+## WebDAV 404 Fix + `MB_WEBDAV_USE_S3`（2026-06-24）⭐⭐⭐⭐⭐
+
+**Root cause**: User WebDAV (`/webdav/`) returned 404 because `handle_webdav_multi` used S3Vfs when `s3.enabled=true` in `config/s3.toml`. S3Vfs tried to HEAD local files via `http://localhost:11438/webdav-demo/{path}` which returned 404 → `FsError::NotFound`.
+
+**Fix**: Added `MB_WEBDAV_USE_S3` env var (default `false`), decoupling user WebDAV backend from global S3 config. Admin WebDAV already used `LocalFs` directly.
+
+**Files modified**: `markbase-core/src/server.rs` — line 159-161: `use_s3` now reads from `MB_WEBDAV_USE_S3` env var instead of `s3_cfg.s3.enabled`.
+
+**Verified**: `PROPFIND /webdav/` returns HTTP 207 with full file listing (48 files, 596MB video).

+
+## SMB Samba smbclient Compatibility Fixes（2026-06-24）⭐⭐⭐⭐⭐
+
+**Root causes**: Three bugs preventing Samba smbclient from connecting to MarkBase SMB server.
+
+### Bug #1: cipher_count = 2 (SMB 3.x Negotiate) ✅
+
+**Problem**: Samba smbclient validation check at `smbXcli_negprot_smb2_done()` (line 5931):
+```c
+cipher_count = SVAL(cipher->data.data, 0);
+if (cipher_count != 1) {
+    tevent_req_nterror(req, NT_STATUS_INVALID_NETWORK_RESPONSE);  // ← This was failing!
+}
+```
+
+**Fix**: Changed negotiate.rs to advertise single cipher (AES-128-GCM):
+```rust
+cipher_count: 1,  // Was 2
+ciphers: vec![EncryptionCapabilities::CIPHER_AES_128_GCM],  // Was [AES-GCM, AES-CCM]
+```
+
+### Bug #2: Username Case Sensitivity ✅
+
+**Problem**: ACL lookup was case-sensitive, but SMB usernames should be case-insensitive.
+
+**Fix**: Normalized usernames to lowercase at all points:
+- `ntlm.rs`: `Identity::User { user: auth.user.to_lowercase(), ... }`
+- `builder.rs`: Share.user() + SmbServerBuilder.user() normalize to lowercase
+- `session_setup.rs`: `users.get(&u.to_lowercase())`
+
+### Bug #3: SMB 2.x Signing Key Derivation ✅
+
+**Problem**: SMB 2.x was using SMB 3.0 KDF derivation, but should use session_base_key directly.
+
+**Fix**: Per MS-SMB2 §3.1.4.1:
+```rust
+let signing_key = match dialect {
+    Some(Dialect::Smb311) => [0u8; 16],  // Derived later
+    Some(Dialect::Smb300) | Some(Dialect::Smb302) => signing_key_30(&session_base_key),
+    Some(Dialect::Smb202) | Some(Dialect::Smb210) => session_base_key,  // Direct for SMB 2.x
+    ...
+};
+```
+
+### Verification
+
+| SMB Dialect | smbclient Test | Status |
+|-------------|----------------|--------|
+| SMB 2.02 | `smbclient -m SMB2_02` | ✅ PASS |
+| SMB 2.10 | `smbclient -m SMB2_10` | ✅ PASS |
+| SMB 3.0 | `smbclient -m SMB3` | ✅ PASS |
+| SMB 3.11 | `smbclient -m SMB3_11` | ✅ PASS |
+
+### Commits
+
+| Fix | Commit | Files Changed |
+|-----|--------|---------------|
+| **#1 + #2** | `6f223c9` | negotiate.rs, ntlm.rs, builder.rs |

