    Adjusting partition size

    Problem adding third node to cluster

    Your hosts file (on each node!) must contain information about all nodes in cluster! For example: 192.168.1.6 pvez6.domain.net pvez6 pvelocalhost 192.168.1.7 pvez7.domain.net pvez7 192.168.1.5 pvez5.domain.net pvez5 and so on... Best regards, Gosha
