0upvotes

Diagnoses GKE persistent-storage failures — volume attach/mount errors (Regional PD on optimized VMs, fsGroup mount timeouts), disk-performance and node storage-pressure issues, slow-disk Pod-creation failures, volume-expansion problems, Local SSD / Hyperdisk Storage Pool creation errors, and Cloud Storage FUSE OOM. Use when Pods are stuck in ContainerCreating, volumes fail to attach or mount, or nodes report storage pressure. Don't use for routine storage provisioning or StorageClass/PVC authoring (see the gke-storage skill).

# GKE Storage Troubleshooting Skill

Use this skill to systematically diagnose and resolve **persistent-storage
failures** for workloads running on GKE — volume attach/mount errors, disk
performance and node storage pressure, volume expansion, storage-related
cluster/node-pool creation errors, and Cloud Storage FUSE memory issues. This
skill operates non-interactively and enforces a read-only diagnostics boundary
before proposing manifest or configuration corrections.

> For routine storage **provisioning** and StorageClass/PVC authoring, use the
> `gke-storage` skill instead. This skill focuses on **failure diagnosis**.
