Chapter 2. OpenShift Data Foundation deployed using local storage devices 2.1. Replacing storage nodes on bare metal infrastructure To replace an operational node, see Section 2.1.1, "Replacing an operational node on bare metal user-provisioned infrastructure" To replace a failed node, see Section 2.1.2, "Replacing a failed node on bare metal user-provisioned infrastructure" 2.1.1. Replacing an operational node on bare metal user-provisioned infrastructure Prerequisites Red Hat recommends that replacement nodes are configured with similar infrastructure, resources, and disks to the node being replaced. You must be logged into the OpenShift Container Platform (RHOCP) cluster. If you upgraded to OpenShift Data Foundation version 4.8 from a version, and have not already created the LocalVolumeDiscovery and LocalVolumeSet objects, do so now by following the procedure described in Post-update configuration changes for clusters backed by local storage . Procedure Identify the NODE and get labels on the node to be replaced. Identify the mon (if any) and OSDs that are running in the node to be replaced. Scale down the deployments of the pods identified in the step. For example: Mark the node as unschedulable. Drain the node. Delete the node. Get a new bare metal machine with required infrastructure. See Installing a cluster on bare metal . Important For information about how to replace a master node when you have installed OpenShift Data Foundation on a three-node OpenShift compact bare-metal cluster, see the Backup and Restore guide in the OpenShift Container Platform documentation. Create a new OpenShift Container Platform node using the new bare metal machine. Check for certificate signing requests (CSRs) related to OpenShift Container Platform that are in Pending state: Approve all required OpenShift Container Platform CSRs for the new node: Click Compute Nodes in OpenShift Web Console, confirm if the new node is in Ready state. Apply the OpenShift Data Foundation label to the new node using any one of the following: From User interface For the new node, click Action Menu (...) Edit Labels . Add cluster.ocs.openshift.io/openshift-storage and click Save . From Command line interface Execute the following command to apply the OpenShift Data Foundation label to the new node: Identify the namespace where OpenShift local storage operator is installed and assign it to local_storage_project variable: For example: Add a new worker node to localVolumeDiscovery and localVolumeSet . Update the localVolumeDiscovery definition to include the new node and remove the failed node. Remember to save before exiting the editor. In the above example, server3.example.com was removed and newnode.example.com is the new node. Determine which localVolumeSet to edit. Update the localVolumeSet definition to include the new node and remove the failed node. Remember to save before exiting the editor. In the above example, server3.example.com was removed and newnode.example.com is the new node. Verify that the new localblock PV is available. Change 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: Delete the ocs-osd-removal-job . Example output: Verification steps Execute the following command and 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.

Example output: Verification steps Execute the following command and 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. Ensure that the new incremental mon is created and is in the Running state. Example output: OSD and Mon might take several minutes to get to the Running state. Verify that new OSD pods are running on the replacement node. Optional: If cluster-wide encryption is enabled on the cluster, verify that the new OSD devices are encrypted. For each of the new nodes identified in step, do the following: Create a debug pod and open a chroot environment for the selected host(s). Run "lsblk" and check for the "crypt" keyword beside the ocs-deviceset name(s) If verification steps fail, contact Red Hat Support . 2.5. Replacing storage nodes on Red Hat Virtualization infrastructure To replace an operational node, see Section 2.5.1, "Replacing an operational node on Red Hat Virtualization installer-provisioned infrastructure" To replace a failed node, see Section 2.5.2, "Replacing a failed node on Red Hat Virtualization installer-provisioned infrastructure" 2.5.1. Replacing an operational node on Red Hat Virtualization installer-provisioned infrastructure Use this procedure to replace an operational node on Red Hat Virtualization installer-provisioned infrastructure (IPI). Prerequisites Red Hat recommends that replacement nodes are configured with similar infrastructure, resources and disks to the node being replaced. You must be logged into the OpenShift Container Platform (RHOCP) cluster. If you upgraded to OpenShift Data Foundation version 4.8 from a version, and have not already created the LocalVolumeDiscovery and LocalVolumeSet objects, do so now by following the procedure described in Post-update configuration changes for clusters backed by local storage . Procedure Log in to OpenShift Web Console and click Compute Nodes . Identify the node that needs to be replaced. Take a note of its Machine Name . Get labels on the node to be replaced. Identify the mon (if any) and OSDs that are running in the node to be replaced. Scale down the deployments of the pods identified in the step. For example: Mark the nodes as unschedulable. Drain the node. Click Compute Machines . Search for the required machine. Besides the required machine, click the Action menu (...) Delete Machine . Click Delete to confirm the machine deletion. A new machine is automatically created. Wait for the new machine to start and transition into Running state. Important This activity may take at least 5-10 minutes or more. Click Compute Nodes in the OpenShift web console. Confirm if the new node is in Ready state. Physically add the new device(s) to the node. Apply the OpenShift Data Foundation label to the new node using any one of the following: From User interface For the new node, click Action Menu (...) Edit Labels . Add cluster.ocs.openshift.io/openshift-storage and click Save . From Command line interface Execute the following command to apply the OpenShift Data Foundation label to the new node: Identify the namespace where OpenShift local storage operator is installed and assign it to local_storage_project variable: For example: Add a new worker node to localVolumeDiscovery and localVolumeSet . Update the localVolumeDiscovery definition to include the new node and remove the failed node. Remember to save before exiting the editor. In the above example, server3.example.com was removed and newnode.example.com is the new node. Determine which localVolumeSet to edit. Update the localVolumeSet definition to include the new node and remove the failed node. Remember to save before exiting the editor. In the above example, server3.example.com was removed and newnode.example.com is the new node. Verify that the new localblock PV is available. Change 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 PV associated with the PVC. If there is a PV in Released state, delete it. For example: Identify the crashcollector pod deployment. If there is an existing crashcollector pod, delete it. Delete the ocs-osd-removal job. Example output: Verification steps Execute the following command and 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.
