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
- 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.
- Click Edit.
- Click the Hosted Engine sub-tab and select the Undeploy radio button. This action stops the
ovirt-ha-agent
andovirt-ha-broker
services and removes the self-hosted engine configuration file.Note
The host will be visible, but shown as unavailable when runninghosted-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. - Optionally, click Remove to open the Remove Host(s) confirmation window, and click OK.
