Chapter 3. Converting hyperconverged hosts to hyperconverged hosts

Follow this process to convert hyperconverged hosts to hyperconverged hosts. This lets you use and manage the host’s local storage as Red Hat Gluster Storage volumes.

  1. Log in to the Administration Portal.

  2. Move all hosts except the self-hosted engine node into maintenance mode.

    1. Click Compute → Hosts.

    2. For each host except the self-hosted engine node:

      1. Select the host to move to maintenance.
      2. Click Management → Maintenance and click OK.

  3. Enable the gluster service in the cluster.

    1. Click Compute → Clusters and select the cluster.

      The Edit Cluster window appears.

    2. Check the Enable Gluster service checkbox.
    3. Click OK.

  4. Reinstall all hosts except the self-hosted engine node.

    1. Click Compute → Hosts.

    2. For each host except the self-hosted engine node:

      1. Select the host to reinstall.

      2. Click Management → Reinstall and click OK.

        Wait for the reinstall to complete and for the hosts to become active again.

  5. Move the self-hosted engine node into maintenance mode.

    1. Select the self-hosted engine node.

    2. Click Management → Maintenance and click OK

      The hosted engine migrates to one of the other hyperconverged hosts.

  6. Reinstall the previous self-hosted engine node.

    1. Select the previous self-hosted engine node.

    2. Click Management → Reinstall and click OK.

      Wait for the reinstall to complete and for the host to become active again.

Your hosts are now able to use and manage storage as Red Hat Gluster Storage volumes.