+
+### Ceph RADOS Integration（搁置）
+
+**文档**: `docs/CEPH_INTEGRATION_ANALYSIS.md`（340 行）
+
+**结论**: 不符合 MarkBase macOS 跨平台定位
+- ❌ Linux-only（librados.so FFI）
+- ⚠️ 需完整 Ceph 集群（Monitor + OSD + MGR）
+- ⚠️ 部署复杂度超出 Lightweight 定位
+
+**推荐替代方案**:
+1. MinIO — S3-compatible，已有 S3Vfs 支持
+2. 内置分布式 — DedupFs + S3Vfs 组合
+
+---
+
+### MinIO Integration（推荐 ⭐⭐⭐⭐⭐）
+
+**文档**: `docs/MINIO_INTEGRATION.md`（200 行）
+
+**优势**:
+- ✅ S3-compatible API（已有 S3Vfs，无需修改代码）
+- ✅ 跨平台（macOS/Linux/Windows）
+- ✅ 轻量级部署（单节点即可）
+- ✅ 高性能（纠删码 + 分布式扩展）
+
+**部署方式**:
+```bash
+# macOS 单节点
+brew install minio/stable/minio
+minio server /data --console-address ":9001"
+
+# Docker
+docker run minio/minio server /data --console-address ":9001"
+```
+
+**集成方式**: 环境变量 + CLI 参数
+```bash
+export MB_S3_ENDPOINT=http://localhost:9000
+export MB_S3_BUCKET=markbase
+export MB_S3_ACCESS_KEY=minioadmin
+export MB_S3_SECRET_KEY=minioadmin
+```
+
+**支持功能**:
+- Versioning（替代 Snapshot）
+- Bucket Policy（ACL 管理）
+- Lifecycle Rules（Backup 清理）
+- Erasure Coding（自动容错）
+
+---
+
+### DedupFs + S3Vfs Combination（设计 ⭐⭐⭐⭐）
+
+**文档**: `docs/DEDUP_S3_COMBINATION.md`（320 行）
+
+**目标**: 分布式 dedup 存储（跨节点共享 dedup 块）
+
+**架构**:
+```
+MarkBase Node A → DedupS3Store → MinIO Cluster
+                     ↓
+MarkBase Node B → DedupS3Store → 共享 Node A 的块
+```
+
+**核心设计**:
+- 块存储到 S3 对象（SHA-256 hash 作为 key）
+- 引用计数存储到 S3 object metadata
+- Manifest 存储到 S3 对象（JSON 格式）
+
+**实现工作量**: ~1000 行（7 phases）
+
+**关键技术挑战**:
+- 引用计数非原子操作（需 versioning 或分布式锁）
+- 网络延迟 overhead（~5-10ms per block vs ~0.1ms local）
+- Dedup ratio 因文件类型差异（VM images ~80%, photos ~5%）
+
+**下一步**:
+1. Phase 1: DedupS3Store struct + basic I/O（~300 行）
+2. Phase 2: CLI integration（~100 行）
+3. Phase 3: Performance benchmark

+# Ceph RADOS Integration Analysis for MarkBase
+
+**Date**: 2026-06-25
+**Status**: Shelved (不符合 macOS 跨平台定位)
+**Library**: ceph-async (4.0.5)
+**Constraint**: Linux-only (requires librados.so symlink)
+
+---
+
+## Executive Summary
+
+### Goal
+Add Ceph RADOS as a VfsBackend option for distributed, highly scalable storage.
+
+### Key Findings
+| Aspect | Finding |
+|--------|---------|
+| **Platform** | ❌ Linux-only (librados.so FFI, macOS needs Docker/VM) |
+| **Deployment** | ⚠️ Requires full cluster (Monitor + OSD + MGR) |
+| **Complexity** | ⚠️⚠️⚠️⚠️⚠️ High (超出 Lightweight 定位) |
+| **Positioning** | ❌ 不符合 MarkBase macOS 跨平台定位 |
+
+### Recommendation
+**当前搁置**。优先考虑：
+1. **MinIO** — S3-compatible，已有 S3Vfs 支持，跨平台
+2. **内置分布式** — DedupFs + S3Vfs 组合，轻量级
+

