SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

EFS troubleshooting helps diagnose and resolve mount failures, NFS timeouts, permission errors, throughput problems, and burst credit exhaustion. Use when an EFS file system is not mounting, returning errors, performing slowly, or showing access denied.

Core Features & Use Cases

  • Verify dependencies and readiness before troubleshooting EFS
  • Classify common issues (mount, network, IAM, performance) and apply fixes
  • Use case: when an EC2 instance cannot mount an EFS file system, apply these steps to identify the root cause and implement recommended remediation
  • Collect logs and diagnostics for AWS Support

Quick Start

Describe the symptoms of the EFS issue and follow the guided steps to diagnose and resolve mounting or permission problems.

FAQPage Schema
Why does my Amazon EFS mount fail on my EC2 instance?▼

Amazon EFS mount failures on EC2 instances are typically caused by network connectivity issues, incorrect DNS resolution, or missing NFS utilities. This Skill classifies the specific failure type and provides targeted remediation commands to resolve the mount error.

How do I fix EFS permission errors and access denied issues?▼

To fix EFS permission errors and access denied issues, you must verify IAM roles, security group rules, and NFS export policies. This Skill guides you through checking network access and IAM configurations to restore proper file system permissions.

What should I do when experiencing NFS timeouts with Amazon EFS?▼

When experiencing NFS timeouts with Amazon EFS, check VPC network configurations, security group ingress rules, and route table settings. This Skill helps classify whether the timeout stems from network restrictions or performance bottlenecks.

How can I resolve EFS throughput problems and burst credit exhaustion?▼

Resolving EFS throughput problems and burst credit exhaustion requires analyzing file system performance metrics and access patterns. This Skill helps identify performance limits and recommends adjustments to throughput mode or capacity provisioning.

Does this Skill support troubleshooting EFS across different VPCs?▼

Yes, this Skill supports troubleshooting Amazon EFS across VPCs, including scenarios involving network routing, peering connections, and cross-account access. It verifies dependencies and classifies issues specific to complex networking architectures.
