Hi Thiago,

You can use the "neutron-ovn-db-sync-util" utility to repair the OVN database.
You can run it as "neutron-ovn-db-sync-util --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini"

Make sure to change the mode to repair in ml2_conf.ini or pass the neutron_sync_mode=repair in the command line.

Having said that, neutron-server should repair the OVN database as well.
The sync util and neutron-sever share the same code for sync.

Can you please share the neutron server logs to see what is happening there.
