Description of problem:
I already have a cinder volume group (based on LVM), I don't want packstack to create a new one.

Version-Release number of selected component (if applicable):
openstack-packstack-2014.2-0.5.dev1316.g733aa73.el7.centos.noarch

it worked in the past.


cat packst-juno.txt | grep CINDER_VOLUMES
CONFIG_CINDER_VOLUMES_CREATE=n
CONFIG_CINDER_VOLUMES_SIZE=20G

each time, oackstack errors out:
Adding Cinder manifest entries                    [ ERROR ]

ERROR : 'CONFIG_CINDER_VOLUMES_SIZE'
Please check log file /var/tmp/packstack/20141119-094841-pEUQ2V/openstack-setup.log for more information
