Compiling 2.6.11 and LVM

[X11]

Okay,

Basically I compiled 2.6.11 and it has one problem, it does not understand the LVM stuff so it just gives an error, how do I enable this support (I noticed the Red-Hat kernel does some Red-Hat related thing), do I need to get a patch or somthing from somewhere, I dont _really_ want to have to download a redhat kernel and sources after downloading the sources off www.kernel.org already (but will if it is a must).

Cheers,
John

You probably didn't create an initrd containing the LVM modules.

More information on creating a initrd?

is it just somthing like

# make initrd

?

A "make install" in the kernel root *should* have created an initrd. It does nothing more than call the /sbin/mkinitrd script. To run it manually you would "mkinitrd kernelversion" where the kernel version is the same as the name of the directory under /lib/modules where the kernel modules reside that you want to make the initrd for. There is also a /sbin/lvmcreate_initrd.lvm1 script that may also do it. I have never ran that one before as I have never personly used a custom built kernel on a machine with LVM partitions. I use regular Linux partitions and ext3 file systems on my laptops/desktops. Plus I normally build the kernel according to this:

Everything gets done magically for me when I do it this way. If you build an initrd manually don't forget to reference it in your /etc/grub.conf for the new kernel you are booting.

I never use make install which might be part of the problem.

I usually just...
make
make modules
make modules_install
cp arch/i386/boot/bzImage /boot/bzImage-2.6.11

edit grub and all that

I'll run a make install for a change

Yeah, "make install" should do that for you, along with create the initrd and add the grub entry.

[x11@kintaro ~]$ uname -sr
Linux 2.6.11

I used to use 'make install' only I got into the habit of doing things manually a while back, can't remember why.
