Kubernetes / Storage, Configuration & Data Protection
Find a read-only mount configuration before blaming the application
A write can fail because the workload intentionally mounted data read-only, the backend enforces it or the filesystem entered a protective state.
Environment and inputs: Kubernetes · kubectl with supported client/server versions and delegated RBAC. Examples use namespace app unless noted. Check context, namespace, APIs and provider support first.
Start with this check
Confirm the environment and replace sample objects, namespaces, images, paths and hosts with approved targets. Share only relevant, sanitized output. Follow the workload owner’s process for changes.
kubectl -n app get pod web-0 -o jsonpath='{.spec.containers[*].volumeMounts}{" "}{.spec.volumes}'Read the result
The specification exposes mount intent and volume sources. It does not establish the backend filesystem's current health or effective mount options.
Resolve and verify
Identify the precise failing path and compare declared mode with storage events and application design. Correct the verified layer and test a safe intended write.
Before changing production
Do not switch a protective filesystem read-write over unresolved storage errors or weaken deliberately read-only configuration mounts.
