Adding second HD and act as one HD
 

Hi,

I want to add a second HD to my linux machine (RH7.3). But I want that my OS is seeing both HD's as one.
How do I need to configure the OS to do this.

Thx

I have the kernel 2.4 so that means that LVM should be installed. But I want to upgrade it. When I try to he asks me for the kernel version. This should be normaly in the /usr/src/linux.

But I use RH7.3 and I cannot find the place where the kernel is installed. How can I know where that is.

Regards

Did you install the development package?

Well yes I followed the steps from the link you gave me. So after the downloading of the lvm_1.0.8.tar.gz file. I unpacket it and run the ./configure. And this was the result of it

Here you can see that he did not found the linux kernel directory and the I tried it with the compiler option then it was
./configure --with-kernel_dir=/usr/src/linux

Thx

When you installed Redhat, did you install the kernel development packages? Those are the packages that would put the kernel source in that directory.
