Hi,all In the Cinder repository, I noticed that the BlockDeviceDriver driver is being deprecated, and was eventually be removed with the Queens release. https://github.com/openstack/cinder/blob/stable/ocata/cinder/volume/drivers/block_device.py However,I want to use it out of tree,but I don't know how to use it out of tree,Can you share me a doc? Thank you very much! Best Regards Rambo -------------- next part -------------- An HTML attachment was scrubbed...
