John, Sorry I misread what you were trying to do. I thought you wanted to create a new instance with the snapshot not revert to it. I've included the link for how to revert volumes. https://docs.openstack.org/cinder/pike/admin/blockstorage-volume-backups.htm... I'm also forwarding this email to the OpenStack Discuss list which is the appropriate list for dev and ops issues. Thanks, Amy (spotz) On Tue, Dec 3, 2019 at 9:29 AM Ratliff, John <jdratlif@iu.edu> wrote:

Thanks, but that feels like a really complicated process to rollback. It seems I would need to delete my old machine and volume, make a volume from the snapshot, create a new one with the same port, a new volume and specify the cloud-init script.

Is that really the best way to revert to a snapshot? I don’t have a lot of experience with openstack, and the documentation and scope is quite large, but I’ve used vmware, libvirt with qemu, hyper-v, and virtualbox, and they all had a fairly simple one-step process to revert a snapshot. I feel like I’m missing something easy.

Thanks.

You should be able to create a new instance using that snapshot as the image.

I am trying to create an instance that I can revert to a snapshot. I created the snapshot with openstack volume snapshot create, but I don’t see a way to revert the instance to that image.

What can I do to make use of the snapshot?

Thanks.
