Linux No Space Left on Device

Overview

Linux "No space left on device" means the filesystem is completely full and cannot accept any new data.

Key Details

• errno 28 (ENOSPC) — filesystem full
• Can also mean inode exhaustion (small files fill inodes)
• Services may crash when they cannot write logs
• Database operations will fail on a full filesystem

Common Causes

• Log files consuming all available space
• Large temporary files or downloads
• Docker images/containers using disk space
• Inode limit reached with millions of small files

Steps

1. 1Check space: df -h and inodes: df -i
2. 2Find large files: find / -type f -size +100M
3. 3Clean logs: sudo journalctl --vacuum-size=500M
4. 4Clean Docker: docker system prune -a
