[Openstack-operators] rbd ephemeral storage, very slow deleting...

This is expected behavior, unfortunately.
I spoke to the ceph guys about this last year. When you delete an ‘image’ from a pool, the monitors (IIRC) don’t instantly know where all the segments are across all the OSDs, so it takes a while to find/delete each one.
