Environment

  • Red Hat OpenStack Platform
  • openstack-cinder LVM backend
  • no block device used for the cinder-volume group to manage the volumes

Note The default LVM cinder backend is NOT recommended for production usage as it lacks high availability features and has significant performance issues.
