|
||||
|
||||
## 部署步骤
|
||||
|
||||
### 1. 安装依赖
|
||||
|
||||
```bash
|
||||
sudo apt update
|
||||
sudo apt install mdadm fio sysstat nvme-cli tgt
|
||||
```
|
||||
|
||||
### 2. 检查NVMe磁盘
|
||||
|
||||
```bash
|
||||
nvme list
|
||||
nvme smart-log /dev/nvme0n1
|
||||
```
|
||||
|
||||
### 3. 创建RAID 0阵列
|
||||
|
||||
```bash
|
||||
sudo bash scripts/deploy_raid0_linux.sh
|
||||
```
|
||||
|
||||
**关键参数：**
|
||||
- Stripe size: 64KB（适合媒体文件）
|
||||
- Filesystem: XFS（优化大文件）
|
||||
- Mount options: noatime, largeio
|
||||
|
||||
### 4. 性能测试
|
||||
|
||||
```bash
|
||||
sudo bash scripts/run_raid0_tests.sh
|
||||
```
|
||||
|
||||
**测试项目：**
|
||||
- Sequential read/write (最大频宽)
|
||||
- 4K video streaming (ProRes 4444)
|
||||
- Concurrent streams (多流并发)
|
||||
- IOPS saturation (最大IOPS)
|
||||
|
||||
## 性能结果
|
||||
|
||||
### 4盘RAID 0实测（预期）
|
||||
|
||||
|测试项目 |预期性能 |实测方法 |
|
||||
|---|---|---|
|
||||
|Sequential read |28 GB/s |fio bs=1M |
|
||||
|Sequential write |20 GB/s |fio bs=1M |
|
||||
|4K ProRes read |3200 MB/s (4 streams) |fio bs=256k |
|
||||
|Random IOPS |2400K |fio bs=4k |
|
||||
|
||||
### 瓶颈分析
|
||||
|
||||
**可能的瓶颈：**
|
||||
1. **PCIe带宽限制** - 每NVMe需要PCIe 4.0 × 4 lanes
|
||||
2. **CPU瓶颈** - RAID计算开销（检查top）
|
||||
3. **NUMA问题** - 多CPU节点内存访问
|
||||
4. **内核开销** - mdadm vs 用户态RAID
|
||||
|
||||
**优化方案：**
|
||||
- 确保每个NVMe有独立PCIe通道
|
||||
- 使用NUMA-aware配置（numactl）
|
||||
- 增加iodepth（fio测试）
|
||||
- 调整stripe size（32KB/64KB/128KB）
|
||||
|
||||
## MarkBase集成
|
||||
|
||||
### 方案1：本地挂载（最优）
|
||||
|
||||
```bash
|
||||
# Linux mount
|
||||
mount /dev/md0 /mnt/raid0_media
|
||||
|
||||
# MarkBase WebDAV backend
|
||||
cargo run -- display --backend /mnt/raid0_media
|
||||
```
|
||||
|
||||
**优势：**
|
||||
- 全速访问（28 GB/s）
|
||||
- 无网络延迟
|
||||
- 直接集成SQLite文件树
|
||||
|
||||
### 方案2：iSCSI导出（远程访问）
|
||||
|
||||
```bash
|
||||
# Linux: 配置iSCSI target
|
||||
sudo bash scripts/markbase_raid0_integration.sh
|
||||
|
||||
# macOS: 连接iSCSI initiator
|
||||
# xtend SAN iSCSI Initiator
|
||||
Discovery Portal: <SERVER_IP>:3260
|
||||
Target: iqn.2026-05.com.markbase:raid0.media
|
||||
```
|
||||
|
||||
**限制：**
|
||||
- 网络瓶颈（10GbE ≈ 1.25 GB/s）
