Comment 4 for bug 1009546

Totally agree with what Dan said, db sync is not expected to be executed on more than one server ,it is an admin action. As nova is in development. so it is only necessory when db schema changes . whether or not upgrade the db schema is controlled by OpenStack Cloud system admin. also, the blueprint no-db-compute is trying to removing direct accessing db for nova-compute .

the problem above is a system management issue more than a project code bug.
