Hi Team,   I’d like to confirm a requirement related to OpenStack Manila CIFS shares.   When using DHSS=True, is the creation of a Security Service (e.g., Active Directory/LDAP/Kerberos) mandatory for CIFS share provisioning? If it is required, is this mandate defined by OpenStack Manila generally, or is it specific to the NetApp Manila driver?   Any clarification or documentation references would be greatly appreciated. 😊   Thank you! ...

The customer's environment is running RHOSP 16.2.4 with ontap 9.7P16. We upgraded OpenStack to version 17.1.6 using the following command: openstack overcloud upgrade run --stack central --debug --limit allovercloud,undercloud --playbook After the upgrade, while the services started initializing, the process generated an error which caused the cinder volume service to go down.   2025-06-12 11:05:51.025 34 DEBUG cinder.volume.drivers.netapp.dataontap.client.api [req-1c9a7af4-6363-4bf8-a9aa-82cb8e39028c - - - - -] Using NetApp controller: 10.13.10.105 __init__ /usr/lib/python3.9/site-packages/cinder/volume/drivers/netapp/dataontap/client/api.py:84 2025-06-12 11:05:51.026 34 DEBUG cinder.ssh_utils [req-1c9a7af4-6363-4bf8-a9aa-82cb8e39028c - - - - -] Setting strict_ssh_host_key_policy to 'False' using ssh_hosts_key_file '/var/lib/cinder/ssh_known_hosts'. __init__ /usr/lib/python3.9/site-packages/cinder/ssh_utils.py:88 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager [req-1c9a7af4-6363-4bf8-a9aa-82cb8e39028c - - - - -] Failed to initialize driver.: TypeError: argument of type 'NoneType' is not iterable 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager Traceback (most recent call last): 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager File "/usr/lib/python3.9/site-packages/cinder/volume/manager.py", line 481, in _init_host 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager self.driver.do_setup(ctxt) 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager File "/usr/lib/python3.9/site-packages/cinder/volume/volume_utils.py", line 1490, in trace_method_logging_wrapper 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager return f(*args, **kwargs) 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager File "/usr/lib/python3.9/site-packages/cinder/volume/volume_utils.py", line 1490, in trace_method_logging_wrapper 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager return f(*args, **kwargs) 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager File "/usr/lib/python3.9/site-packages/cinder/volume/drivers/netapp/dataontap/nfs_cmode.py", line 89, in do_setup 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager self.zapi_client = dot_utils.get_client_for_backend( 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager File "/usr/lib/python3.9/site-packages/cinder/volume/drivers/netapp/dataontap/utils/utils.py", line 67, in get_client_for_backend 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager client = client_cmode.Client( 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager File "/usr/lib/python3.9/site-packages/cinder/volume/volume_utils.py", line 1490, in trace_method_logging_wrapper 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager return f(*args, **kwargs) 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager File "/usr/lib/python3.9/site-packages/cinder/volume/volume_utils.py", line 1490, in trace_method_logging_wrapper 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager return f(*args, **kwargs) 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager File "/usr/lib/python3.9/site-packages/cinder/volume/drivers/netapp/dataontap/client/client_cmode.py", line 55, in __init__ 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager self._init_features() 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager File "/usr/lib/python3.9/site-packages/cinder/volume/volume_utils.py", line 1490, in trace_method_logging_wrapper 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager return f(*args, **kwargs) 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager File "/usr/lib/python3.9/site-packages/cinder/volume/volume_utils.py", line 1490, in trace_method_logging_wrapper 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager return f(*args, **kwargs) 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager File "/usr/lib/python3.9/site-packages/cinder/volume/drivers/netapp/dataontap/client/client_cmode.py", line 80, in _init_features 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager elif ONTAP_C190 in node['model']: 2025-06-12 11:05:51.150 34 ERROR cinder.volume.manager TypeError: argument of type 'NoneType' is not iterable 1:05:51.150 34 ERROR cinder.volume.manager   below is my question: 1.
