昨天晚上去机房为数据库服务器做磁盘扩容，顺带为目前线上的存储系统MooseFS做了一次灾难演练。故此，今天准备把昨天的灾难演练的详情总结一下，分享给大家。如果大家正在使用MooseFS，那么就可以有所参考了。
MooseFS是一个分布式的文件系统，有关它的具体信息，我这里就不多做介绍了，大家可以去参考我之前写过的三篇博文：
分布式文件系统之MooseFS----介绍
分布式文件系统之MooseFS----部署
分布式文件系统之MooseFS----管理优化
这里简单先介绍一下，目前我们这套存储的架构设计：
服务器的配置情况：
mfsmaster主和mfsmaster备
品牌：Dell PowerEdge R720
CPU：Intel(R) Xeon(R) CPU E5-2630 v2 @ 2.60GHz
内存：8 * 8G
磁盘：300G * 6
RAID级别：10
mfschunkserver
品牌：Dell PowerEdge R720
CPU：Intel(R) Xeon(R) CPU E5-2630 v2 @ 2.60GHz
内存：4 * 8G
磁盘：2T * 6
RAID级别：10
架构介绍：
整个MooseFS的架构，是以两台mfsmaster，一台主，一台备，中间heartbeat+drbd技术来做该服务的高可用，后端放置3台存储节点，负责提供数据存储服务。
灾难演练计划：
本次灾难演练主要从几个会触发故障的因素出发，采用人工模拟故障的方式来真实触发故障，然后记录故障发生前后相关服务的状态，相关服务的日志记录和故障发生前后客户端的服务使用情况等，然后通过分析记录的信息来判断服务的高可用性是否OK。
几个记录点的目标：
通过记录故障发生前后的服务状态来判断服务切换是否正常
通过记录发生故障时相关服务的日志记录来分析故障发生时，高可用软件的决策和动作
通过记录发生故障前后客户端的服务使用情况，来判断故障对客户端的影响程度
模拟如下几个灾难：
1、heartbeat服务崩溃
2、mfsmaster主对外服务的网络中断
3、mfsmaster主的drbd同步网络中断
备注：
在测试之前，我会在 mfs 客户端放一个持续输入脚本，它会以一秒的间隔向挂载的mfs目录中的某个文件进行文字输入，以此用来判断 mfs 的恢复时间。
[root@web-phy13-rj ~]# for i in {1..20000};do echo `date` $i >> /mfsdata/testxxxx;sleep 1;done
故障1：heartbeat服务崩溃
模拟故障：
[root@kvm-phy11-rj ~]# /etc/init.d/heartbeat stop Stopping High-Availability services: Done.
故障发生之前的mfsmaster主备服务器状态：
