Public bug reported: With multiattach now enabled, it should be possible to use the Create Multiple Servers compute api to create multiple instances with a common multiattach disk attached to all of them (assuming you have met all the prerequisites for multiattach to work).
Currently when you try to do a multi-create with a bdm specified (as a non-boot volume), the operation fails with: INFO nova.api.openstack.wsgi [None req-cc49eb29-6fa4-460f-9bda- 45f9c157016f None None] HTTP exception thrown: Cannot attach one or more volumes to multiple instances This is due to a check here: https://github.com/openstack/nova/blob/master/nova/compute/api.py#L731 There may be other issues following this one, but this is the first issue that you run into. version info: nova$ git show commit f25b744082b439b2520f4b3f0549fb074bf522a2 Merge: 980f5c3 a84e7ae Author: Zuul <z...@review.openstack.org> Date: Wed Feb 7 12:24:04 2018 +0000 Merge "Address comments from I51adbbdf13711e463b4d25c2ffd4a3123cd65675" ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