|
||||
- 延迟增加（LAN < 1ms）
|
||||
- 需高速网络（25GbE+ for full speed）
|
||||
|
||||
### 方案3：NFS导出（文件级访问）
|
||||
|
||||
```bash
|
||||
# Linux NFS server
|
||||
apt install nfs-kernel-server
|
||||
echo "/mnt/raid0_media *(rw,sync,no_subtree_check)" >> /etc/exports
|
||||
exportfs -a
|
||||
|
||||
# macOS NFS client
|
||||
mount -t nfs <SERVER_IP>:/mnt/raid0_media /Volumes/MarkBase_NFS
|
||||
```
|
||||
|
||||
**性能：**
|
||||
- NFS v4: 800-1000 MB/s（1GbE）
|
||||
- NFS v4 + 10GbE: 2000-3000 MB/s
|
||||
|
||||
## 监控与维护
|
||||
|
||||
### RAID状态监控
|
||||
|
||||
```bash
|
||||
# 检查RAID状态
|
||||
mdadm --detail /dev/md0
|
||||
cat /proc/mdstat
|
||||
|
||||
# NVMe健康检查
|
||||
nvme smart-log /dev/nvme0n1 | grep percentage_used
|
||||
```
|
||||
|
||||
### 性能监控
|
||||
|
||||
```bash
|
||||
# 实时I/O监控
|
||||
iostat -x /dev/md0 1
|
||||
|
||||
# 带宽监控
|
||||
nethogs /dev/md0
|
||||
|
||||
# NVMe温度监控
|
||||
nvme get-feature -f 2 /dev/nvme0n1
|
||||
```
|
||||
|
||||
### 故障处理
|
||||
|
||||
**RAID 0风险：**
|
||||
- ❌ 无冗余（单盘故障 = 全盘数据丢失）
|
||||
- ❌ 不可恢复（无parity）
|
||||
|
||||
**防护措施：**
|
||||
- 定期备份（rsync到RAID 10阵列）
|
||||
- 监控NVMe健康（percentage_used）
|
||||
- 及时更换老化磁盘
|
||||
- 仅用于非关键数据（cache, scratch）
|
||||
|
||||
## 扩展方案
|
||||
|
||||
### 升级到RAID 10
|
||||
|
||||
```bash
|
||||
# RAID 10 (4盘)
|
||||
mdadm --create /dev/md10 \
|
||||
--level=10 \
|
||||
--raid-devices=4 \
|
||||
--layout=f2 \
|
||||
/dev/nvme[0-3]n1
|
||||
|
||||
# 性能：14 GB/s读，10 GB/s写，1200K IOPS
|
||||
# 容量：4TB (50%)
|
||||
# 可靠性：可承受2盘故障
|
||||
```
|
||||
|
||||
### 升级到RAID 5
|
||||
|
||||
```bash
|
||||
# RAID 5 (4盘)
|
||||
mdadm --create /dev/md5 \
|
||||
--level=5 \
|
||||
--raid-devices=4 \
|
||||
/dev/nvme[0-3]n1
|
||||
|
||||
# 性能：21 GB/s读，5 GB/s写，600K IOPS
|
||||
# 容量：6TB (75%)
|
||||
# 可靠性：可承受1盘故障
|
||||
```
|
||||
|
||||
## 成本估算
|
||||
|
||||
### 4盘RAID 0配置
|
||||
|
||||
|项目 |数量 |单价 |总价 |
|
||||
|---|---|---|---|
|
||||
|NVMe SSD |4 × 2TB |$179 |$716 |
|
||||
|Linux服务器 |- |- |$1500 |
|
||||
|10GbE网卡 |1 |$200 |$200 |
|
||||
|总计 |- |- |$2416 |
|
||||
|
||||
**性能/成本比：**
|
||||
- 28 GB/s读 / $2416 = 11.6 MB/s/$
|
||||
- 对比单盘：7000 MB/s / $179 = 38.9 MB/s/$
|
||||
- RAID 0成本效率：30%（因硬件重复）

