概述
第一、环境
1、软件版本
CloudStack 3.0.5+XenServer 6.0.2
2、硬件设备
管理节点：DELL R420 10.30.18.2
计算节点：DELL R720 10.30.18.9
存储节点：DELL IBM520 10.30.18.4
3、网络环境
网段：10.30.18.0/24
网关：10.30.18.1
DNS：202.194.104.35
4、CloudStack规划
物理服务器网段： 10.30.18.2--10.30.18.15
管理网段： 10.30.18.16--10.30.18.24
来宾网段： 10.30.18.25--10.30.18.40
DNS： 8.8.8.8/8.8.4.4
存储类型： NFS
主存储： /export/primary1
辅助存储： /export/secondary
http服务器： 10.30.18.2
www目录： /var/www/html
5、故障原因及现象
1、硬件故障：计算节点R720内存问题导致非正常死机，并且不能正常启动
2、平台故障：排出了计算节点R720的硬件问题后，计算节点的状态是“error”
第二、处理流程
步骤一、首先备份cloud数据库
1.1登录管理节点10.30.18.2
[root@master ~]# hostname
master
[root@master ~]#
1.2查看当前的数据库列表
[root@master ~]# mysql -u root -p
Enter password:
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| cloud |
| cloud_usage |
| cloudbridge |
| glance |
| mysql |
| nova |
+--------------------+
7 rows in set (0.11 sec)
1.3备份cloud数据库
[root@master ~]# mysqldump -u root -p -A --event > ./db_all.20140426.sql
Enter password:
备注：-A 表示备份MySql中所有的数据库，恢复是需要先在MySql中新建数据库名。
步骤二、其次备份存储
2.1ssh登录存储：
[root@store ~]# hostname
store
[root@store ~]#
2.2备份主存储
[root@store ~]# cp -rpv /export/primary1/ /export/primary2
2.3备份服务存储
[root@store ~]# cp -rpv /export/secondary1/ /export/secondary2
步骤三、重建CloudStack环境
3.1先停止并删除在host下运行的实例VM
3.2禁用区域，并删除系统虚拟机（v,s,r）
3.4启用主存储的维护模式然后删除主存储 、二级存储
3.5启用主机host的维护模式然后删除host
3.6删除群集
3.7删除pod
3.8网络|来宾网络|删除
3.9区域|物理网络|删除
3.10删除区域
3.11清空NFS共享存储目录
#rm -rf /export/primary1/*
备注：原有的primary1目录数据已经备份到了primary2目录中
#rm -rf /export/secondary1/*
备注：原有的secondary1目录数据已经备份到了secondary2目录中
3.12停止CloudStack服务
3.13重新安装计算节点xenserver
3.14、删除CloudStack数据库
#drop database cloud; drop database cloud_usage;
3.15重新部署CS数据库
#cloud-setup-databases cloud:cloud@localhost --deploy-as=root:password
#cloud-setup-management
3.16安装系统模版（不同的hypervisor请安装不同的系统模版）
[root@management CloudStack-3.0.5-1-rhel6.2]# mount -t nfs 192.168.1.250:/storage/secondary /opt
[root@management CloudStack-3.0.5-1-rhel6.2]# /usr/lib64/cloud/agent/scripts/storage/secondary/cloud-install-sys-tmplt -m /opt -f /root/acton-systemvm-02062012.vhd.bz2 -h xenserver -F
[root@management ~]# umount /opt
3.17、启动cloud服务
#service cloud-management start
3.18、设置全局变量
Secstorage.allowed.internal.sites ：设置辅助存储的允许范围
Expunge.delay ：设置删除的延时
Expunge.interval ：设置删除的时间间隔
Cpu.overprovisioning.factor ：设置CPU超分
Mem.overprovisioning.factor ：设置内存超分（3.0.5版本无效）
重启cloud-management服务：
#service cloud-management restart
步骤四、创建基本资源域环境
备注：此处不是重点，故此略过
步骤五、原有的数据结构
5.1进入msyql数据库
[root@master ~]# mysql -u root -p
Enter password:

5.2切换到cloud数据库
mysql> use cloud;

You can turn off this feature to get a quicker startup with -A
Database changed
5.3查看cloud数据库的表

