Hi,
I see why sb-db broke at 1568th port-binding.
The 1568th datapath-binding in sb-db references the same
_uuid : 108cf745-db82-43c0-a9d3-afe27a41e4aa
external_ids : {logical-switch="8a5d1d3c-e9fc-4cbe-a461-98ff838e6473",
name=neutron-e907dc17-f1e8-4217-a37d-86e9a98c86c2, name2=net-97-192}
tunnel_key : 1567
_uuid : d934ed92-2f3c-4b31-8a76-2a5047a3bb46
external_ids : {logical-switch="8a5d1d3c-e9fc-4cbe-a461-98ff838e6473",
name=neutron-e907dc17-f1e8-4217-a37d-86e9a98c86c2, name2=net-97-192}
tunnel_key : 1568
I don't believe this is supposed to happen. Any idea how could it happen?
Then ovn-northd is stuck in trying to delete this duplication, and it ignores
all the following updates.
That caused out-of-sync between nb-db and sb-db.
Any way I can fix it manually, like with ovn-sbctl to delete it?
Thanks!
Tony

Subject: [ovs-dev] OVN nb-db and sb-db out of sync
Hi,
During a scaling test where 4000 networks are created from OpenStack, I see that
nb-db and sb-db are out of sync. All 4000 logical switches and 8000 LS ports
(GW port and service port of each network) are created in nb-db. In sb-db,
only 1567 port-bindings, 4000 is expected.
[root@ovn-db-2 ~]# ovn-nbctl list nb_global
_uuid : b7b3aa05-f7ed-4dbc-979f-10445ac325b8
connections : []
external_ids : {"neutron:liveness_check_at"="2020-07-22
04:03:17.726917+00:00"}
hv_cfg : 312
ipsec : false
name : ""
nb_cfg : 2636
options : {mac_prefix="ca:e8:07",
svc_monitor_mac="4e:d0:3a:80:d4:b7"}
sb_cfg : 2005
ssl : []
[root@ovn-db-2 ~]# ovn-sbctl list sb_global
_uuid : 3720bc1d-b0da-47ce-85ca-96fa8d398489
connections : []
external_ids : {}
ipsec : false
nb_cfg : 312
options : {mac_prefix="ca:e8:07",
svc_monitor_mac="4e:d0:3a:80:d4:b7"}
ssl : []
Is there any way to force ovn-northd to rebuild sb-db to sync with nb-db,
like manipulating nb_cfg or anything else? Note, it's 3-node RAFT cluster for
both
nb-db and sb-db.
Is that "incremental update" implemented in 20.03?
If not, in which release it's going to be available?
Thanks!
Tony
