Resizing Openstack VM's Volumes

Problem:

1. to resize the volume, the volume must be detached first.
2. but if it is the only boot volume, or the vm is created by the volume, it cannot be detached.

Solution (after shutdown the VM):

1. Login . ~/keystone_admin
2. Check volume ID, VM ID by cinder list or openstack volume list, for ex.

VOLUME=ce6e79c1-5b57-49aa-9a66-acf17f37be70
