Symptom & Impact

Build jobs fail with no space left on device in /tmp.

Environment & Reproduction

Large temporary artifacts generated on hosts using default tmpfs sizing.

Root Cause Analysis

/tmp tmpfs allocation is insufficient for workload peak.

Quick Triage

Check df -h /tmp and identify largest temp consumers with du.

Step-by-Step Diagnosis

Review systemd tmp.mount options and concurrent pipeline behavior.

Solution – Primary Fix

Increase tmpfs size or redirect TMPDIR to larger persistent filesystem.

Solution – Alternative Approaches

Implement job-level cleanup and artifact size limits.

Verification & Acceptance Criteria

Pipelines complete without temporary storage exhaustion.

Rollback Plan

Restore previous mount options and restart affected services.

Prevention & Hardening

Capacity-plan temp storage against worst-case concurrent workloads.

Related Errors & Cross-Refs

No space left on device for temporary file creation.
