HTTP 507 Insufficient Storage — Server Disk Space Exhausted

HTTP 507 Insufficient Storage means the server cannot store the representation needed to complete the request, typically due to exhausted disk space. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Originally from WebDAV (RFC 4918) but applicable to any storage scenario. Server ran out of disk space, quota, or storage allocation. Can affect file uploads, database writes, log files, and temporary files. Different from 413 Payload Too Large — 507 is server storage, 413 is request size. May also indicate database storage quota exceeded. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: Server disk space full from logs, temp files, or uploads. Database storage quota exceeded. Cloud storage bucket hitting its quota limit. Temporary files not being cleaned up properly. Large log files consuming all available disk space. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Check server disk space: df -h on Linux/Mac. Find large files: du -sh /* | sort -rh | head -20. Clean up old logs: find /var/log -name '*.gz' -mtime +30 -delete. Set up log rotation with logrotate to prevent future disk exhaustion. Increase disk allocation or add additional storage if consistently running low. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
