Update the localVolumeDiscovery definition to include the new node, and remove the failed node: Example output: Remember to save before exiting the editor. In this example, server3.example.com is removed, and newnode.example.com is the new node. Determine the localVolumeSet to edit: Example output: Update the localVolumeSet definition to include the new node, and remove the failed node: Example output: Remember to save before exiting the editor. In the this example, server3.example.com is removed and newnode.example.com is the new node. Verify that the new localblock Persistent Volume (PV) is available: Example output: Navigate to the openshift-storage project: Remove the failed OSD from the cluster. You can specify multiple failed OSDs if required: <failed_osd_id> Is the integer in the pod name immediately after the rook-ceph-osd prefix. You can add comma separated OSD IDs in the command to remove more than one OSD, for example, FAILED_OSD_IDS=0,1,2 . The FORCE_OSD_REMOVAL value must be changed to true in clusters that only have three OSDs, or clusters with insufficient space to restore all three replicas of the data after the OSD is removed. Verify that the OSD was removed successfully by checking the status of the ocs-osd-removal-job pod. A status of Completed confirms that the OSD removal job succeeded. Ensure that the OSD removal is completed. Example output: Important If the ocs-osd-removal-job fails, and the pod is not in the expected Completed state, check the pod logs for further debugging: For example: Identify the Persistent Volume (PV) associated with the Persistent Volume Claim (PVC): Example output: If there is a PV in Released state, delete it: For example: Example output: Identify the crashcollector pod deployment: If there is an existing crashcollector pod deployment, delete it: Delete the ocs-osd-removal-job : Example output: Verification steps Verify that the new node is present in the output: Click Workloads -> Pods . Confirm that at least the following pods on the new node are in Running state: csi-cephfsplugin-* csi-rbdplugin-* Verify that all other required OpenShift Data Foundation pods are in Running state.
