Because cman is attempted to manage the cluster, I was wondering if there could be any confusion/conflict with Heartbeat Linux-HA (http://www.linux-ha.org/), which is used to manage DRBD ? Or maybe there is a simple, minimalist configuration to cman that only allows to take advantage of distributed/clustered lvm? This would be without all the "cluster management" features that would actually be dedicated to Hearbeat Linux-HA. -- Maxim Doucet - www.alamaison.fr sys admin @ la maison
