Purpose

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

...

1. Get the kernel source. First create the directory structure, then get the source from the RPM. Create a .rpmmacros file to install the kernel source in our user directory:

   Code Block
   $ cd $HOME $ mkdir -p kernel/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS} $ cd kernel $ echo '%_topdir %(echo $HOME)/kernel/rpmbuild' > ~/.rpmmacros

2. Install the kernel source:

   Code Block
   $ rpm -ivh http://vault.centos.org/7.3.1611/updates/Source/SPackages/kernel-3.10.0-514.2.2.el7.src.rpm

    

    

   
   

   
   

3. Prepare the source using rpmbuild:

   Code Block
   $ cd ~/kernel/rpmbuild $ rpmbuild -bp --target=`uname -m` ./SPECS/kernel.spec

   
   This will end with:

   Code Block
   ... + make ARCH=x86_64 oldnoconfig scripts/kconfig/conf --olddefconfig Kconfig # # configuration written to .config # + echo '# x86_64' + cat .config + find . '(' -name '*.orig' -o -name '*~' ')' -exec rm -f '{}' ';' + find . -name .gitignore -exec rm -f '{}' ';' + cd .. + exit 0

...

1. Start building the kernel with rpmbuild:

   Code Block
   $ cd ~/kernel/rpmbuild $ buildid="_lustre" # Note: change to any string that identify your work $ rpmbuild -ba --with firmware --target x86_64 --with baseonly \ --define "buildid ${buildid}" \ ~/kernel/rpmbuild/SPECS/kernel.spec

2. A successful build will return:

   Code Block
