But, this sentence can be easier to understand: Two-node clusters are a special case. Because a two-node cluster only needs two nodes to establish quorum, the only way to add a third node is to shut down the cluster, add the third node into your /etc/cluster/cluster.conf file (either by hand or system-config-cluster), copy it into the newly joined cluster, and restart all of the nodes. (the two_node="1" will be removed automatically by system-config-cluster). -- Fajar Priyanto | Reg'd Linux User #327841 | Linux tutorial http://linux2.arinet.org 5:07pm up 8:33, 2.6.18.2-34-default GNU/Linux Let's use OpenOffice. http://www.openoffice.org
