It worked! I didn't knew cman_tool do not use corosync.conf. Setting udpu in cluster.conf made it work again. I am trying to migrate the bindnetaddr option from corosync.conf to cluster.conf but couldn't make it work. I want to use this interface for corosync traffic. inet addr:10.76.125.236 Bcast:10.76.125.239 Mask:255.255.255.240 In man cluster.conf says the last octect must be 0. But despite ccs_config validate says it is ok, the cman_tool fails.
