Chapter 12. Configure the logical network for gluster traffic

Procedure

1. Log in to the first hyperconverged host.

2. Change into the hc-ansible-deployment directory:

   # cd /etc/ansible/roles/gluster.ansible/playbooks/hc-ansible-deployment

3. Make a copy of the gluster_network_inventory.yml file for future reference.

   # cp gluster_network_inventory.yml gluster_network_inventory.yml.backup

4. Define your configuration in the gluster_network_inventory.yml file.

   Use the example gluster_network_inventory.yml file to define the details on each host. A complete outline of this file is available in Understanding the gluster_network_inventory.yml file.

5. Encrypt the gluster_network_inventory.yml file and specify a password using ansible-vault.

   The required variables in gluster_network_inventory.yml include password values, so it is important to encrypt the file to protect the password values.

   # ansible-vault encrypt gluster_network_inventory.yml

   Enter and confirm a new vault password when prompted.

Procedure
