Disk readahead settings

This role can be used to set up modified readahead settings for (virtual machine) block devices.

Requirements

None.

Role Variables

There is one main variable that drives this role: _readahead_setup. It is a map that contains all configuration and settings for this role. Please see defaults/main.yml for details.

Dependencies

None.

Example Playbook

The general contract of this role is to take the variables map _readahead_setup from defaults/main.yml as a template for your configuration and pass that configuration as a parameter to this role.

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: servers
  var:
    readahead_setup:
      ...
  roles:
     - { role: readahead_setup, tags: [ 'readahead_setup' ], _readahead_setup: "{{ readahead_setup }}" }
