;source rpm&gt;</pre> </div></div> <p>I can't claim that it will be sufficient, but it is at least the starting point you'll need to build client-only rpms from the source rpm.</p> Development Rank 1|hzvolb: Rank (Obsolete) 7808 Severity