+
+## Phase 1: CephVfs Core Implementation
+
+### Key Design Decisions
+
+**1. Object vs File mapping**:
+- RADOS is object storage (no directories)
+- Path `/foo/bar.txt` → Object `foo/bar.txt` in pool
+- Directories simulated via zero-byte objects with `/` suffix (like S3)
+
+**2. Pool-per-share vs single pool**:
+- Option A: Single pool + path prefix (simpler, less isolation)
+- Option B: Pool-per-share (better isolation, quota per pool)
+- **Recommend**: Option B (pool-per-share) for enterprise use
+
+**3. I/O context caching**:
+- Each pool requires separate `rados_ioctx_t`
+- Cache ioctx per share to avoid recreation overhead
+
+### CephVfs Struct (Draft)
+
+```rust
+pub struct CephVfs {
+    cluster: rados_t,            // RADOS cluster handle
+    pool_name: String,           // Pool name for this share
+    ioctx: rados_ioctx_t,        // I/O context (cached)
+    root_prefix: String,         // Path prefix within pool
+}
+
+pub struct CephVfsFile {
+    ioctx: rados_ioctx_t,
+    object_id: String,           // Object name in pool
+    position: u64,
+    write_buffer: Vec<u8>,       // Buffer for writes (flush on close)
+    size: u64,
+}
+```
+
+### VfsBackend Method Mapping
+
+| Method | RADOS equivalent | Complexity |
+|--------|-----------------|------------|
+| `read_dir()` | `rados_nobjects_list_*` | High (pagination) |
+| `open_file()` | Custom (object ops) | Medium |
+| `stat()` | `rados_stat()` | Low |
+| `create_dir()` | `rados_write_full(0-byte)` | Low |
+| `remove_dir()` | `rados_remove()` | Low |
+| `remove_file()` | `rados_remove()` | Low |
+| `rename()` | Custom (copy + delete) | Medium |
+| `exists()` | `rados_stat()` | Low |
+| `copy()` | `rados_clone_range()` | Low |
+| `hard_link()` | `rados_clone_range()` | Low |
+| `read_link()` | Unsupported | N/A |
+| `create_symlink()` | Unsupported | N/A |
+
+---
+
+## Risk Assessment
+
+| Risk | Level | Mitigation |
+|------|-------|------------|
+| **Linux-only** | ⚠️⚠️⚠️⚠️⚠️ Critical | Docker/VM for macOS; 不符合跨平台定位 |
+| **librados.so symlink** | ⚠️⚠️⚠️ Medium | Document setup; CI check |
+| **Pool-level snapshots** | ⚠️⚠️ Low | Document limitation; consider RGW |
+| **Async overhead** | ⚠️⚠️⚠️ Medium | Benchmark; spawn_blocking wrapper |
+| **Cluster complexity** | ⚠️⚠️⚠️⚠️⚠️ Critical | 超出 Lightweight 定位; Docker compose |
+| **SMB Oplocks integration** | ⚠️⚠️⚠️ Medium | RADOS locking API; careful design |
+

+
+## Alternatives (推荐方案)
+
+### 方案对比
+
+| 方案 | 跨平台 | 部署复杂度 | 定位匹配 | 状态 |
+|------|--------|-----------|---------|------|
+| **Ceph RADOS** | ❌ Linux-only | ⚠️⚠️⚠️⚠️⚠️ 极高 | ❌ 不匹配 | 搁置 |
+| **Ceph RGW (S3)** | ✅ HTTP API | ⚠️⚠️⚠️⚠️ 高 | ⭐⭐⭐ 中等 | 已有 S3Vfs |
+| **MinIO** | ✅ 全平台 | ⚠️⚠️ 低 | ⭐⭐⭐⭐⭐ 完全匹配 | 已有 S3Vfs |
+| **GlusterFS** | ✅ POSIX | ⚠️⚠️⚠️ 中 | ⭐⭐⭐⭐ 高 | 待研究 |
+| **内置分布式** | ✅ 全平台 | ⚠️⚠️ 低 | ⭐⭐⭐⭐⭐ 完全匹配 | 已有基础 |
+
+### 方案 1: MinIO (推荐)
+
+**优势**:
+- ✅ S3-compatible API（已有 S3Vfs，无需新代码）
+- ✅ 单节点部署（轻量级）
+- ✅ 跨平台（macOS/Linux/Windows）
+- ✅ 高性能（纠删码）
+- ✅ 开源 + 企业版
+
+**部署**:
+```bash
+# macOS 单节点
+minio server /data --console-address ":9001"
+
+# MarkBase 配置
+MB_S3_ENDPOINT=http://localhost:9000
+MB_S3_BUCKET=markbase
+```
+
+**集成**: 无需修改代码，S3Vfs 已支持。
+
+---
+
+### 方案 2: 内置分布式存储
+
+**已有基础**:
+| 功能 | 文件 | 分布式潜力 |
+|------|------|-----------|
+| DedupFs | dedup.rs | ✅ SHA-256 块存储可跨节点共享 |
+| RaidFs | raid.rs | ⚠️ 单节点 RAID-Z |
+| Send-Receive | send_receive.rs | ⚠️ 类似 ZFS send/receive |
+| Checksum | checksum.rs | ✅ 数据完整性验证 |
+| Compression | compression.rs | ✅ ZSTD 压缩 |
+
+**扩展方向**:
+1. DedupFs + S3Vfs: Dedup 块存储到 MinIO/S3（跨节点共享）
+2. Checksum + Replication: 增加跨节点复制
+3. Send-Receive + Remote: 增加远程 replication

+## Open Questions
+
+1. **部署目标**: Linux-only production vs macOS development?
+2. **Backend choice**: RADOS (librados) vs RGW (S3 API)?
+3. **Pool strategy**: Pool-per-share vs single pool + path prefix?

