Thanks. I think the only issue with doing snapshots via Cloudstack is potentially having to pause an instance for an extended period of time. I haven’t tested this yet but based on the docs, I think kvm has to be paused regardless.
What about added volumes? Does an instance have to pause of you’re only snapshotting added volumes and not the root disk? Couple of questions. If I snapshot an rbd image from the ceph side, does that require an instance pause and is there a graceful way, perhaps through the api to do the full mapping of instance volumes -> Ceph block image named? So I can understand what block images belong to which Cloudstack instance. I never understood how to properly trace a volume from instance to Ceph image.
