Did you build the LVM as a module?
If you have LVM as a module, then check the following:
1. Presence of the module
(a) Did you build the kernel modules? "make modules"
(b) Did you install the kernel modules? "make modules_install"
2. Loading of the module. This is either:
(a) Explicitly loaded
There should be a file on your system which lists modules which are
loaded at startup. In general we use a distribution other than
Red Hat so I can't help you with the specifics of your distribution.
(b) Implicity loaded
Module is loaded on demand.
(i) You probably want the "kernel module loader" turned on in the
(ii) You need to configure the module loader appropriately. This
probably only involves ensuring that the module name aliases
are set up right.
In the module name aliases you need:
# The Logical Volume Manager uses these block and char numbers
alias block-major-58 lvm-mod
alias char-major-109 lvm-mod
The module loading tools look in /etc/modules.conf for these
module name aliases. On our systems that file is automatically
generated, so we have to put these aliases somewhere else and
use a tool to regenerate the file. Again I don't know what
your distribution does. RTM.
