hi all, I''m a beginner with lustre. I have played with an already setup lustre FS for a couple of days. Now I want to roll up my sleeves and do some simple works inside lustre. For example, I want to add some "printk"s in lustre code, and collect some statistic information. But I don''t know where the lustre code is:( "uname -r" gives kernel as "2.6.9.67.0.7.EL_lustre.1.6.5.1". I think the kernel is lustre-patched, but cannot see where lustre codes are. Where can I see the lustre sources ? and where shall I start from? Thanks a lot! -neutron
