第 25 章 Managing local storage by using RHEL system roles

Procedure

1. Create a playbook file, for example, ~/playbook.yml, with the following content:

   ---
   - name: Manage local storage
     hosts: managed-node-01.example.com
     tasks:
       - name: Create an XFS file system on a block device
         ansible.builtin.include_role:
           name: redhat.rhel_system_roles.storage
         vars:
           storage_volumes:
             - name: barefs
               type: disk
               disks:
                 - sdb
               fs_type: xfs

   The settings specified in the example playbook include the following:

   name: barefs

   The volume name (barefs in the example) is currently arbitrary. The storage role identifies the volume by the disk device listed under the disks attribute.

   fs_type: <file_system>

   You can omit the fs_type parameter if you want to use the default file system XFS.

   disks: <list_of_disks_and_volumes>

   A YAML list of disk and LV names.

   For details about all variables used in the playbook, see the /usr/share/ansible/roles/rhel-system-roles.storage/README.md file on the control node.

2. Validate the playbook syntax:

   $ ansible-playbook --syntax-check ~/playbook.yml

   Note that this command only validates the syntax and does not protect against a wrong but valid configuration.

3. Run the playbook:

   $ ansible-playbook ~/playbook.yml
