Hi, i am running a Ceph cluster that contains the following RBD image: root at ceph0:~# rbd info -p cephstorage debian_6_0_9_template_system rbd image 'debian_6_0_9_template_system': size 30720 MB in 7680 objects order 22 (4096 kB objects) block_name_prefix: rbd_data.1907c2ae8944a format: 2 features: layering, striping stripe unit: 4096 kB stripe count: 1 If I make a flattened clone of the image (create a snapshot - protect the snapshot - clone - flatten the clone) the output of rbd image is: root at ceph0:~# rbd info -p cephstorage debian_6_0_9_system rbd image 'debian_6_0_9_system': size 30720 MB in 7680 objects order 22 (4096 kB objects) block_name_prefix: rbd_data.199bc2eb141f2 format: 2 features: layering Why is the striping feature missing in the clone? Is there a way to enable it on the cloned image? Does it even matter? Best Gerhard
