为什么得到错误的mongod死了，但SUBSYS锁定，并没有足够的可用空间，在Linux日志文件？(

我已经安装了Linux CentOS的服务器上蒙戈-蒙戈10gen的，10gen公司的服务器 。

我跟着从台阶链接 。

我已经配置/etc/mongod.conf为-

logpath=/var/log/mongo/mongod.log
port=27017
dbpath=/var/lib/mongo

我已经设置端口为27017 iptables中蒙戈。 要启动蒙戈我的命令 -

service mongod start and
mongo

它开始很好，但几天后，我收到错误 -

当我执行命令 -

service mongod status

它提供了错误 -

mongod dead but subsys locked

请帮我解决的mongod死的问题，但SUBSYS锁定 和杂志可用空间不足，终止

Answer 1:

您可以添加以下所提供的配置文件时运行mongod --config mongod.conf

MongoDB的3.X（最新版）

storage:
   mmapv1:
      smallFiles: true

对于2.6+版

storage:
   smallFiles: true

对于2.4版本少

smallfiles = true

然后，只需执行mongod的接受您的配置文件（这里假设配置的该位置是/etc/mongodb.conf）：

mongod -f /etc/mongodb.conf

文档为smallfiles参数：

Set to true to modify MongoDB to use a smaller default data file size. 
Specifically, smallfiles reduces the initial size for data files and
limits them to 512 megabytes. The smallfiles setting also reduces the
size of each journal files from 1 gigabyte to 128 megabytes.

Answer 2:

开始mongod使用下面的命令实例

mongod --dbpath /data/db --smallfiles

Answer 3:

我在之后的官方指导http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/

使用后

$sudo service mongod start

我去验证是否MongoDB中通过审查该日志已成功启动：

/var/log/mongodb/mongod.log

这是我发现了问题：

2014-11-11T12:54:05.814-0500 [initandlisten] dbexit: really exiting now

解：

在文件/etc/mongod.conf结束时，我加入这一行：

smallfiles = true

在那之后，我重新启动mongod的服务：

$sudo service mongod restart

然后，当我去查看日志，我意识到，一切都很完美，而且问题得到了解决：

Answer 4:

对于有这个问题，尽管有足够的空间用于创建日志文件的任何人。

我的问题：我有足够多的空间，要创建的日志文件。 蒙戈给了我一个连接失败的问题。 我使用kill命令来杀死mongod的过程，反过来给我的SUBSYS问题。 这里是我工作：

转到/var/lock/subsys和删除文件mongod

现在service mongod stop ，然后service mongod start

现在开始蒙戈外壳，一切似乎运行良好。

Answer 5:

第一

cd /usr/local/src/mongo/bin/<br>

然后

./mongod --dbpath /usr/local/src/mongo/data/db/ --smallfiles

Answer 6:

刚一说明，这帮助了我。 尽管有以蒙戈没有相关的技术问题。 这只是系统的空间不足。 清除系统缓存摸索出我和蒙戈回了平稳运行。

yum clean all
