Re: [openstack-dev] [Cinder] Tags for volumes

You can deploy Searchlight (https://wiki.openstack.org/wiki/Searchlight) and it can handle this and more complex metadata querying (it is backed by elastic search and supports all of the expressive power of elastic search queries). There's a limit to how much query functionality can go into a

[openstack-dev] [Cinder] Tags for volumes

Hi cinder team: I want to know what's your thought about adding tags for volumes. Now Many resources, like Nova instances, Glance images, Neutron networks and so on, all support tagging. And some of our cloud customers want this feature in Cinder as well. It's useful for auditing,
