25.8. Configuring a stripe size for RAID LVM volumes by using the storage RHEL system role

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: Configure stripe size for RAID LVM volumes
         ansible.builtin.include_role:
           name: redhat.rhel_system_roles.storage
         vars:
           storage_safe_mode: false
           storage_pools:
             - name: my_pool
               type: lvm
               disks: [sdh, sdi]
               volumes:
                 - name: my_volume
                   size: "1 GiB"
                   mount_point: "/mnt/app/shared"
                   fs_type: xfs
                   raid_level: raid0
                   raid_stripe_size: "256 KiB"
                   state: present

   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.

   注記

   Setting raid_level at the volumes level creates LVM RAID logical volumes.

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
