Aufs下载方式及其简单实例

BOoRFGOnZ

Aufs − another unionfs.
目前aufs只提供CVS方式下载（因为它的作者把稳定版都放入cvs中了）

[code:1] cvs -d:pserver:[email protected]:/cvsroot/aufs login

cvs -z3 -d:pserver:[email protected]:/cvsroot/aufs co -P aufs[/code:1]

编译代码
[code:1]
Currently these configurations are written in ./local.mk, ./local.mk will work
for you in most cases.
        $ make -f local.mk
The local.mk searches your kernel source files by
        KDIR = /lib/modules/$(shell uname -r)/build
If you are cross-compiling the aufs module, try
        $ make KDIR=/your/kernel/source/path -f local.mk
[/code:1]

应用实例
[code:1](after 'make')
        $ man -l ./aufs.5
        # install -m 500 -p mount.aufs /sbin (recommended)
        # insmod ./aufs.ko
        $ mkdir /tmp/rw /tmp/aufs
        # mount -t aufs -o dirs=/tmp/rw:${HOME}=ro none /tmp/aufs

Here is another example.

        # mount -t aufs -o br:/tmp/rw:${HOME}=ro none /tmp/aufs
        or
        # mount -t aufs -o br:/tmp/rw none /tmp/aufs
        # mount -o remount,append:${HOME}=ro /tmp/aufs
[/code:1]

我已经成功把neoshine livecd 更换为aufs了    感觉还是蛮好用的 哈哈

我利用aufs 将neoshine livecd 升级到3。0

重写initrd中的linuxrc 如下
[code:1]#!/bin/bash

echo "Starting system"

大家好，我的aufs怎么用不了，麻烦各位给看看...

我的操作过程是：
[root@localhost aufs]# make -f local.mk
[root@localhost aufs]# install -m 500 -p mount.aufs umount.aufs auplink aulchown auchk /sbin
[root@localhost aufs]# install -m 644 -p etc_default_aufs /etc/default/aufs
[root@localhost aufs]# echo FLUSH=ALL > /etc/default/auplink
[root@localhost aufs]# insmod ./aufs.ko
insmod: error inserting './aufs.ko': -1 Unknown symbol in module
[root@localhost aufs]#mkdir /lib/modules/2.6.27.7-32/kernel/fs/aufs
[root@localhost aufs]# cp aufs.ko /lib/modules/2.6.27.7-32/kernel/fs/aufs/
[root@localhost aufs]#depmod -a
[root@localhost aufs]# mkdir /tmp/rw /tmp/aufs
[root@localhost aufs]# mount -t aufs -o dirs=/tmp/rw:${HOME}=ro none /tmp/aufs
[root@localhost ~]# mount -t aufs -o dirs=/tmp/rw:${HOME}=ro none /tmp/aufs/
mount: unknown filesystem type 'aufs'
/sbin/mount.aufs: bad /proc/2636/mounts
??????????????????????????
