[HA] TripleO should support Node replacement of OpenDaylight controller
Last modified: 2018-02-05 14:10:03 EST
Description of problem:
There is a procedure to replace an OpenStack controller node but not one for
TripleO should support this case.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Itzik, have you discussed this with Tim? Is there an upstream bug for this?
No,I'll discuss it with him.
The document for Node replacement:
After reading the instructions I believe that this method with OpenDaylight as a service on the controller should just work. ODL is not managed by pacemaker and does not rely on the other services that require manual intervention. The puppet-opendaylight module should fix the config files to use the new node as part of the cluster and restart all ODLs during the update. That means there is likely < 5 min of downtime for ODL during the operation, but dataplane should remain up.
