Chapter 2. Creating a Block Device Image

Before you can add a block device to a node, you must create an image for it in the Ceph Storage Cluster first. To create a block device image, execute the following:

rbd create {image-name} --size {megabytes} --pool {pool-name}

For example, to create a 1GB image named foo that stores information in a pool named swimmingpool, execute the following:

rbd create foo --size 1024
rbd create bar --size 1024 --pool swimmingpool
