Hi,
When we try to add ephemeral disk in booting instance, as we know that
it will create disk.local and the backing file in _/base. Both of them
are referred to the ephemeral disk. When nova reports the disk usage of
compute, does it count both of them for the used disk? What I see in the
resource/_tracker that it calculates the instance[‘ephemeral_gb’].
The resource tracker reports disk usage by adding up the root_gb +
ephemeral_gb values of the *flavor* attribute of the instances assigned
to that compute node.
Does that answer your question?
Best,
