5.5. Recovering from failure when expanding volumes

Procedure

1. Mark the persistent volume (PV) that is bound to the PVC with the Retain reclaim policy. This can be done by editing the PV and changing persistentVolumeReclaimPolicy to Retain.
2. Delete the PVC. This will be recreated later.
3. To ensure that the newly created PVC can bind to the PV marked Retain, manually edit the PV and delete the claimRef entry from the PV specs. This marks the PV as Available.
4. Re-create the PVC in a smaller size, or a size that can be allocated by the underlying storage provider.
5. Set the volumeName field of the PVC to the name of the PV. This binds the PVC to the provisioned PV only.
6. Restore the reclaim policy on the PV.
