Building the lustre client RPMs for the current kernel.

  • On a base install of Scientific Linux 6.3, install the latest kernel and all pre-reqs.
%STARTCONSOLE% yum update yum groupinstall 'Development tools' yum install expect %ENDCONSOLE%

  • Edit /etc/selinux/config and disable selinux:
%STARTCONSOLE% SELINUX=disabled %ENDCONSOLE%

  • Reboot.

  • Install the lustre client source RPM:
%STARTCONSOLE% rpm -ivhU http://downloads.whamcloud.com/public/lustre/lustre-1.8.8-wc1/el6/client/RPMS/x86_64/lustre-client-source-1.8.8-wc1_2.6.32_220.17.1.el6.x86_64_gbc88c4c.x86_64.rpm %ENDCONSOLE%

  • Switch to the source directory, compile the lustre client code and build the RPMs.
%STARTCONSOLE% cd /usr/src/lustre-1.8.8 ./configure make make rpms %ENDCONSOLE%

  • Install the client either by:
%STARTCONSOLE% cd /root/rpmbuild/RPMS/x86_64 rpm -ivhf lustre-client-1.8.8-wc1_2.6.32_279.14.1.el6.x86_64_gbc88c4c.x86_64.rpm lustre-client-modules-1.8.8-wc1_2.6.32_279.14.1.el6.x86_64_gbc88c4c.x86_64.rpm %ENDCONSOLE%

  • or create a repository with these RPMs and (see also "Activating a lustre client node" below):
%STARTCONSOLE% yum install lustre-client %ENDCONSOLE%
 

Activating a lustre client node.

  • Configure the lustre network by creating "/etc/modpobe.d/lustre-lnet.conf". Assuming the "ethmlx" network interface is on the same layer 2 network as the lustre filesystem (10.20.3.nnn), the configuration file should contain:
