Creating Ceph Block Device

Up to now, we have configured Ceph client, and now we will demonstrate creating a Ceph Block Device from the client-node1 machine.

How to do it...

1. Create a RADOS Block Device named rbd1 of size 10240 MB:

        # rbd create rbd1 --size 10240 --name client.rbd

2. There are multiple options that you can use to list RBD images:

        ## The default pool to store block device images is "rbd",
           you can also specify the pool name with the rbd 
           command using -p option:
        # rbd ls --name client.rbd
        # rbd ls -p rbd --name client.rbd
        # rbd list --name client.rbd

3. Check the details of the RBD image:

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