Source And Intent

infra-run exists to present infrastructure operations work in a form that can be reviewed without exposing employer systems, hostnames, storage identifiers, tickets, or internal procedures.

The project is inspired by professional Linux and infrastructure operations work: prechecks before changes, postchecks after changes, disk-pressure incidents, SSH and sudo hardening, storage expansion planning, cluster awareness, and the need to leave clear notes for other engineers.

What Is Realistic

  • The workflow shape: precheck, dry-run, execute only with explicit approval, postcheck, and report.
  • The operational topics: Linux health checks, disk-full triage, Veritas VxVM/VCS concepts, GPFS / IBM Spectrum Scale concepts, and selected OS hardening controls.
  • The caution around storage, clustering, SSH, sudo, audit, and filesystem changes.

What Is Simplified

  • Commands are written as examples and do not cover every vendor, OS release, package layout, or site standard.
  • The Veritas and GPFS scripts model common workflow steps but cannot validate a real cluster from this repository.
  • The Ansible roles apply selected baseline controls; they are not full compliance implementations.
  • Reporting examples use sanitized sample data.

What Was Sanitized

  • Hostnames, IP addresses, disk names, WWNs, ticket numbers, application names, company names, and environment-specific values.
  • Exact production procedures and internal approval paths.
  • Any data that could identify a real system or organization.

Production Caution

Do not run these scripts blindly on production systems. Review every command, adapt variables and paths, test in a lab, confirm backups and rollback plans, and follow the local change process.

This project does not claim that the exact scripts were used in production.
