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

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,
