Hello, I am trying to install a cluster. After I run /etc/init.d/ccsd start (and get OK) I run: cman_tool join and I get: cman_tool: No multicast address for IPv6 node host4 I am not using IPV6 and do not want to use IPV6; nor did I configured the cluster to use IPV6 anywhere. and cat /proc/cluster/status shows: ... ... Cluster name: Cluster ID: 0 Cluster Member: No Membership state: Not-in-Cluster Any idea why this error message ?
