Symptom & Impact

Disk usage reaches one hundred percent and applications fail to write data.

Environment & Reproduction

Debian 10 servers accumulate logs and snapshots on constrained root volumes.

Root Cause Analysis

Unbounded log growth and retention gaps consume filesystem capacity.

Quick Triage

Find largest paths and check inode consumption before deleting files.

Step-by-Step Diagnosis

Profile disk growth patterns, open deleted files, and journald retention settings.

Solution – Primary Fix

Reclaim space safely, tune log rotation, and enforce retention limits.

Solution – Alternative Approaches

Expand volume capacity or move heavy data paths to dedicated mounts.

Verification & Acceptance Criteria

Free space and inode headroom return above operational safety thresholds.

Rollback Plan

Restore archived log sets and reverted retention policy if required.

Prevention & Hardening

Alert on growth rates and enforce quota or rotation standards.

Related Errors & Cross-Refs

Frequently linked to package install failures and service crash loops.
