[SOLVED] How to load dm_mod module?

I'm trying to use LVM: https://wiki.archlinux.org/index.php/LVM. For some commands to work, I need to load the dm_mod module. I have the core/device-mapper package installed. However, `modprobe dm_mod` doesn't load anything. How can I load `dm_mod`?

It's probably already loaded. What is the output of:

$ lsmod | grep dm_mod

Are you running the standard Arch kernel?
Have you recently updated the kernel but forgot to reboot? Compare the output of "uname -a" with "pacman -Q linux".

Ugh, that was it, I needed to reboot. Thanks for the help.
