Comment 4 for bug 1414432

Hi Mark,
I think 'local_gb' should be interpreted as the available storage space seen by each compute node, that makes sense for scheduling, nova-client doesn'st add up 'local_gb' , but Nova add up 'local_gb' see
https://github.com/openstack/nova/blob/master/nova/db/sqlalchemy/api.py#L648
so we need change Nova code :-)

More thougts:

 Do we support some compute nodes with shared_storage, and others doesn't in one OpenStack development ?
 If yes, we face more complicated case, maybe we need admin point out the deployment and pass the information
to Nova.
