Symptom & Impact

Backup workflows can fail on RHEL 7 when scripts execute binaries from a filesystem mounted with noexec.

Environment & Reproduction

Jobs trigger but terminate early with permission denied or cannot execute errors in scheduled logs.

Root Cause Analysis

Temporary work directory on noexec mount, hardcoded script path assumptions, or service user environment differences.

Quick Triage

Inspect mount options, crond execution context, and service account permissions for backup runtime directories.

Step-by-Step Diagnosis

Use journalctl and job logs to trace the failing command and confirm execution restriction at filesystem level.

Solution – Primary Fix

Review backup script temp path variables and mount configuration to select an executable secure location.

Solution – Alternative Approaches

Move temp execution path, update script variables, restart scheduling service if needed, and rerun backup validation.

Verification & Acceptance Criteria

SELinux labels on new temp paths must allow script operation; firewalld applies only for remote backup targets.

Rollback Plan

Confirm full backup completion and verify restore test while monitoring journalctl for repeated execution denials.

Prevention & Hardening

Revert script changes if new path introduces other failures and use a tested alternate workspace.

Document mount policy assumptions and include preflight checks in backup automation.
