Open Stack

Hi list,

I have a question regarding high availability.
There's an existing cloud (Ocata) which developed from demo to  
production environment. Now I have to find a way to make it highly  
available, starting with the control node. I've been gathering all  
kinds of information to prepare a migration.

The plan is to leave the existing single-controller up and running  
while I configure two new servers in HA mode with Pike release in the  
meantime. There are two main aspects causing some headaches: database  
and networking. I believe the database part could be tricky but  
manageable, stop mysql at some point and dump the DB, then import it  
to the new control node(s) (maybe on shared storage) and hope that it  
works.

But what about neutron and the self-service networks with all the  
virtual routers etc.? Is it even possible to recreate the neutron  
environment on a different node? I read the guide on how to make  
neutron ha if you start from scratch, but is my approach realisticly  
possible?

I would really appreciate any insights from you guys. Is there maybe  
someone who has done this and could comment my approach?

Regards,
Eugen
