os_brick.exception.InvalidParameterValue: nfs_mount_point_base required

[Francois Michaut]

On Ubuntu 20.04, I installed cinder with only NFS backend, and zun.
(Followed Openstack Xena installation)

I have an existing cinder volume that I want to attach to my container.
When I do so, the container fails to create and zun-compute report an exception (attached log).

I investigated a bit, and 'os_brick/remotefs/remotefs.py' expect to find a 'mount_point_base' key in kwargs, but kwargs only contains {'use_multipath': False}.

We can see in the log that the 'mount_point_base' is present when the CinderWorkflow class is processing the request, but it doesn't pass this parameter when it creates the following classes.

This is a quick patch for this issue that I am currently using in my setup

I have same issue, but in kolla-ansible. There isnt possible use of the quick patch because images are downloaded from the hub.
