Thanks Wido.
So it seems there is no way to do this under Hammer.
Not very easily no. You'd have to count and stat all objects for a RBD
image to figure this out.
For hammer you'd need another loop and sum around this:

Hi,
Is there any way to check the block device space usage under the
specified pool? I need to know the capacity usage. If the block device
is used over 80%, I will send an alert to user.
This can be done in Infernalis / Jewel, but it requires new RBD features.
It needs the fast-diffv2 feature iirc.
Thanks a lot!
Best Regards,
WD
