1, delete the original volumes.
vgremove cinder-volumes (when installed packstack OpenStack, created on the original system disk SDA, relatively small)
2, create pv.
pvcreate / dev / sdxx #sdxx to be prepared as a cinder back-end storage drives, such as SDC ..... sdb
3, create vgcreate cinder-volumes / dev / sdxx , ( the default name, you can customize, but needs the configuration files of cinder-volumes into your custom name)
when ※ cinder-volumes of packstack installation openstack, generated volume group name.
4, restart the associated service.
systemctl restart openstack-cinder-volume # lvm.conf need to modify the operation.
