# 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

## Test Results

```

## Usage

### Start RAID WebDAV Server
```bash
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
