I have an juju openstack cluster version wallaby. We used the neutron ml2/ovn plugin for the network.
But the problem is, Whenever the ovn-sb leader changes the neutron-ovn-metadata agent throws an 404 error.
We set the ovn inactivity probe to 6000 and ovsdb_timeout to 180. But still i am facing this issue.
After the ovn-sb leader successfully changed, the neutron-ovn-metadata starts working.
In between the leader changing process, we are facing the downtime for some vms not all the vms.
Kindly , advise me how to resolve it.
