Note

This walk-thru is targeting developers who want to explore the bleeding edge of Lustre. If you are evaluating Lustre for production, you should choose a Lustre Release.

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.

Install the kernel development tools:

Code Block
# yum -y groupinstall "Development Tools"

...

titleProblem 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.

Code Block
# 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

Install additional dependencies:

Code Block
# 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

Install EPEL 7:

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

Install additional packages:

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

Preparing the Lustre source.

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

Code Block
# useradd -m build

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

Code Block
# su build
$ cd $HOME

Get the MASTER branch from git:

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

...

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'
$

Prepare ZFS for Lustre

Get SPL and ZFS sources 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

...

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
...
...

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

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

Build ZFS:

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

This will end with:

Code Block

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

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

Configure and build Lustre

Configure Lustre source:

Code Block
$ su build
$ cd ~/lustre-release/
$ ./configure
...
...

Type 'make' to build Lustre.

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

Code Block
$ ls *.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/:

Code Block
# yum localinstall *.x86_64.rpm

 

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.

...

Finally, reboot your system.

Code Block
# 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:
