PV rebuild

Overview

The PV Rebuild feature enables users to restore Persistent Volumes (PVs) and Volume Snapshot Contents (VSCs) when reinstalling Kubernetes (K8s) or OpenShift (OCP) instead of performing an upgrade. This feature ensures data retention during an InfoScale cluster rebuild and is also useful in cases where the K8s/OCP setup is accidentally destroyed.

Enabling and disabling PV rebuild

By default, the pv-rebuild feature is enabled.

Check the PV rebuild status

To verify whether PV rebuild is enabled, run the following command:

# oc describe infoscalecluster -n infoscale-vtas <infoscale_cluster_name> "infoscale.veritas.com/pv-rebuild"

Disable the PV rebuild feature

To disable the PV rebuild feature, use the following command:

# oc annotate infoscalecluster -n infoscale-vtas <infoscale_cluster_name> "infoscale.veritas.com/pv-rebuild"="disabled" - overwrite

Note:

Ensure that the cluster ID and cluster name remain the same during the InfoScale cluster rebuild.

Restoring PVs and VSCs after cluster rebuild
  1. Restore PVs and PVCs

    • After the InfoScale cluster rebuild, PVs will be in an available state.

    • To bind PVs to Persistent Volume Claims (PVCs), reapply the same YAML files used for PVC creation.

    • Once applied, the PVCs and PVs will transition to the Bound state.

  2. Restore VSCs to Volume Snapshots (VS)

    • Modify the existing Volume Snapshot (VS) YAML file with the following change:

      volumeSnapshotContentName: <vsc_name>

    • Ensure that the VS and VSC names match correctly.

    • Retrieve the names of all Volume Snapshot (VS) and Volume Snapshot Contents (VSCs) using the following command:

      # oc get vsc -A
