Description of problem:
Used below DV to clone a volume from cephfs to ceph-rbd storage class:
apiVersion: cdi.kubevirt.io/v1beta1 kind: DataVolume metadata: name: rhel8-imperial-sailfish-clone spec: source: pvc: name: "rhel8-imperial-sailfish" storageClassName: ocs-external-storagecluster-cephfs namespace: nijin-cnv storage: resources: requests: storage: 33Gi storageClassName: ocs-external-storagecluster-ceph-rbd
The cloning looks to be successful:
I1221 15:46:44.535710 1 uploadserver.go:74] Running server on 0.0.0.0:8443
I1221 15:46:54.795381 1 uploadserver.go:389] Content type header is "filesystem-clone"
I1221 15:48:23.381155 1 uploadserver.go:416] Wrote data to /dev/cdi-block-volume
I1221 15:48:23.381241 1 uploadserver.go:203] Shutting down http server after successful upload
I1221 15:48:23.381665 1 uploadserver.go:103] UploadServer successfully exited
But there is nothing in the cloned volume and it's all zeroes.
