如何在Linux中设置目录大小限制？ [英] How to set limit on directory size in Linux?

问题描述

我已经阅读了限制目录的大小 - 比如创建大文件，格式化，挂载等..
但是这一切都非常复杂。是否存在实用程序或其他设置限制已有的目录？

I have read about limiting size of directory - like creating big files, formatting,mount,.. etc. But this all very complicated. Does exist utility or something else to set limit on already existing directory?

推荐答案

配额是基于文件系统，但您可以始终创建一个虚拟文件系统，并将其安装在具有usrquota和/或grpquota标志的特定（空）目录中。

Quota is based upon filesystems, but you can always create a virtual filesystem and mount it on a specific (empty) directory with the usrquota and/or grpquota flags.

步骤如下：

1. 创建挂载点


2. 创建一个满载/ dev / zero的文件，足够大到要为虚拟文件系统预留的最大大小


3. 使用ext3文件系统格式化此文件（您可以格式化磁盘空间，即使它不是块设备，但是仔细检查每个危险格式化命令的语法）


4. 挂载在您创建的目录中新格式化的磁盘空间为安装点，例如
   代码：
   mount -o loop，rw，usrquota，grpquota / path / to / the / formatted / disk / space / path / of / mount / point


5. 设置正确的权限


6. 设置配额
   ，诀窍完成。

1. create the mount point
2. create a file full of /dev/zero, large enough to the maximum size you want to reserve for the virtual filesystem
3. format this file with an ext3 filesystem (you can format a disk space even if it is not a block device, but double check the syntax of every - dangerous - formatting command)
4. mount the newly formatted disk space in the directory you've created as mount point, e.g. Code: mount -o loop,rw,usrquota,grpquota /path/to/the/formatted/disk/space /path/of/mount/point
5. Set proper permissions
6. Set quotas and the trick is done.
