Open Stack

How can I specify the disk space that instances can occupy in the compute node? Or it will use as much as that of the OS can provide?

In nova-compute.log, it contains some following info:

Hey !
do you have something into the nova-compute.log?

Hi,

I setup an openstack environment with 3 nodes on Ubuntu 12.04 LTS. But I cannot launch instances with disk size bigger than 40GB. It reports the error "NoValidHost". I am sure that there's enough disk size on my compute node.

Could you tell me where I can get more detailed error information or some possible reasons?
