Symptom & Impact

Applications fail with `ESTALE` on NFS-mounted volumes, breaking shared web roots and home dirs.

Environment & Reproduction

Triggered after server-side directory removal or export resync without client remount.

Root Cause Analysis

File handles on the client reference inodes that no longer exist on the server.

Quick Triage

Run `ls` in the mount and capture exact error messages.

Step-by-Step Diagnosis

Check exports with `exportfs -v` on the server and `mount | grep nfs` on the client.

Solution – Primary Fix

Solution – Alternative Approaches

Reboot the client if hard mounts hold processes in uninterruptible sleep.

Verification & Acceptance Criteria

Mount succeeds and applications enumerate files without ESTALE.

Rollback Plan

Roll back to the previous export configuration via configuration management.

Prevention & Hardening

Use stable export IDs and coordinate directory changes with client teams.

Pairs with `nfs: server not responding` warnings in dmesg.
