[openstack-dev] [kolla] Cinder multiple backends

Hi folks, 

It seems that Kolla does nos provide option to enable multiple backends in Cinder config. 

Currently in my deploy/setup I needed enable the Storwize Cinder driver - http://docs.openstack.org/mitaka/config-reference/block-storage/drivers/ibm-storwize-svc-driver.html - 
and to this I added into /etc/kolla/config/cinder.conf my configs 

  default_volume_type = ibm 

  verbose = True 
  debug = True 

And I changed manually the file /var/src/kolla-master/ansible/roles/cinder/templates/cinder.conf.j2 as well. 

But for the driver works correctly, it was needed install manually some aditional packs. 

$ apt-get install sysfsutils sg3-utils on cinder-volume container 
$ apt-get install multipath-tools sysfsutils on nova-compute container

Is there any doc/spec to create a automatic process for this ? Could someone give us details how is the best way to make it "automatized" !? 

Best regards, 

- Carlos
