Listing available resources

crmsh # crm ra classes
pcs   # pcs resource standards

crmsh # crm ra list ocf pacemaker
pcs   # pcs resource agents ocf:pacemaker

Creating a resource

crmsh # crm configure primitive ClusterIP ocf:heartbeat:IPaddr2 \
        params ip=192.168.122.120 cidr_netmask=32 \
        op monitor interval=30s 
pcs   # pcs resource create ClusterIP IPaddr2 ip=192.168.0.120 cidr_netmask=32
