When I setup my OS cluster over a year ago, I chose to use
distributed LBaaSv2. That sounded like the most sensible

OS in the first place!
However, it turned out that there’s a very grave bug in
OS - Neutron - (only just recently fixed - a few weeks ago and
only in the latest development code).

I run Newton (and don’t want to risk everything by either
re-installing or upgrading - last time it took me two months
to get things working again!).
Doesn’t seem to be any backport of the fix to Newton :( :(.
Sorry, due to the invasiveness of the changes it won't be backported to
Newton, only Pike will have this support. It also might be slightly
broken until very recent code in stable/pike...
Does anyone have an idea on how I can “hack” the DB
(MySQL) so that it isn’t distributed any more? The OS
command line tools won’t let you de-distribute one :(.
This should be “fairly” straight forward, for anyone that knows
the “inner workings” of Neutron. Simply “undo” whatever
neutron router-create --distributed True --ha False rname
did. I can’t unfortunately delete the router and then recreate
it without destroying my whole setup, instances, networks,
etc, etc. Everything “hangs” off of that router...
I think you should be able to remove the router interfaces on the
external and internal networks then remove the router, without removing
any of the private networks, etc. Then you can create it again with
--distributed=False. VMs might lose connectivity for a bit though.
Ocata supports DVR -> Centralized router migration, so you would only
have to go forward one release if you choose that path.
