Description RHOS Integration 2014-01-22 05:03:49 UTC
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/libvirt-resize-disk-down.

Description:

The actual implementation of libvirt for openstack does not resize the disk down during a scale down of an instance that needs a disk resize. Then the actual implementation just skip this step silently. (https://review.openstack.org/#/c/67430/)

    We need to add this feature to the driver libvirt.

There is a discuss on: https://bugs.launchpad.net/nova/+bug/1270238

"""About the risk of the implementation, in the workflow of a resize, every modifications on the disk are doing in a copy. The user is asked to check if all run well: during this step the user can check the console-log and connect itself on the instance to check if all is OK.
    if all is ok he just have to confirm the resize (resize-confirm).
    if something wrong he can do a revert (resize-revert)

The implementation of xenapi seems to support this feature. For vmware, it is not implemented yet (only extend)."""
