Miguel, do you know how to remove and re-add the chassis to the southbound db?
(We have to check this to address bug https://bugzilla.redhat.com/1758289 )
"ovn-sbctl chassis-del CHASSIS" will get rid of the chassis / encap.
Afterwards, the ovn-controller will re-register itself on OVN southbound.
There's something weird about your chassis, I see you have listed 3
different chassis IDs on your port IDs:
- ovn-chassis-id="5668499c-7dd0-41ee-bc5d-2e6ee9cd61c3(a)192.168.1.41"
- ovn-chassis-id="25cc77b3-046f-45c5-af0c-ffb2f77d73f1(a)192.168.1.64"
- ovn-chassis-id="baa0199e-d1a4-484c-af13-a41bcad19dbc(a)192.168.1.90"
From your 'ovs-vsctl show' I can see the IP encaps 192.168.1.41 and
192.168.1.64 are 'expected'.
I would expect to see a duplicate chassis entry in the same IP . Who
has this 192.168.1.90 IP ?
A couple of further questions:
- did you upgrade recently your environment ? If so, from which
version to which version ?
- what is the switch type of the cluster where you are running OVN ?