+# DedupFs + S3Vfs Combination Design
+
+**Date**: 2026-06-25
+**Status**: Design proposal
+**Goal**: Distributed deduplication storage via MinIO/S3 backend
+
+---
+
+## Executive Summary
+
+### Current State
+
+**DedupStore**（`dedup.rs`, 224 行）：
+- 基于**本地文件系统**的 dedup 存储
+- SHA-256 块哈希 + 引用计数
+- 块存储到本地目录（`store_path/.dedup/`）
+
+**问题**：
+- ❌ 无法跨节点共享 dedup 块
+- ❌ 无分布式容错能力
+- ❌ 单节点存储限制
+
+### Proposed Solution
+
+**DedupS3Store**：
+- 块存储到 **MinIO/S3** 对象（跨节点共享）
+- 引用计数存储到 S3 object metadata
+- Manifest 存储到 S3 对象（JSON 格式）
+
+**优势**：
+- ✅ 跨节点 dedup 共享（MinIO 分布式）
+- ✅ 自动容错（MinIO erasure coding）
+- ✅ 无单节点限制（MinIO 可扩展）
+- ✅ 与现有 S3Vfs 集成（无需新 HTTP API）

+### DedupS3Store Struct

+```rust
+pub struct DedupS3Store {
+    s3vfs: S3Vfs,                  // S3 backend
+    bucket: String,                // Bucket name (markbase-dedup)

+
+### Core Methods
+
+| Method | Current (LocalFs) | Proposed (S3Vfs) |
+|--------|------------------|------------------|
+| `store_block(data)` | `std::fs::write(store_path/hash, data)` | `S3Vfs.put_object(blocks/hash, data)` |
+| `get_block(hash)` | `std::fs::read(store_path/hash)` | `S3Vfs.get_object(blocks/hash)` |
+| `increment_ref(hash)` | `std::fs::write(hash.ref, count)` | `S3Vfs.put_object(blocks/hash, data) + metadata update` |
+| `decrement_ref(hash)` | `std::fs::write/remove` | `S3Vfs.delete_object + metadata check` |

+
+---
+
+## Reference Count Management
+
+### Challenge
+
+S3 对象不支持 atomic increment/decrement 操作。
+
+### Solution 1: Metadata Update (推荐 ⭐⭐⭐⭐⭐)
+
+**流程**：
+```rust
+fn increment_ref(&self, hash: &str) -> Result<(), VfsError> {
+    // 1. GET current metadata
+    let head = self.s3vfs.head_object(&format!("blocks/{}", hash))?;
+    let current_ref = head.metadata.get("x-amz-meta-ref-count")
+        .and_then(|v| v.parse::<u64>().ok())
+        .unwrap_or(0);
+    
+    // 2. PUT with updated metadata
+    let block_data = self.s3vfs.get_object(&format!("blocks/{}", hash))?;
+    self.s3vfs.put_object_with_metadata(
+        &format!("blocks/{}", hash),
+        &block_data,
+        [("x-amz-meta-ref-count", (current_ref + 1).to_string())]
+    )?;
+    
+    Ok(())
+}
+```
+
+**优势**：
+- ✅ 简单实现
+- ✅ 与 S3 标准兼容
+- ⚠️ 需要两次请求（GET + PUT）
+
+**劣势**：
+- ⚠️ 非原子操作（并发问题）
+- ⚠️ 需要读取块数据（PUT 需要 body）
+
+---
+
+### Solution 2: Separate Ref Count Object
+
+**流程**：
+```rust
+fn increment_ref(&self, hash: &str) -> Result<(), VfsError> {
+    // 1. GET ref count object
+    let ref_key = format!("refs/{}/count", hash);
+    let current = self.s3vfs.get_object(&ref_key)
+        .and_then(|data| data.parse::<u64>())
+        .unwrap_or(0);
+    
+    // 2. PUT updated ref count
+    self.s3vfs.put_object(&ref_key, (current + 1).to_string())?;
+    Ok(())
+}
+```
+
+**优势**：
+- ✅ 无需读取块数据
+- ✅ 更小的对象（仅数字）
+
+**劣势**：
+- ⚠️ 需要额外对象存储
+- ⚠️ 非原子操作（并发问题）
+
+---
+
+### Solution 3: MinIO Extended API (企业版)
+
+MinIO 企业版提供 `mc admin bucket policy` 和 object locking API。
+
+**优势**：
+- ✅ 可能提供 atomic operation
+
+**劣势**：
+- ⚠️ 仅 MinIO 企业版
+- ⚠️ 需要研究具体 API
+
+---
+
+## Concurrency Problem
+
+### Scenario
+
+Node A 和 Node B 同时 dedup 相同文件：
+1. Node A: `increment_ref(hash-abc)` → GET count=2 → PUT count=3
+2. Node B: `increment_ref(hash-abc)` → GET count=2 → PUT count=3
+3. 结果：count=3（错误，应为 count=4）
+
+### Solution 1: Optimistic Locking
+
+使用 S3 versioning 检测冲突：
+```rust
+fn increment_ref(&self, hash: &str) -> Result<(), VfsError> {
+    loop {
+        // 1. GET current version + metadata
+        let (version_id, current_ref) = self.get_ref_with_version(hash)?;
+        
+        // 2. PUT with version check
+        let result = self.s3vfs.put_object_if_version(
+            &format!("blocks/{}", hash),
+            block_data,
+            (current_ref + 1),
+            version_id  // Only succeed if version unchanged
+        );
+        
+        if result.is_ok() {
+            break;
+        }
+        // Retry if version mismatch
+    }
+    Ok(())
+}
+```
+
+**要求**：MinIO versioning enabled。
+
+---
+
+### Solution 2: Distributed Lock Service
+
+使用外部分布式锁（如 Redis/Zookeeper）：
+```rust
+fn increment_ref(&self, hash: &str) -> Result<(), VfsError> {
+    // 1. Acquire distributed lock
+    let lock = self.lock_service.acquire(&format!("lock:{}", hash))?;
+    
+    // 2. Increment ref count
+    self.update_ref_count(hash)?;
+    
+    // 3. Release lock
+    lock.release();
+    Ok(())
+}
+```
+
+**劣势**：需要额外服务（Redis）。
+
+---
+
+### Solution 3: Accept Non-Atomic (简化方案)
+
+对于 MarkBase Lightweight 定位：
+- ⚠️ 接受非原子操作风险
+- ⚠️ 偶尔 ref count 不准确（不影响数据完整性）
+- ⚠️ 定期修复（scrub job）
+
+**推荐**：Phase 1 使用 Solution 1（Metadata Update），Phase 2 研究 MinIO versioning。
+

