Installing a kernel or module is an option if necessary, though we are also supporting afs and lustre on the same kernel (RHEL 6 based). The purpose of this is to gather accurate metrics on the workload types we run to feed into what hardware we need to buy. Can anyone give me any pointers as to how to proceed?
