I haven't actually made any changes to the kernel yet - I need a working build, hopefully one that matches my current installation, but a working build to start. (Otherwise I won't know if the kernel I'm running and one I've modified contain anything I don't know about....)

I used the config that the installed version had as my base, and I don't think I changed anything. I ran make menuconfig and set the version to something different, then ran make oldconfig to see what changes were needed (none), then built. In theory, if lvm support was in the installed kernel, it should have built into my new one, right?

I'll be making a minor mod to xfs first, then there's a device driver we want to add (I think). I got a ton of "attempt to assign to nonexistent symbol" notices after exiting make menuconfig - I'm assuming that these are harmless.

Thanks again.

My bad - I rechecked and it is the correct source. AND I found that

the

make install (with make modules_install first) takes care of GRUB for me.

BUT:

Now I can't boot because the installed Centos 4.4 was from the distribution DVD, and it depends on the lvm to load. My build doesn't know about the lvm and it refuses to boot - it dies coming up with an error from lvm, followed by two more where it can't find a file

system,

then the kernel panics (and hangs the machine).

How do I get around lvm?

Build your kernel with lvm support. It sounds like you're changing far more than you need to in the config. If you follow the how-to on the centos wiki, you'd only be changing the things you need to, and all else will stay the same. This keeps you from running into things like you're experiencing.

Again, are you certain you need to rebuild? What feature is it that you need?
