I can only speak for the dlm part of that. Between different distributions, I'd call it luck :) Within the context of one distribution things shouldn't break if the distribution is doing it's job. Upstream, with no distribution context, I'm certainly aware of when compatibility breaks between dlm_controld and corosync and between different dlm_controld versions on nodes. I try to avoid it, but there are unpredictable reasons that it can break. Dave -- Linux-cluster mailing list Linux-cluster@redhat.com https://www.redhat.com/mailman/listinfo/linux-cluster
