It’s been a while, but now I’m there again!

Dumbasses in the shop downstairs was playing with the power
lines, so all power in my apartment died as well :(.


I’ve taken up my two primaries (Nova, Neutron, Cinder etc masters)
but only one “comes up”. The second primary refuses to change to
“UP”.

What database and table is that column located in? And why won’t
the second primarys services come up?!


I’ve checked the RabbitMQ and MySQL cluster - all ok as far as I can
tell.

I’ve restarted all Nova, Neutron and Cinder services on the secondary
master but can’t see anything. The logs looks all ok but the services are
still listed as “DOWN”.
