Hi Folks,

The work has been ongoing for a while now to implement the feature to support 
attaching a single volume to multiple VM instances.

This work impacts both Nova and Cinder. We are in quite good shape with the 
implementation, but it is still far for completion and we temporarily ran out 
of resources and looking for hands to help out. We have the following items 
left:

* Cinder
  * Blueprint implementation finished on server and client side too
  * Volume detach has a bug, which makes the feature unusable at the moment. A 
proposed fix is up for review, but we couldn't reach a consensus yet regarding 
solution: https://review.openstack.org/#/c/198400/ 

* Nova
  * Spec is re-proposed for Mitaka
    * https://review.openstack.org/#/c/212508/ 
    * Encryption needs to be sorted out
  * Code for Nova side is up for review
    * 
https://review.openstack.org/#/q/status:open+project:openstack/nova+branch:master+topic:bp/volume-multi-attach,n,z
    * REST API is not finished
    * Needs rebase and code review

* Testing
  * Tempest coverage is missing
  * Manual/functional testing is missing

There will be a Nova - Cinder cross project session during the Summit, which 
can be a good opportunity to discuss the missing pieces and identified issues: 
https://mitakadesignsummit.sched.org/event/eb6adc828485d7bce0cba6654cc33156#.VifQYZeLJ4M
 

If you are interested in this feature, we could use some help in clarifying the 
encryption in the spec, fixing the Cinder bug, finish the Nova patches or 
adding Tempest coverage. If you would like to jump in and start with any tasks, 
please let me know. If you will be in Tokyo next week we can either meet on the 
session I linked above or we can set up a meeting separately to discuss how to 
move forward, otherwise we can discuss next steps in either mail or IRC.

Thanks and Best Regards,
Ildikó
