You want something like:
$ rbd ls
NAME SIZE
alpha 50G
beta 400G
charlie 150G
That is possible, but if you want to see the allocation of an image that
will be harder, since RBD doesn't know which objects have been written
to and which haven't.
There is also no such thing as "free pool space", you have to look at
the free cluster space.
But again, if you cluster has X TB of free space and you have multiple
pools, your usage will depend on the amount of written data and the
replication level.
If you want to know the usage of the rbd pool I suggest using "rados df".
The RBD tool could however be modified to show the image size if you
give another flag.
$ rbd --extended ls
