As far as I know, there's no way to guarantee, that you can't find anything on the OSD's block device. But when you delete snapshots and remove the rbd, it would be
awful trying to reconstruct anything.

Hi list,

just a quick question: is there a way to securely (cryptographicly) erase 
images in Ceph?
Overwriting / shredding the VM's block device from a live ISO is probably not 
enough given that Ceph
might use Copy on Write. So does Ceph provide something alike?
