Description Dumitru Ceara 2019-12-03 11:00:42 UTC
+++ This bug was initially created as a clone of Bug #1779121 +++

Description of problem:
In case the incremental processing code in ovn-controller hits a bug and the state is inconsistent there's no way to trigger a full recompute that would properly install all flows.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. ovn-appctl -t ovn-controller recompute
2.
3.

Actual results:
Command doesn't exist.

Expected results:
The command should run and force a full recompute in ovn-controller.
