alt_disk_install问题,求高手解决关于-b和-e参数的疑问

烧鸡翼

本人刚接触aix不久

环境:p650分2个lpar,aix5200-01
克隆rootvg成功做过几次了,基本上就是alt_disk_install -C hdiskn,今天想练手测试几个参数,怎知屡屡碰壁,还望高手不惜赐教

测试内容:
1.修改image.data,定制目标盘的文件系统size
2.测试/etc/exclude.rootvg文件,即定制备份文件列表
3.测试-s参数,在克隆rootvg的完成阶段运行一个shell脚本
4.测试在克隆的完成阶段在目标盘安装一个软件包
5.使用-R参数替换/etc/resolv.conf
先做以下的准备:

1.待安装软件包为Mozilla 1.7.13.0
位于/tmp/Mozilla并且/usr/sys/inst.data/user_bundles有其定义:
# pwd
/usr/sys/inst.data/user_bundles
# more Mozilla.1.7.13.0.bnd
#MEDIA=/tmp/Mozilla
#Mozilla 1.7.13.0
I:Mozilla.base
  I:Mozilla.base.rte
  I:Mozilla.base.adt

用smit install_bundle测试该bundle可以安装,
为了在克隆时将Mozilla安装到目标盘,源盘中的Mozilla已经用installp -u命令去除:
# lslpp -l Mozilla*
lslpp: 0504-132  Fileset Mozilla* not installed.

2./etc/exclude.rootvg有以下内容:
# more /etc/exclude.rootvg
/info/

3.目标盘中/etc/resolv.conf将被/tmp/resolv.conf替换
# cat /etc/resolv.conf
nameserver 192.168.0.1

# more /tmp/resolv.conf
nameserver 218.247.141.66
nameserver 202.106.127.1
nameserver 202.96.134.133

4.要运行的脚本在/tmp/post.sh:
# more /tmp/post.sh
#!/bin/sh
rm -rf /alt_inst/tmp/Mozilla
rm /tmp/resolv.conf
rm /alt_inst/tmp/resolv.conf

6.修改/image.data中的fs_data节,我对比df -k命令的输出,将lv size改小了:

        FS_NAME= /
        FS_SIZE= 38472

以上为系统克隆前的状态:
先做简单的:
alt_disk_install -C -B -i /image.data  hdisk1
rootvg被成功克隆
接着试这个:
alt_disk_install -X
alt_disk_install -C -B -i /image.data -e /etc/exclude.rootvg hdisk1
以下为命令输出的信息,rootvg没有被克隆:

我反复试了几次,只要用了-e /etc/exclude.rootvg,克隆就通不过,

再来试其他的:

rootvg被成功克隆,从hdisk1启动系统可以知道/etc/resolv.conf被/tmp/resolv.conf替换掉,post.sh脚本也运行了,但Mozilla没有被安装,

本人对alt_disk_install命令只看过man手册,不太清楚其运行过程调用installp的细节,也查不到有用的资料,郁闷...整到现在,只好冒个泡,求高人解答-_-!

man 已经很全了
仔细看看报错信息就是了
测试完了记得写出结果

烧鸡翼

反复试了很多次,终于有结果了:
1.正确的/etc/exclude.rootvg看起来应该这样:
^./info/
^./backup/
我试过几个失败的版本:
/info/
或者
^./info/
^./backup/
^./tmp/post.sh
^./etc/exclude.rootvg
或者
^./info/$
^./backup/$
^./tmp/post.sh$
^./etc/exclude.rootvg$
或者
/tmp/post.sh
所以是否可以下结论,exclude rootvg中只能排除不需要备份的文件系统,不可以是某些文件?

2.-b参数不是指某个bundle,而是类似installp命令的-f,所以直接给出文件集列表就可以了,
我在/tmp/Mozilla下建立1.7.13.0.bnd,内容为:
Mozilla.base

唉,都是些细节上的错误,不亲自做过还真不知道,今天发现目标盘的fs size没变,继续钻研image.data......

烧鸡翼

再想想也不对呀,如果给-b指定一个bundle,alt_disk_install确实可以找到这个bundle,只是没有找到fileset而已,因为bundle是这么写的:
I:fileset (I表示aix的bundle接口程序将fileset当作installp格式处理)
而installp的-f要求直接列出fileset,所以如果把bundle前面的I:去掉,alt_disk_install应该是可以处理的.....

烧鸡翼

顶一下，看man明明说exclude.rootvg可以排除文件，到底要怎么描述啊？
