January 27, 2026 - PVC namespace rebinding with rebind-pvc.sh utility

Automate binding persistent volumes to new namespaces with the rebind-pvc.sh script

Update Storage Distributed File Storage documentation now includes instructions for rebinding PVCs to new namespaces using the rebind-pvc.sh utility script.

Overview​

Rebinding a Persistent Volume Claim (PVC) makes an existing persistent volume's storage available in a different namespace. This is useful when you need to migrate workloads or share storage across namespaces while preserving your data.

The CoreWeave documentation now includes guidance on using the rebind-pvc.sh utility script.

What's new​

Automated PVC rebinding​

The documentation now references the rebind-pvc.sh utility script, which automates the process of binding an existing PVC's underlying storage volume to a new namespace. The script generates the necessary Kubernetes manifests, eliminating the need to manually create PersistentVolume and PersistentVolumeClaim resources.

Key benefits​

  • Simplified workflow: The script automates manifest generation, reducing manual configuration errors.
  • Namespace migration: Move workloads between namespaces while preserving data.
  • Storage sharing: Make the same persistent volume accessible in multiple namespaces.
  • Complete documentation: Includes installation instructions, usage examples, and teardown procedures.
