Version-Release number of selected component (if applicable):

[root@dell-per730-19 openvswitch]# rpm -qa | grep openvswitch
kernel-kernel-networking-openvswitch-ovn_ha-1.0-37.noarch
openvswitch-ovn-host-2.9.0-110.el7fdp.x86_64
openvswitch-2.9.0-110.el7fdp.x86_64

[root@dell-per730-19 openvswitch]#

How reproducible:
everytime

Steps to Reproduce:
1.setup ovn_cluster topo,node A is slave node
2.stop cluster topo and use node A to be ovn server
3.ovn report error if try to configure ovn-nbctl unless delete the file /etc/openvswitch/ovnnb-active.conf

[root@dell-per730-19 openvswitch]# ovn-nbctl ls-add s888
ovn-nbctl: transaction error: {"details":"insert operation not allowed when database server is in read only mode","error":"not allowed"}
[root@dell-per730-19 openvswitch]# rm -f ovnnb-active.conf
[root@dell-per730-19 openvswitch]# systemctl restart ovn-northd
[root@dell-per730-19 openvswitch]# ovn-nbctl ls-add s888
[root@dell-per730-19 openvswitch]# ovn-nbctl ls-list
