Re: BOSH multi-zone resurrector

John Wong

Hi also interested in this topic.

Is there a plan to be able to fallback to other zones? This seems like a
good capacity management but from automated recovery this seems like chore.
What do you suggest?

Currently Director will bring back VMs in the same AZ as configured in the
manifest because resource pool is configured to point to that specific AZ.

If Director is in the affected zone you will have to redeploy Director to
a different AZ and restore DB from a backup or point to external DB that it
was using.

I have a question about resurrection algorithm BOSH uses in multi zone
deployment. Suppose we have three availability zones: z1, z2 and z3. We
data/0 vm in z1 with resurrection enabled.

Suppose now that z1 goes down.

Will resurrector start new data/0 instance in another zone? If yes, how
it chose between z2 and z3?

What if BOSH director itself is deployed to the z1?
