Not sure if this is a good/valid question.
I have deployed a lot of VMs in a ceph cluster that were cloned from an
original rbd image.
I want to see how much of the original image is a new VM (cloned image)
using. Is there any command to get such details?
$ rbd info cvm/f6d058e73ab4a0e1262b3140731b4980-1
rbd image 'f6d058e73ab4a0e1262b3140731b4980-1':
size 61440 MB in 15360 objects
