Symptom & Impact

Services crash or refuse writes because root filesystem reaches 100 percent use.

Environment & Reproduction

Root Cause Analysis

Unbounded file growth or insufficient retention policy consumes disk capacity.

Solution – Primary Fix

Remove safe temporary files, rotate logs, clear caches, and expand volume if required.

Solution – Alternative Approaches

Move high-churn paths to separate partitions or attached storage.

Verification & Acceptance Criteria

Root partition returns below threshold and blocked services recover fully.
