I think we are missing the original context here. Where was this issue
reported, mind pointing it out for us please ?

Cheers,

Hi Martin,

I met exactly the same issue with yours, could you please show some details
about security groups deleting, resyncing and recreating? cause I cleared
DEFAULT security group and add 'ovn-sync-mode=repair' in config file then
restarted the neutron-server, but didn't work out.

best regards

Hi Numan,

the security groups were the issue, I deleted them in Openstack, resynced and 
recreated them.

Thanks for your help.

best regards,
 martin

​Looks like the Northbound db is not in sync with neutron db.
Can you run the command "ovn-nbctl list Address_Set" and see if there is a
row for the each of the security groups ?

If you see the ovn northbound db is not in sync, you can sync it by either
running the neutron-ovn-db-sync util or by restarting the neutron-server
after setting ovn-sync-mode=repair in /etc/neutron/plugins/ml2/ml2_conf.ini

Do you see the same issue with devstack ?

Thanks
Numan
