Hi All, We are trying to test DataCore storage backend for cinder ( running on Queens ). We have everything installed and have the cinder config all setup. However whenever we try and start the "cinder-volume" service, we get the following error: 2019-07-11 12:30:06.977 1909533 ERROR cinder.volume.manager File "/openstack/venvs/cinder-17.1.2/lib/python2.7/site-packages/cinder/volume/manager.py", line 456, in init_host 2019-07-11 12:30:06.977 1909533 ERROR cinder.volume.manager self.driver.do_setup(ctxt) 2019-07-11 12:30:06.977 1909533 ERROR cinder.volume.manager File "/openstack/venvs/cinder-17.1.2/lib/python2.7/site-packages/cinder/volume/drivers/datacore/iscsi.py", line 83, in do_setup 2019-07-11 12:30:06.977 1909533 ERROR cinder.volume.manager super(ISCSIVolumeDriver, self).do_setup(context) 2019-07-11 12:30:06.977 1909533 ERROR cinder.volume.manager File "/openstack/venvs/cinder-17.1.2/lib/python2.7/site-packages/cinder/volume/drivers/datacore/driver.py", line 116, in do_setup 2019-07-11 12:30:06.977 1909533 ERROR cinder.volume.manager self.configuration.datacore_api_timeout) 2019-07-11 12:30:06.977 1909533 ERROR cinder.volume.manager File "/openstack/venvs/cinder-17.1.2/lib/python2.7/site-packages/cinder/volume/drivers/datacore/api.py", line 176, in __init__ 2019-07-11 12:30:06.977 1909533 ERROR cinder.volume.manager raise datacore_exceptions.DataCoreException(msg) 2019-07-11 12:30:06.977 1909533 ERROR cinder.volume.manager DataCoreException: Failed to import websocket-client python module. Please, ensure the module is installed. We have the "websocket-client" installed also: pip freeze | grep websocket websocket-client==0.44.0 The datacore libraries also appear to be available in our venvs dirs: ls /openstack/venvs/cinder-17.1.2/lib/python2.7/site-packages/cinder/volume/drivers/datacore api.py driver.py exception.py fc.py __init__.py iscsi.py passwd.py utils.py We are a bit stumped at the moment and wondered if anyone knew what might be causing the error? We have managed to get Ceph and SolidFire working fine. Regards, -- Grant Morley Cloud Lead, Civo Ltd www.civo.com <https://www.civo.com/>| Signup for an account! <https://www.civo.com/signup>
