Issue with Volume snapshot create

[Deepa]

When I try to run below command

openstack volume snapshot create --force --description "`date`" bfe272e1-f696-4b18-ba0c-c8e61334b92c
unorderable types: int() > NoneType() <<<<<< getting this error

bfe272e1-f696-4b18-ba0c-c8e61334b92c volume is in use and hence trying to forcefully.
Even same error with available luns .

We have a setup of 3 controller,6 hypervisor running ubunutu 16.04 with Ocata Openstack in it.

IMO, it is an issue in cinder, not nova.
But the version information of the following openstack components should be added in this report.

* cinder
* python-openstackclient
(* nova)

[Deepa (dpaclt)]

Please find the version details below

* cinder
1.11.0

* python-openstackclient-

openstack 3.9.0

(* nova)

7.1.0

Please let us know if any more further information needed.
