1. Create a user build with the home directory /home/build

   Code Block
   # useradd -m build

2. Switch to the user build and change to the build $HOME directory.

   Code Block
   # su build $ cd $HOME

3. Get the MASTER branch from HPDD git.

   Code Block
   $ git clone git://git.hpdd.intel.com/fs/lustre-release.git $ cd lustre-release

4. Run sh ./autogen.sh

5. Resolve any outstanding dependencies until autogen.sh completes successfully. Success will look like:

   Code Block
   $ sh ./autogen.sh configure.ac:10: installing 'config/config.guess' configure.ac:10: installing 'config/config.sub' configure.ac:12: installing 'config/install-sh' configure.ac:12: installing 'config/missing' libcfs/libcfs/autoMakefile.am: installing 'config/depcomp' $

ZFS for Lustre

1. Get SPL and ZFS from github

   Code Block
   $ cd $HOME  $ git clone https://github.com/zfsonlinux/spl.git $ git clone https://github.com/zfsonlinux/zfs.git $ $ cd spl $ ./autogen.sh $ cd ../zfs $ ./autogen.sh $ cd $HOME

2. Build SPL for kABI-tracking kmod

   Code Block
   $ cd $HOME/spl $ ./configure --with-spec=redhat $ make pkg-utils pkg-kmod

   This will end with:

   Code Block

   ... ... Checking for unpackaged file(s): /usr/lib/rpm/check-files /tmp/spl-build-build-FxdXBfej/BUILDROOT/spl-kmod-0.7.0-rc3.el7.centos.x86_64 Wrote: /tmp/spl-build-build-FxdXBfej/RPMS/x86_64/kmod-spl-0.7.0-rc3.el7.centos.x86_64.rpm Wrote: /tmp/spl-build-build-FxdXBfej/RPMS/x86_64/kmod-spl-devel-0.7.0-rc3.el7.centos.x86_64.rpm Wrote: /tmp/spl-build-build-FxdXBfej/RPMS/x86_64/spl-kmod-debuginfo-0.7.0-rc3.el7.centos.x86_64.rpm Executing(%clean): /bin/sh -e /tmp/spl-build-build-FxdXBfej/TMP/rpm-tmp.NhMrJh + umask 022 + cd /tmp/spl-build-build-FxdXBfej/BUILD + cd spl-0.7.0 + rm -rf /tmp/spl-build-build-FxdXBfej/BUILDROOT/spl-kmod-0.7.0-rc3.el7.centos.x86_64 + exit 0 Executing(--clean): /bin/sh -e /tmp/spl-build-build-FxdXBfej/TMP/rpm-tmp.FDCzZG + umask 022 + cd /tmp/spl-build-build-FxdXBfej/BUILD + rm -rf spl-0.7.0 + exit 0

   At this point you should have SPL package in ~build/spl

3. Install the SPL packages. They are required dependencies to build zfs

   Code Block
   As root, go to ~build/spl and install the packages # yum -y localinstall *.x86_64.rpm

4. Build ZFS

   Code Block
   $ su build $ cd $HOME/zfs $ ./configure --with-spec=redhat $ make pkg-utils pkg-kmod

   This will end with:

   Code Block

You can have different ways to prepare a patched kernel for Lustre. The easier method is to download built RPM packages from build.hpdd.intel.com. For example, if you're running el7, you should download the packages from here: https://build.hpdd.intel.com/view/Non-Reviews/job/lustre-master/arch=x86_64,build_type=server,distro=el7,ib_stack=inkernel/lastSuccessfulBuild/artifact/artifacts/RPMS/x86_64/ at the time when this page is written. You're going to need the packages starting with 'kernel-'. After new kernel packages are downloaded, you can skip the following few steps and go to the section 'Installing the Lustre kernel and rebooting'.
