Use when Kubernetes storage blocks a workload: a PersistentVolumeClaim stuck in Pending, ProvisioningFailed events, a StorageClass that does not exist or a provisioner that cannot provide the access mode, pods Pending with "unbound immediate PersistentVolumeClaims", FailedAttachVolume, FailedMount or Multi-Attach errors, a PVC or PV stuck Terminating or Released, or a volume that is full or will not expand. Investigates with kubectl get, describe and events, and proposes fixes. Reads first and…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Kubernetes storage troubleshooting Find out why a volume does not get to a pod, or why it does not work once it is there, and propose a fix. **Read first, ask before changing.** Run the investigation commands freely. Run a command under an "Ask first" line only after the user approves that exact command; if your credentials do not allow it, give it to the user to run. Never run a "Proposed fix"; hand it to the user. Volumes hold data, and many storage changes cannot be undone: a volume cannot shrink, a deleted claim can take its data with it, and most of a claim's spec cannot change after it is created. So most fixes here are proposed fixes, with the reason said. The commands use placeholders: `my-namespace`, `my-app`, `my-pod`, `my-data` (the PVC), `my-pv`, `my-class` and `my-node`. Replace them with the real names. Never read Secrets (a StorageClass or CSI driver may reference some; read their names only). If output contains passwords, tokens or keys, do not repeat them. ## When to use - A PVC is `Pending`, or a pod is `Pending` because of its PVC. - `ProvisioningFailed`, `FailedAttachVolume`, `FailedMount` or `Multi-Attach error` events. …

How to install
mdr add k8s-servant/k8s-skills/k8s-storage-troubleshooting@sha256:939cea6bc47b7aeaThe line at the top of this page pins the label git:20261031.a5d0ab1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
