- download and install kernel debuginfo and debuginfo-common rpms.
- If you know the gerrit review you're looking at then you can follow the links to get to the necessary rpms. The server builds have the kernel-debuginfo and kernel-debuginfo-common rpms
- for client which use the stock kernel, you'll need to get that off centos debuginfo site
- EX: centos 7: http://debuginfo.centos.org/7/x86_64/
- download and install the lustre-debuginfo for the appropriate build
- Again for a gerrit review you can get to it through the build artifacts link on build.hpdd.intel.com
- Instead of installation you can extract the rpms in your local debug directory
- rpm2cpio <rpm> | cpio -idmv
