My apologies if this is a stupid question, but I'm not familiar with how kernel updates and kernel modules interact. I see that there are some kernel updates available via yum: ============================================================================ = Package Arch Version Repository Size ============================================================================ = Installing: kernel x86_64 2.6.9-22.0.2.EL update 10 M kernel-devel x86_64 2.6.9-22.0.2.EL update 3.5 M kernel-smp x86_64 2.6.9-22.0.2.EL update 9.6 M Updating: kernel-smp-devel x86_64 2.6.9-22.0.2.EL update 3.6 M Will updating to this new kernel cause problems with the cman-kernel, GFS-kernel, or dlm-kernel modules? Will yum warn me about those types of issues? As a more generic question, is it generally safe to let "yum update" install the updates it finds? Thanks, Bowie
