SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps users understand and manage disk space on their systems, preventing issues like "disk full" errors and optimizing storage.

Core Features & Use Cases

  • Filesystem Usage: Reports disk space usage at the filesystem level, showing total size, used space, available space, and percentage used.
  • Inode Monitoring: Checks inode usage, crucial for diagnosing "no space left on device" errors when disk blocks aren't actually full.
  • Use Case: When a server alerts "disk full," this Skill can quickly identify which filesystem is at capacity and whether the issue is due to file size or inode exhaustion.

Quick Start

Use the df skill to show human-readable disk space usage for all filesystems, excluding temporary ones.

FAQPage Schema
How do I check disk space usage across Linux filesystems?▼

To check disk space usage, the Skill reports total size, used space, available space, and percentage used at the filesystem level. It parses filesystem block allocation data to provide human-readable output for all mounted Linux partitions.

Why does Linux report no space left on device when disk blocks are not full?▼

The no space left on device error often indicates inode exhaustion rather than full disk blocks. The Skill monitors inode usage by parsing allocation data, helping you diagnose when a filesystem runs out of available inodes for new files.

How do I identify which filesystem is full during a server disk capacity alert?▼

To identify which filesystem is full during a disk capacity alert, the Skill reports usage percentages for all partitions. It excludes temporary filesystems to isolate persistent storage issues affecting your system.

Does monitoring inode usage require coreutils for Linux system administration?▼

Yes, monitoring inode usage requires coreutils to parse filesystem block and inode allocation data. The Skill operates within Linux system administration and DevOps workflows, relying on core utilities to extract capacity metrics.

Can I use this for capacity planning and troubleshooting storage issues in DevOps?▼

Yes, you can use this for capacity planning and troubleshooting storage issues in DevOps workflows. The Skill reports disk space and inode exhaustion metrics, helping administrators anticipate full partitions and prevent disk full errors.
