Note
The pipeline used in this section is a wrapper for Ceph - remove node, which simplifies common operations.
This section describes how to remove a Ceph OSD daemon from the cluster without removing the entire Ceph OSD node.
To remove a Ceph OSD daemon:
Log in to the Jenkins web UI.
Open the Ceph - remove osd pipeline.
Specify the following parameters:
| Parameter | Description and values |
|---|---|
| SALT_MASTER_CREDENTIALS | The Salt Master credentials to use for connection, defaults to
salt. |
| SALT_MASTER_URL | The Salt Master node host URL with the salt-api port, defaults to
the jenkins_salt_api_url parameter. For example,
http://172.18.170.27:6969. |
| HOST | The Salt target name of the host from which the Ceph OSD daemons are
going to be removed. For example, osd005*. |
| OSD | A comma-separated list of Ceph OSD daemons to remove while keeping the rest and the entire node as part of the cluster. Do not leave this parameter empty. |
| WAIT_FOR_HEALTHY | Verify that this parameter is selected as it enables the Ceph health check within the pipeline. |
| CLEAN_ORPHANS | Select to clean orphaned disks of Ceph OSDs that are no longer part of the cluster. |
| FAST_WIPE | Deselect if the entire disk needs zero filling. |
Click Deploy.
