Hello Edgar, CS is needed because it contains the service (cman) that configures the participation of nodes in your cluster and also enables your nodes to communicate about changes they want to do an the shared filesystem. Also it contains the method to remove failing nodes from participating in your cluster. This all is mandatory for a cluster filesystem. Please go ahead and read the available documentation if you have further interests in it here: http://sourceware.org/cluster Hope this helps, Marc Am Dienstag, den 22.09.2009, 12:51 +0200 schrieb Edgar Matzinger: --8<-- > what's the point in that?
