Quick update. I changed the script to create 256 routers first, then set each
of them as gateway.
There is no create and set back to back. It seems working fine now.
It would be good someone can clarify my questions. It seems that it's not
guaranteed that the
object is ready when client get OK response of creation request. Is this
expected?
Thanks!
Tony

Subject: [ovs-dev] OVN: configuration in Neutron DB?
Hi,
In case of integration with OpenStack, for example, when a client requests to
create a network,
is this network configuration saved in both Neutron DB and OVN DB, or OVN DB
only?
Also, when a client gets a network from Neutron API, is the configuration read
from Neutron DB
or OVN DB?
Other than coding, is there any doc about how Neutron OVN ML2 driver works?
I have this script to create 256 routers and set each of them as gateway.
router()
{
local op=$1
for c in `seq 0 1 255`; do
echo "INFO: $op router-$c..."
openstack router $op router-$c
if [ "$op" == "create" ]; then
openstack router set \
--external-gateway public \
--fixed-ip ip-address=10.6.33.$c \
--disable-snat \
router-$c
fi
done
}
I see lots failures from Neutron log when get/show a router. It seems like
that, when setting a router,
the router is not completely ready yet. Is it possible?
After running that script, I see some logical routers in ovn-nb-db don't have
gw_port_id. And there
are some duplications. Here is an example. Each of them has unique UUID.
external_ids : {"neutron:gw_port_id"="", "neutron:revision_number"="1",
"neutron:router_name"=router-255}
external_ids : {"neutron:gw_port_id"="", "neutron:revision_number"="1",
"neutron:router_name"=router-232}
external_ids : {"neutron:gw_port_id"="", "neutron:revision_number"="0",
"neutron:router_name"=router-158}
external_ids : {"neutron:gw_port_id"="", "neutron:revision_number"="0",
"neutron:router_name"=router-158}
external_ids :
{"neutron:gw_port_id"="e52dda53-c914-4ea7-840b-8632a5770680",
"neutron:revision_number"="2", "neutron:router_name"=router-158}
I enabled nb-db debug logging and searched, eg. router-158, it only shows in a
jsonrpc reply message
including 3 router-158, as the above.
Any clues?
Thanks!
Tony