+
+## Integration with MarkBase VFS
+
+### Option 1: Standalone DedupS3Store
+
+用户手动创建 DedupS3Store：
+```bash
+# CLI tool
+markbase dedup-upload --s3 --s3-endpoint http://localhost:9000 --file /data/large.iso
+markbase dedup-download --s3 --manifest-id <uuid> --output /data/restored.iso
+```
+
+---
+
+### Option 2: DedupVfsBackend (VfsBackend trait)
+
+创建 VfsBackend wrapper，自动 dedup：
+```rust
+pub struct DedupS3Backend {
+    dedup_store: DedupS3Store,
+    manifest_dir: PathBuf,  // Local cache for manifests
+}
+
+impl VfsBackend for DedupS3Backend {
+    fn open_file(&self, path: &Path, flags: &OpenFlags) -> Result<Box<dyn VfsFile>, VfsError> {
+        // 1. Read manifest from S3
+        let manifest = self.load_manifest(path)?;
+        
+        // 2. DedupS3File (read blocks from S3)
+        Ok(Box::new(DedupS3File::new(self.dedup_store.clone(), manifest)))
+    }
+    
+    fn stat(&self, path: &Path) -> Result<VfsStat, VfsError> {
+        // Read from manifest metadata
+        let manifest = self.load_manifest(path)?;
+        Ok(VfsStat {
+            size: manifest.original_size,
+            mtime: manifest.mtime,
+            ...
+        })
+    }
+    
+    fn read_dir(&self, path: &Path) -> Result<Vec<VfsDirEntry>, VfsError> {
+        // List manifests from S3
+        self.dedup_store.s3vfs.list_objects(&self.manifest_prefix)
+    }
+}
+```
+
+**优势**：
+- ✅ 透明 dedup（用户无需关心）
+- ✅ 与 SMB/WebDAV/SFTP 无缝集成
+
+---
+
+### Option 3: Hybrid (LocalFs + DedupS3Store)
+
+```rust
+pub struct HybridDedupBackend {
+    local: LocalFs,               // Small files (<1MB) 存本地
+    dedup_s3: DedupS3Store,       // Large files (>1MB) dedup to S3
+}
+
+impl VfsBackend for HybridDedupBackend {
+    fn open_file(&self, path: &Path, flags: &OpenFlags) -> Result<Box<dyn VfsFile>, VfsError> {
+        // Check file size
+        let stat = self.local.stat(path)?;
+        
+        if stat.size < self.dedup_s3.config.min_file_size {
+            // Small file: direct LocalFs
+            self.local.open_file(path, flags)
+        } else {
+            // Large file: dedup to S3
+            self.dedup_s3.dedup_file(path)?;
+            self.dedup_s3.open_file_from_manifest(path)
+        }
+    }
+}
+```
+
+**推荐**：Option 1（Phase 1），Option 3（Phase 2）。
+
+---
+
+## Performance Considerations
+
+### Network Latency
+
+| Operation | LocalFs | S3Vfs | Overhead |
+|-----------|---------|-------|----------|
+| store_block (4KB) | ~0.1ms | ~5-10ms (HTTP) | ~50-100x |
+| get_block (4KB) | ~0.1ms | ~5-10ms (HTTP) | ~50-100x |
+| dedup_file (100MB) | ~2s (25MB/s) | ~10s (10MB/s) | ~5x |
+
+**缓解方案**：
+- ✅ Async concurrent upload（4-8 并发）
+- ✅ ReadCache（64MB cache）
+- ✅ Local cache for hot blocks
+
+---
+
+### Dedup Ratio Impact
+
+| File Type | Dedup Ratio | Network Traffic Saved |
+|-----------|-------------|----------------------|
+| VM images (similar OS) | ~80% | -80% upload bandwidth |
+| Log files (daily) | ~60% | -60% upload bandwidth |
+| Unique files (photos) | ~5% | -5% upload bandwidth |
+
+---
+
+## Next Steps
+
+1. **Phase 1 Implementation** (~300 lines)
+   - `DedupS3Store` struct
+   - `store_block()` / `get_block()` via S3Vfs
+   - `increment_ref()` with metadata update
+
+2. **Phase 2 CLI Integration** (~100 lines)
+   - `markbase dedup-upload --s3`
+   - `markbase dedup-download --manifest-id`
+
+3. **Phase 3 Performance Test**
+   - Benchmark dedup_file (100MB)
+   - Compare LocalFs vs S3Vfs
+
+---
+
+## Open Questions
+
+1. **Concurrency**: Accept non-atomic ref count vs implement versioning?
+2. **Backend choice**: Standalone CLI vs VfsBackend integration?
+3. **Min versioning**: Should we require MinIO versioning enabled?
+4. **Ref count object**: Metadata vs separate object?
+5. **Block cache**: Should we cache blocks locally?

