Summary
Currently the Block Storage (Cinder) service only allow a volume to be attached to one instance at a time. The Compute Service (Nova) also makes assumptions in a number of places to this effect as do the APIs, CLIs, and UIs exposed to users. This specification is drafted in support of multi-attach-volume and aims to outline the changes required to allow users to share volumes between multiple guests using either read-write or read-only attachments.
Comments from a previous proposal to this effect (shared-volume) were also taken into consideration. Further background is also available in the etherpad from the relevant session at the Portland (Havana) Design Summit.
