[Bug 1922934] [NEW] [OVN] LSP register race condition with two controllers
Public bug reported:
A race condition between two Neutron controller happened during the
creation and the binding of a port. This problem happened when one
Neutron controller received the port creation command. The controller
added this new LSP to the OVN database.
But the second controller does not receive the OVN database update and
does not update the local database cache (in the IDL instance). That
means, one second after the port creation done in the first controller,
the second controller does not find the LSP.
Nova error: http://paste.openstack.org/show/804261/
First Neutron controller adding the port: http://paste.openstack.org/show/804262/
Second Neutron controller failing to find the port: http://paste.openstack.org/show/804263/
As seen in the logs, the second controller did not receive the
transaction update adding the LSP.