+| 问题 | 严重程度 | 影响 |
+|------|----------|------|
+| **Share Management 内存存储** | ⚠️⚠️⚠️⚠️⚠️ 极高 | 重启丢失所有共享配置 |
+| **Service Status 硬编码** | ⚠️⚠️⚠️⚠️ 高 | 无法反映真实服务状态 |
+| **Recent Activity 硬编码** | ⚠️⚠️⚠️⚠️ 高 | 无法查看真实操作记录 |
+| **Quick Actions 未实现** | ⚠️⚠️⚠️ 中 | 用户体验不完整 |
+| **无权限管理** | ⚠️⚠️⚠️⚠️ 高 | 无法控制用户访问权限 |
+
+---
+
+### 3.2 详细分析
+
+#### 问题 #1: Share Management 内存存储
+
+**当前实现**：
+```rust
+lazy_static::lazy_static! {
+    static ref SHARES: Arc<Mutex<Vec<ShareInfo>>> = 
+        Arc::new(Mutex::new(Vec::new()));
+}
+```
+
+**问题影响**：
+- 服务器重启后，所有共享配置丢失
+- 无法持久化到数据库或配置文件
+- 不符合生产环境要求
+
+**推荐方案**：
+- 使用 SQLite 存储（`data/shares.sqlite`）
+- 或 TOML 配置文件（`config/shares.toml`）
+
+---
+
+#### 问题 #2: Service Status 硬编码
+
+**当前实现**：
+```rust
+pub async fn get_all_services_status() -> Result<Vec<ServiceStatus>, String> {
+    Ok(vec![
+        ServiceStatus {
+            name: "SMB Server".to_string(),
+            status: "running".to_string(),
+            port: 4445,
+            uptime: "2h 30m".to_string(),
+        },
+        // ... 固定返回 4 个服务
+    ])
+}
+```
+
+**问题影响**：
+- 无法检测服务真实状态（running/stopped）
+- 无法获取真实 uptime
+- 无法监控服务异常
+
+**推荐方案**：
+- 使用 `ps aux | grep` 检查进程状态
+- 或使用 PID 文件追踪服务
+- 或使用 systemd/launchd 服务管理
+
+---
+
+#### 问题 #3: Recent Activity 硬编码
+
+**当前实现**：
+```rust
+pub async fn get_recent_activity() -> Result<Vec<ActivityLog>, String> {
+    Ok(vec![
+        ActivityLog {
+            timestamp: "2026-06-23 14:30:00".to_string(),
+            activity_type: "Upload".to_string(),
+            description: "Uploaded document.pdf to /data/files".to_string(),
+            user: "alice".to_string(),
+        },
+        // ... 固定返回 4 条记录
+    ])
+}
+```
+
+**问题影响**：
+- 无法查看真实用户操作
+- 无法审计系统行为
+- 无法追踪异常事件
+
+**推荐方案**：
+- 使用日志文件（`data/activity.log`）
+- 或 SQLite 存储（`data/activity.sqlite`）
+- 集成现有 SSH/SMB/WebDAV 日志
+
+---
+
+#### 问题 #4: Quick Actions 未实现
+
+**当前实现**：
+```vue
+<el-button type="primary" :icon="Upload" class="action-btn">
+  Upload File
+</el-button>
+<el-button type="success" :icon="Document" class="action-btn">
+  Create Backup
+</el-button>
+// ... 只有按钮，无 @click handler
+```
+
+**问题影响**：
+- 用户点击按钮无响应
+- Dashboard 功能不完整
+
+**推荐方案**：
+- Upload File: 调用 Tauri dialog + file_ops.rs
+- Create Backup: 调用 backup.rs snapshot 功能
+- View Backups: 跳转到 Backup.vue
+- Download File: 调用 Tauri dialog + file_ops.rs
+
+---
+
+#### 问题 #5: 无权限管理
+
+**当前实现**：
+- User Management 只有 CRUD 用户
+- Share Management 只有 CRUD 共享
+- **缺失**：用户-共享权限关联
+
+**问题影响**：
+- 无法控制用户访问哪些共享
+- 无法设置读/写权限
+- 无法实现多租户隔离
+
+**推荐方案**：
+- 添加 Permission Management 页面
+- 用户-共享关联表（user_id, share_id, permission）
+- 权限类型：read/write/admin

