What is disk.config under /var/lib/nova/instances from newton release?
Under this directory /var/lib/nova/instances following files are present,
disk.config
What exactly this disk.config file do ?
Thanks. If i am not wrong all these informations are already stored in nova db right ? Is there any other specific reason behind using this config file.
They are in the DB, yes. And the config drive is one of two ways for the instance to get the data.
