Linux下mongo启动报：Insufficient free space for journal files

Linux下mongo启动报：Insufficient free space for journal files

原因是因为mongo的journa目录下空间小于3379MB，具体Log如下：

解决办法：

错误原因和解决办法在该LOG中已经说的很清楚了，认真读下可以发现： Please make at least 3379MB available in /home/mongodb/data/journal or use --smallfiles

所以此次我是加了--smallfiles

# ./mongod -port 27017 --logpath /home/mongodb/mongolog/mongod.log --dbpath /home/mongodb/data --fork --logappend --smallfiles
