and my OCFS2 config:

cat /etc/ocfs2/cluster.conf
node:
        ip_port = 7777
        ip_address = 192.168.10.31

        cluster = ocfs2

node:
        ip_port = 7777
        ip_address = 192.168.10.32
        number = 2
        name = nvt-mta-02
        cluster = ocfs2

cluster:
        node_count = 2
        name = ocfs2
