Public bug reported: AWS provides a scenario to expand volumes of an instance (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-expand-volume.html). It consist of: 1 Stop the instance 2 Create a snapshot of the volume 3 Create a new volume from the snapshot 4 Detach the old volum 5 Attach the new volume using the same device name 6 Start the instance
In Nova this works for non-root devices, but doesn't for a root device. Now in current version (Juno) since https://review.openstack.org/#/c/75552/ was merged it's not able to detach root volume at all. $ nova volume-detach inst 02f60d80-47ee-47ed-a795-cb4d05f5103e ERROR (Forbidden): Can't detach root device volume (HTTP 403) (Request-ID: req-e25134dc-1330-4fe1-9d21-abc274e75a1d) Before this commit it was able, but it was unable to attach the root volume back. ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
