As an experiment, I've tried just loading the dlm module on a node with no cluster services running and confirmed that dlm-control is being created by udev. I must admit - I'm pretty confused now about the role of libdlm. Since it turns out that I've been running a 4U4 cluster without the dlm package installed (and so no libdlm) and, until this morning, my 4U5 cluster in the same state, I'm wondering: What uses libdlm?
