Symptom & Impact

Deployments can alter ownership and break service runtime access paths.

Environment & Reproduction

Application cannot read, write, or execute required files.

Root Cause Analysis

Hosts using artifact extraction, rsync, or container to host bind mounts.

Quick Triage

Incorrect uid gid ownership, restrictive mode bits, or missing ACL entries.

Step-by-Step Diagnosis

Capture failing path, process user, and effective permissions.

Solution – Primary Fix

Correct owner and mode on affected paths and restart service.

Solution – Alternative Approaches

Embed permission normalization into deployment pipeline steps.

Verification & Acceptance Criteria

Confirm service can access all required resources without errors.

Rollback Plan

Codify filesystem permissions in infrastructure as code.

Prevention & Hardening

Alert on recurring EACCES and EPERM messages in logs.

Related Errors & Cross-Refs

Re-deploy previous artifact with known permission baseline.
