a policy statement must specify the compartment for which access is being granted (or the tenancy). Where you create the policy determines who can update the policy. If you attach the policy to the compartment or its parent, you can simply specify the compartment name. If you attach the policy further up the hierarchy, you must specify the path. The format of the path is each compartment name (or OCID) in the path, separated by a colon:
<compartment_level_1>:<compartment_level_2>: . . . <compartment_level_n> For example, assume you have a three-level compartment hierarchy, shown here:

You want to create a policy to allow NetworkAdmins to manage VCNs in CompartmentC. If you want to attach this policy to CompartmentC or to its parent, CompartmentB, write this policy statement:
Allow group NewtworkAdmins to manage virtual-network-family in compartment CompartmentC However, if you want to attach this policy to CompartmentA (so that only administrators of CompartmentA can modify it), write this policy statement that specifies the path:
Allow group NewtworkAdmins to manage virtual-network-family in compartment CompartmentB:CompartmentC To attach this policy to the tenancy, write this policy statement that specifies the path from CompartmentA to CompartmentC:
Allow group NewtworkAdmins to manage virtual-network-family in compartment CompartmentA:CompartmentB:CompartmentC

Explanation
These log files must reside on the boot volume for a minimum of 15 days so you have to increase the boot Volume

Explanation
References:
The terraform plan command is used to create an execution plan. Terraform performs a refresh, unless explicitly disabled, and then determines what actions are necessary to achieve the desired state specified in the configuration files.
This command is a convenient way to check whether the execution plan for a set of changes matches your expectations without making any changes to real resources or to the state. For example, terraform plan might be run before committing a change to version control, to create confidence that it will behave as expected.
