Creating a volume is not the same as creating a volume type. A tenant can consume a volume type that allows multi-attach with no issue as you see in that policy. ________________________________ From: Albert Braden <ozzzo at yahoo.com> Sent: 22 February 2023 17:12 To: Openstack-discuss <openstack-discuss at lists.openstack.org> Subject: [kolla] [train] [cinder] Volume multiattach exposed to non-admin users via API CAUTION: This email originates from outside THG According to this document [1] multiattach volumes can only be setup if explicitly allowed by creating a “multiattach” volume type. “Starting from the Queens release the ability to attach a volume to multiple hosts/servers requires that the volume is of a special type that includes an extra-spec capability setting of multiattach=<is> True… Creating a new volume type is an admin-only operation by default. One of our customers appears to have used TerraForm to create a volume with the multiattach flag set and it worked, and that volume has multiple attachments. When I look here [2] it appears that the default is: #"volume:multiattach": "rule:xena_system_admin_or_project_member" So it looks like, by default, any project member can create a multiattach volume. What am I missing?
