commit 3aafeefc8553fd637bad238ee236b1767d8548ea Author: Harald Jensås <[email protected]> Date: Mon Oct 23 17:29:00 2023 +0200 [OVN] DB sync host/physnet - filter on agent_type When syncing hostname and physical networks, filter neutron hosts on agent_type. Only segmenthostmappings for hosts with agent 'OVN Controller agent' should be cleaned up. Since change: I935186b6ee95f0cae8dc05869d9742c8fb3353c3 there is de-duplication of segmenthostmapping updates from agents. If the OVN DB sync clears/deletes mappings for hosts owned by other agents/plugins the mappings are never re-created.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/2040172 Title: [OVN] OvnSbSynchronizer - clean/delete segmenthostmappings for unrelated hosts Status in neutron: Fix Released Bug description: neutron.plugins.ml2.drivers.ovn.mech_driver.ovsdb.ovn_db_sync.OvnSbSynchronizer When the `sync_hostname_and_physical_networks` method run's it will compare host physical_networks to mappings in neutrons `segmenthostmappings` table. Any mappings in neutron that is not seen on OVN chassis is then treated as "stale" and cleaned up. This is problematic when there are other plug-ins/agents involved, for example ML2 networking-baremetal[2]. Any segment-host mapping created for baremetal nodes are deleted from the database. And since there is de-duplication[1] on updates from agents - the segment-host mappings are not re-created unless services are re-started or the baremetal node is deleted and re-created in the ironic service. The OvnSbSynchronizer should not remove mappings unless they belong to OVN hosts.
