Will this affect detaching/attaching of root volume (https://review.openstack.org/#/c/340874/2/specs/ocata/approved/detach-boot-volume.rst)? I do not know if and how the spec is implemented, but it says: --- The usual attach volume API call will be used to attach the boot volume. The volume attach operation allows a user to specify the name of the device. The boot device name of an instance is known so that is used to determine that the user is attempting to attach the volume as the root device. --- -------------- next part -------------- An HTML attachment was scrubbed...
