MongoDB报错："assertion" : "can't map file memory"

PRIMARY> use identify;
switched to db identify
PRIMARY> db.dropDatabase();
{
        "assertion" : "Can't take a write lock while out of disk space",
        "assertionCode" : 14031,
        "errmsg" : "db assertion failure",
        "ok" : 0
}

-- 磁盘满了
-- 清空磁盘之后，空余2G空间之后，重启mongodb，结果报错如下：
PRIMARY> show dbs';
Thu Mar 21 23:32:34 uncaught exception: don't know how to show [dbs']
PRIMARY> show dbs;

网上找来很多资料，都搞不定，先记下来吧，空了继续去研究。

继续研究，网上很多资料，都说是磁盘空间不足，所以准备把刚导入的3G的collection删除掉，现在在mongo操作界面执行不了，直接进到linux目录删除文件试试看

1 service mongo stop

2 rm -rf identifed.*  --磁盘剩余为6G。

3 service mongo start

4 mongo admin 登陆

5 show dbs;

PRIMARY> show dbs;
admin   0.203125GB
apollo  0.203125GB
apollodev       0.203125GB

 

ok，可以了。