+
+## MarkBase S3Vfs Integration
+
+### 配置方式
+
+**环境变量**：
+```bash
+export MB_S3_ENDPOINT=http://localhost:9000
+export MB_S3_REGION=us-east-1
+export MB_S3_BUCKET=markbase
+export MB_S3_ACCESS_KEY=minioadmin
+export MB_S3_SECRET_KEY=minioadmin
+```
+
+**配置文件**（`config/s3.toml`）：
+```toml
+[s3]
+enabled = true
+endpoint = "http://localhost:9000"
+region = "us-east-1"
+bucket = "markbase"
+access_key = "minioadmin"
+secret_key = "minioadmin"
+
+[s3.webdav]
+# WebDAV 使用 S3 后端
+enabled = true
+user = "demo"
+root_prefix = "webdav/"
+```
+
+### S3Vfs 使用示例
+
+**WebDAV + MinIO**：
+```bash
+# 启动 WebDAV server（使用 MinIO 后端）
+cargo run -- webdav-start \
+  --user demo \
+  --port 8002 \
+  --s3 \
+  --s3-endpoint http://localhost:9000 \
+  --s3-bucket markbase \
+  --s3-access-key minioadmin \
+  --s3-secret-key minioadmin \
+  --s3-region us-east-1 \
+  --root webdav/
+```
+
+**SMB + MinIO**（通过 VFS backend）：
+```bash
+# 启动 SMB server（使用 MinIO 后端）
+cargo run --features smb-server -- smb-start \
+  --port 4445 \
+  --share-name files \
+  --s3 \
+  --s3-endpoint http://localhost:9000 \
+  --s3-bucket markbase \
+  --s3-access-key minioadmin \
+  --s3-secret-key minioadmin \
+  --s3-region us-east-1 \
+  --root smb/
+```
+
+---
+
+## MinIO Bucket Management
+
+### 创建 Bucket
+
+```bash
+# 使用 MinIO client (mc)
+mc alias set myminio http://localhost:9000 minioadmin minioadmin
+mc mb myminio/markbase
+
+# 使用 AWS CLI
+aws --endpoint-url http://localhost:9000 s3 mb s3://markbase
+```
+
+### 设置 Bucket Policy
+
+```bash
+# 公开读取 policy（用于 public shares）
+mc anonymous set download myminio/markbase/public
+
+# 私有 policy（默认）
+mc anonymous set none myminio/markbase/private
+```
+
+### 设置 Bucket Quota
+
+```bash
+# 设置 quota（MinIO 企业版功能）
+mc admin bucket quota myminio/markbase 10GB
+```
+
+---
+
+## MinIO Features Relevant to MarkBase
+
+| Feature | Description | MarkBase Use Case |
+|---------|-------------|-------------------|
+| **Erasure Coding** | 数据冗余（默认 EC:2） | 自动容错，类似 RAID |
+| **Versioning** | 对象版本控制 | 可替代 Snapshot 功能 |
+| **Bucket Policy** | ACL 管理 | 用户权限控制 |
+| **Lifecycle Rules** | 自动过期 | 旧 backup 清理 |
+| **Object Lock** | WORM 模式 | 合规性备份保护 |
+| **Replication** | 跨站点复制 | Disaster recovery |
+
+### Versioning（替代 Snapshot）
+
+```bash
+# 启用 versioning
+mc version enable myminio/markbase
+
+# 列出对象版本
+mc ls --versions myminio/markbase/file.txt
+
+# 恢复旧版本
+mc cp myminio/markbase/file.txt#version-id myminio/markbase/file.txt
+```
+
+### Lifecycle Rules（Backup 清理）
+
+```bash
+# 设置 30 天后自动删除
+mc ilm add myminio/markbase --expire-days 30
+```
+
+---
+
+## Performance Optimization
+
+### MinIO 性能参数
+
+```bash
+# 高性能配置
+minio server /data \
+  --console-address ":9001" \
+  --parallel 8 \
+  --cache /cache:1000
+```
+
+### S3Vfs 性能优化
+
+**并发上传**（已在 S3Vfs 实现）：
+- Multipart upload（大于 5MB 自动分片）
+- 并发上传分片（默认 4 并发）
+
+**缓存**：
+- ReadCache: 64MB, 64KB blocks, 5min TTL（已在 cache.rs 实现）
+- WriteCache: 32MB（已在 cache.rs 实现）
+
+---
+
+## Docker Compose Example
+
+```yaml
+version: '3'
+services:
+  minio:
+    image: minio/minio:latest
+    command: server /data --console-address ":9001"
+    ports:
+      - "9000:9000"
+      - "9001:9001"
+    volumes:
+      - minio-data:/data
+    environment:
+      - MINIO_ROOT_USER=minioadmin
+      - MINIO_ROOT_PASSWORD=minioadmin
+
+  markbase-webdav:
+    build: .
+    command: webdav-start --user demo --port 8002 --s3 --s3-endpoint http://minio:9000 --s3-bucket markbase --s3-access-key minioadmin --s3-secret-key minioadmin
+    ports:
+      - "8002:8002"
+    environment:
+      - MB_S3_ENDPOINT=http://minio:9000
+    depends_on:
+      - minio
+
+volumes:
+  minio-data:
+```
+
+---
+

