Description of problem: When I delete one node and recover it, The 'ovn_host_subnet' is duplicated with another node Version-Release number of selected component (if applicable): How reproducible: always Steps to Reproduce: 1.Set up the cluster with 3 nodes with OVN and set the cidr to 10.128.0.0/14/23 2.Delete one node with ovn_host_subnet is 10.128.0.0/23 3. recover the node by 'systemctl restart atomic-openshiftnode' 4. Check the recovered node 'OVN_host_subnet', found it uses '10.129.0.0./23', but this subnet has been used by another. Actual results: The ovn_host_subnet of those two node are same.
