Restarting daemons before db synchronization fails

[Marco CONSONNI]

At the end of http://docs.openstack.org/trunk/openstack-compute/install/content/compute-minimum-configuration-settings.html, the instructions say to restart the daemons.

If you do that before migrating/synchronizing the DB, all the services stop with errors due to tables unavailability.
In fact, the DB has been created in MySQL but it doesn't contain any table and the daemons fail because they look for tables.

Consider the following sequence:

-- Stop all the services with command "sudo stop <serviceName>"
-- Synchronize db with command "sudo nova-manage db sync"
-- Restart all the services with command "sudo start <serviceName>"

Also, check the list of services: nova-cert and nova-consoleauth should be there (I submitted another bug on this matter).

Strange! In my environnment it works.

Well, the sequence described in the document doesn't give any apparent problem but if you examine the daemon's log file, you find out that all the services fail.

This is due to the fact that when they start they try to access tables that are not yet created in MySQL.

As a matter of fact, they are created when you synch the DB.

For this reason, I think that the right sequence is the one I suggested.

Just out of curiosity: what did you do for restarting services?

"service <serviceName> restart" or "service <serviceName> start"?
