The default store for Glance is “file" when not using Ceph.


You can change this by using custom configurations (http://docs.openstack.org/developer/kolla/advanced-configuration.html#openstack-service-configuration-in-kolla).

We support a plugin functionality for our Docker templates.

I think it is better to create the required volume group with a custom Ansible playbook during the bootstrap of your storage node.

> 3. The storage system is HDS AMS2300 which seems do not supported by any Cinder driver. So I have to use LVM backend. According to the cinder/glance bug mentioned in Kolla doc, does it mean that I can not deploy multi-controller scenario, unless using Ceph?

Check if you can use the HDS AMS2300 as external iSCSI storage (http://docs.openstack.org/developer/kolla/cinder-guide.html#cinder-back-end-with-external-iscsi-storage).

I think the use of LVM2 / iSCSI as a layer before the storage backend is not a good idea.
