2021-10-10 19:18:08.384 78 WARNING neutron.plugins.ml2.drivers.ovn.mech_driver.mech_driver [req-18282ec4-8752-4c7b-8cb8-3f54a02377ba - - - - -] Metadata service is not ready for port 5466933e-a22e-4288-b40c-ddc01fe23cfa, check neutron-ovn-metadata-agent status/logs.: neutron.plugins.ml2.drivers.ovn.mech_driver.mech_driver.MetadataServiceReadyWaitTimeoutException
This is due to:
The value about neutron-metadata-proxy-networks of Chassis's external_ids are network_id, and the datapath field of Port_Binding table is the uuid of Datapath_Binding tables.
When call function set_port_status_up, it check self._wait_for_metadata_provisioned_if_needed(port_id)
```
...
try:
n_utils.wait_until_true(
lambda: datapath in
self._sb_ovn.get_chassis_metadata_networks(chassis),
timeout=METADATA_READY_WAIT_TIMEOUT,
exception=MetadataServiceReadyWaitTimeoutException)
except MetadataServiceReadyWaitTimeoutException:
# If we reach this point it means that metadata agent didn't
# provision the datapath for this port on its chassis. Either
# the agent is not running or it crashed. We'll complete the
# provisioning block though.
LOG.warning("Metadata service is not ready for port %s, check"

Get datapath:
def get_logical_port_chassis_and_datapath(self, name):
for port in self._tables['Port_Binding'].rows.values():
if port.logical_port == name:
datapath = str(port.datapath.uuid)
chassis = port.chassis[0].name if port.chassis else None
return chassis, datapath
Get neutron-metadata-proxy-networks:
def get_chassis_metadata_networks(self, chassis_name):
"""Return a list with the metadata networks the chassis is hosting."""
try:
chassis = self.lookup('Chassis', chassis_name)
except idlutils.RowNotFound:
LOG.warning("Couldn't find Chassis named %s in OVN while looking "
"for metadata networks", chassis_name)
return []
proxy_networks = chassis.external_ids.get(
'neutron-metadata-proxy-networks', None)
return proxy_networks.split(',') if proxy_networks else []
I fix it by this way:
def get_logical_port_chassis_and_datapath(self, name):
for port in self._tables['Port_Binding'].rows.values():
if port.logical_port == name:
network_id = utils.get_network_name_from_datapath(
port.datapath)
chassis = port.chassis[0].name if port.chassis else None
return chassis, network_id
