Currently Glance's Cinder backend driver doesn't support uploading/downloading. Blueprint of current implementation: https://blueprints.launchpad.net/glance/+spec/glance-cinder-driver As missing parts in Cinder listed above (os-brick library, readonly-volumes, multi-attach) are now supported, now we can implement uploading and downloading for it.

Added Gerrit's patch for the implementation
Here's what was discovered during testing of this RFE. It does not appear that this feature has adequate upstream CI testing and the feature is not working even with our attempt to run it with LVM. It was also discovered that it will not work with Ceph behind cinder, but we will document that when the time comes. In addition to the bugs found that this now depends on, Glance is not sending the correct initiator field to cinder during volume connection, and so the attach fails. We will work the dependent bugs first, then see if we can get back to this one, but target is now OSP12 based on priorities.
Paul, Can we escalate development of the fix and then we can figure out if it works, and if we can deliver it earlier in appropriate JS one.
Is this feature available now? See https://bugs.launchpad.net/glance-store/+bug/1382681
Arkady/Ranjini - We are going to circle back on the list of bugs found testing this, the upstream fix was a key issue, but it wasn't the only problem found with the OSP deployment/test. We are tracking this against OSP12 and will follow up soon and will keep the needinfo on me for that.
Initial plan will be to test with LVM for verification of what has landed upstream.
@Eric: Weren't there some other patches you wanted to land to fix this issue?
additional patches/changes are required to make this work and be testable https://review.openstack.org/513202 - puppet-tripleo - stable/pike - merged 2017-11-02 https://review.openstack.org/#/c/516100/ - THT - stable/pike - proposed 2017-11-02 along with openstack-glance-15.0.0-2.el7 cbs build or better (incorporate fix for glance_store rootwrap filter path.) openstack-glance-15.0.0-3.el7ost
Alan, Can you double check comment #40 and external trackers please. I tried to capture the details we were discussing with quick fact check on state of the patches and builds
Added RH Gerrit reviews for rhos-12. Status in comment #40 is correct.
Previous comment was meant to clear needsinfo flag.
The last outstanding patch (backport to Pike) just landed: https://review.openstack.org/#/c/516100/
