 **8. Extend Volume (Grow)**
+Volumes can also be extended in size. In order to Extend the volume it must be unmounted and detached from an Instance.
+     Note: Volumes cannot have their size reduced.

+Enter the new size of the volume and click **Extend Volume**.
+Re-attach the volume to your Instance, and remount the volume from within the instance. You will need to grow the xfs filesystem before it will make the new space available.

+**How to deploy windows on openstack**
+Windows Image for OpenStack: For most Linux distributions, it is possible to download a generic QCOW2 file for the purposes of running instances in a cloud environment. However, Microsoft does not provide such instances for any Cloud platform other than Azure.
+Since Microsoft Windows is still a major component in many IT infrastructures, there may be a need to run Windows-based instances on OpenStack.
+To upload Windows image, We suggest that you follow this tutorial for [[https://superuser.openstack.org/articles/how-to-deploy-windows-on-openstack/|Preparing windows images]] before uploading to the openstack environment.
+       Note: CHPC does not provide licenses, Appropriate licenses for any software run on the service by
+       users must be sought and applied by the users, including any licenses that may be required to run
+       instance operating systems.
