flavor disk size too small to deploy overcloud #8

Closed judge-red closed 8 years ago

judge-red commented 8 years ago

Following the instructions at: https://www.rdoproject.org/testday/mitaka/milestone3/ https://www.rdoproject.org/rdo-manager/ http://docs.openstack.org/developer/tripleo-docs/basic_deployment/basic_deployment_cli.html#upload-images (on CentOS 7, without any special configuration), the overcloud deployment will fail when executing openstack overcloud deploy --templates.

The error given was:

And in /var/log/nova/nova-scheduler.log:

So the disks should be (slightly) bigger.
