Hi @Michal Arbet,

I think there may be some confusion, this was just a working example for @garcetto.  So no question 😄

Hi,

Okay, this is correct approach ... So I am not sure what you are actually asking .. What is not working ...

The way we do it is using an override for the cinder-volume.conf:

$ cat cinder-volume.conf

[DEFAULT]

enabled_backends=pure-az1,pure-az2

debug = True

cross_az_attach = False

[pure-az1]

volume_driver = cinder.volume.drivers.pure.PureISCSIDriver

san_ip = {{ pure_az1_vip }}

pure_api_token = {{ pure_az1_token }}

volume_backend_name = high-performance

report_discard_supported = True

suppress_requests_ssl_warnings = True

backend_availability_zone = {{ availability_zone_1 }}

backend_host = pure

[pure-az2]

volume_driver = cinder.volume.drivers.pure.PureISCSIDriver

san_ip = {{ pure_az2_vip }}

pure_api_token = {{ pure_az2_token }}

volume_backend_name = high-performance

report_discard_supported = True

suppress_requests_ssl_warnings = True

backend_availability_zone = {{ availability_zone_2 }}

backend_host = pure

With multiple ceph clusters it becomes slightly more complicated unless you are running the bobcat version of kolla-ansible because that is the first release that officially supports disparate ceph backends:  https://github.com/openstack/kolla-ansible/blob/stable/2023.2/ansible/roles/cinder/tasks/external_ceph.yml#L19