步骤六、导出模板
备注1：导出的vhd模板文件可以在CloudStack环境中通过“上传模板”进行导入
备注2：以From-Xen-29模板导出为例，其它模板的导出同样操作
6.1进入mysql数据库
[root@master ~]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or g.
Your MySQL connection id is 135

mysql> use cloud;

Database changed
mysql>
6.2查看"From-Xen-29"模板的存放路径
mysql> select id from vm_template where name="From-Xen-29"; #得到id=202
+-----+
| id |
+-----+
| 203 |
+-----+
备注：此处的203就是模板“From-Xen-29”模板在二级存储目录中的路径“.../template/tmpl/203”
mysql> select install_path from template_host_ref where template_id="203" and destroyed="0"; #得到vhd文件
+----------------------------------------------------------------+
| install_path |
+----------------------------------------------------------------+
| template/tmpl//2/203//e872d515-2858-33a8-802a-a4bd89c4b7fb.vhd |
+----------------------------------------------------------------+
1 row in set (0.00 sec)
6.3查看二级存储中模板(template)目录结构
备注：数据库得到的id=203和目录结构中的203目录是对应的。

8 directories, 12 files
6.4查看vhd模板文件的大小
[root@store export]# du -h /export/secondary2/template/tmpl/2/203/e872d515-2858-33a8-802a-a4bd89c4b7fb.vhd
3.1G /export/secondary2/template/tmpl/2/203/e872d515-2858-33a8-802a-a4bd89c4b7fb.vhd
6.5查看vhd模板文件的说明概述文件
[root@store export]# cat /export/secondary2/template/tmpl/2/203/template.properties
#

hvm=true
description=

6.6复制模板vhd文件
/export/secondary2/template/tmpl/2/203/e872d515-2858-33a8-802a-a4bd89c4b7fb.vhd
步骤七、导出数据卷（未成功）
说明：此处我们导出的数据卷的容量大小明显和我们需要导出的vhd卷文件不匹配，可能原因是由于数据磁盘附加到了vm虚拟机上，CloudStack会不断的更新数据磁盘
备注1：以From-Xen-30-E数据卷的导出为例
特别注意：此处我们主要的是导出数据卷，而不是ROOT根卷，因为发生故障时ROOT卷一般都不正常，即使导出了也不能用
而ROOT卷的数据，我们通过之前的模板导出来恢复

7.2查看”volumes”表中 name="From-Xen-30-E"并且state="ready"的记录中path和folder
mysql> select path,folder from volumes where state="ready" and name="From-Xen-30-E" G;
*************************** 1. row ***************************
path: 61aab5bc-0194-494b-a2b6-bbbc6fc80abc
folder: /export/primary1
1 row in set (0.00 sec)
备注：根据folder的值可以知道卷文件的保存位置在主存储中，根据path确定vhd文件的名称
7.3查看主存储的结构

4.4M /export/primary2/61aab5bc-0194-494b-a2b6-bbbc6fc80abc.vhd
备注：CloudStack正常时尝试，vhd的大小不正常。这个可能是由于数据磁盘已经附加在了vm虚拟机上
步骤八、导出快照
备注1：导出的vhd快照文件可以在CloudStack环境中进行导入，类型不同导入方法不同：
DATA快照：通过“上载卷”导入
ROOT快照：通过“上传模板”导入
备注2：以导出”From-Xen-29”的根ROOT卷的快照为例

8.2查看有效的快照信息

备注：该环境中我们只为每个卷做个一个快照
mysql> select name,backup_snap_id from snapshots where status="backedup" G;

备注：”.../snapshots/2/25/0ae4c760-04ad-4e98-9434-3f6194b734e6.vhd”是我们要导出的vhd文件。
8.4查看”From-Xen-29”的ROOT卷快照的大小
[root@store export]# du -h /export/secondary2/snapshots/2/25/0ae4c760-04ad-4e98-9434-3f6194b734e6.vhd
3.6G /export/secondary2/snapshots/2/25/0ae4c760-04ad-4e98-9434-3f6194b734e6.vhd
8.5复制vhd快照文件
/export/secondary2/snapshots/2/25/0ae4c760-04ad-4e98-9434-3f6194b734e6.vhd
特别说明：
CloudStack导出打vhd文件，并不能通过XenCenter导入到XenServer中。具体原因未知
