Just remove them. Newer debhelper will automatically create conffiles when it sees any files in the /etc tree. </p> <p>2) Ubuntu has a /lib/modules/$(uname)/build symlink but not a source symlink. This meant that $LINUX which is meant to point to a linux source tree ended up pointing to linux-header-$(uname)<del>generic instead. This broke the build. The solution was to add test for linux-source</del>$(uname) before the module symlink.</p> <p>3) Using the real source tree exposed the breakage with setting IB_OPTIONS. Its was set to either "no" or the IB source path, which is the linux source tree. Well Ubuntu stores Module.symvers in the linux-obj area instead. This caused various breakage as well. Now the default behavior is to handle the --with-o2ib="yes" case.</p> <p>4) Missing resource-agent support.</p> <p>5) What still needs to be fixed is ZFS. This is NOT totally fixed. Currently you see this output:</p> <p>checking spl source directory... /usr/src/linux-source-4.15.0/spl</p> <p>checking spl build directory... ls: cannot access '/usr/src/linux-source-4.15.0/spl/<span class="error">[0-9]</span>*/': No such file or directory</p> <p>Not found</p> <p>checking zfs source directory... /usr/src/linux-source-4.15.0/zfs</p> <p>checking zfs build directory... ls: cannot access '/usr/src/linux-source-4.15.0/zfs/<span class="error">[0-9]</span>*/': No such file or directory</p> <p>Not found</p> <p>This is due to the check for <span class="error">[spl|zfs]</span>_config.h which does not exist on Ubuntu systems. So another way will need to be worked out on how to detect of zfs/spl "build". The source is now properly detected.</p> <p> </p> <p>BTW does anyone know if Ubuntu16 creates *.ddeb as well. The *.ddeb are the new debuginfo packages for recent debian/Ubuntu systems.</p> <p>I'm seeing in the latest testing: </p> <p><span class="error">[96614.006917]</span> osd_ldiskfs*: Unknown symbol ldiskfs_orphan_add (err 0)*</p> <p>Give the latest patch a try. I worked out all the kinks for ldiskfs. The only thing missing now is a e2fsprogs for Ubuntu18.</p> <p>The e2fsprogs is one the way. I have a patched e2fsprogs 1.44.3 working on ubuntu18. Need to clean up and consolidate some commits then we are good.</p> <p>With the latest patch all you have to do is install the kernel source tree for Ubuntu to generate lustre server packages.</p> <p>apt-get install linux-source; bunzip2 /usr/src/linux-source-4.15.0.tar.bz2; ...</p> <p>cd lustre-release;./configure;make debs</p> <p>Its should automagically build the server packages. To build only client you need to do configure --disable-server. If no linux source tree is available the default behavior is to build a Ubuntu client. </p> <p>Can you make public your e2fsprog changes? </p> <p>James,</p> <p>The latest e2fsprogs is currently at git.whamcloud.com, master-lustre-test branch</p> <p><a href="https://git.whamcloud.com/?p=tools/e2fsprogs.git;a=shortlog;h=refs/heads/master-lustre-test" class="external-link" target="_blank" rel="nofollow noopener">https://git.whamcloud.com/?p=tools/e2fsprogs.git;a=shortlog;h=refs/heads/master-lustre-test</a></p> <p>I have cloned the repo but when I run : dpkg-buildpackage -rfakeroot -b</p> <p>I see: </p> <p>make<span class="error">[2]</span>: Entering directory '/home/jsimmons/e2fsprogs/debian/BUILD-STD'</p> <p>./util/subst -f ./util/subst.conf ../../lib/dirpaths.h.in lib/dirpaths.h</p> <p>make<span class="error">[2]</span>: ./util/subst: Command not found</p> <p>Makefile:266: recipe for target 'lib/dirpaths.h' failed</p> <p>make<span class="error">[2]</span>: *** <span class="error">[lib/dirpaths.h]</span> Error 127</p> <p>make<span class="error">[2]</span>: Leaving directory '/home/jsimmons/e2fsprogs/debian/BUILD-STD'</p> <p>Makefile:346: recipe for target 'subs' failed</p> <p>Sorry I'm a newbie for this.</p> <p>There is a wiki page for this:</p> <p><a href="https://wiki.whamcloud.com/pages/viewpage.action?pageId=63968116#BuildLustreMASTERwithLdiskfs&ZFSonUbuntu14.04/16.04fromGit-4.)(Optional)Buildingmodifiede2fsprogsforLDISKFSsupport" class="external-link" target="_blank" rel="nofollow noopener">https://wiki.whamcloud.com/pages/viewpage.action?pageId=63968116#BuildLustreMASTERwithLdiskfs&ZFSonUbuntu14.04/16.04fromGit-4.)(Optional)Buildingmodifiede2fsprogsforLDISKFSsupport</a></p> <p>basically what you need to do this clone the repo and checkout the master-lustre-test branch, which is 1.44.3 + lustre related changes.</p> <p>We don't need to download the debian control tarball from ubuntu and untar/replace the ones in the source tree, they are identical.</p> <p>Then just follow the remaining steps in the wiki page:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> sed -i <span class="code-quote">'s/ext2_types-wrapper.h$<span class="code-comment">//g'</span> lib/ext2fs/Makefile.in </span> dpkg-buildpackage -b -us -uc</pre> </div></div> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/32613/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/32613/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-11071" title="Support for Lustre Servers on Ubuntu 18.04 LTS" class="issue-link" data-issue-key="LU-11071"><del>LU-11071</del></a> build: Add server build support for Ubuntu 18.04<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: e41bdca755954beeb47ee6653ed9e140b7338e96</p> <p>We still need to figure out ZFS support but ldiskfs is complete.</p> <p>Including having e2fsprogs support?</p> <p>Yes we need to get the modified e2fsprogs for this as well.
