Hi Konstantinos,
One of the things I noticed in the SB DB you attached is that two of the
chassis records have the same hostname:
$ ovn-sbctl list chassis | grep ams03-hypersec02
hostname : ams03-hypersec02
hostname : ams03-hypersec02
This shouldn't be a major issue but shows a potential misconfiguration
on the nodes. Could you please double check the hostname configuration
of the nodes?
Would it also be possible to attach the openvswitch conf.db from the
three nodes? It should be in /var/lib/openvswitch/conf.db
Thanks,
Dumitru
