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:

   Code Block
   # yum -y groupinstall "Development Tools"

   
   

   Info
   title 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. 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

   
   

2. 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

   
   

3. Install EPEL 7:

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

   
   

4. Install additional packages:

   Code Block
   # 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:

   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 git:

   Code Block
   $ 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:

   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

1. 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

   
   

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

   ... ...

5. 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

1. Configure Lustre source:

   Code Block

   $ 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:

   Code Block

   $ 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:

   Code Block

   $ 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/:

# 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.

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.

   
   

   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

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


   Code Block

   # FSTYPE=zfs /usr/lib64/lustre/tests/llmount.sh Stopping clients: onyx-21vm5.onyx.whamcloud.com /mnt/lustre (opts:) Stopping clients: onyx-21vm5.onyx.whamcloud.com /mnt/lustre2 (opts:) Loading modules from /usr/lib64/lustre/tests/.. detected 1 online CPUs by sysfs libcfs will create CPU partition based on online CPUs debug=vfstrace rpctrace dlmtrace neterror ha config ioctl super lfsck subsystem_debug=all gss/krb5 is not supported Formatting mgs, mds, osts Format mds1: lustre-mdt1/mdt1 Format ost1: lustre-ost1/ost1 Format ost2: lustre-ost2/ost2 Checking servers environments Checking clients onyx-21vm5.onyx.whamcloud.com environments Loading modules from /usr/lib64/lustre/tests/.. detected 1 online CPUs by sysfs libcfs will create CPU partition based on online CPUs debug=vfstrace rpctrace dlmtrace neterror ha config ioctl super lfsck subsystem_debug=all gss/krb5 is not supported Setup mgs, mdt, osts Starting mds1: lustre-mdt1/mdt1 /mnt/lustre-mds1 Commit the device label on lustre-mdt1/mdt1 Started lustre-MDT0000 Starting ost1: lustre-ost1/ost1 /mnt/lustre-ost1 Commit the device label on lustre-ost1/ost1 Started lustre-OST0000 Starting ost2: lustre-ost2/ost2 /mnt/lustre-ost2 Commit the device label on lustre-ost2/ost2 Started lustre-OST0001 Starting client: onyx-21vm5.onyx.whamcloud.com: -o user_xattr,flock onyx-21vm5.onyx.whamcloud.com@tcp:/lustre /mnt/lustre UUID 1K-blocks Used Available Use% Mounted on lustre-MDT0000_UUID 130688 1792 126848 1% /mnt/lustre[MDT:0] lustre-OST0000_UUID 343936 1664 340224 0% /mnt/lustre[OST:0] lustre-OST0001_UUID 343936 1408 340480 0% /mnt/lustre[OST:1] filesystem_summary: 687872 3072 680704 0% /mnt/lustre Using TIMEOUT=20 seting jobstats to procname_uid Setting lustre.sys.jobid_var from disable to procname_uid Waiting 90 secs for update disable quota as required

   
   

2. 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.
