Open Stack

Hey Carlos,

The work to enable you to do this is in progress.  Kolla needs to refactor the way the Dockerfiles
are templated in order to create additional flexibility.

You can follow the work here: https://blueprints.launchpad.net/kolla/+spec/third-party-plugin-support

Thanks,
Ryan

Subject: [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] 
  default_volume_type = ibm 

  [ibm] 
  volume_driver=cinder.volume.drivers.ibm.storwize_svc.storwize_svc_fc.StorwizeSVCFCDriver 
  san_ip=xxx.xx.xx.xx 
  san_login=superuser 
  san_password=mypass 
  san_ssh_port=22 
  storwize_svc_volpool_name=myPool 
  volume_backend_name=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