+## Troubleshooting
+
+### MinIO 连接问题
+
+```bash
+# 检查 MinIO status
+mc admin info myminio
+
+# 检查 endpoint 连接
+curl -I http://localhost:9000/minio/health/live
+```
+
+### S3Vfs 错误
+
+**常见错误**：
+- `VfsError::NotFound` → Bucket 或 object 不存在
+- `VfsError::PermissionDenied` → Access key/secret key 错误
+- `VfsError::Io("S3 PUT failed: 403")` → Bucket policy 拒绝写入
+
+**调试方法**：
+```bash
+# 查看 MinIO logs
+docker logs minio
+
+# 使用 mc 测试
+mc cp test.txt myminio/markbase/test.txt
+mc ls myminio/markbase/
+```
+
+---
+
+## MinIO vs S3Vfs Feature Mapping

+| VfsBackend Method | MinIO S3 API | Status |
+|-------------------|--------------|--------|
+| `read_dir()` | ListObjectsV2 | ✅ |
+| `open_file()` | GetObject / PutObject | ✅ |
+| `stat()` | HeadObject | ✅ |
+| `create_dir()` | PutObject (0-byte) | ✅ |
+| `remove_dir()` | DeleteObject | ✅ |
+| `remove_file()` | DeleteObject | ✅ |
+| `rename()` | CopyObject + DeleteObject | ✅ |
+| `exists()` | HeadObject | ✅ |
+| `copy()` | CopyObject | ✅ |
+| `hard_link()` | CopyObject | ✅ |
+| `create_snapshot()` | Versioning | ⚠️ 需启用 versioning |
+| `list_snapshots()` | ListObjectVersions | ⚠️ 需实现 |
+| `set_quota()` | Bucket quota | ⚠️ MinIO 企业版 |
+| `set_acl()` | Bucket policy | ⚠️ 需实现 |
+
+---
+
+## Next Steps
+
+1. **部署 MinIO**（用户 action）
+   - macOS: `brew install minio && minio server /data`
+   - Docker: `docker run minio/minio server /data`
+
+2. **创建 Bucket**（用户 action）
+   - `mc alias set myminio http://localhost:9000 minioadmin minioadmin`
+   - `mc mb myminio/markbase`
+
+3. **配置 MarkBase**
+   - 设置 `MB_S3_*` 环境变量
+   - 或使用 CLI 参数 `--s3 --s3-endpoint ...`
+
+4. **测试连接**
+   - WebDAV: `curl -X PROPFIND http://localhost:8002/webdav/`
+   - SMB: `smbclient -p 4445 -L localhost`
