SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Volume expansion workflows in KubeBlocks can suffer from parity gaps and legacy references. This Skill provides a legacy compatibility shim so cold-start agents can reuse established volume-expansion patterns while guiding them toward the primary kubeblocks-op-volume-expansion path.

Core Features & Use Cases

  • Backward-compatibility shim for volume expansion, keeping legacy references functional while steering to the main entry.
  • Includes safe, templated OpsRequest guidance and pre-checks to verify StorageClass support and cluster health.
  • Use case: migrating from a legacy volume-expansion path to the canonical kubeblocks-op-volume-expansion workflow with minimal disruption.

Quick Start

Follow the primary path kubeblocks-op-volume-expansion for active expansions, using this shim only for legacy references and context.

Frequently Asked Questions about kubeblocks-volume-expansion

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I expand Kubernetes volumes in KubeBlocks safely?▼

Volume expansion in KubeBlocks requires a StorageClass that supports resizing, a healthy cluster state, and no pending OpsRequests. You apply a validated OpsRequest template to resize volumes safely without disrupting online workloads.

What are the prerequisites for Kubernetes volume expansion in KubeBlocks?▼

Volume expansion requires a StorageClass that supports resizing, a healthy cluster state, and no pending OpsRequests. You must validate these conditions before applying an OpsRequest template to perform online resizing.

Can I dry-run a volume expansion OpsRequest in Kubernetes?▼

Yes, KubeBlocks volume expansion guidance provides YAML OpsRequest templates configured for dry-run validation, letting you verify the resize operation safely before applying it to a live cluster.

Why is my KubeBlocks volume expansion not working?▼

Volume expansion fails when the StorageClass lacks resize support, the cluster is unhealthy, or pending OpsRequests block new operations. You must run pre-checks to confirm StorageClass compatibility and cluster health before applying.

How do I migrate from legacy KubeBlocks volume expansion to the canonical path?▼

You use a backward-compatibility shim to keep legacy volume expansion references functional while steering cold-start agents toward the primary kubeblocks-op-volume-expansion workflow, ensuring minimal disruption during migration.
