3. Edit the ansible.cfg file and add the following lines:

   [defaults]
   inventory = ./inventory/staging # Assign a default inventory directory

4. Create an inventory 'hosts' file for each environment:

   [ansible@admin ceph-ansible]$ touch inventory/staging/hosts
   [ansible@admin ceph-ansible]$ touch inventory/production/hosts

   1. Open and edit each hosts file and add the Ceph Monitor nodes under the [mons] section:

      Copy to Clipboard Toggle word wrap

      [mons]
      MONITOR_NODE_NAME_1
      MONITOR_NODE_NAME_1
      MONITOR_NODE_NAME_1

      Example

      Copy to Clipboard Toggle word wrap

      [mons]
      mon-stage-node1
      mon-stage-node2
      mon-stage-node3

      Note
