I have a question regarding cinder volume multi-attach function with OpenStack Newton version. In our test, we find it seems the multi-attach works if we attach two VMs to one cinder volume through nova attach command manually, but if we create the cinder volume (with multi-attach flag) and attach it to two VMs through HOT templates, it always report error for the second VM when attaching to the cinder volume. Can anyone share if we can use multi-attach function with HOT templates?
