Hi all,

I only want to resize just the disk space with root_gb or ephemeral_gb.
if I run a "nova resize" command to change the disk space of a instance,
and leave the vcpu and memory untouched,
I'll get the error message like this :
ERROR: Resize requires a change in size. (HTTP 400)
The condition of the resize procedure seems must be a change with memory
(vcpu is not must be ).
Is there any nova config option to do with this?

Thanks,
-Jimmy
