Rescue disk pressure hunt
Extreme Linux arena: du, df, sort, and safe cleanup planning
Log in and clear the lower tiers to unlock this mission.
Missing prerequisites: linux-easy-disk-pressure
A node is minutes from filling its root volume, but deleting the wrong cache can break deploys. You are working inside a Linux production host, and the arena only clears when the result is safe, deterministic, and explainable.
Learn to apply du, df, sort, and safe cleanup planning in a Linux production host while explaining the invariant, safety constraints, and hidden edge cases.
- Demonstrates du, df, sort, and safe cleanup planning
- Handles the visible sample and hidden edge cases
- Keeps output deterministic and explainable
- Avoids destructive host commands
