Now that we have created a block device on a Ceph cluster, in order to use this block device, we need to map it to the client machine. To do this, execute the following commands from the client-node1 machine.
Mapping Ceph Block Device
How to do it...

# rbd map --image rbd1 --name client.rbd

- layering: layering support
- exclusive-lock: exclusive locking support
- object-map: object map support (requires exclusive-lock)
- deep-flatten: snapshot flatten...
