Chapter 8. Configure Red Hat Gluster Storage as a Red Hat Virtualization storage domain

8.1. Create the logical network for gluster traffic

  1. Log in to the Administration Portal

    Browse to the Administration Portal (for example, http://engine.example.com/ovirt-engine) and log in using the administrative credentials you configured in Chapter 7, Deploy the Hosted Engine using the Web Console.

  2. Create a logical network for gluster traffic

    1. Click NetworkNetworks and then click New. The New Logical Network wizard appears.
    2. On the General tab of the wizard, provide a Name for the new logical network, and uncheck the VM Network checkbox.
    3. On the Cluster tab of the wizard, uncheck the Required checkbox.
    4. Click OK to create the new logical network.
  3. Enable the new logical network for gluster

    1. Click the NetworkNetworks and select the new logical network.
    2. Click the Clusters subtab and then click Manage Network. The Manage Network dialogue appears.
    3. In the Manage Network dialogue, check the Migration Network and Gluster Network checkboxes.
    4. Click OK to save.
  4. Attach the gluster network to the host

    1. Click ComputeHosts and select the host.
    2. Click the Network Interfaces subtab and then click Setup Host Networks. The Setup Host Networks window opens.
    3. Drag and drop the newly created network to the correct interface.
    4. Ensure that the Verify connectivity between Host and Engine checkbox is checked.
    5. Ensure that the Save network configuration checkbox is checked.
    6. Click OK to save.
  5. Verify the health of the network

    Click the Network Interfaces tab and check the state of the host’s network. If the network interface enters an "Out of sync" state or does not have an IP Address, click ManagementRefresh Capabilities.

8.2. Configure additional hyperconverged hosts

If your environment uses IPv6 addresses, or if you did not specify additional hyperconverged hosts as part of Configure Red Hat Gluster Storage for Hosted Engine using the Web Console, follow these steps in the Administration Portal for each of the other hyperconverged hosts.

  1. Click ComputeHosts and then click New to open the New Host window.
  2. Provide the Name, Hostname, and Password for the host that you want to manage.
  3. Under Advanced Parameters, uncheck the Automatically configure host firewall checkbox, as firewall rules are already configured by the deployment process.
  4. In the Hosted Engine tab of the New Host dialog, set the value of Choose hosted engine deployment action to Deploy. This ensures that the hosted engine can run on the new host.
  5. Click OK.

    1. Attach the gluster network to all remaining hosts
  6. Click the name of the newly added host to go to the host page.
  7. Click the Network Interfaces subtab and then click Setup Host Networks.
  8. Drag and drop the newly created network to the correct interface.
  9. Ensure that the Verify connectivity checkbox is checked.
  10. Ensure that the Save network configuration checkbox is checked.
  11. Click OK to save.

    1. In the General subtab for this host, verify that the value of Hosted Engine HA is Active, with a positive integer as a score.

      Important

      If Score is listed as N/A, you may have forgotten to select the deploy action for Choose hosted engine deployment action. Follow the steps in Reinstalling a hyperconverged host in Maintaining Red Hat Hyperconverged Infrastructure for Virtualization to reinstall the host with the deploy action.

    2. Verify the health of the network

      Click the Network Interfaces tab and check the state of the host’s network. If the network interface enters an "Out of sync" state or does not have an IP Address, click ManagementRefresh Capabilities.
