Hi,

to get the real usage of an image I can run:

rbd diff image1 | awk '{ SUM += $2 } END { print SUM/1024/1024 " MB" }'

To get the cow usage of a snapshot:

rbd diff image1 --from-snap snap1 | awk '{ SUM += $2 } END { print 
SUM/1024/1024 " MB" }'

But I wonder how I can get the cow usage of a clone? I tried passing an 
absolute snapshot name "image1@snap1" but that
doesn't work.

rbd diff clone1 --from-snap image1@snap1 | awk '{ SUM += $2 } END { print 
SUM/1024/1024 " MB" }'
rbd: diff error: (2) No such file or directory

Thanks for any help.

Corin