|
||||
```bash
|
||||
# Backup critical data to RAID 10 array
|
||||
rsync -avh --progress /mnt/raid0_media/critical/ /mnt/raid10_backup/
|
||||
|
||||
# Or backup to external storage
|
||||
rsync -avh --progress /mnt/raid0_media/ /mnt/external_backup/
|
||||
```
|
||||
|
||||
### Monthly Health Check
|
||||
|
||||
```bash
|
||||
# Full disk health assessment
|
||||
nvme smart-log /dev/nvme0n1 > /var/log/nvme_health.log
|
||||
|
||||
# Check for:
|
||||
# - percentage_used (should be <20% after 1 year)
|
||||
# - media_errors (should be 0)
|
||||
# - num_err_log_entries (should be low)
|
||||
```
|
||||
|
||||
## Troubleshooting Guide
|
||||
|
||||
### Common Issues
|
||||
|
||||
|Issue |Symptom |Solution |
|
||||
|---|---|---|
|
||||
|Low performance |<15 GB/s read |Check PCIe lanes, NUMA config |
|
||||
|Disk failure |mdadm: Faulty |Replace disk immediately (RAID 0 data loss!) |
|
||||
|Mount failure |XFS error |Check filesystem: xfs_repair /dev/md0 |
|
||||
|iSCSI disconnect |Network timeout |Check NIC bonding, switch config |
|
||||
|
||||
### Emergency Procedures
|
||||
|
||||
**Disk Failure (RAID 0 Critical!)**
|
||||
```bash
|
||||
# RAID 0 has NO redundancy
|
||||
# Single disk failure = TOTAL DATA LOSS
|
||||
|
||||
# Immediate actions:
|
||||
# 1. Stop all I/O immediately
|
||||
# 2. Check if data recoverable from backup
|
||||
# 3. Replace failed disk
|
||||
# 4. Rebuild RAID 0 from backup
|
||||
# 5. Verify data integrity
|
||||
|
||||
# Prevention: Backup daily to RAID 10 array!
|
||||
```
|
||||
|
||||
**Performance Degradation**
|
||||
```bash
|
||||
# Check bottlenecks
|
||||
top # CPU usage
|
||||
iostat -x 1 # I/O queue
|
||||
numactl -H # NUMA topology
|
||||
|
||||
# Solutions:
|
||||
# - Increase iodepth (fio)
|
||||
# - Use NUMA-aware allocation
|
||||
# - Check PCIe bandwidth (lspci)
|
||||
```
|
||||
|

### 1. RAID 0实现（src/raid/level_0.rs）
|
||||
|
||||
**核心算法：**
|
||||
```rust
|
||||
fn locate_block(&self, block_offset: u64) -> (usize, u64) {
|
||||
let stripe_index = block_offset / self.array.stripe_size;
|
||||
let member_index = stripe_index % self.array.members.len() as u64;
|
||||
let member_offset = (stripe_index / self.array.members.len() as u64) * self.array.stripe_size;
|
||||
|
||||
(member_index as usize, member_offset)
|
||||
}
|
||||
```
|
||||
|
||||
**验证结果：**
|
||||
- ✅ Stripe分布正确（64KB chunks）
|
||||
- ✅ read/write功能正常
|
||||
- ✅ 3 disk测试通过（virtual environment）
|
||||
|
||||
**测试证明：**
|
||||
```
|
||||
cargo run --bin raid_stripe_test --release
|
||||
|
||||
结果：
|
||||
✅ RAID array created: raid_1779131792
|
||||
✅ Stripe size: 64KB (65536 bytes)

||||
✅ Test data: 197632 bytes (3 stripes + 1024 bytes)
|
||||
✅ Write successful
|
||||
✅ Read successful
|
||||
✅ Data integrity verified
|
||||
✅ All RAID 0 tests passed!

- 重写`locate_stripe_all_disks()`函数
|
||||
- 实现数据分割逻辑
|
||||
- 修复parity计算
|
||||
|
||||
**预计工作量：**
|
||||
- level_5.rs重写（150+ lines）
|
||||
- 测试验证（raid5_test.rs）
|
||||
|
||||
### 2. Linux服务器部署
|
||||
|
||||
**需求：**

|
||||
```
|
||||
|
||||
### 3. MarkBase + RAID集成
|
||||
|
||||
**架构方案：**
|
||||
|
||||
**方案A：本地挂载（推荐）**
|
||||
```
|
||||
┌─────────────────┐
|
||||
│ MarkBase │
|
||||
│ ├─ WebDAV │ ← Port 11438
|
||||
│ ├─ SQLite │ ← warren.sqlite
|
||||
│ └─ Backend │ ← /mnt/raid0_media (28 GB/s)
|
||||
└─────────────────┘
|
||||
↓
|
||||
┌─────────────────┐
|
||||
│ Linux RAID 0 │
|
||||
│ ├─ /dev/md0 │ ← 4 × NVMe
|
||||
│ └─ XFS fs │ ← 8TB, 64KB stripe
|
||||
└─────────────────┘
|
||||
```
|
||||
|
||||
**方案B：iSCSI远程访问**
|
||||
```
|
||||

|
||||
│ macOS Client │
|
||||
│ ├─ MarkBase │ ← Port 11438
|
||||
│ ├─ SQLite │ ← warren.sqlite
|
||||
│ └─ iSCSI mount │ ← /Volumes/MarkBase_RAID0
|
||||
└─────────────────┘
|
||||
↓ iSCSI (10GbE)
|
||||
┌─────────────────┐
|
||||
│ Linux Server │
|
||||
│ ├─ RAID 0 │ ← 28 GB/s (local)
|
||||
│ └─ iSCSI tgt │ ← 1.25 GB/s (network)
|
||||
└─────────────────┘
|
||||
```
|
||||
|
||||
**性能对比：**
|
||||

|
||||
|iSCSI (10GbE) |1.25 GB/s |<1ms |远程客户端 |
|
||||
|iSCSI (25GbE) |3.1 GB/s |<0.5ms |高速网络 |
|
||||
|
||||
### 4. 文件树同步机制
|
||||
|
||||
**需求：**
|
||||
- SQLite warren.sqlite（12658 nodes）
|
||||
- RAID 0物理存储映射
|
||||
- aliases_json.path解析
|
||||
- 实时同步更新
|
||||
|
||||
**实现计划：**
|
||||
```rust
|
||||
// 伪代码
|
||||
struct RaidBackend {
|
||||
raid_path: PathBuf, // /mnt/raid0_media
|
||||
sqlite_db: PathBuf, // warren.sqlite
|
||||
|
||||
fn resolve_node(node_id: &str) -> PathBuf {
|
||||
// 1. Query SQLite for aliases_json.path
|
||||
// 2. Parse path extraction
|
||||
// 3. Resolve relative to RAID mount
|
||||
// 4. Return physical path
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 风险评估
|
||||
|
||||
### RAID 0风险
|
||||
|
||||
|风险 |影响 |缓解措施 |
|
||||
|---|---|---|
|

- 使用场景：cache, scratch, 临时文件
|
||||
- 避免场景：关键数据（使用RAID 10/5）
|
||||
- 备份策略：rsync到RAID 10存储
|
||||
|
||||
### iSCSI风险
|
||||
|
||||
|风险 |影响 |缓解措施 |
|
||||
|---|---|---|
|
||||
|网络故障 |连接中断 |多网卡绑定 |
|
||||
|延迟增加 |性能下降 |25GbE+网络 |
|
||||
|带宽限制 |无法全速 |本地挂载优先 |
