有些事情，只有当长时间压力测试的时候，，才能暴露出来。MongoDB集群用了几个月了，但是当写了一个长时间运行的压力测试程序后，几天时间, primary server不能启动。查看MongoDB日志发现错误信息：
Fri Nov 29 10:49:13.182 [initandlisten] ERROR: Insufficient free space for journal files
Fri Nov 29 10:49:13.182 [initandlisten] Please make at least 3379MB available in /var/lib/mongodb/journal or use --smallfiles
原来默认安装的MongoDB使用率/var磁盘分区作为数据保存的分区，而默认Ubuntu下这个分区并不大。所以安装MongoDB集群时要考虑选择合适大小的分区存放文件和日志，比如这里创建一个目录树， /mongodb/data下存放数据，/mongodb/log下存放日志。
root@vm1:/# tree /mongodb/ -L 1
/mongodb/
├── data
└── log
然后将文件移动到对应的目录下，并修改/etc/mongodb.conf文件里面的配置：
dbpath=/mongodb/data/mongodb
logpath=/mongodb/log/mongodb.log
启动服务，正常了。同理修改其他的mongodb server.
