Hello, I know that [1] has been something requested by operators before, including myself, but there hasn't been any resources available to perform the work :( Since there is a lot of ways you can get "locked in" when using the RBD image backend with Nova [2]. Best regards [1] https://blueprints.launchpad.net/nova/+spec/nova-ephemeral-cinder [2] Referring to for example Magnum, Octavia etc (For Octavia that is not the case today as they support volume-backed instances now). ________________________________________ From: Radosław Piliszek <radoslaw.piliszek@gmail.com> Sent: Wednesday, April 22, 2020 9:57 AM To: openstack-discuss Subject: Re: [nova] [cinder] [ceph] Questioning deployment choices On Wed, Apr 22, 2020 at 9:32 AM Radosław Piliszek <radoslaw.piliszek@gmail.com> wrote:
Regarding the subject, I also found this: https://blueprints.launchpad.net/nova/+spec/nova-ephemeral-cinder bp: Nova using ephemeral storage with cinder (from 2014-04-30, recurring 2017-04-18; not implemented)

Also, the change referenced by Lee, introducing RBD support into Nova, was part of: https://blueprints.launchpad.net/nova/+spec/bring-rbd-support-libvirt-images... which, based on extensive discussion there, looks like handicapped approach at that other bp. So, essentially, boot-from-volume existed but there was demand for no-Cinder-interactions and Ceph was a popular choice. -yoctozepto
