Also Including ceph team Hi Dan, I was following your post of Setting up a Ceph cluster and exporting a RBD volume to a KVM guest. I have few questions, What does mkcepfs do? (A per my understanding from your post ,it is used to to initialize filesystem/object store) How is object store initialized ? (If not the above how does it do) When we trigger mount ,it is like having a file system ? Is it correct to create a rbd device on top of this filesystem.(I am confused about this.)Bock device is something which we have instead of filesystem. Can we create a rbd device without filesystem mounted and can it be a shared device. Please help me.
