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.

Hi, guys I have a silly question. As I far I know cinder is working ok with netapp nfs. For balance reasons I have created a several nfs volumes each per controller. But I can not select a individual volume in order to create a openstack volumes. Every time that I create a openstack Volume, Openstack use the same netapp NFS volume. BTW vol1 var/lib/cinder/mnt/284ed7dd9710fcad3e61e80b246f1393 is W/R ok.     ------------------------------------------------------------------------------------------------------------- Netapp vol connected to nova Controller [root@compute0 ~]#df Filesystem 1K-blocks Used Available Use% Mounted on devtmpfs 8033776 0 8033776 0% /dev tmpfs 8054320 4 8054316 1% /dev/shm tmpfs 3221728 361716 2860012 12% /run /dev/mapper/cs-root 43249016 4917396 38331620 12% / /dev/mapper/cs-home 21112760 180668 20932092 1% /home /dev/sda2 1038336 221732 816604 22% /boot /dev/sda1 613160 7708 605452 2% /boot/efi /dev/loop0 1894248 164 1772844 1% /srv/node/swiftloopback tmpfs 1610864 4 1610860 1% /run/user/0 10.10.60.249:/openstack_vol1 498073600 29568 498044032 1% /var/lib/cinder/mnt/284ed7dd9710fcad3e61e80b246f1393 10.10.60.250:/openstack_vol2 597688320 1280 597687040 1% /var/lib/cinder/mnt/f4fc96422bb5f07003ce1a8763033a1d ------------------------------------------------------------------------------------------------------------- cat /etc/cinder/shares.conf 10.10.60.249:/openstack_vol1 10.10.60.250:/openstack_vol2 ------------------------------------------------------------------------------------------------------------- No openstack volumes.
