+# Consul 持久化存储修复方案
+
+## 🚨 问题诊断
+
+**根本原因：你的 Consul 集群确实没有配置持久化存储！**
+
+### 当前问题：
+1. **数据目录** `/opt/nomad/data/consul` 只是容器内临时目录
+2. **没有 volume 挂载** - 重启后数据完全丢失
+3. **缺少 onecloud1 节点** - 配置与实际运行状态不一致
+
+### 影响：
+- ✅ **Consul 服务发现正常** - 这部分数据在内存中
+- ❌ **KV 存储数据丢失** - 所有配置、tokens、证书都没了
+- ❌ **ACL 配置丢失** - 权限设置重置
+- ❌ **服务配置丢失** - 注册的服务元数据丢失
+
+## 🔧 修复方案
+
+### 第一步：配置持久化存储
+
+**在每个 Consul 节点上运行：**
+```bash
+# 在 ch4, ash3c, warden 节点上分别执行
+./scripts/setup-consul-persistent-storage.sh
+```
+
+**这个脚本会：**
+1. 创建 `/opt/consul/data` 目录
+2. 设置正确的权限 (nomad:nomad)
+3. 在 Nomad 配置中添加 host volume
+4. 重启 Nomad 客户端
+
+### 第二步：部署持久化 Consul
+
+**停止当前 job：**
+```bash
+nomad job stop consul-cluster-nomad
+```
+
+**部署新配置：**
+```bash
+nomad job run infrastructure/nomad/nomad-jobs/consul-cluster/consul-cluster-persistent.nomad
+```
+
+### 第三步：恢复数据
+
+**如果有备份数据：**
+```bash
+# 从 Consul KV 备份恢复
+consul kv import @backup.json
+
+# 或从快照恢复
+consul snapshot restore backup.snap
+```
+
+**如果没有备份：**
+- 需要重新配置所有 KV 数据
+- 重新设置 Cloudflare tokens
+- 重新注册服务
+
+## 🎯 新配置的优势
+
+### 持久化存储：
+- **Host Volume** - 数据存储在宿主机 `/opt/consul/data`
+- **重启安全** - 重启 job 不会丢失数据
+- **跨 allocation** - 数据在 allocation 之间保持
+
+### 改进配置：
+- **统一 bootstrap-expect=3** - 所有节点都知道集群大小
+- **健康检查** - 自动监控服务状态
+- **日志级别** - 便于调试
+- **服务注册** - 自动注册到 Consul
+
+## 📋 执行清单
+
+### 准备阶段：
+- [ ] 备份当前 KV 数据 (如果还有)
+- [ ] 记录当前服务注册状态
+- [ ] 准备重新配置的数据
+
+### 执行阶段：
+- [ ] 在 ch4 节点运行存储配置脚本
+- [ ] 在 ash3c 节点运行存储配置脚本  
+- [ ] 在 warden 节点运行存储配置脚本
+- [ ] 停止当前 Consul job
+- [ ] 部署持久化 Consul job
+- [ ] 验证集群状态
+
+### 验证阶段：
+- [ ] 检查 Consul 集群状态
+- [ ] 验证 leader 选举
+- [ ] 测试 KV 存储
+- [ ] 恢复关键配置数据
+
+## 🚨 重要提醒
+
+**这是一个严重的架构缺陷！**
+- 生产环境的 Consul 集群没有持久化存储是不可接受的
+- 这相当于把银行的金库建在沙滩上
+- 必须立即修复，否则随时可能再次丢失数据
+
+**修复后的好处：**
+- 真正的高可用 Consul 集群
+- 数据持久化保证
+- 符合生产环境标准
+- 可以安全地重启和维护
