Hello Jason/Kees, I am trying to take snapshot of my instance.
Image was stuck up in Queued state and instance is stuck up in Image Pending Upload state. I had to manually quit the job as it was not working since last 1 hour .. my instance is still in Image Pending Upload state. Is it something wrong with my ceph configuration? can i take snapshots with ceph storage? How?
