RAID WebDAV Integration - Complete

Date: 2026-05-17

Status: Phase 1 Complete (100%)

Implemented Features

Core RAID Module

• ✅ parity.rs (105 lines) - XOR Parity calculation
• ✅ level_5.rs (197 lines) - RAID 5 read/write logic
• ✅ controller.rs (134 lines) - RAID controller (RAID 0/1/5)
• ✅ exporter.rs (95 lines) - RAID to virtual disk export

WebDAV Integration

• ✅ raid_webdav_auto.rs (135 lines) - Auto-mount WebDAV server
• ✅ Auto-mount sparseimage on startup
• ✅ Mount point verification
• ✅ WebDAV handler configuration

Usage

Start RAID WebDAV Server

cargo run --bin raid_webdav_auto \
  --vdisk-path data/raid_simple.sparseimage \
  --mount-name RAID_AUTO \
  --port 4933

macOS Finder Mount

1. Finder → Cmd+K
2. http://localhost:4933/webdav
3. Connect (Guest/Guest)
4. Access test_video.mp4 (258MB)

Performance

• Virtual disk: 258MB test file
• Mount time: <3 seconds
• WebDAV overhead: minimal (local filesystem)

Next Steps

1. Performance testing (throughput measurement)
2. RAID 6 implementation (Reed-Solomon)
3. RAID 10/50/60 (nested RAID)
4. Multi-user WebDAV support

Code Quality

• Total lines: 666 (RAID + WebDAV)
• Tests: 5 passed
• Coverage: parity, level_5, exporter
• Documentation: docs/RAID_MODULE_PROGRESS.md
