Hello, As mentioned in the previous post, I have setup my first cluster with 3 nodes running CentOS 5.4. Two nodes are mirrored using DRBD, and that is used as shared storage for cluster. Third node is accessing that shared storage using GNBD. When all three nodes are up and running, everything works well. However, when I need to shutdown one of nodes, I usually can't do it without hanging one or all of nodes, and in most cases I have to use hardware reset :( I tried stopping all services using shared storage (apache web server), and then stopping all cluster related services (cman, clvmd, rgmanager, gnbd_imports, etc.). For some reason, it doesn't work. Can anyone tell me what steps should I take when one of the cluster nodes needs to be restarted?
