[Openstack-operators] Cinder Volume Multi-attach

Hello

I'm running OpenStack Liberty release. 
My question is if cinder supports volume multi-attach ? 
Can the same volume be attached to more than one instances ? 
Should anything be changed in the code level to make it work? 

Currently I was able to create a new volume with --allow-multiattach 
option. 
But it can't be attached to more than one instance. 
I'm getting an error :
"ERROR (BadRequest): Invalid volume: volume 
'08cf47a0-2f31-422b-a124-192155143abf' status must be 'available'. 
Currently in 'in-use' (HTTP 400) (Request-ID: 
req-038db0fa-624d-45a1-a13c-2c5432790019)"

Thank you.
