Hello!

I need to resize (shrink) allocation pool in existing subnets. Change 
has to be done 'on the fly', all subnets in use, with running instances 
on them.

There is existing bug ( https://bugs.launchpad.net/neutron/+bug/1111572 
) which is to be fixed in future, but I need to do this somehow in Grizzly.

I tried to update allocation pool in mysql database, but did not find 
what are needed services to restart?
I restarted quantum-server and quantum-dhcp-agent, but still, new, 
smaller allocation_pool is not honored, but ip's outside pool are used.

Any suggestions how to achieve desired functionality? I assume I should 
restart more services, but I can't figure out what?

Running RedHat RDO packaged grizzly.
