linux 2.6.10内核升级手记

年初写的，今天有个同事也要编译内核，满世界找了一遍，结果在cu翻出来了^_^

序言：首先感谢我的两位同事，最近两天给我的无私帮助，如果没有他们，我也许不会有时间来做2。6。10的内核。当然也不会有此文。也希望这篇文章能给遇到相同问题的CU朋友带来帮助。


一。现有的软硬件情况。
1。硬件： hp760g2 8cpu 8g Ram hp smart array 5i +72g hddisk

5. 其他都是默认设置，保存配置。
6. make;make modules_install;make install
7. 重新以新的内核重新启动即可。


三。需要注意的地方，或者疑难解答。

1. mkinitrd

make install 会自动调用mkinitrd 来生成initrd-.img文件，如果第一次编译内核的没有正常启动的话，以后每次执行
make install后，一定要手动执行mkinitrd -f -v /boot/initrd-.img ,来重新生成initrd.img文件。-f是强
制生成并覆盖已有的initrd.img文件；-v是详细输出。

2. modules.conf

modules.conf 文件包含的模块在执行mkinitrd -f -v /boot/initrd-.img 时，会搜索/etc/modules.conf文件，
并按照该文件中的条目从/lib/modules//寻找相应的modules(也就是.o或者.ko文件)，如果找不到就会报：No xxx module
not found的错误。

有2个方法避免这个错误，一是把modules.conf里面的模块全部编译成module，另一种方法是在modules.conf删除相应的module条目，
前提是已经把这个module编译进内核了。

3。关于mount: xx error的错误的说明，xx 为数字，曾经遇到过 3，6 ，22 。因为找不到这些错误数字的具体含义，所以下面的结论都是根据我的经验推断出来的，仅供大家参考。
新内核启动的时候出现这类错误，一般都是因为不能mount ext3 类型的 root filesystem。网上很多资料都说要把ext3 filesystem编译进内核，按照我的经验，编译成动态加载的module也是可行，我的理论依据来自red hat，君不见它的7.2 ,9.0,as3等版本里面lsmod 都会发现
ext3 132868 8
jbd 64244 1 ext3
这说明ext3的支持是可以动态加载的，既然redhat能做到了，我们应该也能吧。这次编译后系统的lsmod结果如下：[root@enuss2 linux-2.6.10]# lsmod
Module Size Used by
autofs 20444 0
e1000 90844 0
parport_pc 31652 0

ext3 132868 8
jbd 64244 1 ext3
cciss 48900 10
