To Reproduce

Use nimble cinder driver

Expected behavior

• creates cinder volume with thin provisioning 

Bug impact

• Volumes are created as thin on the backend 
• But cinder reports backend does not support thin provisioning 
• Causes scheduler to fail once allocated volume reach a 100%
• While there is minimal actually disk usage  

Known workaround

• disable the CapacityFilter in the cinder scheduler_default_filters

Additional context

• https://github.com/openstack/cinder/commit/ed5012a22ee5013162850867ceb4ec707d38596e
• Upstream I believe this is the change in the driver that would solve the issue
• Customer affected is opening a bug with there storage support to try and get the driver fixed
• This bug is just to request that the driver is backported into 16.2, 17.1 and 18.0 if possible if the upstream code is fixed
