5.2. Removing a Host from a Self-Hosted Engine Environment

To remove a self-hosted engine node from your environment, place the node into maintenance mode, undeploy the node, and optionally remove it. The node can be managed as a regular host after the HA services have been stopped, and the self-hosted engine configuration files have been removed.

Procedure 5.3. Removing a Host from a Self-Hosted Engine Environment

  1. In the Administration Portal, click the Hosts tab. Select the self-hosted engine node and click Maintenance to set it to the local maintenance mode.
  2. Click Edit.
  3. Click the Hosted Engine sub-tab and select the Undeploy radio button. This action stops the ovirt-ha-agent and ovirt-ha-broker services and removes the self-hosted engine configuration file.

    Note

    The host will be visible, but shown as unavailable when running hosted-engine --vm-status. This is because the metadata is not removed when a host is undeployed. The removed host will disappear in approximately a week when the metadata is not refreshed. To force the removal of the host's metadata follow the procedure in How to clean the metadata of redeployed Hosts in a Hosted Engine setup.
  4. Optionally, click Remove to open the Remove Host(s) confirmation window, and click OK.
