kolla-ansible precheck LVM volume group failed

[Jiao Peng]

I deploy a kolla environment, when i executed the command `kolla-ansible prechecks -i /usr/share/kolla/ansible/inventory/multinode`, the console show the error as follow:
=====
TASK [prechecks : Checking LVM volume group exists for Cinder] *****************
fatal: [local_node1]: FAILED! => {"failed": true, "msg": "'cinder_volume_group' is undefined"}
=====
I find the reason is the variable is undefined in the prechecks role and group_vars/all.yml

hope it can help you,and in you can set cinder_volume_group in /etc/kolla/globals.yml

edit the group_vars/all.yml, add the code `cinder_volume_group: "cinder-volumes" ` to repaire the bug

[Jiao Peng (greedywolf)]

i find in the newest code, the file kolla/etc/kolla/globals.yml have the variable "cinder_volume_group", just the variable is annotated, if we want to use cinder, we must make the variable enable

[Jeffrey Zhang (jeffrey4l)]

We have `cincer_volume_group` variable in cinder's role

# ack-grep cinder_volume_group
ansible/roles/cinder/defaults/main.yml
80:cinder_volume_group: "cinder-volumes"

But is is used in pre-check. Please move this variable into group_vars/all.yml file.

    precheck fails due to unknown cinder_volume_group

    cinder_volume_group property is not seen by precheck tasks -
    moving it to common group variables.
