Purpose

Describe the steps you need to build and test a Lustre system (MGS, MDT, MDS, OSS, OST, client) with ZFS from the master branch on a x86_64, RHEL/CentOS 7.3 machine.

Prerequisite

• A newly installed RHEL/CentOS 7.3 x86_64 machine connected to the internet.
• EPEL Repository: this is a convenient source for git.
• NOTE It is suggested that you have at least 1GB of memory on the machine you are using for the build.
• NOTE Verify that selinux is disabled.

Overview

This document walks through the steps of building ZFS, building Lustre and running a basic test of the complete system. 

Procedure

The procedure requires that a OS is setup for development - this includes Lustre sources, and build tools. 

Provision machine and installing dependencies.

Once RHEL 7.3 is newly installed on rhel-master login as user root.

1. Install the kernel development tools:

   # yum -y groupinstall "Development Tools"

   Problem with installing 'Development Tools'

   If the Development Tools group is not be available for some reason, you may find the following list if individual packages necessary to install.

   # yum -y install automake xmlto asciidoc elfutils-libelf-devel zlib-devel binutils-devel newt-devel python-devel hmaccalc perl-ExtUtils-Embed rpm-build make gcc redhat-rpm-config patchutils git

2. Install additional dependencies:

   # yum -y install xmlto asciidoc elfutils-libelf-devel zlib-devel binutils-devel newt-devel python-devel hmaccalc perl-ExtUtils-Embed bison elfutils-devel audit-libs-devel kernel-devel libattr-devel libuuid-devel libblkid-devel libselinux-devel libudev-devel

3. Install EPEL 7:

   # rpm -ivh http://download.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm

4. Install additional packages:

   # yum -y install pesign numactl-devel pciutils-devel ncurses-devel libselinux-devel fio

Preparing the Lustre source.

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

   # useradd -m build

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

   # su build $ cd $HOME

3. Get the MASTER branch from git:

   $ git clone git://git.whamcloud.com/fs/lustre-release.git $ cd lustre-release

4. Run sh ./autogen.sh to generate the configure script.

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

   $ 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' $

Prepare ZFS for Lustre

1. Get SPL and ZFS sources from Github:

   $ 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:

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

   This will end with:

   ... ... 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:

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

4. Build ZFS:

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

   This will end with:

5. Install the ZFS packages. They are required dependencies to build Lustre:

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

Configure and build Lustre

1. Configure Lustre source:

   $ su build $ cd ~/lustre-release/ $ ./configure ... ... config.status: executing depfiles commands config.status: executing libtool commands   CC:            gcc LD:            /usr/bin/ld -m elf_x86_64 CPPFLAGS:      -include /localhome/build/lustre-release/undef.h -include /localhome/build/lustre-release/config.h -I/localhome/build/lustre-release/libcfs/include -I/localhome/build/lustre-release/lnet/include -I/localhome/build/lustre-release/lustre/include CFLAGS:        -g -O2 -Wall -Werror EXTRA_KCFLAGS: -include /localhome/build/lustre-release/undef.h -include /localhome/build/lustre-release/config.h  -g -I/localhome/build/lustre-release/libcfs/include -I/localhome/build/lustre-release/lnet/include -I/localhome/build/lustre-release/lustre/include   Type 'make' to build Lustre.

2. Make RPMs:

   $ make rpms ... ... Checking for unpackaged file(s): /usr/lib/rpm/check-files /tmp/rpmbuild-lustre-build-l84Ao2RN/BUILDROOT/lustre-2.9.51_45_g3b3eeeb-1.x86_64 Wrote: /tmp/rpmbuild-lustre-build-l84Ao2RN/RPMS/x86_64/lustre-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm Wrote: /tmp/rpmbuild-lustre-build-l84Ao2RN/RPMS/x86_64/kmod-lustre-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm Wrote: /tmp/rpmbuild-lustre-build-l84Ao2RN/RPMS/x86_64/kmod-lustre-osd-zfs-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm Wrote: /tmp/rpmbuild-lustre-build-l84Ao2RN/RPMS/x86_64/lustre-osd-zfs-mount-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm Wrote: /tmp/rpmbuild-lustre-build-l84Ao2RN/RPMS/x86_64/lustre-tests-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm Wrote: /tmp/rpmbuild-lustre-build-l84Ao2RN/RPMS/x86_64/kmod-lustre-tests-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm Wrote: /tmp/rpmbuild-lustre-build-l84Ao2RN/RPMS/x86_64/lustre-iokit-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm Wrote: /tmp/rpmbuild-lustre-build-l84Ao2RN/RPMS/x86_64/lustre-debuginfo-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm Executing(%clean): /bin/sh -e /tmp/rpmbuild-lustre-build-l84Ao2RN/TMP/rpm-tmp.qsc8Zw + umask 022 + cd /tmp/rpmbuild-lustre-build-l84Ao2RN/BUILD + cd lustre-2.9.51_45_g3b3eeeb + rm -rf /tmp/rpmbuild-lustre-build-l84Ao2RN/BUILDROOT/lustre-2.9.51_45_g3b3eeeb-1.x86_64 + rm -rf /tmp/rpmbuild-lustre-build-l84Ao2RN/TMP/kmp + exit 0 Executing(--clean): /bin/sh -e /tmp/rpmbuild-lustre-build-l84Ao2RN/TMP/rpm-tmp.vzndd5 + umask 022 + cd /tmp/rpmbuild-lustre-build-l84Ao2RN/BUILD + rm -rf lustre-2.9.51_45_g3b3eeeb + exit 0

3. You should now have build the following, similarly named, RPMs:

   $ ls *.rpm kmod-lustre-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm kmod-lustre-osd-zfs-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm kmod-lustre-tests-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm lustre-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm lustre-2.9.51_45_g3b3eeeb-1.src.rpm lustre-debuginfo-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm lustre-iokit-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm lustre-osd-zfs-mount-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm lustre-tests-2.9.51_45_g3b3eeeb-1.el7.centos.x86_64.rpm

Installing Lustre.

Change to root and Change directory into ~build/lustre-release/:

Disable SELinux (Lustre Servers)

SELinux, which is on by default in RHEL/CentOS, will prevent the format commands for the various Lustre targets from completing.  Therefore you must either disable it or adjust the settings.  These instructions explain how to disable it.

1. Run  getenforce to see if SELinux is enabled.  It should return 'Enforcing' or 'Disabled'.
2. To disable it, edit /etc/selinux/config and change the line 'selinux=enforcing' to 'selinux=disabled'.

3. Finally, reboot your system.

   
   

   # vi /etc/selinux/config   ---- # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of these two values: # targeted - Only targeted network daemons are protected. # strict - Full SELinux protection. SELINUXTYPE=targeted --- # shutdown -r now

Testing

Run "FSTYPE=zfs /usr/lib64/lustre/tests/llmount.sh" to start a test mount with the new modules:


...

You will now have a Lustre filesystem available at /mnt/lustre for testing.  Note that this is just a temporary filesystem for testing purposes and will be reformatted the next time llmount.sh is run.

Centos 8

To prepare the build on CentOS 8 you need to install additionally these packages:
