Verify Dependencies\n\n- You MUST verify `aws` CLI is available with `s3files` subcommand support\n- You MUST confirm valid AWS credentials\n- You MUST ONLY check for tool existence and version — MUST NOT execute destructive or mutating commands during verification\n- You MUST inform the user if any required tools are missing\n- You MUST respect the user's decision to abort if tools are unavailable\n- You SHOULD explain steps before executing and wait for user confirmation on write commands\n\n### 1. Classify the Issue\n\n| Symptom | Category |\n|---|---|\n| mount.s3files: command not found | A: Client Installation |\n| Connection timed out during mount | B: Network\u002FSecurity Group |\n| Mount hangs indefinitely (no timeout) | B: Network\u002FSecurity Group |\n| Access denied during mount | C: IAM Permissions |\n| File system stuck in \"creating\" | C: IAM Permissions |\n| Permission denied on file operations | C: IAM Permissions |\n| Files not appearing in S3 after write | D: Synchronization |\n| Files in .s3files-lost+found directory | E: Conflict Resolution |\n| Slow reads or high latency | F: Performance |\n| NFS server error | G: Encryption\u002FKMS |\n| DNS name resolution fails | H: VPC DNS |\n\n### 2. Category A — Client Installation\n\n`mount.s3files: command not found` means `amazon-efs-utils` is missing or \u003C v3.0.0.\n\n```bash\nsudo yum -y install amazon-efs-utils  # Amazon Linux\n```\n\n### 3. Category B — Network\u002FSecurity Group\n\nConnection timeout is the #1 mount failure — almost always security groups.\n\nVerify mount target exists in the instance's AZ:\n\n```bash\naws s3files list-mount-targets --file-system-id fs-ID --region REGION\n```\n\nCross-AZ mounting works but adds latency.\n\nVerify security groups — most common fix:\n\n- Mount target SG MUST have inbound TCP 2049 from compute SG\n- Compute SG MUST have outbound TCP 2049 to mount target SG\n- Fix: `aws ec2 authorize-security-group-ingress --group-id sg-MT --protocol tcp --port 2049 --source-group sg-COMPUTE`\n\nTest connectivity:\n\n```bash\nnc -zv az-ID.fs-ID.s3files.REGION.on.aws 2049\n```\n\n> **Note:** These SG troubleshooting steps also apply to EFS — use `aws efs describe-mount-targets` instead.\n\n**Mount hangs in isolated VPC**: If the VPC has no internet access, S3 Files requires a CloudWatch Logs VPC endpoint (`com.amazonaws.REGION.logs`) for mount to complete.\n\n### 4. Category C — IAM Permissions\n\n**File system stuck in \"creating\" status:**\nS3 Files does NOT validate IAM role permissions at creation time. Wrong trust policy or missing permissions → stuck in `creating` with access denied in `statusMessage`.\n\nCheck status:\n\n```bash\naws s3files get-file-system --file-system-id fs-ID --region REGION\n```\n\nCheck `statusMessage`. If access denied, fix the IAM role and delete\u002Frecreate.\n\n**Mount access denied:** Compute role needs `s3files:ClientMount`. For dev\u002Ftest only, `AmazonS3FilesClientFullAccess` is acceptable — avoid in production.\n\n**Write permission denied:** Compute role needs `s3files:ClientWrite`\n\n**Root access denied:** Compute role needs `s3files:ClientRootAccess`. ⚠️ Bypasses POSIX permissions — prefer access points with scoped POSIX users.\n\n**Check file system policy:**\n\n```bash\naws s3files get-file-system-policy --file-system-id fs-ID --region REGION\n```\n\n### 5. Category D — Synchronization\n\n**Files not appearing in S3:** Writes sync within ~60 seconds. Check status:\n\n```bash\ngetfattr -n \"user.s3files.status;$(date -u +%s)\" filename --only-values\n```\n\nCommon ExportError values:\n\n| Error | Fix |\n|---|---|\n| S3AccessDenied | File system IAM role lacks S3 write permissions |\n| S3BucketNotFound | Bucket deleted or renamed |\n| RoleAssumptionFailed | Trust policy misconfigured |\n| EncryptionKeyInaccessible | KMS key disabled or permissions revoked |\n| PathTooLong | File path exceeds 1,024 byte S3 key limit |\n\nMonitor: `PendingExports` CloudWatch metric. Growing = exceeds 800 files\u002Fsec rate.\n\n### 6. Category E — Conflict Resolution\n\nFiles in `.s3files-lost+found-{fs-id}` = sync conflict (modified via FS and S3 simultaneously). S3 wins; FS version moved to lost+found.\n\n### 7. Category F — Performance\n\n**First access latency:** Normal — first directory access imports metadata.\n\n**Intelligent read routing not working:** Compute role needs `s3:GetObject` on the bucket.\n\n**Slow writes:** If `PendingExports` growing, distribute across multiple file systems.\n\n### 8. Category G — Encryption\u002FKMS\n\nNFS server error with encrypted FS = KMS issue. Verify key is enabled and role has KMS permissions.\n\n### 9. Category H — VPC DNS\n\nDNS resolution failure = VPC DNS settings disabled.\n\n```bash\naws ec2 describe-vpc-attribute --vpc-id vpc-ID --attribute enableDnsHostnames\naws ec2 describe-vpc-attribute --vpc-id vpc-ID --attribute enableDnsSupport\n```\n\nBoth MUST be `true`. If not:\n\n```bash\naws ec2 modify-vpc-attribute --vpc-id vpc-ID --enable-dns-hostnames Value=true\naws ec2 modify-vpc-attribute --vpc-id vpc-ID --enable-dns-support Value=true\n```\n\n## Troubleshooting\n\n### AWS CLI endpoint URL cannot be resolved\nCLI is too old for S3 Files. Run `aws --version` — if v1.x, upgrade to AWS CLI v2: [Installing the AWS CLI](https:\u002F\u002Fdocs.aws.amazon.com\u002Fcli\u002Flatest\u002Fuserguide\u002Fgetting-started-install.html).\n\n### ECS task fails with DNS resolution error\nUsed `efsVolumeConfiguration` instead of `s3filesVolumeConfiguration`. Fix: use `fileSystemArn` in S3 Files-specific volume config.\n\n### S3 Files vs other products confusion\nS3 Files is NOT Mountpoint for S3, S3 File Gateway, or File Cache. Uses `aws s3files` CLI, `s3files:` IAM actions, `mount -t s3files`.\n\n### Enable Debug Logs\n\nSet `logging_level = DEBUG` in `\u002Fetc\u002Famazon\u002Fefs\u002Fs3files-utils.conf`. Logs at `\u002Fvar\u002Flog\u002Famazon\u002Fefs\u002Fmount.log`.\n\n### Collect Logs for AWS Support\n\n```bash\nsudo tar -czf \u002Ftmp\u002Fs3files-logs.tar.gz \u002Fvar\u002Flog\u002Famazon\u002Fefs\u002F \u002Fetc\u002Famazon\u002Fefs\u002Fs3files-utils.conf\n```\n\n## Security Considerations\n\n- When diagnosing IAM issues, verify least-privilege — avoid FullAccess as a shortcut\n- Without a file system policy, any VPC client can mount\n- Restrict `\u002Fvar\u002Flog\u002Famazon\u002Fefs\u002F` access — logs contain S3 key names\n\n## Additional Resources\n\n- [S3 Files Troubleshooting](https:\u002F\u002Fdocs.aws.amazon.com\u002FAmazonS3\u002Flatest\u002Fuserguide\u002Fs3-files-troubleshooting.html)\n- [S3 Files Best Practices](https:\u002F\u002Fdocs.aws.amazon.com\u002FAmazonS3\u002Flatest\u002Fuserguide\u002Fs3-files-best-practices.html)\n- [S3 Files Quotas](https:\u002F\u002Fdocs.aws.amazon.com\u002FAmazonS3\u002Flatest\u002Fuserguide\u002Fs3-files-quotas.html)\n",{"data":36,"body":38},{"name":4,"description":6,"version":37},1,{"type":39,"children":40},"root",[41,49,56,62,78,84,91,142,148,316,322,340,389,395,400,405,449,454,459,483,488,519,542,560,566,591,596,635,647,673,688,705,713,752,758,768,829,834,921,934,940,953,959,969,986,1003,1009,1014,1020,1025,1102,1115,1197,1203,1209,1230,1236,1265,1271,1299,1305,1333,1339,1378,1384,1410,1416,1447],{"type":42,"tag":43,"props":44,"children":45},"element","h1",{"id":4},[46],{"type":47,"value":48},"text","Troubleshooting S3 Files",{"type":42,"tag":50,"props":51,"children":53},"h2",{"id":52},"overview",[54],{"type":47,"value":55},"Overview",{"type":42,"tag":57,"props":58,"children":59},"p",{},[60],{"type":47,"value":61},"Diagnoses and resolves Amazon S3 Files issues: mount failures, IAM\npermissions, synchronization, conflict resolution, and performance.",{"type":42,"tag":57,"props":63,"children":64},{},[65,67,76],{"type":47,"value":66},"For authoritative guidance, see ",{"type":42,"tag":68,"props":69,"children":73},"a",{"href":70,"rel":71},"https:\u002F\u002Fdocs.aws.amazon.com\u002FAmazonS3\u002Flatest\u002Fuserguide\u002Fs3-files-troubleshooting.html",[72],"nofollow",[74],{"type":47,"value":75},"S3 Files Troubleshooting",{"type":47,"value":77},".",{"type":42,"tag":50,"props":79,"children":81},{"id":80},"common-tasks",[82],{"type":47,"value":83},"Common Tasks",{"type":42,"tag":85,"props":86,"children":88},"h3",{"id":87},"_0-verify-dependencies",[89],{"type":47,"value":90},"0.
