Hi, I'm trying to copy a sparse provisioned rbd image from pool A to pool B (both are replicated three times). The image has a disksize of 8 GB and contains around 1.4 GB of data. I do use:
rbd cp PoolA/Image PoolB/Image After copying "ceph -s" tells me that 24 GB diskspace extra is in use. Then I delete the original pool A image and only 8 GB of space is freed. Does Ceph not sparse copy the image using cp? Is there another way to do so? I'm using 0.67.7 dumpling on this cluster.
