Hello all. The current behavior of snapshotting instances RBD-backed in OpenStack involves uploading the snapshot into Glance. The resulting Glance image is fully allocated, causing an explosion of originally sparse RAW images. Is there a way to preserve the sparseness? Else I can use qemu-img convert (or rbd export/import) to manually sparsify it? On a related note, my Glance is also backed by the same Ceph cluster, in another pool and I was wondering if Ceph snapshots would not be a better way to do this. Any ideas?
