ML1.2pre5升级到2.6.4出现奇怪的问题

今天刚刚把内核升到了2.6.4，现在出现一些怪问题：
1、我的/home在单独的一个分区，是reiserfs格式的。内核升级完后发现/home里的文件夹变成了安装ml1.2pre5之前的数据。我安装ml1.2pre5前用的是fedora core1，安装ml1.2pre5时没有格式化/home。
2、升级完后我原来ntfs分区里的一些文件和文件夹在linux下看不到了(fedora下也正好是这些文件和文件夹看不到)，升级前还是能看到的。
各位老大看看这是什么原因啊

自己编译的？

你自己编译的内核没有把nls里面的cp936选上吧。

我是按照精华区的这篇文章装的： 安装kernel 2.6.4的整个过程。
刚开始学编内核，make xconfig看得我眼都花了！ ^_^
确实没有把nls里面的cp936选上，第二个问题解决了，第一个到底是什么回事呢？
刚才用2.6.0进去看了一下，发现/home里的文件又回来了，但是回2.6.4里/home还是fedora core1时的文件。

/home在单独的分区？什么文件系统？
可能是没有把相应的文件系统的支持加入内核吧。

tozzq 发表于 2004-4-4 21:16:17

/home是单独分区，reiserfs格式
我在文件系统里面好像没有看到关于reiserfs的选项
如果是没有把相应的文件系统的支持加入内核，那我怎么还能在2.6.4里访问/home呢

That's quite nature, however u mount /home or not, it can be accessed.

可我还是不明白为什么两个内核里看到的/home的文件不一样

before you install ML, you have /home mounted under Fedora, with
some data, when you are installing ML, actually you HAVE NOT
mounted that "/home partition" due to missing reiserfs support in
kernel 2.6.0, after you upgrading to 2.6.4, you have added back
reiserfs support, so you now CAN MOUNT /home, so actually when
you are using 2.6.0, you are putting data on the partition same
as your "/" partition, and under 2.6.4 kernel, since "/home"
CAN be mounted, you can see Fedora's "/home" data in it.

你的意思是不是这样子：我2.6.0下/home的文件实际上不在我原来那个/home的分区里，而是在/下的另外一个/home文件夹里？

yes! to see if i am correct, do this:
boot to 2.6.0, login as root, type "mount", see the output
and then boot to 2.6.4, login as root, type "mount",
see the output again.
you should see something like
/dev/hda4 on /home type reiserfs (rw)
under 2.6.4 but not under 2.6.0.

PS. sorry 对不起，我只能打英文，简体打的不太好。
