There is most likely an issue between Cinder and the backend storage device.

You may be able to get some details by using the 'cinder message-list' and
'cinder message-show' command line:

https://docs.openstack.org/python-cinderclient/latest/cli/details.html#cinder-message-list

If that does not provide a reasonable message at least pointing to where the
problem is (which we should probably see if we can improve) then you will
likely need to go to the cinder-volume log files. If you search in there, there
will probably be traceback messages or other errors indicating why the snapshot
failed.
