# MeshXFS: AI-generated clustered file-system based on XFS

> **Key takeaway:** MeshXFS is an open-source clustered file-system where all code modifying the original XFS driver was written by AI.

## Summary
The MeshXFS project has released a POSIX clustered file-system created by using Claude Opus as an autonomous coding agent. The project adapted the existing XFS driver to support distributed locking, multi-node concurrent access, fencing, and crash recovery. While the project uses upstream XFS code, all additions and modifications were generated by AI models.

## Technical implementation of MeshXFS
- Uses **Claude Opus** as the primary agent, consulting other models like **GPT**, **Gemini**, and **Astra** for complex logic.
- Implements two distributed lock managers: one network-based and one using **SCSI COMPARE AND WRITE** on shared disks.
- Features cache coherency, fencing via **SCSI persistent reservations**, and survivor-led journal recovery.
- Includes an on-disk envelope and userspace tools such as **mkfs**, **fsck**, and **resize**.
- The modified XFS code grew from approximately 226k to 314k lines.

## Why it matters
This project serves as an experiment in using autonomous AI agents to develop complex kernel-level software, though it raises questions regarding data integrity in AI-generated storage solutions.
