Since Ceph version Infernalis (9.2.0) the new fast-diff mechanism of RBD allows for querying actual volume usage. Prior to this version there was no easy and fast way to query how much allocation a RBD volume had inside a Ceph cluster. To use the fast-diff feature it needs to be enabled per RBD image and is only supported by Ceph cluster running version Infernalis (9.2.0) or newer. Without the fast-diff feature enabled libvirt will report an allocation identical to the image capacity. This is how libvirt behaves currently. 'virsh vol-info rbd/image2' might output for example: Name: image2 Type: network Capacity: 1,00 GiB Allocation: 124,00 MiB Newly created volumes will have the fast-diff feature enabled if the backing Ceph cluster supports it.
