If the lustre-client RPMs need to be rebuild against a different client kernel, follow this procedure.

Warning

title	LU-1076

There is currently a problem rebuilding the lustre-client rpms. Fixing this issue is being tracked on LU-1076: http://jira.whamcloud.com/browse/LU-1076.

Procedure

NOTE This procedure assumes you are using a RPM based distribution. For example RHEL or CentOS.

Install the following packages:
- kernel-devel
- rpm-build
- make
  Note
  title kernel versions
  If you are not currently booted into the kernel provided by kernel-devel package review the trouble-shooting section below.
Obtain the lustre-client .src.rpm (from the SRPMS section of the download site).
On the build node, run the command:

Code Block
# rpmbuild --rebuild <lustre version>.src.rpm

NOTE The resulting RPMS may be named 'lustre-modules' rather than 'lustre-client-modules'

Follow the procedure above, substituting the code below for step 3.

Code Block
# rpmbuild --rebuild --without servers <lustre version>.src.rpm

To build against a different kernel to the one currently running, you need to provide the chosen kernel to rpmbuild. For example:

Code Block
rpmbuild --define 'kversion 2.6.32-220.4.1.el6.x86_64' --define 'kdir /usr/src/kernels/2.6.32-220.4.1.el6.x86_64/' --rebuild lustre-client-2.1.0-2.6.32_131.6.1.el6.x86_64_g9d71fe8.src.rpm
