devstack kilo version of OpenStack and created an instance on it with
flavor <b>“m1.nano”</b> that gives a disk of 0 to your instance.
</p><p style="margin-bottom: 0cm; line-height: 100%">But while checking
disk usage of the instance using <b>“disk.usage”</b> meter it
gives the output to be greater than 0 so how is it possible ?
