Node Storage Usage Exceeds Threshold

Kubernetes nodes require sufficient storage availability to ensure smooth operation of system processes and workloads. When storage availability on a node falls below a defined percentage (default: 20%) of its total capacity, it can lead to degraded performance or system failures.

Common Causes​

  • Rapid growth in temporary files and/or logs.
  • Inefficient storage allocation strategies.
  • Unmonitored disk usage over time.
