ext3格式下的quota的实现(转)

原创 IT综合 作者:BSDLite 时间:2007-08-12 10:12:07 0 删除 编辑
ext3格式下的quota的实现(转)[@more@]  ext3是由开放资源社区开发的日志文件系统,ext3被设计成是ext2的升级版本,ext3在ext2的基础上加入了记录元数据的日志功能,努力保持向前和向后的兼容性。这个文件系统被称为ext2的下一个版本。
  ext3fs最大的优点是向下兼容ext2,而且ext3fs还支持异步的日志,这意味着它的性能可能比ext2还好。但是使用ext3文件系统时不支持磁盘限量功能。
  red hat从kernel2.4.17-pre8以后支持ext3的磁盘quota,我选择了更为稳定的kernel2.4.18来实现。
  
  <1.源文件>
  kernel-2.4.18:http://www.kernel.org/pub/linux/kernel/v2.4/linux-2.4.18.tar.gz
  quota:ftp://ftp.rpmfind.net/linux/redh ... ota-3.03-1.i386.rpm
  把档案放在/home/src下

  2-1-2)kernel升级过程:
  #cd /home/src
  #mkdir kernel_update
  #cp ./linux-2.4.18.tar.gz ./kernel_update
  #cd kernel_update
  #tar zxvf linux-2.4.18.tar.gz
  #cd linux
  #make menuconfig
  此时出现Linux Kernel v2.4.18 Configuration的窗口

  Load an Alternate Configuration File
  Save Configuration to an Alternate File
  以下都是kernel里的选项,可以根据server硬件的不同自行选择
  
  与quota有关的设定如下
  找到File systems ---> 的字样 (第22行) 按空格键
  把第一行的Quota support前打上*号
  
  • Quota support
      Kernel automounter support
       Kernel automounter version 4 support (also supports v3)
       Reiserfs support
      Ext3 journalling file system support (EXPERIMENTAL)

      
  • JBD (ext3) debugging support
       DOS FAT fs support
       Compressed ROM file system support
      
  • Virtual memory file system support (former shm fs)
       Simple RAM-based file system support
       ISO 9660 CDROM file system support
      [ ] Microsoft Joliet CDROM extensions
      [ ] Transparent decompression extension
       Minix fs support
       FreeVxFS file system support (VERITAS VxFS(TM) compatible)
       NTFS file system support (read only)
       OS/2 HPFS file system support

      
  • /proc file system support
      
  • /dev/pts file system for Unix98 PTYs
       ROM file system support
       Second extended fs support
       System V/Xenix/V7/Coherent file system support
       UDF file system support (read only)
       UFS file system support (read only)
      Network File Systems --->
      
      选定以后选择exit退出。
      
      出现以下:
      ┌──────────────────────────────────────────────────────────┐
      │ Do you wish to save your new kernel configuration? │
      ├──────────────────────────────────────────────────────────┤
      │ │
      └──────────────────────────────────────────────────────────┘
      选择yes
      
      然后出现以下字样:
      Saving your kernel configuration...
      
      *** End of Linux kernel configuration.
      *** Check the top-level Makefile for additional configuration.
      *** Next, you must run 'make dep'.
      
      2-1-2)编译kernel
      #make dep
      #make clean
      #make bzImage
      #make modules
      #make modules_install
      
      2-1-3)cp新的kernel到启动区
      #cp /home/src/kernel_update/linux/arch/i386/boot/bzImage /boot/vmlinuz-2.4.18
      #mkinitrd /boot/initrd-2.4.18.img 2.4.18
      #vi /etc/lilo.conf
      在最后添加以下
      image=/boot/vmlinuz-2.4.18 <= kernel的路径
      label=newkernel <= 启动时的卷标
      initrd=/boot/initrd-2.4.18.img <= kernelimg的路径
      read-only
      root=/dev/hda2 <= / 所在的区
      
      #/sbin/lilo -m /boot/map
      
      2-1-4)重新启动server
      #reboot
      
      重新启动进入时在redhat lilo的选择界面选择newkernel进入
      
      2-2)设定quota

      2-2-1)安装quota。
      #cd /home/src
      #rpm -ivv quota-3.03-1.i386.rpm
      
      2-2-2)设定quota,以home为例
      #vi /etc/fstab
      把
      LABEL=/home /home ext3 defaults 1 2
      改成
      LABEL=/home /home ext3 defaults,usrquota,grpquota 1 2
      重启server
      #/sbin/reboot
      
      2-2-3)设定用户限定
      #quotacheck -uvg /home
      #edquota -u test
      Disk quotas for user chenc (uid 694):
      Filesystem blocks soft hard inodes soft hard
      /dev/hda5 6000 5000 6000 3 5000 6000
      在soft和hard下添上需要限制的磁盘大小(单位是K)
      
      #edquota -t
      Grace period before enforcing soft limits for users:
      Time units may be: days, hours, minutes, or seconds
      Filesystem Block grace period Inode grace period
      /dev/hda5 1minutes 1minutes
      设定soft quota和hard quota之间的时间。
      
      启动quota
      #quotaon -av
      
      
      用test帐号用ftp进行测试,当test目录达到了5M时,提示Disk quota exceeded。
