#故障切换(来自网络中总结)
(1)metalogger服务器中需要备份master的两个配置文件，由于配置文件不是经常变化，因此通过定时脚本进行文件同步即可。

(2)当metalogger没有下载metadata之前，不能使用期接管master。此时metarestore程序会运行失败。

(3)metarestore程序是根据metalogger中定期下载的metadata和changelog来恢复master挂掉时刻master所记录的整个mfs的信息。

metalogger的注意事项

1、部署metalogger的服务器的open files数目必须大于或者等于5000，

2、metalogger在启动时不会下载metadata，而是等到第一个下载周期的下载时间点时再去下载，metalogger下载metadata的时间点是每小时的10分30秒，时间间隔是1小时的整数倍。

3、metalogger不是在启动的时候就取下载metadata，而是必须等到下载时间点(2中所述)才会去下载。也就是说，metalogger为确保正确性，要在启动后最少一个小时以内master和metalogger都要保持良好的状态。
