problems in umount proc FS

pandajohn

I've finished setup LFS many days ago.
But I get a problems.

I get error, It's not :
"root:/# umount proc
warning: can't open /etc/fstab: No such file or directory
umount: proc: not mounted

but :
"
"warning: can't open /etc/mtab: No such file or directory
umount: proc: not mounted
"

I don't know that's why. Finally, I've created fstab, so that should be no warning again.
I know /etc/mtab is a link to /proc/mounts, but there is nothing in /proc folder.
Anybody tell me why.

Note: sorry, I can't type chinese in Linux SYS and sorry for my poor ENG.

i think there must be some problem in your /etc/fstab . because proc is a virtual file system which build when you start your system.pls attach your  /etc/fstab and /etc/mtab here.

This is my fstab file. I've no mtab file. It's only a link in /etc, /etc/mtab direct to /proc/mounts file. But there is nothing in my /proc dir.

那个/proc下在没有mount的时候，是空的，mount了以后，就有很多东西了。
[tram@/proc]$ ls -l /proc/mounts
lrwxrwxrwx    1 root     root           11  1月 11 14:27 /proc/mounts -> self/mounts
你是不是在编译内核的时候，把proc的支持给取消了啊？这个缺省是有的，也不能取消的。

thanks , I fixed it.
The problem is I enable reiserfs' stats in /proc/fs/reiserfs in kernel.
