Symptom & Impact

File operations fail on NFS paths with stale handle errors.

Environment & Reproduction

Common after server-side export changes or inode replacement.

Root Cause Analysis

Client handle points to file object no longer valid on server.

Quick Triage

Confirm server export health and client mount state immediately.

Step-by-Step Diagnosis

Compare export IDs, mount options, and recent storage events.

Solution – Primary Fix

Clear stale mount, remount cleanly, and refresh export definitions.

Solution – Alternative Approaches

Use automount with timeout policies to reduce stale sessions.

Verification & Acceptance Criteria

Read/write operations succeed and no stale errors recur.

Rollback Plan

Revert export changes and restore previous mount options.

Prevention & Hardening

Coordinate NFS export changes with controlled client remount windows.
