Examine the contents of the /etc/ocfs2/cluster.conf file: node: name = exam2 cluster = mycluster number = 0
ip_address = 192.168.56.106
ip_port = 7777

node:
name = exam3

cluster = mycluster
number = 1
ip_address = 192.168.56.107
ip_port = 7777
clustr:
name = mycluster
heartbeat_mode = local
node_count = 2

Identify the minimum number of commands issued, in the correct order, to create this file.
1. o2cb add-cluster --heartbeat_mode local mycluster
2. o2cb add-node --ip 192.168.56.107 --number 1 mycluster exam3
3. o2cb add-cluster mycluster
4. o2cb add-node --ip 192.168.56.106 -- number 0 mycluster exam2
5. o0cb config-cluster -node_count 2 mycluster
6. o2cb configure
